These programs are required under the National Pollutant Discharge Elimination System or NPDES program through the Environmental Protection Agency or EPA. The NPDES program requires counties and municipalities nationwide to apply for a permit that regulates local stream health or water quality. These permits are called (M)unicipal (S)eparate (S)torm (S)ewer (S)ystem or MS4 permits
