PART V. STORMWATER MANAGEMENT PROGRAM
A. Stormwater Management Program
The Permittee shall develop, and as necessary continue to develop, implement, and enforce a Stormwater Management Program designed to reduce the discharge of pollutants from the municipal separate storm sewer system to the Maximum Extent Practicable (MEP), to protect water quality and to satisfy the appropriate water quality requirements of the Clean Water Act and the conditions of this permit. The Stormwater Management Program is an enforceable part of the permit.
The Stormwater Management Program shall be the document that describes in detail all activities related to the Permittees program for the management of stormwater in its jurisdiction in accordance with this permit and the appropriate water quality requirements of the Clean Water Act, including long-term goals (that may extend beyond the permit period), Minimum Control Measure-specific goals, priorities, strategies, monitoring, record keeping and reporting. The Stormwater Management Program shall cover at least the term of the permit and be based on an adaptive management system by which the Permittee continuously monitors, analyzes and adjusts the Stormwater Management Program to achieve pollutant reductions to the MEP. The Stormwater Management Program shall include the Minimum Control Measures (described in Part V.C.1 to 8 of this permit) and shall conform with the requirements of Part V.B to V.F of this permit.
Upon their approval by the Commissioner, modifications to the Stormwater Management Program are an enforceable part of the permit and shall be implemented as specified in the permit and in the Commissioner’s approval letter. Prior to approval by the Commissioner of the revised Stormwater Management Program, the Permittee shall continue to operate in accordance with this permit and the Permittee’s current Stormwater Management Program. The Permittee shall, upon the receipt of notice of the Commissioner’s approval of the revised Stormwater Management Program, commence operation under the revised Stormwater Management Program. Modifications to the Stormwater Management Program may be made through the Annual Report, required under Part V.E of this permit, in compliance with Part V.D. 3, 4 and 5 of this permit. Modifications to the Stormwater Management Program shall be implemented as specified in the Annual Report and in the Commissioner’s approval letter.
The Annual Report shall discuss progress toward achieving the long-term and Minimum Control Measure-specific goals of the Stormwater Management Program and shall modify as necessary the priorities, strategies, and monitoring of the Stormwater Management Program to achieve the long-term and Minimum Control Measure-specific goals. The Annual Report shall conform to the requirements of Parts V.E and VI.D of this permit.
B. Minimum Control Measure General Requirements
The Permittee shall manage, operate, and maintain its storm sewer system and areas that the Permittee controls that discharge to the storm sewer system in a manner to reduce the discharge of pollutants to the MEP. Each Minimum Control Measure shall consist of a combination of BMPs, including: system design and engineering methods; education; operation; maintenance; control techniques; a schedule for installation and/or implementation of planned BMPs; and such other provisions as the Permittee and/or Commissioner determines to be appropriate. The BMPS selected by the Permittee for the Minimum Control Measures shall meet the minimum requirements of this permit. In the development of Minimum Control Measures for the Stormwater Management Program, the Permittee shall consider the sources of pollutants and the sensitivity of the receiving waters.
For each Minimum Control Measure, the Stormwater Management Program shall include:
- 1. identification of potential sources and pollutants targeted for reduction;
- 2. a description of and the scope of the BMPs for each Minimum Control Measure;

The Permittee shall also develop, implement and enforce an ordinance or other mechanism, such as agreements with the owners of privately owned BMPs that were installed as a result of the Permittee’s requirements, for maintenance, inspection, record keeping and reporting. The Permittee shall maintain a list of privately owned BMPs for which the Permittee established such agreements;
e. establish BMP design requirements for new storm sewer projects and existing storm sewer addition or modification projects, consistent with reliable and efficient conveyance of stormwater, for:
1) reduction of runoff volume;

Training and training materials that are available from the United States Environmental Protection Agency (USEPA), MPCA, University of Minnesota, state and regional agencies, or other organizations may be used or modified as appropriate for the community. The program shall include employee training to prevent and reduce stormwater pollution from activities such as park and open space maintenance, public street maintenance and deicing, fleet and building maintenance, new construction and land disturbances, and stormwater system maintenance.
1) operate and maintain the municipal separate storm sewer system in a manner so as to reduce the discharge of pollutants to the MEP pursuant to Minn. R. 7001.0150, subp. 3(F). Proper operation and maintenance includes effective performance, adequate funding, adequate operator staffing and training, and adequate laboratory and process controls, including appropriate quality assurance procedures required to insure compliance with the conditions of this permit. Provide training for staff critical to the operation and maintenance of structural pollution control devices.
2) dewater and dispose of solids, floatables, dredgings, or other pollutants resulting from the control and/or treatment of stormwater, in such a manner so as to prevent any pollutant from such materials from entering waters of the state. The Permittee, in disposing of such materials, shall comply with all applicable statutes and rules.
3) assess at least annually all structural pollution control devices, such as trap manholes, grit chambers, floatable skimmers and traps, separators, and other small settling or filtering devices. The Permittee shall assess catch basin sumps as established in the Commissioner-approved plan required under Part V.C.6.f of this Permit. All structural pollution control devices shall be assessed, where appropriate, using methods detailed in ““Gulliver, J.S., A.J. Erickson, and P.T. Weiss (editors). 2010. "Stormwater Treatment: Assessment and Maintenance." University of Minnesota, St. Anthony Falls Laboratory. Minneapolis, MN. http://stormwaterbook.safl.umn.edu/;
4) inspect, at minimum, twenty percent of the municipal separate storm sewer system outfalls, sediment basins and ponds for structural and functional integrity each year on a rotating basis. If additional erosion protection is necessary, the protection project shall be completed during the same year as the inspection or a schedule for completion shall be submitted in the Annual Report. Results of outlet inspections shall be reported in the Annual Report and include the dates of inspection and the date of completion of any additional erosion protection projects.
5) inspect for discharges, or the potential for discharges, all exposed stockpile, storage, and material handling areas. Inspections shall be weekly when material is being actively handled, used or disturbed on a daily basis and at least monthly when material is not being actively handled, used or disturbed. Incorporate controls, such as perimeter controls, at stockpiles that are not covered, to prevent material from entering the municipal separate storm sewer system.
