§ 12.11.020. Pretreatment facilities and operation.

A wastewater pretreatment device or system may be required by the city manager to pretreat industrial wastewater before discharge to the sewerage system. Pretreatment may be necessary to restrict or prevent the discharge of certain waste constituents, to distribute more equally over a longer time period any peak discharges of industrial wastewaters, or to accomplish any pretreatment results required by this title (40 CFR 403.8(f)(1)(ii)). Pretreatment facilities required by the city manager shall be maintained in good working order and operated as efficiently as possible, at the expense of the discharger, and are subject to the requirements of this title. Where pretreatment or flow equalization prior to discharge into the sewerage system is required, plans, specifications and other pertinent data and information relating to such pretreatment or flow control shall first be submitted to the city manager for approval. Such approval shall not exempt the discharger from compliance with the requirements of any other governmental authority. No alteration or addition to such pretreatment facilities shall be made without the city manager's prior review and approval. All federal pretreatment standards applicable to local industry which specify quantities or concentrations of pollutants that may be discharged by a specific industrial subcategory shall be enforced by the city as required in Section 309(e) and (f), et seq., of the Act. Existing industrial users shall comply with categorical pretreatment standards within three years of the date the standard is promulgated, unless a shorter time is specified by the EPA. All domestic wastewaters including, but not limited to, those from restrooms, showers and drinking fountains shall be kept separate from industrial wastewaters until the industrial wastewaters have passed through any required pretreatment or monitoring device or system.
