(A) Permits shall contain sanitary sewer service rates for the term of the permit. The user shall apply for permit reissuance a minimum of 180 days prior to the expiration of the user's existing permit. The terms and conditions of the permit may be subject to modification by the Director during the term of the permit as limitation or requirements as identified in this subchapter are modified or either just cause exists. The user shall be informed of any proposed changes in his or her permit at least 30 days prior to the effective date of change. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance.
(B) The expiration of discharge permits will be determined on a case by case basis and included in the permit issuance.
(Ord. 297, passed 3-1-2022)
(A) Permits issued under the provisions of this subchapter may be modified by the city if the actual discharge is found to differ substantially in quantity, constituents or effects from the discharge which was permitted. The user with an existing wastewater discharge permit may request modification of the permit to change wastewater discharge limitations, monitoring requirements or other requirements. Requests for modifications which would allow increased loading to the wastewater disposal system shall be made at least 180 days prior to the date of the proposed change.
(B) The user with an existing wastewater discharge permit shall submit to the Director within 180 days after the promulgation of any applicable national categorical pretreatment standard the information required by § 52.097. If the information previously submitted in an application is still current and adequate, only a letter from the user certifying such is required.
(Ord. 297, passed 3-1-2022)
Wastewater discharge permits are issued to a specific user for a specific operation. A wastewater discharge permit shall not be reassigned or transferred or sold to a new owner, new user, different premises or a new or changed operation without the approval of the Director. Any succeeding owner or user shall also comply with the terms and conditions of the existing permit.
(Ord. 297, passed 3-1-2022)
(A) Monitoring facilities to allow inspection, sampling, and flow measurement of the building sanitary sewer and/or internal drainage systems shall be provided and operated by all industrial users. The monitoring facility should normally be situated on the user's premises, but the Director may, when such a location would be impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk area and located so that it will not be obstructed by landscaping or parked vehicles.
(B) There shall be ample room in or near such sampling manhole or facility to allow accurate sampling and compositing of samples for analysis. The facility and sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.
(C) Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the Director's requirements and all applicable local construction standards and specifications. Construction shall be completed within 90 days following written notification by the Director, unless a time extension is otherwise granted by the Director.
(Ord. 297, passed 3-1-2022)
The Director shall inspect the facilities of any user to ascertain whether the purpose of this subchapter is being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the Director ready access to all reasonable times to all parts of the premises for the purposes of inspection, sampling, records examination or in the performance of any of their duties. The Director, MPCA and EPA shall have the right to set up on the user's property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with any security guards so that upon presentation of suitable identification, the Director, MPCA and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.
(Ord. 297, passed 3-1-2022)
(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.
(Ord. 297, passed 3-1-2022)
(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.
(Ord. 297, passed 3-1-2022)
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.
(Ord. 297, passed 3-1-2022)
(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.
