The surest way to improve water quality in Minnesota is to better manage stormwater. Unmanaged stormwater can have devastating consequences on the quality of lakes, streams and rivers we enjoy. Stormwater often contains oil, chemicals, excess phosphorous, toxic metals, litter, and disease-causing organisms. In addition, stormwater frequently overwhelms streams and rivers, scours stream banks and river bottoms and hurts or eliminates fish and other aquatic organisms.

To better manage stormwater across the state, the Minnesota Pollution Control Agency (MPCA) administers the requirements of the federal Clean Water Act in addition to its own State Disposal System requirements. At the MPCA, the Stormwater Program includes three general stormwater permits: the Municipal Separate Storm Sewer Permit, the Construction Stormwater Permit and the Industrial Stormwater Permit. Each program administers a general permit (and in some cases, individual permits) that incorporates federal and state requirements for Minnesota stormwater management. 

The Industrial Stormwater Program's goal is to reduce the amount of pollution that enters surface and ground water from industrial facilities in the form of stormwater runoff. This goal is accomplished by requiring permitted facilities to develop an effective Stormwater Pollution Prevention Plan (SWPPP) which contains Stormwater Control Measures using Best Management Practices (BMPs).
