The Department of the Army and the U.S. Army Corps of Engineers (USACE) announced we are seeking comments on an interim final rule that establishes new National Environmental Policy Act (NEPA) implementing regulations at Title 33 Code of Federal Regulations (CFR) part 333 for the USACE Regulatory Program and the USACE Section 408 Program. The interim final rule became effective on July 3, 2025 for Regulatory Program permit applications and Section 408 permission requests submitted to the USACE on or after July 3, 2025. The new USACE NEPA implementing procedures at 33 CFR 333 replace the Corps Regulatory Program’s previous NEPA implementing procedures at 33 CFR 325, appendix B.
