This feature class contains integrated location, identification, and permit and discharge monitoring information from the EPA Facility Registry Service (FRS) for the subset of facilities that link to the Permit Compliance System (PCS)for a subset of for coastal facilities permitted under the National Pollutant Discharge Elimination System (NPDES) module of the Integrated Compliance Information System (ICIS). Coastal proximity was determined by selecting facilities located within 20 miles of submerged areas established in the Submerged Lands Act (SLA, 43 U.S.C. sect. 1301 et seq.), 48 U.S.C. sect. 1705, or that overlapped the Exclusive Economic Zone (EEZ) for facilities in regions outside the SLA. The Facility Registry Service (FRS) identifies and geospatially locates facilities, sites or places subject to environmental regulations or of environmental interest. PCS tracks NPDES surface water permits issued under the Clean Water Act. Under NPDES, all facilities that discharge pollutants from any point source into waters of the United States are required to obtain a permit. The permit will likely contain limits on what can be discharged, impose monitoring and reporting requirements, and include other provisions to ensure that the discharge does not adversely affect water quality. Using vigorous verification and data management procedures, FRS integrates facility data from EPA's national program systems, other federal agencies, and State and tribal master facility records and provides EPA with a centrally managed, single source of comprehensive and authoritative information on facilities.

These data show the location of available and discontinued ocean disposal sites within U.S. waters. Contemporary ocean disposal sites generally accept clean dredged material (sediment) collected during navigation channel improvement projects. These projects are sponsored and-or regulated by federal and state agencies. The terminology and practices used in ocean disposal have changed considerably over time. The values in the Primary Use field in this database show some of that variability.

This geospatial dataset depicts a sewage no-discharge zone established under Clean Water Act Section 312. The area(s) depicted are zones where the discharge of any sewage, treated or untreated, from vessels is prohibited. This layer was created using information from the corresponding Federal Register notice and is created for informational purposes, not to be used for enforcement.
