Ecology and Environment, Inc., Plays Key Role in First Large-Scale Solar Energy Project on U.S. Public Lands in Nevada

LANCASTER, N.Y., October 20, 2010 – Ecology and Environment, Inc., (E & E) (NASDAQ: EEI) is proud to announce its involvement in the Silver State North Solar Project, the first large-scale solar energy project on U.S. Public Lands in Nevada. The First Solar, Inc. project was approved by Secretary of the Interior, Ken Salazar, yesterday. This is the second landmark, large-scale solar fast-track project to obtain Department of the Interior (DOI) approval in recent days in which E & E has played a key role providing permitting, environmental impact assessment expertise and coordinating the public involvement process.

“Silver State is one of several renewable energy projects in the pipeline that will help Nevada and the nation create jobs as we build a clean energy economy,” Secretary Salazar said in signing the Record of Decision. “This project will provide renewable energy that will help meet our nation’s growing demand as we strive to become energy independent.”

E & E prepared the precedent-setting environmental impact statement (EIS) for the 50-megawatt (MWAC) 60 (MWDC) solar facility and associated infrastructure, which will be built in the Ivanpah Valley, 40 miles south of Las Vegas. E & E worked collaboratively with the Bureau of Land Management (BLM) Las Vegas Field Office on the EIS, which analyzed environmental impacts of project construction and operation on several key resource areas, including threatened and endangered species, recreation, and hydrology; and identified appropriate mitigation measures to reduce project impacts. E & E engaged all project stakeholders and conducted well-attended public scoping meetings.

The Silver State North Solar Project is expected to generate enough electricity to power approximately 15,000 homes, create 300 construction jobs, and generate $250,000 in annual property tax revenue for Clark County, NV.

BLM Director, Bob Abbey, noted the key role public involvement played in the project’s approval. “The BLM is proud to play a major role in our nation’s quest to capture more renewable energy resources here at home,” Abbey said. “Through wise planning and engagement with local communities and stakeholders, we can support large-scale solar development on public lands while protecting valuable natural and cultural resources. If we are smart from the start, we can capture America’s renewable energy resources in the right way and the right places.”

“DOI approval of these pivotal large-scale solar projects on U.S. Public Lands is a significant step forward in advancing a clean energy economy and we are proud to play a role in making these projects a reality,” said E & E president and CEO Kevin Neumaier. “Silver State North brings Nevada one step closer to its goal of a 25 percent Renewable Portfolio Standard by 2025, and sends a clear message that standards and benchmarks like Nevada’s are achievable when energy companies, agencies, and stakeholders work collaboratively to advance environmentally sound projects.”

E & E has 40 years of global energy project experience and has been at the forefront of solar, wind and other renewable energy development. E & E has completed hundreds of renewable energy projects bringing thousands of megawatts of solar, wind, geothermal and ocean energy power to the grid.
