Western Abandoned Uranium Mine Region
There are more than 100 abandoned uranium mines (AUMs) in the Western AUM Region. These mines are generally located along the Little Colorado River and Highway 89, and are in the Cameron, Coalmine Canyon, Bodaway/Gap, and Leupp Chapters.
Mines in the Western AUM Region were operated in the 1950s and 1960s by a number of different companies before being abandoned. While the Navajo Nation Abandoned Mine Lands program addressed many of the physical hazards associated with these mines, EPA and Navajo Nation EPA are working to address remaining chemical and radiological hazards that may pose a risk to community members.
Legal Agreements and Upcoming Mine Assessments
- In 2013, EPA signed a legal agreement called an Administrative Order on Consent with El Paso Natural Gas to assess 19 mine claims in western Navajo Nation. In 2017, EPA issued a modification to the Administrative Order on Consent to continue work at the 19 mines.
- In 2015, the Phase 1 Navajo Environmental Response Trust was established, which included funding for the assessment of one mine claim in the area.
- In 2016, EPA signed a legal agreement with Babbitt Ranches to assess the Section 9 Lease Abandoned Uranium Mine site.
- Also in 2016, the Phase 2 Navajo Environmental Response Trust was established, which included funding for the assessment of 13 mine claims in the area.
- In 2017, EPA signed a legal agreement with EnPro Holdings to assess eight AUMs, including two priority mines.
In the communities of Cameron, Coalmine Canyon, Bodaway/Gap, and Leupp, residents should know and participate in what EPA is doing in their community, and have a say in it. The main purpose of engaging community members is to give them the opportunity to become involved in EPA’s activities and help shape the decisions that are made affecting their community.
To further this goal, EPA developed the Western Navajo Abandoned Uranium Mine Region Community Involvement Plan with input from community members. The Community Involvement Plan is a living document to guide community members and EPA in meaningful information sharing regarding cleanup activities in the Western Abandoned Uranium Mine Region.
- Who Is the Community?
Mines in the area are located along the Little Colorado River and Highway 89, and are located in the Cameron, Coalmine Canyon, Bodaway/Gap, and Leupp Chapters. Some of the mines are located near Homesites, especially those who live near the bridge in Cameron over the Little Colorado River. Additional mines are located along the Little Colorado River south of Cameron and along Highway 89 north of Cameron. Affected community members include those who graze livestock in these areas or have vending stalls along the highway.
