(A) Users shall provide necessary wastewater treatment as required to comply with this subchapter. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated and maintained at the user's expense.
(B) Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Director of Engineering for review, and must be approved by the Director of Engineering before construction of the facility. The review of the plans and operating procedures will not relieve the user from the responsibility as necessary to produce an effluent acceptable to the city. 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.
(C) All records relating to compliance with pretreatment standards shall be made available by the city to officials of the EPA or MPCA on request.
