Abstract: This map service contains GIS data for Facilities that Discharge to Water. The information supporting this service resides in the Reach Address Database (RAD) which is part of the Watershed Assessment, Tracking & Environmental Results System (WATERS).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. When a RAD Source_FeatureID value is nine characters (the NPDES ID alone) the event is indexed against the location of the NPDES facility. This location may or may not correspond well with the location of actual outflows. When a RAD Source_FeatureID is twelve or thirteen characters (NPDES ID + PIPE SCHEDULE ID) this event is indexed against the location of the outflow as stored in NPDES. Thus a given NPDES facility id may be expressed as a single event indexed to the facility or one more events indexed to corresponding facility pipe schedules. The Source_DataDesc field provides a shorthand for this with three possible values: "FAC no PIPE" indicates the facility provided no pipe outflows to NPDES and thus the facility location is indexed; "PIPE" indicates the record is a pipe outflow and this pipe location is indexed; "FAC bad PIPE" indicates the facility has pipe outflow information in NPDES but the pipe locations cannot be indexed. In this situation the facility location is indexed instead.For complete metadata, please use EPA's Environmental Data Gateway (EDG): https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B091FC504-8762-8E7F-DCD7-513F648BC5B5%7D.
Purpose: This EPA Office of Water hosted web service contains a point layer depicting Facilities that Discharge to Water indexed to NHDPlus version 2.1. NPDES is used by EPA programs, regions, states, and water programs for monitoring water quality.

Supplemental information: 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).

Process step:
Process description: On a monthly basis, the FRS_FACILITY_SITE_SDE layer is created from FRS_FACILITY_SITE table. The layer has QA/QC performed for county validation and a 100 km flag. After QA/QC is performed, information is made available to Envirofacts, where it is extracted and made available as a service on geodata.epa.gov. For more information about the data provided within the Envirofacts database, please visit http://www.epa.gov/enviro/html/ef_overview.html
When the process occurred:
Date/Time: 2015-01-01
Process step:
Process description: A batch indexing process was used to create NHD event tables. Event identifiers were populated with the NPDES IDs that match the IDs in EPA's ICIS database. In some cases a State or Region validated and potentially updated the locations of these NPDES pipe schedules and facilities.
