Wastewater Discharge Permits

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

The National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources such as pipes or man-made ditches that discharge pollutants to surface waters. Industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.
