EPA Office of Water (OW): Facilities that Discharge to Water NHDPlus Indexed Dataset
Discharge of pollutants into waters of the United States is regulated under the National Pollutant Discharge Elimination System (NPDES), a mandated provision of the Clean Water Act. To assist with the regulation process, state and federal regulators use an information management system called the Integrated Compliance Information System (ICIS-NPDES). ICIS-NPDES stores data about NPDES facilities, permits, compliance status, and enforcement activities. ICIS-NPDES replaces the legacy Permit Compliance System (PCS).
NPDES is used by EPA programs, regions, states, and water programs for monitoring water quality.
