Categorical Exclusion Determinations

You are here

To further transparency and openness in its implementation of the NEPA process, DOE established a policy and, subsequently, requirements under the Department’s NEPA regulations (10 CFR Part 1021) and NEPA Order (DOE Order 451.1B) to document and post online its categorical exclusion (CX) determinations involving classes of actions listed in Appendix B to Subpart D of 10 CFR Part 1021.
