The city sewer system is designed and constructed primarily for collection and transmission of sanitary sewage. Therefore, it is the policy of the city that any customer engaged in any business that generates liquid wastes which can be expected to have, prior to any pretreatment, one or more characteristics exceeding the limits listed in the § 50.01 definition of sanitary sewage shall:
(A) Include pretreatment process and/or facilities into the design and operation of his business. Unless issued a specific permit to do otherwise, the pretreatment shall ensure that sewage discharged into the city sewer system meets or exceeds the criteria defined in this section for sanitary sewage.
(B) At the time of application for connection to the sewer system, also apply for a permit to operate the pretreatment processes. The application shall include a description of the waste characteristics prior to pretreatment, a description of the proposed pretreatment to be applied, and a description of the sewage characteristics proposed for discharge into the sewer system. The permit will be issued only if:
(1) The discharge will meet or exceed the criteria for sanitary sewage.
(2) Or, meeting those criteria is not economically feasible, the proposed characteristics are as close to sanitary sewage as is economically feasible, and the proposed characteristics will not produce an unacceptable potential hazard to public health and safety, or potential adverse impact upon the sewer system or treatment processes.
(C) Upon receipt of the permit, pay a permit fee in accordance with § 50.08(B).
(D) The permit shall stipulate the specific conditions which the operation shall satisfy, and the period for which the permit shall be effective. In general, if the permit allows discharges exceeding the sanitary sewage criteria, then the permit shall stipulate a one year period of effectiveness, and require that the property owner construct and maintain facilities suitable for monitoring and metering the sewage prior to discharge into the sewer system. Prior to the end of the effective period, the property owner shall apply for a new permit. That application shall include analyses of actual characteristics of the wastes before and after pretreatment, performed within ten days of the date of application. Each new permit shall require payment of a new permit fee in accordance with § 50.08(B).
(E) If the permit is for discharges meeting the sanitary sewage criteria, then no special monitoring facilities shall be required. However, the owner shall submit annual analyses of his sewage before and after pretreatment, and the city shall randomly require submittal of unscheduled analyses. The permit shall have an indefinite effective period. However, it shall be canceled at any time that the owner fails to take timely action to correct any violations of the terms of the permit.
(F) If, at any time in the future, the City Commission authorizes connection to the city’s sewer system by an “EPA Contributing Industry”, as defined herein, then a permit issued to that customer shall require compliance with “Pretreatment Standards for Incompatible Pollutants” as described in Federal Regulations 40 CFR 128.133, and any other regulations as shall be established from time to time by appropriate governmental regulating agencies.
