To prohibit the implementation of the Proposed Resource Management Plan Amendment and Final Supplemental Environmental Impact Statement for the Miles City Field Office, Montana.

HR 9883 blocks the Bureau of Land Management (BLM) from finalizing or implementing a specific resource management plan amendment and environmental review for Montana's Miles City Field Office. The bill directly affects the BLM's operations in that office by prohibiting any action related to the May 2024 published plan and environmental impact statement (89 Fed. Reg. 43432). Its key mechanism is a clear prohibition on the Secretary of the Interior finalizing, implementing, administering, or enforcing that specific document. This is a procedural bill targeting one administrative action, not a broad policy change.
