Arizona Congressman Eli Crane (R-AZ02) introduced the bipartisan Legacy Mine Cleanup Act of 2025 alongside Arizona Democrats Rep. Greg Stanton (D-AZ04), Senator Mark Kelly, and Republican Senator Cynthia Lummis of Wyoming. In the proposed legislation, the Office of Mountains, Deserts, and Plains (OMDP) within the EPA, launched in 2020 under by President Donald Trump, would be codified into law.
The OMDP, which enhances coordination between federal, state, and tribal agencies in hardrock mining cleanup, would establish congressional oversight of the office as well.
According to Crane, the codification of the OMDP under this bill would:
- “Encourage the EPA to prioritize responsible mine cleanup in Arizona over green initiatives,
- Ensure proper congressional oversight of its progress,
- Bolster the OMDP’s outreach to ensure that local and Tribal authorities have a seat at the table for cleanup projects that impact their health and environment,
- Provide guardrails to keep the office’s efforts focused on mine cleanup.”
“As we work to support domestic mining of critical minerals, it’s crucial that we remain committed to doing so responsibly. The consequences of poor stewardship are detrimental for the health and safety of those living in rural Arizona, particularly on the Navajo Nation,” Rep. Crane said in a statement. “I’m proud to introduce this bipartisan legislation that would help ensure reasonable and timely cleanup and increased congressional oversight of the process.”
In a post to X, Navajo Nation President Buu Nygren publicly announced his support for the measure and thanked Rep. Crane and his co-sponsors.
“I want to thank Congressmen Eli Crane and Greg Stanton, Senators Mark Kelly and Cynthia Lummis, and all those involved in the introduction of the Legacy Mine Cleanup Act. This legislation is a critical step forward in addressing the long-standing health and environmental impacts of abandoned hardrock mines, especially on the Navajo Nation,” said Navajo Nation President Buu Nygren.
“By codifying the Office of Mountains, Deserts, and Plains at the EPA, this bill ensures Tribal nations like ours have a meaningful voice in mine cleanup efforts that directly impact our communities. We have lived with the consequences of these abandoned sites for far too long—this act represents accountability, cooperation, and real progress. Ahéheeʼ to everyone who has helped move this issue forward.”
“Abandoned hardrock mines put Arizona communities—especially Tribal nations—at a high risk of exposure to substances that are hazardous to their long-term health,” Rep. Greg Stanton said. “Our bipartisan legislation works to swiftly and responsibly mitigate this environmental threat, and makes sure Tribal and local authorities have a stronger voice in the process.”
