National Environmental Policy Act (NEPA) Categorical Exclusion Determinations
To further transparency and openness in its implementation of the National Environmental Policy Act (NEPA), the Department of Energy has established a policy with regard to the online posting of certain categorical exclusion determinations. Under the policy, each program and field office will document and post online all categorical exclusion (CX) determinations involving classes of actions listed in Appendix B to Subpart D of the Department's NEPA regulations, 10 CFR Part 1021 (PDF 156 KB). This page lists the NEPA categorical exclusion determinations for the DOE's Office of Energy Efficiency and Renewable Energy.
Visit the DOE NEPA site to learn more. You can also read the Golden Field Office's NEPA categorical exclusion determinations at the site's Reading Room.
