RE-Powering America's Land:	EastHeiena, Montana

Evaluating the Feasibility of Siting Renewable Energy Production
on Potentially Contaminated Land

Feasibility Studies to RE-Power Communities

The U.S. Environmental Protection Agency's RE-Powering America's Land initiative
encourages renewable energy development on current and formerly contaminated
land and mine sites when it is aligned with the community's vision for the site. EPA
and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL)
are collaborating on a project to evaluate the feasibility of siting renewable energy
production on potentially contaminated sites.This effort pairs EPA's expertise on
contaminated sites with NREL's expertise in renewable energy. The feasibility studies
will provide site owners and communities with a realistic and achievable plan for
putting renewable energy on a given site.

Site Description

From 1888 until 2001, the American Smelting and Refining Company (ASARCO)
operated a lead and zinc smelter in East Helena, Montana. The ASARCO site was
added to EPA's Superfund National Priorities List in 1983 due to extensive soil and
groundwater contamination. The bankruptcy reorganization of ASARCO in 2009
placed more than 1,500 acres into the hands of the Montana Environmental Trust
Group (METG), which is responsible primarily for remediating the 130-acre plant site
and the groundwater contamination that has migrated to the City of East Helena.

Community Goals

Given current site conditions, renewable energy development may be the only
viable reuse for these properties. The large size of the property, adjacent utilities, and
its location near forest and farmland give the site potential for siting of a biorefinery,
biopower, or geothermal facility on the former plant site in East Helena. After more
than 100 years of smelting history, redevelopment with renewable energy could
redefine the character of the community of East Helena, creating jobs and taxable
value for future generations.

Feasibility Study: Biopower or Geothermal

EPA and NREL are collaborating to conduct a study on the potential for biopower or geothermal potential on the ASARCO
Superfund Site. The feasibility study will evaluate the technical and economic opportunities and challenges at the site. It will:

¦	Provide a preliminary analysis of the viability of the site;

¦	Assess biopower or geothermal resource potential;

¦	Identify possible facility type, size, and location; and

¦	Review the economics of the proposed facility.
