About NPDES
Created by the 1972 Federal Pollution Control Act, the National Pollutant Discharge Elimination System (NPDES) Permitting Program authorizes discharges from point sources to waters of United States. A "point sources" is any discernible, confined and discrete conveyance, such as a pipe, ditch, channel, tunnel, conduit, discrete fixture, or container. It also includes vessels or other floating craft from which pollutants are or may be discharged. By law, the term "point source" also includes concentrated animal feeding operations, which are places where animals are confined and fed.
