The Parties acknowledge that they have mutually negotiated this waiver. 7.4.3 Should a court of competent jurisdiction determine that this Agreement is subject to RCW 4.24.115, then, in the event of liability for damages arising out of bodily injury to persons or damages to property caused by or resulting from the concurrent negligence of the ENGINEER and the City, the ENGINEER's liability, including the duty and cost to defend, shall be only to the extent of the ENGINEER's negligence. 7.4.4 Nothing contained in this Section or this Agreement shall be construed to create a liability or a right of indemnification in any third party. 7.4.5 The terms of this Section shall survive any expiration or termination of this Agreement. 7.5 In any and all claims by an employee of the ENGINEER, any subcontractor, anyone directly or indirectly employed by any of them, or anyone for whose acts any of them may be liable, the indemnification obligations under this Agreement shall not be limited in any way by any limitation on the amount or types of damages, compensation, or benefits payable by or for the ENGINEER or a subcontractor under workers' or workmens' compensation acts, disability benefit acts, or other employee benefit acts. The ENGINEER specifically and expressly waives its immunity under the Industrial Insurance Act, Title 51, RCW. Such waiver has been mutually negotiated by the ENGINEER and the CITY. 7.6 It is understood that any resident engineering or inspection provided by ENGINEER is for the purpose of determining compliance with the technical provisions of PROJECT specifications and does not constitute any form of guarantee or insurance with respect to the performance of a contractor. ENGINEER does not assume responsibility for methods or appliances used by a contractor, for a contractor's safety programs or methods, or for contractors' compliance with laws and regulations. CITY shall use its best efforts to ensure that the construction contract requires that the contractor(s) indemnify and name CITY, the CITY's and the ENGINEER's officers, principals, employees, agents, representatives, and engineers as additional insureds on contractor's insurance policies covering PROJECT, exclusive of insurance for ENGINEER professional liability. 7.7 ENGINEER shall be solely responsible for and shall pay all taxes, deductions, and assessments, including but not limited to federal income tax, FICA, social security tax, assessments for unemployment and industrial injury insurance, and other deductions from income which may be required by law or assessed against either party as a result of this Agreement.

Page 5 8 7.8 SUBSURFACE INVESTIGATIONS: In soils, foundation, groundwater, and other subsurface investigations, the actual characteristics may vary significantly between successive test points and sample intervals and at locations other than where observation, exploration, and investigations have been made. Because of the inherent uncertainties in subsurface evaluations, changed or unanticipated underground conditions may occur that could affect total PROJECT cost and/or execution. These conditions and cost/execution effects are not the responsibility of the ENGINEER, to the extent that ENGINEER has exercised the applicable and appropriate standard of professional care, thoroughness and judgment in performing such investigations.

The performance dates and budgets for tasks may be modified only upon written agreement of the parties hereto. The performance date for tasks and the completion date for the entire PROJECT shall not be extended, nor the budget increased because of any unwarranted delays attributable to the ENGINEER, but may be extended or increased by the CITY in the event of a delay caused by special services requested by the CITY or because of unavoidable delay caused by any governmental action or other conditions beyond the control of the ENGINEER which could not be reasonably anticipated or avoided. 8.2 Not later than the tenth (10'h)day of each calendar month during the performance of the PROJECT, the ENGINEER shall submit to the CITY's Representative a copy of the current schedule and a written narrative description of the WORK accomplished by the ENGINEER and subconsultants on each task, indicating a good faith estimate of the percentage completion thereof on the last day of the previous month.

Nob Hill Blvd,Yakima,Washington 98902 Proposal and Scope of Work for Task 1 Sub-Slab Depressurization System (SSDS) Pilot Testing and Design Haley& Aldrich, Inc. (Haley& Aldrich) is pleased to submit this proposal for engineering and environmental services in connection with the above-referenced site (the Site). Project Understanding The Site (Washington State Department of Ecology [Ecology] Facility Site No.469, Cleanup Site No. 4919) is located at 2312 West Nob Hill Boulevard, in Yakima, Washington. Site is specific to where contamination resulting from former operations at the former Tiger Oil facility (the Property) has come to lie, irrespective of property boundaries. A retail gasoline station had operated on the Property from 1978 until 2001. Currently, there are no commercial activities at the gravel-surface undeveloped Property. Several fuel releases at the Property during its active facility operations had resulted in gasoline petroleum fuel impacts to soil and groundwater at the Property as well as to the adjoining parcels to the east, south, and southeast (the Site—Figure 1). Interim remediation and groundwater monitoring activities conducted at the Site are conducted under Amended Consent Decree No.02-2-00956-22. The Property is owned by Heyden Properties, LLC (Heyden Properties).The City of Yakima was formerly the property owner until 2019.The Property is currently zoned as "B-2"with designation of future land use as Community Mixed Use. Access to the Property is from West Nob Hill Boulevard and South 24th Avenue, adjacent north and west, respectively, of the Property. Until it was purchased by Tiger Oil Corporation (New Tiger) in 1987, the Property was operated by the Tiger Oil Company as a retail fuel station. New Tiger operated the Property as an Exxon-branded fuel station and convenience store from 1987 until 2001. All commercial operations ceased in 2001 and the Property has remained vacant since (Ecology, 2021).The fuel station included four underground storage 21 City of Yakima 5 October 2022 Page 2 tanks (USTs) (one 20,000-gallon, two 10,000-gallon, and one 8,000-gallon tank) and associated product lines. The system was used for bulk petroleum storage and distribution. It was estimated that approximately 20,000 gallons of petroleum-related product had been released from the Property's UST system in the early 1980s. Several recovery wells had been installed by early 1983 at the Property and on adjacent parcels to the east and south. By March 1984, approximately 16,000 gallons of LNAPL had been extracted from the recovery wells (Ecology, 2021). Groundwater monitoring was being conducted on a semiannual basis at the Site. Figure 1 presents the location of monitoring wells at the Site. Groundwater monitoring events in 2021 indicated that LNAPL thicknesses had ranged from 0.005 to 2.79 feet within the source area at the Property and at immediate area downgradient to the east-southeast. Figure 2 presents the estimated extent of residual LNAPL. Groundwater analytical results of the 13 compliance monitoring wells sampled during the May 2021 monitoring event indicated that gasoline-range total petroleum hydrocarbons (TPHs) exceedances ranged from 1,800 micrograms per liter (ug/L) to 15,000 ug/L, above the Washington State Model Toxics Control Act (MTCA) cleanup level (CUL) of 800 ug/L. Groundwater analytical results also showed that benzene exceedances had ranged from 5.1 ug/L to 680 ug/L—above the MTCA Method A CUL of 5 ug/L. The core of the dissolved-phase plume includes monitoring wells exhibiting the highest concentrations of gasoline-range TPH and benzene, toluene, ethylbenzene, and total xylenes (BTEX) constituents. Monitoring wells YMW-1,YMW-2, YMW-3, MW-13, and S-2 are adjacent to and/or downgradient of the area where residual petroleum-contaminated soil was not accessible during the interim remedial action Figure 2). Additionally, groundwater at the Site is also impacted by halogenated VOCs, typically associated with solvents from dry cleaning operations. Groundwater at the Site exhibits detections of tetrachloroethene (PCE), at concentrations (11 ug/L to 28 ug/L) above the MTCA Method A CUL(5 ug/L). Vinyl chloride, a breakdown product of PCE, was also exhibited at concentrations (0.63 ug/L and 0.98 ug/L) above its MTCA Method A CUL(0.5 ug/L) (Ecology, 2022). It is our understanding that indoor air quality assessment at the three adjoining businesses (Xochimilco Mexican Restaurant, Barber HQ, and 1Up Games) to the Property) has indicated the presence of gasoline-range TPH, benzene at concentrations above Ecology Indoor Air Method B Cancer CULs.and PCE and trans-1,2-dichloroethene were detected at the Xochimilco Mexican Restaurant (Xochimilco) albeit below their respective Indoor Air Method B CULs. Haley& Aldrich is proposing to install an active sub-slab depressurization system (SSDS) to mitigate vapor intrusion from shallow groundwater and sub-slab soil into the indoor air of the adjacent three businesses to the Property. The proposed SSDS will consist of fans/blowers that draw vapors from the soil beneath the buildings through suction pits and discharges the vapors to the atmosphere through a series of pipes. The system will be designed to decrease the air pressure in the soil beneath the building's floor slab. By maintaining a pressure slightly lower than ambient air pressure beneath the buildings, soil vapors are prevented from entering the buildings where they could pose a threat to human health. HgEEN ICH 22 City of Yakima 5 October 2022 Page 3 We are proposing to conduct a SSDS field diagnostic pilot test (pilot test) before the design and installation of the SSDS to aid in the design of the most suitable and cost-effective mitigation strategy, as well as to better quantify the overall magnitude and size of the required mitigation system.The results of the pilot testing will be used to finalize the optimum system layout, SSDS well radius of influence (ROI) and well placement spacing, fan/blower specifications, the number of SSDS suction points/vapor extraction points (VEPs), and fan/blower installation location (i.e., roof/wall mounted vs. a centralized on-ground skid/shed enclosed process equipment) as presented in the preliminary conceptual system design included in this proposal. Preliminary SSDS Conceptual Design The SSDS well placement is based upon the predicted ROI of the SSDS wells that is also referred to as the design basis. The assumed ROI of each VEP is 20 feet, minimum. Based on the on-site and off-site extent and distribution of the constituents of concern(COC)soil vapor concentrations, groundwater impacts, indoor air COC concentration exceedance locations at the three adjoining businesses to the Property, and the assumed SSDS well ROI of 20 feet (equivalent to a center-to-center well spacing design of approximately 35-feet on-center), the preliminary SSDS conceptual design consists of a total of 12 vertical VEP locations. The proposed VEP locations are shown on Figure 3. The assumed vapor extraction ROI will be verified based on the results of the planned SSDS pilot testing, and hence, the system layout, well placement spacing, number of wells, well locations, blower/fan specifications, blower/fan installation location (i.e., roof/wall mounted vs. a centralized on-ground skid/shed enclosed process equipment) proposed herein will be revised accordingly, as needed. The preliminary SSDS conceptual design is presented in Figure 3. The system is proposed to be comprised of 12 exterior VEPs with approximately 35-foot on-center spacing.The extraction points will be constructed of 2-inch polyvinyl chloride (PVC), Schedule 80 riser pipe, with 0.020-inch slot screens from 6 to 11 feet below ground surface (bgs) and include flush-mounted well completion with a traffic rated 3-foot by 2-foot steel well vault, air flow control gate valve, vacuum gauge, and sampling port. Typical VEP construction details are provided in Figure 4.The exterior VEPs will be installed on the west and south sides of the Xochimilco building and on the north and east sides of the building housing the Barber HQ and 1Up Games businesses, as shown in Figure 3. The SSDS will also be comprised of exterior and interior vapor/vacuum monitoring points (VMPs). Each building will have three exterior VMPs. In addition, four interior VMPs are proposed for the Xochimilco Mexican Restaurant, and four interior VMPs are proposed for the Barber HQ and 1Up Games businesses. The proposed VMP locations are shown on Figure 3. Typical VMP well construction details are provided in Figure 4.The exterior VMPs will be constructed of 1-inch PVC, Schedule 40 riser pipe, with 0.020-inch slot screens from 5 to 10 feet bgs and include flush-mounted well completion with a traffic rated 6-inch diameter steel well box.The interior VMPs are proposed to be constructed of two slightly different construction details. Two interior VMPs will be VaporPin® type which are small stainless steel %-inch diameter (or smaller) points. These points will be installed to shallow depths,just below the concrete slab, using a small concrete coring machine and completed with a 1-%-inch stainless steel well cap which will minimize disruptions to the businesses.The other two VMPs will also be installed to shallow depths but will be constructed using a 1-inch-diameter, 2-foot-long PVC Schedule 40 casing and one 1-foot-long HgEEN ICH 23 City of Yakima 5 October 2022 Page 4 PVC Schedule 40, machine-slotted, well screen (0.020-inch slot).These VMPs will be completed within a flush-mounted traffic rated 4-inch diameter steel well box. SSDS wellhead assemblies will be provided within the flush-mounted precast steel well vaults (lockable well box) for each VEP. Wellhead assembly instrumentation and controls (e.g., gate valve, vacuum gauge, and sample port, etc.) will be located with the precast steel vaults. Below grade 4-inch PVC, Schedule 80 conveyance piping (installed in trenches) will connect the VEPs to a centrally located SSDS process equipment shed/container consisting of blower(s), instrumentation, a heat exchanger, and vapor-phase granular activated carbon (VGAC) units.The SSDS process equipment container will be located at the southeastern corner of the former Tiger Oil facility or alternatively the equipment will consist of wall/roof mounted fans/blowers depending upon the equipment sizing to be determined based on the upcoming SSDS pilot test results.The preliminary proposed VEP wellhead locations, below grade conveyance piping layout, and the process equipment container location are shown on Figure 3. The SSDS process equipment will be comprised of regenerative blower(s), a moisture separator, two 500 to 1,000 pounds (Ibs) VGAC units (depending upon the select blower sizing), a heat exchanger, and an exhaust stack that extends above the roof of the SSDS process equipment container.The system will be operated using a Sensa-Phone with Autodialer or a Programmable Logic Controller(PLC) with Remote Telemetry System and Control Panels.A schematic of the proposed SSDS process equipment is provided in Figure 5. Scope of Work We propose to undertake the following services: • Project Kick-Off Meeting, Pilot Test Design, Permitting, Planning, and Coordination • Drilling and Well Installation • Pilot Test Equipment Mobilization and Setup • Pilot Testing • SSDS Design and Implementation Work Plan All field construction and setup work (drilling, well installation, equipment setup, etc.) will be performed under Haley &Aldrich's oversight. All pilot testing activities will be performed by Haley& Aldrich. TASK 1A: PROJECT KICK-OFF MEETING, PILOT TEST DESIGN, PERMITTING, PLANNING,AND COORDINATION Haley&Aldrich proposes a project kick-off meeting with the City of Yakima (the City), Heyden Properties, and Ecology to discuss the task objectives,details,site logistics, and permitting and planning details. HgEEN ICH 24 City of Yakima 5 October 2022 Page 5 Prior to the start of field pilot test activities, the following pilot testing design, permitting, planning, and coordination activities will be performed: 1. Conduct a site reconnaissance to observe the existing conditions and access for performing a pilot test; 2. Evaluate the readily available data relevant to the subsurface soil, groundwater, soil vapor, and indoor air conditions at the Site from geologic maps, boring logs, construction records, and previous environmental investigation and remedial design/implementation reports; 3. Gather readily available information on the building construction, and heating/ventilation/and cooling (HVAC) specifications; 4. Design the pilot test program.The test will involve installation of two exterior VEPs and two exterior VMPs at the west side of the Xochimilco Mexican Restaurant building, and four interior VMPs;and 5. Arrange for special equipment(i.e., rental blower skid with a capacity of approximately 100 standard cubic feet per minute [scfm] air flow rate at approximately6 inches of mercury [in. Hg] vacuum, necessary instrumentation and process monitoring equipment, electrical power generator, two 200 lbs VGAC units for off-gas treatment, etc.) and services required for installation of the extraction and monitoring points, and for performing the pilot test.This includes subcontractor coordination for installation of the extraction and monitoring points, and a geophysical survey to clear the locations of sub-slab obstructions and buried utilities. Prior to the start of field activities, a site-specific Health and Safety Plan (HASP) will be prepared to address potential health and safety concerns for the proposed field activities.The HASP will be prepared in accordance with the requirements of the Washington State Department of Labor and Industries, Division of Occupational Safety and Health (DOSH), Washington Industrial Safety and Health Act (WISHA) and the United States Occupational Health and Safety Administration 29 Code of Federal Regulations 1910.120, Hazardous Waste Operations and Emergency Response. The proposed SSDS pilot test rental equipment includes active process equipment components (e.g., blower) and VGAC units for the treatment of extracted soil vapors, and therefore will need to be authorized by the Yakima Regional Clean Air Agency prior to construction, setup, and initiation of the pilot test startup and operational activities. Accordingly, an air emissions discharge permit will be acquired and/or notification to the Yakima Regional Clean Air Agency will be performed, as applicable, prior to initiation of any field activities at the Site. Haley&Aldrich's drilling contractor will mark each of the planned pilot test VEP and VMP installation location at the Site and notify the underground utility service alert(i.e., Washington Utility Notification Center Call in at 811) prior to the start of drilling activities. Each boring location will also be screened and cleared for utilities by a private utility locator and if necessary, cleared by manual excavation and/or air- vacuumed to a depth of approximately 3 feet bgs as a final check for potential presence of underground utilities. HgEEN ICH 25 City of Yakima 5 October 2022 Page 6 As previously presented, the pilot test will involve installation of two exterior VEPs and two exterior VMPs at the west side of the Xochimilco Mexican Restaurant building, on the Property, and four interior VMPs within the Xochimilco Mexican Restaurant building. Furthermore, the proposed pilot test rental process equipment(i.e., blower skid, VGAC units, rental generator, etc.) is planned to be temporarily located near the eastern property boundary of the Property. Prior to initiation of any fieldwork, written authorization from Heyden Properties, Xochimilco, Barber HQ, and 1Up Games owners and/or tenants will be obtained for the installation of temporary pilot test infrastructure (wells and equipment, etc.) and for the day-to-day field activities to be performed at their respective properties as part of the pilot test. All field activities will be coordinated with Heyden Properties, the City, and Ecology Site Manager, Xochimilco, Barber HQ, and 1Up Games. Haley&Aldrich will be in direct communications with the City and Ecology throughout all field activities. This task is estimated to be completed in approximately 2-3 weeks from project authorization. TASK 1B: DRILLING AND WELL INSTALLATION A total of two exterior VEPs (VEP-1 and VEP-2), two exterior VMPs (VMP-1 and VMP-2), and four interior VMPs (VMP-3 through VMP-6) will be installed for the pilot test. The VEPs will be placed at locations that attempt to approximate the performance of an active SSDS.The interior VMPs will be placed radially to evaluate vacuum propagation beneath the Xochimilco building slab.The proposed SSDS pilot test well locations are depicted on Figure 6.This pilot test extraction and monitoring point network will also be utilized for and integrated into the full-scale SSDS design.The VEPs will be screened from approximately 6 to 11 feet bgs and the VMPs will be screened from approximately 5 to 10 feet bgs. Typical well construction details are shown on Figure 4.The final well depths and locations will be adjusted and determined during well installation activities based on the field conditions.The proposed VEPs and VMPs will be installed as follows: • For the VEPs, limited identification of specific soil intervals will be performed from 0 to 12 feet bgs. Continuous soil cores will be collected using a split spoon sampler (or equivalent). Soil cores will be examined visually for geological characteristics and logged, by a Haley&Aldrich geologist. A dual use direct push & hollow-stem auger drilling unit (truck or track mounted) will be used to first advance a 2.25-inch diameter boring to 12 feet for soil logging purposes,then ream the boring with 6-inch or 8-inch diameter augers to construct the VEP. • The VEPs will be constructed using a 2-inch-diameter, PVC Schedule 80 casing and one 5-foot-long PVC Schedule 80, machine-slotted, well screen (0.020-inch slot) with # 2 filter pack sand placed from the bottom of the boring to approximately six inches above the top of each screen interval (Figure 4). VEPs will be screened at approximately 6 to 11 feet bgs. • Six inches of dry granular bentonite, and two feet of hydrated bentonite chips or pellets will be placed above the upper filter pack interval to form a transition seal.Cement-bentonite grout will be placed above the transition seal to ground surface. • All VEP casing risers will be sealed with a 3-feet diameter geomembrane/well borehole seal near the surface completion location at approximately 2 to 3 feet bgs. HgEEN ICH 26 City of Yakima 5 October 2022 Page 7 • All VEPS will be completed with an 8-inch flush-mounted traffic rated cover/well box. • For each VEP, an air-water tight well casing cap (with a lockable plug) will be installed at the top of well casing within the well box. Wellhead controls for the pilot test including a sample port, a vacuum gauge, and a gate valve will be installed on an above ground manifold that will be connected to the top of well casing within the well vault. • The exterior VMPs will be installed using direct push drilling technology to an approximate depth of 11 feet bgs. • The exterior VMPs will be constructed using a 1-inch-diameter, PVC Schedule 40 casing and one 5-foot-long PVC Schedule 40, machine-slotted, well screen (0.020-inch slot) with # 2 filter pack sand placed from the bottom of the boring to approximately six inches above the top of each screen interval (Figure 4). The exterior VMPs will be screened at approximately 5 to 10 feet bgs. • Six inches of dry granular bentonite, and two feet of hydrated bentonite chips or pellets will be placed above the upper filter pack interval to form a transition seal.Cement-bentonite grout will be placed above the transition seal to ground surface. • All exterior VMPs will be completed with a 6-inch flush-mounted traffic rated cover/well box. • For each VMP, an air-water tight well casing cap (with a lockable plug) and a sample port will be installed at the top of well casing within the well box. • The interior VMPs are proposed to be constructed of two slightly different construction details. Two interior VMPs (VMP-3 and 6) will be VaporPin® type which are small stainless steel %-inch diameter(or smaller) points.These points will be installed to shallow depths, just below the concrete slab, using a small concrete coring machine and completed with a 1-%-inch stainless steel well cap which will minimize disruptions to the businesses.The other two VMPs (VMP-4 and VMP-5) will also be installed to shallow depths but will be constructed using a 1-inch- diameter, 2-foot-long PVC Schedule 40 casing and one 1-foot-long PVC Schedule 40, machine- slotted, well screen (0.020-inch slot) with #2 filter pack sand placed from the bottom of the boring to approximately six inches above the top of the screen interval. These VMPs will be completed within a flush-mounted traffic rated 4-inch diameter steel well box. All drilling and well installation work shall be performed by a Washington licensed driller who will be a subcontractor to Haley & Aldrich. All drilling and well installation work will be performed under Haley & Aldrich's oversight. The location of the VEPs and VMPs will be surveyed and reported as longitude and latitude relative to North American Datum of 1983.The ground surface and top-of-casing elevation will be surveyed relative to North American Vertical Datum of 1988. Investigation-derived-waste (IDW) generated during drilling and well installation activities such as equipment wash, and rinse water and soil cuttings will be placed into 55-gallon Department of Transportation approved drums and temporarily stored on Site. The waste will be characterized and disposed of within approximately 90 days once the characterization of the IDW has been completed and approved by the regulated disposal facility. This task is estimated to be completed in approximately 3 to 4 fieldwork days. HgEEN ICH 27 City of Yakima 5 October 2022 Page 8 TASK 1C: PILOT TEST EQUIPMENT MOBILIZATION AND SETUP Rental process equipment, skid mounted, or a temporary container/shed/trailer mounted, meeting the design specifications as provided in this section will be used at the Site for pilot testing.The rental process equipment will be equipped with the capacity to extract vapors at approximately 100 scfm at an applied vacuum of approximately 6 in. Hg or 68 in. H2O vacuum at the inlet of the blower skid.The rental process equipment will primarily consist of: • A regenerative blower (or approved equivalent), with variable frequency drives (VFDs), with an air flow rate capacity of approximately 100 scfm at approximately 6 in. Hg or 68 in. H2O vacuum measured at the inlet of the blower; • One dilution air valve; • One inline particulate filter; • One 60 gallons capacity air moisture separator with demister; • One water/condensate transfer pump rated for 10 gallons per minute flow capacity at a total discharge pressure head capacity of 50 feet; • Two 200 lbs VGAC units (depending upon the select blower sizing), installed in series, to be sized by the equipment supplier based on the SSDS design total air flow rate and anticipated low levels of vapor concentrations in the system influent; • A heat exchanger, if needed based upon the selected blowers air discharge temperature; • Silencers, if needed, based on noise generated by the blower; • One 10 feet tall air discharge stack constructed of a 4-inches diameter PVC Schedule 40 solid pipe with supports; and • Valves, instrumentation, and controls, as required. The rental process equipment, instrumentation, and wiring associated with the enclosure will be constructed to Class I, Division II Standards as per National Fire Protection Association (NFPA) National Electric Code (NEC) standards (e.g., NFPA 70 and NFPA 496) and Underwriter Laboratories (UL 1604) standards. Automatic controls will be provided to protect the process equipment. Process gauges/indicators will be provided as required to monitor the performance of the system.The main control panel for the rental equipment will be located inside of the preassembled enclosure and will be constructed to National Electrical Manufacturer Association (NEMA)4X standards. The rental process equipment will be delivered and setup at the Site by the equipment supplier. All equipment will be temporarily placed near the eastern property boundary of the Property (Figure 6).A temporary chain-linked fence (approximately 60 linear feet) will be built around the rental equipment with access gates.The rental equipment will be powered by a tow-behind, appropriately sized, rental diesel/gasoline electrical generator. The connection of the rental process equipment main power disconnect to the electrical generator will be provided by a Washington licensed electrician or a trained professional from the equipment supplier company.The trained professional from the equipment supplier company may also assist in performing the process HgEEN ICH 28 City of Yakima 5 October 2022 Page 9 equipment shakedown/startup to check the proper functionality of all components of the equipment prior to initiating the SSDS pilot testing. This task is estimated to be completed in approximately one to two fieldwork days. TASK 1D: PILOT TESTING The SSDS pilot test will be conducted for approximately two to three days at extraction well VEP-1. The extraction well will be fitted with an above ground manifold containing wellhead controls including a sample port, a vacuum gauge, and a gate valve. A total of three vacuum-air flow rate conditions will be tested at the extraction well. Initially, a low vacuum will be applied at the extraction wellhead (less than 2 in. Hg). The vacuum will then be increased to the full capacity of the blower (i.e., 6 in. Hg).The vacuum will then be gradually decreased to reach an approximate mid-point (i.e., 4 in. Hg) while measuring the resultant air flow rates at the extraction well at all the three vacuum-air flow rate conditions. The extraction air flow rates at the extraction well will be measured using a Pilot Tube® or a Thermal Anemometer/Mass Flow Meter.The other extraction well,VEP-2, exterior VMPs (VMP-1 and VMP-2),and interior VMPs (VMP-3 through VMP-6) will be used as observation points to collect vacuum influence/propagation data (Figure 6). Any groundwater and entrained moisture extracted from VEP-1 will be transferred to 55-gallon holding tank(s) for characterization and off-site disposal.The extracted soil vapor will be treated via two 200 lbs VGAC units in series under the Yakima Regional Clean Air Agency permit/authorization. The observation points used for vacuum observation will be covered with a plastic cap fitted with al/4- inch valve and barbed fitting.The caps will create a tight seal around the well and not allow the vacuum to escape. Vacuum at the extraction well and observation points will be measured using a hand-held Digital Manometer/Magnehelic Differential Pressure Gauges connected to the barbed fittings. Water levels in the wells, if present, will be measured using a manual electronic sounder. Baseline Data The following baseline information will be collected and recorded. • Depth-to-water (DTW) measurements in the observation wells (VEP-2, VMP-1, VMP-2, VMP-4, and VMP-5) and the extraction well (VEP-1)— Note that the DTW cannot be taken at VMP-3 and VMP-6 since these points are VaporPin®Type; • Vacuum from the observation wells (VEP-2, and VMP-1 through VMP-6); • Hour meter reading at the process equipment unit; and • Totalizer readings at the process equipment unit. A vapor sample will be collected (in a summa canister) from the extraction well (VEP-1) casings and analyzed using U.S. Environmental Protection Agency (EPA) Method TO-15 for VOCs, and gasoline-range- TPH. In addition, wellheads of all the observation points will be monitored with a hand-held photo ionization detector (PID) during the prior to start of the pilot test extraction activities. HgEEN ICH 29 City of Yakima 5 October 2022 Page 10 Operational Field Data The following data will be collected and recorded during the testing. • Data at the rental process equipment — System vacuum (in. Hg or in. H20); — System air flow rate (scfm); — Daily influent and effluent vapor concentrations via PID (parts per million by volume) and via sampling using summa canisters for laboratory analysis using EPA Method TO-15 for VOCs and gasoline-range TPH; — System hour meter (hour); — Blower temperature (degrees Fahrenheit); — Water/condensate knock-out (KO) pot totalizer(gallons); — Hourly transfer rate of water from KO pot to Storage Tanks (gallons per hour); — Blower hertz; — Dilution air valve position; • Data at Extraction Well — DTW below top of well casing (feet);and — Air flow rate at wellhead; — Vacuum at wellhead (in. Hg or in. H20);and — Final (before completion of the pilot test) VEP-1 vapor concentration via PID (parts per million by volume) and via sampling using summa canisters for laboratory analysis using EPA Method TO-15 for VOCs and gasoline-range TPH. • Data at Observation Wells — Well head vacuum (in. H20); — DTW below top of well casing (feet) with manual measurements; and — Final (before completion of the pilot test)vapor concentrations at the observation wells via PID (parts per million by volume ). Select vapor samples from some of the observation wells may also be collected in summa canisters for laboratory analysis using EPA Method TO-15 for VOCs and gasoline-range TPH. For each vacuum-air flow rate condition, a minimum of three full sets of aforementioned data/readings will be collected after reaching vacuum equilibrium/stabilization conditions.The frequency may be modified during the test based on field observations. Following completion of the test, all extraction and observation wells will be left in place and the risers will be capped.The extraction and observation wells may be incorporated into the full-scale SSDS design, assuming the resulting data support this approach. HgEEN ICH 30 City of Yakima 5 October 2022 Page 11 Following completion of the pilot test, the rental equipment, temporary manifold, and temporary chain- linked fence will be disassembled and demobilized from the Site. This task is estimated to be completed over three fieldwork days to perform the pilot test and a half fieldwork day to disassemble the pilot testing manifold, equipment, and chain-linked fence. TASK 1E: SSDS DESIGN AND IMPLEMENTATION WORK PLAN Haley&Aldrich will evaluate the pilot test data and perform engineering calculations and computational 2D pneumatic modelling to select the appropriate remedial approach, and to support a preliminary system design. Based on the evaluation, the preliminary SSDS design as included in this proposal will be revised, as needed, and the design will be finalized.The final SSDS design will include the system layout, and process equipment needed for effective capture of sub-slab vapors and adequate vacuum propagation underneath the buildings slab.We will identify the optimal layout for SSDS extraction points, piping, process equipment (e.g., extraction fans/blowers and discharge manifold), and permanent sub-slab sampling ports. The proposed system will be designed to minimize disruptions to future operations at the Property's constructed building(s) and to achieve the objective of reducing concentrations of COCs in the indoor air. Depending on the results of the evaluation, the design may include installation of perforated/slotted horizontal pipe network(horizontal wells) to achieve adequate coverage across the treatment area. Piping may be routed externally, or within the site building, for discharge above the roofline. The design may involve multiple roof/wall mounted extraction fans/blowers or a centralized on-ground skid/shed enclosed process equipment.The design may also incorporate secondary elements to improve system performance, such as air inlet wells, or sealing the buildings slab with a product designed to reduce vapor intrusion (e.g., Retro Coati") An implementation work plan for the construction, startup, and initial operation, maintenance, and monitoring (OM&M) of the SSDS at the Xochimilco and Barber HQ and 1Up Games buildings will also be prepared during this task. In addition, a planning level engineer's cost estimate for the construction, startup, and initial OM&M of the SSDS will be prepared. The pilot test findings, final SSDS design, SSDS implementation work plan, and the planning level engineer's cost estimate for SSDS implementation will be provided to the City and Ecology in a technical memorandum which will be signed and stamped by a qualified professional engineer(PE) licensed in the state of Washington. At a minimum, this document will include: a. Presentation of the pilot test findings and associated engineering calculations and pneumatic modelling; b. A schematic of the proposed full-scale SSDS and equipment; c. Identification of location for the proposed SSDS extraction and monitoring points; d. System and process equipment general arrangement and layout; e. Subsurface piping details; HgEEN ICH 31 City of Yakima 5 October 2022 Page 12 f. System process and instrumentation diagram (P&ID); g. System general control logic; h. System typical construction details; i. A list of required permits for construction and operation of the proposed SSDS; j. Implementation work plan for the construction, startup, and initial OM&M of the SSDS; and k. Planning level engineer's cost estimate for the construction, startup, and initial OM&M of the SSDS. This task is estimated to be completed in approximately S to 12 weeks from conclusion of the pilot test, and receipt of all requested documents including previous environmental reports, architectural and construction details for the Property's anticipated future building construction (as applicable), and HVAC specifications. The scope of services does not include the following items: 1. Abandonment of the pilot test extraction points if the evaluation indicates that these locations are not suitable for a SSDS, or if the Property owner decides to forego implementation of the system. 2. Design services and deliverables beyond production of the design memorandum described in Task 1E. Design modifications or additions may be required to make it"construction ready." For example, these may result from the Ecology requests following their review of the SSDS design and implementation work plan. Furthermore, the results of the pilot test may indicate that a remedial solution consisting solely of a SSDS will not be effective for achieving the required reduction of indoor air contaminants. In this case, pursuit of alternative remedial solutions such as HVAC modifications to create a positive-pressure environment within the site buildings may be required;the assessment of such alternative remedial solutions is not included in the scope of this proposal. 3. Also excluded under this clause are any structural design elements that may be required for installation of a proposed SSDS system. For example, installation of the proposed SSDS may require structural calculations to determine if the roof can support the loads required for placement of the extraction fans)/blowers and manifold. 4. Implementation of the proposed design.This includes solicitation of environmental construction firms, system construction, air discharge permitting, overseeing construction activities, or preparation of a construction completion report for submission to the City and Ecology. 5. Haley&Aldrich provides no guarantees that the proposed remedial design, if implemented, will be sufficient to reduce the concentrations of indoor air contamination below the applicable regulatory standards that may be required as a condition of regulatory closure for the Site. HgEEN ICH 32 City of Yakima 5 October 2022 Page 13 These aforementioned excluded services can be provided under the terms of a different agreement, if acceptable to both parties. We request that the following items be provided to us: • Available data relevant to the subsurface soil, groundwater, soil-vapor, and indoor air conditions at the Site from geologic maps, boring logs, construction records, and previous environmental investigation and remedial design/implementation reports;and • All available documents and specifications pertaining to future planned Site buildings construction, as available and applicable. These documents may include structural diagrams, floor plans, architectural drawings, and specifications for the building HVAC system.
