Categorical Exclusion (CX) Determinations
Under the National Environmental Policy Act (NEPA)
Total number of entries 5485
Date of last update 04/11/2011
Number of new entries 104
   

:

To further transparency and openness, DOE established a policy to document and post online all CX determinations involving classes of actions listed in Appendix B to Subpart D of the DOE NEPA regulations (10 CFR Part 1021).



This database contains CX determinations required to be posted under the 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.



The 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 Act (Recovery Act or ARRA) of 2009.  Links to CX determination documents are provided.  The database will be updated approximately monthly.



See www.gc.energy.gov/NEPA/categorical_exclusion_determinations.htm for information on DOE CX procedures.  For further information on DOE’s NEPA compliance program, see www.gc.energy.gov/NEPA or email askNEPA@hq.doe.gov.
