Legacy Mine Cleanup Act of 2024

The Legacy Mine Cleanup Act of 2024 establishes a new Office within the EPA's Land and Emergency Management division to coordinate cleanup efforts at abandoned hardrock mining sites across the U.S., including sites in Indian country and Navajo Nation uranium mine areas. The Office will annually identify priority sites for cleanup, develop best practices for remediation, and coordinate with tribes, states, and federal agencies like the Department of Energy. It specifically requires a 10-year interagency plan by 2027 to address uranium contamination on Navajo Nation lands, including funding targets and agency responsibilities. The bill does not create new EPA regulatory powers but streamlines existing cleanup coordination. It directly affects EPA operations, tribal governments, and communities near abandoned mine sites lacking responsible parties.
