On February 19, 2025, the Council on Environmental Quality (CEQ) issued guidance through a memorandum for heads of Federal departments and agencies on the implementation of the National Environmental Policy Act (NEPA). The guidance, consistent with Executive Order (E.O.) 14154, Unleashing American Energy, 90 Fed. Reg. 8353 (Jan. 29, 2025), requires agencies to update their implementing NEPA regulations to expedite permitting approvals and for consistency with NEPA as amended by the Fiscal Responsibility Act of 2023 (Public Law 118-5), including the deadlines established in NEPA. In accordance with CEQ’s guidance, agencies are required to complete the revision of their procedures no later than 12 months after the date of this CEQ memorandum. This proposal is for the EPA to update the implementing NEPA regulations to be consistent with the text of NEPA, E.O. 14154, and CEQ’s guidance. Examples of EPA actions subject to NEPA include the award of wastewater treatment construction grants under Title II of the Clean Water Act, EPA’s issuance of new source National Pollutant Discharge Elimination System (NPDES) permits under section 402 of the Clean Water Act, and certain research and development.
