Kelly's Legacy Mine Cleanup Act passed the Senate unanimously last Congress
This week, Senators Mark Kelly (D-AZ) and Cynthia Lummis (R-WY) reintroduced the Legacy Mine Cleanup Act, bipartisan, bicameral legislation that would cut bureaucratic red tape and hold the federal government accountable for better coordinating efforts to clean up abandoned uranium, copper, gold, and other hardrock mines that continue to pose environmental and public health risks.
The Government Accountability Office estimates there are approximately 140,000 abandoned hardrock mines in the United States, largely in the West. Unsecured mine tunnels, toxic waste piles, and other hazards, known as mine features, are found at abandoned hardrock mines across federal and nonfederal lands. Kelly and Lummis' legislation would establish the Environmental Protection Agency's Office of Mountains, Deserts, and Plains (OMDP) to help accelerate cleanup of abandoned mine sites by implementing best practices, improving coordination with state and Tribal partners, and maintaining a list of mine sites prioritized for cleanup.
"In Arizona, abandoned uranium mines continue to threaten the health of our families, our land, and our water," said Kelly. "By cutting red tape, strengthening accountability, and improving coordination, we can accelerate cleanups and protect communities, especially tribal nations that have carried this burden for far too long."
"Protecting Wyoming and the west's treasured landscapes requires moving beyond Washington's typical one-size-fits-all mentality," said Lummis. "We need region-specific strategies that respect our western communities and the unique challenges we face. I'm pleased to again work with Senator Kelly to give this important office permanent standing so it can build meaningful partnerships with states, tribes, and local stakeholders."
Specifically, the Legacy Mine Cleanup Act would:
Background:
The Legacy Mine Cleanup Act builds on Kelly's broader efforts to accelerate the cleanup of abandoned mines. Last year, Kelly's Good Samaritan Remediation of Abandoned Hardrock Mines Act, bipartisan, bicameral legislation to cut red tape and make it easier for "Good Samaritans" such as state agencies, nonprofits, and other groups to clean up and improve water quality around abandoned mines, was signed into law. Kelly has also secured funding for cleanup of abandoned uranium mines on the Navajo Nation, championed legislation to support innovative paths to cleanup, and repeatedly raised these issues with administration officials.
