Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all local limits, prohibitions and requirements set out in §
136-10, Prohibited discharge standards, §
136-11, Federal categorical pretreatment standards, and §
136-12, Local discharge restrictions, of this chapter, within the time limitations specified by the EPA, the state or the Director of Public Works, whichever is more stringent. All facilities required to achieve and maintain 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 Director of Public Works for review, and shall be acceptable to the Director of Public Works and the NHDES 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 city under the provisions of this chapter.
