National Environmental Policy Act
National Environmental Policy Act
The National Environmental Policy Act (NEPA) of 1969 requires all federal agencies to consider the environmental impacts of their proposed actions and the reasonable alternatives for implementing those actions during the decision making process. The Y-12 National Security Complex follows the Council on Environmental Quality regulations (40 CFR 1500-1508) and the Department of Energy’s Implementing Procedures (10 CFR 1021).
There are three types of NEPA documents, an Environmental Impact Statement (EIS), and Environmental Assessment (EA), and a Categorical Exclusion (CX) Determination.
Categorical exclusions are classes of DOE actions that DOE has, by regulation, determined do not individually or cumulatively have a significant effect on the environment and for which, therefore, neither an EIS nor an EA is normally required.
In accordance with DOE’s transparency and openness policy, Y-12 National Security Complex posts on this page documentation of CX determinations involving classes of actions listed in Appendix B to Subpart D of DOE’s Implementing Procedures, 10 CFR Part 1021.
For further information, please contact the Y-12 Site Office NEPA Compliance Officer, Pamela Gorman, 865.576.9903.
