The CEQ is issuing this interim final rule to remove the existing implementing regulations for the National Environmental Policy Act, in response to E.O. 14154, Unleashing American Energy. Among other things, E.O. 14154 rescinds E.O. 11991, Relating to Protection and Enhancement of Environmental Quality, which amended E.O. 11514, Protection and Enhancement of Environmental Quality, and directed CEQ to promulgate regulations for implementing NEPA and required Federal agencies to comply with those regulations. E.O. 14154 also directs CEQ to issue guidance on implementing NEPA and to propose rescinding the NEPA implementing regulations. This interim final rule carries out President Trump's latter instruction. See Section II.A. As explained in Section II.B of this rule, CEQ has also concluded that it may lack authority to issue binding rules on agencies in the absence of the now-rescinded E.O. 11191. CEQ cited E.O. 11991 as authority in 1978 when it first issued its NEPA regulations. However, that Executive Order has now been rescinded, and CEQ therefore has determined that it is appropriate to remove its regulations from the Code of Federal Regulations. This interim rule is effective 11 April 2025. Comments are due by 27 March 2025. POC is Megan Healy, Principal Deputy Director for NEPA, 202-395-5750, Megan.E.Healy@ceq.eop.gov.
