Oil & Gas NPDES Permits
EPA regulates discharges associated with offshore oil and gas exploration, development, and production activities on the outer continental shelf (OCS) under the Clean Water Act's (CWA) National Pollutant Discharge Elimination System (NPDES) program.
EPA Region 4 issues individual and general permits covering facilities that discharge beyond the offshore three-mile limit defining territorial seas in the Eastern Planning Area and in the Mobile and Viosca Knoll Blocks of the Central Planning Area. The issued permits meet all CWA requirements, as well as EPA's guidelines for determining the degradation of marine waters (Ocean Discharge Criteria Evaluation). New source discharges are subject to environmental review provisions of the National Environmental Policy Act (NEPA).
