Abstract
The Department of the Interior (Department or DOI) is adopting the interim final rule (IFR) published on July 3, 2025, with minor changes, as final. In the IFR, DOI provided a 30-day comment period for the public to review and make comments. This final rule addresses public comments and adopts as final the IFR, with certain substantive changes as explained herein. The IFR partially rescinded DOI's regulations implementing the National Environmental Policy Act (NEPA) and made necessary targeted updates to those provisions that were not repealed. DOI will henceforth maintain the majority of its NEPA procedures--which apply only to DOI's internal processes--in a Departmental Handbook separate from the Code of Federal Regulations (CFR).
