YAKIMA, WASHINGTON
AGENDASTATEMENT
Item No. 16.
For Meeting of: December 6, 2016
ITEM TITLE: Ordinance amending Chapter 7.60 of the Yakima Municipal Code
regarding Wastewater Collection and Treatment Rates and
Charges
SUBMITTED BY: Scott Schafer, Director of Public Works
Mike Price, Wastewater/Stormwater Manager - 249-6815
SUMMARY EXPLANATION:
The City is authorized by Title 35 RCW to acquire, construct, own, operate, and provide financing
for waterworks and systems of sewerage, and to establish rates, fees, and charges for that
service. In accord with that authority, the City assesses wastewater collection and treatment rates
and charges as established in §7.60 of the YMC.
To maintain pace with all of the regulatory compliance and aging infrastructure replacement
needs identified over the next ten years, wastewater rates ultimately need to be
increased. Should rates not be increased, the only alternative would be to significantly increase
the Division's debt service; reducing its available cash and cash transfers in order to meet
regulatory mandates.
In order to provide an unbiased comprehensive analysis of the Wastewater Division's financial
needs, the City contracted with FCS Group to conduct a rate study over a ten-year period (2012-
2021). Such services provide the City with an objective in-depth look as to what proper funding
levels are really required to ensure the citizens of Yakima with wastewater services now, and in
the future; while remaining compliant with all of the federal and state rules and regulations.
FCS Group's ten-year review of the Wastewater Division's maintenance program, capital needs,
and regulatory requirements for both the WWTP and the sanitary sewer collection system
identified the need to eliminate the $220,000 annual subsidy of the Pretreatment Program
currently being provided from wastewater user rates. Based on regulatory requirements,
replacement costs, and current funding levels, FCS Group has also proposed an annual rate
increase of approximately 3% for the next two years to provide the Wastewater Division with
proper funding levels.
The proposed rates substantially remove the Pretreatment customer subsidy by increasing (18%
in each of 2017 and 2018) the monthly Pretreatment charge for commercial customers enrolled
in the Pretreatment Program. The proposed retail base rate and the retail volume rate increase is
3% per year through 2018. A modified rate structure is proposed for industrial wastewater that is
discharged to the industrial waste line (IW line) and treated in the upflow anaerobic sludge blanket
digester (UASB) that was brought online in 2013. The modified rate structure more accurately
reflects the cost of service for service IW line/UASB customers.

(c) Minimum Charge. In no event shall the total wastewater service charge
be less than the ready -to -serve charge for a 3/4" meter, except that customers
beginning or ending wastewater service shall have the ready -to -serve charge
pro -rated to their number of days of service during the billing period.
(2) Wastewater Service Charge for Outside -City Customers. Minimum, Rready-to-serve, and
volume charges to premises located outside the City shall be 1.50 times the inside -City rates set
forth in Section 7.60.020 (A)(1).
B. Strong Waste Surcharge. For customersthe ty discharging wastewater
which contains more than three hundred parts per million (ppm) of biochemical oxygen demand
(BOD) and/or total suspended solids and (TSS) and/or one hundred parts per million of fats,
oils, greases (FOG), there shall be a surcharge, in addition to the ready -to -serve charge and the
volume charge, which shall be calculated utilizing the national average values of BOD and TSS
concentrations typical to each classification under the Standard Industrial Code or by actual
concentrations verified by the city. If the customer chooses, at its expense, to install a sampling
station, the strong waste charge shall be calculated based upon actual concentrations. Any
testing done by the city may be charged at the rates set forth in YMC 7.60.105. The following
formula shall be utilized to calculate the strong waste surcharge:
Monthly surcharge for BOD or TSS or FOG = (unit cost per pound of BOD or TSS or FOG)
times (8.34, which iso the weight of one gallon of water) times (customer's monthly volume in
one hundred cubic feet divided by one thousand three hundred thirty-seven) times (customer's
concentration of BOD or TSS or FOG in parts per million according to_ [the national average
values] or [verified concentrations], minus the domestic strength threshold in parts per million
three hi in`Jrod but not less than zero). The separate monthly surcharges for BOD, TSS, and
FOG shall be summed together to create the strong waste surcharge.
In the foregoing formula, the applicable values are as follows:

Hypothetical example: In a given month, a customer discharges 50 ccf of wastewater measured
with BOD of 400 ppm, TSS of 350 ppm, and FOG of 80 ppm. This customer is not charged a
FOG surcharge because the customer's measured FOG is below the domestic threshold.
Assume a unit cost per pound of $0.5680 for BOD and $0.5266 for TSS. The strong waste
surcharge for the given month is calculated as follows:
BOD surcharge: $0.5680/pound x 8.34 x (50 ccf _ 1,337) x (400 ppm - 300 ppm) _
17.72
TSS surcharge: $0.5266/pound x 8.34 x (50 ccf _ 1,337) x (350 ppm - 300 ppm) _ $8.21
Total strong waste surcharge: $17.72 + $8.21 = $25.93
Section "3. Section 7.60.025 of Chapter 7�C-Is the Yakima Municipal Code is
hereby amended to read as follows:
7.60.025 Charges to industrial wastewater customers.
A. In lieu of the regular rates set forth in Section 7.60.020, industrial wastewater customers
shall be charged the industrial wastewater charge, wastewater service charge and strong waste
surcharge set forth in the following Section 7.60.025(B), except that the total charged to a given
industrial wastewater customer in a given year pursuant to the Section 7.60.025(B) shall not
exceed the amount that would have been charged to that same industrial wastewater customer
under the regular rates set forth in Section 7.60.020.
B. Industrial Wastewater Charge, Wastewater Service Charges and Strong Waste Surcharge
for Industrial Wastewater Customers.
(1) Industrial Wastewater Charge. Industrial wastewater customers shall be charged the
following amounts per hundred cubic feet (ccf) of flow discharged into the industrial wastewater
sewer line.

(2) Wastewater Service Charges for Industrial Wastewater Customers. Industrial wastewater
customers shall be charged 60% of the regular ready -to -serve and volume charges set forth in
Section 7.60.020.
(3) Strong Waste Surcharges for Industrial Wastewater Customers. Industrial wastewater
customers shall be charged the regular strong waste surcharges set forth in Section
7.60.020(B), provided that the BOD surcharge for an industrial wastewater customer shall be
calculated based on the adjusted BOD concentration, which means the measured BOD
concentration multiplied by the BOD adjustment percentage.
C. If a given property discharges into both the industrial wastewater line and the regular sewer
system, the regular rates set forth in 7.60.020 apply to the effluent discharged into the regular
sewer system. If a given property discharges wastewater to the industrial wastewater line that
is harmful to the UASB treatment process or wastewater that is not amenable to the UASB
treatment process as determined by the Wastewater Division manager, thereby requiring that
the wastewater bypass the UASB treatment process, the regular rates set forth in 7.60.020
apply to the wastewater.

7.60.020 Retail wastewater servicecharge c r .
A. Wastewater Service Charge. There shall be charged to and collected from all premises
within the city served by the city wastewater system a wastewater service charge composed of
a monthly ready -to -serve charge and a volume charge based on either the quantity of water
supplied to the premises or, if metered, the quantity of wastewater discharged into the
wastewater sewer system. In addition, a strong waste surcharge shall be charged to and
collected from all premises served by the City wastewater system that discharge wastewater
exceeding the domestic strength thresholds set forth in Section 7.60.020(B) below; provided,
that in no event shall the total wastewater service charge be less than the minimum charge
indicated below:

(c) Minimum Charge. In no event shall the total wastewater service charge
be less than the ready -to -serve charge for a 3/4" meter, except that customers
beginning or ending wastewater service shall have the ready -to -serve charge
pro -rated to their number of days of service during the billing period.
(2) Wastewater Service Charge for Outside -City Customers. Minimum, ready -to -serve, and
volume charges to premises located outside the City shall be 1.50 times the inside -City rates set
forth in Section 7.60.020 (A)(1).
B. Strong Waste Surcharge. For customers discharging wastewater which contains more than
three hundred parts per million (ppm) of biochemical oxygen demand (BOD) and/or total
suspended solids and (TSS) and/or one hundred parts per million of fats, oils, greases (FOG),
there shall be a surcharge, in addition to the ready -to -serve charge and the volume charge,
which shall be calculated utilizing the national average values of BOD and TSS concentrations
typical to each classification under the Standard Industrial Code or by actual concentrations
verified by the city. If the customer chooses, at its expense, to install a sampling station, the
strong waste charge shall be calculated based upon actual concentrations. Any testing done by
the city may be charged at the rates set forth in YMC 7.60.105. The following formula shall be
utilized to calculate the strong waste surcharge:
Monthly surcharge for BOD or TSS or FOG = (unit cost per pound of BOD or TSS or FOG)
times (8.34, which is the weight of one gallon of water) times (customer's monthly volume in one
hundred cubic feet divided by one thousand three hundred thirty-seven) times (customer's
concentration of BOD or TSS or FOG in parts per million according to [the national average
values] or [verified concentrations], minus the domestic strength threshold in parts per million,
but not less than zero). The separate monthly surcharges for BOD, TSS, and FOG shall be
summed together to create the strong waste surcharge.
In the foregoing formula, the applicable values are as follows:
Unit Cost per Pound
Domestic
Strength
Threshold
Effective
January
8, 2017
Effective
January
1, 2018
BOD
300 ppm
$0.5680
$0.5900
TSS
300 ppm
$0.5266
$0.5470
FOG
100 ppm
$0.3729
$0.3836
Hypothetical example: In a given month, a customer discharges 50 ccf of wastewater measured
with BOD of 400 ppm, TSS of 350 ppm, and FOG of 80 ppm. This customer is not charged a
FOG surcharge because the customer's measured FOG is below the domestic threshold.
Assume a unit cost per pound of $0.5680 for BOD and $0.5266 for TSS. The strong waste
surcharge for the given month is calculated as follows:
BOD surcharge: $0.5680/pound x 8.34 x (50 ccf _ 1,337) x (400 ppm - 300 ppm) _
$17.72
TSS surcharge: $0.5266/pound x 8.34 x (50 ccf _ 1,337) x (350 ppm - 300 ppm) _ $8.21
Total strong waste surcharge: $17.72 + $8.21 = $25.93
Section 3. Section 7.60.025 of the Yakima Municipal Code is hereby amended to read as
follows:
A. In lieu of the regular rates set forth in Section 7.60.020, industrial wastewater customers
shall be charged the industrial wastewater charge, wastewater service charge and strong waste
surcharge set forth in the following Section 7.60.025(B), except that the total charged to a given
industrial wastewater customer in a given year pursuant to the Section 7.60.025(B) shall not
exceed the amount that would have been charged to that same industrial wastewater customer
under the regular rates set forth in Section 7.60.020.
B. Industrial Wastewater Charge, Wastewater Service Charges and Strong Waste Surcharge
for Industrial Wastewater Customers.
(1) Industrial Wastewater Charge. Industrial wastewater customers shall be charged the
following amounts per hundred cubic feet (ccf) of flow discharged into the industrial wastewater
sewer line.
Effective Date
Industrial Wastewater Rate
January 8, 2017
$7.69 per ccf
January 1, 2018
$7.77 per ccf
(2) Wastewater Service Charges for Industrial Wastewater Customers. Industrial wastewater
customers shall be charged 60% of the regular ready -to -serve and volume charges set forth in
Section 7.60.020.
(3) Strong Waste Surcharges for Industrial Wastewater Customers. Industrial wastewater
customers shall be charged the regular strong waste surcharges set forth in Section
7.60.020(B), provided that the BOD surcharge for an industrial wastewater customer shall be
calculated based on the adjusted BOD concentration, which means the measured BOD
concentration multiplied by the BOD adjustment percentage.
C. If a given property discharges into both the industrial wastewater line and the regular sewer
system, the regular rates set forth in 7.60.020 apply to the effluent discharged into the regular
sewer system. If a given property discharges wastewater to the industrial wastewater line that
is harmful to the UASB treatment process or wastewater that is not amenable to the UASB
treatment process as determined by the Wastewater Division manager, thereby requiring that
the wastewater bypass the UASB treatment process, the regular rates set forth in 7.60.020
apply to the wastewater.
Section Section 7.60.035 of the Yakima Municipal Code is hereby amended to read a
follows:
A. Septage Wastewater Disposal Charge. For septage wastewater disposed pursuant to
Chapter 7.53, the following charge shall apply:
Charge Effective January 8,
2017
Charge Effective January 8,
2017
$0.4459/gallon
B. Exceptional Wastewater Disposal Charge. For exceptional wastewater disposed pursuant
to Chapter 7.03, the charge shall be calculated by reference to the following formula:
Exceptional Wastewater Charge = (Treatment Costs) + (Receiving Costs) + (Testing Costs)
(1) Treatment Costs. Treatment costs shall be determined by reference to the
following formula:
Treatment Costs = [(UBOD/TSS) x (WW) x (V/1,337) x (CBOD/TSS)] + [(Uv) x (V)] where:
V = Volume discharged (in one hundred cubic feet);
CBOD/TSS = Concentration of BOD or TSS (in parts per million); and the remaining values are as
follows:
(2) Receiving Costs. Receiving costs shall be calculated by the wastewater
manager and based on actual or estimated staff time, materials, and related costs
incurred in connection with receiving the particular waste at issue.
(3) Testing Cost. The costs of any testing are set forth in YMC 7.00.100. The
wastewater manager shall have final authority over what tests shall be required for
any discharge.
