CEQ is responsible for developing procedures for Federal agency implementation of NEPA. These procedures were initially promulgated in 1971 as guidelines, and were then issued as regulations in 1978. In July 2020, CEQ comprehensively updated its NEPA regulations for the first time in over 40 years. The updated regulations incorporate elements of the One Federal Decision policy, codify certain case law and CEQ guidance, revise the regulations to reflect current technologies and agency practices, eliminate obsolete provisions, and improve the format and readability of the regulations.
This CEQ publication provides the text of 40 CFR parts 1500–1508, the National Environmental Policy Act of 1969, the Environmental Quality Improvement Act of 1970, Section 309 of the Clean Air Act, Executive Order 115114, and Executive Order 13807.
On January 10, 2020, CEQ issued a Notice of Proposed Rulemaking for public comment through March 10, 2020, and conducted public hearings in Denver, Colorado, on February 11 and in Washington DC on February 25. Public comments are available at https://www.regulations.gov/docket?D=CEQ-2019-0003.
