(A)   Users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all federal categorical pretreatment standards within the time limitations as specified by the federal pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated, and maintained at the user's expense.  Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the city for review, and shall be acceptable to the city 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 city under the provisions of this chapter.  Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the city prior to the user's initiation of the changes.
   (B)   Any industrial user subject to the reporting requirements of this chapter, shall retain for a minimum of three years any records of monitoring activity and results (whether or not such monitoring activities were required) and shall make such records available for inspection and copying by the control authority or the approval authority.  This period of retention shall be extended during the course of any unresolved litigation regarding the industrial user, or when requested by the director or the regional administrator.
   (C)   All records relating to compliance with pretreatment standards shall be made available to officials of the EPA or approval authority upon request.
