Note: Not all documents may be available at this time. EPA continues to update its website to enhance public access to Superfund-related information.
As part of EPA's commitment to finding innovative and effective solutions to the potential threats abandoned mine lands pose to human health and the environment, significant attention is being focused on potential future uses of these lands, and the economic, environmental, and social impact that reuse can provide. EPA recognizes that supporting reuse may serve as a catalyst for expediting environmental risk reduction. EPA's Superfund Redevelopment Program page provides additional information.

EPA has placed national priority on showcasing opportunities for the development of clean and renewable energy projects on contaminated lands. As part of this effort, EPA is working to leverage these opportunities into actual renewable energy projects for communities across the country.
EPA’s Abandoned Mine Lands Team (AMLT) has actively provided communities with technical support and resources to explore innovative reuse opportunities available at former mine lands. EPA works in partnership with EPA Regional offices, local communities and other mine site stakeholders to clarify EPA's interests at former mine lands and to address potential obstacles to innovative reuse of these sites. In addition the AMLT works in close coordination with EPA's RE-Powering America's Lands Initiative. EPA’s RE-Powering America's Lands Initiative identifies Brownfields, RCRA, Superfund and mining sites for their wind, solar and biomass development potential and provides technical resources for communities, developers, industry, local governments or other stakeholders interested in reusing these sites for renewable energy development.
The 2015 Fact Sheet: Renewable Energy on Mine Sites (PDF)(4 pp, 1.1 MB) highlights ongoing and planned renewable energy projects at mining sites.
Examples of Site Reuse Activities Involving Alternative Energy
Renewable energy projects are already in place at hardrock and coal mining sites. These energy projects are powering cleanup activities and generating electricity sold to local utilities.
- Molycorp, Inc. (Questa, NM): A 1-megawatt concentrated photovoltaic (CPV) solar facility sits on 20 acres of mine tailing at the Molycorp, Inc. site.
- Case Study (PDF) (16 pp, 6.8 MB)
- Summitville Mine (Rio Grande County, CO): A 32-kilowatt micro-hydroelectric power plant operates seasonally and supplies electricity to help power on site cleanup activities.
Renewable Energy Feasibility Assessments at Mine Sites
Through direct technical and analytic support, the EPA AMLT is working with Regional offices to help site stakeholders evaluate mining sites for their renewable energy development potential. The following reports highlight sites where these activities have taken place with AMLT support:
- Iron King Mine – Humboldt Smelter (PDF) (54 pp, 18.6 MB), Dewey-Humboldt, AZ
- ASARCO Mission Mine (PDF) (18 pp, 1.1 MB), Sahuarita, AZ
In addition, the AMLT has provided support to EPA’s Re-Power Initiative, which has awarded grants for the National Renewable Energy Lab to evaluate the feasibility of developing renewable energy production on Superfund, Brownfields, and former landfill or mining sites.
