All users shall:
(A) Pretreat wastewater in compliance with this chapter;
(B) Achieve compliance with all Federal Categorical Pretreatment Standards, as contained in 40 CFR Chapter I, Subchapter N, as it exists and as it may be amended, and Local Limits, whichever is more stringent, within the time limitations as specified by the federal pretreatment regulations;
(C) Pretreat wastewater to a level acceptable to the Director, and shall operate and maintain all necessary equipment, systems and devices at the user's expense;
(D) Provide detailed plans showing the pretreatment equipment, systems and devices and operating procedures. These plans shall be submitted to the Director for review and approval before the beginning of any construction or installation. The review of such plans and operating procedures, including Best Management Practices (BMPs), will in no way relieve the user from the responsibility of pre-treating wastewater to produce an effluent acceptable to the Director under the provisions of this chapter.
(1) The Director, at his or her discretion, may impose either equivalent concentration or mass limits. To be eligible for equivalent mass limits, the industrial user must employ, or demonstrate that it will employ water conservation methods and technologies that substantially reduce water use during the term of its individual discharge permit.
(2) The Best Management Practices (BMPs) may be imposed by ordinance or in individual discharge permits or general permits to implement Local Limits and requirements.
