Storm-Water Discharge Permits

Certain types of industrial facilities must apply for a storm-water discharge permit from the MPCA. In addition, storm-water permits may be required for certain construction activities. Minnesota’s storm-water permitting program is designed to help improve the quality of the state’s waters by reducing or eliminating the chemicals and sediments carried into surface waters with storm-water runoff.

All required industrial facilities must apply for a general storm-water discharge permit from the MPCA. In addition, an industry-specific permit may be required depending on the environmental risk of storm-water runoff from the facility. Construction projects disturbing one or more acres must apply for a general NPDES storm-water permit from the MPCA. Storm-water permits may require the preparation of a plan for managing storm-water runoff, potentially including construction of holding basins or diversion structures.

If you have potential discharges find out if your industrial facility requires a storm-water permit. The MPCA and EPA have websites with information on the storm water permit programs. Check the MPCA home page and EPA storm-water page for information.
