(A) Consumption base rate, including excess sewage: $57.21 per 1,000 cubic feet.
(B) Annual fixed user charges: $71.30
(C) RV annual fixed construction charges: $17.51.
(D) Sewage disposal rates outside the city. Charges for sewage disposal service to premises outside the city shall be 100% of the rates and charges set forth in divisions (A) and (B) above or as may hereafter be established for sewage disposal service by City Council resolution.
(E) Industrial Waste Control (IWC) charge. All non-residential users shall pay an IWC charge based on meter size. This is a flat rate without regard to consumption. Rates shall be based on meter size as prescribed by the wholesale supplier.
(F) Industrial waste surcharge. Commercial and industrial users who discharge wastes into the public wastewater system in excess of the strength of normal sewage shall be charged a surcharge which reflects their equitable share of the costs of wastewater treatment. The surcharge shall be determined as follows.
(1) Purpose and objective. This section has as its purpose the protection of public health and safety, and because of the widely varying quality characteristics of the sewage discharged by different users of the public sewer and the publicly-owned treatment works, it is the objective of this section to impose sewage charges which reflect the cost of treating sewage strength factors as well as sewage volume. These charges to commercial and industrial users will be in the form of a payment called a surcharge and will reflect industries equitable costs of wastewater treatment in excess of the strength of the domestic sewage. Sewage charge will be based on a volume rate and surcharge based on volume of discharge and the strength of BOD, suspended solid, phosphorous, fats, oil and grease or other pollutants present in the wastewater. In the event other pollutants are required to be surcharged under this subchapter, authorized variances, or by special arrangements with the owner of the publicly-owned treatment works, the rules and regulations adopted herein will apply, the rules and regulations being on file with the City Clerk.
(2) Authority. This section is adopted pursuant to and in accordance with the requirements of Federal Law Clean Water Act, 33 USC 1231 et seq. and applicable Federal Regulations, the requirements of the Settlement Agreement in U.S. v City of Detroit, et al, Civil Action #7-71111.
(3) Industrial waste pollutant strength surcharges. It is ordained that the Schedule of Industrial Waste Pollutant Strength Surcharges is hereby adopted and made effective for users of the wastewater system of the city. The surcharges are to be computed as follows.
Computation of Industrial Waste Pollutant Strength Surcharge
The industrial waste pollutant strength surcharge shall be computed in accordance with the following formula.
SC = 0.0624 V a(BOD-275) + b(TSS-350)+c(P-12)+d(FOG-100)
In which the following apply.
SC = Pollutant strength surcharge fee in dollars for the billing period in Mcf (1000 cubic feet).
V = Volume of waste discharged in the billing period in Mcf (1000 cubic feet).
BOD = Five-day biochemical oxygen demand of the waste expressed in milligrams per liter (ppm).
TSS = Total suspended solids in the waste expressed in milligrams per liter (ppm).
P = Phosphorus in the waste expressed in milligrams per liter (ppm).
FOG = Fats, oils, and grease expressed in milligrams per liter (ppm).
a, b, c, d = Surcharge rates, $/pound for treating BOD, TSS, P, and FOG respectively.
0.0624 = Factor which converts Mcf to MM lbs.
a = $.254.285/pound.
b = $324.341/pound.
c = $3.7293.862/pound.
d = $.221/2.55/pound.
(4) Compliance required. In accordance with the basic service agreement between the city, the county, and the Wayne County Board of Public Works or other properly designated agent of the county named pursuant to M.C.L.A. §§ 46.171 through 46.185, and M.C.L.A. §§ 123.71 et seq., this section provides that any person, firm, or corporation discharging wastewater into the publicly-owned sewer system shall comply with the standards, rules and regulations controlling the quality or quantity of discharge or wastewater into the system. The standards, rules, and regulations shall be established from time to time by the county or its designated agent.
