(A) Users shall provide necessary wastewater treatment as required to comply with this subchapter and shall achieve compliance with all national categorical pretreatment standards within the time limitations as specified by the federal pretreatment regulations. Any facilities required to pretreat wastewater 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 Director for review and shall be acceptable to the Director before construction of the facility. The review of such plan and operating procedure will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the Director under the provisions of this subchapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the Director prior to the user's initiation of the changes.
(B) All records relating to compliance with pretreatment standards shall be made available by the Director to officials of the EPA or MPCA upon request.
(C) Any user subject to a national categorical pretreatment standard, after the compliance data of such pretreatment standard, or, in the case of the commencement of a new discharge to the wastewater disposal system, shall submit to the Director during the months of June and December, unless required more frequently in the pretreatment standard or by the Director, a report indicating the nature and concentration of pollutants in the effluent which are limited by such pretreatment standards or requirements. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation and maintenance and/or pretreatment is necessary to bring the facility into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by the user and certified to by a qualified professional.
