Summary
The Advisory Council on Historic Preservation issued an interim final rule removing and reserving its NEPA implementing regulations at 36 CFR Part 805. The rule is effective upon Federal Register publication, with comments due 30 days after publication. ACHP explains that its NEPA procedures were adopted in 1980 to supplement CEQ’s NEPA regulations, but CEQ has since rescinded its own NEPA regulations following Executive Order 14154.
ACHP says it rarely undertakes major federal actions requiring NEPA review. The notice states that ACHP’s last NEPA document was an environmental assessment in the late 1990s for its Section 106 rulemaking, which ended in a finding of no significant impact.
The agency’s stated rationale is that Part 805 is now outdated and obsolete because it was built around CEQ regulations that no longer exist, Congress has amended NEPA since 2023, and the Supreme Court’s 2025 Seven County decision would require updates to ACHP’s procedures. ACHP says it may develop internal NEPA procedures later if needed.

ACHP NEPA Implementing Procedures
36 CFR Part 805 establishes the Advisory Council on Historic Preservation’s procedures for implementing the National Environmental Policy Act (NEPA). It explains that NEPA requires all federal agencies to evaluate environmental impacts when making decisions and to prepare detailed environmental analyses for major actions affecting the environment. These procedures supplement the broader NEPA regulations issued by the Council on Environmental Quality (CEQ), ensuring the Council properly integrates environmental considerations into its own activities and decision-making processes.
The regulation applies to various Council actions, including legislative recommendations, policy development, and regulations tied to historic preservation authorities. It also clarifies that the Council’s role in commenting on projects under Section 106 of the National Historic Preservation Act is advisory and generally excluded from separate NEPA review because the primary federal agency retains responsibility for environmental compliance. The rule outlines how environmental documents—such as environmental assessments (EAs) and environmental impact statements (EISs)—must be reviewed, carried through internal processes, and considered when evaluating proposals.
Finally, Part 805 defines how the Council determines the appropriate level of environmental review, typically requiring environmental assessments unless circumstances warrant a full EIS or a different level of review. It emphasizes coordination with other agencies and stakeholders, sometimes acting as a lead agency when appropriate, and ensures transparency by providing a point of contact for public information on NEPA compliance.
Likely Effects of Current Policy
The direct practical effect is narrow: ACHP is removing its own internal NEPA procedures, not changing Section 106 regulations or imposing new requirements on project sponsors, states, Tribes, or local governments. Because ACHP rarely acts as the agency conducting NEPA review, this is unlikely to change day-to-day permitting requirements for most infrastructure projects.
The broader significance is that another federal entity is aligning with the post-CEQ-regulations NEPA framework. The notice reinforces the administration’s view that agencies should rely more directly on the NEPA statute, recent statutory amendments, and judicial deference principles from Seven County, rather than older agency-specific procedural rules built around CEQ’s former regulations.
For infrastructure delivery, the main watch item is coordination risk. ACHP plays an important role in historic preservation policy and Section 106 consultation, so agencies may need to be clearer in their own procedures about how NEPA and historic-preservation review fit together. The change could reduce obsolete cross-references, but it may also leave more discretion and variability unless ACHP or lead agencies issue replacement internal guidance.
