National Environmental Policy Act (NEPA)

NEPA Information

The National Environmental Policy Act (NEPA) and its implementing procedures 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. All work conducted at the NNSS must first be evaluated for compliance with the NEPA. Activities must be previously analyzed in an Environmental Impact Statement, Environmental Assessment, or in 10 CFR Part 1021 DOE NEPA Implementing Procedures.
