(A) Pursuant to the provisions of this section, the following schedule of rates and charges is hereby imposed upon users:
(1) Flow processing fees. The city shall impose monthly fees for the processing of wastewater discharged to the POTW. These fees shall be calculated by determining the total quantity of flow discharged to the POTW during the monthly billing cycle and assessing a fee at the indicated rate per 1,000 gallons discharged. In cases where no meters are available to determine the quantity of flow discharged, the fee indicated in division (A)(1)(e) shall be assessed until an appropriate metered value can be obtained.
(a) Class 1.
1. Residential flow processing rate (per 100 gallons): $0.858.
2. Commercial flow processing rate (per 100 gallons): $0.858.
(b) Class 2. Industrial flow processing rate (per 100 gallons): $0.536.
(c) Class 3. Government flow processing rate (per 100 gallons): $0.955.
(d) Class 4. K-12 public schools flow processing rate (per 100 gallons): $0.803.
(e) Minimum monthly fees for metered facilities.

(f) Minimum monthly fees for unmetered facilities.
1. Wells, residential and commercial: $51.72.
2. Other: $72.93.
(2) Surcharge for high strength wastewater. Any user that discharges high strength wastewater to the POTW shall be assessed surcharges in accordance with the requirements of this section.
(a) The city reserves the authority to prohibit the discharge of high strength wastewaters to the POTW when such wastewaters will cause or are reasonably expected to cause overloading, damage, upset or interference in the POTW.
(b) The assessment of surcharges to cover the additional expense of treating high strength wastewaters discharged to the POTW shall not be construed as acceptance of high strength wastewaters for treatment by the city.
(c) The city, at its sole discretion, may assess surcharges for high strength wastewater containing excessive oxygen demanding pollutants by using the applicable rates for cBOD5 or COD; but may not assess surcharges using both pollutant measures.
(d) In cases where a user discharges wastewater having a concentration of cBOD5, COD, TSS or Ammonia-N which exceeds a discharge limitation established in accordance with § 55.019; the user will be subject to an assessment of applicable surcharges for high strength wastewater as provided in this section, as well as an appropriate enforcement action as provided by §§ 55.240 through 55.247, §§ 55.255 through 55.258, and §§ 55.290 through 55.292 and the city’s enforcement response plan.
(e) The city may require the user to conduct self-monitoring to measure and determine the strength and character of all wastewater, sewage and other wastes discharged to the POTW; in such manner and by such method as the city may deem practicable in the light of the conditions and attending circumstances; in order to determine an appropriate surcharge for a given monthly billing cycle.
(f) The city reserves the right to obtain samples of wastewater, sewage and other wastes discharged to the POTW for the purpose of determining the character and strength of a user’s discharge and to determine an appropriate surcharge for a given monthly billing cycle.
(g) The strength and character of the sewage and wastes shall be based on the quantity of five-day biochemical oxygen demand, chemical oxygen demand, total suspended solids and ammonia-nitrogen as determined using the analytical methods approved in 40 CFR Part 136 for the analysis of wastewater.
(h) In a given monthly billing cycle, surcharges shall be assessed for each pound of surchargeable pollutant (i.e., cBOD5, COD, TSS or Ammonia-N) discharged to the POTW in excess of the allowable number of pounds of pollutant.
(i) Allowable pounds of each pollutant for each user in a given monthly billing cycle shall be calculated by multiplying the threshold concentration for the pollutant (in milligrams per liter)
by the total quantity of flow discharged to the POTW (in million gallons) by a conversion factor of 8.3453 pounds per gallon.
(j) Each pound of the following pollutants in excess of the allowable number of pounds for each pollutant shall be surcharged as follows:
POLLUTANT | THRESHOLD CONCENTRATION | RATE |
CBOD5 | 200 milligrams per liter | $0.423 per pound |
COD | 500 milligrams per liter | $0.933 per pound |
TSS | 250 milligrams per liter | $0.369 per pound |
NH3-N | 20 milligrams per liter | $0.562 per pound |
(3) Tax equalization assessment. The city shall impose a 25% tax equalization assessment upon all users that are not located within the corporate limits of the City of Kokomo. This assessment shall be calculated by multiplying a factor of 0.25 by the total assessments applicable under divisions (A)(2),(A)(2) and (A)(4) of this section.
(4) Non-residential surveillance fee. Users meeting the definition of a non-residential user as that term is herein defined shall be assessed a monthly fee equal to $105.52 (per user, per month) where the Superintendent determines that the implementation of the fee is necessary to defray the expense of additional oversight, monitoring and analysis, or other surveillance activities conducted by the city’s pretreatment team or other POTW personnel. Situations requiring additional oversight, monitoring and analysis, or surveillance activities may include, but are not limited to, the following categories:
(a) The user is regulated through an individual or general wastewater discharge permit issued by the City of Kokomo; or
(b) The user is a waste hauler that has been issued a written discharge authorization granting such user permission to discharge septage or other hauled wastes to the POTW’s designated septage receiving station; or
(c) The user is a party to a special discharge agreement with the City of Kokomo which regulates the user’s discharge to the POTW; or
(d) The Superintendent elects to impose such a fee for a short-term to defray the expense of additional surveillance activities implemented due to temporary changes in the nature of the user’s discharge; which, in the opinion of the Superintendent, require additional surveillance and oversight from the city’s pretreatment team or other POTW personnel.
(B) Wastewater processing fees and rates contained in this section shall be set periodically, as required, by separate ordinance titled, “Sanitary Sewerage Service Rate Ordinance.”
