Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical Pretreatment Standards, Local Limits, and the prohibitions set out in Section 930.2.1 within the time limitations specified by EPA, the State, or the General Manager, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the User's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the General Manager for review, and shall be acceptable to the General Manager before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the User from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the South Charleston Sanitary Board under the provisions of this article.
