EPA is recognizing federal facilities for their efforts to reduce the environmental impacts of facilities across the country. As part of the Federal Green Challenge (FGC), more than 400 federal facilities representing nearly 1.6 million federal employees are leading by example by taking steps to reduce the federal government's environmental impact in 2013, resulting in an estimated cost savings of more than $42 million to U.S. taxpayers. This year's Overall Achievement winner is The National Benefits Center, U.S. Citizenship and Immigration Services, Department of Homeland Security (DHS), Lee's Summit, Mo. Additional winners by target areas include DOE, DOD, and DOI facilities.
