Regulations at 10 CFR part 1021 are procedures that the Department of Energy (DOE) follows to comply with section 102(2) of the National Environmental Policy Act (NEPA) of 1969 (42 U.S.C. 4332(2)) and the Council on Environmental Quality (CEQ) regulations for implementing the procedural provisions of NEPA (40 CFR parts 1500-1508). This part supplements, and is to be used in conjunction with, the CEQ regulations. It is DOE's policy to follow the letter and spirit of NEPA; comply fully with the CEQ Regulations; and apply the NEPA review process early in the planning stages for DOE proposals.

DOE's NEPA regulations were revised, effective January 4, 2021, to update CX B5.7, and remove CX B5.8 and classes of action C13, D8, and D9. These changes relate to natural gas export authorizations. The changes are not reflected in the file linked below but are included in the current version of the electronic Code of Federal Regulations.
