To further transparency and openness in its implementation of the NEPA process, DOE has established a policy to document and post online its 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.

This page contains links (below) to pages on this website and other DOE Program, Field, or Site Office websites containing the CX determinations required to be posted under this policy, and also some for which documentation and posting are optional, i.e., determinations involving classes of actions listed in Appendix A or made before the policy's effective date of November 2, 2009. You may browse the determinations posted on each of the websites at the links below, or search a comprehensive CX Determination Database (CX Database).

We established the comprehensive database to enhance the utility of DOE's CX posting initiative. The CX database may be searched by state, CX applied, date range, DOE Program, Field, or Site Office, keyword, and whether the CX determination is for a project related to the American Recovery and Reinvestment (Recovery Act or ARRA) Act of 2009. Links to the CX determination documents are provided. The CX database will be updated approximately monthly.
