The U.S. Environmental Protection Agency (EPA) and the U.S. Department
of Energy's National Renewable Energy Laboratory (NREL) are evaluating
the feasibility of developing renewable energy production on Superfund,
brownfields, and former landfill or mining sites. Superfund sites are
the most complex, uncontrolled or abandoned hazardous waste sites in
the USA identified by EPA for cleanup due to the risk they pose to
human health or the environment. Brownfields are properties at which
expansion, redevelopment, or reuse may be complicated by the presence
of contaminants.
EPA is now investing in a project that pairs
EPA's expertise on contaminated sites with the renewable energy
expertise of NREL. The project is part of the RE-Powering America's
Land initiative, which aims to decrease the amount of green space used
for development, reduce greenhouse gas emissions, and provide health
and economic benefits to local communities, including job creation.
The
project will analyze the potential development of wind, solar, or small
hydro development at 12 sites. The analysis will include determining
the best renewable energy technology for the site, the optimal location
for placement of the renewable energy technology on the site, potential
energy generating capacity, the return on the investment, and the
economic feasibility of the renewable energy projects. The 12 sites are
located in Calif., Fla., Kan., Mass., Mich., Minn., Pa., Puerto Rico,
R.I., W.Va., and Wis.
The
EPA estimates that there are approximately 490,000 sites and almost 15
million acres of potentially contaminated properties across the United
States that are tracked by EPA. This estimate includes Superfund,
Resource Conservation and Recovery Act (RCRA), Brownfields, and
abandoned mine lands.

goals have already been achieved and controls put in place to ensure
long-term protection for more than 917,000 acres across the USA.
Through coordination and partnerships among federal, state, tribal and
other government agencies, utilities, communities and the private
sector, many new renewable energy facilities can be developed on these
potentially contaminated properties.
Some of the sites under
consideration for renewable energy projects have completed cleanup
activities, while others may be in various stages of assessment or
cleanup. Renewable energy projects on these sites will be designed to
accommodate the site conditions.
In September 2008, EPA launched
the RE-Powering America's Land initiative to promote the developing of
renewable energy on potentially contaminated land and mining sites. EPA
partnered with NREL to do an initial screening to determine sites that
may be used for renewable energy projects.
