National Environmental Policy Act Information

The National Environmental Policy Act (NEPA) and its implementing procedures (10 CFR 1021) require federal agencies to integrate environmental values into their decision-making process by considering the environmental impacts of their proposed actions and reasonable alternatives for implementing those actions.

Categorical Exclusions

Categorical exclusions are classes of Departmental actions that U.S. Department of Energy (DOE) has, by regulation, determined do not individually or cumulatively have a significant effect on the environment and for which, therefore neither an environmental impact statement nor an environmental assessment is normally required. An agency's NEPA Compliance Officers determine whether particular proposed actions fit within the defined categorical exclusions.

Under DOE's NEPA regulations, absent any extraordinary circumstances related to the proposal that may affect the significance of its environmental effects, a proposed activity can be categorically excluded from further NEPA review if it falls within any of the "general" agency classes of action (such as routine administrative, financial, and personnel actions) listed in Appendix A of Subpart D or "specific" agency actions (involving, for example, construction of bench-scale research projects or actions to promote energy efficiency) listed in Appendix B.

Under a new policy announced in "NEPA Process Transparency and Openness" (October 2, 2009 memorandum from Deputy Secretary Daniel B. Poneman to Heads of Departmental Elements), each Program and Field Office (including the National Nuclear Security Administration and the Power Marketing Administrations) will document and post online all categorical exclusion determinations involving classes of actions listed in Appendix B of the Department's NEPA implementing procedures. (This policy does not require posting of categorical exclusion determinations involving classes of actions listed in Appendix A.) However, posted categorical exclusion determinations will not contain information exempt from disclosure under the Freedom of Information Act (FOIA), such as classified, trade secrets or commercial or financial information.
