NPDES
National Summary
The National Pollutant Discharge Elimination System (NPDES) permit program was established under the Clean Water Act (CWA) and regulates discharges of pollutants from point sources (pipe, ditch, well, etc.) to U.S. waters. Under NPDES, all facilities that discharge pollutants from any point source into waters of the United States are required to obtain a permit. The permit provides two levels of control: technology-based limits (based on the ability of dischargers in the same industrial category to treat wastewater) and water-quality-based limits (if technology-based limits are not sufficient to provide protection of the water body).
