Congressional Oversight of the Antiquities Act

Introduced: Apr 3, 2025
Standard Summary
Comprehensive overview in 1-2 paragraphs

This bill, titled the Congressional Oversight of the Antiquities Act, would amend the Antiquities Act to insert a mandatory congressional review window into the process of designating national monuments or reserving land. Under the measure, a national monument designation (or land reservation) would automatically be limited to a 6-month period or end of the current Congress, unless Congress extends or modifies it by statute. If the designation is not extended or modified during that period (or rejected by statute), the land could not be included in future national monument designations under this act for 25 years. The goal is to require explicit congressional action for ongoing or future monument designations, effectively adding a formal oversight and delay mechanism.

Key Points

  • 1Creates a new subsection (c) of the Antiquities Act (54 U.S.C. 320301) adding a time limit on monument designations.
  • 2A national monument designation or land reservation is effective only until the earlier of: (a) six months after establishment/reservation, or (b) the last day of the Congress in session at the time of establishment/reservation.
  • 3If the monument designation or land reservation is not extended or modified by statute during that period, or is rejected by statute, the land may not be included in the extension or establishment of a monument under this section for 25 years.
  • 4Requires legislative action (extension or modification by statute) for continuing or enlarging a monument beyond the initial period.
  • 5The bill renumbers certain subsections of the Antiquities Act (designating the new language as subsection (c) and adjusting subsequent subsections accordingly).

Impact Areas

Primary affected group/area: Federal land management authorities (e.g., National Park Service, U.S. Fish and Wildlife Service), Congress (as the gatekeeper for extensions/modifications), and entities seeking monument designations.Secondary affected group/area: States, local governments, landowners, and communities adjacent to or near potential monument land, whose planning and land-use decisions could be influenced by the need for congressional action to maintain or alter designations.Additional impacts: Could slow or block unilateral presidential designations of national monuments, increasing legislative workload and oversight requirements; potential implications for conservation groups, energy or resource interests, and recreation sectors depending on whether designations are extended or rejected. May affect funding, management plans, and local economic activity tied to protected lands.
