The Outer Continental Shelf Lands Act (OCSLA) of 1953 (43 U.S.C. §§ 1331–1356) established federal jurisdiction over the submerged lands of the outer continental shelf beyond state water boundaries. It governs leasing, permitting, and development of natural resources on the OCS, including oil, gas, and increasingly offshore wind energy. Amendments over the decades have updated the permitting process to include environmental review requirements. The Interior Department administers the law, primarily through the Bureau of Ocean Energy Management (BOEM). The Trump administration in 2026 reinterpreted the OCSLA to impose stricter standards for offshore wind projects, a reinterpretation that Judge Casper blocked.
