National Pollutant Discharge Elimination System (NPDES)

The National Pollutant Discharge Elimination System (NPDES) is a regulatory program in the United States aimed at controlling water pollution. It requires industries, municipalities, and other entities that discharge pollutants into waterways to obtain permits. These permits set limits on the amount and types of pollutants allowed and ensure that discharges comply with environmental standards. The NPDES is part of the Clean Water Act, designed to protect and restore the health of lakes, rivers, and streams, ultimately safeguarding public health and the environment.
