From the Document: "Three entities in the Department of the Interior (DOI) share responsibility for managing the nation's ocean energy resources on almost 2.5 billion acres of the U.S. outer continental shelf (OCS). The Bureau of Ocean Energy Management (BOEM) administers offshore energy leasing and mineral development; the Bureau of Safety and Environmental Enforcement (BSEE) oversees offshore operational safety and environmental protection; and the Office of Natural Resources Revenue (ONRR) manages public revenues from federally regulated offshore and onshore energy and natural resource projects. BOEM, BSEE, and ONRR receive appropriations in the annual Interior, Environment, and Related Agencies appropriations bill. Issues include determining the aggregate and program-level appropriations for each entity."
