National Pollution Discharge Elimination System (NPDES) Self-Monitoring Program

Description / purpose

The NPDES permit program, created in 1972 by the Clean Water Act (CWA), helps address water pollution by regulating point sources that discharge pollutants to waters of the United States. The permit provides two levels of control: technology-based limits and water quality-based limits (if technology-based limits are not sufficient to provide protection of the water body). NPDES requires self-monitoring for its permitting programs: stormwater, industrial, vessel, and municipal discharges.
