Summary: On October 31, 2008, EPA approved the State of Alaska's application to administer and enforce an Alaska version of the National Pollutant Discharge Elimination System (NPDES) program under Section 402 of the Clean Water Act. The State administers the approved Alaska Pollutant Discharge Elimination System program through the Alaska Department of Environmental Conservation. EPA retains permitting and enforcement authorities for facilities operating outside state waters (generally 3 miles offshore), and others, such as facilities located in Indian Country.
