These permits establish conditions for discharges of municipal stormwater systems to Waters of the State. There are two types of municipal stormwater permits; general permits for small municipal separate storm sewer systems (MS4s) and individual permits for larger municipal systems. The permits require a Stormwater Pollution Prevention Program (SWPPP) to be developed, implemented, and enforced by the permittee. The SWPPPs are public noticed and approved by the MPCA. Other requirements include system maintenance, pollution prevention and good housekeeping for municipal operations, and record keeping.

Refer to the NPDES/SDS MS4 General Permit

Stormwater Program for Municipal Separate Storm Sewer Systems (MS4)

The individual permits for Minneapolis and St Paul are effective January 21, 2011 - January 21, 2016.

Six minimum control measures are included in an MS4 SWPPP. MS4s must identify and implement appropriate best management practices (BMPs) for each of the control measures, and provide measurable goals for each BMP. The SWPPP must include for all BMPs, annual schedules or procedures for implementation, and where appropriate, must be implemented or established in ordinance, plan or policy by dates specified in the permit or a schedule established by the MPCA Commissioner.
