A. Mandatory Permits: All significant industrial users proposing to connect or to commence a new discharge to the wastewater disposal system shall obtain a wastewater discharge permit before connecting to or discharging into the wastewater system. All existing significant industrial users or industrial users subject to federal pretreatment standards under sections 307(b) and (c) of the act connected to or discharging into the wastewater disposal system shall obtain a wastewater discharge permit within ninety (90) days after the effective date of this chapter.
1. The city may determine that an industrial user subject to categorical pretreatment standards is a non-significant categorical industrial user rather than a significant industrial user on a finding that the industrial user never discharges more than one hundred (100) gallons per day (gpd) of total categorical wastewater (excluding sanitary, non-contact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:
a. The industrial user, prior to the city's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
b. The industrial user annually submits a certification statement, together with any additional information necessary to support the certification statement; and
c. The industrial user never discharges any untreated concentrated wastewater.
2. Upon a finding that a user has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the city may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant industrial user.
3. The city may require other users to obtain individual wastewater discharge permits as necessary to carry out the purposes of this chapter.
4. Any violation of the terms and conditions of an individual wastewater discharge shall be deemed a violation of this chapter and subjects the wastewater discharge permittee to the sanctions set out in section 7-2-10 of this chapter. Obtaining an individual wastewater discharge permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, and local law.
B. Permit Application: Users required to obtain a wastewater discharge permit shall complete and file with the city an application in the form prescribed by the city and accompanied by a fee (fees set by council). Existing users shall apply for a wastewater discharge permit within thirty (30) days after the effective date of this chapter, and proposed new users shall apply at least ninety (90) days prior to connecting or discharging to the wastewater disposal system. In support of the application, the user shall submit, in units and term appropriate for evaluation, the following information:
1. Name, address and location (if different from the address);
2. SIC number according to the standard industrial classification manual, bureau of the budget, 1972, as amended;
3. Wastewater constituent and characteristics including, but not limited to, those governed by section 7-2-4 of this chapter as determined by a reliable analytical laboratory; sampling and analysis shall be performed in accordance with procedures established by the EPA pursuant to section 304(g) of the act and contained in 40 CFR, part 136, as such statute and regulations may be from time to time amended, supplemented or replaced;
4. Time and duration of discharge;
5. Average daily and thirty (30) minute peak wastewater flow rates, including daily, monthly and seasonal variation, if any;
6. Site plans, floor plans, mechanical and plumbing plans and details to show all sewer, sewer connections and appurtenances by the size, location and elevation;
7. Description of activities, facilities and plant processes on the premises including all materials which are or could be discharged;
8. Where known, the nature and concentration of any pollutants in the discharge which are limited by any city, state or federal pretreatment standards, and (for an existing discharge) a statement regarding whether or not the pretreatment standards are being met on a consistent basis and if not, whether additional operation and maintenance and/or additional pretreatment is required for the user to meet applicable pretreatment standards;
9. Each product produced by type, amount and rate of production;
10. Type and amount of raw materials processed (average and maximum per day);
11. Number of full- and part-time employees, and hours of work;
12. Any other information as may be deemed by the city to be necessary to evaluate the permit application. The city will evaluate the data furnished by the user and may require additional information. After evaluation and acceptance of the data furnished, the city may issue a wastewater discharge permit subject to terms and conditions provided herein or deny the application.
a. The city may deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its NPDES permit.
