A. Annual Review Of Wastewater Service Charges: The city shall review not less often than every year the wastewater contribution of users and user classes; the total costs of operation, maintenance, replacement and debt service of the treatment works; and its approved user charge system. The city shall revise the charges as required annually for users or user classes to accomplish the following:
1. Maintain the proportionate distribution of operation, maintenance, replacement and debt costs among users and user classes as required herein;
2. Generate sufficient revenue to pay the total operation, maintenance, replacement and debt costs necessary to the proper operation, maintenance and replacement of the treatment works; and
3. Apply excess revenues collected from a class of users to the costs of operation and maintenance attributable to that class for the next year and adjust the rate accordingly.
B. Pollutants: The user charge system shall provide that each user which discharges any pollutants which cause an increase in the cost of managing the effluent or the sludge of the treatment works shall pay for such increased costs.
C. Charges For Operation And Maintenance For Extraneous Flows: The user charge system shall provide that the costs of operation, maintenance, replacement and debt for all flows not directly attributable to users (i.e., infiltration/inflow and sewer line cleaning) be distributed among all users of the treatment works system in the same manner that the city distributes the costs of operation, maintenance, replacement and debt among users (or user classes) for their actual use.
D. Notification: Each user shall be notified, at least annually, in conjunction with a regular bill, of the rate and that portion of the user charges which are attributable to wastewater treatment and collection services. Public informational meetings may be held annually.
E. Inconsistent Agreements: The city may have preexisting agreements which address: 1) the reservation of capacity in the city's treatment works, or 2) the charges to be collected by the city in providing wastewater treatment services or reserving capacity. The user charge system shall take precedence over any terms or conditions of agreements or contracts between the city and users (including industrial users, special districts, other municipalities, or federal agencies or installations) which are inconsistent with the requirements of section 204(b)(1)(A) of the act and this chapter.
