National Pollution Discharge Elimination System Permit

Water pollution degrades surface waters making them unsafe for drinking, fishing, swimming and other activities. As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters, such as streams, rivers and lakes. Since its introduction in 1972, the NPDES permit program is responsible for significant improvements to our Nation's water quality.

Stormwater runoff is directed to the storm drain system and flows directly into streams and rivers without treatment. The NPDES permit program requires the city to minimize stormwater pollution by implementing "best management practices" across the city.

The city implements these best management practices by developing a Stormwater Quality Management Plan (SQMP); submitting an Annual Compliance Report; and maintaining compliance with our NPDES Permit. In 2019, the City submitted an Interim SQMP to the Kansas Department of Health and Environment. This Interim SQMP details activities and best management practices from 2019 to the point when a new NPDES permit is delivered to the City.
