For Meeting of: July 11, 2017 ITEM TITLE: Resolution adopting the 2017 Water System Plan Update with its Appendices and the Water Use Efficiency Goals and Objectives SUBMITTED BY: David Brown, Water/Irrigation Manager, 575-6204 Scott Schafer, Director Public Works SUMMARY EXPLANATION: The Washington State Department of Health requires all water systems to have a comprehensive plan entitled the "Water System Plan" and Water Use Efficiency Goals and Objectives. The City's last Water System Plan was adopted in July 2011 and was required to be updated every 6 years. The Plan preparation was authorized by resolution R-2015-161 with the City required to submit a Water System Plan Update in 2017. WAC 246-290-100 requires that the City Council adopt the Plan and the Water Use Efficiency Goals and Objectives by resolution. The draft Water System Plan Update has been posted on the City web site at https://www.yakimawa.gov/services/water-irrigation/files/Yakima-_W S P_-2017-06-01 _D raft_Plan- and-appendix.pdf for over two months. There have been no public comments. The Plan link was sent to City Council on June 6, 2017. In May, the Washington State Environmental Policy Act (SEPA) was issued, no comments were received. In June, the Community Development Director, SEPA Responsible Official, issued a Determination of Non -significance (DNS). All comments from the DOH have been addressed and incorporated into the final Plan. Recent regulation changes by the State of Washington will now require Water System Plans to be adopted every 10 years instead of 6 years. The City's next Water System Plan update will be due as a result in the year 2027. ITEM BUDGETED: Yes STRATEGIC PRIORITY: Public Trust and Accountability STAFF RECOMMENDATION: Adopt Resolution.

The DOH System Identification number is 991509. The City of Yakima (City), which owns the system, is a municipal corporation. Yakima is a first class city as defined in Chapter 35.01.010 RCW. The City has a Council -Manager type of municipal government as defined under Chapter 35 18 RCW An organizational chart of the Water Division is shown in Figure 1-1 The Water/Irrigation Division Manager is directly responsible to the Public Works Director A copy of the current Water Facilities Inventory (WFI) form is included in Appendix D of this water system plan 1.2 System History The original City of Yakima water system was developed by the Pacific Power and Light Company (PP&L) in the early 1900s. The City purchased the system on July 1, 1926. At that time, the supply consisted of a diversion from the PP&L power canal. In an effort to expand the water supply, the City purchased 343 acres of land at Oak Flats to develop a source on the Naches River A 14 -mile, 24 -inch wood stave transmission main was constructed to transport the supply to twin concrete reservoirs with a combined 24 - million gallon (MG) capacity Three shallow wells, including a Ranney collector were later developed in 1948 and 1950 to supplement the Oak Flats supply The first well developed was the Wright Avenue Well (The water right for the Wright Avenue Well was later transferred to the Kissel Park Well ) The second well developed was located near 16th Avenue and what is now Highway 12 This well and the water right was abandoned in 1969 when this section of Highway 12 was expanded to four lanes It was not being used at the time it was abandoned because of high coliform levels Two deep wells were developed in 1962 and 1965 to further supplement the Oak Flats supply. The first of these was the Kiwanis Park Well (1962) and the second was the Airport Well (1965). Both of these wells are in service today as seasonal/emergency sources of supply. A water treatment plant (VVTP) near Rowe Hill on the Naches River and a 48 -inch transmission pipeline to the City were constructed during the period from 1969 to 1971 to replace the Oak Flats supply. The VVTP is discussed in detail in Chapter 3 of this plan. In 1993, the Kissel Park Well was added to the City's system with a new water right Since then, the city has relinquished the Kissel Park Well water right The City has transferred 900 gallons per minute (gpm) from the Wight Ave Well (discontinued) and 2,000 gpm of the 5,000 gpm Ranney collector well water right to the Kissel Park Well In 2015, the City replaced the Kissel Park Well pump and motor after the equipment had been damaged in a lightning storm This well is also used for seasonal/ emergency purposes and to help meet peak demands July 2017 1 1-1 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan Figure 1-1.

The remaining portion of the Ranney collector well water right (3,000 gpm) was transferred to the Gardner Park Well In 2015, the City began conducting an Aquifer Storage and Recovery (ASR) pilot test at the Gardner Park Well under a preliminary permit issued by the Washington Department of Ecology (Ecology). In January 2017, Ecology issued a final Reservoir Permit authorizing the City to conduct ASR activities. A discussion of the City's ASR program is presented in Section 1.3.1 and Chapter 4. In recent years, the City has not found it necessary to make any major expansions to the water system facilities, in part because of the high level of service that the system is already capable of providing, and also because expansion of the City's water service area is limited by the surrounding water association and municipal water purveyors Potential for expansion is also limited by the "place of use" conditions of the surface water rights in accordance with the 2002 water rights settlement agreement (City of Yakima Water Rights Settlement Agreement with the United States and the State of Washington Department of Ecology regarding the City's Naches River Water Rights in connection with the Yakima River Basin (Acquavella Adjudication). 1.3 Inventory of Existing Facilities This section describes the major components of the City's water system including supply and treatment, the distribution system, and storage The physical facilities as well as the operation of each of these components are summarized here More detailed evaluations and analyses of the water system components are discussed in subsequent chapters: • Water Supply - Chapters 3 and 4 • Storage - Chapter 3, Section 3 6 • Distribution System - Chapter 3, Section 3 7 • Water System Operation - Chapter 6 A map of the water system is presented in Figure 1-2. The ordinance for the City's water system is City Code Chapter 7 68, which is contained in Appendix E 1.3.1 Supply Facilities The supply system consists of a Water Treatment Plant (VVTP) on the Naches River and four active groundwater wells. These facilities are shown in Figure 1-2 and described in the following subsections. Naches River Water Treatment Plant The capacity of the Naches River WTP is 20 million gallons per day (MGD). However, the plant is laid out to allow space for expansion to 60 MGD capacity if demand warrants increased supply capacity and subject to the availability of the necessary water right. Treated water from the plant flows over a weir into a 48 -inch transmission main and to the City by gravity. In 2011, a flood event damaged existing air/vacuum release valves on the 48 -inch transmission main at the Naches River crossing In response to this event, the City installed new valves on the transmission main on each side of the river crossing to allow for an emergency bypass in the event of future damage to the transmission main In 2014, the City upgraded the backwash settling basin and electrical service at the WTP. This involved constructing multiple concrete lined basins and a recycle pump station to July 2017 1 1-3 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan replace the original unlined basins and residuals handling process. The City also upgraded the electrical service at the WTP to be large enough to provide reserve capacity Along with the new electrical service, the City also installed a new larger emergency backup generator system. The city also upgraded the Supervisory Control and Data Acquisition (SCADA) system and associated equipment. In 2015, Yakima County completed the Eschbach Park Levee Setback and Restoration project Eschbach Park is located across the Naches River from the WTP Prior to this project, the levee adjacent to the WTP did not meet requirements to be designated as a 100 - year flood levee By modifying the levee at Eschbach Park, the levee adjacent to the WTP now qualifies as a 100 -year flood levee, thereby reducing the risk of flooding at the WTP Groundwater Wells The City of Yakima water system currently has four wells. The wells are located at the Airport, at Kiwanis Park, at Kissel Park, and Gardner Park. Table 1-1 shows the capacity, zone served, and other pertinent information about the City's wells. A discussion of the hydrogeology of the aquifers from which these wells withdraw water is presented in Chapter 4 Aquifer Storage and Recovery Program The City has developed an Aquifer Storage and Recovery (ASR) program to provide additional water supply and improve water system reliability The ASR program involves diverting water from the Naches River during low demand periods (e g , the winter), treating the water to drinking water standards at the Naches River WTP, delivering water through the City's distribution system to groundwater wells, and injecting (recharging) water through the wells into the aquifer (reservoir) The City could then withdrawal groundwater at a later time for municipal use The City has conducted extensive hydrogeologic studies and been in close coordination with Ecology for over 15 years in the course of developing the ASR program. After conducting initial pilot testing in 2000-2001, the City submitted Reservoir Permit Application R4-3552 to Ecology on April 12, 2002 The proposed storage reservoir is the Upper Ellensburg aquifer in the Ahtanum-Moxee subbasin More recently, Ecology issued a preliminary permit to the City in May 2014, allowing the City to conduct additional recharge and recovery testing at the Gardner Park Well. This was followed by Ecology's issuance of a temporary permit to the City on February 24, 2015, allowing recharge activities to occur at the Gardner Park and Kissel Park Wells. The City began recharge operations on March 10, 2015, under the conditions of the 2015 temporary permit. Approximately 41 million gallons of water were recharged at the Gardner Park Well in the spring of 2015. In January 2017, Ecology issued a final Reservoir Permit (R4 -34552P) authorizing the City to recharge up to 14,400 acre-feet per year using the Gardner Park, Kissel Park, and proposed Southeast Area wells. The Reservoir Permit also authorizes the City to use all of its wells for recovery of stored water. Recent development and permitting activities have been coordinated with the Yakima River Basin Integrated Water Resources Management Plan (Integrated Plan), as described in Section 1.4.9.

A water system hydraulic profile is shown in Figure 1-3. The relationship between the pressure zones is discussed in this section. First Level Pressure Zone The gravity supply from the 48 -inch -diameter transmission main flows to the 6 -MG 1st Level Reservoir located at North 40th Avenue and Englewood Avenue This reservoir supplies water to the 1st Level zone Flows from the WTP are manually adjusted to maintain a nominal hydraulic elevation of 1,264 feet, resulting in a static pressure range in the 1st Level zone of approximately 54 to 110 psi During emergencies, the 1st Level zone can also be served from the four wells In extreme emergencies, such as fire -flow conditions, the 1st Level zone can also be served by the nine pressure -reducing valves (PRVs) which allow water to flow from the 2nd Level zone The 1st Level zone can also be served by opening the valve that controls the intertie from the Nob Hill Water Association Second Level Pressure Zone The 2nd Level pressure zone is served by the 40th Avenue Pump Station and the Stone Church Pump Station. The 40th Avenue Pump Station draws from the 48 -inch supply transmission main and pump operation is controlled by the WTP operators based on the water level in the two 12 -MG 2nd Level Reservoirs. The nominal hydraulic elevation is 1,380 July 2017 1 1-7 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan feet, which results in a static pressure range of 43 to 105 psi. The Stone Church Pump Station was installed in 2000 to improve reliability and the ability to satisfy emergency demands This pump station provides another alternative to supply the 2nd Level zone The Stone Church Pump Station is equipped with a 250 kilowatt (KVV) emergency generator to allow for operation during electrical power outages. During emergencies, the 2nd Level zone can be supplied by three PRVs from the 3rd Level zone During extreme emergencies, the 3rd Level zone can supply some of the 2nd Level zone's needs for approximately one day of average water use Third Level Pressure Zone The 3rd Level pressure zone is served from the 2nd Level zone by the 3rd Level Pump Station, located at the site of the two 12 -MG 2nd Level Reservoirs. In 2014, the City replaced the 3rd Level Pump Station motor control center and emergency power transfer switch. In addition, the 3rd Level Pump Station includes a 250- kW generator to provide emergency power. The 3rd Level Pump Station operation is controlled based on operating levels in the two 1 -MG 3rd Level Reservoirs The nominal hydraulic elevation is 1,531 feet, resulting in a static pressure range of 70 to 115 psi During emergencies, the 3rd Level zone can be supplemented by opening the valve that controls the intertie from the Nob Hill Water Association. During fire demand periods, water can be supplied to the 3rd Level pressure zone from the 2nd Level pressure zone through the three 2 -way PRVs which connect the two zones. Gleed Pressure Zone The Gleed community, with a service capacity of 100 residential units, is served from the 48 - inch transmission main through the Gleed Pump Station. Two 80- gpm pumps provide the average and maximum day demands, with a 2,000-gpm pump reserved for fire flow. A hydropneumatic tank is used to regulate pressure in this area No storage facilities are located in the Gleed community 1-8 1 July 2017 Figure 1-3.

However, in 2011, the City began a program to replace or upgrade essentially all of the existing water meters with advanced metering infrastructure (AMI). The City completed this program in 2015. The new AMI system allows for real time monitoring and geographical analysis of consumption data and will contribute information useful in future water system planning Chapter 4 of this Water System Plan provides additional information about the City's AMI program In 2017, the City plans to initiate the steel main replacement program. This program will involve the replacement of steel, galvanized iron, and unlined cast-iron pipelines that are 4 inches in diameter or less. The pipelines identified for replacement are located mainly in the business district and in portions of the older residential districts. The City plans to replace these pipelines with 6 -inch (minimum) ductile iron pipe. The City aims to replace 500 to 2,000 linear feet of pipeline each year. Booster Pump Stations The booster pump stations provide water to the 2nd Level and 3rd Level zones and to the Gleed community, as shown in the hydraulic profile in Figure 1-3. The pump station location, the supply location, the zone that is served, the number of pumps in each station, pump capacity, and other characteristics are listed in Table 1-2 Pressure -Reducing Valves Emergency supply from the 3rd Level to the 2nd Level zone and from the 2nd Level to the 1st Level zone is provided by 12 PRVs located throughout the water system, as shown schematically in the hydraulic profile in Figure 1-3 There is one additional PRV that serves the intertie connection between Nob Hill Water Association and the 1st Level zone The PRVs are set to open and close at various hydraulic elevations Table 1-3 shows the location, size, inlet and outlet pressures, and other characteristics of each PRV The purpose of the PRVs is to provide additional flow for emergency purposes. The reduction of pressure in a zone under emergency conditions because of a fire flow or other large water need causes the hydraulic elevation to decrease Reduction in hydraulic elevation will cause the normally closed, hydraulically activated valves to open and provide additional flow into the zone In addition to the 12 PRVs, there are three additional connections between the 3rd Level and 2nd Level zones • Check valve at Lincoln Avenue and North 40th Avenue to allow water to flow from the Middle zone to the 3rd Level zone under emergency conditions (i e , very low 3rd Level zone pressure) • Closed valve with a 2 -inch -diameter bypass for winter operation at Westpark Alley and North 40th Avenue. • Closed valve at Summitview Avenue and North 44th Avenue. 1-10 1 July 2017 2nd Level Reservoirs 1 • 40th Avenue Pump Station Gleed Pump Station ill I 1 •=iNNr 1I� Gleed `�, ' wl■11T ■I ■II■■ '` �i `'\l � Stone Church �■=�i� i1�i11 \ ���~ . :1 �L IOW Pump Station 1:�7=1 _��! • 7 1W W 3rd Level L� r __P Ir1ig_ 1:21`:i,-i�-■■■� `; ��0*TA As���� ` Reservoirs J'C�i7I�IICI C_.�il .�■,� __.... \• 0,0*00t � L ill�,�5■ 1♦ I fes■ a'I -___,••:'�`` \ ��••,'�.� `r` ~ s to �• r�■■ gildrPLevel�!!111�r;Itillllilnli `1o:; \* *i;,*>i��„l P ��;eservoir ilLv ��� ,�'�� ���Yi. nusizia �� * ',� \�� '' 4,011 � Kiwanis Park Well 1u1■1111 1119rr]1� 11�1l11■11lg it 11��Vatrrsi;At ■ �� 1 ■ Ilfa % 11........lailliia"R ■ i%Allugi■.■■_• L_UI!IIJIiII111u11Hhik1I �_'\l 1II11611111A1e!1s....Is■IIYIIII�!1i1er ■ ■ iii 11�6"nl;: 1111111111111 � i1` !1 Ei r nm— \w !1111311 !�_ ����I _:�71■ ;;�■11;—II�IIi�IIIIIIIIIIIIIII � � � I .. 11 a G11rd1 111111111■ 111111 �� - -v ir. vg...ln __Ii1IlIII■IIIIIImin \ r"-"hhh" " k11111 ME i '_ 111_ Airport WellIr&' /111111/ Gardner Park Well t 11/1 ▪ a .._._._._,_ _.,1111 ::! r II i • es 1 LEGEND City Limits Boundary Waterlines Diameter (in Inches) 6 8 — 10 — 12 — 16 – 18 — 20 24 30 48 54 DATA SOURCES City of Yakima (2016), WSDOT (2015) DISTRIBUTION SYSTEM PIPING FIGURE 1-4 YAKIMA WATER SYSTEM PLAN 05 1 15 2 MILES Fez PATH G IPROJECTSIWASHINGTONICITV__OF_YAKIMA_0065391WSP 201]_2]16651] 2_WPIMAP_DOCSIWSPIFIGUREI-4 MXD USER DKUHNS DATE 1112912016 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan — DRAFT Table 1-2.

Radio communications are used to transmit data between the main control panel and the remote sites (reservoirs, pump stations, and supply wells). In 2014, the City upgraded the computers and PLCs at the WTP and all remote sites. 1.3.6 Interties with Adjacent Water Systems As discussed previously, the City has common boundaries with, or is approximately adjacent to, four other water purveyors: • Nob Hill Water Association • Terrace Heights area (Yakima County) • City of Union Gap • City of Selah Other smaller Group A water systems adjacent or near the City's water system include • Noel Canning (#07143) • The Ice Rink (#99114) • Regal Mobile Estates (#71725) • Whispering Pines (#42948) 1-14 1 July 2017 • Laura Lee Mobile Home Park (#46219) • American Legion (#01985) • Gleed Mobile Estates (#27828) • Apple King LLC (#62020) Fr 1M Yes Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan • Bertsch Subdivision Water • Suntides Mobile Park (#86280) Association (#05885) • Raybung Community Well (#70630) • Sun -Tides RV Park (#85138) The City has two interties with the Nob Hill Water Association. A summary of the interties, including location, size, hydraulic grade line (HGL), adjacent purveyor, and other data, are included in Table 1-5. The 32nd Avenue and Ahtanum intertie is automatically activated during certain types of fire flow events. The other intertie is activated manually. The City of Yakima HGL elevations shown in the table are based on the HGL at the storage reservoir when full and under static conditions. No previous communications have taken place between the City and nearby purveyors for regionalization of water systems. The City does not currently have any plans for regionalization to occur. If such discussions were to take place, Yakima County, as a Satellite Management Agency (SMA) would lead such efforts. Table 1-5. Interties Pressure Zone Adjacent Purveyor HGL (ft.)

Zoning map amendments 2 Zoning ordinance amendments 3. Development standards 4 Critical area ordinance 5. New subdivision ordinance 6 Transportation capacity management ordinance 7. Regulatory reform procedure 8. Future land use map 9 Comprehensive plan text changes 10. Revised transportation plan July 2017 1 1-15 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan 1.4.2 Yakima Urban Area Zoning Ordinance The Yakima Urban Area Zoning Ordinance (Yakima Municipal Code Title 15) was revised December 28, 1998, to comply with the requirements of the GMA as discussed above The Yakima Urban Area Zoning Ordinance was most recently updated in 2010 1.4.3 Yakima County Comprehensive Plan Yakima County's currently adopted Comprehensive Plan - Plan 2015 - is a policy document that guides county decisions related to growth and development in unincorporated Yakima County The County is currently preparing an update to Plan 2015, titled "Horizon 2040," which should be available by June 2017 The County's Comprehensive Plan was developed to provide the policy framework for how the County would develop in the future It contains land use maps as well as the other planning elements required by the GMA Another integral part of the long range plan for Yakima County, are the plans of the individual cities. Although not technically part of the County's Comprehensive Plan, each city in the county has adopted a comprehensive plan that defines their vision of the future Yakima County is a partner with the City of Yakima in the adoption of the Yakima Urban Area Comprehensive Plan, which includes separately adopted neighborhood plans 1.4.4 West Valley Neighborhood Plan The West Valley Neighborhood Plan and Area -Wide Rezone were adopted on February 15, 2011 They became effective on February 28, 2011, in the unincorporated area, and on March 20, 2011, inside the Yakima City limits The West Valley Neighborhood lies outside of the Yakima Water System Service Area and is served by the Nob Hill Water Association 1.4.5 City of Yakima Wastewater Collection System Master Plan The City adopted the Wastewater Collection System Master Plan in October 2013. The Yakima Regional Wastewater Treatment Plant (WWTP) is owned and operated by the City and provides treatment services for the City of Yakima, the City of Union Gap, the City of Moxee, unincorporated lands to the east of the City of Yakima, referred to as Terrace Heights, and several other unincorporated areas under the jurisdiction of Yakima County including the area to the west of the City of Yakima known as West Valley The City provides sewer service to these areas based upon an inter -local agreement known as the "Four Party Agreement" which was agreed upon and entered into on February 23, 1976, by the City of Yakima, Yakima County, the City of Union Gap, and the Terrace Heights Sewer District to allocate capacities and service areas The regional sewer service boundaries are shown in Figure 1-5. Since the regional wastewater treatment facilities are intended to serve the entire urban area, the service area boundaries and the associated population projections are considerably larger than those of the City's water system As such, the service area and population projection considerations presented in this Water System Plan are not directly comparable to the wastewater system The urban areas not served by the City's water system are served by the adjacent water purveyors which include the City of Union Gap, the Nob Hill Water Association, and Yakima County (Terrace Heights water system) 1-16 1 July 2017 LEGEND L. .

The purpose of this plan is to identify potential sources of contamination near the member purveyors' groundwater supplies, implement management strategies to prevent contamination of those supplies, and develop a contingency plan for contamination mitigation in the event that groundwater does become contaminated. In this Regional WHPP, each member community in the Upper Yakima Valley plays a role in protecting the groundwater supplies of the entire area by pooling resources and management efforts to target an audience beyond that which could be reached at a local level The member purveyors participating in this wellhead protection plan include • Yakima County • City of Yakima • Town of Naches • City of Moxee • Town of Tieton • City of Union Gap • City of Selah • Nob Hill Water Association Regional management efforts adopted by the eight purveyors forming the Regional Wellhead Protection Committee include: • Development of a Geographical Information System (GIS) database of the wellhead protection areas, potential contamination sources, and water quality data in order to monitor and track sources and receptors. • Development of a planning trigger to distribute wellhead protection notification letters for development changes (i e , building permits, zoning changes, SEPA, etc) within wellhead protection areas • Coordination with Ecology to prioritize their Hazmat Technical Assistance Sweep within wellhead protection areas • Coordination with the State Health Department's Sanitary Surveys to ensure up-to- date information is maintained in the regional GIS potential contamination source inventory. • Coordination with County Health District to identify septic tanks and private wells with Global Positioning System (GPS) units. • Coordination with the Washington Association of Realtors to adopt a Property Disclosure Addendum that will help identify private and abandoned well locations during property transfers • Designation of the 6 -month wellhead protection area as a critical "Red Zone" by County Emergency Management (LEPC) in order to prioritize wellhead protection during emergencies (i e , hazardous material spills) Outreach to educate the public, including the distribution of literature • Coordination with Education Services District (ESD) which provides continuing education to area teachers in order to better integrate wellhead protection and water issues into school curriculum. 1-18 1 July 2017 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan • Development of a regional website to increase public awareness on the need to protect groundwater • Development of a logo for wellhead protection area signs • Development of an interlocal agreement among the eight purveyors to make sure that wellhead protection is given a high priority in the Upper Yakima Valley 1.4.7 County Water and Sewer Veneral Plans The Yakima County Rural Water & Sewerage General Plan was adopted by Yakima County in May 1988 This plan was subsequently amended by the Yakima County Water System Satellite Management Plan which was completed in December 1996. This satellite management plan, prepared in accordance with the requirements of WAC 246- 295, was approved by DOH thereby authorizing the county to become a satellite management agency (SMA) A SMA is an individual, purveyor, or entity approved by DOH to own or operate more than one public water system on a regional or county -wide basis The County's SMA includes all of Yakima County except the incorporated area, the Yakima Training Center, and certain areas of the Yakama Indian Nation Under its satellite management plan, the County will acknowledge the service area boundary of any existing water system that has a DOH approved water system plan Developments located within a defined service area boundary will be referred to that water purveyor for service, thus allowing the existing water purveyor the first right for providing water service Yakima County currently operates 28 satellite water systems. Six of these systems are within the City of Yakima Urban Growth Area. These are the Terrace Heights, Bittner, Oliver, Horizon View, Norman, and Star Crest Water Systems. The County does not currently operate any water systems which it does not own. 1.4.8 Groundwater Management Plans In 1999, United States Bureau of Reclamation (USBR), Ecology, and the Yakama Nation signed a Memorandum of Agreement (MOA) to fund and oversee a study of the groundwater resources of the Yakima River Basin. In 2011, the U.S. Geological Survey (USGS) completed a study of the availability of groundwater resources and of the interaction or "continuity" between groundwater and surface water in the Yakima River Basin Through computer modeling of groundwater flows, the USGS found that generally the surface and groundwater resources in the Yakima River Basin are interconnected such that increased groundwater pumping results in decreased surface water flows The USGS model can be used as a tool by water -management agencies and other stakeholders to quantitatively evaluate proposed alternative management strategies that consider the interrelation between groundwater availability and surface -water resources 1.4.9 Yakima River Basin Integrated Water Resource Management Plan In June 2009, Ecology and Reclamation brought representatives from the Yakama Nation, irrigation districts, environmental organizations, and federal, state, county, and city governments, including the City of Yakima, together to form the Yakima River Basin Water Enhancement Project (YRBWEP) Workgroup to help develop a consensus -based solution to the basin's water problems. In 2011, the YRBWEP Workgroup developed the Yakima River Basin Integrated Water Resource Management Plan (Integrated Plan). The Integrated Plan encompasses seven elements: (1) habitat and watershed protection July 2017 1 1-19 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan and enhancement, (2) reservoir fish passage, (3) surface storage, (4) enhanced water conservation, (5) structural and operational changes, (6) groundwater storage, and (7) the use of market-based forces to reallocate water and habitat among willing buyers and sellers. The goals of the Integrated Plan are to protect, mitigate, and enhance fish and wildlife habitat; provide increased operational flexibility to manage instream flows to meet ecological objectives; and improve the reliability of the water supply for irrigation, municipal supply and domestic uses. The seven plan elements each include recommended projects to meet the goals of the Integrated Plan. As an example, the groundwater storage element of the Integrated Plan includes the development of an ASR program in the City of Yakima. 1.4.10 Basin Plans In 1998, the Washington State Legislature passed the Watershed Management Act (RCW 90.82, [ESHB 2514]) (WMA). The WMA identifies the "initiating governments" that select a lead agency, apply for grant funding, determine the scope of planning, and convene a "Planning Unit." In the Yakima Basin, the Tri -County Water Resource Agency (TCWRA) represents the initiating governments under WMA. Representation on the TCWRA includes Benton, Kittitas, and Yakima Counties; the Cities of Yakima and Ellensburg; Sunnyside Valley Irrigation District, Roza Irrigation District, and Yakima- Tieton Irrigation District. The Yakima Basin Water Resources Agency (YBWRA) was formed to replace the TCWRA when the members in Kittitas County dropped out of the program In 2003, the Watershed Management Plan, Yakima River Basin was adopted by Yakima and Benton Counties. The Detailed Implementation Plan (DIP) was developed and adopted in 2007. The DIP was being administered though the YBWRA until Ecology stopped funding local Watershed Agencies in 2010. As such, there is not an operating Lead Agency for the purposes of adopted watershed plan implementation needs. Instead, the water quality related (instream flow management, surface and groundwater diversion or withdrawals, storage and water banking) watershed plan implementation needs and objectives are being addressed under the Integrated Plan implementation effort. In addition to regional watershed planning efforts, the City works with agencies and organizations operating in the Naches River Watershed to protect the City's surface water source The City's Watershed Control Program is documented in Chapter 5 of this Water System Plan. 1.4.11 Water System Plans for Adjacent Purveyors City of Union Gap The City of Union Gap's most recent water system plan update was completed in June 2011. The area presently served by the Union Gap water system is shown in Figure 1-6. Nob Hill Water Association Nob Hill Water Association Water System Plan Update was completed in 2015 The area presently served by the Nob Hill Water Association water system is shown in Figure 1-6 Yakima County Yakima County's Water System Plan was completed in 2009. The County is currently updating the Yakima County Water System Plan The County aims to complete the Water System Plan update by early 2017 The area served by Yakima County water system is shown in Figure 1-6 1-20 1 July 2017 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan City of Selah The City of Selah's most recent Water System Plan update was completed in 2014. The area presently served by the Selah water system is shown in Figure 1-6 1.5 Existing Service Area Characteristics The City's water system is within the Yakima Urban Area, as defined in the Yakima Urban Area Comprehensive Plan, which was adopted in April 1997 and amended in 1998, 2000, 2001, 2002, 2006, and 2010. The City of Yakima is currently updating the Yakima Urban Area Comprehensive Plan. The City aims to complete the plan update by 2017. The Urban Growth Area and city limits are shown in Figure 1-6. The Washington State GMA, passed in 1990, requires municipalities to establish boundaries within which "urban services", such as water supply, will be provided. The City's existing water service area shown in Figure 1-6 is delineated by the boundary of plats currently served by mains and service connections. The existing service area extends beyond other boundaries such as city limits, urban boundary, and future service boundary. For example, City service is provided to county areas, such as the Gleed community. If the existing service area extends into an adjacent purveyor's future service area, it is by mutual verbal or written agreement until the adjacent purveyor's system is extended. The City does not have plans to pursue regionalization at this time. For the purpose of this plan, the existing and future water service areas are essentially the same. 1.5.1 Adjacent Purveyors Four water purveyors supply water to areas adjacent to or within the City of Yakima: Nob Hill Water Association, the City of Union Gap, Yakima County in the Terrace Heights area, and the City of Selah. The existing service areas of these purveyors are shown in Figure 1-6. Nob Hill Water Association The Nob Hill Water Association serves the West Valley area west of Yakima A significant portion of the system is located within the City's corporate limits and the remainder is located in unincorporated Yakima County The system is operated as an association with a board of directors In 2013, the Association had approximately 9,750 connections, serving a population of 29,460. Nob Hill Association's 2015 Water System Plan Update projects an average growth rate of 2.6 percent through the year 2035. The systems' five active wells have a capacity of 8,050 gpm. The distribution storage consists of six reservoirs with a total capacity of 4.23 MG. The City has two interties with the Nob Hill Water Association The two interties are located at West Lincoln Avenue and North 56th Avenue, and South 32nd Avenue and Ahtanum These interties are for emergency purposes only and are covered in a Memorandum of Understanding between the City and the Association dated September 6, 2000, a copy of which is included in Appendix F These interties are not designed for normal operation of either system and are not considered as a source of supply in the storage and supply analyses presented in Chapter 3 of this plan In the past, whenever an intertie has been activated, it has been a joint effort. Crews from Nob Hill and the City have been present to open the two valves (each with a locking cap) and to check system pressure. The interties are not metered. Instead, the City has estimated supply by comparing the current pump records to the previous year's pump records during the same time period, or by estimating supply using the systems hydraulic models. July 2017 1 1-21 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan City of Union Gap The City of Union Gap is located in the southeast corner of the urban area. Union Gap's water system supplies approximately 2,760 connections The source of supply is five wells with a combined capacity of approximately 4,855 gpm and a reservoir capacity of 1 6 MG The City does not have any interties with Union Gap. However some water could be delivered to Union Gap in an emergency through a connection between fire hydrants near Washington Avenue. Terrace Heights Area (Yakima County) Until recently, the Terrace Heights area consisted of four water systems with greater than 100 services and approximately 20 water systems that served between 10 and 99 customers The major systems were the Country Club District, Terrace Estates, Sun Country Mobile Estates, and Skyline Mobile Estates There were also a number of systems that served mainly commercial establishments or had fewer than 10 connections. Yakima County has developed a well in the Terrace Heights area, purchased two of the water systems, and intends to serve the area within the urban boundary east of the Yakima River. The County's future service area for Terrace Heights extends westward to the City's service area boundary Overlaps and islands of service do not exist and are not anticipated The county utility is expected to grow into a major purveyor within the urban boundary City of Selah Selah is located east of the Gleed community and North of the City of Yakima (see Figure 1-6) In 2012, the City of Selah had approximately 2,450 services, serving a population of 7,290 Because Selah is located across the Naches River and is outside the current water service area and urban area, it is not expected that the City will provide water service to this area 1-22 1 July 2017 c\_ Yakima County ,--.... v,_...v r...._ H. •� �r—'—' Cr11<UrriR!1L■�I Eill� •• ��`1• •••�.y i 1` y �+---- •��■1�il� kIIIri11111111111:1=�_�•.•••��`� •••�•,••,•,0 lc — n. in m loin! m �1lo :igyiquival •••••.�eloo••..�on oln 11 1111111111 —111 r71s 11� 11■1 �", iniin/r••*A1►•�ii ��••••l.•• RIIIIMMIII ■i1Y1111JC■11111■11■11111i11111inStiivatilli \ ' •tiiiiii..i� SHE . 11 1n n !IY ■,wA wit I1j'111111111: ismi7 , 1 mur 1 - dra �__ j.,1■ 1� IIA I 111 .■'!mp! \ \1■..._ 1 _ +err .IiiIi11111111w111 Iium.Ii !iii II11111111 win • Nob Hill �.-- — - �urlrrrrlei■Is�ll■111 „ ��1� �N._ 5•+r� impEEL�1n■iiniu1n1■. 1111111111111 '1`�N11113i _ Li11 11111111 �� ,� \I T�- BA—Em �11Ell I 111111 % "" : LEI fill _ml 111111_—' 4fiaN- 11- 111111111 1 = 1;111!111111111111 1 LEGEND City Limits Boundary Urban Growth Area Water Service Area Yakima Nob Hill Selah I Union Gap Yakima County ■ Moxee DATA SOURCES City of Yakima (2016), WSDOT (2015) ADJACENT PURVEYOR SERVICE AREAS FIGURE 1-6 YAKIMA WATER SYSTEM PLAN 0 05 1 15 2 MILES F�2 PATH G IPROJECTSIWASHINGTONICITY OF_YAKIMA_0065391WSP 201]_2]16651] 2_WPIMAP_DOCSIWSPIFIGUREI 6 MXD USER DKUHNS DATE 552017 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan 1-24 1 July 2017 This page left intentionally blank Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan 1.6 Future Service Area The areas currently designated or planned to be included in the City's future water service area are discussed in this section and are shown in Figure 1-6. 1.6.1 Potential Service Area The future service boundary describes the specific area for which water service is planned by a public water system (WAC 246-293) The future service boundary is important to meet the requirements of the GMA, and it is critical to the efficient and cost- effective development of the water system Annexations by the City of Yakima or its neighboring cities will not affect that water service area, because the water service boundaries are established by separate agreements. Four other utilities provide service within or near the urban boundary Service agreements have been or are being developed among the utilities to determine which utility will serve new areas of growth The criteria used to determine the City's future service boundary include: • Place of Use - The "place of use" boundary (see Figure 4-1 in Chapter 4) defines the specific area within which the City is allowed to utilize its surface water supply. • Physical features - Boundaries formed by physical features are usually expensive and often impractical to cross • Adjacent jurisdictional boundaries - Jurisdictional boundaries include other city limits and adjacent purveyor future service areas It is inefficient and perhaps impossible politically to serve in areas already planned for service by adjacent purveyors • Urban Growth Boundary - The GMA requires that the water utilities establish common future service boundaries within the growth management planning area designated by the Urban Growth Boundary. • Policy - The City's current policy is to provide service outside the existing service area only where it is economical and practical. Resolution No. D- 1250, adopted March 29, 1965, describes the City policy regarding service outside the existing city limits (Appendix G). The alignment of different sections of the City's future service boundary is based on different combinations of these criteria The main sections of the City's future service boundary in terms of these criteria are discussed below North Boundary The Naches River, the urban growth boundary, the adopted urban area of the City of Selah, and the City of Yakima boundary define the north section of the future service boundary. East Boundary The east boundary is defined by the Yakima River and the City of Yakima boundary This boundary is coincident with Yakima County's future service boundary for Terrace Heights July 2017 1 1-25 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan South Boundary The south boundary primarily depends on adjacent jurisdictional boundaries and policy. The Water Service Agreement between the City of Yakima and the City of Union Gap dated April 21, 1987, (Appendix F) did not completely define the service areas of the Cities of Yakima and Union Gap As a result, some disagreement arose over which purveyor would provide service to some areas These disagreements are described in the following sections Although Union Gap recently annexed all of the land south of Washington Avenue, water service is still provided to some areas by the City of Yakima On South Side or Washington Avenue, the current service area of the City of Yakima extends into the Union Gap service area as defined by the agreement (as shown in Figure 1-6). By verbal agreement, the City of Yakima serves all parcels abutting the south side of Washington Avenue east of South 16th Avenue and west of Voelker Avenue. Thus, the necessity for both cities to install a main in Washington Avenue is avoided. Some parcels south of, but not adjacent to, Washington Avenue are served by the City of Yakima by verbal agreement between the two cities. It is understood that, when the City of Union Gap system is extended to these areas, the ownership of the mains and services will be transferred from the City of Yakima to Union Gap. West Boundary The Nob Hill Water Association operates and maintains a water system in the western part of the City of Yakima under a 25 -year franchise agreement (City of Yakima Ordinance No 93-86, December 1, 1993, Appendix F) The association's service area also extends well beyond city limits Generally, as shown in Figure 1-6, the City's future service boundary is the same as the existing boundary There are several areas that can be served by either utility Some of these areas are "islands" completely surrounded by the other utility's service area Other parcels abutting the future service area boundary may be served by either utility, creating an erratic boundary In this case, the boundary might alternate from a street centerline to the back property line on either side of the same street Nob Hill Water Association and the City have verbally agreed to maintain the status quo Most of the parcels currently receive water service, and the distribution grid is well established Where in- fill services are requested, the customer is given the choice of utility where both utilities have water mains in the same street 1.7 Service Area Agreements The City currently has written service area agreements with the Nob Hill Water Association and with the City of Union Gap Copies of these agreements are included in Appendix F There are currently no comprehensive service area agreements between the City of Yakima and the other two adjacent purveyors, the City of Selah and Yakima County. 1.8 Service Area Policies The City's service area policies are applicable to various sections of this water system plan update and may also be referenced and discussed in more detail elsewhere in this document However, the policies are presented together here in one location in a summary form with reference made, where applicable, to other documents which the City 1-26 1 July 2017 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan provides for distribution to persons interested in developing within the water service area A brief summary of each applicable service area policy is included below Wholesaling Water The City does not currently provide water to any other utilities on a wholesale basis, and does not anticipate doing so in the future Wheeling Water: The City currently does not allow the system's mains to be used to wheel water to another water system. A need to consider any wheeling arrangements with adjacent purveyors is not anticipated during the planning period. Annexation It is City policy that before utility service is provided to a contiguous, unincorporated property annexation is required For noncontiguous properties the City would require an outside utility agreement (OUA) However, the City does not provide water service outside of the defined service area (see Figure 1-2) and, with only a few exceptions, the City's water service area is entirely within the City limits Significant areas in the western portion of the City are actually served by the Nob Hill Water Association The only significant area outside the City limits served by the City's water system is the unincorporated community of Gleed Direct Connection and Satellite/Remote Systems Section 12 04 010 of the Yakima Municipal Code requires that All new lots and development shall be served by a public water supply line maintained by the City of Yakima, Nob Hill Water Company, or other water purveyor, and located adjacent to the lot or development site. Yakima Municipal Code does not prohibit satellite water systems within the City limits or water service area The City has, however, elected not to become a satellite management agency Design and Performance Standards The water system minimum design and performance standards for new development have been developed by the City of Yakima Engineering Department. The standards are available to the public in a document titled WATER Specification and Details (1999) This document is available on the City's website https //www yakimawa pov/services/engineering/water/ Title 12 of the Yakima Municipal Code also establishes development standards for water service extensions. Copies Title 12 — Development Standards are also available from the City Engineering Department. Chapter 12.04 covers water system development standards. Section 12.04.030 requires that all water lines shall be looped. Section 12.04.040 requires that all new water lines within the City water service area shall be constructed of Class 52 ductile iron and shall be a minimum of eight inches in diameter, and that improvements and additions to the Nob Hill Water Company system shall conform to the requirements of Nob Hill Water Company (Ord. 98-64 § 1 (part), 1998). Surcharge for Outside Customers: The City imposes a surcharge of 1.5 x the volume rate for customers outside of the service area There is no surcharge on the connection fee. Due to the limitations of the water rights "place of use" boundary and agreements with adjacent purveyors, the circumstances in which the City might provide service to outside customers would be very limited. Urban Growth Area The City's service area and water rights "place of use" boundaries are entirely within and significantly smaller than the Urban Growth Area (except for the Gleed community which was included in the interim UGA, but not in the final UGA) Because of this the growth which occurs within the City's service area will be primarily through in -fill, and the need to proactively finance extensions in anticipation of growth is not expected to be necessary Cross -Connection Control Program Cross Connection control is covered in Chapter 7.68 of the Yakima Municipal Code under Article 7.68.070. The Water Division currently July 2017 1 1-27 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan has two full time Water Device Technicians who are dedicated to the inspection of cross connection control devices and enforcement of this ordinance Extension Water line extensions within the City water service area are governed by Chapter 12 04 020 of the Yakima Municipal Code which states that Water lines shall be extended to the point where the adjoining property owner's responsibility for further extension begins. This typically requires extension across the street or easement frontage of the developing property. In some cases it will require dedication of an easement and a line extension across the property or extension along two or more sides of the developing property. Extensions will be consistent with and implement the city's adopted water comprehensive plan (Ordinance. 98-64 § 1 (part), 1998). 1.9 Satellite Management Agencies The City of Yakima Water/Irrigation Division is not now and is not currently considering becoming a Department of Health approved Satellite Management Agency (SMA). The currently approved SMAs in the area are Nob Hill Water Association and Yakima County. It is the City's intent to refer any existing or proposed satellite systems within its service area boundaries to Nob Hill Water Association or Yakima County as the approved SMA. 1.10 Conditions of Service Municipal water suppliers have a duty to provide service to all new connections within their retail service area when the circumstances meet four threshold factors (RCW 43.20.260 Review of water system plan, requirements — Municipal water suppliers, retail service) 1 The municipal water supplier has sufficient capacity to serve water in a safe and reliable manner 2. The service request is consistent with adopted local plans and development regulations. 3 The municipal water supplier has sufficient water rights to provide service 4 The municipal water supplier can provide service in a timely and reasonable manner. For the City water system, a primary condition of service is that the customer be within the boundaries of the "place of use" area which is a condition of the City's surface water rights (see Figure 1-2) The other conditions of service are that the customer pays all applicable connection and user costs All water system extensions required to serve a customer must conform to the City design standards and developer standards 1.11 Complaints All water service related complaints are handled through the Water/Irrigation Division office which can be reached at (509) 576-6477. This number also serves as the Nights and Weekend Emergency telephone number to report problems and complaints after normal working hours. Water quality complaints are referred to the Water Quality Specialist at the WTP The Water Quality Specialist investigates the complaints and maintains records describing the nature of the complaint and the steps taken to resolve it All complaints are assigned a 1-28 1 July 2017 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan work order number which can then be tracked in the Cayenta Inc management system (Cayenta) Cayenta is a City wide program which tracks information about all of the City's facilities and equipment Additional information on Cayenta is included in Chapter 6 of this Water System Plan Update. All low pressure and other distribution system related complaints are referred to the Distribution Supervisor who investigates and takes corrective actions as necessary As with the water quality complaints, the distribution system related complaints are assigned a work order number and tracked in Cayenta July 2017 1 1-29 Chapter 1 — Description of Water System City of Yakima 2017 Water System Plan 1-30 1 July 2017 This page left intentionally blank 2 Basic Planning Data and Water Demand Forecasting This chapter presents an analysis of historical water use from 2011 to 2015, existing and future zoning and land use, and population projections in order to predict future water demands for the City of Yakima's water system 2.1 Current Population and Service Connections 2.1.1 Current Population The Washington State Office of Financial Management (OFM) official 2010 Census population figures and 2014 population estimates for Yakima County and the City of Yakima are listed in Table 2-1 Table 2-1. Current Population for the City of Yakima and Yakima County n icipality 2010 Census Population 2014 OFM Estimate Unincorporated =1"83,7551= Incorporated Total Yakima County 159,476 243,231 163,390 248,800 City of Yakima alone' 91,196 93,080 1. The City of Yakima population is included as a subset of the Yakima County Incorporated population. As discussed in Section 1.5, Existing Service Area Characteristics, the City of Yakima water system does serve some small areas outside the current municipal boundaries (including Gleed and a small portion of Union Gap) However, it does not serve significant areas in the western portions of the City of Yakima which are within the city limits, but served by the Nob Hill Water Association The net result is that the actual population served by the City's water system is significantly less than the OFM population figures in Table 2-1 The current population within the City's water service area was estimated using the City's geographical information system (GIS) and the 2010 Census population data for each Census block within the city limits. By overlaying the water service area boundaries with the Census block boundaries, GIS was used to calculate the population within the service area, as well as the population within the individual pressure zones. Where the service area lines cut through a Census block the amount of population assigned to each area or zone was interpolated based on the relative areas of the resulting Census block segments. Table 2-2 presents the resulting populations for individual pressure zones and the total water service area The 2015 population estimates were calculated by extrapolating the 2010 Census data using the OFM's estimated annual growth rate for the City of Yakima between 2010 and 2014 (0 51 percent) July 2017 1 2-1 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan Table 2-2.

Figure 1-1 shows total annual metered water use for the four major user classifications. Figure 2-2 shows the average monthly water use from 2011 to 2015 for the four major user classifications. This figure illustrates seasonal water use patterns and shows that water use is generally highest from July to October. By comparing the water consumption data in Table 2-5 to the water supply data in Table 2-4 it is possible to estimate the amount of water which is either non -revenue producing (fire, flushing mains, etc) or unaccounted for water (leaks, under reporting meters, etc) Table 2-6 summarizes the authorized non -revenue and unaccounted for water use ((i e distribution system leakage (DSL)) July 2017 1 2-3 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan Table 2-5.

The DSL estimates shown in this table vary somewhat from the DSL estimates documented in the City's Water Use Efficiency Reports This discrepancy is likely due to "Other Estimated Water Uses" being underestimated in the Water Use Efficiency Reports In order to estimate the total usage by each customer class it is necessary to add an appropriate percentage of the unaccounted for water into the metered usage for that customer class A proportionate fraction of the estimated unaccounted for water amounts for each year (as shown in Table 2-6) were added to the usage by each customer class to result in the adjusted use by customer class estimates presented in Table 2-7. For example, the adjusted single family residential use for 2011 includes 16 percent of the unaccounted for water estimate corresponding to that year since the single family use in that year was 16 percent of the total metered use. 2-6 1 July 2017 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan Table 2-7.

It only differentiates the water use by customer class. The City has recently installed new automated meter reading system software that will allow the City to incorporate water use location into the City's billing system in the future. To further analyze the water use patterns, the distribution of land for each zoning code classification was determined for each pressure zone using GIS to overlay the zoning code areas and pressure zones. Where the zoning areas cut through pressure zones, the amount of land area assigned to each pressure zone and/or zoning code was interpolated based on the relative areas of the resulting segments. Table 2-8 summarizes the land areas for each customer class and pressure zone. The land use zoning code classifications in Table 2-8 are grouped to correspond to the billing code classifications Single Family Residential, Multi Family Residential, Commercial, and Industrial Table 2-9 summarizes the distribution of land area among pressure zones Table 2-8.

This analysis of land use zoning distribution does not include the area served by the City's water system that is outside the City limits since this area is not within the City's GIS zoning coverage. The total area served by the City's water system that is outside the City limits is relatively small with respect to the total water service area (i.e. only 3% of the total water service area).

Percent of the total area of the listed zoning code classification which lies within the respective pressure zone level. Table 2-10 summarizes the water use for each customer class by pressure zone. The water use for the single family, multi -family, commercial, and industrial customer classifications were estimated based on the proportion of land area for each customer class within each pressure zones For example, the single family water use in the Level 1 pressure zone was determined by multiplying the total single family water use (Table 2-7, billing codes W11 plus W21) by the percent of land area designated as single family in the Level 1 pressure zone (Table 2-9) Land uses (residential, commercial, industrial) differ by pressure zone. For example, the Level 1 pressure zone includes a variety of municipal land uses, while the Level 3 pressures zone includes predominately single family residential. Due to the general distribution of land use types, it is assumed that 75 percent of interdepartmental water use is in the Level 1 pressure zone, 25 percent of interdepartmental water use is in the Level 2 pressure zone, and no interdepartmental water use is in the Level 3 pressure zone.

The largest customer, Jewell Apple LTD., accounts for less than 1.5 percent of total water consumption. Overall, water demand for the largest customers is relatively small compared to total consumption. Therefore, it was determined that additional analysis specific to these large customers was not necessary. July 2017 1 2-11 Chapter 2 - Planning and Demand Forecast City of Yakima 2017 Water System Plan 2.2.3 Equivalent Residential Units The demand of each customer class can be expressed in terms of equivalent residential units (ERU) for demand forecasting and planning purposes. One ERU is defined as the quantity of water used by one typical, full-time, single-family residential account. This was calculated based on the total residential volume sold (Table 2-10) divided by total residential accounts (Table 2-3). Table 2-12 summarizes the water use per single family connection Water system connection data was only available for 2015 As such, the ERU value was estimated based on 2015 water use and connection data Table 2-12. Water Use per ERU Estimate (2015) Total Single -Family Water Use (gallons)1 Total Single -Family Connections Gallons per Day (gpd) per ERU 1, 264, 700, 000 14,862 233 1 Water use includes water use inside and outside Yakima City Limits and non -revenue water consumption The quantity of water used by other customer class connections can be expressed in terms of ERUs. Table 2-13 summarizes the water use expressed in ERUs for each customer class. The 2015 average day demand (ADD) was calculated based on the total usage (Table 2-10) and number of connections (i.e. accounts) (Table 2-3) for each customer class. The number of ERUs per account was then calculated by dividing the 2015 ADD by the single-family residential ERU value (233). Table 2-13.

Projected Land Use, Future Population, and Water Demand 2.3.1 Projected Land Use Figure 2-3 shows the City's Current Zoning Map specific to the City's water service area This map was used to estimate the distribution of customer classifications within the water service area (described in Section 2 2 2) The Current Zoning Map serves as the basis for the City's land use project permit decisions The City's Current Zoning Map can only be modified through the public hearing process. Changes to the Current Zoning Map will include an evaluation process with criteria 2-12 1 July 2017 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan established to determine when and if rezoning of land will be necessary. The evaluation criteria includes: existing residential densities; water/sewer availability; street capacity; neighborhood characteristics; vacant land; and existing institutions (schools, hospitals, etc.). The Future Land Use Map (Figure 2-4) shows the proposed general distribution and general location of various land uses anticipated during the next twenty year planning period Figure 2-4 is a generalized proposal for where development is expected to occur within the water service area. Future land use designations serve as a guide for development and land use planning. The City does not anticipate expanding water service outside the existing water service area boundaries, since adjacent purveyors already serve the areas surrounding the City's water service area (as described in Section 1 5 1) It is anticipated that residential, commercial, and industrial growth will occur within the water service area primarily through infill on vacant land and increases in population density Within the City's water service area there are several sites that may be redeveloped with higher density uses in the next 20 years These include the Boise Cascade Company Mill and the Yakima Speedway There may be more than one appropriate zoning category within any future land use designation to suit a particular proposal. If the Future Land Use Map supports a proposed development, but current zoning does not relate to the proposal, then the City may consider rezoning The Future Land Use Map identifies the land use preferences of the community as a result of citizen participation. Table 2-14 summarizes the inventory and composition of the future land use designations included in Figure 2-4. A community preference for low and medium density housing is evident. A variety of commercial and industrial development opportunities are also identified within the City's water service area, consistent with the past development patterns of the community and the future needs of a growing and changing community.

These include the following: Low Density Residential - Primarily single family, detached residences Net residential density before considering roads and right of ways is less than 7 0 dwelling units per acre, which is considered the lowest residential density to efficiently support public services. Medium Density Residential - Characterized by a mixture of single family detached residences and duplexes, with a variety of other housing types at a residential density ranging between 7 0 and 11 0 dwelling units per acre High Density Residential - Apartments and densely developed planned residential developments ranging from 12 and above dwelling units per acre. A limited range of other land uses may be permitted, such as some professional offices and community services. An adequate and affordable supply of housing for all income levels within the community is a mayor goal of the Yakima Urban Area Comprehensive Plan To accomplish this goal, opportunities must be available for new development, but must also be balanced by the preservation of existing neighborhoods and the need to infill or redevelop some areas. As noted previously, infill will be a major factor with respect to growth occurring within the City's water service area. Commercial Land Use The Future Land Use Map includes six categories of commercial uses, which vary intensity by function and location Professional Office - Includes financial institutions, real estate, insurance, engineer, legal, medical offices and other similar business uses. Neighborhood Commercial - Small scale shopping centers, with shared parking and access, usually located on arterial streets. Neighborhood commercial centers are dispersed throughout the Urban Service Area to provide convenience shopping to the residential population Regional Commercial - Includes a mix of retail, service and business establishments on a medium to large scale. Commercial firms span a wide range of activities such as retail stores, business and professional services, hotel/motel operations, restaurants, theaters and gas stations. These firms are generally dependent upon visibility for customer attraction, and prefer locations with heavy traffic flows. Large Convenience Center - Provides areas for commercial activities to meet retail shopping and service needs of the community and accommodates clusters of retail, financial, professional service business and entertainment activities that attract shoppers from an area significantly larger than a neighborhood Regional centers may be considered appropriate when they demonstrate that they will complement, and not have a detrimental impact on existing commercial areas or surrounding land uses. Arterial Commercial - Land uses which require high auto visibility such as restaurants, service stations, car washes, as well as wholesale and retail activities Central Business District (CBD) Core Commercial - The City of Yakima downtown area is the regional center for commerce, cultural and governmental land uses. This area provides for a wide variety of intense retail, office, institutional, and high density residential land uses. 2-16 1 July 2017 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan Industrial Development Patterns The Future Land Use Map includes industrial uses Most of the land designated for industrial land use lies within the City's water service area Industrial - Mixture of land uses which provide a range of activities, including construction businesses, manufacturing, transportation, communication, utilities, and wholesale and warehouse activities, which may include some accessory office and retail use Industrial development is concentrated along Interstate 82, Fruitvale Boulevard, North 6th Avenue and the Burlington Northern Railroad tracks, making for convenient transportation of products. The Boise Cascade plant and storage area, highly visible from the Interstate 82 system has been located at that site since the turn of the century. The Airport region continues to provide industrial opportunities for warehouse and Tight industrial activities. Another unusual feature of the Yakima Urban Service Area is the amount of land which surrounds the railroad corridor The railroad corridor creates a large linear pattern which bisects the entire city and limits access to adjoining land uses Due to this fact, is difficult to maximize the development potential of much of the vacant land near the railroad corridor 2.3.2 Projected Population RCW 43 62 35 directs the OFM to prepare 20 year Growth Management Act (GMA) planning projections every five years Each county's GMA projection is expressed as a range within a reasonable "High" & "Low" projection Counties select a GMA planning population within the range released by OFM This provides counties with reasonable discretion in determining a GMA planning target. It is the responsibility of county and city governments in each county to allocate the projected planning population to the cities and unincorporated area in their county. As described in Sections 1 4 1 and 1 4 3 of this water system plan, Yakima County and the City of Yakima are currently updating the County and City Comprehensive Plans, respectively, which should be available by 2017 For the County and City Comprehensive Plans, Yakima County and the City of Yakima decided on a planning horizon out to the year 2040. Though this time frame extends slightly beyond the GMA mandated twenty -years, the year 2040 corresponds to the Federal decennial Census date and the time frame used by the OFM for their county -wide population projections. State law requires Yakima County to use a population projection from the range developed by OFM (low, medium or high). Based on an evaluation of OFM population estimates and recent Census results, the County determined that the medium OFM projection was the most appropriate for planning purposes This projection was also adopted by the City of Yakima As such, the medium projection was also applied to the demand forecast in this water system plan Table 2-15 presents the population projection selected by the City of Yakima for the Yakima Urban Area Comprehensive Plan update. This table also shows the projected annual growth rates for the City of Yakima. July 2017 1 2-17 Chapter 2 — Planning and Demand Forecast City of Yakima 2017 Water System Plan Table 2-15.

Source: Yakima County, Public Services Department 2 The population growth rate within the City's water service area is assumed to be half of the growth rate for the full City This is because there are limited infill and redevelopment opportunities within the City's water service area Population growth in the City is expected to be primarily within the western portion of the City, which is served by Nob Hill Water Association. As discussed in Section 2.1, the population of the City of Yakima water service area was estimated using GIS to overlay the water service area boundaries with the 2010 Census block boundaries and population data. The population within the entire service area, as well as the populations within the individual pressure zones, was estimated in this manner. For the purpose of this water system plan, the population data developed from the 2010 Census was extrapolated to 2015 using the OFM's annual population growth rate estimate for the City of Yakima between 2010 and 2014 (0.51 percent). To estimate future population growth, Yakima County used OFM's twenty-year medium annual growth rate, which has a steady annual decline Yakima County adjusted this future growth rate to estimate the growth within individual cities. The future growth rate developed for the City of Yakima provided the basis for estimating growth within the City's water service area (Table 2-15). As noted in Section 2.1.1, the City's water service area includes only a portion of the City. The water service area is expected to experience a slower growth rate than other parts of the City because there are limited opportunities for infill or redevelopment within this area Therefore, the population growth rate within the City's water service area is assumed to be half of the growth rate expected City-wide (Table 2-15) This slower population growth rate was applied to all customer classifications (single-family, multi -family, commercial, and industrial) Table 2-16 summarizes the population projections for each pressure zone and the total water service area in five-year increments. The total population for the water service area in 2027 (ten-year planning period) is projected to be 75,852. The total population for the water service area in 2037 (twenty-year planning period) is projected to be 78,159 Table 2-16.

The growth rate for interdepartmental water use was assumed to be zero. Interdepartmental water use is primarily associated with irrigation of parks and public areas. Because there are limited opportunities for infill and redevelopment in the water service area, the City does not anticipate development of any new parks or irrigated lands within this area. In addition, the City would likely use the City's non -potable water irrigation system to serve any large, new outdoor water uses that may be developed. ADD estimates for 2015 were calculated based on the total consumption (Table 2-10) Table 2-17 summarizes the ADD projections by customer class for each pressure zone and the total water service area. The total water service area ADD in 2027 and 2037 is projected to be 10.9 and 11.3 MGD, respectively. Figure 2-5 and Figure 2-6 graphically show the forecasted ADD by pressure zone and customer class, respectively Table 2-18 summarizes the projected water use in terms of ERUs for each customer class. The total ERUs for the water service area in 2027 and 2037 are projected to be 46,950 and 48,285, respectively.

Determination of the MDD is critical for the system analysis to evaluate the maximum demand on the water system, such as supply capability, pump station discharge rates, and pump sizes. MDD is determined by the maximum daily water production at the City's WTP and wells. Table 2-19 summarizes the historic MDD for each year from 2000 through 2014. Also shown in this table are the ADDs for each year and the ratio of the MDD to ADD. Table 2-19.

The description of the general condition of system facilities includes a summary of the physical condition of the facility as well as the facility's anticipated remaining life expectancy. The overall system analysis also includes a comparison of the existing facility capacity with the existing and projected water demands identified in Chapter 2 and in Section 3.1.5. The objective of the system description and analysis presented in this chapter is the identification of the extent and timing of any individual facility and/or functional group deficiencies Deficiencies identified in the first 10 years of the planning period are addressed and remedied by a specific project or action, according to a project schedule Deficiencies identified in years 10 through 20 are, in most cases, placed in the capital improvement program without identifying a specific schedule for implementation. 3.1 Description of Water System This section provides a description of the components of the City of Yakima water system including distribution, the Naches River Water Treatment Plant (VVTP), groundwater wells, and storage reservoirs The water system is divided into three pressure zones, further described in Section 3.1.1. The current supply sources for the water system consist of a surface water treatment plant on the Naches River and four groundwater wells. 3.1.1 Distribution System General Description and Condition A map of the City of Yakima water distribution system piping is shown in Figure 3-1 A summary of the pipe diameters and the respective lengths of each diameter in the system are shown in Table 3-1. The majority of the pipe material in the system is either ductile iron or cast iron (about 50% of each). There is about 5,280 feet of asbestos cement (AC) pipe in the distribution system, representing less than 0.5% of all piping. All new water mains are constructed using ductile iron pipe in accordance with the City standards (refer to Chapter 7 of this plan for additional information regarding construction standards).

The City of Yakima water system has three major pressure zones, designated as the 1St Level, 2nd Level, and 3rd Level zones, plus a separate pressure zone for Gleed, a small census -designated area between the WTP and the City which includes less than 30 service connections consisting primarily of single-family residential, a fruit warehouse, and the Naches Valley Primary School (the school will be decommissioned in 2017) A water system hydraulic profile schematic is shown in Figure 3-2 The relationship between the pressure zones is discussed below 1st Level Pressure Zone The gravity supply from the 48 -inch diameter transmission main flows to the 1st Level Reservoir, a 6 -MG reservoir located at North 40th Avenue and Englewood Avenue This reservoir supplies water to the 1st Level zone Flows from the WTP are manually adjusted to maintain a nominal hydraulic elevation of 1,264 feet, resulting in a static pressure range in the 1st Level zone of approximately 54 to 110 psi 3-2 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan The flow adjustments at the WTP are based on a judgment call by each shift operator. During the day shift in summer months, an operator may determine early in the day that an increase in treated water flow is required due to forecasting of high temperatures. An additional adjustment may take place later in the day depending on the observed water use. During the summer months, night shift operators will tend to raise flow in the evening too (as late as midnight) in anticipation of domestic water irrigation activities that generally start between 1 am to 3 am In the course of day shift and night shift, during the winter months, shift operators will make effluent flow adjustments primarily due to drop in level at the 1st Level Reservoir and the amount of water being pumped to the 2nd Level. The 1st Level pressure zone can also be served from the four groundwater wells which are used seasonally to augment the WTP supply During fire flow events or short-term pressure drops within the zone, the 1st Level pressure zone can be served by nine pressure reducing valve stations that allow water to flow from the 2nd Level pressure zone and by an intertie with the Nob Hill Water Association. 2nd Level Pressure Zone The 2nd Level pressure zone is served by the 2nd Level Reservoirs, two 12 -MG reservoirs located on City Reservoir Road. The Stone Church and 40th Avenue Pump Stations pump water from the 1st Level zone to the 2nd Level Reservoirs Pump station operation is controlled based on the water surface elevation within the 2nd Level Reservoirs The nominal hydraulic elevation is 1,380 feet, which results in a static pressure range of 43 to 105 psi During fire flow events or short-term pressure drops within the zone, the 2nd Level pressure zone can be supplied by three pressure reducing valve stations that allow water to flow from the 3rd Level pressure zone. From 2006 to 2009, improvements were made to the 2nd Level zone by replacing the existing steel transmission main that filled the reservoirs with ductile iron pipe Improvements also included installation of fill lines to the two 12 -MG reservoirs separate from the discharge lines; providing for improved mixing and water quality within the reservoirs; replacement of all transmission valves associated with the isolation of the reservoirs, replacement of the access ladders and overflow standpipes within the reservoirs, and installation of intrusion alarms on the reservoir access hatches 3rd Level Pressure Zone The 3rd Level pressure zone is served by the 3rd Level Reservoirs, two 1 -MG reservoirs located off of Scenic Drive The 3rd Level Pump Station located at the site of the 2nd Level Reservoirs pumps water from the 2nd Level zone to the 3rd Level Reservoirs The pump station operation is controlled by the water surface elevation within the 3rd Level Reservoirs The nominal hydraulic elevation is 1,531 feet, resulting in a static pressure range of 70 to 115 psi During emergencies, the 3rd Level zone can be supplemented by operating one pressure reducing valve station (a two-way valve station) that controls the intertie from the Nob Hill Water Association.

When the new advanced metering infrastructure (AMI) program is fully implemented, distribution system losses will be reevaluated and, if necessary, additional leak detection surveys will be conducted. Funding for these surveys has been programed into the utility rate model. Distribution system mapping is included in the City's Geographic Information System (GIS) This system enables Water Division personnel to continually update the map to record changes The GIS mapping also facilitates recordkeeping for tracking the age and condition of the distribution system pipe segments In 2013, the City also implemented a Cayenta maintenance management system This program includes information about all of the City's facilities and equipment This system replaced an aging system that was no longer supported Refer to Chapter 6 for more complete information regarding the Cayenta system. 3.1.2 Water Treatment Plant Background and General Information The WTP was constructed at Rowe Hill between 1967 and 1970, with a design capacity of 25 MGD, to replace the Oak Flats supply. The nominal capacity was maintained at 25 MGD after filter upgrades in 1991 in which a filter performance study was conducted. Treated water from the plant flows over a weir into a 48 -inch transmission main and to the City by gravity The condition and performance characteristics of the WTP plant along with recommended capital improvements are described in detail in Section 3.4. The existing WTP is rated at 21.6 MGD (14,976 gpm) in normal water supply years with the potential to possibly increase capacity pending a filter flow study. However, during 2001 due to drought conditions, the USBR reduced water available from USBR contract water to 29 percent This was one of the most severe reductions in water availability since the Naches WTP was placed into service and is therefore assumed to be a worst case scenario for the purpose of this source capacity analysis Additional reductions were seen in 2005 (42%) and 2015 (44%) Since original construction, the City has made process renovations to the plant from 1991 through 2014 as described below. In 1991, the four filters were rehabilitated Components of that project were as follows • Drilled out plugged orifices in the Leopold block underdrains • Replaced gravel support layers • Replace original filter media with new multi -media design. As part of the filter rehabilitation project, the State of Washington maintained the rated capacity of the WTP at 25 MGD based on results of a concurrent pilot filter demonstration study 3-6 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan In 1993, a new supervisory control and data acquisition (SCADA) system was installed, and it included the following items: • Continuous individual filter monitoring. • Greater capacity to gather water quality data. • Change in flow control to reduce influent flow rate during a filter backwash cycle to prevent a sudden flow increase to the remaining filters in service In 1997, the City completed installation of a bulk soda ash storage and feed system. This was in response to exceeding the copper action level of 1.3 mg/L in 1993. To achieve compliance with Lead and Copper Rule guidelines, the soda ash feed system is used to increase filtered water pH to 7.4. A 1998 report by Carollo Engineers titled Evaluation of the Naches River Water Treatment Plant (Carollo Engineers, August 1998) provided an assessment of the existing treatment plant components. This report identified deficiencies and recommended improvements to the WTP as needed to meet current and anticipated performance requirements. Many of the recommendations in this report were implemented in projects that were implemented in 2003, 2004, and 2005. A new fluoridation facility was constructed in 2001 and placed into service during the spring of 2002 The facility included a new building containing hydrofluosilicic acid storage tanks and chemical feed equipment The fluoridation equipment also included fluoride monitoring instrumentation and a containment tank to prevent the release of hydrofluosilicic acid in the event of an accidental spill In 2003, a major upgrade to the raw water intake facility was completed. The improvements included the installation of a flat panel screen with continuous backwash and a continuous air curtain to mitigate the build-up of ice in winter months In 2004, the then existing rapid mix coagulation system was replaced with a new pump diffusion mix system. The new flash mix/coagulation system, together with related piping modifications, enabled the WTP to achieve compliance with the Filter Backwash Recycling Rule which went into effect on June 8, 2004. In 2004, the existing gas chlorination system was replaced with an on-site sodium hypochlorite generator system. Chlorine is used for both primary disinfection (CT compliance) and as a secondary disinfectant (distribution system residual). Chlorine is added upstream of the contact basins (prechlorination) and downstream of the filters (post chlorination). The primary deficiency with the gas chlorination system was related to safety due to the lack of a chlorine scrubber system. The hypochlorite system had been recommended in the 1998 and 2004 planning documents as the preferred alternative to adding a scrubber and the other safety equipment which would be required if a gas chlorination system were to be maintained The on-site sodium hypochlorite generator system was installed in a new Chemical Handling Building. The chemical storage and handling facilities for aluminum chlorohydrate, alum, and filter aid polymer, were also relocated to the new building in the 2004 project. The new building included spill containment for all of the bulk chemical storage facilities, and corrected the other chemical handling facilities deficiencies which had been identified in the above -referenced planning documents. In 2005, a major upgrade to the filters was completed to address the deficiencies which were identified in the 1998 Carollo report and in the 2004 Water System Plan Update The filter upgrade included: replacing the clay block underdrains with an IMS type underdrain and the elimination of the gravel support system; replacing the multimedia filter media configuration with a dual media design; and modifications to the surface wash system. As part of this upgrade, the maximum filtration rate decreased from the July 2017 1 3-7 Diameter in 54 Tength (approximate) 1 4,000 Velocity @ 25 MGD EN 21 Contact Time @ 25 MGD Criteria Chapter 3 — System Analysis City of Yakima 2017 Water System Plan previously used 7 gpm/ft2 to 6 gpm/ft2, consistent with the filtration operation criteria of WAC 246-290-654. The reduced maximum filtration rate reduced the WTP capacity back to 21.6 MGD. If the WTP capacity needs to increase, a flow study could be performed to determine the media's capability of providing consistent 2 -log removal of Giardia lamblia cysts and Cryptosporidium oocysts The 2005 filter system upgrade also included the recommended upgrades to the filter -to - waste facilities, thereby correcting the deficiencies which had also been identified in the 1998 report and the 2004 WSP Update. In 2014, improvements were made for residual solids handling by constructing four new common wall concrete settling basins of 500,000 gallons each for a total settling basin volume of 2 MG The new settling basins provide adequate settling time for particles in the filter backwash stream A new pump station was also added to recycle the settled backwash and filter -to -waste water back to the WTP influent The improvements also Included a new auxiliary power generator, new electrical service, and upgrades to the SCADA system The design criteria for existing WTP unit processes are shown in Table 3-2.

The design of sources for the City is based on facilities operating at full capacity for 24 hours per day to meet the maximum day demand. 3.2.2 Storage The design of storage requirements must consider each of the five storage components listed below (reference WAC 246-290-235(3)): 1 Operational storage (OS), 2. Equalizing storage (ES); 3 Standby storage (SB), 4. Fire suppression storage (FSS); and 5 Dead storage (DS), if any These required volume components are illustrated in Figure 3-6. All storage components are described in more detail below. Figure 3-6. Storage Components OVERFLOW ELEVATION "EFFECTIVE" STORAGE VOLUME OPERATING VARIES EQUALIZING FIRE FLOW VARIES SOURCE OFF SOURCE ON STANDBY DEAD STORAGE 20 PSI (46') J 30 Psi (69') 8 8 HIGHEST SERVICE IN PRESSURE ZONE Operational Storage (OS) Operational storage is the volume of water that lies between low and high water storage elevations set by City operations staff to control system pumps and flow control valves Operational storage does not apply to systems operating under a continuous pumping mode or a gravity fed supply such as from the WTP 3-18 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Equalizing Storage (ES) Equalizing storage is the total volume needed to moderate daily fluctuations in diurnal demands during periods when the demand exceeds the capacity of the supply system Equalizing volume requirements are greatest on the day of maximum demand Operation of a properly balanced system results in replenishment of storage facilities during times of day when the demand curve is below the capacity of the supply system and depletion of storage facilities when the demand exceeds the supply capacity. The equalizing volume of a storage reservoir must be located at an elevation that provides a minimum pressure of 30 pounds per square inch (psi) to all customers served by the reservoir. Standby Storage (SB) Standby storage is required to supply reasonable system demands during a foreseeable system emergency or outage A key concept is that establishing standby storage involves planning for reasonable system outages — those that can be expected to occur under normal operating conditions, such as a pipeline failure, power outage or valve failure Major system emergencies, such as those created by an earthquake, are intended to be covered by emergency system operations planning, since construction of sufficient reserve volume to accommodate sustained system demands under emergency conditions is not economically feasible. DOH has established guidelines for determining minimum required standby storage volume This component is calculated as the greater of two times the average day demand, less multi -source credit, or 200 gallons times the number of ERUs served by the storage facility The multi -source credit is applicable only for pressure zones that have multiple sources of supply, and allows the required standby storage volume in such instances to be reduced The credit assumes the largest source of supply is out of service, thus, it is calculated as the total source available to a particular pressure zone, or zone combination, less the capacity of the largest source No credit is allowed for zones having only one source of supply. For a pump station with multiple pumps operating in parallel, each pump can be considered a source. Fire Suppression Storage (FSS) The required fire suppression storage volume for a given pressure zone is calculated as the required fire flow multiplied by the required duration, as established by the local fire authority. Required fire flows and durations vary across the service area, as it includes multiple zoning designations. The fire suppression storage volume of a storage reservoir must be located at an elevation that provides a minimum pressure of 20 psi to all customers served by the reservoir DOH allows for the "nesting" of standby and fire flow storage, with the larger used for the storage volume For the purpose of this plan, the nesting of standby and fire flow storage is considered. A letter of approval for the nesting of these storage volumes from the local fire authority is provided in Appendix H. Dead storage (DS) Dead storage (effective only to provide adequate pressure) is the volume of stored water not available to all consumers at the minimum design pressure July 2017 1 3-19 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3.2.3 Distribution Refer to Chapter 7 of this plan for a discussion of the City of Yakima Development Standards and Water System Specifications and Details. These standards cover pipe and valve materials, valve and hydrant spacing, and water/sewer separation. Minimum System Pressure The minimum system pressure design standard which has been established by the City of Yakima provides that during peak -hour demands, the distribution system should provide a minimum service pressure of 30 psi to all customers Under fire -flow conditions, service pressures across the City should not drop below 20 psi These design standards are consistent with the DOH Design Manual requirements and the applicable portions of WAC 246-290-230 Minimum Pipe Size Title 12 of the Yakima Municipal Code establishes development standards for water service extensions Chapter 12 04 covers water system development standards Article 12 04 030 requires that all water lines shall be looped Article 12 04 040 requires that all new water lines within the City of Yakima water service area shall be a minimum of eight inches in diameter and be constructed of Class 52 ductile iron pipe Telemetry Systems The existing telemetry system provides for monitoring and control of booster pumps, reservoir levels, the water treatment plant, and each of the wells. Each telemetry location can communicate with the water treatment plant and with each of the other telemetry locations Each telemetry unit consists of a programmable logic controller (PLC) and a VHF radio transmitter which communicates via a digital packet burst protocol Any new telemetry points must be compatible with the existing system Backup Power Backup power is provided for the various components of the water system in accordance with the DOH Design Manual and applicable regulations Currently, full backup power is available at the WTP, Stone Church Pump Station, and 3rd Level Pump Station Valve and Hydrant Spacing Fire hydrant location and number requirements are stipulated in Article 10.10.070 of the Yakima Municipal Code The maximum distance between fire hydrants in single-family zones shall be 600 feet In all other areas, including areas of single-family zones impressed with public buildings, and/or schools, the maximum distance between fire hydrants shall be 400 feet With regard to valve spacing, each project is reviewed to determine valve spacing based on main isolation for minimal disruption in service. In addition, valves are required at each intersection. Other Requirements Section 12 04 030 of the Yakima Municipal Code requires that all water lines shall be looped Temporary dead-end lines may be permitted based on an agreement between the developer and the City with provisions for timely completion of looping. 3-20 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3.3 Water Quality Analysis This section provides a summary of the City's compliance with applicable water quality regulations and monitoring requirements 3.3.1 Water Quality StandardE Overview The quality of drinking water in the United States is regulated by the Environmental Protection Agency (EPA). The 1974 Safe Drinking Water Act (SDWA) and its 1986 and 1996 amendments established specific legislation for regulation of public water systems by federal and state governments. Under provisions of the SDWA, the EPA is allowed to delegate primary enforcement responsibility for water quality control to each state. In the State of Washington, the DOH is the agency responsible for implementing and enforcing the drinking water regulations For the State of Washington to maintain primacy (delegated authority to implement requirements) under the SDWA, the State must adopt drinking water regulations that are at least as stringent as the federal regulations In meeting these requirements, the State has published drinking water regulations that are contained in Chapter 246-290 of the Washington Administrative Code (WAC) which establishes monitoring requirements, maximum contaminant levels, and requirements for follow-up actions Minimum standards for water quality are often specified in terms of Maximum Contaminant Levels (MCLS) Pnmary MCLS are based on chronic and/or acute human health effects Secondary MCLS are based on factors other than health effects, such as the aesthetic quality of the water Maximum Contaminant Level Goals (MCLGs) are based on the level of a contaminant in drinking water below which there is no known or expected risk to health MCLGs allow for a margin of safety and are non - enforceable public health goals According to WAC 246-290, a Group A public water system is defined as serving 15 or more residential connections or 25 or more people per day for 60 or more days per year As a Group a public water system, the City is required to satisfy drinking water quality regulations and conform to monitoring and reporting requirements as described by WAC 246-290.

Annually, the City reviews its Water Quality Monitoring Schedule (WQMS), as issued by DOH, and communicates any issues, or asks for clarification, with the State. A copy of the 2016 WQMS is in Appendix I. The approaches to monitoring for various parameters are outlined below, along with a summary of any recent (last six years) monitoring violations Details regarding the City's water quality results are contained within DOH's Sentry database system, accessible online at DOH's website https //fortress wa gov/doh/eh/portal/odw/si/ July 2017 1 3-23 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Monitored Parameters ft I •JL _IL Nitrate levels are monitored for each source on an annual basis. Details of nitrate monitoring are contained in the Inorganic Monitoring Plan in Appendix J There have been no recent violations Inorganic Chemicals (IOCs) IOC levels are monitored for each source, with the WTP sampled annually and the wells sampled on a three year cycle As of 2016, the WQMS has waivers for completing a full IOC test panel for all sources However, the WQMS requires iron monitoring for the Airport Well Details of IOC monitoring are contained in the Inorganic Monitoring Plan in Appendix J There have been no recent violations Volatile Organic Chemicals (VOCs) VOC levels are monitored at the WTP on an annual basis while the wells have waivers Details of VOC monitoring are contained in the Organic Monitoring Plan in Appendix K There have been no recent violations Synthetic Organic Chemicals (SOCs) SOCs are a large group of contaminants that include pesticides, herbicides, and soil fumigants and are typically monitored at sources for the water system The City currently has a waiver for all sources to perform SOC monitoring Disinfection Byproducts (DBPs) DBPs, including total trihalomethanes (TTHMs) and haloacetic acids (HAA5) are a group of organic compounds that can be formed as a result of drinking water disinfection by oxidants such as chlorine, chlorine dioxide, and ozone. For drinking water quality, TTHMs and HAA5 are monitored on a quarterly basis with eight samples taken for each parameter per cycle Details of DBP monitoring are contained in the Stage 2 D/DBPR Monitoring Plan in Appendix L There have been no recent drinking water quality violations However, several sample locations have seen elevated levels of TTHMs approaching near the TTHM MCL of 80 tag/L Since 2012, monitoring locations L3PS, Z- 14, and Z-49 have had a number of samples that had TTHM concentrations above 75% of the MCL (60 tag/L) as seen in Figure 3-7 Although there have been no MCL violations, the City is monitoring TTHM trends to keep TTHMs below the MCL and taking actions to lower concentrations as necessary. 3-24 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Figure 3-7.

The permit requires TTHMs and HAA5 levels in water injected into the aquifer to be less than 50 percent of the MCL. Monitoring of injected water takes place at the recharge wells at the beginning of recharge, every 30 days during recharge, and at the end of recharge. Monitoring is also required during the storage of ASR water, and annually at downgradient monitoring wells. Details related to DBP monitoring for ASR operations are discussed in the City's ASR permit regarding reservoir application number R4-34552. Radionuclides Radionuclides for gross alpha and radium 228 are monitored on a six year cycle at the WTP and for the four ground water wells Details of radionuclide monitoring are contained in the Inorganic Monitoring Plan in Appendix J There have been no recent violations Lead and Copper Lead and copper levels are monitored at targeted homes throughout the distribution system that meet the criteria as prescribed in the Lead and Copper Rule. Samples from at least 30 sites are required on a three year cycle. Details of lead and copper monitoring are contained in the Inorganic Monitoring Plan in Appendix J. There have been no recent violations. Coliform Indicator organisms are often used to test for bacterial and other microbial contamination in drinking water Total coliform, fecal coliform, and E. Coli are typical indicator organisms. The absence of coliform bacteria generally assures the water purveyor that pathogenic bacteria are not present. Samples are collected monthly to cover each pressure zone, reservoir outfall, and source distribution area. A minimum of 80 samples are required each month. Details of coliform monitoring are contained in the Coliform Monitoring Plan in Appendix M. July 2017 1 3-25 Chapter 3 - System Analysis City of Yakima 2017 Water System Plan Coliform was present in four samples since the start of 2011, with those samples collected in May 2011, November 2012, July 2013, and March 2015 E. Coli was absent for all four samples. There were no other recent violations, as less than 5% of collected samples were positive for coliform for each month. Asbestos A small quantity of asbestos cement pipe is located within the distribution system. Because of this, asbestos sampling is required once every nine years at this location. Details of this are contained in the Inorganic Monitoring Plan in Appendix J. There have been no recent violations Continuous Monitoring Parameters Residual disinfectant in the distribution system is imparted through the use of on-site generated sodium hypochlorite at the WTP and calcium hypochlorite at the wells Free chlorine residual is continuously monitored via SCADA at all sources, the 3rd Level Pump Station, and the connection with the Gleed service area Additionally, grab samples for free chlorine residual are taken daily at three locations in the distribution system Fluoridation of the system occurs through the use of hydrofluorosilicic acid at the WTP and sodium fluoride at the Gardner Park Well. Fluoride residual is continuously monitored at two locations via SCADA. At the WTP, turbidity is continuously monitored at various points in the treatment process, while alkalinity and hardness are sampled weekly Details of the parameters with continuous monitoring are contained in the Continuous & Miscellaneous Monitoring Plan in Appendix N There have been no recent violations Certified Laboratories For water quality testing that is not performed by the City, the certified laboratories listed in Table 3-9 are used.

The reports must contain certain specific elements; but may also contain other information that the purveyor deems appropriate for public education. Some, but not all of the information that is required in the reports, include the source and type of the drinking water, type of treatment, contaminants that have been detected in the water, potential health effects of the contaminants, identification of the likely source of contamination, violations of monitoring and reporting, and variances or exemptions to the drinking water regulations The City is in compliance with the CCR Rule, with annual CCRs published as required. A copy of the latest CCR is located in Appendix O. 3.3.3 TTHM Reduction and ASR As part of the City's ASR permit, the quality of water being injected into the aquifer is required to have TTHM and HAA5 concentrations below 50 percent of their respective drinking water MCLS. While TTHM and HAA5 concentrations have consistently been below the drinking water MCLS, their concentrations have occasionally exceeded the 50% MCL level. The formation of DBPs such as TTHM and HAA5 are heavily influenced by the chlorine residual, presence of natural organic matter (NOM), and water age When any of these parameters are reduced, the formation of DBPs decreases. A number of potential treatment methods and operational strategies exist that can remove or reduce DBPs These are typically related to either the removal of DBP precursors (such as NOM), change in disinfection strategies, or direct removal of DBPs after they formed Treatment methods of reducing NOM include: • Enhanced coagulation • Granular activated carbon (GAC) • Nanofiltration • Biological filtration Alternate disinfection strategies to chlorination include the use of • Chloramines • Chlorine dioxide • Ozone • UV disinfection July 2017 1 3-27 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Treatment methods that can be used for the direct removal of DBPs include: • Biological filtration • Granular activated carbon (GAC) • Reverse osmosis (RO) • Aeration During the course of permitting for its ASR program, the City considered the options above in its AKART analysis. In addition to DBP reduction, the City is considering installation of online or real-time TOC monitoring. As a condition of its ASR permit, the City will complete an engineering technical memorandum that will describe and evaluate a range of treatment and monitoring options The City will include the preferred option in its capital improvement program for implementation The technical memorandum is planned for completion in the first half of 2017 3.3.4 Lead Appurtenances in Water System In 2015 and 2016, the City has conducted research into whether lead materials exist in the City -owned portions of the water system. Through this research, no lead piping is known to exist within the public water system However, in older portions of the system there is the potential for lead gooseneck connections A lead gooseneck is a short segment of pipe that was used in the past as a flexible fitting for connecting service lines to water mains The City is identifying through records all possible locations for lead goosenecks and actively replacing all that are found Research and removal of lead gooseneck connections is planned to be completed by the end of 2020 Lead sampling has not found any levels above the lead EPA MCL 3.3.5 Identified Improvements No water quality improvements are required to meet drinking water quality standards However, while not needed to correct any existing drinking water quality deficiencies, the following improvements are included as part of the City's on-going efforts to maintain and upgrade the quality of the system to meet current and future needs, as well as meet ASR program and permit requirements. Removal of Lead Appurtenances The City will continue its efforts to remove lead gooseneck connections as well as any other lead appurtenances in the water system as they are discovered This will be completed as part of water main replacement projects and programs identified in Section 3.7.4. TOC Monitoring and/or TTHM Treatment (WQ-1) As a condition of its ASR permit, the City will complete an engineering technical memorandum that will describe and evaluate a range of treatment and monitoring options TOC monitoring and/or TTHM treatment will be developed following the completion of the engineering technical memorandum 3-28 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan . 3.4 Water Treatment Plant Analysis 3.4.1 Existing Water Treatment Plant — Analysis and Discussion The WTP has contact basins upstream of the filters and it meets the EPA definition of "direct filtration" because it does not include a sedimentation step prior to filtration. This distinction is important because a "direct filtration" plant must provide a higher level of disinfection than a conventional water treatment plant. The applicability of direct filtration is generally limited to facilities which have high quality source water (< 15 NTU turbidity). Actual operating experience has shown that the plant can handle intermittent periods of higher raw water turbidity Sustained periods of high turbidity are rare When they do occur they are typically due to rain on snow flooding during the winter months or from spring snowmelt During periods when it is not feasible or not economical to treat the Naches River water, the WTP is shut down and the seasonal use wells are activated to meet demand until the raw water turbidity returns to treatable levels Existing Conditions Raw Water Intake The intake for the water system is located on the Naches River about 6 miles west of Yakima. Water is diverted from the Naches River approximately one quarter mile upstream from the WTP intake structure through three head gates. The intake structure has a number of fish protection facilities. Water leaves the intake and travels to the WTP through a 54 -inch diameter concrete main. The intake is located on the left bank of the river. However, river flow has shifted towards the right bank causing intake capacity issues. Contact Basins Two rectangular contact basins are located between the flash mix basin and the filters. Coagulated water must flow through them before it goes into the filters. No mechanical mixing or sludge removal equipment exists in the basins, and plant staff does not currently have the capability to add chemicals to the basins Disinfection Facilities Chlorine is used for both primary disinfection (CT compliance) and as a secondary disinfectant (distribution system residual). Chlorine is added upstream of the flash mix basins (pre -chlorination) and downstream of the filters (post chlorination). An on-site hypochlorite generation system was installed in 2004 to replace the gas chlorination system Residuals Handling Four new common wall concrete settling basins of 400,000 gallons each for a total settling basin volume of 1,600,000 gallons collect filter waste wash water streams and settled solids from the contact basins Decanted water is recycled back to the plant upstream of the flash mix basins The recycle rate is about 10 percent of the influent flow and is operated based on water level within the basins Settled sludge is removed out of the basins on an as -needed basis July 2017 1 3-29 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3.4.2 Identified Improvements No improvements are currently required to meet current or upcoming regulatory requirements. The following improvement is included as part of the City's on-going efforts to maintain and upgrade the quality of the system to meet current and future needs. Rechanneling River Intake (WT -1) The WTP's intake is located on the left bank of the Naches River However, the Naches River has experience significant changes in the location of the river's channel The channel has migrated away and has lowered in elevation to the intake causing intake capacity issues To alleviate the issues, the City plans on potentially doing a combination of (1) maintaining or adding to the existing grade control structure downstream of the main intake; (2) adding to the existing grade control structure at the auxiliary intake to encourage flows towards the intake; and (3) installing in -river structures upstream of the intake to redirect the river's channel toward the intake gates. Residual Handling Improvements (WT -2) Due to climate change and the changing turbidity conditions within the Naches River, the WTP has been handling an increased turbidity loading on the filtration process The higher turbidity levels observed in the last couple years before 2016, have caused an increase in the amount of solids sent to the filter backwash waste lagoons Future options for supplementing the residual handling process during fall and winter operations, when turbidity is typically at its highest, should be explored in order to accommodate the increased loading conditions in the treatment process. 3.5 Source Capacity Analysis The source capacity analysis examines the adequacy of the sources serving the water system to support current and projected future levels water demand According to DOH planning requirements, sources of supply must be sufficient to meet needs on a MDD basis. This must hold true for the system as a whole, as well as for each pressure zone that has storage. The source capacity analysis was broken into the following analyses • System Wide — Compares the demands of all pressure zones with the source capacity of the groundwater wells and WTP. • 2nd and 3rd Level pressure zones — Compares the demands of the 2nd and 3rd Level pressure zones with the source capacity of the 40th Avenue and Stone Church Pump Stations. • 3rd Level pressure zone — Compares the demands of the 3rd Level pressure zone with the source capacity of the 3rd Level Pump Station. 3-30 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3.5.1 System Wide Source Capacity The system wide source capacity analysis uses the demand for the entire system and compares this with the source capacity of the groundwater wells and WTP which provide water to the complete system. The system wide source capacity analysis considers three planning scenarios: • Non -Drought Year — This analysis assumes the WTP is able to deliver at its full rated capacity. The groundwater wells are not used as a source. • Drought Year — This analysis assumes the WTP capacity is reduced due to drought conditions similar to those experienced in 2001 All groundwater wells are able to be used as sources • Treatment Plant Offline — This analysis assumes the WTP must be taken completely offline All groundwater wells are able to be used as sources Demands remain the same between the three planning scenarios for each year (no additional conservation or curtailment of demands is assumed for the drought year or treatment plant offline scenarios). The source capacity analysis for the complete system for years 2017 through 3037 is presented in Table 3-10. As seen in the table, given a non -drought year scenario, the WTP is capable of meeting current and projected demands. In the drought -year scenario, the sources are capable of meeting current and projected demands; however, with the reduced capacity of the WTP, seasonal use wells will have to be activated. When using the existing inventory of groundwater wells in addition to the curtailed WTP supply, the total available source does exceed the full capacity of the WTP on its own. In the scenario of the WTP taken completely out of service, the existing sources of supply are not capable of meeting current nor projected maximum day demand without activating additional ASR wells. The City is actively pursuing the installation of new ASR wells to add to the City's source portfolio to remove this deficiency and have complete redundancy in the event the WTP must be taken entirely offline. Development of the new ASR wells is further discussed in Chapter 4. July 2017 1 3-31 Chapter 3 - System Analysis City of Yakima 2017 Water System Plan Table 3-10.

During 2001, due to extreme drought conditions, the USBR reduced the storage control capacity of the water treatment plant to 29% and is assumed as a worst case scenario for a drought given current climate conditions (10 cfs + 29% of 29 cfs). Due to climate change, more severe reductions are possible in the future. It is assumed the control capacity is reduced to 20% in 2027 and 15% in 2037. 8. Assumes the WTP is completely offline. 9. Well capacities differ from those provided in Chapter 1 and the Water Facilities Inventory (WFI) Form which are nominal capacities while the capacities provided in this table are based on current operating conditions which yields more conservative values 3.5.2 2nd and 3rd Level Pressure Zone Source Capacity The 2nd and 3rd Level pressure zone source capacity analysis compares the demands of the 2nd and 3rd Level pressure zones with the source capacity of the 40th Avenue and Stone Church Pump Stations, which both pump water from the 1st Level pressure zone into the 2nd Level Reservoirs Since water for the 3rd Level pressure zone originates from the 2nd Level pressure zone, these two pump stations are considered the sources for both zones Table 3-11. 2nd & 3rd Level Zone Source Capacity Analysis for Years 2017 through 3037 Year 2017 2027 2037 Max 1 Projected Equivalent Residential Units (ERUs) 2 9,413 9,738 10,020 34,256 Projected 2nd and 3rd Level Demand 3 Average Day (gpd) 2 19 2 27 2 33 7 98 Say (g.

Details of projected demands are in Chapter 2. 4 Assumes sources are operating at their maximum production rate (operating 24 hours per day) 3.5.4 Water Rights Analysis The City of Yakima holds a number of water rights that supply the City's domestic and municipal irrigation distribution systems. All of these water rights are described in Chapter 4 of this plan and in Table 4-5and Table 4-6 (see Section 4 3) The City holds several other water rights that are not considered in this source capacity analysis, because they are not part of the City's municipal water distribution systems and are not used for domestic purposes See Chapter 4 for the water right self-assessment 3-34 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3.5.5 Identified Improvements Additional Source Wells (S-1) The only deficiency found in the source analysis is for the scenario of the Naches WTP being taken out of service or having its capacity limited to under 4.7 mgd (3,264 gpm) which is the deficiency for current maximum day demand when the WTP is taken out of service. The City plans to develop additional well sources to remove this deficiency given this scenario. The sources could be designated for seasonal/emergency use. Development of additional ASR wells (as described in Chapter 4) would address the deficiency Stone Church Pump Station Improvements (S-2) The Stone Church Pump Station was installed in 2000 near the intersection of North 32nd Avenue and Englewood Avenue. This pump station system provides an alternative (to the 40th Avenue Pump Station) for supplying the 2nd Level zone, which bolsters reliability and the ability to satisfy emergency demands. The Stone Church Pump Station is equipped with three booster pumps with motors rated at 50 hp, 100 hp, and a 125 hp. This project would install a new Variable Frequency Drive (VFD) for the 125 hp pump and motor, along with required SCADA equipment and programming. This will provide for improved system operation for the 2nd Level zone should the 2nd Level Reservoirs and 40th Avenue Pump Station become isolated from the system due to a main break or other system failure 3.6 Storage Capacity Analysis The storage capacity analysis is based on an evaluation of the existing storage reservoirs and their ability to meet the demands of the areas in which they serve. This is based upon two primary calculations: 1 Comparison of available versus required storage located at an elevation that provides at least 30 psi to the highest customer in the zone This evaluates the ability of existing storage facilities to provide required operational and equalizing storage volumes under current and future conditions. 2. Comparison of available versus required storage located at an elevation that provides at least 20 psi to the highest customer in the zone. This evaluates the ability of existing storage facilities to provide required operational, equalizing, standby, and fire flow storage volumes under current and future conditions. For each pressure zone, the required volumes for operational, equalizing, standby, and fire suppression storage are calculated These storage volumes are based upon the demands of the individual pressure zone each reservoir directly serves In the analysis, if there is a surplus of storage that is available at 20 psi or more for a pressure zone, that storage is made available to the next lower pressure zone for use in meeting standby or fire suppression storage needs PRVs in the distribution system allow for movement of water from upper to lower zones under certain pressure conditions An illustration of this is shown in Figure 3-8. Because of this, the storage capacity analysis uses a top to bottom approach where the analysis starts with an evaluation of the highest pressure zone and ends with the lowest pressure zone. July 2017 1 3-35 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Figure 3-8.

The 3rd Level Reservoirs serve by gravity the demands of the 3rd Level pressure zone and are filled from the 2nd Level Pressure zone via the 3rd Level Pump Station. Being the highest zone, the analysis of fire suppression and standby storage volumes for the 3rd Level zone (which must be provided from elevations so as to provide a minimum of 20 psi to customers in this zone) considers storage only available in the 3rd Level Reservoirs. Table 3-13 provides a summary of the storage capacity evaluation for the 3rd Level Reservoirs. The evaluation found that the 3rd Level Reservoirs have no storage deficiencies during the forecast period for the area that it serves. However, this is based on a highest service elevation of 1,460 ft, the elevation that creates a net zero surplus/deficiency in storage required at 30 psi. At elevations higher than 1,460 ft in the 3rd Level pressure zone, water service to residences is provided by a combination of City water and Nob Hill Water Association Figure 3-9 shows the residences and hydrants served by the City and the 3rd Level pressure zone. As shown in Figure 3-9 one fire hydrant and seven single-family residences are located above the 1,460 ft elevation contour, with the hydrant at an elevation of 1,465 ft and the highest residence having a service connection at 1,490 ft. 3-36 1 July 2017 954,000 954,000 1,007 000111, 007, 000. 1,961,000 1,961,000 North 3rd Level Reservoir (gal) South 3rd Level Reservoir (gal) Total Existing Storage at 30 psi (ga Storage Surplus/(Deficiency) at 30 psi (gal) 9 ■ 53,000 53,000 100 0 53,000 53,000 106,000 0 53,000 53,000 106,000 0 125 HP Pump (gpm) Available Source (gpm) 1,700 1,700 1,700 Chapter 3 - System Analysis City of Yakima 2017 Water System Plan Table 3-13. 3rd Level Reservoir Storage Capacity Analysis for Years 2017 through 3037 Year 2017 2027 2037 Projected 3rd Level Equivalent Residential Units (ERUs) 1 2,121 2,201 2,270 Projected 3rd Level Demand 2 Average Day (mgd) Peak Hour Demand (mgd) �0 49 _u 87 1 42 051 0 90 1 47 0 53 0 93 1 51 Existing 3rd Level Sources 3rd Level Pump Station Required Storage Calculations Operational Storage (gal) 3 106,000 106,000 106,000 Equalizing Storage (gal) 4 Standby Storage (gal) 5 0 1011424,000 0 0 440,000 454,000 Fire Suppression Storage (gal) 6 960,000 960,000 960,000 Required Storage Greater than 30 psi at highest meter (gal)' 106,000 Greater than 20 psi at highest meter ( `1,066,000 106,000 1,066,000 106,000 1,066,000 Existing Storage Greater than 30 psi Existing Storage Greater than 20 psi North 3rd Level Reservoir (gal) WTI 3rd Level Reservoir (gal) Total Existing Storage at 20 psi (gal) 954,000 007, 000 1,961,000 (gal) 10 1 .95, 000 895,000 ,. 895,000 1 Notes: 1 ERUs calculated as average day demand / ERU water use factor (233 gpd/ERU) 2 Details of projected demands are in Chapter 2 3 Required operational storage based on storage reservoir levels of lowest pump call and highest pump release 4.

No recent complaints about low water pressure by these residences have been received. These low pressure service connections have been in existence for more than 20 years Given the low number of service connections located higher than 1,460 ft, the established operation of the system in the current configuration, and the high cost for increasing storage, the City does not have any plans to make improvements related to pressures for these few service connections. In this area above 1,460 ft, no new service connections to the City distribution system will be made unless a new pressure zone is created in this area. Any properties in this area requesting a new water service connection will be considered for potential service by the Nob Hill Water Association instead of the City system. 3.6.2 2nd Level Reservoirs Evaluation The 2nd Level Reservoirs evaluation examines the adequacy of the 2nd Level Reservoirs to meet the demands of the area they serve. The 2nd Level Reservoirs serve by gravity the demands of the 2nd Level pressure zone and are filled from the 1st Level pressure zone via the Stone Church and 40th Avenue Pump Station However, due to PRV connections, the surplus water stored in the higher 3rd Level Reservoirs is also available by gravity to meet emergency storage requirements in the 2nd Level pressure zone. Therefore, the analysis of fire suppression and standby storage volumes for the 2nd Level zone (which must be provided from elevations so as to provide a minimum of 20 psi to customers in this zone) considers the storage available in the 2nd Level Reservoirs and the surplus storage in the 3rd Level Reservoirs Table 3-14 provides a summary of the storage capacity evaluation for the 2nd Level Reservoirs.

Available to meet standby and fire suppression storage needs for the 1st Level Pressure zone. 1st Level Reservoir Evaluation The 1st Level Reservoir evaluation examines the adequacy of the 1st Level Reservoir to meet the demands of the area it serves. The 1st Level Reservoir serves by gravity the demands of the 1st Level pressure zone and are filled primarily from gravity flows from the WTP with supplemental flows from the seasonal groundwater wells, Gardner Park, Kissel Park, Airport, and Kiwanis Park As a conservative approach to including the seasonal wells, from the ground water wells, only the Gardner Park Well is included as a source However, due to PRV connections, the surplus water stored in the higher 2nd Level Reservoirs is also available by gravity to meet emergency storage requirements in the 1st Level pressure zone Therefore, the analysis of fire suppression and standby storage volumes for the 1st Level zone (which must be provided from elevations so as to provide a minimum of 20 psi to customers in this zone) considers storage available in the 1st Level Reservoir and the surplus storage in the 2nd Level Reservoirs, which in turn account for surplus storage in the 3rd Level Reservoirs as well The Gardner Park Well, which operates on a VFD, is manually operated on an as needed basis and is not automatically operated based on levels in the 1st Level Reservoir. The WTP provides a constant gravity flow which is manually increased or decreased depending on predicted near-term demand Because of these operating conditions, the storage analysis assumes zero operating storage for the reservoir Equalizing storage was estimated by running an extended period simulation (EPS) in the water system model using the maximum day demands and summer diurnal curve presented in Section 3 1 5 During the EPS run, the only source contributing water into the system was the WTP The flow from the WTP was adjusted until the storage levels in the 1st Level Reservoir reached an equilibrium (reservoir level did not have a losing or gaining pattern) across the EPS run The difference between reservoir level high and low points is then used as the equalizing storage Plots of this analysis for the forecast years are shown in Figure 3-10, Figure 3-11, and Figure 3-12 The figures show a slight increase in equalizing storage through the forecast period beginning with a current equalizing storage height of 3 3 ft and increasing to 3 4 ft and 3 5 ft in years 2027 and 2037, respectively These heights are then translated into volumes, considering the dimensions of the 1st Level Reservoir July 2017 1 3-41 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Figure 3-10. 2017 EPS Run for Determining Equalizing Storage 11 r 6- 0 1 w Cl M 1 1 A 4 A 4 NV 1 50 100 150 200 250 300 350 Model Run Time (hours) Figure 3-11. 2027 EPS Run for Determining Equalizing Storage 15 14 > 13 a) J L '5 12 a) u) 11 ce a) > 10 ti 9 i 1 1 0 50 100 150 200 250 Model Run Time (hours) 3-42 1 July 2017 300 350 Chapter 3 – System Analysis City of Yakima 2017 Water System Plan Figure 3-12. 2037 EPS Run for Determining Equalizing Storage 14 .-.13 w Tv J • 12 L_ w 11 co cv > 10 cvN 9 11 —BEIM —E—ESM 0 it 1 1 1 50 100 150 200 250 300 350 Model Run Time (hours) The modeled equalizing storage was validated by looking at the high and low levels in the 1st Level Reservoir as recorded by the City's SCADA system around the maximum day demand in 2015 and when the WTP was delivering a constant flow.

Storage surplus at 20 psi from Table 3 14. 3.6.4 Identified Improvements No improvements are currently identified for the storage reservoirs in the system 3.7 Distribution System Analysis The purpose of the hydraulic analysis is to evaluate the hydraulic capacity and operational behavior of the City's water distribution system and to determine how the supply, pumping, and storage components interact 3.7.1 Description of Analysis Hpproacn Computer Hydraulic Model As part of the development of the 1995 Water Comprehensive Plan, the City developed an EPANET water system model based on information from the City's GIS system In subsequent water system plans, the model has been continually updated to keep the model current with changes to the City's water infrastructure The City currently keeps the water system model in EPANET Version 2 0 and uses the model to perform static and dynamic hydraulic and water quality analyses For the conveyance system analysis for this Water System Plan Update, the City's existing EPANET model was exported into Bentley WaterCAD V8i Select Series 5 to complete the modeling work. After exporting to WaterCAD, the physical parameters of the model were checked and updated as needed This work included • Updating pump curves in the model • Updating PRV settings • Updating model node elevations to most recent contour data (2 -ft interval) available • Updating pump operational rules/controls After the physical parameters of the model were updated, demands were then allocated into the model Demand Allocation Demands are allocated to junction nodes in the model. Junctions are located at the intersections of pipe mains and, in some locations, between intersections. Junction nodes are not included for every service connection Thiessen polygons were created for the junctions in the model to determine the contributing area for each model junction. Some nodes in the model were excluded as they were either on transmission piping or nodes used to represent the reservoir, pump 3-46 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan station, and well components in the model and therefore do not include any demands. The Thiessen polygons were then overlaid with 2016 parcel land use data to determine the junction each parcel should be assigned to. Existing and forecasted demands were developed for each customer class for each pressure zone After subtracting the demand of the top 20 users from the associated customer class demand, the remaining customer class demand in each pressure zone was evenly distributed to each parcel related to that customer class. The demand of each of the top 20 users was then applied to specific junctions in the model that were near each user. For each pressure zone, a correction factor was globally applied to all the demand junctions within a pressure zone to make minor adjustments to make the pressure zone wide demands in the model match the demands developed in the demand forecast For EPS runs of the model, demand curves were added to junction demands based on the diurnal curve discussed in Section 3.1.5. Calibration A steady-state calibration of the model was completed using data collected from fourteen fire hydrant flow tests performed throughout the distribution system The static and residual pressures measured from the flow tests were then compared to the predicted values in the model. Calibration of the model was performed primarily by adjusting roughness factors for pipes. Table 3-16 summarizes the measured field data and predicted model values after performing the model calibration. Data on pipe materials and age were not readily available for the majority of the pipes in the system Instead of using an automated calibration process where pipes of similar materials and age are grouped together with a similar roughness factor, a manual calibration process was followed that grouped areas of the system together based on proximity to hydrant test locations with roughness factors adjusted There are no standard industry adopted criteria for calibrating a water system model. However, for a model used for general water system planning, general guidelines include keeping predicted hydraulic grade line results to within 10 feet (4.3 psi) of measured values and, in the case of hydrant flow testing, keeping the difference in the measured pressure drop to predicted pressure drop under 5 psi. After calibration, the model meets both these criteria in all hydrant test locations. After review of the data collected from the field and model, it was determined that any discrepancies between the field and model were within a reasonable margin of error and that the model was sufficiently calibrated to performed the required analysis July 2017 1 3-47 4102 Donald Dr 3rd Lvl 1,443 88 88 8 -0 8 70 68 8 1 2 18 20 0 2 0 Chapter 3 - System Analysis City of Yakima 2017 Water System Plan Table 3-16.

DOH also recommends keeping velocities under 8 ft/s during PHD conditions. A minimum of 20 psi must be maintained for fire flows under MDD conditions with operational, equalizing, and fire flow storage depleted A number of steady state hydraulic analyses were completed for each pressure zone for existing (2017), 10 -year (2027), and twenty-year (2037) demand conditions. These considered peak hour demand and fire flow demand (MDD plus fire flow) conditions. Table 3-17 describes the modeling scenarios conducted, and the sequence within which they were performed. The results of the peak hour and fire flow analyses are described in greater detail below. Table 3-17.

Incorporation of potential new ASR wells in the 2027 and 2037 model scenarios were not included. Modeling of these new sources will be conducted as plans for the ASR facilities develop. Table 3-18.

Under the peak hour condition, the water system was evaluated to identify any areas of the system that may have a pressure below 30 psi or pipes with a velocity exceeding 8 ft/s. Under the maximum day plus fire flow condition, the water system was evaluated for its ability to provide the required fire flow capacity while maintaining residual pressures above 20 psi within the pressure zone of the hydrant being analyzed. 3.7.2 Peak Hour Demand Analysis Results 2017 Peak Hour Demand When running the model for the existing (2017) peak hour demand, all service connections had pressures that exceeded 30 psi The only model nodes with pressures less than 30 psi were located near the 2nd and 3rd Level Reservoirs or on the 1St Level Reservoir transmission line Additionally, all pipes in the system have a velocity under 8 ft/s, with the exception of the Gardner Park Well discharge pipe When the well operates at full capacity (3,000 gpm) the velocity in its 20 foot long, 12 -inch discharge pipe is 8 5 ft/s There are a number of nodes at the lowest portions of the 3rd Level and 2nd Level pressure zones that have pressures that exceed 100 psi The City is not aware of any current high pressure issues or complaints in these areas Therefore, no modification of the pressure zones will be made to lower system pressures The results of the 2017 peak hour demand analysis is shown in Figure 3-14. 2027 Peak Hour Demand When running the model for the 10 -year (2027) peak hour demand, all service connections had pressures that exceeded 30 psi.

The maximum fire flow available is defined as the maximum flow that can be delivered to a fire flow node while keeping system pressures above 20 psi with operational, equalizing, and fire flow storage depleted. This is then compared to the required fire flow for the node to determine if there is a deficiency. As part of the 2011 Water System Plan, the required fire flow for a number of locations throughout the system were determined based on the land use and building types which presently exist in the vicinity of those locations as determined by the International Fire Code Appendix B, Table B105 1, Fire Flow Requirements for Buildings These locations, in addition to the largest fire flow demands per pressure zone (as used in Section 3.6) were entered into the model. A summary of these required fire flows at select nodes is given in Table 3-19. For the remaining fire flow nodes throughout the water system, general fire flow goals were applied based on the following • Surrounding zoning is single family residential = 1,000 gpm • Surrounding area includes zoning that is not single family residential = 1,500 gpm Table 3-19.

Figure 3-19 illustrates the available fire flow given current demand once the identified and planned improvements are made. 3-56 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 2027 Fire Flow Analysis The 2027 fire flow analysis incorporates the improvements identified in Table 3-20 as well as other system improvements currently planned by the City (see Section 3 7 4) The analysis also incorporates infrastructure related to the development of the former Boise Cascade Mill Site to determine requirements needed for fire flow. The area was modeled by placing a 12 -inch water main from the north end of N 10th Street to the east end of E Erikson Lane Looped distribution branches using 8 -inch pipe were added off of the new 12 -inch main Given this setup, ample fire flow is available for any type of development in the area (at least 7,200 gpm on the 12 -inch main and at least 4,200 gpm on 8 -inch looped mains) As shown in Table 3-20 and Figure 3-20, no additional nodes were found to be deficient from the 2017 fire flow analysis. For the 2027 fire flow analysis, all nodes previously found to be deficient in the 2017 fire flow analysis had the deficiency either fully addressed by an identified improvement or had little change in available fire flow. Because of this, no further improvements are identified based on the 2027 fire flow analysis. Figure 3-21 illustrates the available fire flow at nodes throughout the system given the incorporation of improvements with 2027 demand. 2037 Fire Flow Analysis The 2037 fire flow analysis utilizes the infrastructure used in the 2027 fire flow analysis with no other infrastructure added. As shown in Table 3-20 and Figure 3-22, no additional nodes were found to be deficient from the 2027 fire flow analysis For the 2037 fire flow analysis, all nodes previously found to be deficient in the 2027 fire flow analysis had the deficiency either fully addressed by an identified improvement or had little change in available fire flow Because of this, no further improvements are identified based on the 2037 fire flow analysis Figure 3-23 illustrates the available fire flow at nodes throughout the system given the incorporation of improvements with 2027 demand July 2017 1 3-57 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan 3-58 1 July 2017 This page left intentionally blank.

The existing PRV station in Snowmountain Road would be moved to be immediately west of North 42hd Avenue to maintain a connection between the 3rd and 2nd Level zones. July 2017 1 3-69 Chapter 3 - System Analysis City of Yakima 2017 Water System Plan The existing 8 -inch pipe in West Lincoln Avenue between North 42nd Avenue and North 40th Avenue (approximately 650 feet) and the existing 6 -inch pipe in North 42nd Avenue between West Lincoln Avenue and Uplands Way (approximately 330 feet) would both be replaced with 12 -inch pipe. The 3rd Level zone would be isolated at the intersection of Snowmountain Road and North 42nd Avenue via a PRV station and at North 42nd Avenue's intersections with Avalanche Avenue and Uplands Way via closed valves. Uplands Way and Avalanche Avenue would each have a short, block -long dead-end segment. Alternatively, a new 8 - inch DI pipe could connect Uplands Way and Avalanche Avenue to provide looping. Waterlines at the intersection of North 42nd Avenue and West Lincoln Avenue would be modified to separate the 3rd and 2nd Level zones while keeping looping of pipes. A new hydrant would also be placed mid -block on North 41st Avenue between Avalanche Avenue and West Lincoln Avenue These improvements would substantially increase available fire flow to the area. Available fire flow would go from 69 percent of the fire flow goal to 123 percent of the fire flow goal. Figure 3-24.

Through looping of the dead-end pipes, the improvements will increase fire flow to 106 percent of the fire flow goal. Figure 3-25. Peach Street Waterline Fire Flow Improvements July 2017 1 3-71 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan South 1st Avenue Waterline Fire Flow Improvements (D-3) At the south end of South 1st Street, an existing 8 -inch water main reaches a dead-end. The pipe serves an industrial area sandwiched between a Union Pacific Railroad right-of- way to the west and a Burlington Northern Railroad right-of-way to the east. The existing dead-end water line only has an available fire flow of 1,300 gpm at its end. The project would loop the existing main by connecting to the existing 8 -inch waterline in Division Street via a new 12 -inch DI pipe (approximately 600 feet). Looping would increase the available fire flow to over 4,200 gpm. Alternatively, the pipe could be looped by connecting to the existing 12 -inch waterline on South Front Street to the east Both options will require crossings within railroad right-of-ways An alternate approach would be to extend the waterline to the south using 1,450 feet of 12 -inch DI pipe to connect with the existing 8 -inch water line in Arlington Street This approach would increase the available fire flow to over 5,000 gpm Given the three possible routes, the project will assume the 12 -inch connection to Division Street which would increase the available fire flow from 86 percent of the fire flow goal to 262 percent.

The deficient hydrant is located on the 4 -inch main mid -block on the east side of North 3rd Street. The project would shift the main feeding the hydrant from the 4 -inch main to the 8 -inch main. The project would install approximately 80 LF of 6 -inch DI pipe to make the connection. This would increase the available fire flow from 61 percent of the fire flow goal to 230 percent. Figure 3-27. North 3rd Street Hydrant Improvement July 2017 1 3-73 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Bartlett Place and Gordon Road Waterline Fire Flow Improvements (D-5) Three dead-end water mains would be looped as part of the project improving fire flow to the area. The first dead-end main is a 6 -inch pipe that runs along Bartlett Place west of North 1st Street that dead -ends at the end of the street with a hydrant located at the end of the main. The second dead-end main is a 6 -inch pipe that runs west of the North 1st Street and East N Street intersection with a hydrant located at the end of the main. Both of these hydrants were found to not meet the fire flow goal. The third dead-end main is an 8 -inch pipe on the south end of Gordon Road. The project would install new 8 inch DI pipe to provide looping of three dead-end mains in the area by beginning on the west end of Bartlett Place and adding an 8 -inch DI pipe going north The dead-end mains on East N Street and Gordon Road would be extended to connect to the 8 -inch DI pipe to provide looping Approximately 1,340 LF of 8 -inch DI would be installed as part of the project For the deficient hydrant on Bartlett Place, the project would increase the available fire flow from 62 percent of the fire flow goal to 139 percent. For the deficient hydrant west of the North 1st Street and East N Street intersection, the project would increase the available fire flow from 78 percent of the fire flow goal to 194 percent. The project would also increase fire flows to the hydrant on Gordon Road (although not currently deficient) by increasing available fire flow from 243 percent to 331 percent of the fire flow goal. Finally, the improvements would increase the ease of water flow in the nearby vicinity Immediately to the south of Bartlett Place, a hydrant on a dead-end main serving a Motel 6 (model node #179 in Table 3-20) would see the available fire flow increase from 93 percent to 100 percent of the fire flow goal.

A hydrant is located toward the end of the water main that only meets 86 percent of the fire flow goal. All parcels surrounding the water main are developed single family residential properties making looping of the line difficult and the next nearest hydrant is located 640 ft away to the east. To improve available fire flow for Chesterly Lane, the project adds an additional hydrant on Chesterly Lane near the intersection of North 34th Avenue where higher fire flows are available. Although this does not increase available fire flow to the hydrant at the end of Chesterly Lane, it provides a new hydrant closer to the looped water main on North 34th Ave which has over 2,400 gpm in available fire flow Figure 3-29. Chesterly Lane Hydrant Improvement July 2017 1 3-75 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan North 3rd Avenue Waterline Fire Flow Improvements (D-7) A 6 -inch water main dead -ends on the north end of North 3rd Avenue and has a hydrant located toward the end of the main. The project would increase fire flows to the hydrant by adding approximately 430 LF of new 8 -inch DI pipe to loop the North 3rd Avenue main with the water main in North 4th Avenue. The project would increase available fire flows from 85 percent to 228 percent of the fire flow goal. Figure 3-30.

Both hydrants do not meet the fire flow goal. The project loops the two mains by installing approximately 250 LF of 8 -inch DI pipe between the ends of each dead-end main. Looping the mains significantly increases available fire flow with the western hydrant seeing the available fire flow increase from 88 percent to 174 percent of the fire flow goal and the eastern hydrant seeing the available fire flow increase from 93 percent to 178 percent of the fire flow goal.

To improve available fire flow, the project loops the water main by using 8 -inch DI pipe to extend the existing water main to the west into Gardner Park. The new water main would then go north and connect to the existing 8 -inch water main along West Pierce Street. Approximately 460 LF of 8 -inch DI pipe would be installed. The project would increase the available fire flow at the end of Perry Street from 92 percent to 275 percent of the fire flow goal. Figure 3-33.

The hydrant is on a 6 -inch main along South 4th Avenue that extends approximately 180 ft south of Stewart Street before going east along the north side of the Southgate Shopping Center parking lot where it connects to an 8 -inch main on South 3rd Avenue. The east -west portion of the main (approximately 330 LF) is only a 4 -inch pipe. To increase available fire flow, the project adds an additional 8 -inch pipe on Stewart Street between South 4th Avenue and South 3rd Avenue (approximately 310 LF). The project would increase the available fire flow at the hydrant on Stewart Street from 96 percent of the fire flow goal to 260 percent Alternatively, an 8 -inch pipe could be added on Stewart Street between South 4th Avenue and South 5th Avenue (approximately 330 LF) which would increase the available fire flow to 200 percent of the fire flow goal.

The hydrant is fed by a water main that runs along South 6th Street between East Yakima Avenue and East Walnut Street. Between East Chestnut Avenue and East Walnut Street the water main is 6 -inch while between East Yakima Avenue and East Chestnut Avenue the water main is 4 -inch. To increase fire flows to the hydrant, the project replaces the 4 -inch water line with 8 -inch DI pipe (approximately 460 LF). The project would increase available fire flows from 98 percent to 206 percent of the fire flow goal Figure 3-35. South 6th Street and East Chestnut Avenue Hydrant Improvement July 2017 1 3-81 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan East Mead Avenue Water Main Fire Flow Improvements (D-13) The existing 8 -inch main on East Mead Avenue east of South 1St Street is a constraint to conveying higher fire flows to the commercial/industrial area along 1-82. Although currently not identified as a deficiency given the current fire flow goals, the City would like to provide greater flows to this area to support future industrial and commercial development in the area. An improvement completed under an earlier CIP should be extended to include a 12 -inch main along East Mead Avenue between South 1st Street and the existing 12 -inch pipe that extends eastward from South 10th Street. This project would replace the existing 8 -inch in Mead from South 1St Street to South 10th Street and replace about 300 ft of existing 6 -inch in South 1St Street with a 12 -inch main As an example, at the intersection of East Mead Avenue and Rudkin Road, available fire flows would increase by almost 30 percent increasing from 5,095 gpm to 6,480 gpm (assumes Viola Avenue Freeway Crossing Improvements is also completed) Similar increases in available fire flow would be seen in areas along Rudkin Road and East Mead Avenue Figure 3-36.

Currently, there is no waterline in portions of Fruitvale Boulevard between Chesterly Dr. (private road) and North 29th Avenue. This project would install a new 12 -inch waterline and would make water service available to customers in this area. The project would also provide looping in the area, improving fire flows and improve water quality by eliminating an existing dead-end waterline. Figure 3-37.

The existing 16 -inch OD Steel water main has deteriorated and required periodic repair due to leaks. Replacement of the line will reduce unscheduled repairs, as well as improve system operation. Figure 3-47 Hathaway Street Waterline Improvements Distribution Main Leak Detection (D-27) In 2008/09, the City of Yakima conducted an extensive leak detection program. The program used extremely sensitive sound amplification instruments and a computer-based leak correlation program to help pinpoint the location of the leaks. Approximately 280 miles of the distribution system were included in the program. In this program, 15 leaks were detected and repaired in water mains, meters, hydrants, service lines, service connections, and valves Since 2009, over 30 main breaks have occurred and have been repaired Other leak detection and repair programs had been previously conducted in 1996, 1997, 1999, and 2000 Although the new Advanced Metering Infrastructure (AMI) system is almost fully implemented, which has included replacement of galvanized water services, the distribution system leakage is still estimated at nearly 15 percent. With aging cast iron pipe as a majority of the distribution system pipe material (including lead/oakum joint pipe), it is likely that there are system leaks due to main breaks or failed joints that are currently undetected. This project would provide a detailed leak detection survey throughout the distribution system on 4 -inch to 24 -inch diameter pipe, as well as valves, fire hydrants and water services. 3-94 1 July 2017 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan Del Monte Site Waterline Replacement (D-28) Currently, the existing 8 -inch CI and 12 -inch CI public waterlines located on the Del Monte property at West Walnut Street/West Pine Street/South 1St Avenue are underneath existing buildings. This presents a liability to the City should a water main break occur, and repair and maintenance of these waterlines is not possible. This project would abandon the existing waterlines and install a new 12 -inch waterline around the south end of the existing building (West Pine Street), as well as a new BNSF railroad crossing to South Front Street. Project cost may possibly be shared with Del Monte. Figure 3-48. Del Monte Site Waterline Replacement Advanced Metering Infrastructure (AMI) Battery Replacement / System Upgrade (D-29) AMI has improved meter reading accuracy, billing accuracy, identified customer usage patterns, potential customer leaks, and provided improved customer service. Components of the AMI system include water meters, transmitters, data collection units, and software. Over time, components of the system will require upgrade or replacement, including software, hardware, batteries or other associated infrastructure. For example, over 19,000 water meter data transmitters require the use of batteries, which have a life expectancy of approximately 20 years. Replacement of the battery will also include replacement of the transmitter and meter register. This project would provide funding for the on-going planned, or sometimes unexpected, replacements or upgrades. With a 20 year life expectancy on batteries, major replacement work will likely begin around 2030.

Replacement of the undersized lines will improve overall system performance, improve fire flows, and provide for future development. Replacement will also eliminate aging waterlines, which will require on-going repair. Depending on the area, replacements may also include waterlines identified as part of the Lead Oakum Joint Waterline Replacement program. In parts of the City, private water mains have been brought into the City's system This program replaces those mains less than 6 -inch (in some cases 1 -inch galvanized) and completes loops in the areas where these mains are replaced. This improves domestic flows to current residential customers, provides fire protection in areas where no fire hydrants have previously existed and improves overall system performance and reliability by looping the new mains to existing mains. As part of these replacements, the city will continue its efforts to remove lead gooseneck connections as well as any other lead appurtenances in the water system as they are discovered Water System Expansion New Waterline Installation in Unserved Areas (D-31) This project installs all new water facilities — waterlines, water services and fire hydrants — in areas of the City which currently do not have public water facilities. Currently, properties in these areas have individual wells, some of which are shallow and improperly constructed according to current standards. Installation of the new facilities would provide fire protection to these area, provide water service to properties (once appropriate connection fees are paid) and provide for future development within the area. Projects may be coordinated with proposed sanitary sewers projects in the same areas. Mill Site Redevelopment (D-32) In conjunction with private developer funding, this project installs waterlines and facilities in the currently underdeveloped area of the old Boise Cascade lumber mill site (west of I- 82 and north of North Fair Avenue) The project may replace existing, undersized facilities to provide adequate flows to new development at the site, and it may also replace existing facilities that are in poor condition and are incapable of providing for the future needs of the area. The project may also add new waterlines to the site depending on demands of new development. Limiting Factors and Carrying Capacity A key element of this WSP is the evaluation of the capacities of various water system elements and their abilities to support current and projected future water supply needs Resulting from these evaluations are "carrying capacities," or the maximum number of equivalent residential units (ERUs) that existing facilities can support Such analyses aid in identifying capacity deficiencies and provide the foundation for some capital improvement projects Table 3-21 summarizes the carrying capacities associated with the City's primary water system components This summary is formatted consistent with "Worksheet 6-1" of the DOH Water System Design Manual (December 2009) Details regarding source and storage capacity analyses are provided earlier in this section of the WSP By comparing this carrying capacity with the demand forecast presented in Chapter 2, it can be seen that existing facilities are able to support current demands and needs projected through the 20 -year planning horizon 3-96 1 July 2017 ERUs 6 Multi -Fame Commercial 6 52 2,156 15,978 Chapter 3 — System Analysis City of Yakima 2017 Water System Plan A carrying capacity analysis has not been conducted for the City's distribution facilities for the following reasons. It is difficult to characterize ERU carrying capacities in terms of piping, etc. Water mains are typically designed to convey fire flows. In the case of the City's system, this means that they are also more than adequate to support the average and maximum day demands imposed by customers. Some deficiencies have been identified throughout the system regarding the capability of certain sections of distribution piping to convey required fire flows at minimum pressures Such deficiencies, however, are not a function of the amount of current or proposed ERUs, and therefore do not factor into a carrying capacity analysis Table 3-21.

It is also required by the Department of Ecology (Ecology) when applying for new water rights. The applicable conservation program requirements and guidelines are contained in Water Use Efficiency Guidebook, Third Edition, May 2016 (DOH 331-375). The requirements for a conservation program vary based upon water system size and whether or not additional water rights will be needed within twenty years. In all cases, the larger the size of the system, the more detailed and comprehensive the program Additionally, if water rights are identified as being necessary within twenty years in the system's water demand forecast, the conservation planning must also include WUE measures as part of the supply alternatives evaluation A conservation program, as presented in this chapter, is one of the three required elements of a conservation plan. The other two elements, water use data collection and water demand forecasting, are discussed in Chapter 2, Basic Planning Data and Water Demand Forecasting. 4.1.2 Water Use Efficiency Requirements and Compliance Summary In 2003, the Washington State Legislature passed Engrossed Second Substitute House Bill 1338, better known as the Municipal Water Law, to address the increasing demand in the State's water resources. The law established that all municipal water suppliers must use water efficiently in exchange for water right certainty and flexibility to help them meet future demand. The Legislature directed DOH to adopt an enforceable conservation program, which became effective on January 22, 2007. Table 4-1 summarizes the conservation program requirements and the City's compliance status for each requirement July 2017 1 4-1 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan Table 4-1.

For example, the City has implemented a conservation rate structure for single family, multifamily, and nonresidential customers. Therefore this counts as three WUE measures. A summary of these measures over the last six years is shown in Table 4-2. The details of each measure are discussed below. Table 4-2.

SF = single family, MF = multifamily, NR = non-residential. 1. Source Meters Source meters are a critical conservation tool since accurate water production data is used in developing conservation priorities, goals, and programs The City has source meters on its Naches River WTP and all of its wells All of these meters are verified by a third party contractor on a bi-annual basis 2. Service Meters Service meters at customer connections are another key component of providing accurate water information for conservation planning The City has meters on all service connections Over the past 6 years, the City replaced or upgraded all of the existing meters with advanced metering infrastructure (AMI) (discussed further in Section 4.1.4). 4-4 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan 3. Meter Calibration The City has conducted audits to determine proper meter size and has replaced over 200 meters with smaller meters that improve accuracy for those users. The City has also implemented an intensive meter calibration program for all meters over 1.5 inches. These efforts enable the City to more accurately measure water consumption and provide the basis for detecting leaks and evaluating conservation opportunities. 4. System Leak Detection and Repair The City has conducted an extensive and ongoing leak detection program. The program has used extremely sensitive sound amplification instruments and a computer-based leak correlation program to help pinpoint the location of leaks Approximately 220 miles of the distribution system (90 percent of the total system) were included in the program In this program, 85 leaks were detected and repaired in water mains, meters, hydrants, service lines, service connections, and valves It should be noted that repair of these leaks did not significantly reduce the observed distribution system leakage (DSL) As such, the City anticipates that DSL is due to inaccuracies in meter reading and the City's billing system In addition, the City's leak detection program includes conducting leak detection surveys every few years The City's leak detection efforts are described further in Section 4 1 5 5. Conservation Rate Structure In October 2007, the City conducted a Cost of Services and Rate Study which established a transition to a conservation rate structure. In 2009, the City switched from a declining block rate structure to a single block conservation rate structure This rate structure applies to residential and nonresidential customers The City completed a rate study in 2012 and an update in July 2013 that analyzed additional conservation rate options Sewer use charges are linked to water consumption This is an additional incentive to conserve water because sewer use rates are higher than the water rates per hundred cubic feet 6. Bills Showing Consumption History In 2010, the City began including consumption history in utility bills for both residential and Industrial/commercial customers In 2015, the City established an Internet portal that customers can access to view their billing records and water use 7. Educational Bill Inserts The City distributes bill inserts providing water system users with information on water efficiency measures The inserts also direct customers to the City's website for additional information on leak detection and additional water efficiency measures 8. Additional Conservation Outreach The City has implemented a number of public outreach activities aimed at conveying water conservation messages. These activities include the following: • Brochures: Since 1989, the City has distributed water conservation brochures to educate the public about water conservation, promoting indoor and outdoor conservation practices These brochures have been distributed by city staff and displayed on the City's website and at the Utility Billing, Public Works, and City Clerk's offices • WaterSense Program: The City of Yakima joined the WaterSense program in September 2010 WaterSense Is an EPA -sponsored partnership program, launched in 2006, that seeks to protect the future of our nation's water supply by promoting water efficiency and enhancing the market for water -efficient products, programs, and July 2017 1 4-5 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan practices. The City has continued to promote this program to help water users identify water -efficient products and programs that meet the WaterSense water efficiency and performance criteria. In addition, the City has adopted the 1993 Uniform Building Codes which mandate low use plumbing fixtures. • Water Conservation Website: The City encourages a conservation ethic through its website which provides customers with indoor and outdoor water conservation guidance and recommendations • Integrated Plan Partnership: In 2009, the City partnered with the U.S. Bureau of Reclamation, Ecology, and other stakeholders in the Yakima River basin to develop the Yakima Basin Integrated Plan (described in Section 1 4 9) The Integrated Plan provides a comprehensive approach for addressing the basin's water resource problems and ecosystem restoration needs An element of the Integrated Plan is to enhance municipal water conservation in the basin As part of this effort, the City has partnered with other municipalities and agencies in the basin to identify best management practices for water conservation and develop basin -wide resources that promote municipal water conservation. For example, in 2015, the City worked with Integrated Plan partners to produce a water conservation brochure that was distributed throughout the basin. • Outreach Letters: In 2015, the City distributed water conservation letters to local government entities, schools, and community groups to help promote efficient water use. This letter encouraged customers to conserve water, especially during periods of drought, and provided recommendations for implementing conservation measures. 9. Use of Reclaimed Water All water from a potable source used at the wastewater treatment plant (VVVVTP) is metered. Since the late 1970s, reclaimed water has been used for all wash downs and for irrigation at the VVVVTP. The VVVVTP uses 1.0 to 1.3 million gallons (MG) of reclaimed water a day. Historical Conservation Program Savings The City's historical conservation program has focused largely on promoting a conservation ethic within the City through the use of price signals and educational outreach Water savings associated with promoting a conservation ethic can be difficult to quantify. In 2004, the City established a residential water use goal of 74.9 gallons per capita per day (gpcd). Since 2004, per capita water use has gradually declined from an estimated 78.8 gpcd in 2004 to 71.7 gpcd in 2015. These estimates are based on total residential consumption and water service area population in these years This shows a reduction of approximately 7 1 gpcd over the last 12 years Since 2009, per capita water use has declined by approximately 3 7 gpcd The City has been able to achieve this goal despite moderate population growth in the water service area This reduction in water use is likely partially attributed to the City's conservation program However, the City recognizes that reductions in water use are also influenced by other factors, such as the proliferation of more efficient appliances and fixtures, drought conditions such as those that affected the region in 2015, and the 2008 economic recession and its lingering social and economic effects Between 2004 and 2009, the average annual DSL estimate was 19.5 percent. Between 2010 and 2015, the average annual DSL estimate was 10.8 percent. This suggests a reduction in DSL of approximately 8.7 percent over the last 12 years. This reduction in DSL has likely contributed to the reduction in per capita water use However, it should be noted that DSL estimates between 2004 and 2015 have been highly variable, ranging from 31 7 percent in 2008 to 3 1 percent in 2012 Ongoing leak detection efforts over the years have failed to identify any significant amounts of actual leakage in the distribution system Therefore, it is likely that the variability in estimated DSL can be attributed to the City's billing system not recording all water sales Therefore, efforts to better understand and reduce DSL have focused initially on upgrading the billing system and undertaking a meter replacement 4-6 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan program. The City implemented a new utility billing system in 2016, making it possible to better account for water use. The City also completed implementation of its AMI system in 2016. While a portion of this reduction in DSL is likely due to the implementation of WUE leak detection measures, it will be difficult to quantify these reductions until the new billing system and AMI system are fully operational. The City has also generated potable water savings through the use of reclaimed water at the City's WWTP. The WWTP currently uses approximately 1.0 to 1.3 MG of reclaimed water a day for facility operation and irrigation. By using reclaimed water at the WWTP, the City is able to reduce the demand on the potable water system which would have been used if reclaimed water had not been available. 4.1.4 Conservation Program (2018-2027) The elements included in the conservation program include the following • Conservation Program Goals and Objectives • Evaluation of WUE measures • Selection of WUE measures for implementation These elements are outlined in the following subsections Water Use Efficiency Program Goals and Objectives The regulation (WAC 246-290-830) requires the governing body of the municipal water system (the Yakima City Council in this case) to establish WUE goals through a public process The WUE goals were re-evaluated as part of this 2017 Water System Plan update and will be discussed in a public hearing as part of the City Council meeting adopting this plan A copy of the Council Action Minutes from that meeting and a signed copy of the resolution adopting the Water Use Efficiency Goals are included in Appendix B The hearing allowed for public input on the proposed goals The WUE goals established through this process are as follows 1. Reduce DSL to 10 percent or less by January 1, 2019 2. Maintain a residential water use goal of 74.9 gpcd In addition to these goals, the City has established four main objectives for its conservation program: 1 Minimize impact of conservation program on domestic water rates 2. Encourage conservation ethic through increased customer awareness 3 Reduce commercial and industrial water consumption 4. Comply with DOH guidelines and state law Evaluation of Water Use Efficiency Measures DOH requires systems with more than 10,000 service connections (such as the City of Yakima) to implement at least nine WUE measures Specific WUE measure implemented for different customer classes, count as multiple WUE measures The evaluation and selection of measures relates to the cost-effectiveness of the measures During the preparation of the 2004 water system plan update, the City evaluated an initial list of 25 potential conservation measures The list included measures implemented by other northwest water utilities and the minimum program measures required by DOH From these 25 measures, the measures that were deemed to be applicable to Yakima were placed on a "short list" for more detailed evaluation From this list, the City selected those measures to July 2017 1 4-7 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan implement that were cost-effective for their system (see Section 4.1.3 for summary of historical conservation measures). During this water system plan update, the City considered historical conservation measures and potential new measures that contribute to the conservation goals and objectives Based on this, the City selected measures for implementation over the next 10 -year planning period Table 4-3 summarizes the measures that the City selected for 2018 through 2027 The following subsections provide a description of each measure. Table 4-3.

Advanced Metering Infrastructure In 2016, the City finished implementing an AMI system. This involved replacing and upgrading all existing water meters Components of the AMI system include new water meters, radio transmitters for existing water meters, structures for data collection units, and AMI software. The AMI system will allow for real-time monitoring and geocoding of consumption data. The system will allow the City to evaluate water use, consumption, and DSL, as needed. The system will also improve the City's ability to evaluate the effectiveness of WUE measures, educate customers about leak detection, and support future water system planning 2. Conservation Rates The City plans to continue with the existing single block conservation rate structure. In 2017, the City plans to conduct another Cost of Service and Rate Study. This study will consider additional conservation rate options. 3. Water Bills Showing Consumption History The City plans to continue to provide customers with water bills that show consumptive history. This measure allows customers to compare the percentage increase or decrease in water use over the same period from the previous year. 4-8 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan 4. Educational Bill Insen, The City plans to continue customer leak detection education using billing inserts. Bill inserts direct customers to the City's website for additional information on leak detection and other water efficiency measures, such as EPA's WaterSense program and Pacific Power and Cascade Natural Gas incentive programs for water efficient fixtures and appliances. 5. Additional Conservation Outreach The City plans to continue public outreach activities aimed at conveying water conservation messages. These activities include the following: • Brochures: The City plans to continue distributing water conservation brochures to educate the public about water conservation and promote indoor and outdoor conservation practices • WaterSense Program: The City plans to continue to promote WaterSense to help water users identify water -efficient products and programs • Water Conservation Website: The City plans to continue encouraging a conservation ethic through its website which provides customers with indoor and outdoor water conservation guidance and recommendations. • Integrated Plan Partnership: As part of the Integrated Plan, the City plans to continue its partnership with other municipalities and agencies in the basin to develop basin -wide municipal conservation resources, advance components of a municipal conservation program, and conduct outreach to water users and elected officials. This will contribute to promoting a conservation ethic within the basin and the City. 6. Use of Reclaimed Water at the Wastewater Treatment Plant The City plans to continue using 1.0 to 1.3 MG of reclaimed water a day at the WWTP. (See Section 4.1.6 for a discussion of other water reuse options evaluated.) 7. Low -Water Demonstration Gardens In 2016, the City received a grant from Ecology and other contributors to design and install low-water demonstration gardens. In 2017, the City plans to complete installation of demonstration gardens at the Yakima Public Works office and a downtown site on Yakima Avenue. Each site will include signage to educate the public about low-water landscapes. Photos and information about the gardens will also be posted on the City's website for water users to view. 8. Irrigation Efficiency Demonstration Projects As described above, the City plans to install demonstration gardens at the Yakima Public Works office and a downtown site on Yakima Avenue. These demonstration gardens will use efficient irrigation system technologies, such as wireless irrigation control systems. Each site will include signage to educate the public about efficient irrigation practices. Photos and information about irrigation efficiency will also be posted on the City's website for water users to reference. July 2017 1 4-9 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan Additional Measures Considered But Not Selected for the 2018-2027 Conservation Program In addition to the measures selected, the City considered other potential conservation measures. However, due to financial considerations, the City decided not to implement these measures at this time. The following subsections summarize the additional measures that the City considered. Retrofit Kits and Residential Water Audits The City considered including retrofit kits, toilet flappers (devices that regulate the amount of time for filling the toilet bowl), and residential water audits in their conservation program for 2018 to 2027. However, the City determined that these measures produce limited water - saving benefits and are expensive to implement. For example, toilet flappers often require installation by utility personnel since those mailed to customer are frequently not installed. Similarly, residential water audits involve hiring a utility representative. Audits typically take approximately one hour and must be applied to many customers In addition to consultation and installation, the cost of the audit also includes scheduling, follow-up, and the conservation devices Due to labor costs, the City determined that these measures were not cost-effective at this time Commercial/Industrial Audits Like the residential audits, commercial/Industrial can be time-consuming and expensive for the City to conduct Despite being unable to implement these measures at this time, the City still plans to support reductions in commercial and industrial consumption where possible Estimated Conservation Program Savings Savings from Water Use Efficiency Measures The City's future conservation program will continue to focus largely on promoting a conservation ethic within the City through the use of price signals and educational outreach. Water savings associated with promoting a conservation ethic are difficult to quantify. Therefore, the savings from educational measures were not quantified as part of this Water System Plan update The following summarize the expected savings from each WUE measure 1 Advanced metering infrastructure: The City would use AMI data to inform customers of potential leaks. The savings from improved customer leak detection is unknown at this time. The City will be able to quantify these savings after several years of collecting AMI data. 2. Conservation rates: The City plans to maintain the existing conservation rate structure. This is expected to sustain existing water use levels. 3. Water bills showing consumption history: Water savings are expected as part of promoting a conservation ethic 4 Educational bill inserts: Water savings are expected as part of promoting a conservation ethic. 5. Additional conservation outreach: Water savings are expected as part of promoting a conservation ethic 6 Use of reclaimed water at the WWTP: The City plans to maintain the level of reclaimed water use at the WWTP (1.0 to 1.3 MG per day). Over the next ten year planning period, this measure will save approximately 3,650 to 4,745 MG of potable water. 4-10 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan 7 Low-water demonstration gardens: Water savings are expected as part of promoting a conservation ethic 8. Irrigation efficiency demonstration projects: Water savings are expected as part of promoting a conservation ethic Although it is difficult to quantify the water savings expected from individual WUE measures, the City expects that these measures will help to sustain the water savings achieved through the City's historic conservation program (described in Section 4 1 3) Therefore, the City plans to maintain a residential water use goal of 74 9 gpcd The 2015 per capita usage was estimated to be 71 7 gpcd (see Table 2-10) The 5 year average (2011 to 2015) per capita usage was estimated to be 70 0 gpcd This is already a low per capita water use level The City recognizes that low water usage in recent years may be a short-term response to recent drought and the lingering effects of economic recession Therefore, it is possible that this low level of water usage does not reflect long-term water use trends As such, the City anticipates that additional reduction in water use would be difficult to obtain and are likely not financially feasible This is especially true since the City has a separate irrigation supply, so opportunities to reduce outdoor potable water uses are limited As such, the WUE measures selected for 2018 through 2027 are intended to maintain the existing per capita water use level Therefore, no additional water savings are expected from these WUE measures over the next 10 -year planning period. Savings from Improved Leak Detection The City plans to reduce DSL to 10 percent or less. Based on ongoing leak detection efforts, the City speculates that high DSL estimates are attributed to the City's billing system not recording all water sales. As such, it is likely that actual DSL is already under 10 percent. Efforts to better understand and reduce the DSL have therefore focused on upgrading the billing system and implementing AMI. The City completed implementation of the new billing system and AMI system in 2016. Moving forward, this will allow the City to more accurately estimate DSL and better evaluate the effectiveness of the conservation program. Note that the expected savings from improved leak detection are separate from the savings generated by the WUE measures. Because DSL accounts for a portion of the per capita water use estimate, the new billing and AMI systems will allow the City to determine the accuracy of the current per capita water use estimate and evaluate the effectiveness of WUE measures to determine if a new per capita goal is appropriate. The City will reassess the per capita water use goal after gathering several years of AMI data. 4.1.5 Water Loss Control Action Plan The City of Yakima established a WUE goal to reduce DSL to less than 10 percent by January 1, 2019 The estimated DSL for 2015 was 14 5 percent (see Table 2-6) The estimated three-year average (2013-2015) DSL was 12.7 percent. This is slightly above the WUE Rule requirement (DSL at 10 percent or less). The City has implemented the following actions to achieve the DSL goal: • Implementation of a new billing system (put on line in 2016). • Implementation of an AMI system (fully complete in 2016). • A new source meter on each of the seasonal wells. • Ongoing transmission main and distribution system leak detection monitoring and repair The City has not detected any significant amount of leakage in either the transmission main or the distribution system. The City anticipates that the apparent DSL is due to the City's billing system not recording all water sales. Implementation of the AMI system and a new utility billing system in 2016 is expected to resolve this issue. The new AMI system will allow real-time water meter reads to be transmitted to the utility billing system, eliminating the need July 2017 1 4-11 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan for manual meter reading. This is expected to improve meter reading and billing accuracy, and enhance identification of customer usage patterns and potential leaks. The city also has a program to calibrate source meters every two years as needed, and to calibrate service meters over 1.5 inches as recommended in the maintenance manuals provided by meter vendors. 4.1.6 Water Reuse An inventory of the potential sources and uses for reclaimed water is required under WAC 246-290-100 to be included in the conservation plan. Reclaimed water is commonly used for landscape irrigation, agricultural irrigation, or industrial processes. The feasibility of using reclaimed water as a water supply depends upon the quality and quantity of the reclaimed water, the requirements of the intended application site, the economics of treating, supplying, and distributing the reclaimed water, and public acceptance. A discussion of the regulations governing the use of reclaimed water and the potential sources and uses is presented in the following subsection. The use of reclaimed water was not included in the current conservation plan except for its continued use at the WWTP. Regulations In 1996, Chapter 90 46 RCW was enacted by the legislature to address reclaimed water use In passing this legislation, the legislature has encouraged the development of wastewater reclamation and reuse facilities and the use of reclaimed water for domestic, agricultural, industrial, recreational, and fish and wildlife habitat including wetlands The legislature directed DOH and Ecology to coordinate efforts towards developing an efficient and streamlined process for creating and implementing processes for the use of reclaimed water The legislature declared that the people of the state have a primary interest in the development of facilities to provide reclaimed water to replace potable water in non -potable applications, to supplement existing surface and groundwater supplies, and to assist in meeting future water requirements of the state The legislature also declared that the use of reclaimed water is not inconsistent with the policy of anti -degradation of state waters as provided under Chapter 90 48 RCW and Chapter 90 54 RCW Reclaimed water facilities are water pollution control facilities as defined in Chapter 70.146 RCW and are eligible for financial assistance as provided in that RCW. DOH and Ecology issued final water reclamation and reuse standards in September of 1997 (Publication #97-23) These standards, as directed by the legislature, were the result of a joint effort by Ecology and DOH While the standards are primarily administered by the DOH for facility plan review, Ecology has state wastewater discharge permitting authority under the provisions of Chapter 90.48 RCW. The 1997 Reclamation and Reuse Standards establish requirements for wastewater treatment and reuse A multi -tiered (Class A through D) reclaimed water classification system defines the characteristics of the reclaimed water for each class (defined in Publication #97-23) Reclamation and reuse regulations specifically identify groundwater recharge as a beneficial use, and reclaimed water can be used to mitigate water rights limitations, should they exist. Potential Sources Effluent from wastewater treatment plants is the most common source of reclaimed water for municipal applications, however, other sites may also serve to provide a source of water for reuse, depending on the reliability and treatment requirements of the applied water. The primary source of reclaimed water in the City is the Yakima Regional WWTP, located between Interstate 82 and the Yakima River. The activated sludge plant is operated by the 4-12 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan City and primarily discharges secondary treated effluent into the Yakima River. The VVVVTP is the most likely source for reclaimed water for additional uses within the City. Potential Reclaimed Water Users The feasibility of using reclaimed water depends on the volume and quality of the source, the size and location of suitable application sites and the proximity of the source to the application or use sites. Table 4-4 presents an inventory of potential reclaimed water users located within 2 miles of the VVVVTP, which was considered to be the most likely source of water. As the distance from the source increases, the economic feasibility of serving reclaimed water typically diminishes unless there is a large, constant user available. Potential users were identified based on maps of the area and a listing of the top 20 water users. Potential Reclaimed Water Users within 2 Miles of the WWTP Application Number Golf courses 1 Parks and arboretum 9 Schools 5 Industrial/commercial facilities 4 Nurseries 1 freeway landscape irrigation 1 Yakima WWTP 1 Misc -pipeline flushing, street cleaning dust control, etc There are four Industrial/commercial entities with high water use located within a 2 -mile radius of the VVVVTP Two of these entities are involved with food handling or production Based on water use patterns, the other two entities appear to predominately consume water for indoor uses, so use of reclaimed water would likely require costly retrofitting of these facilities to install separate reclaimed water plumbing. Based on these considerations, use of reclaimed water at these locations is unlikely at this time. The remaining reuse applications could potentially use a range of Class A to Class C reclaimed water, depending on the specific water quality requirements of each use as described in the Water Reclamation and Reuse Standards (September 1997, Department of Health and Department of Ecology, Publication No. 97-23). Although use of reclaimed water in Yakima may be technically feasible, some institutional constraints must be considered The unit cost of potable water is relatively low in Yakima, so the unit cost of reclaimed water may exceed the unit cost of potable water and may be difficult to sell Although the use of reclaimed water to help meet large-scale agriculture's irrigation needs would likely be acceptable, the quantities of reclaimed water that could be made available may be too small to justify the investment in reclaimed water facilities The use of reclaimed water to irrigate schools, parks, and other public landscaping may also encounter public skepticism unless it is accompanied by a public education program focused on the safe use of reclaimed water. In addition, the Bureau of Reclamation monitors return flows on the Yakima River at the Parker gage, downstream from the City of Yakima Flow levels at the Parker gage contribute to the Bureau of Reclamation's estimate for total water supply available, which is used to establish portioning levels If the City were to decrease releases from the VVVVTP, this would July 2017 1 4-13 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan reduce the return flows at the Parker gage. As such, the City would be subject to additional prorationing. Reduction of flows at Parker could also prompt other proratable users to seek remedies from the City. Based on these considerations, the City does not plan to pursue additional reclaimed water uses, beyond what is currently used at the WWTP, at this time 4.2 Source of Supply Analysis 4.2.1 General The purpose of a source of supply analysis is to evaluate opportunities to obtain or optimize the use of existing sources already developed, and evaluate other innovative methods to meet water supply needs. DOH planning guidelines require a source of supply analysis for systems that will be pursuing water rights within 20 years of approval of their WSP as defined by the water demand forecast (see Chapter 2, Basic Planning Data and Water Demand Forecasting) The City does not anticipate the need to pursue additional water rights within 20 years of the completion of this WSP update. For that reason, a formal source of supply analysis is not included here. However, the City has developed an ASR program to better utilize existing water rights, provide additional water supply, and improve water system reliability. Section 4 3 provides a summary of the City's current water rights status 4.2.2 Aquifer Storage and Recovery The City's ASR program involves diverting water from the Naches River during low demand periods (e g , the winter), treating the water to drinking water standards, delivering water through the City's distribution system to groundwater wells, and injecting (recharging) water through the wells into the aquifer (reservoir) The City would then withdraw the stored water at later times for municipal use The City's ASR program has been developed in close coordination with Ecology through extensive feasibility studies conducted over the last 16 years. Additional technical information regarding the ASR program can be obtained from the Ahtanum Valley Aquifer Storage and Recovery (City of Yakima ASR) report prepared by Golder Associates in 2015 (Appendix P) The City submitted Reservoir Permit Application R4-3552 to Ecology on April 12, 2002. This permit identifies the Upper Ellensburg aquifer in the Ahtanum-Moxee subbasin as the proposed aquifer storage reservoir for the ASR program. On February 24, 2015, Ecology issued a Temporary Permit for operation of the City's ASR system (2015 Permit). Between March and September of 2015, the City operated the ASR program under the 2015 Permit. Under the 2015 Permit, water may be recharged at the City's Kissel Park and Gardner Park Wells, and stored water may be recovered from any of the City's existing four wells. In March and April of 2015, a total of approximately 41 million gallons (125 1 acre-feet) were recharged over 31 days Recharge occurred only at the Gardner Park Well, with a maximum recorded instantaneous recharge rate of 1,368 gpm The City did not use any other wells for recharge and did not discharge to surface waters During 2015, the wellhead and distribution system performed well and there were no leaks or other problems with the wellhead observed during recharge or storage The City did not recover any of the stored water during 2015. All water recharged during 2015 is reserved for future recovery as provided in the 2015 Permit. Of the 125.1 acre-feet recharged in 2015, 100.1 acre-feet would be available for recovery in 2016 (80 percent of the 2015 recharge volume). If the City does not withdraw any stored water in 2016, the recoverable quantity available in 2017 would be 87.6 acre-feet (70 percent of the 2015 recharge volume). 4-14 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan The City conducted monitoring of groundwater -levels in 2015 as part of the 2015 Permit. Water levels in the Kissel Park, Kiwanis Park, and Airport wells increased throughout the recharge period. However, it is unclear how much water level changes may be attributable to recharge versus regional conditions, such as antecedent water level trends (e.g. recovery from pumping) and interference pumping from nearby wells. The City also conducted monitoring of disinfection byproducts (DBPs) in both source water (i.e., water being recharged into ASR wells) and stored water (i.e., water withdrawn from ASR wells), as required by the 2015 Permit. Water quality results in some instances exceeded the 2015 Permit limits for source water DBPs. However, water quality results were in compliance with drinking water standards in all samples (i.e., in both source water and stored water) at all times. By June 2015, DBPs had dropped to very low levels, indicating that the majority of DBPs introduced during recharge had been removed during normal operation of Gardner Park Well. The City prepared Standard Operating Procedures (SOPs) for the ASR program (Appendix Q) The SOPs address procedures for initiating recharge, monitoring and maintenance during recharge, terminating recharge, recovery, sampling, and coordination with Ecology The City provided the SOPs to Ecology for review before beginning recharge in 2016 Chapter 6, Operation and Maintenance, provides a summary of the operation and maintenance of the ASR system. In January 2017, Ecology issued a final Reservoir Permit (R4 -34552P) authorizing the City to recharge up to 14,400 acre-feet per year using the Gardner Park, Kissel Park, and proposed Southeast Area wells The Reservoir Permit also authorizes the City to use all of its wells for recovery of stored water The City intends to construct dedicated ASR wells that would recharge and withdraw water under the Reservoir Permit This will improve water system reliability, particularly for times when the City's Naches River surface water supply is temporarily unavailable The instantaneous quantities associated with these new wells would be additive to the City's existing groundwater rights The City would track annual quantities of water withdrawn from these new dedicated ASR wells against the recoverable quantities of stored water The City would likely take a phased approach to evaluating and implementing potential new ASR wells In identifying new ASR wells, the City would consider the aquifer characteristics and evaluate the impacts to the distribution system due to conducting recharge from multiple points in the system. The City would also continue monitoring of the ASR program at existing wells, including well efficiency and aquifer response, to help inform decisions regarding the siting of subsequent wells. 4.3 Water Right Evaluation 4.3.1 Permits, Certificates, Claims, and Applications The City of Yakima holds a number of water rights that supply the City's domestic water and municipal irrigation systems. All of these water rights are described in the following narrative and in Table 4-5, Table 4-6, and Table 4-7. The City holds several other water rights that are not discussed in this plan because they are not part of the City's municipal water distribution systems and are not used for domestic purposes The City's domestic water distribution system is primarily supplied by surface water, with diversions occurring at the City's Naches River WTP. The City currently uses its groundwater supply system as a seasonal/emergency backup supply, as defined by DOH. However, the water rights are not limited to standby/reserve status as defined by Ecology. The City also has two interties with the Nob Hill Water Association for emergency supply purposes. The City also owns a municipal irrigation distribution system The system is supplied by surface water with diversions occurring at the City's Nelson Bridge diversion By serving July 2017 1 4-15 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan some of the need for irrigation of residential property, the City's operation of the irrigation system lessens the demand on the City's domestic water distribution system. During times of drought, the City also sometimes transfers some of its Nelson Bridge water rights to the Naches River WTP for use in the domestic system. Water rights associated with the municipal irrigation system are therefore described in the following narrative and in , Table 4-6Table 4-7, and . All of the City's surface water rights are currently under the jurisdiction of the Yakima County Superior Court as part of the surface water rights adjudication (Ecology v. Acquavella, et al , Yakima County Superior Court, Cause No. 77-2-01484-5). On November 21, 2002, the Court issued a Conditional Final Order that approves a settlement of the City's Naches River water rights diverted at the Naches River WTP and at the Nelson Bridge diversion. Future steps will involve implementing the Conditional Final Order, including the Court's issuance of a Final Decree and Ecology's issuance of applicable certificate documents after issuance of the Final Decree. The surface water right parameters discussed in this Water System Plan are as set forth in the Conditional Final Order and underlying 2003 settlement. Groundwater right parameters are as provided in the underlying permits, certificates, and change authorizations. Surface Water Rights Summary 1.

Subject to a combined quantity limitation: 7,826 AF is the maximum combined annual quantity that may be diverted in any single calendar year under Certificate S4 -01141(A) and the portion of the Reclamation contract right diverted at the Naches River WTP. Combined quantity limitation does not apply to the portion of the Reclamation water right diverted at Nelson Bridge. Annual quantity was reduced in 2013 (from 5,083 AF). 7. Annual quantity was reduced in 2013 (from 1,500 AF). 8. The range of instantaneous quantities (Qi) available is a function of the system elements considered (Naches River WTP, Nelson Bridge, and groundwater wells), and the season (winter vs. summer). The "low" figure shown in the table only reflects water available as primary supply through the City's current domestic water supply system - the Naches River WTP. The figure therefore does not include water available at Nelson Bridge or through the groundwater supply system. Further, the figure only reflects water availability during the summer irrigation season (generally beginning of Bureau of Reclamation storage control through October 15). 9 The "high" Qi includes water available through all City municipal systems Naches River WTP, Nelson Bridge, and groundwater wells It also reflects water available during the irrigation season (summer) However, it does not include the Qi authorized under permit 54-01141(8) and permit 190 -A(B)P, because these instantaneous quantities are non -additive the quantities in the certificates for the respective water rights 10 Water right change CG4-CWC2581-A@2 (Conservancy Board decision YAKI-05-04) included a provision making the 3,350 AF of non -additive alternate supply available up to a combined total of 29,178 AF under all City rights existing as of June 2006 4-34 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan 4.4 Water System Reliability Analysis The purpose of the water system reliability analysis is to summarize the steps that can be undertaken to ensure an adequate quantity of water can be provided at all times. When water shortages or interruptions in service occur, public health can be threatened because customers may use other non -potable sources of water inappropriately, or system pressure may be reduced such that basic public health needs are not met or other back flow related problems occur 4.4.1 Source Reliability The primary water supply source for the City of Yakima is the Naches River WTP. Potential causes of reduction or interruption of this primary supply source include: • Spring runoff resulting in flooding and increased turbidities exceeding the process capabilities of the WTP • Extended periods of drought resulting in loss of river flow • More frequent droughts due to climate change • Bureau of Reclamation proration of water storage rights due to limited water availability in the Yakima River basin. • Failure of 48 inch transmission main transporting water from the WTP to the City's water distribution system. • Necessary modifications or upgrades to the WTP. • During winter months, the WTP supply could be temporarily reduced or interrupted due to icing of the intake structure or contact basins • Chemical, fuel, or other contaminant spill into the Naches River upstream from the WTP • Forest fire in Naches River basin resulting in unacceptable turbidity at the WTP • Volcanic eruption in Cascade Range volcanoes, delivering unacceptable quantities of ash to the WTP • Incidents resulting in damage to the WTP or other water system infrastructure (See Emergency Operations Guidelines [Appendix R]) The City has approximately 15.8 MGD available from the existing groundwater well supplies. The wells are categorized as seasonal sources of supply, and are typically only put into service in the event of the types of failures identified above. For example, the WTP was shut down from October to May, 2015 while the recycle lagoons were constructed at the WTP. During this time, the City was able to meet water demands using the City's four wells. In spring 1974, a failure of the Naches River WTP supply was caused by a break in the 48 - inch transmission main. The pipeline floated during flooding conditions and was out of service for approximately 3 months for repairs because a significant length of the pipeline was damaged. The configuration of the 48 -inch transmission main has since been altered to ensure that the pipeline is always full, eliminating the potential for flotation during flooding. It is estimated that the extent of any future failure of the 48 -inch pipeline would be limited to short lengths and could be repaired within 3 days. However, this type of failure would reduce the available supply to the entire system. The City anticipates that reduction or interruption in supply due to high turbidity or icing conditions would not last more than 3 days Other emergency conditions could create longer interruptions of available surface water supply The City also has two interties with Nob Hill July 2017 1 4-35 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan Water Association Prolonged supply from these interties cannot be relied upon because Nob Hill may not have excess supply capacity available in the summer months. Chapter 3, System Analysis, summarizes the water quality characteristics of the Naches River and groundwater supplies 4.4.2 Water Right Adequacy Existing water rights are expected to be adequate to supply demands over the next 20 years. Section 4.3 provides a detailed discussion of the status of the current water rights. The Bureau of Reclamation can prorate "contract rights" in water short years Under these conditions the seasonal well supplies are brought on line to make up the difference The City anticipates that ASR may be used in the future to further augment the well supplies in water short years (see discussion in Sections 4 2 2 and 4 4 4) Specific measures taken in response to water shortages are described in Section 4 4 4 4.4.3 Facility Reliability Chapter 3, System Analysis provides a discussion of the reliability of water system facilities and includes recommendations for improvements necessary to maintain the reliability and performance of water system facilities 4.4.4 Water Shortage Response Planning Short-term reduction or loss of the Naches River WTP supply due to raw water high turbidity, transmission main failure, or icing conditions in the WTP have historically lasted 30 days or less in winter and 3 days or less during summer The response to short-term disruptions such as these is to activate one or more of the seasonal well supply sources Depending on the magnitude and duration of the WTP supply disruption, it may be necessary to utilize some of the standby storage capacity and/or activate one of the interties with Nob Hill Water Association. Chapter 3, System Analysis, summarizes the storage capacity analysis including stand-by storage and emergency storage requirements The purpose of water shortage response planning is to identify measures that can be implemented during water supply reductions or interruptions These measures could include demand reduction, supply augmentation, or a combination of both Problem Assessment The City's 1902 surface water right of 10 cfs (6 5 MGD) for the Naches River WTP is a senior right The other rights for the WTP withdrawal are either only available in the winter, or are subject to proration or interruption in years of extreme water shortage During drought years, the Bureau of Reclamation can prorate the City's contract water rights The most severe prorationing in recent times occurred in 2001 when the Bureau of Reclamation prorated the City's contract water rights to 29 percent of normal during the summer months Additional prorationing was activated in 2005 (42 percent) and 2015 (44 percent) It was necessary during these periods to make up the supply shortfall by bringing the seasonal well supply sources on line By utilizing the seasonal wells it was not necessary to implement demand reductions in these years The Bureau of Reclamation and Ecology have conducted hydrologic modeling of climate change in the Yakima River basin as part of the Yakima River Basin Integrated Water Resource Management Plan, described in Chapter 1. The Yakima River basin could be adversely affected by climate change in the future Modeling suggests that droughts will become more frequent in the Yakima River basin in the future, including in the Naches River sub -basin Climate change may affect the timing and quantity of precipitation, how 4-36 1 July 2017 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan precipitation is stored and released from snowpack, and the demand patterns of water users The Bureau of Reclamation has incorporated three climate change scenarios into their hydrologic model of Yakima River basin: less adverse, adverse, and more adverse. These scenarios were adopted from climate -specific hydrologic modeling conducted by the University of Washington and represent a range of possible future climates. Under the adverse scenario, the total annual average reservoir inflow would decrease by 11 percent During the summer, natural runoff and streamflow in the basin would decrease by 50 percent or more Under these conditions, the Bureau of Reclamation would need to meet water supply demands and instream flow objectives by releasing larger amounts of water from the existing reservoirs In many years, the reservoirs would not be capable of meeting these demands Under these conditions, the adverse scenario shows an average reduction in September 30 prorationing levels of 21 5 percent compared to historical prorationing levels (resulting in water diversions under the City's Reclamation Contract Water Right being reduced by approximately 968 acre-feet, in addition to the reductions currently applied during prorationing). Reductions could be less severe or more severe under the other climate scenarios examined. Additional information about Reclamation's modeling of climate change conditions can be found in the February 2016 Hydrologic Modeling of System Improvements technical memorandum. Decreased streamflows could potentially impact the City's senior water rights if flow conditions in the Naches River decline to the point that the City cannot divert its full water right in order to maintain minimum instream flow requirements In addition, the City's groundwater rights are junior to Reclamation and other senior surface water right holders. As such, the City's groundwater resources are also subject to curtailment due to the connectivity of surface water and groundwater resources. Decreased natural runoff and streamflows could also reduce aquifer recharge and diminish the physical production from the aquifer over time If demands increase or droughts become more frequent, it may become necessary for the City to implement demand reduction measures and/or supply augmentation. The City has identified specific response measures that would be implemented in drought years. These are included in the City's Emergency Operations Guidelines (Appendix R). Some of these measures are also included in the suggested actions outlined in Table 4-8. The City's ASR program would contribute to maintaining aquifer water levels and help the City to augment water supplies if surface water resource decline in the future However additional measures could also be required Options for Demand Reduction in a Water Shortage In 2005, the City adopted an ordinance (Ord 2005-16 § 1, 2005) that provided authority for the City to implement restrictions on municipal water use during emergency situations that threaten municipal water supply, such as drought Under this ordinance, the city manager, upon a finding by the city council that an emergency situation exists which threatens to seriously disrupt or diminish the municipal water supply, may order and enforce restrictions on water use Selected demand reduction options would be implemented based on the degree of water shortage that exists. Stages of a water shortage and corresponding demand reduction measures include the following (source Preparing Water Shortage Response Plans, Washington State Department of Health, DOH PUB. #331-301, July 2011): • Stage 1: Minor Shortage - Voluntary Measures This is the first step in reducing water consumption during a potential or actual water shortage An appropriate response at this stage is initiation of a public information program July 2017 1 4-37 Public Information Actions Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan • Stage 2: Moderate Shortage — Mandatory Measures An appropriate response at this stage is to institute mandatory demand reduction measures, enforceable under the authority of special ordinances, or a revised rate schedule • Stage 3: Severe — Rationing Program An appropriate response at this stage is instituting rationing programs through fixed allotments or percentage cutbacks This response should be initiated only in rare circumstances It allows the maximum amount of water savings possible in a community without severe hardship. This action would have to be enforceable under the authority of special ordinances. Demand reduction options that the City could consider at each water shortage stage are summarized in Table 4-8 Table 4-8.

This data is monitored closely by the Bureau of Reclamation. The City would consult the Bureau of Reclamation personnel in early spring to assess the possibilities for water shortages in the upcoming summer months. Options for Supply Augmentation in a Water Shortage Thus far, the City of Yakima has been able to meet current demands even in water short years by supplementing the surface water supply with the seasonal well supply sources In 2001, 2005, and 2015 it was necessary to rely on the wells for a significant amount of the demand during the summer months The City could purchase additional surface water rights in the future if a willing seller could be found The recovery capacity of the four existing City wells is about 11,000 gpm (15.8 MGD). Since 2000, maximum day demand has ranged from approximately 16 to 24 MGD Assuming a maximum day demand of 24 MGD, the existing wells have about two-thirds of the capacity required to meet demand in the event of a total shutdown of the Naches River WTP New wells or other supplies may be advisable to increase system capacity in the event of a long- term shutdown of the WTP As described in Section 4.2.2, upon issuance of the final Reservoir Permit, the City intends to construct dedicated ASR wells that would recharge and withdraw water. These ASR wells would contribute to supplementing existing water supplies should future demands or supply conditions require additional supply sources. 4.5 Interties As discussed in Chapter 1, System Description, the City of Yakima has two interties with the Nob Hill Water Association. A summary of the interties, including location, size, hydraulic grade line, and other data, are included in Table 1-5. These interties are for emergency purposes only and are covered in a Memorandum of Understanding between the City and the Association dated September 6, 2000 (Appendix F). These interties are not designed for normal operation of either system and are not considered as a source of supply in the storage and supply analyses presented in Chapter 3, System Analysis. No new non- emergency interties are proposed or anticipated during the 20 year planning period The City has had preliminary discussions with Yakima County for an emergency intertie between the County's Terrace Heights system and the City system. However, any intertie for these systems would require a bridge crossing of the Yakima River. If a new bridge were to be constructed, provisions would be included in the design to provide the piping necessary to facilitate an intertie July 2017 1 4-41 Chapter 4 — Conservation and Water Resources City of Yakima 2017 Water System Plan 4-42 1 July 2017 This page left intentionally blank. 5 Source Water Protection 5.1 Source Water Protection Overview The objective of this chapter is to outline a program to protect, and if possible, improve, source waters used by the City of Yakima water system Source water protection for Group A systems is required under WAC 246-290-135, -668 and -690 The appropriate measures to be taken to ensure adequate source water protection depend on whether the source of supply is surface water or ground water. If the utility uses ground water, a wellhead protection program is required. A watershed control program is required for utilities using surface water. The City of Yakima's primary source of supply is surface water which is treated by the Naches River WTP In addition, the City currently has four groundwater wells which are used as seasonal sources of supply 5.2 Wellhead Protection Program The Upper Yakima Valley Regional Wellhead Protection Plan (WHPP) was completed in October 2000 and is updated periodically. The most recent update was submitted in 2015 (Appendix S). The purpose of this plan is to identify potential sources of contamination near the member purveyors' groundwater supplies, implement management strategies to prevent contamination of those supplies, and develop a contingency plan to mitigate contamination in the event that groundwater does become contaminated. In this WHPP, each member community in the Upper Yakima Valley plays a role in protecting the groundwater supplies of the entire area by pooling resources and management efforts to target an audience beyond that which could be reached at a local level The member purveyors participating in this WHPP make up the Regional Wellhead Protection Committee (RWPC); members include: • Yakima County • City of Yakima • Town of Naches • City of Moxee • Town of Tieton • City of Union Gap • City of Selah • Nob Hill Water Association The Town of Naches wellhead protection area also lies within the City of Yakima's surface water supply watershed. Regional management efforts adopted by the eight purveyors forming the RWPC include • Development of a Geographical Information System (GIS) database of the wellhead protection areas, potential contamination sources, and water quality data in order to monitor and track sources and potential receptors. • Development of a planning trigger to distribute wellhead protection notification letters for development changes (i.e. building permits, zoning changes, SEPA) within wellhead protection areas. July 2017 1 5-1 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan • Coordination with Ecology to prioritize their Hazmat Technical Assistance Sweep within wellhead protection areas • Coordination with the State Health Department's Sanitary Surveys to ensure up-to-date information is maintained in the regional GIS potential contamination source inventory. • Coordination with County Health District to identify septic tanks and private wells with Global Positioning System (GPS) units. • Coordination with the Washington Association of Realtors to adopt a Property Disclosure Addendum that will help to identify private and abandoned well locations during property transfers. • Designation of the 6 -Month wellhead protection area as a critical "Red Zone" by County Emergency Management (LEPC) in order to prioritize wellhead protection during emergencies (I e hazardous material spills) • Public education efforts including literature distribution • Coordination with Education Services District (ESD) which provides continuing education to area teachers in order to better integrate wellhead protection and water issues into school curriculum. • Development of a regional website to increase public awareness on the need to protect groundwater. • Development of a logo for wellhead protection area signs. • Development of an interlocal agreement among the eight purveyors to make sure that wellhead protection is given a high priority in the Upper Yakima Valley The City of Yakima's water system has wellhead protection areas (WHPAs) for its four drinking water wells (Airport, Kiwanis Park, Kissel Park, and Gardner Park) that were delineated using an analytical method. In the WHPAs, an inventory of existing and potential sources of groundwater contamination was compiled and mapped. The latest inventory was completed in 2015 which included windshield surveys of all well sites and an update of the Potential Wellhead Protection Contaminant Source Inventory Map. Additionally, the City mailed notification letters to businesses located within the wellhead protection areas including any new potential contaminant sources (Appendix S) 5.3 Watershed Uontrol Program 5.3.1 Regulatory Requirements/Program Overview Watershed control requirements apply to all Group A systems using surface water, (both filtered and unfiltered systems). A watershed control program is an integral part of a purveyor's overall strategy to ensure public health protection. The term "watershed" refers to the hydrologic drainage upstream of a utility's surface water intake. The watershed affects the physical, chemical and microbiological quality of the source. The watershed for the City of Yakima surface water source does not meet the criteria to remain unfiltered under the Surface Water Treatment Rule, which is detailed in Part 6 of Chapter 246-290 WAC The surface water supply has been filtered since 1971 when the City completed construction of the Naches River WTP 5-2 1 July 2017 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan A Watershed Control Program is required to include the following elements. 1 Watershed description and inventory, including location, hydrology, land ownership, and activities that could adversely affect drinking water quality 2. Inventory of all potential surface water contamination sites and activities located within the watershed. 3 Watershed control measures 4 System operations, including emergency provisions These elements for City of Yakima Watershed Control Program are summarized in the following sections. 5.3.2 Watershed Description Location The City of Yakima's primary source of water is the Naches River. The Naches River WTP is located approximately 3 miles southeast of the City of Naches, and approximately 4.4 miles downstream of the confluence between the Tieton and Naches Rivers. The Naches River drainage is located on the eastern slope of the Central Washington Cascades in the Wenatchee National Forest. Figure 5-1 shows the location of the watershed and Naches River WTP. The watershed area for the City's surface water supply consists of most of the area comprised by the State of Washington's Water Resources Inventory Area (WRIA) Number 38. Drainage Area The watershed drainage area that supplies the WTP is approximately 962 square miles. The Cleman Mountains form the divide between Wenas Creek and the Naches River and provide the northeastern boundary of the triangular-shaped drainage area. The west boundary is the Cascade Range and the southern boundary is formed by the Klickton Divide and Divide Ridge. The Naches River watershed is composed of two major subdrainages: the Tieton River drainage and the Naches River drainage; the divide between the two is Bethel Ridge. The two rivers join at the junction of Highways 410 and 12, and continue southeasterly as the Naches River The drainage area to the WTP does not include the Cowiche Creek Basin or parts of the Naches River basin that drain to areas downstream of the WTP The WTP's drainage area is part of the larger Yakima River basin and is approximately 15 percent of the total Yakima River basin drainage area. Hydrology The major streams and rivers in the Naches River watershed are shown in Figure 5-1 The average annual precipitation in the Naches River watershed ranges from 47 inches at the headwaters to 8 inches in the lower watershed A USBR stream gauge is located on the Naches River just downstream of the Wapatox Canal diversion Table 5-1 summarizes recent data for this gauging station July 2017 1 5-3 kune 611 2,393 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan 5-4 1 July 2017 Table 5-1.

The mid -watershed consists primarily of dry silty and loamy soils; some areas contain drainage -impeding hardpans. The lower -watershed is primarily dry, coarse, silty soils, some with lime layers at 2 to 4 feet, and dark, stony, rangeland soils, some with hardpan Topography Topographic features of the watershed are shown in Figure 5-2 Elevations in the watershed vary from about 6,800 feet near the western and northern watershed boundaries to about 1,300 feet near the WTP The Klickton Divide and Divide Ridge form the southern and south- eastern borders This ridge separates the Tieton River drainage from the Cowiche Creek drainage The northern border of the watershed is formed by several mountains and ridges including Blowout Mountain, Mt Clifty, portions of Manastash Ridge (west end), Quartz Mountain, Bald Mountain, and Clemen Mountain The watershed is primarily forested, but also contains flat valleys lying between steep forested or rock slopes that are used primarily for agricultural purposes or for livestock grazing Point of Diversion The Naches River WTP intake structure is located downstream of the Town of Naches WWTP In order to minimize the potential contamination of the river from a failure at the Naches WVVTP, the City of Yakima and the Town of Naches have established a notification process to respond to a contamination incident In addition, City staff has collected and analyzed river water samples and have determined that there is currently no reason for significant concern. City staff has developed emergency Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan operations guidelines that include procedures for responding to contamination events that might occur upstream of the intake structure (Appendix R). Wilderness and Protected Multi -Use Natural Areas The Naches River watershed includes three wilderness areas that are within the Okanogan - Wenatchee National Forest the Goat Rocks, Norse Peak, and William 0 Douglas wilderness areas. Visitor use in these wilderness areas is moderate. Table 5-2 summarizes the wilderness areas within the Naches watershed. Table 5-2.

Wildlife The Naches River watershed supports habitat for a variety of wildlife. The U.S. Forest Service Wenatchee National Forest Plan indicates that threatened and endangered species are present in the Naches River watershed, including bald eagles, grizzly bears, spotted owl, and bull trout. The Forest Service strives to maintain the habitat areas for these and other species.

Approximately 32 percent of the watershed area is within the Norse Peak, Goat Rocks, and William O. Douglas Wilderness Areas. Portions of the watershed are owned by the State of Washington, while some of the watershed is privately owned Of the state-owned land in the watershed, roughly 40 percent is managed by DNR, and the other 60 percent is managed by DFW The majority of the state lands are in the lower Naches area, just upstream from the Town of Naches Table 5-3 shows the land ownership for the watershed drainage area that supplies the City's WTP Figure 5-3 provides a geographic representation of land ownership Table 5-3.

The majority of the watershed is a reserved wilderness area or national forest. However, the development that does exist is concentrated along the state highways, which parallel the two major rivers. Therefore, the potential does exist for contamination of the water supply.

This area makes up a portion of the Wenatchee National Forest. Land -uses within the Wenatchee National Forest include recreation, timber production and harvest, and wilderness areas. The Wenatchee National Forest Plan identifies the maintenance of quality water for human use and fish and wildlife needs as a fundamental component of forest management The Plan recognizes that water originating from the forest must be suitable for domestic use with cost effective treatment processes As part of the Wenatchee National Forest Plan, the Forest Service has established the goal to meet or exceed standards set forth in the State's Forest Practice Rules (Title 222 WAC) and related regulations The Forest Practice Rules include restrictions on the application of fertilizers, pesticides, and chemicals on forest lands Sampling of water quality suggests that the Wenatchee National Forest has historically complied with State water quality standards Wildfire Wildfire is common in the Wenatchee National Forest. The Forest Service implements management practices to reduce the risk of wildfire in the watershed. Management practices include forest thinning, prescribed fires, and public outreach to educate visitors about fire prevention In 2013, the U.S. Department of Agriculture and U.S. Department of the Interior established the Western Watershed Enhancement Partnership (WWEP). The WWEP is a federal, local and private partnership that aims to reduce the risks of wildfire to America's water supply in western states. In 2015, under the WWEP, the Forest Service and Bureau of Reclamation began pre -fire forest thinning in areas that drain into Rimrock Reservoir. This will contribute to reduce the risk of wildfire in the watershed that can cause water quality impacts. Future efforts under the WWEP are expected to continue to improve conditions in the watershed. In 2014, the Yakima Valley Fire Adapted Communities Coalition (YVFACC) was formed, comprised of Federal, State, and local agencies and land managers Members include the Forest Service, DNR, DFW, and Yakima County, among others. The YVFACC works to increase and sustain wildfire resiliency in the Yakima Valley. The YVFACC was established to network with regional stakeholders to address wildfire issues In 2015, the YVFACC worked with the Bureau of Land Management and DNR to develop the Yakima County -wide Community Wildfire Protection Plan The Plan provides a description of wildfire risks and mitigation activities in Yakima County Agriculture As indicated in Figure 5-4, the agricultural land in the watershed is concentrated in the lower Naches River watershed, near the Town of Naches, and along Highway 410 paralleling the Naches River. Agricultural land in the Cowiche Creek sub -watershed drains to the area downstream of Yakima's WTP. The Yakima-Tieton Irrigation Canal parallels the Tieton River from downstream of the Tieton Dam area to near the mouth of the Tieton River and provides irrigation supply to farmers within the Yakima-Tieton Irrigation District The Department of Agriculture regulates the application of fertilizer (WAC 16-200) and pesticides (WAC 16-228) on farmlands. Water quality analysis results for the City's raw water supply have to date shown no indication of volatile organics, synthetic organic compounds, or pesticide problems. Potential contamination from accidental/intentional introduction of agricultural or other hazardous chemicals into the Naches River could occur However, runoff from the small- scale agricultural activities in the watershed would likely be diluted before reaching the WTP intake and is therefore unlikely to threaten municipal water quality If a hazardous chemical 5-12 1 July 2017 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan spill were to occur, the risk and response to these conditions would be similar to the actions necessary for a transportation chemical spill. The City of Yakima has established emergency response measures to respond if a source water contamination event were to occur. Emergency response measures are included in the City's Emergency Operations Guidelines (Appendix R). Livestock Grazing The 2006 Natural Resources Conservation Service Naches Watershed, Rapid Watershed Assessment identifies rangelands within the Naches River watershed on lands managed by DNR. DNR manages public land leases in the Naches River watershed. These public land leases set restrictions on livestock management to minimize impacts to water quality. Historically, there have not been any water quality issues associated with livestock in the watershed Livestock grazing in the Naches River watershed is limited such that little or no contaminants are expected in the future due to livestock operations Municipal and Industrial Wastewater The Town of Naches WWTP discharges treated effluent into the Naches River about 3 miles upstream of the City of Yakima WTP. Figure 5-3 shows the location of the Town of Naches with respect to the City of Yakima's WTP In 2007, the Town of Naches upgraded their WWTP facility to improve the quality of effluent released to the Naches River The WWTP Is a secondary treatment facility operating between a 90 and 95 percent biochemical oxygen demand and total suspended solids removal efficiency The City of Yakima has established emergency response measures to respond if a source water contamination event were to occur due to failure of the Naches' WWTP. Emergency response measures are included in the City's Emergency Operations Guidelines (Appendix R). The City maintains emergency contact information with the Town of Naches in the event of a contamination event. Septic Tanks The Town of Naches is sewered. Wastewater disposal outside the city limits is by septic tanks and drain fields In addition, septic systems are probably present in some of the approximately 40 camping areas and resorts that are located in the watershed The largest concentrations of septic systems are probably in the small communities of Nile, Squaw Rock, Pinecliff, Gold Creek, Silver Beach, and Rimrock The urban and built-up areas within the Naches River watershed are, therefore, limited and are concentrated in the lower -watershed In 2015, Yakima County adopted the Title 19: Unified Land Development Code This code is intended to protect public health and safety by establishing rules for sewer and septic systems. This code also increases Yakima Health District enforcement of satellite sewer systems and individual septic systems, thereby reducing the risk of satellite sewer or septic system failure. Residential and Commercial Land Uses The total population in the watershed above the Naches-Tieton confluence is approximately 4,584 persons, according to the 2010 US Census data for Census Tract 30.01. This population number includes some areas that drain downstream of Yakima's WTP. The average population density above the Naches-Tieton confluence is about 4 persons per square mile. An additional 10,238 people live in the area adjacent the lower Naches River drainage between the confluence and Selah (not including Selah) (Census tracts 29 and 30.02). This population number includes the Cowiche Creek sub -watershed area which drains to the area downstream of Yakima's WTP. The equivalent gross population density for this area is about 110 people per square mile. According to the Washington State Office of July 2017 1 5-13 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan Financial Management population estimates for Yakima County, there was little or no growth between 2010 and 2014 in the communities and unincorporated areas above the City's WTP. This growth trend is expected to continue. Roads and Transportation Corridors There are two state highways that traverse the watershed from east to west Highway 12 and Highway 410. Highway 410 parallels the Naches and American Rivers across the entire watershed. Highway 12 parallels the Tieton River to Rimrock Reservoir and continues parallel to Clear Creek until it exits the western boundary of the watershed. There are also numerous Forest Service roads, county roads, and other secondary roads traversing the watershed. Vehicle use and transportation of oil or other chemicals along these highways could result in an oil or hazardous material spill along the Naches or Tieton Rivers The City is a partner in the Yakima Area Geographic Response Plan (GRP) which provides a response strategy for protecting sensitive resources in the event of an oil spill The Yakima Area GRP and City - specific actions are described further in Section 5 3 4 Recreation Fishing is a primary form of recreation in the Naches watershed The American, Bumping, Little Naches, and Tieton Rivers, Rattlesnake Creek, and Bumping and Rimrock Reservoirs all contain various species of trout and salmonids The lakes also support Kokanee salmon Dispersed recreational uses such as backpacking, hiking, hunting, fishing, skiing, snow- mobiling, off-road vehicle travel, camping, rafting, and kayaking are all common in the Yakima River basin. Most of the uses are present to some degree in the Naches River watershed. There are no state or federal parks within the watershed, but there are approximately 40 recreation sites in the watershed, most of which are managed by the Forest Service. The primary water quality concerns associated with recreation are nitrates and bacteriological contamination from improper disposal of human waste. Water quality analysis results for the City's raw water supply show that nitrate and bacteriological levels are well within the treatment plant's operating range for effective removal Mining Small-scale mining is present in the watershed For example, Copper Mining Co mines silver, copper, gold, and tungsten south of Bumping and Rimrock Reservoirs Although lead, zinc, and uranium has been detected, no economic deposits have been discovered In addition, Horseshoe Bend Quarry is located along Highway 410, adjacent to the Naches River Runoff from to small-scale mining activities in the watershed would likely be diluted before reaching the WTP intake and is therefore unlikely to threaten municipal water quality Landslides There is a potential for landslides in the Naches River watershed that can increase water turbidity In October 2009, a landslide occurred near the Community of Nile that submerged approximately a half -mile of State Route 410 and temporarily redirected flows in the Naches River Although this event resulted in increased turbidity in the Naches River, the City was still able to manage turbidity levels and continue operating the WTP As part of the Forest Practice Rules (Title 222 WAC), Ecology and DNR have established buffer zones around streams/waterways to protect from landslide and erosion 5-14 1 July 2017 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan Volcanos There is a potential for volcanic ashfall in the Yakima area In May 1980, Mount St Helens erupted resulting in about 3 inches of ash to fall on the Yakima area within the first 24 -hours A total of approximately 5 inches of ash fell on the Yakima area Following the eruption, the City shut down the WTP for several days until turbidity and pH returned to manageable levels. During the WTP shut down, the City switched to groundwater supplies. Potential Surface Water Contaminants Table 5-5 summarizes land uses in the watershed and indicates the possible contaminants from each type of land use. This table was adapted from Effective Watershed Management for Surface Water Supplies, American Water Works Association Research Foundation (AWWARF), 1991 Appendix T includes a list of active Ecology regulated sites/facilities in the Naches River watershed (WRIA 38) that could be potential sources of surface water contamination. This is a consolidated list that includes all active potential contamination sites in WRIA 38 identified under the following Ecology programs: • Air Quality Program • Hazardous Waste Program • Shoreline and Environmental Assessment Program • Water 2 Resources Program • Spill Prevention, Preparedness and Response Program • Toxics Cleanup Program • Water Quality Program • Water Resources Program • Nuclear Waste Program • Industrial Program • Environmental Assessment Program July 2017 1 5-15 Chapter 5 - Source Water Protection City of Yakima 2017 Water System Plan Table 5-5.

July 2017 1 5-16 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan Priority Water Quality Threats Based on the land uses within the Naches Watershed and the associated potential contaminants, the City considered the water quality threats that pose a plausible risk to the City's surface water supply. The City broke these threats into two tiers. Tier 1 threats are those that pose the greatest risk to water supply, and are therefore a primary priority for City water contamination planning and response. Tier 2 threats are those that pose a lesser risk to water supply, but that the City still considers for water contamination planning and response. Table 5-6 summarizes the Tier 1 and Tier 2 water quality threats to surface water supply in the Naches River watershed. Table 5-6. Priority Water Quality Threats to Surface Water Supply Tier 1 Water Quality Threats Wildfire producing increased water turbidity and pH Landslides producing increased water turbidity Malfunction of the Town of Naches WWTP resulting in water contamination Hazardous material spills from transportation accidents, resulting in water contamination Tier 2 Water Quality Threats Widespread septic tank failure resulting in water contamin Road water runoff containing gasoline and other chemicals I New residential, commercialjndustrial developments Logging activities causing turbidity ■ Largstocausing creased water turbidity Agriculture or forest fertilizer and chemical application Livest Recreation activities (off-road vehicles, boating, campsite waste, etc ) raakima-Tieton Irrigation District canal modifications or construction activities Volcanic eruption from Cascade Range volcanoes causing high turbidity from ashfall 5.3.4 City of Yakima Watershed Control Measures The vast majority of the City of Yakima surface water supply watershed is publicly owned. As pointed out in the Department of Health Sanitary Survey report dated April 22, 2002, the City does not have jurisdiction over activities in the watershed which include; recreation, timber harvesting, vehicle traffic on two major transportation corridors, Town of Naches WWTP operations, and irrigation water storage and delivery systems including Rimrock and Bumping Reservoirs. As stated in the Sanitary Survey report, the City is "doing the best that they can under the current ownership and control." The most effective approach available to the City under these circumstances is to work closely with the other federal, state, and county agencies with jurisdiction over activities in the watershed to make sure that the policies and decisions affecting watershed management and water quality fully consider the potential impacts on the City's water supply As such, the City established the following Watershed Control Program goals July 2017 1 5-17 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan 1. Where feasible, work to minimize watershed conditions or incidents that compromise water quality for municipal water supply. 2 Where feasible, work with partners in the watershed to receive rapid notifications if a contamination incident occurs, thereby improving the City's ability to response quickly and/or switch to groundwater supplies To this end, the City has established City -specific Watershed Control Program strategies for maintaining water quality in the Naches River watershed For each strategy, the City has identified measures that the City can take to help maintain water quality in the watershed Where applicable, City measures build on existing watershed protection efforts in the watershed 5-18 1 July 2017 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan Table 5-7. City of Yakima Watershed Control Program Strategies and Measures Strategy Measures 1 Establish communication strategies with other entities in the watershed to keep informed about potential threats and provide input to make sure that the policies and decisions affecting watershed management and water quality fully consider the potential impacts on the City's water supply 1 Attend YVFACC meetings to engage with other stakeholders in the watershed on wildfire management and watershed health topics Periodically present at YVFACC meetings to educate members about water quality considerations for municipal water supply 2 Engage with Yakima County, State agencies, and the Corp of Engineers to receive notices of proposed land use permit applications that might adversely impact the water quality of municipal water supplies In particular, the City will monitor applications for activities upstream of the WTP that require a Clean Water Act Section 404 Permit, Section 401 Clean Water Certification, and/or a Hydraulic Project Approval 3 Communicate with the Town of Naches WWTP operators to ensure contact information and emergency response measures are maintained This can be scheduled to coincide with the City's WHPP notifications distributed every two years 4 Distribute notifications to Yakima County, the Department of Transportation, and land management agencies in the Naches River watershed to educate these entities about the impact that activities in the watershed have on water quality for municipal water supply This can be scheduled to coincide with the City's WHPP notifications distributed every two years 2 Maintain emergency water contamination response procedures, including coordination with large land owners in the watershed 1 ri Update the Emergency Operations Guidelines (Appendix R) and Operation and Maintenance Manual annually to ensure emergency contacts and other information remains up-to-date Activate Emergency Operations Guidelines as needed 2 Work with Ecology to maintain a Yakima Area Geographic Response Plan and implement spill response actions at vulnerable sites as needed 3 Continue to develop ASR and groundwater resources as back-up supplies that can serve as a resource during short-term disruption of the surface water supply 3 Participate in efforts to protect water quality in the watershed 1 Collaborate with partners in the watershed on projects that protect water quality in the Naches River watershed (e g projects through the Integrated Plan, Washington Resource Conservation & Development Council, or Salmon Recovery Funding Board) For example, the City can provide letters of support for projects in the watershed that have a water quality protection component 4 Continue to maintain inventory of potential water quality impairments and opportunities to reduce contamination risks 1 Continue to maintain inventory of entities with potential contaminant sources and regularly engage in outreach to these entities This can be scheduled to coincide with the City's WHPP inventory update every two years or as part of regular updates to the Emergency Operations Guidelines 2 Work with Yakima County to maintain shoreline protections such as aquatic buffers, erosion and sediment control, open space development, stormwater control operation and maintenance, and post construction controls, and enforce restrictions on illicit discharges July 2017 1 5-19 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan Yakima Area Geographic Response Plan During the development of this Water System Plan, the Washington State Department of Ecology was in the process of establishing a Geographic Response Plan (GRP) for the Yakima area GRPs are annexes to the Northwest Area Contingency Plan which guides response to oil spills in Washington, Oregon, and Idaho Each GRP is prepared for a specific area and includes response strategies tailored to a particular waterway at risk of damage from an oil spill. GRPs help to coordinate response efforts by impacted entities, and Federal and State agencies. They include initial action plans for responders to take in the event of an oil spill, including contacting entities at risk of contamination and deploying oil containment booms. The City of Yakima is involved in the development of the Yakima Area GRP The Yakima Area GRP will include 10 5 miles of the Naches River above the confluence with the Yakima River This GRP does not include the Tieton River since Ecology has determined that there are no significant spill risks along the Tieton River As part of this effort, the City provided Ecology with information on vulnerable surface water supply facilities, City -specific response measures, and emergency contact information The City identified the WTP intake structure on the Naches River as the key vulnerable facility, since it is vital for providing potable water supply to City of Yakima citizens. If an oil spill event occurred upstream of the WTP intake structure, then the City would respond by closing the WTP intake head gates and switching to groundwater resources to maintain water supply. If necessary, the City would also assist Ecology in containing any contaminants that reached the intake channel. Aquifer Storage and Recovery The City currently uses its groundwater supply system as a backup to supplement surface water supplies when needed In January 2017, Ecology issued a final Reservoir Permit authorizing the City to conduct ASR activities The City's ASR program would contribute to augmenting its ground water supply The City's ASR program would contribute to supplementing existing water supplies and be a valuable resource if a contamination event in the Naches River watershed occurred that required the WTP to be shut down for an extended period Chapter 4, Conservation and Water Resources, describes the use of ASR wells to improve water supply reliability. Monitoring Water Quality Conditions The Naches River watershed encompasses a large area and a wide range of land uses and land ownership. Several agencies including the Bureau of Reclamation, the U.S. Geologic Survey, the Forest Service, and Ecology maintain ongoing water quality monitoring programs within the Naches River watershed. The City of Yakima Water/Irrigation Division does not have the staff or the resources to conduct routine monitoring within the watershed. However, the City monitors raw water quality of the surface water supply and adjusts water system operations accordingly Understanding conditions in the Naches River is vital to the operation of the WTP. In the spring of 2004, WTP staff installed a new HF scientific turbidimeter at the WTP intake structure to monitor raw water turbidity from the Naches River. The turbidimeter allows WTP operators to identify and respond quickly to changes in turbidity levels of raw water quality. The City also monitors the Bureau of Reclamation's river operations above the WTP Understanding flow conditions in the Naches River is important for WTP operation The City regularly attends the Bureau of Reclamation's monthly planning meetings to discuss river operations below Bumping Lake and Rimrock Reservoirs The City also monitors the Bureau of Reclamation's daily river operations reports In addition, the City is on the Bureau of Reclamation's notification list to be informed of changes to river operations 5-20 1 July 2017 Chapter 5 — Source Water Protection City of Yakima 2017 Water System Plan The City's WTP operation staff also monitors the following weather prediction and forecasts sites to inform decisions about WTP operation. • The National Oceanic and Atmospheric Administration (NOAA) - Advanced Hydrologic Prediction • NOAA — National Weather Service for 3 Miles South by Southeast of Naches, WA. • US Bureau of Reclamation Yakima Project System Status Report The WTP operators monitor these sites year-round, especially during spring runoff periods and late-fall/early-winter storm periods. In addition to monitoring these websites, the City also subscribes to SunComm (Yakima 911 system) to receive alerts about weather storm warnings. These river condition monitoring activities and general operational observations aid the WTP operators to plan for and respond to rising turbidity levels and potential flood events that could impact water quality at the WTP. 5.3.5 System Operations and Emergency Provisions In addition to the actions described above, emergency provisions and response measures in the event of contamination event are documented in the City's Emergency Operations Guidelines (Appendix R). Section 3.3 of this Water System Plan summarizes the City's water quality considerations, monitoring program, and compliance with applicable water quality regulations.

This certification level is designated by the State of Washington due to plant size and complexity. 6.1.5 Water Distribution Supervisor The operation of the distribution system is under the direction of the Water Distribution Supervisor. This position oversees staff who perform installation of new services, fire hydrants, and fire services; preventive maintenance, repairs, and replacement of pipelines, PRVs, and meters; and testing of cross -connection control devices and large valves. Meter reading is performed by utility billing staff and is, therefore, not included within the responsibilities of water distribution staff. 6.1.6 Waterworks Crewleaders and Waterworks Specialist I and II Eleven positions within the water distribution group are classified as Waterworks Crewleaders or Waterworks Specialists I or II, as follows: • Waterworks Crewleaders are crew leaders for distribution system operations and maintenance. • Waterworks Specialists II are primarily equipment operators with general labor duties. • Waterworks Specialists I are general laborers. 6.1.7 Water Device Technicians The distribution group includes one Crewleader and two device technicians who are primarily responsible for cross -connection control, installation of the automated meter reading system and repair of large meters 6.2 Operator Certification Pursuant to Chapter 246-292 WAC, the City is required to have certified operators Certified personnel are required for positions that are in direct charge of a public water system or major segments of the system and are responsible for monitoring or improving water quality DOH requires every community public water system to maintain at least one certified operator on staff at or above the classification level for that community The City of Yakima water system is classified as Level 4 On -duty operators must maintain a certification level not more than one level lower than the classification of the community water system The Naches River WTP is classified as Level 4 based on its size and complexity. Therefore, the WTP must retain at least one level 4 operator, and all operators must be certified at level 3 or higher. Positions with operator certifications below level 3 are not considered "operators" for the WTP but are regular supporting staff. July 2017 1 6-3 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan State regulatory language establishes various organizational positions for personnel working for the City Water Division. The following positions are occupied by City personnel: • Water Distribution Manager (WDM) • Water Treatment Plant Operator (VVTPO) • Cross Connection Specialist (CCS) • Backflow Assembly Tester (BAT) These positions are filled by personnel meeting State mandated requirements. 6.3 System Overview The major water system components that are operated by the water utility are the Naches River Intake and WTP, four wells (Kiwanis Park, Airport, Kissel Park, and Gardner Park), five storage reservoirs, four pump stations, pressure -reducing valves (PRVs), and distribution system pipelines. The locations of the components of the distribution system are shown in Figures 1-2 and 3-1. Descriptions of these components and how they operate together as part of the system are provided in Chapter 1 and Chapter 3. The nonpotable irrigation system that serves many parts of the City with water for irrigation is not discussed in this plan. There are two emergency interties between the Nob Hill Water Association and the City of Yakima distribution systems A description of these interties is provided in Chapter 1 6.4 Operation and Maintenance of Major System Components Summary descriptions of major system components and functions and the procedures used to operate the major components of the water supply and treatment system are provided below For detailed descriptions of the systems and operational procedures refer to the Naches River Water Treatment Plant Operation and Maintenance Manual 6.4.1 Naches River Water Treatment Plant Raw Water Intake Raw water is supplied to the WTP by a raw water pipeline connected to intake facilities adjacent to the Naches River, located approximately 3,500 feet upstream of the WTP facilities The intake consists of a series of five flat -panel screens designed to achieve fish screening criteria for endangered species protection The screens are cleaned via air wash supplied to each screen by an air piping manifold with a series of orifices located immediately behind each screen The screen structure is separated from the river by a concrete wall and an auxiliary intake gate/headwall structure located 1,000 feet upstream of the screens Water is supplied to the screens through gates in the headwall to allow water from the river to flow into the facilities Water discharges from the facilities over an Obermeyer weir that functions to maintain the water surface above the top of screens. 6-4 1 July 2017 Primary Failure Consequences Table 6-2.

Critical = Failure causes problems but plant operation is possible. Vital = Failure requires plant shutdown. Flash Mix Proper feed and mixing of chemicals is of fundamental importance for a properly working water treatment facility The flash mix process imparts energy to the water to ensure complete mixing of chemicals A pump diffusion type flash mix is utilized at the WTP A side stream of water is drawn from the raw water pipeline and pumped back into the pipeline in the opposite direction of the main flow, thereby creating a turbulent mixing zone. Chemicals that can be injected at flash mix include the following: • Primary Coagulant (Aluminium Chlorohydrate (ACH) or Alum); • Sodium Hypochlorite; July 2017 1 6-5 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan • Coagulant Aid Polymer, • Caustic Soda The Flash Mix components and function are summarized in Table 6-3 Table 6-3.

Alum and coagulant aid polymer react with natural suspended solids to create "floc" particles The "floc" particles settle in the contact basins and are removed in the filters No mechanical flocculation energy is added in the contact basins • Disinfection. Prechlorination at the flash mix basin provides additional contact time before the final application of chlorine Longer chlorine contact time improves disinfection and increases the potential of disinfection byproduct formation • Taste and Odor Reduction. When powdered activated carbon (PAC) is used, the Contact Basins allow PAC to adsorb taste and odor compounds before reaching the filters, where the PAC is removed The addition of PAC can affect the disinfection process by adsorbing chlorine • Solids Removal. The basins remove sand and other heavy particulate matter by gravity settling during episodes of high raw water turbidity. This protects the filters from shortened filter runs that would result from excessive solids loading onto the filters. 6-6 1 July 2017 Primary Failure Consequences Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan The Contact and Sedimentation components and function are summarized in Table 6-4.

This means that contact basins upstream of the filters provide time for the development of filterable particles following coagulation There is no flocculation and minimal sedimentation processes upstream of the filters to condition or remove particles The WTP has four filters with dual media, consisting of a layer of anthracite coal on top of a layer of silica sand. The media is supported by plastic tri -lateral filter underdrains. The filter media, underdrains, troughs, and surface wash system were replaced in 2005. The filter component and failure criteria are summarized in Table 6-5. Table 6-5.

The WTP utilizes chlorine to disinfect the water. Section 11 of the Naches River Water Treatment Plant Operation and Maintenance Manual contains a discussion of the chlorine storage and delivery system This section focuses on measurement and reporting of disinfection. Disinfection at the WTP Is achieved in two steps, "Sequence 1" and "Sequence 2 " Sequence 1 takes place when the water is in the basins or pipelines at the WTP Sequence 2 takes place in the pipeline between the clearwell and the Gleed Pump Station The total level of disinfection achieved is the sum of disinfection achieved in Sequence 1 and Sequence 2 The Surface Water Treatment Rule (SWTR) governs the required removal and inactivation of microbial pathogens. The minimum performance requirements presented below are based upon the classification of the WTP as a direct filtration facility, that is, without conventional flocculation and sedimentation processes for solids removal upstream of the filters. Giardia cyst removal and inactivation requirement 3 -log (99 9%) • 2 -log (99%) removal via filtration • 1 -log (90%) inactivation via disinfection Virus removal and inactivation requirement 4 -log (99 99%) • 3 -log (99 9%) removal via filtration • 1 -log (90%) inactivation via disinfection The requirement for both removal and disinfection of microorganisms provides multiple barriers against contamination of the public water supply CT Control Valves The hydraulic gradient originally was such that the 48 inch pipeline did not become full of water under normal circumstances until somewhere between Eschbach Road and the community of Gleed In 1998 a set of control valves was installed in the 48 inch main next to the Gleed Pump Station These valves are automatically monitored and controlled from the WTP so that the pipeline between Gleed and the plant remains full and therefore provides the required CT time. If the CT control valves were to fail, one of the operators would drive to Gleed adjust valves by hand and observe the pressure reading locally to ensure the proper valve settings. Residuals Handling Facilities The water treatment process removes particles from the water through some settling in the contact basins and capture in the filter media The residuals handling facility consists of lagoons with individually actuated inlets, recycle pumps and piping, and filter -to -waste pumps and piping Pumps are located in the pump control building constructed in 2014, and located west of the filters Mechanical components of the system include the pumps and valves, while structural components consist of the lagoons and pipe To aid in settling and drying of solids produced during the backwash process, an anionic polymer is added to the backwash waste stream with the use of a Fluid Dynamics polymer mixing system. A list of specific components and their associated functions is provided in Table 6-6. July 2017 1 6-9 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan Table 6-6.

Provided taste and odor compounds are present. 6.4.2 Transmission Mains Description The transmission mains are pre -tensioned concrete cylinder pipe and range in size from 54 -inch to 30 -inch with lengths as follows 54 -inch = 3,500 LF 48 -inch = 45,100 LF 30 -inch = 3,300 LF These mains were installed during the period of 1968-1972 Water flows through these pipelines utilizing the force of gravity only No pumps are required to aid the movement of water The 54 -inch transmission main moves water from the Naches River Raw Water Intake Structure to the WTP The 48 -inch transmission main moves water from the WTP to the City of Yakima's domestic water distribution system July 2017 1 6-11 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan The 30 -inch transmission main moves water between the equalizing reservoir at 40th Avenue and Englewood (1St Level Reservoir) and the 48 -inch transmission main. Transmission Main Operating Modes and Alternatives The function of the transmission facilities is to transport large quantities of water from the source to the point of treatment and disinfection (WTP) and from this point to the City's distribution system. The 48 -inch transmission main has outlets installed along its length at intervals of approximately every 1,000 feet Connections to this main can be accomplished through the use of an existing outlet or by direct tap The 48 -inch pipeline follows Highway SR -12 from the WTP about 5 miles south to where it crosses the Naches River. In 2011, two 36 -inch valves were installed on the transmission pipe, one on each side of the Naches River crossing. At each valve is a 24 - inch tee and valve assembly. In the event of the transmission pipe being damaged at the river crossing, the tees and valves allow for the installation of an emergency bypass of the river crossing by utilizing the existing abandoned railroad bridge (now converted to non -motorized, multi -use path) adjacent to the transmission main's alignment. After the river crossing, the main continues to 40th Avenue where it turns south on 40th Avenue to Powerhouse Road. The main turns and runs along Powerhouse Road to Englewood Avenue at the intersection of Powerhouse Road and Englewood Avenue. At the intersection of 40th Avenue and Englewood Avenue is the 1st Level Reservoir. This reservoir is connected to the 48 -inch pipeline via a 30 -inch pipeline running along Englewood Avenue. After the Powerhouse Road and Englewood Avenue intersection, the 48 -inch main continues east along Englewood Avenue to the intersection of 16th Avenue and Cherry Avenue where the 48 -inch pipeline terminates with several distribution pipelines radiating out from this terminus. Should the transmission facility cease to function between the source and 40th Avenue, then this loss will be treated as a loss of supply Should the break occur between 40th Avenue and 16th Avenue, then the damaged section will need to be isolated until repairs or replacement can be accomplished. Detailed procedures and alternatives for handling a transmission line failure are included in the Emergency Operations Guidelines (Appendix R). 6.4.3 Distribution and Storage Systems The City's distribution system is adjacent to several water systems, but the only interties are with the Nob Hill Water Association Nob Hill Water interties are located in the 3rd Level pressure zone at the intersection of 56th Avenue and Lincoln Avenue and within the 1st Level pressure zone at South 32nd Ave. and Ahtanum Road. The distribution pipelines are 4 to 24 inches in diameter The pipe materials are mainly cast iron, with ductile iron being used since the early 1970's There are several steel pipelines and many unlined cast iron pipelines remaining in the system The City's existing storage capacity is 32 million gallons (MG) distributed among five reservoirs within the three pressure zones. Each pressure zone has an established hydraulic elevation. This elevation is maintained by the distribution reservoir(s) located in each of the pressure zones. Information on the reservoir sizes, materials of construction, and elevations are provided in Chapter 1. 6-12 1 July 2017 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan Itszodi Distribution and Storage Systems Operating Modes and Alternatives The function of the distribution system Is to deliver potable water to the service connections and fire hydrants The function of the storage reservoirs is to provide: 1) standby water storage for emergencies and short-term interruptions of source of supply; 2) additional source of water for fire protection purposes, 3) equalizing water for changes in water demands within the system Distribution pipelines branch off from the transmission mains, conveying water to the three pressure zones — 1st2nd and 3rd Levels. Gravity alone provides adequate pressure to serve water to the 1st Level zone. Booster pump stations push the water up to the reservoirs in the 2nd and 3rd Level zones, and pressure -reducing valves (PRV's) regulate water flows back from the 3rd to 2nd and 2nd to 1st Level zones when necessary. Normally closed valves and three PRV stations may be operated to move water from the 3rd Level zone to the 2nd Level zone. Conversely, portions of the 3rd Level zone could be served (at lower pressure) from the 2nd Level zone through operation of these normally closed valves and existing check valves. The 1st Level Reservoir is utilized as an equalizing reservoir for the entire water system The flow at the WTP is adjusted based upon levels in this reservoir. Any water not consumed by the 1st Level zone through customer demand, or by pumping to the 2nd and 3rd Level zones, is stored here. Should the distribution system cease to function in specific areas, these areas may be isolated by closing valves to sections as needed based on the distribution grid system in the affected area Should the entire distribution system fail to provide its function, then water would necessarily have to be hand carried or transported by vehicles. No fire protection would be available from the system. Fire Department tankers would have to be utilized for fighting fires. Potable water would need to be made available at distribution points throughout the system. The Yakima Firing Center, the National Guard, and private carriers may be pressed into service in an emergency Fire stations, City parks, and other City property make good points of distribution of potable water City residents would be notified of these distribution points and instructed to bring containers to receive their allotment of water The source of water for supplying the distribution points could be the Kiwanis Park and Airport artesian wells if flowing. Additionally, potable water could be purchased from any adjacent purveyors that would still have a safe plentiful supply. Should the storage reservoirs cease to function, the system's ability to meet all demands would become undependable Some fire fighting capability might be retained, but not to normal standards The interties with Nob Hill Water Association could be utilized to place their reservoirs into shared operation The reservoirs could be isolated and water supply pumped directly into the system from the wells or by the gravity from the WTP The 48 -inch transmission main could act as a reservoir during an emergency During extended emergencies portable storage reservoirs or temporary reservoirs could be utilized to accomplish the same function as a storage reservoir Detailed procedures and alternatives for handling a distribution and storage system failure are included in the Emergency Operations Guidelines (Appendix R). July 2017 1 6-13 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan Distribution and Storage System Routine Operation and Maintenance Routine operation of the distribution system consists of operating line valves and manu- ally opening and closing interties (when needed). Hydrants are tested annually. The levels in the five storage reservoirs are controlled by the SCADA system. The levels in the system's reservoirs are continuously monitored by telemetry and recorded on 7 -day charts and in the history files of the City's computer system. 6.4.4 Booster Pump Stations There are four booster pump stations: 3rd Level, 40th Avenue, Gleed, and Stone Church. Information on these pump stations (location, pumps, elevation) are provided in Chapter 1 Booster Pump Stations Operating Modes and Alternatives The booster pump stations provide water to the 2nd and 3rd Level zones, as shown in the hydraulic profile. The 40th Avenue and Stone Church pumps are operated in a variety of lead lag positions depending on the demand and the season. The difference in water demands is due to an irrigation demand in the 2nd and 3rd Level zones. These pumps are controlled by the 2nd Level zone's two reservoir levels through the radio telemetry system. The 3rd Level pumping station is only capable of operating one of the 125 HP pumps at a time This is due to the size of the electrical service available when the facility was constructed The two 125 HP pumps are alternated with one placed in a standby role, while the other is being used and with the 40 HP pump placed in the lag position The smaller 40 HP pump is placed in the lead during low demand times This station's pumps are controlled by the water levels in the 3rd Level zone's two reservoirs through the radio telemetry system The Gleed pumping station is operated by utilizing the two 5 HP pumps to meet domestic water demands and the 125 HP pump for fire flow demands This station's pumps are controlled by pressure sensing controls and a hydropneumatic tank • At 55 psi the lead pump will start and run until pressure builds to 75 psi. • Should the pressure continue to drop after the lead pump starts then at 50 psi the backup pump starts. This pump shuts off at 70 psi. • Should the first two pumps be unable to supply sufficient pressure, at 30 psi the 125 HP pump will start and run until it has run at 90 psi for 12 minutes before shutting off • A pressure relief valve is located in the manifold system and allows the bypass of water back into the 48 inch transmission main of any water in excess of 100 psi Should the 40th Avenue and Stone Church pump stations cease to function, the stored supply in the 2nd Level Reservoirs may be utilized for a limited time to supply demand. If additional water supply is needed to meet the demands, the Nob Hill Water Association may also be contacted to furnish a source of water through the emergency intertie in the 2nd and 3rd Level zones. Should the 40th Avenue or Stone Church Pump Stations cease to function because of an electrical power outage, a portable electrical generator might be used to restore electrical power to the 40th Avenue Pump Station Chapter 3 identifies an improvement project to install a new VFD for the largest pump at the station to provide for improved system operation for the 2nd Level zone should the 2nd Level Reservoirs and 40th Avenue Pump Station become isolated from the system due to a main break or other system failure 6-14 1 July 2017 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan Should the 3rd Level Pump Station cease to function, the available supply in the 3rd Level Reservoirs may be utilized for a limited time to supply demand. If additional water supply is needed to meet demands, the Nob Hill Water Association may be contacted to furnish a source of water through the emergency intertie at 56th Avenue and Lincoln Avenue. Should the 3rd Level Pump Station cease to function because of an electrical power outage, the electrical generator should be used to restore electrical power to the site Should the Gleed Pump Station cease to function, the customers are without a water supply at adequate pressure (greater than 30 psi). However, as long as the 1St Level Reservoir is capable of maintaining at least a minimum level, there is a positive pressure at Gleed. Currently, there are less than thirty customers served by this pump station and one school (school will be decommissioned in 2017). Storage will need to be installed before more customers can be added to the Gleed system. Water supply for domestic purposes would continue to be available at low pressure (10-15 psi). A local carrier with a food grade tanker may be filled with water and connected to the fire hydrant near the Naches Primary School to supply the Gleed System. The Gleed Fire Department will be notified immediately if the station is to be out of service for any length of time. This rural department has the capability of fighting fires without adequate water supplies available close at hand through use of tanker trucks and can dispatch additional tanker units if necessary Detailed procedures and alternatives for handling a booster pump system failure are included in the Emergency Operations Guidelines (Appendix R). Booster Pump Station Routine Operation and Maintenance The four pump stations are controlled by the SCADA system, but are visited three times per week to check building temperature and pump operation 6.4.5 Pressure Reducing Valve (PRV) Stations The PRV stations are listed in Table 1-3 in Chapter 1, indicating the location, size, pressure settings, the zone that is served and some additional information PRV Operating Modes and Alternatives Control of water flow between the 2nd and 1st Level pressure zones is provided by the PRV's located throughout the distribution system These control valves are set to open and close at various hydraulic elevations depending on the intended purpose of the valve (continual supply or emergency only) The normal use of the City's PRV's is to provide additional water flow for emergency purposes The reduction of pressure in the 1St Level zone under emergency conditions because of a fire flow or other large water demand will cause the hydraulic elevation to decrease This reduction in hydraulic elevation will cause the normally closed hydraulically actuated valves to open and provide additional flow into the 1St Level zone Should the PRV stations cease to function, the valves may be manually operated either open or closed. The effects of the PRV stations having failed are 1) Water movement between zones which will result in losses and increases in water pressure in the distribution system, if failure is in the open position 2) Inadequate water flows during an emergency or other high demand situations, should the valve fail in the closed position Detailed procedures and alternatives for handling a PRV failure are included in the Emergency Operations Guidelines (Appendix R) July 2017 1 6-15 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan PRV Routine Maintenance The PRVs are checked and tested on a quarterly basis 6.4.6 Wells The four wells are visited at least twice each day when in operation, but are also moni- tored by the SCADA System Operational procedures include checking the chlorination equipment, fluoride equipment (only installed at Gardner Park Well), reading the flowmeter, and checking the building's temperature, motor amperage, well drawdown, and the hour meters on the motors Currently, the wells are started and stopped locally Additional information regarding procedures and alternatives for well operation in the event of a loss of supply or water shortage are included in the Emergency Operations Guidelines (Appendix R). Two of the wells, Kissel Park and Gardner Park, are used in ASR activities where water is both injected and recovered from the aquifer. Standard operating procedures regarding ASR activities are included in Appendix Q. 6.4.7 Preventive Maintenance Program Preventive maintenance consists of regularly servicing pumps and motors, exercising valves and hydrants, cleaning reservoirs, and flushing dead-end lines and other pipelines. These activities are performed on a priority basis, with service for pumps, motors, and meters being the highest priority. The City currently implements the Cayenta maintenance management system The system includes information about all of the City's facilities and equipment and is used to automate the existing preventive maintenance program Cayenta consists of a number of modules that track and control purchasing, budgeting, and maintenance. A complete description of the Cayenta modules and their components is included in Section 6.11 of this Water System Plan Update. 6.4.8 Chemicals, Equipment, and Supplies The utility maintains an inventory of equipment, such as vehicles, portable pumps, and backhoes, for servicing the water system The utility also keeps a stock of regularly used supplies and chemicals In addition to the materials and supplies maintained at the service yard, the utility maintains three completely equipped service trucks with the tools and equipment normally required for system operation and maintenance Table 6-8 and Table 6-9 list the equipment and materials, respectively, which are maintained by the utility.

Each month, the State receives water quality data from the WTP and private/state labs contracted by the City of Yakima. Water quality standards enacted by the State are at least as stringent as federal mandated standards. State and federal regulations provide instructions regarding sample collection and analysis methods. Water quality monitoring and sample collection at the WTP is conducted for process control (Table 6-11) as well as regulatory reporting requirements 6-18 1 July 2017 ILnished waterjLGleed Pump Station Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan (see Chapter 3). All process control parameters are monitored using on-line instruments tied into the SCADA system. The requirements for development of inorganic monitoring plans are described in WAC 246-290-300 (30 Organic chemical monitoring plan requirements are described in WAC 246-290-300 (7e) Copies of the current monitoring plans are included in Appendix sections as listed below Appendix M Coliform Monitoring Plan Appendix J Inorganic Chemicals Monitoring Plan Appendix K Organic Chemicals Monitoring Plan Appendix L Stage 2 Disinfectant/Disinfectant By -Products Monitoring Plan Appendix N Continuous and Miscellaneous Monitoring Plan Table 6-11.

Sample tap located at the coagulation control center. 5. Sample tap located at the water quality lab sink. The Gleed pump station, downstream of the water treatment plant, contains automated instrumentation to measure pH, temperature, pressure, free chlorine, and fluoride. These data are transmitted to the WTP via telemetry. "CT" calculations for the finished water are made based upon the water quality data collected at Gleed pump station and as described further in Section 9 of the Naches River Water Treatment Plant Operation and Maintenance Manual on "Disinfection" There are no service connections between the plant and Gleed pump station. By the time finished water has reached Gleed pump station, chemicals have been thoroughly mixed so that an accurate measurement of residual chlorine and fluoride can be made Water quality parameters are submitted to DOH on a monthly basis. Some parameters are measured at the water quality lab inside the WTP, and some are measured at outside July 2017 1 6-19 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan certified labs. Samples are collected from dedicated sample taps at the WTP, the four wells, and additional locations in the distribution system. Various other process related parameters are included in the monthly reports submitted to DOH in addition to water quality data Such information is collected daily and includes • Plant production volume (gallons), • Production time (hours); • Washwater usage (gallons); and • Usage of Aluminum Chlorohydrate (ACH), alum, sodium hypochlorite, coagulant aid polymer, filter aid polymer, caustic soda, and fluoride (pounds). The four wells (Airport, Kiwanis Park, Kissel Park, and Gardner Park) report production volume, production time, and chlorine usage; while Gardner Park also reports fluoride use. State required reports are submitted electronically once a month Two copies are retained at the WTP, each copy resides on separate computer system Data on each of the computer systems is backed up once per month These backups are stored in a separate room from the computers 6.5.1 Surface Water Treatment Rule Monitoring Requirements The SWTR requires special monitoring and reporting requirements for filtered surface waters These requirements are discussed in WAC -246-290-664, -666 and -668 In summary, monitoring and reporting are required for the following 1. Source coliform monitoring. 2 Source turbidity monitoring 3. Filtered water turbidity monitoring. 4 Calculation of inactivation ratio (CT monitoring) 5 Disinfectant residual must be monitored at entry to distribution system and at coliform monitoring sites 6 The following conditions should be reported to DOH before the end of the next business day following the event a Waterborne disease outbreak b Turbidity of effluent exceeds 1 0 NTU c Residual disinfection concentration falls below 0 2 mg/L at entry to distribution system d Emergency events that could affect water quality, such as spills of hazardous materials in watershed or treatment process failures 7 Report all SWTR monitoring results (items 1 through 5 above) within 10 days of the end of each month Monthly reporting requirements are described in detail in WAC 246-290-666(3) 8. Watershed control programs must be developed and updated concurrently with the system's water system plan. Requirements for watershed control are detailed in WAC 246-290-668 Chapter 5 includes a contamination assessment and recommendations for a framework to develop and implement a watershed control program for the City's Naches watershed 6-20 1 July 2017 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan 6.5.2 Violations Procedures Follow-up actions for various types of MCL violations are specified in detail in WAC 246- 290-320. In general, the following actions must be taken each time a primary standard violation occurs: 1 Notify the DOH in accordance with WAC 246-290-480 2. Notify the consumers served by the system. Notification requirements for various types of MCL violations are specified in WAC 246-290-330. 3 Determine the cause of contamination 4. Take any additional actions as directed by DOH. If a secondary standard is exceeded, notify DOH and take action as directed by DOH Follow-up monitoring must be conducted when MCL violations occur. Specific require- ments for follow-up monitoring are described in WAC 246-290-320(2) through (9). Bacteriological violations require repeat sampling in accordance with the City's coliform sampling plan (see Appendix M), and WAC 246-290-320(2) In the case of contamination of the surface supply, the City can shut down the water treatment plant and use groundwater only. The wells are capable of supplying approxi- mately 14 mgd (more than the City's current ADD of 10.5 mgd). The City also has the ability to activate interties with the Nob Hill Water Association. The City's emergency plan (Appendix R) describes procedures for accommodating a WTP shutdown as a result of inadequate finished water quality. 6.5.3 Treatment Optimization Program In 2006, the City of Yakima Council adopted the Washington State Department of Health Treatment Optimization Standards for drinking water. These standards exceed the regular MCL's and regulations for a drinking water filtration plant. In 2012, the Naches River Water Treatment Plant received the Washington State Treatment Optimization Program (TOP) Bronze Award and in 2014 received the TOP Silver Award. 6.5.4 Coliform Monitoring Plan The City of Yakima Water Division has developed a Coliform Monitoring Plan in accordance with the requirements of WAC 246-290-300 and the DOH guidelines presented in Preparation of a Coliform Monitoring Plan. The Coliform Monitoring Plan is presented in Appendix M 6.6 Emergency Response Program The City of Yakima Water/Irrigation Division has developed an Emergency Response Plan for its water treatment plant and distribution facilities The complete plan is shown in Appendix R The system is also a part of the Washington Water/Wastewater Agency Response Network (WAWARN), a network of water and wastewater systems that can provide rapid support to other systems during an emergency 6.6.1 Emergency Call -Up List After normal working hours, emergencies with the water system are handled through an emergency calling procedure. An updated emergency call-up list is maintained in the City's emergency plan. In the event of an emergency, a report is called in to the July 2017 1 6-21 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan Water/Irrigation Division Operations Center, which is staffed 24 hours a day. The Operations Center directs the call to the appropriate person on call. In the event of an emergency situation involving the City's water system, the utility might need to inform the public or other services (such as medical services) immediately Media contact is conducted by emailing bulletins or press releases to the local media representatives on file In addition, the following emergency contact numbers are included for reference • DOH Regional Engineer Andres Cervantes 509-329-2120 • DOH Drinking Water Emergency Number (available 24/7) 1-877-481-4901 • DOH Office of Drinking Water Eastern Region (main line) 509-329-2100 • Ecology Spill Response (Washington Emergency Management Division) 1-800-258- 8990 • EPA National Response Center: 1-800-424-8802 • Local Health Department (Yakima Health District): 509-575-4040 • Yakima Fire Department (non -emergency number): 509-575-6060 6.6.2 Contingency Operational Plan Contingency plans must address the possibilities of loss or reduction of water supply, distribution system disruption, loss of telemetry, and power failure. Sources of Supply Water service from the major water supply source, the WTP, could be interrupted because of high turbidity runoff conditions, extended drought, contamination in the river, or blocking of the intake structure. Should the primary water supply source cease to be available, the following alternatives may be utilized to augment or replace the water system supply needs. • Activation of the City of Yakima's wells. o Failure of the water system's main supply to be available may require rationing or restriction of use of the remaining available water supplies o The City of Yakima's groundwater sources have enough capacity to meet the system's average day demand Restrictions of water use may only be necessary during periods of the year when water usage exceeds the average day demand • Activation of the interties with the Nob Hill Water Association 6-22 1 July 2017 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan o Utilization of the interties with the Nob Hill Water System as a sole source of supply would require rationing. This is because the amount of water available from Nob Hill's water system is limited, especially during the peak use summer months. In addition, the hydraulic capability of the intertie piping and appurtenances is not sufficient to allow flows large enough to meet the City's needs. Ensuring adequate supply to the hospitals on Tieton Drive is of priority; therefore, isolation of parts of the system to direct intertie flows to the hospitals will need to be evaluated to ensure that their supply is adequate • Hauling of potable water from other safe sources o Hauling of water would only be implemented in an extreme emergency when complete loss of the primary, secondary, and intertie sources of supplies has occurred. o Detailed procedures and alternatives for handling a loss of water supply are included in the Emergency Operations Guidelines (Appendix R) In the event of high -turbidity conditions or a spill, the public would be notified to curtail water use for the few days necessary to clean up the spill During drought, an emergency curtailment program would be implemented to limit overall water use to the output of the wells If the 48 -inch transmission main between Gleed and Yakima is compromised, Gleed would be without water because the water treatment plant and 48 -inch transmission main are Gleed's only source of supply and storage. If the WTP is shut down, Gleed does continue to receive water from Yakima through the 48 -inch main from gravity flow from the 1st Level Reservoir. In the event that Gleed is unable to obtain water from the transmission main, WTP staff would contract potable tanker trucks to supply water to Gleed through the Gleed pump station. Distribution system The distribution system in general has adequate redundant piping to continue to provide service in case of disruption of service as the result of a main break or sabotage. In addition, each of the pressure zones can be served from the adjacent pressure zone in case of emergency by using PRVs, booster pump stations, and the emergency interties with Nob Hill Water Association Loss of Telemetry System Another concern is the potential for loss of the radio -based telemetry system due to equipment failure or power interruption. When the telemetry system is not operational, the booster pump stations and wells can be operated manually and would require that the reservoir levels be monitored visually. Power Failure Loss of power has historically not been a serious concern to the water utility because power is nearly always restored within a few hours. The water system has enough reservoir storage to supply demands for the duration of the power outage, and water can be moved from the 3rd Level zone to the rest of the system by gravity. The WTP, Stone Church Pump Station and the 3rd Level Pump Station have standby generators which enables these facilities to remain operation even under extended periods of outage. If a power failure affecting the distribution system is of extended duration, portable generators could be obtained from the Yakima Training Center or Washington State National Guard. July 2017 1 6-23 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan 6.7 Safety Procedures The City of Yakima Water/Irrigation Division practices a safety program to ensure the health and welfare of water system personnel All appropriate Occupational Safety and Health administration (OSHA) and Washington Industrial Safety and Health Administration (WISHA) regulations are followed during operation of the system Maintenance and operation personnel are trained in safety practices, including confined space, asbestos handling, first-aid, fall restraint, and chlorine safety training. Specific safety considerations for the City of Yakima water system are provided in the following sections. 6.7.1 Confined Space Some of the water treatment plant and distribution system valves and other system components are located in vaults or other confined spaces. All water system personnel are trained in confined space safety and the City maintains and operates the required safety equipment (blower, sniffer, tri -pod and harness) necessary to mitigate the dangers associated with confined space. 6.7.2 Asbestos Handling Water/Irrigation Division personnel have been trained on the proper methods for repair and disposal of AC pipe in compliance with OSHA standards. General procedures for handling of AC pipe include: • Notification of the local clean air authority in advance of work if possible. • Use of protective garments. • Wetting of area to be serviced throughout the maintenance work to minimize dust. • Cleaning debris off of tools with wet disposable towels • Placing of towels, scraps, parts, and garments into disposable bag for transportation to nearest landfill. It should be noted that the City of Yakima has only a small amount of asbestos -cement pipe left in the system with the ultimate goal of eventually eliminating all remaining pipe made of this material 6.7.3 Fall Restraint The City's elevated reservoirs (the two 3rd Level Reservoirs) are equipped with safety - climb structures that mitigate the threat of falling to Water/Irrigation Division personnel Appropriate harness -type fall gear is used whenever inspecting reservoir roofs and interiors 6.7.4 Hazardous Chemicals The water treatment plant currently uses on-site generation of sodium hypochlorite for disinfection while the chlorination systems at the wells use calcium hypochlorite tablet systems Operating staff have had training on handling of the disinfection chemicals A hazardous chemical used at the water treatment plant is fluoride in the form of hydrofluosilicic acid. This highly corrosive and toxic chemical is located is a separate building The acid is stored in a high density polyethylene tank with secondary containment for the entire tank volume As in the case of chlorine, the operating staff has 6-24 1 July 2017 Chapter 6 — Operations and Maintenance Program City of Yakima 2017 Water System Plan special training and education to mitigate the potential dangers associated with the handling and use of hydrofluosilicic acid. The Safety Data Sheets (SDS) for these chemical are maintained at the place of use (the WTP and the Water/Irrigation Division Office/Shop facilities) 6.8 Sanitary Survey As part of the Groundwater Rule, all Group A water systems with groundwater sources are required to complete routine sanitary surveys of the system every three to five years The survey evaluates the critical elements of the water system and its operation including • Planning and management documents • Distribution system and status of cross -connection control program • Source and sanitary control area • Source pumps and pumping facilities. • Source treatment procedures and equipment. • Monitoring, reporting, and data verification. • Finished water storage • Operator certification status In the State of Washington, sanitary surveys are administered by DOH. The last sanitary survey for the City was conducted in October 2014 with the letter of finding received from DOH in December, 2014. The survey examined the groundwater and surface water sources, and the storage reservoirs. A copy of the latest sanitary survey and its findings is in Appendix U The only deficiency found by the survey was at the Kissel Park Well where it was improperly sealed during a well repair project. After the deficiency was identified during the field inspection, the City resolved the issue by properly covering the well during the remainder of the well repair project 6.9 Cross -Connection Control Program Section 7 68 070 of the Yakima Municipal Code, titled Cross connection control, requires that, no water service shall be installed or continued in use by the purveyor unless the water supply is protected by backflow prevention devices as may be required by this section. The complete text of Chapter 7.68 of the Municipal Code, including Section 7 68 070, is included in this plan as Appendix E This section of the code, as adopted by Ordinance No 3078, implements WAC 246-290-490 which establishes cross connection control requirements for all community water systems within the State of Washington Section 7.68.070 requires that the policies, procedures, and criteria for determining appropriate levels of protection shall be in accordance with the "Accepted Procedure and Practice in Cross Connection Control Manual --Pacific Northwest Section --American Waterworks Association, Third Edition," or any superseding edition. This manual is incorporated by reference into this water system plan update. A copy of the latest Cross Connection Control Annual Report is included in this plan as Appendix V.

The above procedures manual also includes the necessary forms and checklist that are to be completed for each project. These include the following: • Application for Private Development (Owner/Developer) • Public Improvement Procedure Checklist (Owner/Developer) • Permit to Construct Public Improvements (City) • Consultant Retained for Services Letter (Owner/Developer) • Notice of Substantial Completion (Owner/Developer) • Correction Notice (City) • Affidavit of Release of Liens and Claims (Owner/Developer) • Final Acceptance (City) • Transfer of Ownership (Owner/Developer) 7.4 Design Standards, Performance Standards, and Sizing Criteria The criteria and standards are based, in some cases, on regulatory requirements and, in other cases, on the City's policy for service. The two sources for standards are the Insurance Services Office (ISO) and DOH. 7.4.1 Supply Pump station capacities must be adequate to provide peak -hour demands and fire -flow demands when pumping to a closed system (a pressure zone without storage) For an open system (pressure zone with storage), the capacity of the pump station(s) serving the open system must be adequate to provide the maximum day demand as discussed in Section 3 2 1 All pump stations require a minimum of two pumps for flexible operation The total capacity of the pumps in a given pump station should generally be 25 to 50 percent greater than the calculated required capacity of the pump station, allowing a pump to be repaired without reducing supply capability To increase emergency reliability, at least one pump in each pump station should be equipped with auxiliary power, which would include a diesel generator, a natural gas engine, or an auxiliary hookup so that it can be run from a portable generator to supplement the standard electric motor drive In this way, some emergency supply capacity is available even if a general power outage occurs A similar degree of reliability could be provided if the pressure zone is served by a second pump station, provided the second pump station is on a separate power distribution grid 7.4.2 Storage The design of storage requirements is discussed in Section 3 2 2 July 2017 1 7-3 Chapter 7 — Distribution Facilities Design and Construction Standards City of Yakima 2017 Water System Plan 7.4.3 Distribution The design of distribution requirements (minimum system pressure, minimum pipe size, telemetry, backup power, and valve and hydrant spacing) is discussed in Section 3.2.3. Additional discussion of distribution design standards is provided below: Velocity It is the City's policy that pipeline velocities should be maintained at approximately 3 to 5 feet per second for pumped systems for average demand conditions, 7 5 feet per second for peak -hour conditions, and no more than 9 feet per second for fire flow It can generally be shown that it is more cost-effective (over a facility's service life) to increase the pipeline diameter to maintain 3 to 5 feet per second than to increase the pump horsepower Pressure Zone Boundaries Pressure zone boundaries are based on service elevations and reservoir overflow eleva- tions Zones are isolated though the closing of valves or pressure reducing valves (PRVs) such that the lower boundary of a zone is along the ground surface contour that results in pressures of no more than 100 pounds per square inch (psi) during static conditions (usually occurring in the early morning hours) The upper boundary of the zone is along the ground surface contour that generally results in static pressures of no less than 40 psi This low-pressure standard is usually sufficient to ensure that the pressure will not be below 30 psi during peak demand conditions Only the minimum number of pressure zones should be created. Wherever pressure zones are created, the system becomes fragmented and the water conveyance capacity can be severely limited by the PRV "bottleneck " Also, it is desirable to limit the number of PRVs because as a mechanical device they require maintenance and are subject to failure ISO fire -fighting standards consider pipelines much more reliable than PRVs The number of PRVs serving any given zone should be sufficient to meet fire -fighting requirements if one is out of service. Therefore, at least two, and ideally three, PRVs should serve each zone Waterline Separation The City has developed separation requirements between waterlines and non -potable pipelines. These requirements are included in Appendix Y. 7.5 Construction Standards, Materials, and Methods Specifications for the materials and methods of construction of water system extensions are included in the most current edition of the Washington State Department of Transportation Standard Specifications for Road, Bridge, and Municipal Construction as modified by the Specifications for Private Construction of Public Water Mains for City of Yakima Refer to Appendix X for complete information regarding specifications The City maintains a number of standard details related to the construction of water distribution system pipes and appurtenances These details can be found in Appendix Z The City also maintains a listed of general construction notes for public waterline construction which can be found in Appendix AA. 7-4 1 July 2017 Chapter 7 — Distribution Facilities Design and Construction Standards City of Yakima 2017 Water System Plan 7.6 Construction Certification and Follow-up Procedures The steps that the City's Engineering Division takes to assure that a water system extension project has been constructed in accordance with the applicable standards are described in the above referenced procedures manual found in Appendix W July 2017 1 7-5 Chapter 7 — Distribution Facilities Design and Construction Standards City of Yakima 2017 Water System Plan 7-6 1 July 2017 This page left intentionally blank 8 Capital Improvement Program This chapter provides a summary of the City of Yakima's water system Capital Improvement Program (CIP), and presents the costs and schedules for projects planned for implementation in 2017 to 2037. 8.1 Development of CIP The CIP was prepared by first identifying projects that address water system needs or deficiencies, as documented in earlier chapters of the water system plan In addition, recurring or annual capital projects related to system maintenance (e g , water main replacement programs) have also been included in the list of improvements A 20 -year implementation schedule of the projects was then developed Generally, projects of higher priority were scheduled for implementation within the 10 -year planning horizon (2017-2026) Projects that serve anticipated future needs associated with system growth, or are less critical to system operation, were scheduled for implementation at a time from 2027 to 2037 Detailed scheduling of the higher priority projects was based upon the City's existing implementation timelines for projects that had been identified prior to initiation of this WSP, together with a prioritization process where the City evaluated each project against a set of prioritization criteria 8.2 Capital Project Costs Planning -level cost estimates have been developed for the capital projects and programs included in the 20 -year CIP Generally, each project cost includes the following components • Base construction cost: Includes all labor and material costs needed to construct a project For distribution system projects, construction costs were estimated using preliminary quantities and unit costs based on the project's planned alignment and scope of work. Unit costs were based on published values from a cost database of average national unit costs, then escalated to 2016 dollars with a location factor applied to adjust for the difference in costs for Yakima compared to the national average13 • Construction contingency Takes into account the uncertainties associated with estimating project costs at the planning level. Calculated as 30% of the total of base construction cost. • Sales tax Calculated as 8 2 percent (the 2016 local tax rate) of the base construction cost. • Contractor overhead and profit Takes into account the contractor's overhead and profit applied to base construction costs This ranged from 25 percent to 30 percent of the base construction cost depending on the size of the project Projects that are planned to be completed by City staff and resources (instead of an outside contractor) do not include overhead and profit 13 The RSMeans Heavy Construction Cost Data (2014) cost database is used. Prices adjusted to Yakima using a factor of 99 (national average = 100). 2014 cost data escalated to 2016 dollars using the Engineering News Record (ENR) construction cost index (CCI). July 2017 1 8-1 Chapter 8 — Capital Improvement Program City of Yakima 2017 Water System Plan • Indirect construction costs: Includes City and consultant design costs, and other related cost items, such as permitting and construction administration Depending on the size and scope of the project, this ranged from 20 percent to 25 percent of the total of the base construction, construction contingency, sales tax, and contractor overhead and profit. In addition to the percentage, projects requiring temporary and/or permanent easements included an easement acquisition cost based on the area of easement required. These above elements are totaled to determine the total planning -level cost estimate for a project, as expressed in 2016 dollars The above methodology applies to costs developed for improvements first identified through the work completed as part of this water system plan update. Projects identified in past planning efforts which had a cost previously developed had the cost escalated to 2016 dollars using the construction cost index (CCI) published by Engineering News Record (ENR). 8.3 Capital Project Prioritization 8.3.1 Prioritization Criteria and Methodology The improvements identified in this Water System Plan Update are categorized into the following functional component categories • Water Quality (WQ) • Water Treatment Plant (WT) • Source (S) • Distribution (D) • Water Planning (WP) Descriptions of the projects are included in Chapter 3, System Analysis Figure 8-1 provides the locations for the major planned improvements. The identified improvement projects have been evaluated and prioritized based on the following criteria to determine the time in the 20 -year CIP a project would be implemented • Regulatory Requirement or Binding Commitments Does the improvement address a deficiency in meeting mandatory requirements/commitments (fire flow requirements; level of service requirements; Department of Health design criteria, regulations, and standards)? Typically for fire flow improvements, projects addressing a fire flow deficiency that is within 15 percent of the fire flow goal are regarded as having a lower priority. 8-2 1 July 2017 f •dr -- f111C�k Lit IV f 111101 116 • • 'M. ilinliWimmilla mni - \" • mu4 MiliL =1' ice- A. •s it " MI ogM:.10 r��1tn -..D, IIlMI■ MIN■m■r■■■'■!im■■mo■■■■■ imoitrio$00 iv* EMMEN S-2 Stone Church Pump Station Improvements D-1 North 41st Avenue and North 42nd Avenue Waterline Fire Flow Improvements D-2 Peach Street Waterline Fire Flow Improvements D-3 South 1st Avenue Waterline Fire Flow Improvements D-4 North 3rd Street Hydrant Improvement D-5 Bartlett Place and Gordon Road Waterline Fire Flow Improvements D-6 Chesterly Lane Hydrant Improvement D-7 North 3rd Avenue Waterline Fire Flow Improvements D-8 North 31st Avenue Hydrant Improvement D-9 South 2nd Avenue and Division Street Waterline Fire Flow Improvements D-10 Perry Street Waterline Fire Flow Improvements D-11 South 4th Avenue Waterline Fire Flow Improvements D-12 South 6th Street and East Chestnut Avenue Hydrant Improvement D-13 East Mead Avenue Water Main Fire Flow Improvements D-14 Fruitvale Boulevard Waterline Improvements D-16 East Viola Avenue Waterline Improvements D-17 Viola Avenue Freeway Crossing Improvements D-18 Longfibre to South 1st Street Water Main D-19 North 1st Street Waterline Improvements - Phase 1 D-20 North 1st Street Waterline Improvements - Phase 2 D-21 North 1st Street Waterline Improvements - Phase 3 D-22 North Front Street Waterline Improvements D-23 West I Street Waterline Improvements D-25 Englewood Avenue AC Waterline Replacement D-26 Hathaway Street Waterline Improvements D-28 Del Monte Site Waterline Replacement D-32 Mill Site Redevelopment 11E1 * D-9 `�l't :: `•'iiia.

Does the improvement reduce operation and maintenance needs, and improve the reliability of the system? Could costs be reduced through project subsidies (partially or completely) by others (such as grants or developer funds)? • Future Growth Does the project support future growth and development within the system? • Costs and ease of implementation How easy will it be for the improvement to be accepted, designed, constructed, and financed? What are the capital costs for the project and are they justified given the benefits provided by the improvement? City Water/Irrigation staff met with the contracted water system planning engineer in a workshop to apply the prioritization criteria to each project and determine project scheduling. The group decided that given the limited number and types of projects identified, a formal scoring matrix was not necessary and that projects would be qualitatively compared to each other while considering the prioritization criteria listed above. In general, the highest priority projects are scheduled for the first several years of the CIP A portion of the projects were identified by prior planning efforts which already established a project timeline In those cases, the previous timelines were maintained The remainder of the projects that were determined to take place in the 10 -year plan were distributed across the 10 -year plan to level out capital costs for each year. 8.3.2 Project Prioritization Descriptions The following provides a brief summary of how the above prioritization criteria apply to each identified project in the CIP WQ-1 TOC Monitoring and/or TTHM Treatment Regulatory Requirement or Binding Commitments To be determined (TBD) Water Quality (non -regulatory) TBD Reliability, cost control, and O&M: TBD Future Growth TBD Costs and ease of implementation: TBD Summary As a condition of its ASR permit, the City will complete an engineering technical memorandum that will describe and evaluate a range of treatment and monitoring options TOC monitoring and/or TTHM treatment will be developed following the completion of the engineering technical memorandum 8-4 1 July 2017 Chapter 8 — Capital Improvement Program City of Yakima 2017 Water System Plan WT -1 Rechanneling River Intake Regulatory Requirement or Binding Commitments N/A Water Quality (non -regulatory): N/A Reliability, cost control, and O&M Project is necessary for the WTP intake off the Naches River to function properly Without the project, temporary solutions would have to continue to be implemented at an added cost and with the risk of the intake limiting the WTP's capacity Future Growth: The project will allow the WTP to maintain its capacity based on its treatment system capabilities (filters) and not be limited by the intake capacity. The WTP operating at its full rated capacity will allow future growth and development. Costs and ease of implementation Project will require in -river work adding to the complexity of construction Project has a high cost compared to other planned projects Summary Project is of a higher priority to maintain the capacity of the WTP intake Project will be scheduled to occur early in the 10 -year CIP WT -2 Residual Handling Improvements Regulatory Requirement or Binding Commitments: N/A Water Quality (non -regulatory) N/A Reliability, cost control, and O&M: Project may be necessary for the WTP to maintain operations at full capacity. Future Growth The project will allow the WTP to maintain its capacity based on its treatment system capabilities (filters and backwash recycle lagoons) and not be limited by the residual handling capacity during higher solids production years The WTP operating at its full rated capacity will allow future growth and development. Costs and ease of implementation TBD Summary: Project cost and schedule will remain TBD pending further study. S-1 Additional Source Wells (ASR) Regulatory Requirement or Binding Commitments: N/A Water Quality (non -regulatory) N/A Reliability, cost control, and O&M: Project would allow for improved reliability of the water system. If the WTP has to be taken out of service or have its production greatly reduced during peak season demand, the City would be unable to meet demand given the current collection of seasonal wells. The addition of the ASR wells would allow complete redundancy for source capacity if the WTP is taken offline. The project would also allow improved flexibility in the system to handle peak demands The ASR wells would also provide a regional reliability benefit for water supply from the region's aquifer Future Growth: The project will significantly increase the source capacity of the system allowing for future growth beyond the 20 -year planning period. Costs and ease of implementation Project has the highest cost out of the projects listed in the CIP Project would require significant planning and design prior to construction Summary: To improve the reliability of the water system and to have adequate source capacity if the WTP is taken out of service, this project is considered to have a higher priority. Project will be scheduled to have one well completed early in the 10 -year CIP and the other well completed later in the 10 -year CIP.

A comprehensive financial program provides a detailed account of the way to fund the capital plan and show the utility is funded in a financially sustainable manner over the course of the planning period The state of Washington requires a financial program contain details which demonstrate that the financial program is viable WAC 246-290-100 states a water system plan must contain within their comprehensive plan a description of the Utilities financial program The code specifically calls for "(j) Demonstration of financial viability by providing: (1) A summary of past income and expenses (ii) A one-year balanced operational budget for systems serving 1,000 or more connections or a six year balanced operational budget for systems serving less than on thousand connections (iii) A plan for collecting the revenue necessary to maintain cash flow stability and to fund the capital improvement program and emergency improvements; and (iv) An evaluation that has considered: (A) The affordability of water rates; and (B) The feasibility of adopting and implementing a rate structure that encourages water demand efficiency." In this chapter, the Washington Administrative Code (WAC) required components, listed above are provided plus some additional information integral to the management of the City's water system. The financial program for this Water System Plan update includes the following information • Past and present financial status • Sources and uses of funds • Capital funding plan and project financial results • An assessment of rates The methods used in this study followed general industry guidelines for developing utility rates — rates must generate enough revenue to be self-supporting and financially viable, without undue discrimination toward or against any customer July 2017 1 9-1 Chapter 9 — Financial Program City of Yakima 2017 Water System Plan 9.2 Past and Present Financial Status The City operates their domestic water utility as a self-supporting entity and provides affordable domestic water to its customers The City conducts regular rate studies, providing independent assessment of the financial health of City utilities Management strives to keep the price of water as low as possible, providing high quality water to its customers while still maintained an adequate reserve balance.

Proposed rate adjustments were five years of 4.0 percent increases (2014-2018). The study also proposed a shift in the City's rates, weighting more heavily on the fixed change and less on the consumption rate. The overall change to the rate was from 22 to 27 percent weighted on the fixed charge. 9.2.2 Financial Policies The City maintains several financial policies in the areas of reserve levels and debt management. Financial policies are important for a few reasons. Financial polices help guide the utilities management into the future in a prudent and sustainable manner. Bond rating agencies consider strong financial policies as favorable when assessing the utilities bond rating. The following financial policies were incorporated into the analyses: • Self -Sufficient Enterprise Fund — The Governmental Accounting Standards board (GASB) defines an "enterprise fund" as a fund that operates a business like activity and is primarily funded by user fees such as water rates Because the water utility is designated as an enterprise fund, it must be self-sustaining and recover its operating and capital costs Enterprise funds cannot be subsidize or subsidize another fund including the City's general fund • Reserve Levels — Reserve balances are necessary to cover current costs as well as future capital expenditures Adequate cash reserves help the utility run smoothly and maintain stable rates in the future. o Operating Reserves provide day to day funding of operations and the balance must be sufficient to cover the utility's bills, payroll and unexpected costs particularly taking into account the seasonal nature of water utility revenue. The most recent rate study recommends between 45 and 60 days of O&M expense or between 12 and 16 5 percent annual O&M expense. o Capital Reserve hold funds intended to fund the City's capital plan. The most recent rate study suggests a minimum balance of 1 to 2 percent of fixed assets Historically the City has maintained a minimum balance of $750,000 which is within the recommended 1 to 2 percent minimum balance The Capital Reserve may also hold some restricted revenue in the form of impact fees also known as system development fees o Restricted Debt Reserves are reserve funds held with a required balance equal to the City's principal and interest payments These funds are held to safeguard bond holders in the event the City's current revenue is not sufficient to make bond payments Generally, these funds are held until the bonds mature and are then used to pay the final bond payment. The City has historically issued bonds to help fund capital improvement projects and this practice is assumed to continue into the future • System Reinvestment Funding — The purpose of system replacement funding is to provide for the replacement of aging system facilities to ensure sustainability of the system for ongoing operations The prior rate study incorporates direct rate funding for 9-4 1 July 2017 Chapter 9 — Financial Program City of Yakima 2017 Water System Plan capital projects in the amount of $600,000 to $650,000 per year. This level of funding approximates annual depreciation expense less debt principal payment; no additional funding was deemed necessary for system replacement at that time. It should be noted that this method will not fully recover costs equal to asset replacement over time. Simple straight line depreciation will only recover the cost of the asset at the time it was installed or constructed. Water system assets are routinely depreciated over 20 years or more, and assuming construction cost increases of 2 5 percent, the cost to replace a system asset will be 64 percent higher after it is fully depreciated • Debt Service Coverage Ratio (DSCR) - The City's current minimum coverage requirement on outstanding revenue bonds is 1 25 times annual revenue bond debt service, using the net revenues of the Utility The City's has an internal policy to set rates so that the utility will meet coverage of at least 2 0 times annual revenue bond debt service • Debt Management — The City's general policy is to maintain debt service below 25 percent of the total utility budget. Debt service is currently 9 percent of the budget, increasing to 15 percent of the budget by the end of the study period. 9.3 Sources and Uses of Funds 9.3.1 Sources of Funds Revenue for the water system operations are derived from rate revenue for metered water sales, miscellaneous revenues such as connection charges and penalties, other water sales, new service fees, connection charges, and miscellaneous revenue. The chart below shows that the vast majority of the operating fund's revenue is received through rate revenue collections. Figure 9-1. Revenue Sources Other Water Sales 0.2% New Service Fees 0.9% Connection Charges Misc. Revenue 1.7% The capital plan has been funded by a combination of available sources, low interest loans, grants, cash transfers from the Domestic Water Utility Operating Fund, and interest income. A Public Works Trust Fund (PWTF) loan was obtained in September of 2003 in the amount of $2,694,500. These loan funds were used for the WTP improvement project which included rapid mix (pumped flash mix) improvements, on-site chlorine for disinfection, new chemical feed and storage equipment, and pipe gallery modifications. A DWSRF loan of $957,200 July 2017 1 9-5 Chapter 9 — Financial Program City of Yakima 2017 Water System Plan was obtained in 2004; these funds were used for filter improvement at the WTP. A PWTF loans for $2,257,200 was obtain in 2008 for the Gardner Park Well. The PWTF and State Revolving Fund (SRF) loan programs have been on the decline in the last few years due to state budget constraints The analysis assumed utilization of revenue bonds and increased funding through rates fund capital projects City staff will continue to seek low interest alternatives and grants as they are available Interest income is generated from the investment of available annual balances in the water utility capital fund An average annual interest rate of 4 0 percent was assumed in the 2007 Rate Study Currently most interest rates are less than 1 percent 9.3.2 Application of Funds A water utility incurs a variety of expenditures including O&M, capital funding, debt service and taxes. Figure 9-2. Revenue Requirement Supplies and Equipment 6% Interfund 16% Salary and Benefits 30% Debt Service 11% Utilities 4% Misc. Expenses 6% Taxes & Transfers 27% Operations and Maintenance O&M expenses are comprised of a variety of costs associated with the day to day operations of the utility Salaries, benefits, supplies, interfund payments, and utilities are a few of the largest O&M expenses Growth rates for these objects vary widely Total salaries, the largest component of O&M, generally can only be reduced by reducing staff as individual salaries generally rise with an index such as the consumer price index or something similar often negotiated with union contract terms Benefits comprise a wide range of items such as health insurance and pension. Historically health benefits have been growing at a rate significantly higher than inflation. Taxes The utility pays two types of taxes, a state tax of 5 029 percent which is charged to all water sales and a Payment in Lieu of Tax (PILOT) which is a payment to the City's general fund The PILOT is calculated as 20 percent of total revenue less debt service Since the state tax 9-6 1 July 2017 Chapter 9 — Financial Program City of Yakima 2017 Water System Plan and City PILOT are calculated as a percent of revenue, when rates are increased, additional State taxes and City PILOT are incurred equal to a quarter of the overall rate increase. Capital Funding Utilities fund capital in many ways, through rate revenues, impact fees, reserves or long-term debt in the form of loans or bonds Often utilities employ several means of funding capital projects and for a variety of reasons. At times capital funding mechanisms are restricted to certain uses such as funding capacity related projects or possibly loans secured for particular projects. Bonds can also be restricted to what the utility stated they were going to fund with the bonds at the time the bond was issued. Capital Funded Through Rate Revenue - Some utilities choose to fund their capital plan entirely through current revenue and reserve funds, however is rare because utilities are often discouraged from holding excess cash balances Most utilities use a mix of capital funding mechanisms such as debt As it happens the amount of capital a utility funds through rates is indicative of the financial health of the utility Debt Service - is the payment of principal and interest on debt issued by the utility Often when a utility issues debt the issuer imposes covenants on the utility to assure the utility is sufficiently financially sound to be able to repay the debt. One common covenant imposed is a DSCR which is commonly stipulated at 1 25 for revenue bonds This means after expenditures and taxes are paid, the Utility has revenue equal to 125 percent of the debt service remaining (see equation) The city currently has one outstanding bond issue set to be paid off in 2021 that accounts for approximately 4 percent of the City's total debit The City's largest portion of debt service is from PWTF and SRF loans which usually have 1 0 DSCR requirement This financial statistic assures the utility is not spending all of its revenue on operations Revenue — Expendtitures — Taxes Debt Servtice => 1.25 The level of debt the city carries is critical for a utility as the proportion of debt to revenue, called debt service coverage ratio is one financial statistic that determines the City's capacity to borrow additional funds as well as the overall bond rating. The City's target for DSCR is 2 0 which is a well above the typical minimum required by bond covenants and twice the PWTF and SRF loan requirements 9.4 Capital Funding Plan and Projected Financial Results As mentioned earlier, a major component of a capital plan is how it will be funded. To adequately determine how a capital plan will be funded a financial plan must be undertaken. A financial plan, while not necessarily as comprehensive as a full rate study, has similar objectives and methods. While there are a few generally accepted methods for conducting a financial plan the City has historically used the cash basis for determining the revenue requirement. This analysis has also used the cash basis to be consistent with past analyses. The cash basis revenue requirement analysis is the comparison of projected revenue and revenue requirement to determine if the revenue is sufficed to responsibly manage the utility. The components of a cash basis revenue requirement are available funds or revenue, compared to the application of funds (see equation). Table 9-2 summarizes the components that make up the application of funds. Balance (De fluency) of Funds = (Avatilable Funds) — (Applticattion of Funds) July 2017 1 9-7 Operations & Maintenance Capital Funded Through Rates 1 Taxes and Transfers Debt Service Chapter 9 — Financial Program City of Yakima 2017 Water System Plan Table 9-2. Overview of a Cash Basis Application of Funds Application of Funds Capital funded through rates and debt service is the two areas where the capital funding plan affects the revenue requirement In the capital funding plan the assumed bond issues will Increase the debt service in addition to an increased level of capital funding through rates The central purpose of this analysis is to develop a funding strategy for the capital plan developed for this Water System Plan. To that end, the capital plan used for this analysis is a real dollar representation of the capital plan developed in the earlier section of this document.

Beyond 2017 escalation factors were used for the projections. Escalation factors were ranged from 6 to 0 percent depending on the particular expense or revenue. Table 9-5 provides the escalation factors used in the financial plan. Table 9-5.

The results of the analysis showed the need for 8.5 percent rate increases in both 2017 and 2018, then 5 percent annual increases in 2019 through 2023, and then settling on 3 percent per year thereafter. The impact to the City's average single family customers peaks at $2.40 per two month billing period to in 2018 but otherwise averages $1.68 per bill among all the analysis period July 2017 1 9-11 Chapter 9 - Financial Program City of Yakima 2017 Water System Plan Table 9-6.

The table shows that DSCR fluctuates from year to year depending on the level of outstanding debt and the revenue including assumed rate adjustment in any year. The City's policy is that DSCR should target 2.0, meaning the funds remaining after subtracting O&M, taxes and transfers should be twice the annual debt service payment. Rating agencies consider a 2.0 as a very strong DSCR. The results show that the City is within range of their target in most years and averages 1 9 over the analysis period The City's maximum debt service as a percentage of revenue requirement is well below the policy of 25 percent throughout the analysis period The Operating Fund balance target is 60 days of O&M The analysis indicates that the City is estimated be at a minimum of 68 days and as high as 123 days of O&M expense The Capital Reserve Fund balance fluctuates year to year depending on the timing of bond issues On average, during the analysis period the ending fund balance greatly exceeds the $750,000 target and on an annual basis the ending fund balance in not expected to drop below the City's ending fund balance target 9.5 Assessment of Rates Given the rate adjustment proposed in this section, the City should be able to adequately fund the capital program and run its operations in a sustainable manner The City bills its customer on a bimonthly basis. The existing water rate structure consists of a ready to serve charge based on meter size and a volumetric rate per hundred cubic feet (CCF) of consumption. Table 9-8 provides a historical perspective of the City's rates from 2009 to 2015. Previous to 2009, the City's rates were declining rate which is not considered conservation oriented rates. Declining rates is based on the premise of a volume discount which has been found to be contrary to conservation efforts. Table 9-8.

The City has been slowly shifting their rates to a structure that encourages conservation. Table 9-9 and Table 9-10 provide projected future rates given its current rate structure and the proposed rate increases. It should be noted that this is a somewhat simplified projection given the available data at the time of this study, and the rate study that is schedules to take place in 2017 may have results that very from this table due to updated data. All charges for water supplied outside the city, including fire service shall be computed by multiplying the applicable rates set forth in Table 9-9 and Table 9-10 of this section by one and one-half (1 50) May 2016 1 9-15 Chapter 9 — Financial Program City of Yakima 2017 Water System Plan Table 9-9.

Though it has not been deemed an industry standard, the EPA stated in a 1997 paper titled EPA published Guidance for Financial Capability Assessment and Schedule Development, that an unaffordable rate would be an annual bill in excess of 2 percent of Median Household Income. The Census Bureau's American Community Survey estimates the City of Yakima's Median Household Income to be $40,726 per year in 2015 An average single family household's annual water bill is estimated to be $158 per year Dividing the average annual bill by the Median Household Income produces values from 0.3 to 0.4 percent in 2009 and through 2015 as shown in Table 9-11. Table 9-11. Median Household Income Compared to Average Single Family Rates 2009 2010 2011 2012 2013 2014 Median Household Income $37,351 $39,706 $41,071 $40,569 $39,462 $40,189 $40,726 Estimated Annual Single Family Water Bill Water Costs as % of MHI MIN -M71111 0 3% 0 3% 0 3% 0 4% 0 4% 0 4% 0 4% If one were to consider 2 percent of Median Household Income a threshold of affordability it would be very clear that the City's rates are very affordable. For the City's rates to rise to the level to be unaffordability using this measure, the rates would have to increase by five times its current level assuming no growth in Median Household Income. The cumulative effect of the rate increases for this analysis is 64 percent, which means that the City's rates will likely remain affordable during the analysis period of this plan July 2017 1 9-18 Appendices This page left intentionally blank Appendix Table of Contents A SEPA Determination of Non-Significance B.

Date checklist prepared: May 3, 2017. 5. Agency requesting checklist: As the agency initiating this proposal, the City of Yakima is the lead agency and is requesting the checklist. 6. Proposed timing or schedule (Including phasing, if applicable): The 2017 City of Yakima Water System Plan Update (Plan) evaluates the existing water system and projects future domestic, irrigation, and water supply needs in phases through the year 2042. Please refer to the schedule in Chapter 8 of the Plan for a description of the proposed capital improvement plan (CIP) The Plan proposes phased implementation of a variety of physical projects and administrative programs that would address future demands for the supply, transmission, and operation of a potable water system within Yakima's water service area. The Plan recommends implementing modifications to supply, distribution, and storage facilities in the service area to ensure that projected and potential demands can be met. New water supply operations programs are City of Yakima EVALUATION FOR AGENCY USE ONLY ECEIVED MAY 1 ' 2017 CITY OF YAKIMA PLAltiN N DIV- May 3, 2017 2 Environmental Checklist also recommended. The Plan recommends increasing the supply capacity by installing new Aquifer Storage and Recovery (ASR) wells, constructing improvements to the WTP, constructing additional distribution lines within the City of Yakima, maintenance of existing pressure reducing valves, and implementing annual operations programs for water conservation, leak detection, and corrosion control. The physical projects mentioned above are elements of the City's recommended water system Capital Improvement Program (CIP). The proposed construction dates for the City's water system CIP projects are listed in Chapter 8 of the Plan. The Plan recommendations would be implemented in two phases: Phase I, a 10 -year phase from 2017 to 2027, and Phase II, the remaining 10 years of the 20 -year timeframe covered by this Plan. Population and water demand projections in this Plan were made for a 20 -year planning horizon. Recommendations for the Phase II years of the 20 -year planning horizon will be reviewed and modified as part of subsequent Plan updates. The CIP projects listed in Chapter 8 of the Plan are subject to change, depending upon the rate, location, and nature of future development within the City and its service area and should not be construed as a commitment by the City to complete a project by a specific date. Actual project implementation will be based on subsequent environmental review, permits and approvals, available funding sources, and scheduling requirements. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. This Water System Plan Update is in itself such a plan. The Plan is required to be updated every 10 years. Those CIP projects planned for implementation after the year 2027 will be part of the next Plan Update and specific impacts associated with these projects are not covered by this checklist. The appropriate level of environmental review consistent with SEPA requirements will be conducted for those projects in the future. 8. List any environmental information (studies, reports, etc.) you know about that has been prepared, or will be prepared, directly related to this proposal.

(You may attach a page if this space is not adequate.) City of Yakima. The Water System Plan Update analyzes the existing City of Yakima domestic water system including water supply, storage, distribution, and operations. The study has projected future water demands based on potential domestic needs. Modifications to the existing domestic system are recommended to ensure that projected water demands can be met. Future decisions and political or legal actions (such as in regard to the City's water rights or irrigation conversion) could result in the need for a subsequent plan update or amendments to this plan. The recommended water system improvements presented in this Plan relate to four aspects of the system: the supply program, storage and pump station facilities, distribution system, and system operations and management. Recommended improvements to the supply program include modification to the Naches River WTP required to improve operational efficiency and RECEIVED MAY 1 ' 2017 CITY Of YAKIM 4 PLA": ';.:,;,l DIV. May 3, 2017 4 Environmental Checklist EVALUATION FOR AGENCY USE ONLY installation of new wells (two future ASR wells) needed to meet anticipated future demands and to meet reduced water supply due to climate change. Recommended improvements to the domestic water distribution system include: The following distribution projects, while not needed to correct any existing deficiencies, are included in the capital improvement program as part of the City's on-going efforts to maintain and upgrade the quality of the system to meet current and future needs. Advanced Metering Infrastructure (AMI) Battery Replacement/ System Upgrade. Project is currently not necessary. However, as the AMI ages the program will need to begin being implemented. Program will be placed in the long-term CIP with costs to be determined. City of Yakima. Private Water Main Replacement Program: This on-going program replaces private mains less than 6 -inch (in some cases 1 -inch galvanized) and complete loops in the areas where these mains are replaced. This project improves domestic flows to current residential customers, provides fire protection in areas where no fire hydrants have previously existed and improves overall system performance and reliability by looping the new mains to existing mains. Open Gear Valve Replacement: Project will be placed as an annually recurring program throughout the 20 -year CIP to address valve replacements as they become necessary. Lead -Oakum faint Waterline Replacement Program: Due to the significant maintenance issues surrounding the continued use of these pipes, these projects will be given a higher priority with identified projects scheduled for completion within the 10 -year CIP. An annually recurring cost will also be included throughout the 20 -year CIP to address not yet identified lead -oakum joint waterline replacements. Distribution Main Leak Detection: Due to the relative ease to complete the program and the benefits for lowering distribution system losses, the leak detection program will be scheduled early in the 10 -year CIP. Recommendations to improve system operations programs include continuation of a corrosion control program, leak detection program, wellhead and watershed protection programs, groundwater monitoring program, and water conservation program.

May 3, 2017 5 Environmental Checklist 12. Location of the proposal: The Water System Plan would be implemented throughout Yakima's water service area. The service area boundary is shown in Figure 1-5 in the Plan. Recommended improvements are in Table 8-1 of the Plan. At this time, the exact locations of the proposed ASR wells, are not known. It is anticipated that these new facilities will be located at or near existing utility sites or on available vacant land within the City's jurisdiction. B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site (underline one): Flat, rolling hills, steep slopes, mountainous, other varies . b. What is the steepest slope on the site (approximate percent slope)? Does not apply c. What general types of soils are found on the site (for example; clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The soils types vary throughout the approximately 19 -square -mile service area. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Does not apply e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Some grading and filling would occur during pipeline replacement and other construction projects. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Because the proposed distribution mains would be located beneath relatively flat, already developed areas (e.g., paved roads), erosion from construction activities for these activities is expected to be low. Similarly, erosion is anticipated to be low at the WTP site as a result of improvements to be constructed within the existing facilities. Construction of the groundwater wells, could result in increased erosion, depending on the specific City of Yakima.

No erosion impacts are expected from use of the water system improvements. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The projects identified in the plan are not expected to result in any increase in the amount of impervious surfaces associated with the water system facilities. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: If required, erosion control measures at new construction sites would be based on applicable local and regional ordinances and/ or guidance manuals. General erosion and sediment control measures that could be implemented during site grading include spraying water or other dust control agents on graded areas to control dust, placing erosion control fences and/or straw bales at the toes of freshly graded slopes to reduce surface water velocity and offsite siltation, and revegetation of graded areas as soon as feasible after grading is complete. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities, if known. Construction of the recommended facility improvements would slightly increase air emissions (i.e., dust and equipment exhaust) during construction by vehicle and wind erosion over exposed earth surfaces. Clearing and grading activities comprise a major source of these temporary construction emissions. The severity of construction emissions is extremely variable, and depends on wind speed, soil type, soil moisture, the type of construction activity, and acreage affected by construction activity. b. Are there any off-site sources of emissions or odors that may affect your proposal? If so, generally describe. Does not apply c. Proposed measures to reduce or control emissions or other impacts to air, if any: Construction dust can be controlled by watering disturbed areas. Active construction areas will be watered whenever soil moisture conditions and weather conditions result in visible dust generation. Dust -producing activities will be suspended during period of high winds if dust control measures are unable to avoid visible dust plumes. All finished grades will be immediately treated with an appropriate soil binder. City of Yakima. EVALUATION FOR AGENCY USE ONLY RECEIVED MAY 1 = 2017 CITY OF YAKIMA PLA"';N:: 3 DIV. May 3, 2017 7 Environmental Checklist 3. WATER a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The WTP diverts water from the Naches River, a tributary to the Yakima River. The domestic water service area is bound on the East by the Yakima River and on the North by the Naches River. Several creeks and lakes lie within the area. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No work is anticipated within 200 feet of either the Naches or Yakima Rivers. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. It is anticipated that new facilities would be sited to avoid direct impacts to surface water and wetlands. Potential impacts to surface water or wetlands associated with future facilities will be addressed under subsequent SEPA environmental review. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. The City currently diverts about 23 MGD at the treatment plant to meet peak demands. Additional groundwater rights through ASR would likely be needed by 2020. 5) Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. Portions of the service area are within the 100 -year floodplain. The only known projects planned within a floodplain are the WTP improvements. Environmentally acceptable construction methods and protection features will be incorporated during planning and design of these facilities, most of which will be installed within existing structures or buildings. In addition, an existing dike separates WTP facilities from the Naches River, therefore, no significant impacts are anticipated from construction within this floodplain area. Any potential impacts associated with construction of other facilities within a floodplain will be addressed under separate SEPA reviews. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No wastes would be discharged into the ground as a result of the proposed project. b. Ground: City of Yakima. EVALUATION FOR AGENCY USE ONLY RECEIVED MAY 2017 CITY OF YAKIMA PLAN :C2 DIV May 3, 2017 8 Environmental Checklist EVALUATION FOR AGENCY USE ONLY 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. Historically, the City of Yakima has used groundwater only as an seasonal/emergency source of supply. The capacity of its existing emergency ground water sources totals 13 MGD. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals; agricultural; etc.). Describe the general size of the system, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material would be discharged into ground or surface waters as a result of the proposed project. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will the water flow into other waters? If so, describe. No increase in the amount of impervious surfaces or run-off are anticipated as a result of the improvements identified in the plan. 2) Could waste materials enter ground or surface waters? If so, generally describe. No waste material would be discharged into ground or surface waters as a result of the proposed project. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: In addition to implementing a water conservation program, replacing obsolete and deteriorated water mains will also help to conserve water. Developing a leak detection program will also help protect impacts to groundwater supplies. 4. PLANTS a. Check or underline types of vegetation found on the site: x deciduous tree: alder, maple, aspen, other (oak) x evergreen tree: fir, cedar, pine, other x shrubs x grass x pasture x crop or grain x wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other RECE1 V D City of Yakima.

What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The tallest height of any new structures will be the well houses for the new wells. They will have a height of 12 to 14 feet and will also include a small antenna for the telemetry system. The exact height of the antenna has yet to be determined but would probably be 30 feet or less. b. What views in the immediate vicinity would be altered or obstructed? Proposed distribution mains and the groundwater well are subsurface facilities and would therefore not alter or obstruct any views. The new well houses would also likely be located in already developed, urbanized settings; therefore, it is not anticipated that these projects would alter or obstruct any scenic views. Future site-specific SEPA review for these proposed new facilities will address potential aesthetic impacts in more detail. c. Proposed measures to reduce or control aesthetic impacts, if any: The planning and design of projects recommended in the Plan would carefully consider aesthetic values. It is anticipated that new above -grade facilities (i.e., well houses) would likely be located in already developed, urbanized settings and therefore would not have a significant adverse aesthetic effect on local visual resources. 11 LIGHT AND GLARE a. What types of light or glare will the proposal produce? What time of day would it mainly occur? Operation of the new wells could introduce new sources of light into the vicinity of the project sites for these facilities, including night lighting. b. Could light or glare from the finished project be a safety hazard of interfere with views? It is anticipated that new above -grade facilities (i.e, well houses) would likely be located in urbanized areas already developed with structures and outdoor lighting. Any potential changes in the level, amount, or intensity of light and glare at the proposed project sites are not anticipated to result in a safety hazard or interfere with existing views. Future site-specific SEPA review for these proposed new facilities will address potential effects of light and glare in more detail. c.

The service area contains a large variety of recreational facilities and opportunities such as parks, rivers, and lakes. b. Would the proposed project displace any existing recreational uses? If so, describe. The proposed distribution mains and wells would not have any effects on recreational opportunities in the service area. Future site-specific SEPA review for implementation of the other proposed projects will provide information on potential impacts to recreational uses. It is anticipated that these projects would not have an adverse effect. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: Impacts to recreation would be reduced or controlled through the siting process for future planned projects. 13 HISTORIC AND CULTURAL PRESERVATION a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. The proposed distribution mains and well houses would be constructed in areas previously disturbed, and therefore it is not anticipated that construction activities for these projects would adversely impact any places or objects listed on or proposed for preservation registers.

TRANSPORTATION a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on-site plans, if any. Local streets will be used to access sites during construction of the Plan's proposed projects. Many local streets will be temporarily disturbed during installation of distribution mains; during construction periods, traffic may need to be re-routed to avoid construction activities. b. Is site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? Does not apply. c. How many parking spaces would the completed project have? How many would the project eliminate? Minimal parking would be required at the well sites. It is anticipated that implementation of the Plan's recommended projects and programs would not result in the elimination of any parking spaces. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). The need for new public access as a result of this Plan is unlikely. The new wells, WTP improvements, and distribution lines will be constructed in an urbanized area serviced by existing roads. It is anticipated that no new roads or road improvements would be required to service the new wells. However, public roads may be temporarily blocked and traffic diverted during construction of the proposed distribution mains. e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. Does not apply. f.

SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (do not use this sheet for project actions) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal, or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The Water System Plan Update in itself would not have direct impacts on the physical environment. However, the activities that may result from implementation of the Plan could result in possible short-term construction impacts or long-term site specific impacts. Although some recommendations of the Plan involve legal, political, or managerial actions which would not directly affect the environment, construction projects or operational changes that are a result of those actions might. The recommendations of the Plan do not suggest projects that would permanently or significantly increase discharges to water; discharge emissions to air; produce, store, or release toxic or hazardous substances; or produce significant amounts of noise. Air emissions (in the form of dust) and noise emissions would be generated during new facility construction. Noise emissions. Proposed measures to avoid or reduce such increases are: Construction impacts can be reduced by watering and replanting disturbed areas and monitoring the hours of operation within sound -sensitive areas. The recommended facilities that are capable of producing noise would most likely be located adjacent to similar existing water utility facilities or in an urbanized area (e.g., new wells). 2. How would the proposal be likely to affect plants, animals, fish, or marine life? Recommendations of the Plan would not be likely to affect plants, animals, fish, or marine life. The proposed distribution lines and contact basin building will be constructed in areas of previous disturbance. Further environmental analysis under SEPA will be conducted to determine if any site-specific impacts to these resources would result from implementation of other individual construction projects. City of Yakima. REC VED MAY 1 2017 CITY OF YAKIMA DIV May 3, 2017 18 Environmental Checklist Proposed measures to protect or conserve plants, animals, fish, or marine life are: The planning, design, and construction of facilities that have the potential for such impacts would incorporate features to reduce the likelihood of occurrence and significance. 3. How would the proposal be likely to deplete energy or natural resources? Some of the recommended facilities would require electrical energy, such as the new supply wells. However, this increase in energy demand would represent a small percentage of increase over that of the existing water system. As the demand for treated domestic water increases, more water would be withdrawn from the surface water and groundwater sources. Proposed measures to protect or conserve energy and natural resources are: High -efficiency electric motors will be used at the new wells. The Plan also includes on-going leak detection, water conservation, and corrosion control programs. 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands? Facility improvements and additions would not likely affect sensitive areas. To the maximum extent feasible, facilities will be sited to avoid sensitive areas. Any potential impacts associated with facility construction and operation in these areas will be addressed as part of subsequent site-specific SEPA review for individual projects not yet sited. Proposed measures to protect such resources or to avoid or reduce impacts are: The planning and design modifications would incorporate environmental protection features to reduce impacts associated with construction. Environmentally -acceptable construction methods would also be implemented to lessen potential impacts to shoreline areas. 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? City of Yakima. The recommended improvements to the water system would most likely be located at or near existing water utility facilities, or in existing urbanized commercial/industrial areas, thus reducing the likelihood of incompatible impacts on land use. Construction activities at the WTP would not alter the existing shoreline use at that site. It is anticipated that the projects recommended in the Plan would not displace any persons. In addition, projects that develop from implementation of this Plan would be done by existing City forces or by outside construction contracts. ( �ECEW ED MAY 1 , 2017 CICITY'O��Fpp Y�f�AKIMA PL I C"!V. May 3, 2017 19 Environmental Checklist Proposed measures to avoid or reduce shoreline and land use impacts are: Emphasis to locate new facilities at or near existing water utility locations would help to avoid land use and shoreline use impacts. Although planning requirements of public utilities are less restrictive than non-public projects, implementation of Plan recommendations would be subject to local planning review for compliance with land use compatibility, including applicable local land use ordinances, zoning regulations, and other possible approvals. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? It is unlikely that implementation of the Water System Plan Update would increase demands on transportation, public services, and utilities. However, the existing transportation system could be temporarily affected during construction of distribution lines; this construction activity may require rerouting traffic during pipeline installation in local roads. Proposed measures to reduce or respond to such demand(s) are: The Plan includes features that should have positive impacts on the quality and reliability of public services. The storage facilities improvements, WTP modifications, distribution improvements, and development of new groundwater supplies will improve fire protection services and the delivery of potable water in emergency situations. 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. City of Yakima. The Water System Plan Update should not be in conflict with existing environmental laws or requirements. Implementation of recommendations within the Plan would be subject to specific environmental review as required under SEPA. xiECEJYED MAY 1 , 20i7 CITY OF YAKIMA PLANPLAfa.4G DIV. Appendix B.

February 2016 Page 2 of 2 Water System Plan Consistency Review Documenting Consistency a) Land Use and Zoning The City of Yakima is currently in the update process for its Comprehensive Plan. Part of the plan involves modifying the Future Land Use map to minimize the number of designations from 10 to 7. The underlying zoning districts remain the same. Areas that received a new or modified Future Land Use designation as part of the update will be eligible to apply for a rezone after plan adoption. Applicable sections of the zoning and subdivision ordinance and/or comprehensive plan are as follows: YMC 14.15.020(B); YMC 14.20.090; YMC 14.20.100; YMC 15.01.030; Comprehensive Plan Land Use and Capital Facilities Elements. b) Growth Projections The 2040 growth projection for the Water System Plan and the 2040 Comprehensive Plan are the same — both plans show a 2040 population of 110,387. There is a slight difference in the 2015 estimate. The Water System Plan uses the Yakima County Population Estimate of 93,825 where the Comprehensive Plan uses the Office of Financial Management (OFM) estimate of 93,220. Either way there is more than sufficient capacity to meet our growth target.

The following comments will need to be addressed before the Department of Health (DOH) can approve the document: 1) The plan must include the stamp and signature of a professional engineer licensed in the State of Washington. Chapter 1 2) Please provide Figures 1-2 and 1-6 on 11"x17" paper, at a minimum. 3) Our records indicate that there are at least 12 other Group A water systems adjacent or near to the City of Yakima Water Division. The public water system identification numbers for these systems are: 07143, 99114, 71725, 70630, 42948, 46219, 01985, 27828, 62020, 05885, 85138, and 86280. Please ensure that each is included in the plan, that each receives proper notice and opportunity to comment. Please provide a discussion of any communications the City has had with these systems with regards to regionalization.

Mr. David Brown April 27, 2017 Page 2 Chapter 3 5) In Section 3.3.4, the plan states that lead gooseneck research and removal is planned to be completed by the end of 2016. Has this been accomplished? 6) With regard to Section 3.6.1 and Figure 3-9, please note the following, WAC 246-290-230(8) requires that booster pumps for individual services approved by the city must be "under the management and control of the purveyor." In addition; • State that no new services may be connected above the 1460' level unless the City intends to create a new pressure zone for this area. • The Water System Design Manual (Section 10.0.3) identifies interim as 6 -years, which coincides with the approval of the Comprehensive Water System Plan. 7) The detail provided under Section 3.7.4 for the identified distribution related improvements (Pages 3-69 through 3-96), shows the location of the pipe and connections / services improved by the project. a) It appears from the information provided the distribution related projects that include the removal of the lead oakum joints are not considered a high priority. Is the city conducting lead and copper testing within this area, and are the levels being shown indicating no to minimal impact to the services being tested? The lead and copper testing completed by the city does not indicate an exceedance of the Action Level for Lead. b) Did the city locate and identify the services impacted by the low pressures identified in the hydraulic analysis and confirm whether they were or had experienced low water pressures? Figure 3-14 indicates a small area impacted above and just outside the 3rd Level Boundary with low pressure. c) Did the city locate and identify the services impacted by the high pressures identified in the hydraulic analysis and confirm whether they are experiencing high water pressures? Figure 3-14 indicates several nodes along the 1st Level and 2nd Level Boundaries with high pressure. Chapter 4 8) The Department of Ecology has issued a comment letter regarding this submittal.

She also invited me to send any additional comments to you, so I'm providing the following comments for consideration: 1. On page 1-25 under Northwest Boundary (Gleed) the description of the location of the UGA boundary doesn't appear to be correct. For instance, it says "The urban growth boundary shown in Figure 1-5 coincides with Maple Way Road," which isn't accurate (neither the Figure 1-5 part nor the Maple Way Road part). I suspect that this language dates from 1994-1996 when the Interim UGA boundary did extend to Maple Way Road. Agreed. The text on page 1-25 has been updated to correctly describe the UGA boundary. 2. The following areas appear to be within Yakima's service area per Fig. 4-1 (and other Figures that depict Yakima's service area) but for which Zoning (Fig. 2-3) and Future Land Use (Fig. 2-4) are not indicated: • West of 40th Ave and north of SR 12; • North of W. Powerhouse Rd., South of SR 12, between Ackley Rd. and the Mobile Home Park; • Southeast of Peck's Canyon Rd; • Parcel 18131612422 and vicinity; • Parcel 18131631402 and parcels to the south and east thereof. Figures 2-3 and 2-4 have been updated to not clip the zoning and future land use areas. The full extent of available zoning and future land use data is now shown on these figures. Copies of the updated figures are attached. 1 3. The area south of Naches River, west of Fruitvale canal, and north of the Naches rail trail is indicated by several Figures as not being within Yakima's service area. Is this correct? And if so does Yakima plan to ever provide water service to this area? This is correct. The City does not intend to serve this area at this time. Feel free to contact me with questions or comments.

TITLE: A Resolution authorizing the City Manager to execute a Memorandum of Understanding for the purpose of insuring the cost effective and best use of water resources for future development in the Yakima Valley SUB ITTED BY: Dave Zabell, Assistant City Manager Dave Brown, Water/Irrigation Manager CONTACT PERSON/TELEPHONE: Dave Brown / 575-6204 SUMMARY EXPLANATION: Water resource management and its relationship to future development in West Valley and other parts of the City has been discussed with the Council, Yakima County, Nob Hill Water Association, Yakima Valley Canal Company, Yakima Tieton Irrigation District and the Central Washing Home Builders Association. Of primary concern is that irrigation water traditionally used for agriculture from the canal companies and irrigation districts may not be put to full use as housing replaces agriculture. Additionally, where water to irrigate lawns at these new homes is supplied from municipal sources, like Nob Hill Water Association, those municipal water rights would be used up faster limiting future availability. A Memorandum of Understanding has been developed to formalize the actions necessary to maximize the water resources in and around the City of Yakima to ensure long-term availability and the most cost effective use of water resources. The memo previously provided to Council on November 28, 2007 about these discussions is attached.

BOARD/COMMISSION RECOMMENDATION: • COUNCIL ACTION: Adopt Resolution • DATE: TO: November 28, 2007 The Honorable Mayor and Members of the City Council FRO. r" Dick Zais, City Manager Dave Zabell, Assistant City Manager Dave Brown, Water/Irrigation Manager RE: Water Resources and Development in West Valley The subject of water resource management and its relationship to development in West Valley and other parts of the City has been discussed with the Council Economic Development Committee and was presented to the full Council at their April 24, 2007 Study Session. Of primary concern is that irrigation water traditionally used for agriculture from the canal companies and irrigation districts may not be put to full use as housing replaces agriculture. In Washington State, there is much case law to support that water not being put to its full beneficial use is subject to relinquishment — "use it or lose it". Additionally, where water to irrigate lawns at these new homes is supplied from municipal sources, like Nob Hill Water Association, those municipal water rights would be used up faster limiting future growth. Attached is an outline of the issues discussed with Council. These conditions demonstrate that coordinated resource management of water rights is in the long-term interest of the City of Yakima, Nob Hill Water Association, the various irrigation districts and canal companies serving our community, as well as the general public. Much has occurred over the months since Council was last briefed on this issue. City representatives have collaborated with Nob Hill Water Association, Yakima Valley Canal Company, Yakima Tieton Irrigation District, and the Central Washington Home Builders Association to address the issue of water resources in a comprehensive manner. Councilmembers McClure and Lover have participated in this effort. Issues, options, and resolutions discussed to insure continued use of the irrigation and irrigation district water rights were varied and included: • Enacting development rules that require developers to install separate irrigation infrastructure in which the City would own and operate the new systems • Enacting development rules that require developers to install separate irrigation infrastructure and have Nob Hill Water own and operate the new systems • Enacting development rules that require developers to install separate irrigation infrastructure and have the canal company or irrigation district own and operate the new systems • Enacting development rules that require developers to install separate irrigation infrastructure and have home owner associations own and operate the new systems (this is currently being done now in many developments) • Transferring water rights that were used for irrigation to Nob Hill Water so the water could be provided through their municipal water system (Nob Hill Water supplies the domestic - municipal water for West Valley) • Transferring water rights that were used for irrigation to the City of Yakima so the water could be provided to the Nob Hill Water municipal water system via intertie(s) • Nob Hill Water would require developers to install separate irrigation infrastructure as a condition of receiving municipal -domestic water from Nob Hill Water and Nob Hill Water would own and operate the new systems • Through cooperative agreements and cost sharing between Nob Hill Water • developers, developers would install separate irrigation infrastructure and Nob Hill Water would own and operate the new systems We are pleased to report that a tentative final resolution has been achieved. After several discussions, it was decided that a cooperative agreement and cost sharing program with Nob Hill water and the developer(s) is the best solution. Developers will install separate irrigation infrastructure and Nob Hill Water will own and operate the new systems eliminating the need for new development regulations. The, first agreement that will serve as a model for other developments is currently in affect between Nob Hill Water Association and Cottonwood Partners. The City of Yakima, Yakima County, Nob Hill Water Association, Yakima Tieton Irrigation District and Yakima Valley Canal Company are in the process of developing a Memorandum of Understanding (MOU) which will outline the issues and define the roles of each entity. The Central Washington Home Builders Association will be providing input for the development community. The MOU will be presented to Council for approval at the appropriate time. This will insure the water rights which have senior priority dates from the Canal Companies and Irrigation Districts will continue to be put to beneficial use. Nob Hill Water's municipal water rights will be available for additional future growth while maintaining maximum flexibility to determine the economics of an irrigation infrastructure system. This simple, yet elegant solution to a potentially 0 critical public policy problem is being accomplished without the need for new developm regulations, an approach which the development community has appreciated. • ©an RESOLUTION NO.

VICINITY MAP EXH.2/B7 MEMORANDUM OF UNDERSTANDING September 6, 2000 The purpose of this Memorandum of Understanding is to put in writing a verbal agreement and understanding between the City of Yakima Water/Irrigation Division and Nob Hill Water Association. This agreement is in regard to the service area boundary between the two domestic water systems and also the mutual aid arrangement between the two organizations involving water system interties. The City has prepared a City of Yakima Information Services GIS map dated September 5, 2000 which delineates the existing boundary between the two systems. Much of the area on each side of the boundary is already developed so the boundary in this area will not change. In areas which are not completely developed the proposed boundary line has been located in a place which has been mutually agreed upon. However, this line may be changed by mutual written agreement if it appears to be in the best interest of the City, Nob Hill Water and their customer(s). In line with the mutual aid situation the City and Nob Hill Water already have three interties between the two systems so that water can be transferred from one system to the other. This arrangement is for emergency purposes only and is not designed for normal operation of the systems. These interties have been used a few times in the past and have proven to be very beneficial. Consequently it appears to be in the best interests of both parties to continue this mutual -aid arrangement. NOB HILL WATER ASSOCIATION CITY OF YAKIMA Preston L. S epherd, P.E.

RESOLUTION NO. dJ—4376 A RESOLUTION adopting a statement of policy regarding the extension of City water and sewer services outside the corporate limits of the City of Yakima as such extensions affect annexation of unincorporated territory to the City of Yakima; and repealing Resolution No. D-791, adopted March 29, 1965. WHEREAS, the City Council of the City of Yakima desires to encourage the orderly growth and development of the fringes of the City where annexation of unincorporated territory is a logical extension of City boundaries so that development of newly annexed areas will conform to the General Plan of the City, and WHEREAS, the City Council further recognizes that land is rendered more valuable and desirable when water and sewer services are available to such land, and that the benefits of City water and sewer service should not be casually afforded to property outside the City, but rather that all property served by City water and sewer facilities should be within the city limits whenever and wherever possible, and WHEREAS, the City Council further recognizes that in many instances where City water and sewer service is sought for property out- side the City, the owners of such property desire to annex that property to the City but are prevented from doing so because of requirements of state annexation laws or other circumstances, but that in many such in- stances city water and sewer service should nevertheless be afforded to such property with conditions imposed which will lead to the annexation of that property to the city and which will otherwise enhance the value, safety and appearance of such property and the surrounding area, and which will, insofar as possible, insure land uses which conform to the City's General Pian, all as if such property were within the corporate limits of the City, Now, Therefore, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF YAKIMA: Section 1. The City Council of the City of Yakima does hereby adopt the following statement of policy regarding the extension of City water and sewer services to property outside the corporate limits of the City of Yakima, as such extensions are related to the annexation of such Y property to the City: 1. When such service is sought for property contiguous to existing city limits, and the size of the property is suffici- ently large to merit its annexation, in the opinion of the Director of Planning and Community Development, the annexa- tion of that property to the City shall be a condition of its receiving such service. 2. An application for such service to property outside and adjacent, but not contiguous, to existing City limits will be granted only after it has been determined that it is impractical or not feasible to annex that property to the City within the near future, and only under circumstances which will allow the development of that property to be controlled by city codes, regulations and policies, all as if such property were within the City. 3. Applications for such service shall be made to the Depart- ment of Planning and Community Development. If the Director of that Department determines that such service should be afforded, he shall so recommend and report his findings to the City Manager. Applications for utility services to property whose use and/or development has significant effect upon community development as prescribed in the General Plan of the City shall additionally be referred to the Planning Commission for their review and recommendations. Each application shall be granted only upon approval by motion of the City Council. In the event the City Council decides that any such application should be granted, the City Council may attach conditions to the granting of such application as the City Council deems advisable under the circumstances surrounding that application, which conditions shall include the execution by the owners and occu- pants of the property of an Outside Utility Agreement, a copy -2- s 1 of which is attached to this Resolution and made a part hereof. The alterations, improvements, or repairs referred to in paragraph 2 of that agreement arc required in order that structures served outside the City in anticipation of future annexations will reasonably conform to applicable construction and zoning codes. Provisions of paragraph 2 are applicable only to structures built within the last two years. The require- ments, restrictions and other provisions referred to in paragraph 4 of that Agreement may include, but need not be limited to, references to subdivision plat maps, site plans, utility maps and other similar development plans which, together with other obligations specified in that Agreement, will consti- tute conditions of the granting by the City of the application. 4. If the property for which such service is sought is developed and improved at the time of application, conformity to the City's General Plan, and conformity with building, zoning and other codes, regulations and policies of the City with regard to that development, will be considered as a persuasive factor for the granting of the application. 5. The filing of an application for such service prior to constructing any buildings, structures or other improvements thereon, or any other development thereof, will be considered as a persuasive factor for granting such application. 6. The existence of a City utility service line adjacent to developed property for which such service is sought will be considered as a persuasive factor for granting an application; however, property situated where no such utility service line exists adjacent to it will normally be required to constitute a Local Improvement District, or part of the area of a Local Improvement District which must be created to finance the extension of a utility line to serve an area of an appropriate size -3- • • and shape for annexation to the City, and the commence- ment of proceedings to annex that area will normally be a condition of the granting of an application for such service. 7. Inasmuch as utility service will be extended to property outside the City limits only when such property is subject to City codes, regulations and policies, all as if that property were within the City, an application for such service will be submitted by the Director to the Planning Commission of the City of Yakima for its review and recommenda- tion to the City Council in the case of subdivision plat approval ANA in case of land use differing from that contemplated by the City's General Plan. While subdivision plat maps for property outside the City must be approved by Yakima County by law, nevertheless, any such preliminary plat map must be reviewed and approved by the City Planning Commission before final approval by Yakima County, if the property in that subdivision is to be served by City utilities. The approval by the City Planning Commission of the plat map may be subject to requirements, restrictions and provisions as conditions of the granting by the City of the application for such services. Section 2. The foregoing statement of policy is intended to be gen- eral in scope and advisory only, and is not intended to be a limitation on the exercise of discretion and judgment by the City Council on any occasion when an application for City water or sewer service is made.

Through this letter, as the local fire protection authority, I authorize the nesting of standby and fire suppression storage for all pressure zones in the water system. Sincerely, Bob Stewart Fire Chief "The Yakima Fire Department is dedicated to providing quality public safety services to our community." This page left intentionally blank.

System Description a) Hydraulics The City of Yakima water system is normally served by the Naches River WTP with the Naches River as the source. About three miles downstream from the Plant is the Gleed system and this is our first customer. CT is calculated from this point. Treated water from the Plant is conveyed by gravity in a 48" concrete pipe to the 1st pressure zone and fills the 6MG reservoir. Water is normally pumped to the 2nd zone reservoirs and to the 2nd zone distribution system directly from the 40th Avenue pump station. Stone Church Pump Station is a backup / supplemental facility and delivers to the 2nd zone distribution system. The 3rd Level pump station is located at the 2nd zone reservoirs and pumps to the 3rd zone distribution system and 3rd zone reservoirs. System head is provided within a range for all three pressure zones by maintaining elevation in the reservoirs. The Gleed pressure zone is hydropneumatic. b) Pressure Reducing Valves The pressure zones are connected but isolated from each other by Pressure Reducing Valves and closed valves. The PRV's are set to open at specific downstream pressure setpoints, and are intended for emergency use only. See table 1.d c) Wells The four wells were designated seasonal sources in 2009 and are used in emergency and supplemental situations to support the WTP. Airport (S02), Kiwanis (S03), and Kissel (S08) are fixed output (dependent on system head) while Gardner (S10) can be controlled by variable frequency drive in local or remote modes. Kissel and Gardner are also ASR wellheads. d) Interties The interties with Nob Hill Water Co. are used only in the most extreme of circumstances, typically when very high demand and unexpected maintenance issues occur simultaneously. 4.

System Description a) Hydraulics The City of Yakima water system is normally served by the Naches River WTP with the Naches River as the source. About three miles downstream from the Plant is the Gleed system and this is our first customer. CT is calculated from this point. Treated water from the Plant is conveyed by gravity in a 48" concrete pipe to the 1st pressure zone and fills the 6MG reservoir. Water is normally pumped to the 2nd zone reservoirs and to the 2nd zone distribution system directly from the 40th Avenue pump station. Stone Church Pump Station is a backup / supplemental facility and delivers to the 2nd zone distribution system. The 3rd Level pump station is located at the 2nd zone reservoirs and pumps to the 3rd zone distribution system and 3rd zone reservoirs. System head is provided within a range for all three pressure zones by maintaining elevation in the reservoirs. The Gleed pressure zone is hydropneumatic. b) Pressure Reducing Valves The pressure zones are connected but isolated from each other by Pressure Reducing Valves and closed valves. The PRV's are set to open at specific downstream pressure setpoints, and are intended for emergency use only. See table 1.d c) Wells The four wells were designated seasonal sources in 2009 and are used in emergency and supplemental situations to support the WTP. Airport (S02), Kiwanis (S03), and Kissel (S08) are fixed output (dependent on system head) while Gardner (S10) can be controlled by variable frequency drive in local or remote modes. Kissel and Gardner are also ASR wellheads. d) Interties The interties with Nob Hill Water Co. are used only in the most extreme of circumstances, typically when very high demand and unexpected maintenance issues occur simultaneously. 4. DBP Sampling Accredited Laboratory for DBP Analysis: Edge Analytical Laboratories Inc 1620 S Walnut St, Burlington WA, 98233 phone: (800) 755-9295 Number of Distribution Samples Required: 8 (The City of Yakima does not qualify for reduced monitoring due to at least one LRAA above the 40/30 threshold.) Distribution System Sampling: The IDSE Report for Standard Monitoring approved by EPA on 6/25/2009 established the sites and schedule for sampling of DBP's under the new Stage 2 rule. The following table lists the sample locations and rationale for selection. Z-49, St. Timothy's Church 4105 Richey Rd Highest TTHM KW -1, Kissel Well 32nd Ave x Mead Ave Highest HAA5 (S1 site) L3PS, 3rd Level Pump Station City Reservoir Rd 2nd Highest HAA5 (S1 site) Z-13, Yakima Eye Care 506 N 40th Ave 2nd Highest TTHM X-44, Deccio Building, Fairgrounds 1301 S Fair Ave 3rd Highest TTHM WWTP, Wastewater Plant 2201 E Viola Ave 3rd Highest HAA5 (S1 site) Z-45, ARCO 1801 E Nob Hill Blvd 4th Highest TTHM CR -1, Creekside Realty 3907 Creekside Lp 4th Highest HAA5 The schedule is quarterly, beginning November, 2012. Sampling is scheduled for the week the 23rd of February, May, August, and November of each calendar year. TOC samples are obtained from the raw water and from an individual filter effluent once each month and are paired with an alkalinity measurement from the same day. 5. Compliance Compliance for DBP's under the Stage 2 rule is calculated for each site using a Locational Running Annual Average (LRAA). Quarterly samples are averaged with the three previous quarterly samples at each location to determine the LRAA for each of the 8 sample sites. LRAA's above 80 ppb for TTHM's and 60ppb for HAA5's are a violation of the MCL. Compliance for chlorine MRDL is calculated from averaging all distribution chlorine residual samples taken each month. This includes all 70 coliform monitoring samples and samples reported from three other locations: the WWTP, City Hall, and the Kary Annex. An average above 4.0 mg/I is a violation. Compliance for TOC reduction is not required due to Naches River source water containing less than 2.0 mg/I TOC as calculated quarterly by RAA (running annual average).

Coliform Sampling Accredited Laboratory for Coliform Analysis: Cascade Analytical, Inc 1008 W Ahtanum Rd, Union Gap WA, 98903 phone: (509) 452-7707 Number of Distribution Samples Required: 80 distribution, 8 raw water Groundwater: The City of Yakima voluntarily samples each well once quarterly, whether in regular use or not, from a pre -chlorination tap in order to establish a long baseline of coliform negative sample results. Since January 2008 Airport (S02), Kiwanis (S03), and Kissel (S08) have consistently tested negative. Gardner (S10) has consistently tested negative since its commissioning in November 2011. Only Gardner (S10) could qualify for compliance monitoring under the Groundwater Rule, but the City chooses to treat it as the others and will rely on triggered monitoring when a positive coliform distribution sample occurs. Groundwater Rule (GWR) Triggered Monitoring: If a routine distribution sample is total coliform positive (TC+) the City shall sample, from the pre -chlorination tap, all wells running within three days prior to the day of the original positive sample. If a well is TC+ the City shall notify and confer with the DOH within 24 hours to determine a course of action. If a well is E. coli positive (EC+) then the City shall notify DOH the same day, and in addition to corrective actions issued by DOH, Public Notification must be made within 24 hours. Distribution System Monitoring: If any of the 80 routine distribution samples are total coliform positive (TC+), then within 24 hours the City will re -sample the original location and at least two more locations: one upstream and one downstream, within 5 services if possible. If any of the repeat samples are TC+, then the City may conduct a Level 1 Assessment, even if it does not meet the 5% threshold (<4 TC+ samples in same month). If repeat samples are TC+ and add up to more than 5% (>4) then the City shall conduct a Level 1 assessment. All TC+ samples will be further evaluated for E. coli, in every occurrence and circumstance, and if present then the City shall notify DOH the same day. Failure to perform EC analysis following a routine sample TC+ is a monitoring violation and requires a Tier 3 Public Notification. The following table lists the combinations for an E. coli MCL violation as per the RTCR. Routine Sample Repeat Sample EC+ TC+ EC+ Any missing sample EC+ EC+ TC+ EC+ TC+ TC+ with no E. coli analysis An E. coli MCL violation will result in a Level 2 Assessment to be performed by DOH or a DOH -approved entity. Distribution System Sampling: Routine distribution sampling is performed by Cascade Analytical Inc. of Union Gap, WA. The City has chosen to use one regular bank of 80 sample sites in response to the difficulty in keeping two 80 sample banks that alternate monthly. Table a.) are the best sample sites based on geographical representation, stability of occupancy, ease of sampling, and access. The alternate / repeat sites (table b.) are former regular sites and will for now keep their old naming convention. All sites in either table are valid as regular or repeat sampling locations at the discretion of the sampler provided geographical representation is maintained. The new numbering convention is sequential with the first digit corresponding to the pressure zone in which it is located. The colors correspond to a week during the month in which the sampling occurs: week 1 is purple, week 2 is orange, and week 3 is green. The red locations are sampled by City personnel. The blue locations are alternate / repeat sample sites. Each pressure zone is sampled at least once per sampling week, with the exception of Gleed which is quite small. A map is provided after the tables. a.)

Public Notifications Tier 1 notification is required within 24 hours of repeat sample EC+ confirmation or another EC+ MCL violation. Tier 1 PN's are to be performed within 24 hours. Tier 2 notification is required within 30 days of a treatment technique (TT) violation, defined as failure to perform a Level 1 or Level 2 assessment and/or failure to perform measures recommended by an assessment. Tier 3 notification is required within a year of a monitoring or reporting violation. Examples are failure to report an EC+ sample as required and failure to submit an assessment. 6. Assessments Level 1 assessments are triggered when more than 5% (>4) of routine and repeat samples are TC+ in the same month, or failure to collect 3 repeat samples after a routine TC+ sample. Any knowledgeable person can perform a Level 1 assessment. Level 2 assessments are triggered when there is an EC MCL violation or when there are two Level 1 assessments within a rolling 12 month period. Only DOH qualified persons can perform a Level 2 assessment. Both Level 1 and Level 2 assessments must be performed and submitted to DOH within 30 days of the triggering event. Guidance for conducting Level 1 and Level 2 Assessments will be provided by DOH.

System Description a) Hydraulics The City of Yakima water system is normally served by the Naches River WTP with the Naches River as the source. About three miles downstream from the Plant is the Gleed system and this is our first customer. CT is calculated from this point. Treated water from the Plant is conveyed by gravity in a 48" concrete pipe to the 1st pressure zone and fills the 6MG reservoir. Water is normally pumped to the 2nd zone reservoirs and to the 2nd zone distribution system directly from the 40th Avenue pump station. Stone Church Pump Station is a backup / supplemental facility and delivers to the 2nd zone distribution system. The 3rd Level pump station is located at the 2nd zone reservoirs and pumps to the 3rd zone distribution system and 3rd zone reservoirs. System head is provided within a range for all three pressure zones by maintaining elevation in the reservoirs. The Gleed pressure zone is hydropneumatic. b) Pressure Reducing Valves The pressure zones are connected but isolated from each other by Pressure Reducing Valves and closed valves. The PRV's are set to open at specific downstream pressure setpoints, and are intended for emergency use only. See table 1.d c) Wells The four wells were designated seasonal sources in 2009 and are used in emergency and supplemental situations to support the WTP. Airport (S02), Kiwanis (S03), and Kissel (S08) are fixed output (dependent on system head) while Gardner (S10) can be controlled by variable frequency drive in local or remote modes. Kissel and Gardner are also ASR wellheads. d) Interties The interties with Nob Hill Water Co. are used only in the most extreme of circumstances, typically when very high demand and unexpected maintenance issues occur simultaneously. 4. Monitoring Continuous Monitoring: The WTP continuously monitors Individual Filter Effluent (IFE), combined filter effluent (CFE), and raw water for turbidity. The WTP continuously monitors pH and chlorine residual at two points in order to calculate two CT requirements and ratios to arrive at a final inactivation ratio. The WTP continuously monitors fluoride residual at two points to determine feed rate accuracy, and is provided fluorine residual via SCADA at Gardner Well (S10) to determine feed rate accuracy while the Well is running. The WTP is provided continuous free chlorine residual in the distribution system via SCADA by online analyzers located at the following points: Gleed CT Facility 3211 Mapleway Rd 3rd Level Pump Station 1310 Reservoir Rd Airport Well 2007 W Washington Ave Kiwanis Well 1103 E Maple St Kissel Well 32nd Ave x Mead Ave Gardner Well Pierce St x Cornell Ave Free chlorine residual grab samples are analyzed by City staff nominally once per workday at three locations in the distribution system: Kary Annex 2301 Fruitvale Blvd City Hall 129 N 2nd St WWTP 2220 E Viola Ave Weekly Analysis: WTP staff analyze raw and treated water once weekly for alkalinity and CFE for calcium equivalent hardness.

In addition to disclosing the results of our major testing programs, we hope this letter will inform you about your tap water and inspire confidence that the water we all rely on is of the highest quality possible. In pursuit of that goal the Water/Irrigation Division staff is committed to around-the-clock vigilance and service, and we are proud to announce that your tap water meets and ex- ceeds all state and federal requirements. WHERE YOUR WATER COMES FROM The Naches River supplies most ofYakima's drinking water. Our diversion is located along Hwy 12 and supplies the Naches River Water Treatment Plant at Rowe Hill. After treatment, water flows by gravity along the highway into town. During times of heavy runoff or when the Plant requires downtime maintenance, we can draw upon our 4 wells. They are located at Kiwanis Park, Kissel Park, Gardner Park, and Yakima Airport. These wells draw from the Ellensburg Aquifer and are also tested regularly. 1 Every year we take hundreds of samples and analyze them for disinfection byproducts, syn- thetic and volatile organics, biological, radiological, and inorganic contaminants The tables below show the most important and frequently requested results for 2015 If you have any questions about these tests or if you would like to know about a substance not listed here you can call the Water Quality Specialist at 509-576-6477. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and poten- tial health effects can be obtained by calling the Environmental Protection Agency's Safe Drink- ing Water Hotline at 1-800-426-4791 Microbial Contaminants Each year 840 samples from the distribution system are collected and analyzed to comply with the Total Coliform Rule (TCR). Coliforms are environmentally ubiquitous bacteria that live in the ground. The presence of coliforms in the water may indicate a leak, a cross -connection, or other problems. Name Units Total Coliform Sample MCL MCLG Number detected >5% 0 0 Range low/high Violation? 0-100% No Disinfection and Disinfection Byproducts Disinfection Byproducts (DBP's) are formed when the chlorine added as a disinfectant combines with the naturally occurring organic matter (NOM) to form potentially harmful compounds.

Immuno -compromised per- sons such as persons with cancer undergo- ing chemotherapy, persons who have un- dergone organ transplants, people with HIV/AIDS or other immune system disor- ders, some elderly, and infants can be par- ticularly at risk from infections. These peo- ple should seek advice about drinking wa- ter from their health care providers. EPA and the Center for Disease Control guide- lines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800 -426-4791). 3 About Lead in Drinking Water If present, elevated levels of lead can cause seri- ous health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and compo- nents associated with service lines and home plumbing. The City of Yakima is responsible for providing high quality drinking water, but can- not control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure to lead by flush- ing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (800) 426-4791, or http://www2.epa.gov/lead Every three years the City of Yakima is required to analyze water samples from homes determined by the EPA to be most susceptible to lead and copper leaching from pipes and plumbing components. The City of Yakima is very pleased to present the 2015 results of all these analyses here. The element abbreviation for lead is Pb, Lead and and copper is Cu. All values are mg/L, or PPM. The Rule sets an Action Level (AL) for lead at 0.015 mg/L and 1.3 mg/L for copper. As you can see, all of these locations from throughout our service area show very low to Copper Rule essentially undetectable amounts of these harmful metals.

The Department of Ecology issued a Temporary Permit for operation of the City's ASR system on February 24, 2015 (2015 Permit) This report details the City's operation of the ASR system under the 2015 Permit from February 24, 2015 through the end of Water Year (WY) 2015 (October 1, 2014 — September 30, 2015). The City's WY 2015 operations are summarized as follows • A total of approximately 41 million gallons (125.1 acre-feet) was recharged to the aquifer via the Gardner Well during two periods of recharge in March and April 2015 No other wells were used for recharge • No stored water was recovered under the ASR program Stored water is reserved for future recovery as provided in the 2015 Permit. Of the 125.1 of recharged in WY 2015, 100.1 af would be available for recovery in WY 2016 (80% of WY 2015 recharge volume) • No discharge to surface waters occurred. • Monitoring of disinfection byproducts (DBPs) in both source water (i.e., water being recharged into ASR wells) and stored water (i e , water withdrawn from ASR wells) was conducted as required by the 2015 Permit While water quality sampling frequency generally complied with the 2015 Permit, refinements to the sampling schedule are recommended for WY 2016. • Water quality results in some instances exceeded the 2015 Permit limits for source water (1/2 the current drinking water limits for DBPs) However, water quality results were in compliance with drinking water standards in all samples (i e , in both source water and stored water) at all times. • Routine pumping of the Gardner Well from May through September under existing groundwater rights resulted in the withdrawal of approximately 1,260 af, which is substantially more water than was recharged during March and April • As of June 3, at which time approximately 340 af of water had been withdrawn from the Gardner Well after the end of recharge, DBPs had dropped to very low levels, indicating that the majority of DBPs introduced during recharge had been removed. To address the water quality issues experienced in WY 2015, the City is preparing a set of Standard Operating Procedures (SOPs) for the ASR program. The SOPs will address procedures such as confirmation testing of source water before recharge begins; ongoing review of sampling data during recharge, action levels for increasing monitoring frequency or terminating recharge, contingency plans, and coordination with Ecology The City will provide the SOPs to Ecology for its review before beginning recharge in WY 2016. The City also requests the opportunity to consult with Ecology to develop a more readily implementable schedule for sampling source water during recharge, such as sampling after recharging every 1,000 af of water, or sampling every two months. Yakima ASR Program 1 WY 2015 Annual Report 1.0 Introduction The City of Yakima (City) has developed an Aquifer Storage and Recovery (ASR) program to provide additional water supply and improve water system reliability The ASR program involves diverting water from the Naches River during low demand periods (e.g., the winter), treating the water to drinking water standards, delivering water through the City's distribution system to groundwater wells, and injecting (recharging) water through the wells into the aquifer (reservoir) Groundwater may then be withdrawn at later times for municipal use The City's ASR program has been developed through extensive feasibility studies (Golder 2000, 2001, 2009, 2014a, 2014b, 2014c, and 2015). Additional technical information regarding the ASR program can be obtained from these studies The City submitted Reservoir Permit Application R4-3552 to the Washington Department of Ecology (Ecology) on April 12, 2002. The proposed storage reservoir was the Upper Ellensburg aquifer in the Ahtanum-Moxee subbasin. Development and final permitting of this storage reservoir is being coordinated with the Yakima River Basin Integrated Water Resources Management Plan (Integrated Plan) The goals of the Integrated Plan are to protect, mitigate and enhance fish and wildlife habitat; provide increased operational flexibility to manage instream flows to meet ecological objectives; and improve the reliability of the water supply for irrigation, municipal supply and domestic uses (Reclamation and Ecology 2012b) A Temporary Reservoir Permit (2015 Permit, Appendix A) was issued by Ecology on February 24, 2015 for beneficial use of the groundwater reservoir while Ecology completes processing the application under WAC Chapter 173-157. The 2015 Permit will remain in effect until January 1, 2017 The City began recharge operations on March 10, 2015 under the conditions of the 2015 Permit This report summarizes the first year of ASR operations performed by the City through Water Year (WY) 2015 in accordance with the 2015 Permit. The 2015 Permit references and is based largely on the Technical Memorandum (Golder, 2014c) The Technical Memorandum outlines the various elements of the ASR program and includes a specific project operation plan, legal framework, and environmental analysis. The 2015 Permit provides that all ASR activities shall comply with the Technical Memorandum except as otherwise specified in the Permit or authorized by Ecology Key aspects of the 2015 Permit and Technical Memorandum to consider for ASR operations and annual ASR reporting include • Pilot Phase: The Technical Memorandum describes a 5 year Pilot Phase, at the end of which Ecology would evaluate the program's operation and could modify conditions of the permit, if warranted The 2015 Permit provides that it is "associated with the Pilot Phase". • Points of Recharge and Recovery Under the 2015 Permit, water may be recharged at the City's Kissel and Gardner wells, and stored water may be recovered from any of the City's existing wells (i.e., Kissel, Gardner, Kiwanis, or Airport wells). The location of Yakima ASR Program 2 WY 2015 Annual Report these wells is shown on Figure 3-1. The Technical Memorandum addresses planned future ASR wells, which the City has requested be authorized in the final permit. • Recharge Rates and Volumes Under the 2015 permit, total recharge (at the Kissel and Gardner wells combined) may not exceed 4,000 gallons per minute (gpm) or 3,000 acre- feet per year (afy), respectively During the Pilot Phase described in the Technical Memorandum, recharge would be limited to 3,000 gpm per well with a combined maximum of 9,000 gpm, and 4,800 afy per well with a combined maximum of 9,600 afy. • Storage Volumes The 2015 Permit does not contain an express limit on total quantity that may be stored in the reservoir. However, total quantity is implicitly limited to approximately 6,000 af because the Permit, which limits annual recharge to 3,000 afy, is only effective for approximately 2 years (February 24, 2015 — January 1, 2017) During the Pilot Phase described in the Technical Memorandum, the maximum recoverable quantity that the City may hold in storage would be 50,000 acre-feet (af). The Technical Memorandum recommends that this quantity be reviewed and potentially modified after the Pilot Phase in light of the application's request for storage of up to 200,000 af • Recoverable Volume: The 2015 Permit provides that the recoverable volume of water is as outlined in the Technical Memorandum The Technical Memorandum in turn provides that recoverable volume is a pre -determined percentage of any given year's recharge volume, and is dependent on how long the water is stored. For each year that recharged water remains in storage, the quantity available for recovery decreases by 10% (see Table 2-3) Accordingly, recharge volumes that have been in storage for 1 year or less may be recovered at 90%, and recharge volumes that have been in storage for 10 years or more may not be recovered. The recoverable volume in storage is calculated each year based on recharge, withdrawal (if any) and duration of storage. So, for example, in Year 3 of the 2015 Permit, the City could recover 70% of the remaining Year 1 recharge, 80% of the remaining Year 2 recharge and 90% of the Year 3 recharge This assumes no withdrawal of storage occurs in Years 1 and 2. • Water Quality Criteria The 2015 Permit provides the following water quality criteria o DBPs in source water (i.e., water being recharged) shall not be higher than "1/2 of the current drinking water standard." The current drinking water standards are 80 ug/L for Total Trihalomethanes (TTHMs) and 60 ug/L for the five major Haloacetic acids (HAAS) Therefore the 2015 Permit criteria for source water are 40 ug/L for TTHMs and 30 ug/L for HAAS. The Technical Memorandum recommends the following water quality criteria: o Recharged water should meet drinking water standards at all times (i.e., in source water, stored water and recovered water). o The average of recharge water samples (i e , source water) within any recharge cycle should not exceed 50% of the drinking water criteria for TTHMs • Water Quality Sampling Schedule The 2015 Permit requires sampling of source water and recovered water (if any) based on a percent of the total recharge volume. The Yakima ASR Program 3 WY 2015 Annual Report sampling frequency prescribed in the 2015 Permit therefore effectively assumes that the total volume to be recharged during the annual recharge cycle is known before recharge begins The 2015 Permit also requires sampling of stored water 1 -month after recharge ends, which the City interprets as the end of the final recharge period for the water year, or when no recharge has occurred for 1 -month, whichever occurs first. The Technical Memorandum recommends that source water and stored water be sampled every two months, and that recovered water be sampled based on recovery of set percentages of the recharged water • Water Rights The 2015 Permit provides that the schedule, volume and rates of recharge, storage and recovery are as outlined in the Technical Memorandum. The Technical Memorandum in turn provides that the recoverable annual quantities of stored water are additive to the City's existing water rights Upon issuance of the final permit, the City intends to construct dedicated ASR wells that will recharge and withdraw water under the Reservoir Permit. The Technical Memorandum provides that the instantaneous quantities associated with these new wells will be additive to the City's existing groundwater rights, and that the annual quantities of water withdrawn from these dedicated ASR wells will be tracked against the recoverable quantities of stored water and will be additive to the City's existing rights. • Regional Stream Benefits The 2015 Permit and the Technical Memorandum both note that water recharged through the ASR program that is not recovered by the City will benefit streamflow in the Yakima River (termed "indirect recovery") The method of tracking and accounting for these in -stream benefits relative to any water allocation or Total Water Supply Available (TWSA) calculations has not yet been determined. Yakima ASR Program 4 WY 2015 Annual Report 2.0 Summary of ASR Operations 2.1 Background and Overview Source water for recharge is diverted under the City's existing surface water rights on the Naches River and then treated at the Naches River Drinking Water Treatment Plant (NRWTP). Treated water is conveyed to the ASR wells via the City's water distribution system Consistent with Department of Health (DOH) regulations, the City is currently preparing an updated Water System Plan (WSP) The WSP will include a detailed Operations and Maintenance (OM) manual for the City's entire water system, including the ASR program The OM manual will include operational protocols for the entire system, such as monitoring and controlling DBP precursors (e.g. organic matter) and chlorine residuals. It will also include protocols specific to the ASR program, such as water quality criteria for initiating and terminating recharge, and maintenance requirements for the monitoring network A draft WSP is expected to be submitted to DOH by October 2016 and finalized in early 2017. To address water quality issues experienced in WY 2015 under the 2015 Permit, and to institutionalize best management practices for the ASR program consistent with the Permit, the City is preparing a set of Standard Operating Procedures (SOPs) for the ASR program. The SOPs will address procedures such as confirmation testing of source water before recharge begins, ongoing review of sampling data during recharge, action levels for increasing monitoring frequency or terminating recharge; contingency plans; and coordination with Ecology. The City will provide the SOPs to Ecology for its review before beginning recharge in WY 2016. The final SOPs will be incorporated into the OM manual and WSP 2.2 Recharge and Storage Volume Recharge rates to the aquifer are controlled by pressure reducing valves (PRVs) and orifice plates that are installed on dedicated recharge by-pass piping at the Kissel and Gardner wellheads. Air release valves are included in the recharge bypass to minimize introduction of air to the aquifer The City adjusts PRV settings to control recharge rates as needed based on wellhead pressures, distribution system pressure, and other operational requirements Recharge and pumping volumes and rates are measured at the wellhead with dedicated Siemens MAG5000 inline flowmeters that report to the City's Supervisory Control and Data Acquisition system (SCADA system). The SCADA system records information at a 3 -minute interval (data can also be viewed in real-time). The SCADA data was processed at approximately 1 -hour intervals for presentation in this report Pursuant to the 2015 Permit, and as described in Section 7 3 of the Technical Memorandum, the processed SCADA data and all other pertinent data for WY 2015 collected as part of the Permit (e.g., water level, flow rate, temperature, pressure and water quality) are being provided to Ecology in electronic format. A total of approximately 41 million gallons (125.1 acre-feet) was recharged during two periods of recharge in WY 2015. As shown in Table 2-1, there was an initial 5 -day period of recharge (approximately 16 af) in mid-March followed by 26 days of recharge (approximately 109 af) in late -March through April Recharge occurred only at the Gardner Well, with a maximum Yakima ASR Program 5 WY 2015 Annual Report recorded instantaneous recharge rate of 1,368 gpm. The wellhead and distribution system performed well during WY 2015 and there were no leaks or other problems with the wellhead during recharge or storage Table 2-1. Summary of WY 2015 Recharge Quantities Recharge Period (WY 2015) Average Recharge Rate (gpm) Volume Recharged in ac ft (Mgal) Note Gardner Well 3/10 3/15 679 16 (5.22) Recharge interrupted due to elevated turbidity in source water 3/25 - 4/20 948 109 (35.53) Recharge resumed; average recharge rate was 697 gpm through 4/9 and 1,288 gpm through 4/20 Total Gardner Well Recharge 125.1 (40.8) Kissel Well No recharge at Kissel Well during WY 2015 Both Wells Total WY 2015 Recharge 125.1 (40.8) Recharge volumes were less than the anticipated volumes for WY 2015 because • The 2015 Permit was not issued until February 24, 2015, so no recharge could occur from October 2014 through February 2015 • The Kissel Well was not operable due to pump removal for replacement • Elevated turbidity in Naches River source water led to reduced capacity of the NRWTP and suspension of recharge on March 15. Recharge resumed on March 25 after turbidity levels subsided • Drought conditions resulted in curtailment of some of the City's surface water rights used for diversion of recharge source water, remaining surface water rights were needed for municipal supply after April 20, 2015 2.3 Recovery / Recoverable Quantity The 2015 Permit allows for recovery of recharged water at Kissel, Gardner, Kiwanis, or Airport wells. The City did not recover any of the stored water during WY 2015. All water recharged during WY 2015 is reserved for future recovery as provided in the 2015 Permit Table 2-3 shows the recoverable quantities as a function of storage time, as provided in the Technical Memorandum and incorporated in the 2015 Permit. For storage of 1 year or less, the recoverable quantity is 90% of the volume recharged. Accordingly, had the City recovered ASR water in WY 2015, it could have recovered 112 6 af (90% of 125 1 af recharged in WY 2015) Yakima ASR Program 6 WY 2015 Annual Report Because the City did not recover any stored water in WY 2015, the recoverable quantity of WY 2015 storage available in WY 2016 is 100.1 of (80% of 125.1 af). If the City does not withdraw any stored water in WY 2016, the recoverable quantity of WY 2015 storage available in WY 2017 will be 87 6 af (70% of 125 acre-feet) Table 2-3 tracks actual storage, recovery and recoverable quantity available by WY. It will be updated in each year's annual report. 2.4 Recharge Well Efficiency Well efficiency is an important operational parameter that will help determine when well maintenance is required It is also important in evaluating water -level responses in the recharge wells Well efficiency is estimated by calculating specific capacity (Cs), which is the recharge or pumping rate divided by the measured drawdown or water level rise at a specific time. A summary of observed specific capacities for the Gardner Well is presented in Table 2-2. Table 2-2. 1 -hour Specific Capacities (CS) for the Gardner Well Water Year �Y) Recharge Pumping w m• Notes Rate (gpm) (gpm/ft) gpm/ft (gpm) m (gpm/ft) gpm/ft � 20142 829 14.4 2,000 12.3 Measured during June step -test 1,550 13.1 3,200 11.7 Measured during June step -test 2015 670 13 1,470 12.8 1 Specific capacity (Cs) in gallons per minute per foot of drawdown from pumping (or buildup from injection) after approximately 1 hour of pumping or recharge. 2Testing completed during Gardner Well Pilot Test (Golder 2014b). The specific capacity data for 2015 are very similar to the observations in 2014 (Golder 2014b). Therefore, no significant reduction in well or aquifer efficiency has occurred since the last recharge cycle Yakima ASR Program 7 WY 2015 Annual Report Table 2-3.

This section presents the groundwater elevation data obtained from a monitoring network in place during WY 2015 The monitoring network includes each of the City's production wells (Gardner, Kissel, Kiwanis, and Airport Wells) and the Ahtanum Youth Park Well in Union Gap (Ahtanum Well, Ecology Well Log No 123858), which is a dedicated monitoring well Well locations are presented in Figure 3-1. Hydrographs for each well are presented in Figures 3-2 through 3-5 for WY 2015. During WY 2015, water -levels in City production wells and the Ahtanum Well were monitored with pressure transducers and data loggers (production wells report to the City's SCADA system). Monitoring well and pressure transducer information is summarized in Table 3-1. Pressure readings are corrected using a barometric pressure transducer housed at City offices A relational database including hourly water level and flow data for the City's production and monitoring wells is maintained in the City's files. The Gardner Well was the only well used for recharge operations during WY 2015 The following sections present the data obtained during WY 2015, including the recharge cycles. The hydrographs and figure numbers used in the discussion are summarized below. • Figure 3-1: Well Location Map • Figure 3-2 WY 2015 Hydrograph for City Production Wells (Gardner, Kissel, Kiwanis, Airport) • Figure 3-3: Recharge Cycle Hydrograph at Gardner and Ahtanum Wells (March -April 2015) • Figure 3-4 Recharge Cycle Hydrograph for City Production Wells (Kissel, Kiwanis, Airport) • Figure 3-5 WY 2015 Hydrograph for Ahtanum Well In general, seasonal water fluctuations are apparent in all wells during WY 2015, with static water -levels increasing from October 2014 to March 2015, and decreasing during the summer. These seasonal water level fluctuations are attributed primarily to minimal pumping of the aquifer during the winter, and higher pumping of the aquifer during the summer (e g , for irrigation and municipal uses by the City and other groundwater users) Water -levels began to increase in September at the end of WY 2015, most likely due to reduced pumping of the aquifer for irrigation and municipal uses.

Groundwater elevation varied between approximately 1,120 and 680 ft amsl during spring recharge and summer pumping, respectively The Gardner Well was pumped regularly from May through mid-September to meet municipal demand, averaging above 2,100 gpm A total of approximately 1,260 of of groundwater was withdrawn from the Gardner well between April 30 and September 11 under existing groundwater rights. The total production from the Gardner Well in WY 2015 was above average due to summer drought conditions The hydrograph in Figure 3-3 presents water -levels obtained from two pressure transducers installed in the Gardner well in WY 2015 These include a KPSI brand transducer that reports to the SCADA system and an INW brand transducer with internal data logging There are several characteristics to note in the hydrograph 1. Transducer Overpressure: The KPSI and INW brand transducers have maximum pressure ratings of 200 pounds per square inch (psi) and 300 psi, respectively The pressure rating of the KPSI transducer was exceeded when water -levels rose to approximately 1,085 ft amsl during recharge. In other words, the KPSI transducer cannot measure water -levels above 1,085 amsl. 2 Transducer Drift The two transducers do not produce the same water level responses Repeated over -pressurization of the KPSI transducer (e g during initial testing, Golder 2014b) may explain the deviation (drift) in water level readings between the two transducers. No manual water level measurements could be made to confirm this, due to an inability to access sounding ports 3 Data Gap There are two data gaps in the record for the INW transducer The first data gap, between March 10 and March 15, occurred because the transducer was not activated during the first recharge period. The second data gap, after April 2, occurred because the transducer malfunctioned 4 Recharge Flow Rates Injection flow rates are shown in blue on the Figure 3-3, with the right vertical axis for scale. Recharge flow averaged approximately 680 gpm from March 10 to March 15. Recharge resumed on March 25 at about 700 gpm and was increased to an average of approximately 1,300 gpm from March 29 through the end of recharge on April 8, 2015 The KPSI transducer was replaced at the end of WY 2015 with a new INW PT2X transducer (300 psi range), this should provide improved accuracy and reliability for water level monitoring during WY 2016. 3.2 Kissel WeII The hydrographs for the Kissel Well are presented in Figures 3-2 and 3-4. Figure 3-2 shows the water -levels for all of WY 2015 (October 1, 2014 to September 30, 2015) Figure 3-4 shows the water -levels during the Gardner Well recharge cycle from March 5, 2015 to April 23, 2015 In general, WY 2015 static water -levels in the Kissel Well increased from 1,030 feet above mean sea level (ft amsl) in October 2014 to about 1,060 ft amsl in March 2015, just prior to recharge at Yakima ASR Program 11 WY 2015 Annual Report the Gardner well. Static water -levels generally declined from 1,062 ft amsl in late April (as regional groundwater production in the vicinity of Yakima increased) to 1,010 ft amsl in late August Water -levels began to increase in September and were at about 1,027 ft amsl at the end of WY 2015 3.3 Kiwanis Well The hydrograph for the Kiwanis Well is presented in Figures 3-2 and 3-4. Figure 3-2 shows the water -levels for all of WY 2015. Figure 3-4 shows the water -levels during the Gardner Well recharge cycle from March 5, 2015 to April 23, 2015 In general, WY 2015 static water -levels in the Kiwanis Well increased from 1,070 ft amsl in October 2014 to about 1,085 ft amsl in March 2015, just prior to recharge at the Gardner well Static water -levels generally declined from 1,097 ft amsl in late April (as regional production increased) to about 1,056 ft amsl in late August. Water -levels began to increase in September and were at approximately 1,070 ft amsl at the end of WY 2015. 3.4 Airport Well The hydrograph for the Airport Well is presented in Figures 3-2 and 3-4 Figure 3-2 shows the water -levels for all of WY 2015 Figure 3-4 shows the water -levels during the Gardner Well recharge cycle from March 5, 2015 to April 23, 2015. In general, WY 2015 static water -levels in the Airport Well increased from 1,053 ft amsl in October 2014 to about 1,084 elevation in March 2015, just prior to recharge at the Gardner well. Static water -levels generally declined from about 1,084 ft amsl in late April (as regional production increased) to about 1,020 ft amsl in late August Water -levels began to increase in September and were at approximately 1,043 ft amsl at the end of WY 2015 3.5 Ahtanum Well The Ahtanum Well (also identified as the Ahtanum Youth Park or Youth Park Well) is a dedicated monitoring well located in the Ahtanum Youth Park, owned by the City of Union Gap. The Ahtanum Well has consistently responded to recharge and recovery testing at the City of Yakima's Kissel and Gardner Wells (Golder 2001, 2014c, 2015), which are located approximately 2.1 and 1.2 miles from the Ahtanum Well, respectively. Water -levels in the Ahtanum Well were monitored during WY 2015 using an INW pressure transducer with internal logging Although the Ahtanum Well is consistently responsive to recharge at Gardner, it is also affected by pumping at a nearby irrigation well for the Ahtanum Youth Park (well name unknown) and the City of Union Gap Well #6. The WY 2015 hydrograph for the Ahtanum Well is presented in Figure 3-5 The high frequency "chatter" in the hydrograph in October, April, and August/September is likely the result of pumping effects from the nearby irrigation well and/or City of Union Gap Well #6. The effect of pumping activities at these wells, as well as the effect of recharge at the City of Yakima's Gardner Well[s], on water -levels in the Ahtanum Well is described in the 2014 groundwater monitoring report (Golder, 2015). In general, WY 2015 static water -levels in the Ahtanum Well increased from about 1,013 ft amsl in October 2014 to approximately 1,020 ft amsl in March 2015, just prior to recharge at the Gardner well Water -levels increased about 1 25 feet during the second WY 2015 recharge period at Gardner until April 6, and then declined in apparent Yakima ASR Program 12 WY 2015 Annual Report response to nearby pumping. Static water -levels generally declined through the summer to about 1,006 ft amsl in mid-August. Water -levels were at elevation approximately 1,011 ft amsl at the end of WY 2015 3.6 Water Level Response to Recharge The Gardner and Ahtanum wells showed clear response to recharge during WY 2015 Water levels in the Kissel, Kiwanis, and Airport wells increased throughout the recharge period. However, it is unclear how much of this increase may be attributable to recharge vs. regional conditions, such as antecedent water level trends (e g recovery from pumping) and interference pumping from nearby wells 4.0 WATER QUALITY Under the 2015 Permit, water quality monitoring is required during recharge, storage, and recovery phases of the ASR program. The monitored water quality parameters are specific constituents of concern, which were identified through completion of an All Known, Available, and Reasonable Treatment analysis (AKART, Golder 2015a) The 2015 Permit establishes the criteria for water being recharged (i.e., source water) as being "1/2 the current drinking water limits for DBPs." The 2015 Permit does not specify the criteria for stored water or recovered water, indicating that these criteria are as set out in the Technical Memorandum, which requires that recharged water meet drinking water standards at all times, i e , during recharge, storage and recovery. Current drinking water standards only contain numeric criteria for two categories of DBPs, Trihalomethanes (THMs) and Haloacetic Acids (HAA). The numeric criteria are for Total THMs (TTHMs) and five HAAs (HAAS) Table 4-1 presents the TTHM and HAAS levels established in the 2015 Permit for source water (1/2 of drinking water limits) and for stored and recovered water (drinking water limits). Samples of source water were collected from a sample port at the Gardner Well wellhead by City staff, and analyzed by Edge Analytical in Burlington, WA, following EPA methods 524.2 and 552.2 for THMs and HAAs, respectively. Field parameters, including electrical conductivity (as specific conductance), pH, temperature, and residual chlorine were also collected during WY 2015 (Table D-2) Complete water quality results and laboratory QA/QC for WY 2015 are summarized in Appendix D. The frequency of sampling was initially proposed in the Technical Memorandum as shown in Table 4-2. The 2015 Permit prescribes sampling as a function of the percent of recharge volume, as shown in Table 4-3. The sampling frequency prescribed in the 2015 Permit effectively assumes that the total volume to be recharged during the annual recharge cycle is known before operations begin For example, for WY 2015, the City estimated when a "50% of recharge volume" would be achieved and collected a water quality sample on April 2, based on an anticipated 2015 total recharge volume of approximately 82 ac -ft. However more water was eventually recharged during 2015 (after April 2), so the April 2 sample actually corresponded to 33% of the WY 2015 recharge volume (Table 4-4) The sample corresponding to "100% of recharge volume" was collected on April 20, just prior to shutting down recharge. If the City had available water to recharge later in the year, further deviation from the volume targets for sample collection would have been observed Yakima ASR Program 13 WY 2015 Annual Report Operationally, the "percentage of recharge volume" sampling approach in Table 4-2 created some logistical difficulties that should be addressed for the WY 2016 sampling. The City requests the opportunity to consult with Ecology to develop a more readily implementable schedule for sampling source water during recharge, such as sampling after recharging every 1,000 of of water, or sampling every two months.

City staff collected three samples of source water from the Gardner Well during recharge (Table 4-4). The samples were collected at the wellhead prior to injection into the aquifer The 50% recharge volume sample was collected on April 2 based on an anticipated recharge volume of approximately 82 ac -ft. However more water was eventually recharged than anticipated, so the April 2 sample actually corresponded to 33% of the WY 2015 recharge volume. The sample corresponding to 100% of recharge volume was collected on April 20, just prior to shutting down recharge for WY 2015 Table 4-4.

The Technical Memorandum recommends a DBP compliance criteria based on "the average of recharge water samples within any recharge cycle". The values reported in Table 4-3 are not averages. The average of the TTHM values is 40.6 ug/L, and the average of HAAS values is 33 9 ug/L The intent of the criteria described in the Technical Memorandum is to ensure that water quality always meets drinking water standards Previous pilot tests indicated that DBPs continued to form after recharge and during storage (Golder 2001 and 2014b) Therefore, the water quality Yakima ASR Program 15 WY 2015 Annual Report criteria for recharge (source water) were established to provide an allowance for increase of concentrations during storage while remaining within safe drinking water standards. As discussed in the next section, the results of stored water sampling indicate that this objective was met — all recharged water samples met drinking water standards at all times To address the water quality issues experienced in WY 2015, the City is preparing a set of Standard Operating Procedures (SOPs) for the ASR program The SOPs will address procedures such as confirmation testing of source water before recharge begins; ongoing review of sampling data during recharge; action levels for increasing monitoring frequency or terminating recharge; contingency plans, and coordination with Ecology The City will provide the SOPs to Ecology for its review before beginning recharge in WY 2016 4.2 Stored Water Quality Water quality monitoring of stored water is required one month after the end of recharge Samples must be collected at each well used for recharge during the year. Recharge in WY 2015 only occurred at the Gardner Well. The recharge period ended on April 20, 2015. Water quality samples were collected from the Gardner Well on May 1 (11 days after recharge stopped) and on June 3 (44 days after recharge stopped) The samples were compared to regulatory drinking water standards (Table 4-1). The average storage period for the two samples (i e , May 1 and June 3) is approximately one month. The May 1 storage sample represents source water with an aquifer residence time of 11 days (pilot testing has indicated very little mixing occurs with native groundwater over this time period, Golder 2001, 2014b) As described previously, the City would like to consult with Ecology on how best to establish the sampling timing relative to recharge and storage periods for an annual recharge cycle (where there could be multiple recharge periods). Table 4-5. DBP Results for WY 2015 Storage (pg/L) Sample Date (WY 2015 Days since Recharge Stopped Haloacetic Acids (HAA5) Trihalomethanes (TTHMs) Total HAAs (HAA5) Stored Water Compliance Criterion2Criterion2 Total Trihalo- methanes (TTHMs) Stored Water Compliance Gardner Well 1 -May 11 44.3 60 53 2 80 3 -Jun 44 <1 1.4 1 Represents days since April 20, the second recharge period of WY 2015 2 Drinking Water Standard Water quality of stored recharge water met drinking water criteria at all times. The HAAS concentrations increased from 31.9 ug/L in source water on April 20 (when recharge stopped) to 44 3 ug/L on May 1 (11 days of storage) The TTHM concentrations increased from 32 9 ug/L in source water on April 20 (when recharge stopped) to 53 2 ug/L on May 1 These increases in DBP concentrations are likely associated with continued reaction of residual chlorine with organic material that is present in the aquifer and/or source water. This is consistent with results of ASR pilot tests at the Kissel and Gardner Wells (Golder 2001 and 2014b, respectively), which also showed increases in HAAS and TTHM concentrations during the initial weeks of storage Yakima ASR Program 16 WY 2015 Annual Report By June 3rd, both HAAS and TTHM concentrations dropped to very low levels. It should be noted that the Gardner well was pumped between April 30 and June 3. Approximately 340 af of water was pumped during this period (relative to a total of 125 af of water recharged prior to April 3 0) 4.3 Recovered Water Quality Water quality monitoring in recovered water is required at the beginning of recovery, and after recovery of 50% and 100% of the recharged quantity has been withdrawn. Samples must be collected at each well used for recovery of stored groundwater No recovery of stored groundwater occurred in WY 2015 Accordingly, no samples of recovered water were collected However, the results of sampling of stored water (Section 4.2) are indicative of the quality of water withdrawn from the Gardner Well in WY 2015 during regular municipal operations. 5.0 Summary and Expectations for WY 2016 The City of Yakima' s WY 2015 Recharge Cycle and subsequent storage was conducted under the 2015 Permit issued by Ecology in February 2015 5.1 Recharge Volume A total of approximately 41 million gallons (125 1 acre-feet) was recharged to the aquifer via the Gardner Well during two periods of recharge in March and April 2015 No other wells were used for recharge. Recharge volumes were less than the anticipated volumes for WY 2015 because: • The 2015 Permit was not issued until February 24, 2015, so no recharge could occur from October 2014 through February 2015, • The Kissel Well was not operable due to pump removal for replacement; • Elevated turbidity in Naches River source water led to reduced capacity of the NRWTP and suspension of recharge on March 15 Recharge resumed on March 25 after turbidity levels subsided • Drought conditions resulted in curtailment of some of the City's surface water rights used for diversion of recharge source water; remaining surface water rights were needed for municipal supply after April 20, 2015. The Gardner and Ahtanum wells showed clear response to recharge during WY 2015. Water levels in the Kissel, Kiwanis, and Airport wells increased throughout the recharge period. However, it is unclear how much of this increase may be attributable to recharge vs regional conditions, such as antecedent water level trends (e g recovery from pumping) and interference pumping from nearby wells. 5.2 Storage and Recovery No stored water was recovered under the ASR program during WY 2015. Stored water is reserved for future recovery as provided in the 2015 Permit Of the 125 1 af recharged in WY Yakima ASR Program 17 WY 2015 Annual Report 2015, 100.1 af would be available for recovery in WY 2016 (80% of WY 2015 recharge volume). 5.3 Recharge Water Quality Recharge water (source water) at the Gardner Well slightly exceeded the 2015 Permit compliance criterion for total HAAs (HAAS) on all sampling events Compliance limits in the 2015 Permit for HAAS are 30 ug/L (which represents 50% of the drinking water regulatory maximum of 60 ug/L). The measured concentrations of HAAs were still well below the drinking water regulatory limit of 60 ug/L at all times The 2015 Permit limit for TTHMs was also exceeded during the first sampling event on March 11, but all source water was still below the regulatory limit of 80 ug/L at all times. 5.4 Storage Water Quality Stored water was sampled at 11 days and 44 days after the end of WY 2015 recharge. HAAS and TTHM concentrations were below regulatory drinking water limits at all times The June 3 storage sample, which represents an aquifer residence time of 44 days, had very low levels of Both HAAS and TTHM. It should be noted that approximately 340 af of water was pumped from the Gardner Well between April 30 and June 3 (relative to a total of 125.1 af of water recharged prior to April 30) 5.5 WY 2016 Expectations The ASR program for WY 2016 will include refinements and adjustments based on the results of the WY 2015 recharge. The City will continue to communicate closely with Ecology on the operation of the ASR system during WY 2016. The pressure transducer in the Gardner Well has been replaced to improve reliability of water level measurements during recharge. No recharge operations are expected at the Kissel Well for WY 2016 The City may initiate development of a dedicated ASR well, but this is not expected to be completed until WY 2018, after the final ASR permit has been issued Therefore, no withdrawal of recharged/stored water is expected in WY 2016. As with WY 2015, some withdrawal from City wells (including the Gardner Well) is expected to occur under existing water rights to meet municipal demand The target recharge volume for WY 2016 is estimated to be 1,000 af. The ability to achieve this recharge volume will depend on • Initiation of Recharge: It is hoped that recharge can begin earlier in the water year (i e before March 2016) • Turbidity at Source Similar to WY 2015, if high turbidity is observed at the water treatment plant, recharge will be curtailed. • Drought Curtailment Similar to 2015, it is possible that WY 2016 will be another drought year and the City may have limited ability to divert source water starting in late spring 2016 Yakima ASR Program 18 WY 2015 Annual Report The City is currently drafting a revised Water System Plan (WSP) that includes a detailed Operations and Maintenance (OM) manual for the entire water system, including the ASR program The OM manual will include operational protocols for the entire system, such as monitoring and controlling DBP precursors (e g , organic matter) and chlorine residuals It will also include protocols specific to ASR, such as water quality criteria for initiating and terminating recharge, and maintenance requirements for the monitoring network (e.g., guidance on water quality sampling and water level monitoring) To address the water quality issues experienced in WY 2015, the City is preparing a set of Standard Operating Procedures (SOPs) for the ASR program The SOPs will address procedures such as confirmation testing of source water before recharge begins, ongoing review of sampling data during recharge; action levels for increasing monitoring frequency or terminating recharge; contingency plans; and coordination with Ecology. The City will provide the SOPs to Ecology for its review before beginning recharge in WY 2016 The final SOPs will be incorporated into the OM and WSP City Water System Operators will receive training on the ASR system, the requirements of the 2015 Permit and the SOPs before recharge begins in WY 2016 In addition, the City may undertake periodic monitoring of the City of Union Gap's Cahalan Well (Union Gap Well 5; Table 3-1, Figure 3-1) to ensure stored water quality remains within Drinking Water standards for downgradient users The City also requests the opportunity to consult with Ecology to develop a more readily implementable schedule for sampling source water during recharge, such as sampling after recharging every 1,000 of of water, or sampling every two months Yakima ASR Program 19 WY 2015 Annual Report 6.0 References Golder 2000 Golder Associates Inc.

This Temporary Permit authorizes the storage, recovery and beneficial use of water for municipal supply, subject to the provisions included below. On April 12, 2002, the City of Yakima (City) filed Application No. R4-34552 with the Washington State Department of Ecology (Ecology) for a new reservoir permit. The source of water is a diversion from the Naches River under Acquavella Court Claim Nos. 02110, (A) 02826, (A) 03014, (A) 03015, and (A) 05474, Superseding Certificate No. S4-01141 C(A),Superseding Permit No. S4-01141 P(B), and Certificate No. G4-00990ALS. The existing diversion structure from the Naches River is located within the SW 'A, Section 13, Township 14N, Range 17E.W.M., Yakima County, Washington. The proposed reservoir is an aquifer in the Upper Ellensburg Formation. The proposed project entails diversion of source water, treatment at the City's water treatment plant, conveyance through the distribution system, injection into the aquifer system, and withdrawal of the stored water by wells at a later date for municipal uses. The proposed points of injection are the City's Gardner well located approximately 1400 feet south and 1250 feet west of the northeast corner of Section 36, T. 13N., R. 18E.W.M. and the City's Kissel Well located approximately 300 feet east and 100 feet south of the north-west corner of Section 35, Township 13 North, Range 18E.W.M. The associated Yakima County Tax Parcel Nos. are 181336-14033 and 181335-22014. The Gardner Well is located in the northwest corner of Gardner Park in the south end of the City. The Kissel Well is located in the northwest corner of Kissel Park, in the south end of the City. The proposed points of withdrawal are the City's existing domestic groundwater wells (Gardner, Kissel, Airport and Kiwanis). This Temporary Permit is associated with the Pilot Phase of the City's Aquifer Storage and Recovery (ASR) project. Work to be performed under this authorization is described in the City of Yakima Technical Memorandum, ASR Application R4-34522 Package, prepared by Golder Associates, Inc., dated December, 2014 (ASR Technical Memorandum), as amended below. This project is part of the groundwater storage element of the Yakima Basin Integrated Water Resource Management Plan. Potential benefits of this project include: • Surface water diverted in winter months can be used to restore the aquifer water balance and build up a reservoir over time, to be drawn upon as needed. • Capturing winter streamflow for use in summer will help off -set anticipated hydrologic shifts in the tinning of runoff resulting from climate change. • Over time, potentially large volumes of water could be stored underground in the Yakima Valley for far less cost compared to an equivalent surface water storage facility. • Artificially recharged groundwater is likely to increase Yakima River baseflow year round. o - City of Yakima February 24, 2015 Page 2 of 4 • Yakima River benefits from increased baseflow are likely to accrue above the Parker gage, potentially increasing Total Water Supply Available. • The City may reduce their diversion of surface water during low flow times and draw upon groundwater stored in the aquifers, allowing more water to pass their diversion on the Naches River during that time. • Stored groundwater could be pumped and used to augment river flow. • Additional recharge/recovery wells can be installed to increase the capacity of the system and spread capital costs over time. • lnterties with neighboring water systems may be included in an expanded regional groundwater recharge program. • Recharged water and associated water seepage to the river may be used to offset or mitigate other water uses. A significant amount of information has been collected for this project that the City and Ecology are using to evaluate project operation and environmental impacts. This information will be used to prepare a reservoir permit that meets the requirements of Chapter 173-157 WAC, as proposed in Reservoir Permit Application No. R4-34552. This Temporary Permit will provide additional information and allows the City to recharge, store and beneficially use stored groundwater using existing wells as the point of withdrawal while Ecology is reviewing the application. This TEMPORARY PERMIT is subject to the following conditions: 1. This Temporary Permit becomes effective immediately and will remain in effect until January 1, 2017, unless sooner revoked, revised, or extended by the Department of Ecology. 2. All expenses, risks, and liabilities incurred during operation under this temporary permit shall be borne by the applicant. If senior water right holders, including wells exempt from permitting under RCW 90.44.050, are adversely affected during any portion of the operations the activity shall be terminated immediately. 3. This Temporary Permit may be revoked if the applicant fails to comply with the terms and conditions of this Temporary Permit. 4. The issuance of this Temporary Permit in no way guarantees a reservoir permit will be issued. 5. Withdrawal of stored groundwater for beneficial use may take place from any of the City's existing municipal wells (Gardner, Kissel, Kiwanis and Airport), at rates and volumes described in the ASR Technical Memorandum. 6. No discharge of water to surface waters of the state is authorized in this Temporary Permit. The City shall monitor the discharge of water on the surface to ensure that all discharge water infiltrates prior to reaching surface water. Water quality field parameters shall be observed during recovery of stored water as described in the ASR Technical Memorandum, as amended below. If any water quality problems are observed during any portion of the ASR operations, water quality samples shall be collected for laboratory analyses and/or the activity shall be terminated immediately. 7. The City shall manage recharge operations and proceed with adequate safeguards in place to prevent the injection of water with DBP concentrations higher than 1/2 the current drinking water limits for DBPs. This includes the requirement that the City continue to follow WA DOH and US EPA guidance and requirements to minimize the formation of disinfection bi-products to the maximum extent reasonable. 8. The anticipated schedule, volume, and rates of recharge, storage, and recovery are as outlined in the ASR Technical Memorandum except as follows: total recharge under this temporary City of Yakima February 24, 2015 Page 3 of 4 authorization will not exceed 4,000 gpm or 3,000 AF per year. 9. Water quality samples shall be collected and analyzed for DBP's in accordance with the following table using methods and procedures as described in the Gardner Well ASR Test Quality Assurance Project Plan, prepared by Golder Associates, dated April 10, 2014. Copies of the Quality Assurance Project Plan can be obtained by contacting Ecology's project coordinator. Source water samples shall be collected as near as possible to each recharge well. Storage groundwater samples shall be collected from each well used for recharge. Recovery groundwater samples shall be collected from each well used to recover stored groundwater. Percentages represent recharge volumes within an annual recharge cycle. Phase Percent of Recharge Volume Media Recharge 0% Source Water 50% Source Water 100% Source Water Storage 1 month after recharge ends Groundwater Recovery 0% Groundwater 50% Groundwater 100% Groundwater 10. All activities shall comply with the procedures as specified in the ASR Draft Technical Memorandum, prepared by Golder Associates, dated December 2014, except as Ecology may approve in writing prior to any material deviation, and the attached Quality Assurance Project Plan, dated April 10, 2014. 11. Deviations from the program outlined in this temporary authorization shall be documented and request for approval shall be submitted in writing to Ecology's project coordinator. 12. The operator of the system under this authorization shall have a copy of this Temporary Permit and be aware of the parameters and provisions and operate accordingly. 13. All water level, flow rate, temperature, pressure, water quality, and other relevant data collected as part of the Temporary Permit shall be provided to Ecology in electronic format (i.e., spreadsheet) with the reporting requirements as described in Section 7.3 in the Draft ASR Technical Memorandum prepared by Golder Associates, dated December 2014. 14. This Temporary Permit shall in no way excuse the permittee from compliance with any applicable federal, state, or local statues, ordinances, or regulations including those administered by other programs of the Department of Ecology. 15. The issuance of this Temporary Permit does not convey a right of access to or other right to use land, which you do not legally possess. Obtainment of such a right is a private matter between the applicant and owner of that land. 16. The water sources and/or transmission facilities may not be located entirely upon the land owned by the applicant. Therefore, the applicant is advised that issuance of a permit by the Department of Ecology for appropriation of waters in question does not convey a right of access to, or other right to use, land which the applicant does not legally possess. 17. Ecology personnel, upon presentation of proper credentials, shall have access at reasonable times, to the records of water use and data collection that are kept to meet the above conditions, and to City of Yakima February 24, 2015 Page 4 of 4 inspect at reasonable times any measuring device used to meet the above conditions, but only to the extent othettivise allowed by law.

For example, in a year in which Reclamation storage control begins on May 15 and runs through October 15, only 1,267 AF of the authorized 2,172 AF would be available. The actual Qa available in any given year varies depending on the dates on which storage control begins and ends. In 2013, as part of the City's settlement of Acquavella claims, the Qa authorized for the City's Old Union water right was reduced from 5,585 AF Appendix C Summary of Groundwater Rights for City of Yakima Production Wells (This page intentionally left blank) Table C-1: Summary of Existing Groundwater Rights for City Production Wells Well Associated Water Right Instantaneous Withdrawal Rate, Qi (gpm) Currently Installed Wells Kissel CG4-00190-A(A)C (Superseding Certificate); CG4-00190-A(B)P (Superseding Permit); CG4-GWC2851-A@2 2,900 Gardner CG4-GWC2851-A@2 3,000 Airport CG4-GWC5318-A 2,800 Kiwanis CG4-GWC 04646-A (G4-*04954CWRIS) 2,300 Total Currently Installed Wells 11,000 Appendix D WY 2015 Water Quality Results (This page intentionally left blank) Table D-1: Summary of DBP Results for WY 2015 Sample Date M/Y 2015) ASR Cycle Well % of Sampled Recharge Volume 11 -Mar Recharge 2 -Apr 20 -Apr Recharge 1 -May 3 -Jun Storage Gardner Halo acetic Acids (HAAs Dichloroacetic Acid Trichloroacetic Acid 2% 19.7 18.7 Total HAAs (HAAS) T rihalomethan Chloroform 38.4 54 Bromo- dichloro- methane 3.9 es Total Trihalo- methanes (TTHMs) 57.9 33% 14 174 31 4 29 6 16 31 2 100% 158 16 1 31 9 31 2 17 32 9 9% 21 3 23 44 3 50 7 25 53 2 274% <1 <1 <1 1.4 <0.5 1.4 1 Represents percent of total volume of recharged water that had been recharged or pumped during production under existing water rights -' not measured Table D-2: Summary of Field Parameters Collected during WY 2015 Sample Date (WY 2015) ASR Cycle % of WY 2015 Recharge Volume' Well Sampled pH (s.u.)

ASR Standard Operating Procedures This page left intentionally blank. ASR OPERATIONS AND MAINTENANCE PROCEDURES FOR GARDNER WELL INTRODUCTION The City of Yakima (City) is qualifying an Aquifer Storage and Recharge (ASR) program to enhance and/or supplement municipal drinking water supply during drought and other surface water curtailment. The source water for recharge is treated drinking water from the city's Naches River Water Treatment Plant (WTP) and supplied to the recharge well(s) through the distribution main network. This document will serve as a guide for City personnel to operate and manage this process. References will be made to Department of Ecology 2015-2017 permit (Permit), and Golder Associates Technical Memorandum: City of Yakima ASR Application R4- 34552 Package (Tech Memo). It is understood this document fulfills the City's obligation as cited in Sec. 5.4 of City of Yakima Annual Report on ASR Operations, WY2015, and to provide guidance for WY (water year) 2016 and beyond. This document will be amended and refined as more information and requirements become available, and will be incorporated into the WTP Operations and Maintenance Manual. INITIATION OF RECHARGE Prior to the beginning of any recharge two things must be known: the water quality of distribution supply in terms of DBP's, and how much the City intends to recharge into the aquifer. Informational DBP samples must be collected from the well distribution piping in the pump room and results must be returned before the recharge phase can be started. The ASR sample tap is located just "upstream" from the ASR piping isolation gate valve. Currently, Edge Analytical in Burlington is our accredited lab for these samples. Turnaround times vary between one and three weeks being typical. The sample consists of two 40 ml VOA's for Total Trihalomethanes (TTHM's), and two 125 ml bottles for Haloacetic Acids (HAA5's). Directions for sampling and shipping are provided by Edge with every sample kit. These kits and informational samples are separate and distinct from the compliance monitoring for Stage 2 D/DBPR, but the sampling procedure is the same. DBP sample kits are pre -ordered and are delivered to the WTP. The distribution source water cannot exceed 40 ppb TTHM or 30 ppb HAA5 prior to initiation of recharge. These concentrations represent 50% of the MCL's (Maximum Contaminant Limit) for each parameter. While these concentrations do exceed groundwater limits, an Overriding Public Interest ruling will allow recharge at these values. The volume of intended recharge must be known in order to ensure sampling can occur as close as possible to 50% of the recharge quantity. Three recharge samples are required to comply with the Permit: Initiation, 50%, and Termination. Initiation and termination are self -defined. The 50% sample can be difficult to pinpoint due to operational conditions being unpredictable. For example, the City may intend to recharge 1000 acre-feet (AF) but due to unforeseen circumstances may not be possible. The strategy as it now stands is to sample more often than necessary; either by regular elapsed times or by trying to cluster a group before the intended midway point as defined by volume recharged and conditional forecasting. In this example, if everything went perfectly, there will always be a sample taken at 500 AF. The City intends to work with Ecology to refine this sampling process. 2.1 INSTRUCTION FOR RECHARGE INITIATION If the DBP samples come back below the 40/30 ppb threshold, City staff can begin recharge. The first step is to flush the distribution system. Coordinate with Water Distribution to obtain a discharge flow diffuser. Close the street main valve located in the southeast corner of the intersection of Pierce and Cornell (vPC). Closing vPC ensures flush flow from Washington Avenue. Attach a sufficient length of firehose(s) to the fire hydrant located on Cornell to the west of the wellhouse to reach the sanitary pit on the north side of the wellhouse. Attach a flow diffuser to the end of the firehose(s) and open the hydrant to flush the distribution main for one hour. Notify the wastewater treatment plant (WWTP), 575-6077, that there will be ^'30,000 gallon discharge of drinking water at this location. When flush is complete slowly close the hydrant and roll hose(s) to store in wellhouse. Leave vPC closed. Enter the stored ASR flow volume from the ASR flowmeter on the ASR logsheet. We may now begin the actual recharge. This is accomplished by opening the two recharge piping isolation gate valves. Once the gates are open flow is controlled with the Rotork actuator / butterfly valve. This is an electric motor actuated valve with remote and local controls. At this time local control is mandated due to the actuation speed of the valve and the uncertainty of the remote control operation and response. Use the local control to achieve the desired flow rate. The flow is totalized in the SCADA system so daily visits to the wellhouse are not required. 3 MONITORING AND MAINTENANCE DURING RECHARGE In the event of a DBP sample being above 40/30 ppb while in recharge, the process must stop and measures taken to get the distribution system supply near the recharge well back below the threshold. Only after a sample comes back below 40/30 ppb can recharge resume. The samples taken to determine 40/30 ppb in order to resume a recharge are not considered another initiation sample or other permit -required sample, although the procedure is the same: ASR tap, two week lag time, etc. During recharge the City staff will monitor the SCADA system for unusual accumulation of backpressure head (bph) in the well which would indicate clogging. For example, the recharge flow is 1000 gpm, the bph is 500', and has been steady for several days. City staff observe a sudden and sustained jump to 550' with either no change or a loss of recharge flow. Staff are then advised to stop recharge and backflush. A slow and steady rise of bph accompanied by a loss in recharge flow may or may not be interpreted as a blockage in need of backflush. A sudden rise in bph as a result of a recharge flow increase is not an indicator of blockage. A significant closing of the Rotork valve that does not result in a recharge flow decrease or decrease in bph may be interpreted as a blockage in need of backflush. 3.1 BACKFLUSH PROCEDURE Stop the flow of recharge by closing the upstream gate valve. The reason we use the upstream gate valve first is to ensure a water hammer does not occur. Then close the Rotork valve. Then close the downstream gate valve. Open vPC. Start the well motor as per standard well start-up procedure and run in production for length of time and flow rate determined by City staff, e.g. 1500 gpm for 4 hours. There may or may not be any sign that blockage is cleared. Only by re- starting recharge will it be known if backflush was successful. A successful backflush is indicated by a lower bph at previous recharge flow. To re -start the recharge after a backflush once again close vPC and repeat section 2.1. There is no sampling requirement for this backflush procedure. Water produced from a backflush is not deducted from the volume previously recharged but is considered production flow. r 1 ERMINATING RECHARGE Recharge termination consists of sample acquisition from the ASR tap, closing the upstream gate valve, closing the Rotork valve, closing the downstream gate valve, and opening vPC. Recharge termination can be the result of recharge volume limit, operational necessity, or maintenance necessity. Once recharge termination is confirmed there is ideally a minimum 30 day storage period to be observed. This allows the water time to react chemically in the ground. This storage period may be cut short due to operational necessity. RECOVERY After the storage phase has been determined sufficient, recovery may begin. This is simply defined as turning the well on as per standard start-up procedure. Within one hour of start-up an informational DBP sample must be collected from the Recovery tap. This sample tap is located on the well discharge piping in the pump room just "upstream" from the Cl2 injection. There are three samples to collect: 0%, 50% and 100%. These values correlate to the volume of water supplied during recharge. As in the previous example of 1000 AF, the 50% sample will be when 500 AF are recovered. 0% and 100% are self -defined. i SAMPLE SCHEDULE TABLE This is the sampling schedule from the Permit. The City intends to work with Ecology to refine this schedule as operational experience reveals efficiencies.

Suggested Recoverable Quantity Schedule and Model Results The City may use a simplified spreadsheet to account for water recharged and recovered, and will use SCADA to provide the required information for flow, levels, and C12. The datalogger at AYP monitoring well must be periodically accessed for downloads and battery checks. City staff will use a laptop with the Aqua4Plus application and USB adapter to interact with the datalogger. When the batteries in the datalogger discharge to 2.0v it is advised to change them. To accomplish this simply pull up the datalogger and unscrew the rear end -cap to access the batteries. After replacement and re -assembly, lower the datalogger back down the well casing. The depth is set by rigging on the cable and care will be exercised so that the depth is set to the previous elevation. Because this is a monitoring well there is no disinfection requirement following surface exposure to the datalogger or cable, but staff will attempt to keep debris from entering the well. The Aqua4Plus application is the used to reprogram the datalogger for sampling events every 1 hour for a more than sufficient time to allow uninterrupted operation between logons, currently every 3 months.

Section 2 — City of Yakima Water / Irrigation System Information System ID 991509 System name and address City of Yakima Water / Irrigation Division 2301 Fruitvale Blvd Yakima, WA 98902 Directions to Water / Irrigation Offices From Hwy 12, take the N. 40th Ave exit, turn left on Fruitvale Blvd for approx. 2 miles. City of Yakima Public Works complex will be on North side of Fruitvale Blvd Basic description of system facilities PRIMARY SUPPLY The primary water supply is from the Naches River, and to a lesser degree, at the Wapatox diversion dam (from the beginning of April through the end of October) and intake structure West of Naches on Hwy 12. The water from the Wapatox Canal is now supplied to the old City of Yakima intake structure from the Wapatox flush ditch and not from the old PP&L tailrace Along with the tailings from the Wapatox flush ditch, a small amount of Naches Selah irrigation canal water supplies the flush ditch as well. The influent water for the Naches River Water treatment Plant is from direct diversion of raw water through the head gates of the City of Yakima's raw water intake structure. When the head gates are open to achieve the desired flow directly from the Naches River the Obermeyer inflatable weir at the lower intake structure and fish bar shall be in place. During periods of extremely low flows it may be necessary to dig a channel from the main portion of the river directly to the head gate structure in order to direct the flow into the intake structure. This has been accomplished in the past by using heavy equipment in the river and is done with a hydraulic permit from Washington Department of Fish & Wildlife and a shoreline permit exemption from Yakima County Through this structure the main source of supply is diverted to the City's Naches River Water Treatment Plant which provides treatment by coagulation, filtration and disinfection This water is delivered by gravity flow through a 48" transmission main to the distribution system. Note: The City of Yakima's primary and secondary source descriptions can be found in Appendix B. Emergency Op Guidelines Emergency Op Guidelines SECONDARY SUPPLY The City of Yakima's four wells are capable of pumping directly into the distribution system Disinfection is provided for at each site The four wells pump directly into the low pressure zone of the distribution system. These groundwater supplies are utilized as a seasonal water source and are maintained in a standby status. The four wells are as follow Kissel Well at 32hd Ave and Mead Ave, Airport Well on Washington Ave across from Perry Tech, Gardner Well at Gardner Park on Pierce and Cornell, Kiwanis Well at Kiwanis Park on Maple St STORAGE AND DISTRIBUTION The distribution pipelines are 4 to 24 inches in diameter. The pipe materials are mainly cast iron, with ductile iron being used since the early 1970's There are several steel pipelines and many unlined cast iron pipelines remaining in the system There is approx one mile of Asbestos Cement Pipe on Englewood Ave. The City's existing storage capacity is 32 million gallons (MG) distributed among five reservoirs within the three pressure zones. Each pressure zone has an established hydraulic elevation This elevation is maintained by the distribution reservoirs located in each of the pressure zones. Note: The reservoirs are shown on the hydraulic profile in Appendix C. The table indicates the volume of storage, zone served, type of material, and the overflow and floor elevation of the five reservoirs in the distribution system. PUMP STATIONS The City of Yakima operates four booster pump stations. Three of the booster pump stations (40th Ave. pump station, Stone Church pump station, and 3rd level pump station) provide water to the middle and high zones, as shown in the hydraulic profile The fourth pump station is at Gleed and supplies water to approximately 25 customers in the Gleed area Note: The pump stations are listed in Appendix D, indicating the location, supply location, zone that is served, number of pumps in each station, pump capacity, and other characteristics. INTERTIES The Nob Hill Water Association and the City of Yakima have two emergency interties between their respective distribution systems. 1 Intertie is located at the intersection of N 56th Avenue and Lincoln Avenue This connection is between the City of Yakima's high pressure zone and Nob Hill Water Association's middle pressure zone The City of Yakima High Zone System pressure exceeds the Nob Hill Water System pressure by approximately 7 psi. 2. Intertie is located at S. 32nd Avenue and Ahtanum Road. This connection is between the City of Yakima's low pressure zone and Nob Hill Water Association's low pressure zone through a two way pressure reducing valve.

There are a variety of reasons including • Natural disasters • Accidents • Deliberate acts of vandalism or terrorism • System neglect or deferred maintenance Type of event Probability or risk (High -Med -Low) Comments Flood High During spring runoff there are several City of Yakima water facilities that have the potential to be damaged and water quality compromised at flood stage water levels, as well as the possibility of flooding within buildings due to process / equipment malfunction. Earthquake Med The Pacific Northwest has the potential for earthquake activity that could cause damage to distribution system, WTP facilities, and irrigation systems Fire Med The Yakima Valley is susceptible to both wild fires as well as structure fires that may require action on the part of the City of Yakima Water/Irrigation Division to assist emergency personnel in redirecting flow of water for higher pressures for fire fighting. High winds Med System is vulnerable to high wind events Power ma be disrupted, telemetry disruption, water facilities can be damaged due to high winds Ice and Snow Storms Med Excessive ice and snow can damage water facilities, freeze pipes (burst mains), freeze water meters and make transportation during emergency events difficult. Emergency Op Guidelines Drought Med Need to plan for decrease in available water for late spring, summer and early fall during a drought year Construction accident Low Contractors occasionally damage buried water lines while excavating Terrorism Low Need to be trained on suspicious activity and report to proper authorities Chemical spill Low City of Yakima has a wellhead protection plan Section 5 — Severity of Emergencies Level I Emergency Description: The City of Yakima Water/Irrigation Division shall consider the following level I emergencies • Distribution line breaks • Irrigation line breaks • Short power outages • Minor mechanical problems at WTP, Wells, Booster Pump Stations • A minor act of vandalism • Other minor situations that would not likely risk public health The system has specific response activities identified for these types of emergencies, including proper sampling, disinfection, and pressure testing activities System personnel are advised and are directed to work on the problem and are usually capable of resolving the problem within 24 hours If it is determined that the problem will take longer than 24 hours to resolve and storage is likely to be drawn down below a safe operating level, the situation will be elevated to level II Level II Emergency Description: The City of Yakima Water / Irrigation Division shall consider the following level II emergencies • Disruption in supply such as a transmission main line break, pump failure with a potential for backflow, and loss of pressure • Storage levels are not adequate to handle disruption in supply • An initial positive coliform or E coli sample • An initial primary contaminant sample • A disruption in chlorine/chemical feed from the groundwater sources • Drought, with noticeable and continuing decline of water level available from surface and groundwater sources Emergency Op Guidelines Level III Emeroencv Description: The City of Yakima Water/Irrigation Division shall consider the following level III emergencies • A verified acute confirmed coliform MCL or E coli/fecal positive sample requiring immediate consideration of a health advisory notice to customers • A confirmed sample of another primary contaminant requiring immediate consideration of a health advisory notice to customers • A loss or complete malfunction of the water treatment facilities for the surface water source, including, but not limited to, chlorination • A major line break or other system failure resulting in a water shortage, requiring system shutdown and assistance from Nob Hill water Association • If the first level system has a main break that may cause low pressure at hospitals and/or assisted living facilities, it is necessary to turn on Stone Church pump station as soon as possible • An act of vandalism or terrorist threat such as intrusion or damage to a primary facility • An immediate threat to public health of City of Yakima customers and an advisory is required • Severe drought significantly affecting surface water or groundwater sources. NOTE: If the City of Yakima Water/Irrigation Division experiences significant mechanical or contamination problems where disruption in supply is inevitable and issuance of a health advisory is needed to protect public health Major emergencies should be reported to DOH as soon as possible to determine the best available means to protect customers' health System personnel are directed to the situation, and outside entities are notified to aid in the response. Major emergencies may require more than 72 hours to resolve. Level IV Emergency Description: The City of Yakima Water/Irrigation Division shall consider the following level III emergencies: • Earthquake that shuts down the system or impacts sources, lines, pump stations, etc • Act of terrorism possibly contaminating the water system with biological or chemical agents • Flood that infiltrates system facilities (or is caused from mechanical malfunction within facilities), sources, transmission mains, or causes loss of system capabilities within the distribution system • Chemical spill within 2000 feet of the system's sources • Storm that significantly damages power grid and system facilities • Mudslide or other earth shift that may cause failure of transmission or loss of water in surface or groundwater sources Note: If the City of Yakima Water/Irrigation Division experiences major damage or contamination from a natural disaster, an accident, or an act of terrorism. These incidents shall require immediate notification of local law enforcement, DOH, local emergency management services, local media, and City of Yakima customers An immediate declaration of a water supply emergency is critical to protect public health. These events often take several days or weeks to resolve before the system returns to normal operation Emergency Op Guidelines Section 6 — Emergency Notification Notification Procedures for Level I and Level II Emergencies Who is Responsible: The City of Yakima Water/Irrigation individual supervisors will be responsible for assignment of all emergency duties in regard to Level I and Level II emergencies. These supervisors are responsible for keeping the Water/Irrigation Division Manager informed of the progress of the activities during these emergencies. If the supervisors are not available during these emergencies, crew leaders and plant operators will be responsible for these emergency duties and keeping the Division Manager updated on all activities. Water • Each Water/Irrigation supervisor (or acting representative) will be responsible Emergency for level I or level 11 emergencies, making contact with essential personnel or essential entities, such as Procedures for Level I and 1 City of Yakima Water/Irrigation Manager Level II 2 Essential Water/Irrigation personnel to alleviate water emergencies Emergencies: 3 Any contractor (construction, electrical, pump / motor repair or sales, etc.) that may be needed to alleviate water emergencies. Must follow prevailing wage and insurance guidelines. 4. Wastewater collections and/or stormwater management in the event of any localized flooding due to distribution or irrigation main breaks or chemical spills that may effect stormwater collection or wastewater collection • In the event of a Level 1 or Level 11 emergency, the responsible supervisor (or acting representative) will be required to keep the Division Manager informed of any problems that may require these emergencies to be classified as a higher level of emergency Notification Procedures for Level III, and Level IV Emergencies Who is Responsible: The City of Yakima Water/Irrigation Manager shall be responsible for notifying the city public information officer and assigning public notification duties to desired personnel based on the severity of the emergency. If the Water/Irrigation Manager is not available, the assignment responsibility will go to the City of Yakima Director of Utilities and Engineering or the director's designee. Emergency Op Guidelines Water Emergency Procedures for Level III and Level IV Emergencies: • Water/Irrigation Manager confers with key staff to verify problems • Water/Irrigation Manager organizes staff and public information officer to develop the message to be delivered to the customers (Dependent upon the severity of the water emergency) • Water/Irrigation Manager shall assign personnel to consult with state DOH regarding the problem • Water/Irrigation Manager, with assistance from the public information officer, prepares door hangers, signs and electronic media message • Water system operators continue to investigate problem and make repairs as necessary • Water/Irrigation management team will determine if there is any need for notification of wastewater collections or stormwater management due to localized flooding from distribution line breaks or chemical spills • The water emergency notification will be distributed by 1 Field staff placing "water emergency notices" on doors and along travel routes 2 Staff will place signs on main travel routes into the community 3. Water/Irrigation Manager contacts public information officer and requests issuance of the water emergency notice and any further public education notices for emergency 4. Administrative support personnel will provide a pre -scripted message to phone callers and log each phone call • Water system operators regularly update the Water/Irrigation Manager on water emergency and the progress that is being made • Once the water emergency is resolved, re -notify customers As a Level III or Level IV emergency is resolved an after action meeting will be conducted to determine if anything could have been done better or to determine if any Public Assistance from the State of Washington or FEMA can be applied for NOTE: It is vitally important for all activities, financial, physical work, phone logs, operational logs, and contact information, be documented for FEMA Public Assistance. FEMA forms can be found at the following website: http://www.fema.gov/forms-0 or at www.wawarn.org Section 7 — Water Quality Sampling Many different types of emergencies can jeopardize the quality of water and potentially water customers. Because the most important goal for any water system is to protect human health, the system must know how to act quickly and make decisions on whether to issue a health advisory. Sampling and obtaining results from a lab takes time and this fact should be taken into consideration when considering a course of action during any emergency If there is reason to believe that the water has been contaminated, the Water/Irrigation Manager (or an acting representative) should consult with DOH and consider issuing a health advisory as soon as possible — often before conducting water quality sampling Contamination of drinking water, whether intentional or unintentional, comes in many forms, which are classified in four general categories • Inorganics such as metals or cyanide -- 10 -- Emergency Op Guidelines • Organics such as pesticides or volatile solvents • Radionuclides • Pathogenic microorganisms If it suspected that someone intentionally sabotaged the system or contaminated the water, this should be considered a crime scene Immediate contact with local law enforcement and DOH Division of Drinking Water regional office will be necessary, and it is vitally important that the potential contaminated area not be disturbed in order to protect any potential evidence.

How we communicate with employees, customers, and the media can affect the outcome of the emergency situation It is vitally important that an effective communication plan be developed and adhered to by all personnel involved in any emergency response. A well developed relationship with outside entities can prove to be valuable in an emergency situation In the event of an emergency it may be beneficial for the City of Yakima to look to DOH, DOE, Washington State Dept. of Fish & Wildlife, or the Bureau of Reclamation for assistance in communicating with the public in regard to their individual areas of expertise. The City of Yakima will look to the Public Information Officer or the Emergency management Analyst for assistance with communications with local or national media. Communication Tips Do: • Be prepared. • Designate a spokesperson. • Provide complete, accurate, and timely information • Tell the truth • Express empathy • Acknowledge uncertainty and offer to get back with more information later • Document your communications Do not: -- 20 -- Emergency Op Guidelines • Speculate on the cause or outcome of an incident • Blame or debate • Minimize or brush off concerns of customers • Treat inquiries from interested parties as an annoying distraction from the real business of emergency response. Designate a spokesperson and alternates Water/Irrigation Spokesperson Water/Irrigation Alternate 1 Water/Irrigation Alternate 2 Dave Brown, Manager Randy Beehler, City of Yakima Public Information Officer Emilio Lopez, Supervisor Jeff Bond, Supervisor Rich Sanislo, Supervisor Mike Shane, Engineer Key messages • We are taking this incident seriously and doing everything we can to resolve it. • Our primary concern is protecting public health • Another important concern is keeping the system operational and preventing damage • What we know right now is • The information we have is incomplete We will keep you informed as soon as we know more. • We have contacted state and local officials to help us respond effectively. • If you think you may be ill or need medical advice, contact a physician • We are sampling the water and doing tests to determine whether there is contamination Health advisories During events when water quality and human health are in question, it may be necessary to issue a health advisory that gives advice or recommendations to water system customers on how to protect their health when drinking water is considered unsafe or potentially compromised. These advisories are issued when the health risks to the consumers are sufficient, in the estimation of the water system or state or local health officials, to warrant such advice. Health advisories usually take the form of a drinking water warning or boil water advisory. Communication during these times is critical. Health advisories should always be well thought out and provide very clear messages. -- 21 -- Emergency Op Guidelines The DOH has put together a number of tools, including fact sheets, brochures, forms, and templates to help prepare for a health advisory These are on the Web at http://www.doh.wa.qov/CommunityandEnvironment/DrinkiniWater.aspx Section 9 — Staff Instructions / Contingency Plans for Various Facilities and Emergencies The following water system facilities and supplies have been analyzed for vulnerability situations and contingency plans formed including general and specific instructions on how to handle each problem identified. 1. Supply 2 Naches River Raw Water Intake 3 Transmission Mains 4. Water Treatment Plant Levee 5. Naches River Water Treatment Plant 6 Distribution System and Storage Reservoirs 7 Booster Pumping Stations 8. PRV Stations 9. Electrical Energy Supply 10 Materials and Supplies 11 Communications 12. Transportation 13. Fire and Police Request for Assistance CITY OF YAKIMA MAJOR FACILITIES -- SUPPLY PRIMARY SUPPLY The primary water supply is from the tailrace of the Bureau of Reclamations Wapatox Canal which is supplied from the Naches River at the Wapatox diversion dam (from the beginning of April through the end of October) and intake structure West of Naches on Hwy 12 -- 22 -- Emergency Op Guidelines At times when the Wapatox Canal is out of service (from the end of October through the beginning of April), direct diversions of raw water are available through the head gates of the City of Yakima's raw water intake structure When the head gates are open to achieve the desired flow directly from the Naches River, at the lower intake structure the Obermeyer weir fish bar shall be in place During periods of extremely low flows it may be necessary to erect a coffer dam to direct the flow into the intake structure. This has been accomplished in the past by using heavy equipment in the river to push up rubble from the river bottom to build a coffer dam. A hydraulic permit is necessary prior to placing equipment into the river Through this structure the main source of supply is diverted to the City's Naches River Water Treatment Plant which provides treatment through coagulation, some settling, filtration and disinfection of this supply This water is delivered by gravity flow through a 48" transmission main to the low pressure zone distribution system Note: The City of Yakima's primary and secondary source descriptions can be found in Appendix B. SECONDARY SUPPLY The City of Yakima's four wells are capable of pumping directly into the distribution system Disinfection is provided for at each site. The four wells pump directly into the low pressure zone of the distribution system. These groundwater supplies are utilized as a seasonal water source and are maintained in a standby status INTERTIES The Nob Hill Water Association and the City of Yakima havetwo emergency interties between their respective distribution systems. • This intertie is located at the intersection of 56th Avenue and Lincoln Avenue. This connection is between the City of Yakima's high pressure zone and Nob Hill Water Association's middle pressure zone The City of Yakima High Zone System pressure exceeds the Nob Hill Water System pressure by approximately 7 psi. • This intertie is located at S 32nd Avenue and Ahtanum Road This connection is between the City of Yakima's low pressure zone and Nob Hill Water Association's low pressure zone through a two way pressure reducing valve. Flow is limited to 2,500 gpm in both directions. OPERATING MODES AND ALTERNATIVES The function of the water system's supply is to provide a potable water supply for the City of Yakima. This supply is additionally utilized for fire suppression, sanitation and public health, industry, irrigation and recreation Should the water system's supply cease to be available, the following alternatives may be utilized to augment or replace the water system's supply. • Activation of the City of Yakima's wells. Failure of the water system's main supply to be available may require rationing or restriction of use of the remaining available water supplies The City of Yakima's groundwater sources are capable of meeting the system's average day demand during the fall, winter and spring Restrictions of water use may y be necessary during periods of the year when average day demand increases in the summer. • Activation of the interties with the Nob Hill Water Association. Utilization of the interties with the Nob Hill Water System as a sole source of supply would require rationing. This is because the amount of water available from Nob Hill's water system is limited; especially during the peak use summer months. In addition, the hydraulic capability of the piping making the interties is not of sufficient size to allow flows large enough to meet the City's needs • Hauling of potable water from other safe sources. Hauling of water would only be implemented in extreme emergency when complete loss of the primary, secondary, and intertie source of supplies has occurred. Water hauling has typically been performed by 23 Emergency Op Guidelines LTI of Sunnyside, WA to the Gleed Pump Station to supply water to the unincorporated area of Gleed, however they could provide other water stations through the city STAFF INSTRUCTIONS FOR SUPPLY LOSS POSSIBLE CAUSES: • • Extended periods of drought resulting in loss of river flow. • USBR proration of water storage rights. • Contamination of source water upstream of the WTP due to fuel Naches Wastewater Treatment Plant contamination, etc • Failure of 54 inch transmission main transporting water from the the Water Treatment Plant. • Spring runoff resulting in flooding and increased turbidities exceeding the process capabilities of the Water Treatment Plant. Failure of 48 inch transmission main transporting water from the Plant to the City's water distribution system. ALTERNATIVE 1: Activation of the City wells. spill, car accident, Intake Structure to Water Treatment PROCEDURE: 1. Shutdown the Water Treatment Plant or reduce flows as required. 2. Determine an estimate of the length of time the main source of supply will be unavailable or reduced 3. If it is determined that the water in the storage reservoirs will be inadequate to meet the needs then initiate procedures to activate the wells in the following order Gardner Park, Kissel Park,. Airport, Kiwanis 4 If The 48" transmission main is compromised and water cannot be supplied to Gleed, contact LTI (Sunnyside) to initiate water to the Gleed pump station. The pump station is already set up for temporary supply through the use of LTI's trucks Note: The spare piping for hooking up to the LTI trucks is on the 3rd floor of the WTP. Note: If a valve can be shut to isolate Suntides / Gleed from the failed section of the 48" main, it is vital that this valve be shut so that the water treatment plant can continue to supply water to these areas and the wells in Yakima can supply water to the citizens of Yakima. ALTERNATIVE 2: Activation of the interties with the Nob Hill Water Association. PROCEDURE: 1 Contact representatives of the Nob Hill Water Association (telephone 966-0272) and request that the appropriate interties be opened to allow water to enter the distribution system. 2. Meet the Nob Hill Water Association representatives at the intertie locations and slowly open the control valves until pressure in both systems has stabilized -- 24 -- Emergency Op Guidelines 3 Monitor the pressure levels of the City of Yakima's water distribution system in conjunction with the Nob Hill Water Association Accomplish this by installing pressure gauges on respective system hydrants in the near vicinity of the interties. 4 Implement water conservation until the primary or secondary source of supply is available. ALTERNATIVE 3: Hauling of potable water from other safe sources. PROCEDURE: 1. Implement water conservation until a sufficient supply of water is available to the system Notify City of Yakima Department of Emergency Services and Communications & Public Affairs for assistance in this effort. 2 Notify the local Fire Departments that no water is available for firefighting purposes from the hydrants. 3. Contact LTI (Sunnyside) for use of potable water tanker trucks and request assistance in water hauling operation. 4. The potable water trucks can be filled at the water fill station at the public works, yard (located inside the fence in the southwest corner), Gardner Park Well, and at neighboring water purveyor after approval from specific purveyor 5 The LTI trucks shall be hooked up to Gleed pump station with pre plumbed emergency connections (piping is located at the WTP on the 3rd floor) 6 When each truck is connected to the Gleed pump station, a Bac-T sample and a chlorine residual must be taken and dropped off at Cascade Analytical. When each truck is emptied, chlorine residual must be taken and recorded ALTERNATIVE 4: Drought conditions causing reduced flow from river. PROCEDURE: 1 Implement voluntary water conservation measures until a sufficient supply of water is available to the system Notify City of Yakima Communications & Public Affairs Director (Randy Beehler — 901-1142) and Emergency Management Analyst (Charles Erwin — 576-6732) for assistance in this effort Water conservation tips can be found in Appendix D of this manual 2 In the event that mandatory water conservation measures are required due to loss of the ability to meet domestic flow demand, a council resolution declaring a drought for the City of Yakima will be required Once the resolution has been passed by council, the implementation of mandatory water conservation measures would be in effect until a sufficient supply of water is available to the system. Notify City of Yakima Communications & Public Affairs Director (Randy Beehler — 901-1142) and Emergency Management Analyst (Charles Erwin — 576-6732) for assistance in this effort Water conservation tips can be found in Appendix D of this manual 3. Activate emergency wells to supplement flow in order to meet demand -- 25 -- Emergency Op Guidelines 4 Continue to operate the water treatment plant for as long as possible (dependent upon the ability to continue to draw influent flow from the river) 5 Contact neighboring water purveyor to open intertie and supplement flow in order to meet demand Note: This is to be done only if wells and the WTP are not meeting demand at the maximum flows CITY OF YAKIMA MAJOR FACILITIES - INTAKE DESCRIPTION The major features of the Naches River Raw Water Intake Structure are: • Head Gates to the Intake: The head gates are located at the extreme upstream portion of the structure. These gates are operated manually or powered by a portable generator driven Milwaukee drill motor The gates are used to control direct river diversions. Direct river diversions are necessary when an inadequate supply is available from the Wapatox Canal • Wapatox Naches Selah Canal Bypass (flush ditch): The canal bypass (flush ditch) outlet is located so that the flow enters into the old intake structure. The water from this outlet is not an alternate source of supply. • Radial Gates and Operators: There are radial gates that are located at the extreme downstream portion of the intake structure These gates are powered by electric gear drive operators The purpose of these gates is to control the outflow of water from the Wapatox canal bypass (flush ditch) through the intake structure back out to the Naches River • Old Intake Bar Screens: These screens are located across the opening of the overflow weir and the outboard radial gate overflow weir. These screens were installed by the Washington State Department of Fish and Wildlife in the summer of 1984 The screens are cleaned of trash and operated by Water Treatment Plant staff The purpose of the bar screens is to prevent anadromous fish from entering the intake structure and moving up The Bureau of Reclamations flush ditch. This is necessary to prevent fish from being fooled by the natural attraction of the outflow from the intake as being a tributary where they might spawn • Fish Screens: These screens are located inside the intake structure. They provide protection for fish, by screening out of the water supply. These screens are backwashed automatically with an air bust. • Concrete Wall of the Intake Structure: The concrete wall separates the river from the water confined in the structure Water must be confined within the structure to build a head of water above the 54" pipeline so that the water may flow by gravity through this pipeline to the Water Treatment Plant. OPERATING MODES AND ALTERNATIVES The function of the raw water intake is to divert a supply of water to the Naches River Water Treatment Plant. Due to the Wapatox canal not supplying water to the intake structure and the Naches River diverting away from the head gates, it is necessary to supplement flow from the Wapatox flush ditch over the intake stop logs In order to divert the flush ditch flow over the stop logs, WTP staff will install foam boards next to the old intake fish bars. The installation of these foam boards will increase the head in the old intake structure and flow water over the stop logs to supplement flow to the new intake structure. Should the intake structure or fish screen backwash system cease to function, the following alternatives may be utilized to accomplish some or all of the same functions as stated above 1. Manually maintain flow into intake structure by removing debris as needed. 2 Manually move ice and slush through intake channel by raising and lowering Obermeyer Inflatable Weir as needed to maintain adequate flow and head through channel 3. Provide air for screen backwashing from distribution portable air compressors. -- 26 -- Emergency Op Guidelines Failure of the intake structure would reduce or eliminate the water supply available to the Water Treatment Plant Should the system reserves be inadequate to meet system demands before one of the alternatives above can be implemented, then the emergency should be handled as a loss of supply. STAFF INSTRUCTIONS FOR LOSS OF RAW WATER INTAKE POSSIBLE • Washed out by floods CAUSES: • Filled with debris during floods • Filled with ice ALTERNATIVE 1: Manually maintain flow into intake structure by removing debris as needed. PROCEDURE: 1 Shut down the Water Treatment Plant or reduce flows as required 2 Begin manual removal of debris from intake structure if this can be safely accomplished. 3 Determine an estimate of the length of time reduced flows, or plant shut down may be needed. This information is to be used to determine if the situation requires immediate action of starting wells for maintaining adequate reservoir levels and/or contacting Nob Hill Water Assoc for assistance with an intertie 4. After flows have been restored, adjust flow rate or restart the Water Treatment Plant. ALTERNATIVE 2: Manually move ice and slush through intake channel by raising and lowering Obermeyer Inflatable Weir as needed to maintain adequate flow and head through channel. PROCEDURE: 1. It is primarily important for there to be adequate flow through the head gates at the upstream most end of the intake channel Throughout the winter months it IS necessary to maintain adequate head over the fish screens in the intake structure to maintain gravity flow to the water treatment plant. 2 In extreme cold temperatures (20 degrees Farenheit or lower) it is very likely that the intake channel will become filled and blocked with ice / slush ice. It will be necessary for water plant personnel to try to move ice as much as possible by raising and lowering the Obermeyer Inflatable Weir in order to try to maintain the necessary head over the fish screens. 3 If it is deemed impractical to try to fight the ice, then initiate procedures to activate the wells in the following order: Gardner Park, Kissel Park, Airport, Kiwanis 4 After flows have been restored, adjust flow rate or restart the Water Treatment Plant. ALTERNATIVE 3: Provide air for screen backwashing from distribution portable air compressors. PROCEDURE: 1. In the event that there is a mechanical malfunction at the intake structure in regard to any of the air compressors the water plant staff should contact water distribution and acquire the use of a portable air compressor so that flow through the fish screens can be maintained and/or so the Obermeyer Inflatable Weir can be inflated. 2 Once the repairs to compressor in question are complete, return portable compressor to distribution and resume normal operations. CITY OF YAKIMA MAJOR FACILITIES - TRANSMISSION MAINS DESCRIPTION -- 27 -- Emergency Op Guidelines The transmission mains are pre -tensioned concrete cylinder pipe sizes 54 inch, 48 inch, 30 inch 54 inch = 3,500 L.F. 48 inch = 45,200 L F 30 inch = 3,000 L.F. These mains were installed during the period of 1968-1972 Water flows through these pipelines utilize the force of gravity only. No pumps are required to aid the movement of water. The 54 inch transmission main moves water from the Naches River Raw Water Intake Structure to the Naches River Water Treatment Plant. The 48 inch transmission main conveys water from the Naches River Water Treatment Plant to the City of Yakima's domestic water distribution system. At Gleed pump station there is the Gleed CT facility. The CT facility houses two 48" butterfly valves which can be adjusted to maintain pressure in the 48" main from the WTP to the Gleed site. The pressure between Gleed and the WTP, chlorine residual, pH, and temperature are all contributing factors in maintaining an acceptable CT CT is defined as the residual disinfectant concentration, "C" in mg/L, multiplied by the contact time, "T" in minutes The goal is to achieve a calculated available CT value (CTcalc) that is at least as great as the required CT value (CTreq). In other words, CT compliance is achieved if the ratio of CTcalc / CTreq is greater than one The CT compliance ratio must be greater than one for disinfection compliance Note: If the result is less than one, make appropriate changes and notify the Water Treatment Plant Supervisor. The 30 inch transmission main moves water between the equalizing reservoir at 40th Avenue and Englewood and the 48 inch transmission main. OPERATING MODES AND ALTERNATIVES The function of the transmission facilities is to transport large quantities of water from the source to the point of treatment and disinfection (Naches River Water Treatment Plant) and from this point to the City's distribution system. The 48 inch transmission main has outlets installed along its length at intervals of approximately every 1000 feet Connections to this main can be accomplished through the use of an existing outlet or by direct tap. The hydraulic gradient, as it currently exists, is such that the 48 inch pipeline does not become full of water under normal circumstances until somewhere between Eschbach Road and the community of Gleed. The 48 inch pipeline follows Highway SR 12 from the Water Treatment Plant crossing the Naches River to 40th Avenue where it turns south on 40th Avenue to Powerhouse Road. The main turns and runs along Powerhouse Road to Englewood Avenue at the intersection of Powerhouse Road and Englewood Avenue The 30 inch pipeline between the equalizing reservoir at 40th Avenue and Englewood Avenue and the 48 inch pipelines are connected The 48 inch main continues from this junction along Englewood Avenue to the intersection of 16th Avenue and Cherry Avenue where the 48 inch pipeline terminates with several distribution pipelines radiating out from this terminus. Should the transmission facility cease to function between the source and 40th Avenue, this loss will be treated as a loss of supply. It is still possible that water can be supplied to Gleed and Suntides areas by way of either isolation of the 48" main at the river or by hauling water (contracting LTI) Should the break occur between 40th Avenue and 16th Avenue, then the damaged section will need to be isolated until repairs or replacement can be accomplished Should the 48" transmission main be compromised at the Naches River crossing (just below the Nelson bridges), the damaged section of transmission main can be isolated on both sides of the Naches River Once it has been isolated, provisions have been made to install a 24" bypass from the Gleed side of the Naches River, over the train trestle to the Yakima side of the Naches River. STAFF INSTRUCTIONS FROM TRANSMISSION MAIN FAILURE -- 28 -- Emergency Op Guidelines POSSIBLE CAUSES: • Exposure and damage by river flooding or unauthorized excavation. • Failure from earth movement due to earthquake tremors. • Pipeline material failure. ALTERNATIVE 1: Activation of City wells should transmission main failure result in loss of supply. PROCEDURE: 1. Isolate the damaged area from the system by closing the necessary valves. 2. See loss of supply crew instructions for correct procedures to follow to restore water supply 3. Excavate damaged area to determine extent of the damage. 4. Replace or repair the damaged pipe as required. (No repair parts or additional concrete pipe is kept in stock.) Note: If a valve can be shut to isolate Suntides / Gleed from the failed section of the 48" main, it is vital that this valve be shut so that the water treatment plant can continue to supply water to these areas and the wells in Yakima can supply water to the citizens of Yakima. ALTERNATIVE 2: Activation of river bypass at the train trestle (Nelson bridges area). PROCEDURE: 1. Isolate the break on each side of the Naches River. 2. Wells will need to be started to supply water to Yakima throughout this process. 3 The distribution crew will install a 24" bypass over the train trestle as a temporary fix Once this section of bypass is installed, repair or replacement of damaged section of 48" main will need to be completed (No repair parts or additional concrete pipe is kept in stock.) 4 The water distribution crew has installed a permanent flush line hook up in the 48" main about halfway between the intersection of 40th Ave — Fruitvale Blvd and the end of the US 12 entrance ramp that can be connected to the City of Yakima general irrigation reservoir via 5 inch fire hose Contact the City of Yakima Irrigation Supervisor so that the general reservoir can be isolated from its normal supply. 5 When the repair is complete, chlorination and flushing of the main is required Once the line has been flushed and chlorinated for 24 hours, a Bac-T and chlorine residual must be collected and delivered to Cascade Analytical Once the Water staff has received a satisfactory result from Cascade Analytical from the Bac-T sampling, the main can be put back into service and customers notified of normal operations. CITY OF YAKIMA MAJOR FACILITIES - NACHES RIVER WATER TREATMENT PLANT LEVEE DESCRIPTION The City of Yakima WTP levee is approximately 1150 feet long and is located on the east bank of the Naches River in Section 24, Township 14 North, Range 17 East, Willamette Meridian, and Yakima County, Washington. The levee protects the Naches River Water Treatment Plant structures, the WTP waste pond area, as well as the public parking/ fishing access area off of State Highway 12. -- 29 -- Emergency Op Guidelines The City of Yakima WTP staff maintains the levee by periodically pruning the vegetation, placing gravel on the surface, and performing pre- and post -flood inspections. This level of maintenance is consistent with the standards of the Seattle District Corps of Engineers for eligibility in the Rehabilitation Inspection Program It is increasingly important for WTP staff to be diligent in pre and post spring run-off inspections of the levee due to increased river level that may adversely affect the levee. Should there be a high water event that has damaged the WTP levee, please follow Staff instructions listed below NOTE: Should there be any questions that arise in regard to the proper maintenance or operation parameters for the WTP levee, the Army Corps of Engineers Levee Owners Manual for Non -Federal Flood Control Works, can be found in the WTP supervisor's office. More information can be found in Appendix I of this manual. STAFF INSTRUCTIONS FOR WTP LEVEE DAMAGE POSSIBLE CAUSES: • Damage from high water / flood event • Damage from earthquake ALTERNATIVE 1: If it has been determined that there has been levee damage on either the riverward or landward side of the levee due to a high water / flood event, it is crucial to proceed to the following procedures for life and property safety. -- 30 -- Emergency Op Guidelines PROCEDURE: 1. Record level of river at Naches River measuring station. Note: If the Naches River is predicted to be above flood stage and the City of Yakima has mobilized the personnel and equipment available for a flood fight, the levee is in danger of being breached, it will be necessary to contact the Army Corps of Engineers and request "Technical Assistance". At this time the ACE will determine their ability to respond to our levee for a flood fight. ALTERNATIVE proceed to the PROCEDURE: 2 If river levels are predicted to rise and it appears that the levee will be over topped, personnel and equipment should be mobilized to fill and transport sand bags to protect the WTP Main building, Chemical building and Fluoride building. Upon the mobilization of personnel and equipment for a flood fight at the WTP levee, a 10 yard dump truck will need to be dispatched to Central Pre -Mix to obtain sand for sand bags (Central Pre -Mix contact info is on page 17 of this manual Note: One ton super sacks for sand bagging of a breached levee can be obtained at the Water/Irrigation warehouse. Smaller sand bags for use at WTP entry points can be found on the WTP third floor storage. For the filling of sand bags, the filter media hopper at the WTP can be used to dump sand into and fill bags at the bottom of the hopper. 3. It will need to be determined if the WTP needs to be isolated / shut down and secondary sources started due to potential flooding of WTP structures If flooding of WTP structures is possible, sand bagging of WTP structures may be necessary to prevent flooding of pipe gallery, chemical building, and / or fluoride building 4. If the City of Yakima's wells will not be enough to meet the water demand in Yakima, emergency water restrictions may need to be imposed and/or it may be necessary to contact Nob Hill Water Association to open interties. 5 While repairs are being completed on the levee it will be necessary for Water/Irrigation staff to continually assess whether the WTP can be operational, the secondary sources should be operational, emergency restriction on water may need to be continued or if the Nob Hill Water Association interties should be open. 6 It is vitally important for all activities, financial, physical work, phone logs, operational logs, and contact information, be documented for Washington State and / or FEMA Public Assistance 2: If the WTP levee has been compromised due to earthquake it will be crucial to following procedures for life and property safety. 1. In the case of an earthquake that has affected the levee, follow the instructions for a flood and levee damage -- 31 -- Emergency Op Guidelines CITY OF YAKIMA MAJOR FACILITIES - NACHES RIVER WATER TREATMENT PLANT DESCRIPTION The existing Naches River Water Treatment Plant (WTP) has a rated capacity of 25 MGD with a direct filtration process. Raw water enters the plant from the Naches River intake via a 54 inch raw water transmission main. The main is reduced in size and controlled by a 36 inch influent valve OPERATING MODES AND ALTERNATIVES Chemicals are applied at the pump flash mix, which provides a mixing time of approximately 2 5 minutes The chemically treated water discharges into one of two contact basins with a total detention time of about 30 to 75 minutes. The effluent from the contact basin flows to the filters, which discharge to a very small clearwell. (Please refer to the treatment process schematic ) The chemicals available to be used in the treatment process include aluminum chlorohydrate (ACH) as a primary coagulant, cationic polymer as a coagulant aid, non-ionic polymer as a filter aid, powdered carbon for taste and odor control, caustic soda (sodium hydroxide) for pH control and sodium hypochlorite (chlorine) for disinfection. The backwash water storage reservoir has a capacity of 750,000 gallons of finished water for use in backwashing the filters. After backwashing this water is wasted to the waste lagoons for storage and further settling before being pumped back into the main stream of the treatment system prior to the hydraulic mixer for the addition of chemicals. Should the treatment facility become unable to produce water which meets or exceeds all of the drinking water standards, then the plant is to be placed out of service and the procedures for loss of supply followed. Should components of the Water Treatment Plant cease to function, the following alternatives may be utilized: FLASH MIX: Make adjustments to the chemical feed pumps to increase the chemical dosage and rely on hydraulic mixing of the chemicals CONTACT BASIN: there are two basins and may be operated separately FILTERS: Four filters are available and a maximum of three may be isolated at one time. BACKWASH RESERVOIR: The reservoir may be isolated through utilization of the 24 inch butterfly valve installed between the WTP and the reservoir (valve is marked) The backwash refill pumps are then used to pump water directly from the clear well to the filters for washing. A small 3 horsepower pump and the appropriate fittings are stored at the WTP to provide service water under the above conditions WASTE LAGOONS: All backwash water is diverted directly to the new waste lagoons through the backwash water pump station The recycling of waste lagoon water can be adjusted (gpm adjustment) on the SCADA system. In the case of a level control failure in the backwash flow pump station, it will be necessary for the operator to open all doors in pump station to drain any standing water in pump station, adjust pump VFD settings to keep up with flow from backwash production, and call in back up for operational assistance. Once the flood situation has been controlled, it will be necessary to contact Conley Engineering to have them troubleshoot the cause of the level control failure CHLORINATION: One option should the chlorine generator be unavailable is to purchase 12.5% sodium hypochlorite (barrels) and dilute with dilution system to 0.8% solution an fill NaOCL storage tanks. Should there continue to be a problem with the chlorine generator, use the remainder of the 0 8% solution in the solution tanks then shut down the WTP and start wells. -- 32 -- Emergency Op Guidelines STAFF INSTRUCTIONS FOR SCADA, REMOTE TELEMETRY LOSS OF FUNCTION, OR PHONE OUTAGE POSSIBLE • Computer / server failure CAUSES: • Telemetry radio failure • Phone outage ALTERNATIVE 1: If loss of SCADA at the WTP occurs it will be necessary to determine if there is adequate water storage. If there is ample storage, contact Conley Engineering to determine cause of loss of SCADA. 1. If loss will be for a short time, determine if wells need to be started 2 Visually monitor reservoir levels and manually control pumps at pump stations if necessary ALTERNATIVE 2: If you determine that water from storage will not meet demand during the expected duration of the SCADA outage and wells will not keep up with demand, the plant can be operated manually. (Note: it will be necessary for operator to call in other personnel to assist with operation manually) 1 All Auma actuators for plant influent valve and all filter effluent valves can be operated manually or in "local". 2. Flow can be monitored on the influent side of the plant as well as the effluent side of the plant by monitoring mag meter flows at the read outs for each flow meter 3. All chemical feed pumps can be operated in "local" mode and adjusted for speed according to what the chemical analyzers and operator determine is necessary to raise or lower chemical feed 4. In the case of washing a filter; • it will be necessary to close any Auma actuated valve (on filter) by hand or in "local" • open waste valve on air manifold • drain filter to just above surface wash sweeps using the "local" switch and hand turning valve on filter to waste valve to approx 3 00 MGD Close the Filter to waste valve by hand or "local" • start surface wash pump in "hand" • open filter backwash valve on air manifold in pipe gallery • operate backwash / filter to waste pumps in pump station by hand on VFD to maintain flow to waste lagoons • monitor filter backwash level (once level is just below top of wash troughs, turn off surface wash pump) • open main filter backwash valve manually in "local" at the Auma • monitor filter backwash level (once level is just below top of wash troughs, turn off surface wash pump) • raise backwash flow rate to proper flow rate according to water temperature • once the filter has been washed to desired clarity, follow normal hand wash filter return to service procedure operating the proper valves by hand and not from control panel. 5 All plant components (i e air compressors, Auma valve actuators, backwash refill pumps, wash pumps, recycle pumps, constant visual inspection of turbidity levels through filters, etc.) will have to be operated and inspected manually 6 All remote facilities will have to operated by hand and through visual inspection 7. Once SCADA is restored, all components can be returned to normal automatic operation with the assistance of Conley Engineering -- 33 -- Emergency Op Guidelines ALTERNATIVE 3: Loss of telemetry at remote sites 1. Use laptop from WTP and "Bird" meter to determine if remote radios are functioning correctly 2. If radios are not functioning correctly, run diagnostic checks to determine problem 3. If troubleshooting determines problem is beyond our capabilities, call Conley Engineering 4. Continue to visually monitor and operate reservoirs, pump stations, and wells as necessary 5. Return to normal operations as radio problems are resolved ALTERNATIVE 4: Landline (phone) Outage at WTP 1 Assure that the plant cell phone is charged and with the operator at all times 2. Contact Fire Dispatch (575-3014) and apprise them of the situation. If they receive any water or irrigation calls have them contact the WTP cell phone immediately 3. Contact Police Dispatch (575-3012) and apprise them of the situation. If they receive any water or irrigation calls have them contact the WTP cell phone immediately 4. Contact Century Link (800-788-3600) to determine how long the outage duration may be 5 Once phone service has been restored, contact both Fire and police Dispatch to let them know you have full service once again (Water Treatment Plant Process Schematic Chart — See Appendix F) STAFF INSTRUCTIONS FOR WTP LOSS OF FUNCTION POSSIBLE • Damage from flooding. CAUSES: • Raw water turbidity too high for effective treatment or low winter temperatures cause slush ice and prevent water conveyance from intake to WTP ALTERNATIVE 1: If determination is made that loss of the facility is expected to be of short duration and that adequate supply is available from storage simply isolate the plant and shut down. -- 34 -- Emergency Op Guidelines PROCEDURE: 1 Isolate the plant and shut down Sand bag around WTP structures if necessary 2. Log time of day and reason for shut down 3. Start emergency wells as necessary ALTERNATIVE 2: If you determine that water from storage will not meet demand during the expected duration of the WTP outage, proceed to follow the instructions for loss of supply. PROCEDURE: See "Loss of Supply" instructions in this manual. CITY OF YAKIMA MAJOR FACILITIES - DISTRIBUTION SYSTEM AND STORAGE RESERVOIRS DESCRIPTION The City's distribution system is adjacent to several water systems, but is only intertied with the Nob Hill Water Association. Two interties exist with Nob Hill Water Association. Nob Hill Water interties are located in the high zone pressure area at the intersection of 56th Avenue and Lincoln Avenue and at S 32nd Ave and Ahtanum Road. The distribution pipelines are 4 to 24 inches in diameter The pipe materials are mainly cast iron, with ductile iron being used since the early 1970's. There are several steel pipelines and many unlined cast iron pipelines remaining in the system The City's existing storage capacity is 32 million gallons (MG) distributed among five reservoirs within the three pressure zones Each pressure zone has an established hydraulic elevation This elevation is maintained by the distribution reservoir/s located in each of the pressure zones. The City's existing instrumentation and control (I&C) system located at the WTP monitors and controls the functions of the distribution system and storage reservoirs. Note: The reservoirs are shown on the hydraulic profile in Appendix C. The table indicates the volume of storage, the zone served, type of construction, and the overflow and floor elevation of the five reservoirs in the distribution system. OPERATING MODES AND ALTERNATIVES The function of the distribution system is to deliver potable water to domestic service connections, as well as fire flow to fire hydrants and fire suppression systems. The function of the storage reservoirs is to provide 1) standby water storage for emergencies and short-term interruptions of source of supply; 2) additional source of water for fire protection purposes; 3) equalizing water storage for changes in water demands within the system Distribution pipelines branch off from the transmission mains, conveying water to the three pressure zones -- high, middle, and low Gravity alone provides adequate pressure to serve water to the low zone Booster pump stations transfer water up to the reservoirs in the middle and high zones, and pressure -reducing valves (PRV's) regulate water flows back from the middle to the low zones when necessary Normally, closed valves may be operated to move water from the high zone to the middle zone Conversely, portions of the high zone could be served (at lower pressure) from the middle zone through operation of these normally closed valves and existing check valves The six million gallon reservoir at 40th Avenue and Englewood Avenue is utilized as an equalizing reservoir for the entire water system The flow at the WTP is based upon levels in this reservoir Any water not consumed by -- 35 -- Emergency Op Guidelines the low pressure zone through customer demand, or by pumping to the middle and high pressure zones, is stored here Should the distribution system cease to function in specific areas, these areas may be isolated by closing valves to sections as needed according to the distribution grid system serving the affected area. Should the entire distribution system fail to function, then water would need to be hand carried or transported by vehicle. No fire protection would be available from the system. Fire Department tankers would have to be utilized for fighting fires Potable water would need to be made available at distribution points throughout the system. The Yakima Firing Center, the National Guard, and private carriers may be pressed into service in an emergency Fire stations, City parks, and other City properties shall be utilized for distribution of potable water. City residents would be notified of these distribution points and instructed to bring containers to receive their allotment of water. The source of water for supplying the distribution points could be the Kiwanis, Airport, and Gardner artesian wells (if flowing) Additionally, potable water could be purchased from adjacent purveyors that still have a safe plentiful supply Should the storage reservoirs cease to function, the system's ability to meet all demands would become undependable. Some fire fighting capability might be retained but not to normal standards. The interties with Nob Hill Water Association could be utilized to place their reservoirs into shared operation The reservoirs could be isolated and water supply pumped directly into the system from the wells or by gravity from the WTP. The 48" transmission main could act as a reservoir during an emergency. During extended emergencies portable storage reservoirs or temporary reservoirs could be utilized to accomplish the same function as a storage reservoir. STAFF INSTRUCTIONS FOR DISTRIBUTION SYSTEM AND STORAGE RESERVOIR LOSS OF FUNCTION POSSIBLE • Earthquake CAUSES: • Sabotage • Nuclear disaster ALTERNATIVE 1: Should localized areas of failure be determined, isolation of these areas of the distribution system or storage reservoirs is in order to reduce property damage from escaping water and maintain the system integrity. PROCEDURE: 1. Notify the Fire Department of the extent of service they may expect from the system and the approximate duration of this service level 2. Check water system maps and records for locations of system valves to be utilized in isolating the affected area or structure 3. Proceed to the valves and operate them into closed position. 4. Depending upon the volume of water escaping, notify the customers in the affected area either before or after isolating the area 5. Determine amounts of damage to the affected areas. 6. Determine methods and estimate the cost of repairs. -- 36 -- Emergency Op Guidelines 7 Costly repairs (greater than $7,500) need management approval and assistance from Purchasing 8 Institute water rationing and a distribution point program within the affected areas if repairs cannot be made immediately. 9 Make repairs or replace the portions of the distribution system and storage reservoirs that have failed. 10 Disinfect the main repairs and/or replacements made during restoration Flush the mains and take a bacteriological sample. Receive a negative report on the bacteriological sample before returning the system back into service ALTERNATIVE 2: Should complete failure of the distribution system and/or storage reservoirs occur, water rationing and potable water distribution points would need to be established to provide customers with a safe drinking water supply. PROCEDURE: 1. Notify the Fire Department that no water supply is available from the system. 2. Notify the customers that the water supply is not safe or reliable and that water rationing is in effect 3 Boil water notice if necessary 4 Determine sources and methods of distributing a potable water supply to the customers. 5 Distribute information regarding the locations of potable water supply to the customers. 6. Determine what portions of the system are salvageable and determine methods and costs to repair and/or replace the damaged portions of the system. 7. Implement repair and/or replacement program. ALTERNATIVE 3: Should only the storage reservoirs cease to function, they should be isolated and the system operated on a limited basis without benefit of storage reservoirs. PROCEDURE: 1. Notify the Fire Department that a reduced amount of water supply is available from the distribution system 2. Notify the customers that the system use is curtailed and water rationing is in effect. 3. Boil Water notice if necessary 4 Determine best method to utilize under the disaster circumstances a) utilize Nob Hill Water Association's storage reservoirs; b) place water directly into the distribution system without benefit of storage, c) construct or utilize temporary storage facilities through the use of portable reservoirs or open excavations with plastic or vinyl linings -- 37 -- Emergency Op Guidelines CITY OF YAKIMA MAJOR FACILITIES -- BOOSTER PUMPING STATIONS DESCRIPTION The pump stations are listed in Appendix C, showing the location, the supply, the pressure zone served, the number of pumps in each station and capacity, and other characteristics. OPERATING MODES AND ALTERNATIVES The booster pump stations provide water to the middle and high zones, as shown in the hydraulic profile The 40th Avenue and Stone Church pumps are operated in a variety of lead lag positions depending on the demand and the season The difference in water demands is due to an irrigation demand in the middle and high zones These pumps are controlled by the middle zone's two reservoir levels through the radio telemetry system. The high zone pumping station is only capable of operating one of the 125 hp pumps at a time This is due to the size of the electrical service available when the facility was constructed. The two 125 hp pumps are alternated with one placed in a standby role, while the other is being used and with the 30 hp pump placed in the lag position The smaller 30 hp pump is placed in the lead during low demand times This station's pumps are controlled by the water levels in the high zone's two reservoirs through the radio telemetry system. The Gleed pumping station is operated by utilizing the two 5 HP pumps to meet domestic water demands and the 125 HP pump for fire flow demands. This station's pumps are controlled by pressure sensing controls and a hydropneumatic tank At 55 psi the lead pump will start and run until pressure builds to 75 psi The lag pump starts at 45 psi 125 HP fire pump comes on at 30 psi; and run until it has 90 psi for 12 minutes. A pressure relief valve is located in the manifold system and allows the bypass of water back into the 48" transmission main of any water in excess of 100 psi Should the 40th Avenue and Stone Church pump stations cease to function, the available supply in the twin twelve (12) million gallon reservoirs needs to be determined. If additional water supply is needed to meet demands, Nob Hill Water Association may be contacted to furnish water through the emergency intertie in the high zone, then put into the middle zone through normally closed valves or PRV's Should the station cease to function because of an electrical power outage, a portable electrical generator might be used to restore electrical power to the 40th Ave. pump station and/or depend on the generator at the Stone Church pump station. PUMP STATIONS Should the High Zone Pump Station cease to function, the available supply in the twin one (1) million gallon reservoirs need to be determined If additional water supply is needed to meet demands, the Nob Hill Water Association may be contacted to furnish a source of water through the emergency intertie at N.56th Avenue and Lincoln Avenue Should the station cease to function because of an electrical power outage, the electrical generator should be used to restore electrical power to the site Should the Gleed pump station cease to function, the customers are without a water supply at adequate pressure (greater than 30 psi). However, as long as the 6 million gallon reservoir at N.40th Avenue and Englewood Avenue is capable of maintaining at least a minimum level of 11 feet, there is a positive pressure at Gleed. Currently, there are approximately twenty five customers served by this pump station Water supply for domestic purposes would continue to be available at low pressure (10-15 psi). A local carrier with a food grade tanker may be filled with water and connected to the fire hydrant near the Naches Primary School to supply the Gleed System The Gleed Fire Department should be notified immediately if the station is to be out of service for any length of time. This rural department has the capability of fighting fires without adequate water supplies available close at hand through use of tanker trucks and can dispatch additional tanker units if necessary -- 38 -- Emergency Op Guidelines STAFF INSTRUCTIONS FOR BOOSTER PUMPING STATIONS LOSS OF FUNCTION POSSIBLE • Severe Storms, Earthquakes, Volcanoes, and other natural disasters CAUSES: • Sabotage • Nuclear Disaster • Electrical Power Loss • Loss of PLC or Controls (All pump stations and wells, including backwash pump station and WTP) ALTERNATIVE 1: Should any of the booster pumping stations fail, the duration of the failure and available water storage must be determined. If the determination is that an additional water source will be needed to meet demands prior to placing the stations back in service, then the emergency interties(s) with the Nob Hill Water Association must be activated. PROCEDURE: 1. The WTP personnel will note the time of booster pumping station failure. Verify available water storage and supply demand 2. Proceed to the booster pumping station and make a preliminary inspection for possible causes of the loss of service 3. If possible, determine cause of problem and estimate duration of time the pumping station will be out of service Make repairs as required to restore normal service 4 Determine if additional water supply will be necessary and estimate quantity needed to satisfy demand 5 Contact Nob Hill Water Association and Emilio Lopez, Water Distribution Supervisor, for implementation of the appropriate emergency interties. 6 Make repairs as required to restore normal service ALTERNATIVE 2: Should the booster pumping stations fail due to the loss of electrical power and / or loss of PLC or controls, and it is determined that the loss will be of a significant duration; secure portable electric power generation equipment and temporarily restore electrical power at Gleed Pump Station and/or start generator at the High Zone Pump Station and/or Stone Church Pump Station. -- 39 -- Emergency Op Guidelines PROCEDURE: 1 Secure an adequately sized portable generator for the pump station (Gleed 250 KW) 2 Contact a local electrical contractor for assistance in disconnecting the normal power supply and reconnecting the emergency power supply. Should the loss of PLC or electrical controls be the issue, it will be necessary to contact Conley Engineering as soon as possible to restore PLC / control function It may be necessary for an operator to reconnect the remote access port so engineer might troubleshoot the issue before leaving their office. NOTE: The network switch and patch panel is behind the control panel off of the control room at the WTP. This is the first Ethernet connection rack on the left as you walk behind the control panel. To reconnect the remote access port, follow this procedure; The Red wire from port 7 on the City Switch connects to TIE -11 on patch panel just below and the Red wire from port 8 on the City Switch connects to TIE -12 on the patch panel just below. These connections will have to be disconnected after remote access is no longer needed. 3. Monitor the operation of the emergency power supply until the normal power supply is restored. 4. Contact a local electrical contractor for assistance in disconnecting to emergency power supply and reconnecting the normal power supply 5. Return the portable power generating equipment to its owners. CITY OF YAKIMA MAJOR FACILITIES -- PRESSURE REDUCING VALVE STATIONS DESCRIPTION The PRV locations are listed in Appendix G, indicating the location, size, pressure settings, the zone that is served and some additional information. The valves listed as "not in service" have been made redundant through changes in the boundaries of the pressure zones and are no longer required. OPERATING MODES AND ALTERNATIVES Control of water flow between the middle and low pressure zones is provided by the PRV's located throughout the distribution system These control valves are set to open and close at various hydraulic elevations depending on the intended purpose of the valve (continual supply or emergency only). The normal use of the City's PRV's is to provide additional water flow for emergency purposes. The reduction of pressure in the low zone under emergency conditions because of a fire flow or other large water demand will cause the hydraulic elevation to decrease This reduction in hydraulic elevation will cause the normally closed hydraulically actuated valves to open and provide additional flow into the low zone. Should the PRV stations cease to function, the valves may be manually open or closed The effects of the PRV stations having failed are 1) Water movement between zones which will result in losses and increases in water pressure in the distribution system, if failure is in the open position. 2) Inadequate water flows during an emergency or other high demand situations, should the valve fail in the closed position. -- 40 -- Emergency Op Guidelines STAFF INSTRUCTIONS PRV STATIONS LOSS OF FUNCTION POSSIBLE • Sabotage CAUSES: • Freezing • Mechanical Malfunctions ALTERNATIVE 1: Isolate the PRV stations that have failed. PROCEDURE: 1. Determine which station(s) has/have failed by checking each station individually. 2 Determine problem and attempt repairs or manually activate the valves either open or closed. 3. If you fail in attempting to make repairs, isolate the valve(s) with the gate valves provided. 4. Complete repairs as soon as possible. Parts are stocked at the Water/Irrigation Division Warehouse 5. Place the station(s) back in service. CITY OF YAKIMA MAJOR FACILITIES -- ELECTRICAL POWER SUPPLY DESCRIPTION The source of the electrical power supply for the City of Yakima Water System is the PacifiCorp. All of the water system facilities are dependent upon electrical energy OPERATING MODES AND ALTERNATIVES The function of the water system's power supply is to provide the electrical energy necessary to operate the multitude of electrically powered equipment necessary for operation of the water system. With the loss of electrical energy, the Water Treatment Plant, booster pumping stations, wells, telemetry control systems and telephonic communications may be affected; depending on the extent of the loss of power. Should the water system's power supply cease to be available, the following alternatives may be utilized to augment or accomplish the same function. 1. Contact the PacifiCorp to determine the extent of the power outage and the length of time the loss of power is expected to last. Local Dispatch 575-3134. 2 Secure portable electrical generators to serve as a temporary power supply for the affected facility 3. Utilization of the natural artesian well head pressure at the Kiwanis well, Airport well, and Gardner well is only adequate if these wells are flowing STWIV A -- 41 -- Emergency Op Guidelines May 11, 2016 STAFF INSTRUCTIONS FOR ELECTRICAL POWER SUPPLY LOSS POSSIBLE • Severe storms, earthquakes, volcanoes, and other natural disasters CAUSES: • Nuclear disaster • Sabotage of electrical generation facilities • Overload / Failure of electrical system • Loss of PLC or Controls (All pump stations and wells, including backwash pump station, and WTP) ALTERNATIVE 1: Contact PP&L PROCEDURE: 1. Attempt to telephone PP&L at 575-3133. If telephone communication is not possible, wait for normal business hours and personally contact them at their offices on North 16th Avenue or 7 North 3rd Street 2 Secure from PP&L their estimate of the area affected by the power outage and the estimate of the length of time the outage is expected to last. 3 Using this information, along with the amount of water in storage at the time of the loss of power and the average daily system demand, determine if the water in storage is inadequate to meet the needs during the outage 4. If the electrical power is to be restored prior to the stored water levels, dropping below one days reserves then simply wait for restoration of the power supply If the loss of power will exceed this time frame, then implement the water rationing procedures outlined under "loss of supply" in this guide 5. When the loss of power supply is isolated to one or a few facilities, attempt to utilize an alternative to that particular facility or facilities (see Major Facilities in this guide) ALTERNATIVE 2: Secure portable electrical generators to serve as temporary power supplies for the affected facility. Note: There are generators at the WTP, 3rd Level Pump Station, and Stone Church Pump station. PROCEDURE: 1. If only the Water Treatment Plant is affected, then treat the emergency as a "loss of supply" and follow the instructions as outlined in this guide 2. Secure a generator from a local machinery vendor, Yakima Firing Center or the Washington State National Guard STWIV A -- 42 -- Emergency Op Guidelines May 11, 2016 3. Once you have secured a generator, contact the or a private electrical contractor to disconnect the electrical service from PP&L and reconnect to the temporary power supply. Should the loss of PLC or electrical controls be the issue, it will be necessary to contact Conley Engineering as soon as possible to restore PLC / control function It may be requested by the Engineer for an operator to reconnect the remote access port so that they may troubleshoot the issue before leaving their office NOTE: The network switch and patch panel is behind the control panel off of the control room at the WTP. This is the first Ethernet connection rack on the left as you walk behind the control panel. To reconnect the remote access port, follow this procedure; The Red wire from port 7 on the City Switch connects to TIE -11 on patch panel just below and the Red wire from port 8 on the City Switch connects to TIE -12 on the patch panel just below. These connections will have to be disconnected after remote access is no longer needed. 4 Gleed System existing power requirements 250 KW 5 Operate the pump station under these conditions until PP&L has completely restored a reliable power source. Contact the electrical technicians to disconnect the emergency power source and reconnect to PP&L's system. 6. Return the portable generator to its owner. ALTERNATIVE 3: Utilization of artesian wells.

The RWPC and the City of Yakima are taking a proactive approach to wellhead protection planning to ensure that each community's groundwater supplies are adequately protected from potential contamination sources on the ground surface. The purpose of this letter is to notify you of the location of your business within one of the City's wellhead protection areas and provide you with information on how you can help protect the City's drinking water supplies. Wellhead protection planning includes the following four elements: • Development of wellhead protection areas, or areas which may be susceptible to contamination • Identification of potential contamination sources, which include septic tanks, underground storage tanks, abandoned wells, and certain businesses • Coordination of management efforts to help minimize the impact of potential contamination sources, including posting of signs, distribution of literature, and public education efforts • Development of contingency planning to ensure that prompt response procedures are in place in the event that a well becomes contaminated The RWPC and the City understand that most business owners recognize the need to protect the environment in and around your business. We hope that informing you of the location of business within the City's wellhead protection area will result in an increase in precautions to ensure your activities do not adversely impact our drinking water supply. The following practices can greatly reduce the threat of contamination to groundwater supplies: • Recycle all hazardous wastes used on the premises including solvents, paints, cleaners, printing supplies, or other chemicals through Yakima County's free small quantity generator or recycling programs (574-2450). • Reduce the amount of hazardous waste used through waste minimization efforts. Free literature on waste minimization is available from the Department of Ecology (DOE) and your local water purveyor. • Conserve water whenever possible. Water conservation reduces waste volumes and reduces the threat of contaminant transport.

Wellhead protection planning includes the following four elements: 1 development of wellhead protection areas, or areas which may be susceptible to contamination 2. identification of potential contamination sources, which include septic tanks, underground storage tanks, abandoned wells, and certain businesses 3. coordination of management efforts to help minimize the impact of potential contamination sources, including posting of signs, distribution of literature, and public education efforts 4. development of contingency planning to ensure that prompt response procedures are in place in the event that a well becomes contaminated The RWPC and Nob Hill Water understand that most property and business owners recognize the need to protect the environment We hope that informing you of the location of your property or business within Nob Hill Water's wellhead protection area will result in an increase in precautions to ensure your activities do not adversely impact our drinking water supply. The following practices can greatly reduce the threat of contamination to groundwater supplies: • Recycle all hazardous wastes used on the premises including solvents, paints, cleaners, printing supplies, or other chemicals through Yakima County's free small quantity generator or recycling programs (574-2450). • Reduce the amount of hazardous waste used through waste minimization efforts. Free literature on waste minimization is available from the Department of Ecology (DOE) and the City of Yakima. • Conserve water whenever possible. Water conservation reduces waste volumes and reduces the threat of contaminant transport.

STATE OF WASHINGTON DEPARTMENT OF HEALTH EASTERN DRINKING WATER REGIONAL OPERATIONS 16201 E Indiana Avenue, Suite 1500, Spokane Valley, Washington 99216-2830 TDD Relay 1-800-833-6388 December 3, 2014 David E. Brown, Water / Irrigation Manager City of Yakima Water Division 2301 Fruitvale BLVD Yakima, WA 98902 Subject: Yakima Water Division, City of; PWS ID #991509; Yakima County Sanitary Survey — October 16, 2014 Dear Mr. Brown: I would like to thank your operators for your time and help with the Department of Health (DOH) Routine Sanitary Survey, on October 16, 2014. I documented our discussion and observations during the survey, in the enclosed report including photographs. Significant Deficiencies We inspected the groundwater and surface water sources (S01, 502, S03, S08, and 510), as well as, the middle level reservoirs. During the survey, we observed the following Significant Deficiencies. Please correct and provide a brief letter, documenting how you had each deficiency corrected, within 45 days of the date of this letter. Please note: we must receive your responses no later than January 19, 2015. 1, S08 (Kissel Well) — The well was not properly covered when the pump column and motor were removed from the well. The casing is a direct conduit to the aquifer and falling debris, chemicals, and such which can quickly contaminate the aquifer. You can see from the pictures provided in the report, the well casing is not completely covered and the hole is large enough for small animals to access and fall down the well. 2. Reservoir inspections: Damien and I inspected the middle reservoirs, and discussed what needed to be documented with the inspections on the remainder of the reservoirs. Please note the following on the reservoirs inspected by your staff * The vent is designed appropriately, and the screen is in good condition. * The hatch is framed from the reservoir roof, has a locking cover, the cover over laps the framed portion of the hatch, and the gasket is still in good condition. No other potential holes or gaps around control wires, for example, where rain water, windblown dust, insects, or other potential contaminants can enter the reservoir. The state's drinking water program has made it a high priority to make sure all water systems correct each Significant Deficiency discovered during a survey. Please mail your brief letter and photographs to Danielle Russell, at our address provided on our letterhead or by email at David Brown December 3, 2014 Page 2 danielle.russell@doh.wa.gov. We have logged the completion date and deficiency into our survey database. If necessary, our office will take enforcement action if we do not receive your letter by the deadline listed above. Survey Fee Our office will schedule a water system's survey once every three to five years. WAC 246-290- 990 (3)(c), authorizes a schedule of fees to be implemented to help recover the cost of conducting a sanitary survey. The Department of Health's (DOH) total cost to complete this sanitary survey is $1,583.87. The Office of Drinking Water has used state and federal funds to pay $359.87 of this amount. An invoice showing the remaining amount due of $1,224.00 is enclosed. Discussion Items I provided information on the following water quality monitoring changes, since the last sanitary survey, as well as, documentation needed for the reservoir inspection. A. Groundwater Rule: General information on the rule and additional requirements triggered when a coliform sample tests positive for coliform.

The Contractor shall have a representative with authority on site whenever work is being performed Any problems that are encountered or changes required due to construction conditions will be reviewed with the Consulting Engineer and the owner/developer. Changes that require any increase or decrease to the contractor's cost will be the responsibility of the owner/developer and may result in increased City review and inspection fees All construction shall meet the requirements of the most current edition of the WSDOT Standard Specifications for Road, Bridge, and Municipal Construction, the Department of Health Design Manual, the Criteria for Sewage Works Design with the Department of Ecology, the Stormwater Management Manual for Eastern Washington or an approved stormwater manual for the Yakima area, Yakima City Standards, the approved plans, the approved Project Specifications and other applicable regulations. Special Provisions (project -specific specifications) shall be prepared and submitted to the City for acceptance All changes, alterations, or revisions to the approved plans or specifications shall be submitted for acceptance by the City Engineer. Copies of all test records shall be furnished to the City Engineer on a weekly basis, or as deemed necessary by the City Engineer The City Engineer or designee will visit the project site to review the work related to the required inspection. Such site visits do not relieve the applicant, or the contractor of any responsibilities for performing all work in accordance with the approved plans and this chapter The City Engineer or designee may also visit the project site from time to time to monitor the overall progress of the project Failure to comply with testing requirements may necessitate appropriate or additional testing and certification as directed by the City Engineer Costs of such testing and certification shall be borne by the contractor and/or applicant At the time that such action is directed by the City Engineer, no further work will be permitted on the road or subdivision until all tests have been completed and all corrections have been made to the satisfaction of the City Engineer. The City shall have the authority to cause a suspension of construction when, in the City's opinion, such work is not being done in conformance with the approved plans, specifications, regulations or permit. Any resultant delays, impacts or added expenses shall not be the City's responsibility Step VII Upon written notice that the public improvements have been substantially completed, the City will, in the company of the Owner/Developer or his Agent, make a final inspection of the construction. Such inspection shall include the checking of valve box alignment and the operation of valves. The Owner/Developer shall see that all necessary additions, corrections, repairs, and/or modifications are made Title 12 Procedures Manual Update — May 8, 2013 5 Step VIII At the conclusion of construction and when all corrections and repairs have been made, the Owner/Developer shall submit one full reproducible set and an electronic pdf of the "As Built" Record Drawings together with a Certificate of Work Completion, which shall include, but not be limited to, testing records, material certifications and warranties, and a request for acceptance by the City.
