All discharges of wastewater, gases or solids which are not similar to domestic sewage shall meet the following pretreatment requirements.
(A) This section adopts by reference the “General Pretreatment- Treatment Regulations for Existing and New Sources of Pollution”, promulgated by the United States Environmental Protection Agency, Title 40, Chapter I, Part 403, as published in the Federal Register, Vol. 46, No. 18, Wednesday, January 28, 1981, and amended on April 7, 1993, as the city pretreatment regulation.
(B) (1) Any industrial, commercial or other utility customer which discharges any sewage, industrial waste or other waste to the municipal sanitary sewer system shall comply with all regulations or requirements of the State Department of Natural Resources and/or the United States Environmental Protection Agency.
(2) Where regulations have not been set by those agencies, the Director of Public Works shall establish pretreatment requirements to obtain the following objectives:
(a) To prevent the introduction of pollutants which will interfere with the treatment plant operation or contaminate the resulting sludge;
(b) To prevent the introduction of pollutants which will pass through the system, inadequately treated, into the receiving waters or the atmosphere or otherwise be incompatible with the system; and
(c) To improve opportunity to recycle and reclaim wastewater and sludge from the system.
(C) Any costs for pretreatment flow measuring or monitoring facilities or analytical systems or tests to meet the pretreatment regulations shall be the responsibility of the customer.
(D) Any cost to the city, including increased operation or maintenance expenditures or fines levied by the state or federal agencies, which result from the discharge from any utility customer, shall be assessed to that customer. In the event more than one utility customer is responsible, the cost shall be prorated among those responsible based upon percent of total pounds of pollutants.
(E) No utility customer may expand his or her process or operation if that expansion results in a discharge or results in a discharge which exceeds any limitation established for their discharges or results in the discharge of some other substance which will violate any provision of the pretreatment regulations unless their plans for expansion are approved by the Director of Public Works at least six months prior to the planned expansion.
