If any waters or wastes are discharged or are proposed to be discharged to the public sanitary sewer system which contain substances or possess characteristics which, in the opinion of the Director of the Wastewater Department, may have a deleterious effect upon the treatment facility, processes, equipment, receiving waters, including violations of applicable water quality standards or which otherwise create a hazard to life or constitute a public nuisance, the Director may: reject the waste; require pretreatment to an acceptable level for discharge; require control over the quantities and rates of discharges; and/or require the payment of a surcharge to cover the added cost of handling and treating the wastes under the provisions of these Rules and Regulations and in accordance with U.S. E.P.A. pretreatment regulations as described in 40 CFR, Subchapter N, parts 400, et seq. The industrial waste pretreatment program shall hereinafter be referred to as the IWPT program. No provision of this section shall be construed as authorizing a variance from the provisions of the National Categorical Pretreatment Standards.
(a) All industrial wastes discharged to the public sanitary sewer system shall, as a minimum, meet the applicable Categorical Pretreatment Standards or best practical control technology currently available for incompatible pollutants as published in CFR Title 40, Part 128, unless the treatment plant is committed in its NPDES permit to remove a specified percentage of the incompatible pollutants. In those instances, the applicable pretreatment standards may be correspondingly reduced by the Director or OEPA.
(b) If the Director permits or requires pretreatment or equalization of waste flows, the design and installation of facilities and equipment shall be subject to review and approval of the Director, City Engineer and OEPA. When such facilities are provided they shall be constructed, operated and maintained at the owner's expense. Further, the facilities shall be maintained in satisfactory and effective condition by the owner in accordance with all applicable specifications, ordinances, laws and with the particulars of 40 CFR, 40.3.
