(A) Permit required. No SIU shall discharge or cause to be discharged any industrial wastewaters directly or indirectly to the POTW owned by the city without first obtaining an SIU permit from the city.
1. Conditions of permit. The Director of Public Works may require an SIU permit to include pretreatment of industrial wastewaters before discharge, restriction of peak flow discharges, discharge of certain wastewaters only to specified sewers of the city, relocation of point of discharge, prohibition of discharge of certain wastewater components, restriction of discharge to certain hours of the day, payment of additional costs to defray increased costs of the city created by the industrial wastewater discharge and such other conditions as may be required to effectuate the purpose of this chapter.
2. Pretreatment standards. Users in industrial categories subject to the categorical pretreatment standards developed by the EPA under the act are required to comply with pretreatment standards promulgated pursuant to § 307 of the Act, being 33 U.S.C. § 1317. The city may issue standards more stringent than the federal standards if the Director of Public Works determines that the limitations in the federal standards are not sufficient to:
(a) Protect the operation of the city’s POTW; or
(b) Protect the POTW from violating the water quality standards or effluent limitations specified in the POTW’s waste discharge requirements.
3. Self-monitoring requirements. The SIU permits shall contain self-monitoring requirements deemed necessary by the Director of Public Works to ensure compliance with city, state or federal rules and regulations and shall be submitted to the city for approval. The Director of Public Works may require any or all of the following:
(a) A schedule for complying with effluent limitations;
(b) Compliance schedule progress reports;
(c) A report on final compliance with effluent limitations and standards; and
(d) Periodic reports on continued compliance.
(B) Amended SIU permits.
1. No person shall discharge industrial wastewaters in excess of the quantity or quality limitations set by the SIU permit. Any person desiring to discharge industrial wastewaters or use facilities which are not in conformance with the SIU permit or desiring to change its discharge parameters, shall apply to the city for an amended permit. An amended permit shall be issued before discharging at limits in excess of the current permit limits. Additional connection fees will be assessed and paid, for the increase in permit limits, as provided by Council fee resolution.
2. New or increased contributions of pollutants to the city sewage system by industrial users, where such contributions do not meet applicable national pretreatment standards and the requirements set forth in this chapter or where such contributions would cause the city to violate its waste discharge requirements, are prohibited, and no amended permit shall be issued for such contributions.
