(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.

(A) Information and data on a user obtained from applications, permits, monitoring programs and inspections shall be available to the public or other government agencies without restriction unless the user specifically requests and is able to demonstrate to the satisfaction of the Director that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets of the user.
(B) When requested by the person furnishing a report, and until such time as the information is determined not to be confidential, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public but shall be made available upon written request to governmental agencies for uses related to this subchapter, the NPDES permit, state disposal system permit and/or the pretreatment programs; provided, however, that such portions of a report shall be available for use by the state or any state agency in judicial review or enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics will not be recognized as confidential information. Information accepted by the Director as confidential shall not be transmitted to any governmental agency or to the general public by the Director until and unless a ten-day notification is given to the user.

Sludges, floats, skimmings, and the like generated by an industrial or commercial pretreatment system shall not be placed into the city's wastewater disposal system. Such sludges shall be contained, transported, and disposed of in accordance with all federal, state, and local regulations.

(A) The Director may suspend the wastewater treatment service of a user or a wastewater discharge permit after informal notice to the discharger when suspension is necessary, in the opinion of the Director, in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons, to the environment or to the wastewater disposal system or would cause the city to violate any condition of its NPDES or state disposal system permit.
(B) Any user notified of a suspension of the wastewater treatment service and/or the wastewater discharge permit shall immediately stop the discharge. In the event of a failure of the user to comply voluntarily with the suspension order, the Director shall take such steps as deemed necessary, including immediate severance of the sanitary sewer connection, to prevent or minimize damage to the wastewater disposal system or endangerment to any individuals. The Director shall reinstate the wastewater discharge permit and/or the wastewater treatment service upon proof of the elimination of the noncomplying discharge. A detailed written statement submitted by the user describing the causes of the slug or accidental discharge and the measures taken to prevent any future occurrence shall be submitted to the Director within 75 days of the date of occurrence.
(Ord. 297, passed 3-1-2022)
In accordance with the procedures of this subchapter, the Director may revoke the permit of any user which fails to factually report the wastewater constituents and characteristics of his or her discharge; which fails to report significant changes in wastewater constituents or characteristics; which refuses reasonable access to the user's premises for the purpose of inspection or monitoring or for violation of conditions of its permit, this subchapter or applicable state and federal regulations.
