Description: This data shows the location of publicly owned treatment facilities and other facilities that discharge significantly to coastal surface waters at or near the contiguous U.S. Atlantic coast. This data originated from the <a href=https://www.epa.gov/npdes target="_blank">EPA National Pollutant Discharge Elimination System (NPDES)</a> <a href=https://www.epa.gov/frs target="_blank">Facility Registry Service (FRS)</a> data. The data was filtered to include primarily publicly owned wastewater treatment plans (POTW) and other facilties with major permits, as well as removing duplicate facilities with multiple permits. Facility locations were updated to more accurately represent the facility center. Additionally missing facilities were added where identified thorugh local research. Where possible, facilities were linked to outfall pipes and outfall discharge points (as separate features) using the provided key field.

Description: This data shows the location of outfall discharge points from publicly owned treatment facilities and other facilities that discharge significantly to coastal surface waters at or near the contiguous U.S. Atlantic coast. This data originated from the <a href=https://echo.epa.gov/ target="_blank">EPA Enforcement and Compliance History Online (ECHO)</a> <a href=https://echo.epa.gov/tools/data-downloads/icis-npdes-download-summary target="_blank">Integrated Compliance Information System National Pollutant Discharge Elimination System (ICIS-NPDES)</a> data. The data was filtered to include primarily outfall discharge points for publicly owned wastewater treatment plans (POTW) and other facilties with major permits. Additionally, the data was updated to represent the actual water discharge point(s) for each facility, where they could be identified either from permit information or seen from aerial imagery. All outfall discharge points are linked to their facility (as separate features) using the provided key field.

Description: This data shows the location of outfall discharge pipelines from publicly owned treatment facilities and other facilities that discharge significantly to coastal surface waters at or near the contiguous U.S. Atlantic coast. This data originated from <a href=https://encdirect.noaa.gov/ target="_blank">NOAA Office of Coast Survey – Electronic Navigation Charts (ENC)</a> data. Pipelines related to these types of facilities were filtered from the ENC data. The location of the discharge pipeline was updated where possible based on permit or other data. Additional discharge pipelines were included where identified from other resources. All outfall discharge pipelines are linked to their facility (as separate features) using the provided key field.
