The Environmental Protection Agency (EPA or the Agency) is not establishing at this time new requirements for hazardous substances under Clean Water Act (CWA) section 311. This section directs the President to establish procedures, methods, and equipment and other requirements for equipment to prevent discharges of oil and hazardous substances from vessels and from onshore facilities and offshore facilities, and to contain such discharges. The EPA has been delegated and/or redelegated authority for certain facilities as identified below. On July 21, 2015, a lawsuit was filed against the EPA for failing to comply with the alleged duty to issue regulations to prevent and contain CWA hazardous substance discharges under CWA section 311. On February 16, 2016, the United States District Court for the Southern District of New York entered a Consent Decree between the EPA and the litigants that required a notice of proposed rulemaking pertaining to the issuance of hazardous substance regulations, and a final action after notice and comment. After seeking public comment and based on an analysis of the frequency and impacts of reported CWA Hazardous Substances discharges, as well as the existing framework of EPA regulatory requirements, the Agency is not establishing at this time new discharge prevention and containment regulatory requirements under CWA section 311.
