Stormwater management plays an important role in protecting our lakes, rivers, creeks and wetlands. The City of Fairmont is located in the Blue Earth River watershed and its storm sewer system discharges directly to our chain of lakes, which flow to the Blue Earth River. The pollutants carried off of our streets, parking lots and property can affect the water quality in our lakes and rivers, which are used for public recreation, aquatic life and most importantly, consumption.

Regulatory Background
Water quality deterioration has prompted the US-EPA to mandate the City of Fairmont to comply with Phase II of the Stormwater Management Program. They City of Fairmont has an important role in maintaining and improving water quality.

The city is responsible to maintain a Minnesota General National Pollution Discharge Elimination System (NPDES) Permit for Small Municipal Separate Storm Sewer Systems (MS4s).
