Any facilities required to pretreat wastewater to a level in compliance with the limitations set by the permit shall be provided and maintained at the user’s expense. Plans, compliance schedules, and operating procedures shall be submitted to the Director for review, and shall be acceptable to the Director 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 Director under the provisions of <cite data-path="|25">this article</cite> and the wastewater discharge permit. Acceptance of plans and operating procedures does not constitute acceptance of the level of the treatment provided by such facilities and operations. Nor does the City thereby accept any responsibility for, or provide any guarantee as to, the performance of the facilities and operations. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the Director. No user shall 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 any local, state, or federal discharge standard. City Code, 1976/83, art. 25, §7(d)(2) Ord. 84-129 Ord. 91-775
