This layer displays a point layer depicting Facilities that Discharge to Water indexed to NHDPlus version 2.1. National Pollutant Discharge Elimination System (NPDES) is used by EPA programs, regions, states, and water programs for monitoring water quality. Discharge of pollutants into waters of the United States is regulated under the 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). The NPDES permit program addresses water pollution by regulating point sources that discharge pollutants to waters of the United States.
303(d) Impaired Waterbodies
This layer displays impaired waterbodies, which means waterbodies not able to be used for certain purposes due to water quality from physical, chemical and biological factors.
Water Monitoring Locations
This layer displays GIS data from EPA Office of Water STORET Warehouse. Reach indexed NPDES locations comprise two basic types: facilities and pipes. For a given NPDES permit, the program may have locational information on the facility alone or specific pipe outfalls.
