This legislation, titled the Moab UMTRA Project Transition Act of 2025 , amends the Strom Thurmond National Defense Authorization Act for Fiscal Year 1999. Its primary purpose is to facilitate the transfer of the federal government's interest in the Moab site to Grand County, Utah , without cost to the county. This transfer is a significant step in the long-term management of the former uranium mill tailings site. The conveyance is contingent upon the site achieving a sufficient remedial action completion status, as determined by the Secretary of Energy in consultation with relevant regulatory authorities. It will also be subject to any necessary regulatory or use restrictions designed to protect human health and safety, potentially including those under the Uranium Mill Tailings Radiation Control Act of 1978 and related federal regulations. Furthermore, the Secretary of Energy will retain specific water rights deemed necessary for ongoing responsibilities related to the site's remediation, especially if groundwater remediation is still active at the time of transfer. A crucial provision of the bill explicitly prohibits Grand County from subsequently reconveying any portion of the transferred land to a private entity or nonprofit organization, ensuring the land remains under public control. Additionally, the Secretary of Energy retains the authority to impose any further terms and conditions deemed necessary to safeguard the interests of the United States during this transition. This ensures a responsible and controlled transfer of the site.
