§ 51.21 PRETREATMENT OF WASTEWATER.
   (A)   Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in § 51.15 within the time limitations specified by EPA, the state, or the Superintendent, 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 Superintendent for review, and shall be acceptable to the Superintendent 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.
   (B)   Accidental discharge/slug discharge control plans. The Superintendent shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Superintendent may require any user to develop, submit for approval and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the Superintendent may develop such a plan for any user. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
      (1)   Description of discharge practices, including nonroutine batch discharges;
      (2)   Description of stored chemicals;
      (3)   Procedures for immediately notifying the Superintendent of any accidental or slug discharge, as required by § 51.24(F); and
      (4)   Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents and/or measures and equipment for emergency response.
   (C)   Hauled wastewater. The city does not accept the introduction of hauled wastewater into the POTW.
