This bill, titled the "Offshore Lands Authorities Act of 2025," aims to reverse specific past executive actions and significantly restrict future Presidential authority over unleased offshore lands. It explicitly nullifies several Presidential withdrawals of unleased offshore areas from mineral leasing, including those affecting the Arctic, North Aleutian Basin, Northern Bering Sea, Atlantic coast, and Gulf of Mexico. These nullified actions date from 2014 through 2025, effectively reopening these areas for potential leasing. The legislation amends the Outer Continental Shelf Lands Act to impose new limitations on the President's power to withdraw unleased offshore lands. Future withdrawals are restricted to a maximum of 150,000 acres and a duration of no more than 20 years . Additionally, no President may cumulatively withdraw more than 500,000 acres without explicit Congressional approval. Before any new withdrawal, the bill mandates that the Secretary complete several assessments . These include a geophysical and geological mineral resource assessment, an evaluation of the economic, energy, and national security value of identified mineral deposits, and an assessment of the expected reduction in future Federal revenues. The results of these comprehensive assessments must then be reported to relevant Congressional committees. The bill also establishes an expedited Congressional disapproval procedure for Presidential withdrawals. This process allows Congress to pass a joint resolution to nullify a withdrawal, which, if enacted, prevents the withdrawal from taking effect or continuing. A disapproved withdrawal cannot be reissued in a substantially similar form without new legislative authorization, and judicial review of this disapproval process is explicitly prohibited.
