Stormwater-General
National Summary
Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. Such runoff accumulates debris, chemicals, sediment, and other pollutants and is a major source of pollution that damages rivers, lakes, streams, and coastal waters of the United States. To address this problem, the U.S. Environmental Protection Agency (EPA) has developed a federal program under the Clean Water Act's (CWA) National Pollutant Discharge Elimination System (NPDES) program to regulate stormwater discharge sources. The CWA prohibits any person from discharging pollutants into a waterway from a point source unless a permit issued either by the EPA or an authorized state agency authorizes the discharge.
