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 made wholesale revisions to the NEPA regulations for the first time in more than 40 years. CEQ is now engaged in a comprehensive review of the 2020 rule pursuant to E.O. 13990 (January 20, 2021). In its regulatory agenda, CEQ announced a phased approach to amending the NEPA regulations.
CEQ issued an Interim Final Rule on June 29, 2021, which extended the deadline by two years (to September 14, 2023) for Federal agencies to develop or update their NEPA implementing procedures to conform to the CEQ regulations.
On April 20, 2022, CEQ issued the Phase 1 Final Rule. The rule finalizes a narrow set of changes to generally restore regulatory provisions that were in effect for decades before the 2020 rule modified them for the first time. The final rule changes better align the NEPA regulations with CEQ and agency expertise, as well as NEPA’s statutory goals and purpose of promoting sound decisions informed by science.
