Section 14-117 Pretreatment facilities required.
(a) Industrial users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all federal categorical pretreatment standards and local limits and prohibitions as outlined in section 14-98 within the time limitations as specified by the federal, state or local pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the city and shall be prepared by a registered engineer before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the city under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to the city. The city in no way shall be responsible for the design and operation of the facilities. The review contemplated hereunder is intended only to assure compatibility of the pretreatment system with the city's system. (b) No industry will exceed the pretreatment limits as established by the EPA in accordance with section 307(b) and (c) of the Act (33 USC 1347) which applies to a specific category of industrial users. (c) No user shall ever increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with a discharge limitation unless expressly authorized by an applicable pretreatment standard or requirement. The superintendent may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate. (Ord. of 6-23-97, VII)
