The National Environmental Policy Act requires government agencies to assess in advance the environmental impact of certain types of their activities. Some activities require environmental assessments or environmental impact statements; others receive a "categorical exclusion" as defined in the law.

Environmental Impact Statements (EISs) and Environmental Assessments (EAs) prepared for the Office of Nuclear Energy programs are listed on the DOE web page at the following URL:  http://www.gc.energy.gov/NEPA/index.htm
