NPDES Wastewater Discharge Permits
Water is a critical resource that must be protected to supply safe drinking water and support various activities, such as farming, manufacturing, and tourism. The federal Clean Water Act (CWA) protects “waters of the United States” (WOTUS). This training provides general guidance on what waters are considered WOTUS. With certain exceptions, the CWA prohibits the discharge of pollutants from a point source into waters of the United States without a National Pollution Discharge Elimination System (NPDES) permit. The requirements of this permit are also covered in this training course.

Sample Video Transcript
The Clean Water Act prohibits the discharge of pollutants into a water of the United States without a National Pollution Discharge Elimination System (NPDES) permit. This includes direct discharges from publicly owned treatment works, industrial wastewater and stormwater, construction stormwater, municipal storm sewer discharges, discharges from concentrated animal feeding operations, and discharges from certain commercial vessels. Where applicable, dischargers can operate under a general permit. Otherwise an individual permit based on site-specific operations is required. All permits provide the effluent limits needed to protect downstream waters. The limits can be technology or water-quality based. Permittees are required to comply with all requirement specified in the permit.
