Stormwater Management

What is the National Pollutant Discharge Elimination System (NPDES) Storm Water Program?

Mandated by Congress under the Clean Water Act, the NPDES Stormwater Program is a comprehensive two-phased national program for addressing the urbanized sources of storm water discharges that adversely affect the quality of our nation’s waters.  Phase I of the regulations was initiated in the early 1990’s for municipal separate storm water systems serving over 100,000 in population.  The NPDES Phase II Program extends this program to all remaining urbanized communities.  The program uses the NPDES permitting process to require the implementation of Minimum Control Measures designed to prevent harmful pollutants from being washed by storm water runoff into local water bodies.
