The Advisory Council on Historic Preservation has voted to significantly weaken Section 106 of the National Historic Preservation Act (NHPA), a key regulation that requires federal agencies to consult with tribes, local governments, and the public before proceeding with federally funded or permitted projects that may impact historic sites. Enacted in 1966 to protect historic places amid widespread urban renewal and highway construction, Section 106 established a consultation process involving state and tribal preservation officers and other stakeholders to identify and mitigate adverse effects on historic properties.

The proposed changes, initiated under the Trump administration’s directive to review regulations, would limit the ability of tribes, local governments, and the public to participate meaningfully in the review process. Tribal and preservation leaders expressed surprise and concern, warning that the revisions undermine collaborative decision-making and threaten the preservation of culturally significant sites. While the Advisory Council approved the changes, they are currently under review by the Office of Information and Regulatory Affairs before final implementation. Critics fear these revisions could accelerate damage to historic and cultural resources by reducing oversight and consultation opportunities.
