July 2026 Updates

ACHP Advances Sweeping Revisions to the Section 106 Regulations

Late on Friday, July 17, 2026, the Advisory Council on Historic Preservation provided Council members with sweeping proposed revisions to the regulations implementing Section 106 of the National Historic Preservation Act at 36 C.F.R. Part 800. Council members were asked to review the proposal and cast their votes through an unassembled meeting by 5:00 p.m. on Friday, July 24.

The vote is not to adopt a final rule. It will determine whether the proposal advances as a Notice of Proposed Rulemaking. If approved, the proposal would proceed through additional federal review before publication for public comment.

Section 106 is one of the primary federal processes Tribal Nations and Tribal Historic Preservation Officers use to ensure that sacred places, ancestral lands, burial places, cultural landscapes, historic properties, and associated traditions and practices are considered before federal agencies make decisions that may affect them.

These proposed regulations are not a technical adjustment. They would substantially restructure the Section 106 process, weaken the role of Tribal Nations and THPOs, and place considerably greater control with the federal agencies responsible for carrying out, funding, licensing, permitting, or approving federal undertakings.

The ACHP’s proposed regulations are an affront to Tribal sovereignty. Any effort to diminish our voice or disregard the places, traditions, and practices we hold sacred is egregious and represents a violation of the federal government’s trust and treaty responsibilities that is neither morally nor ethically defensible.” - Ira L. Matt (Séliš), NATHPO Executive Director, Indigenous Diplomacy and Federal Relations

NATHPO is deeply concerned that changes of this magnitude are being advanced without giving Tribal Nations a meaningful opportunity to review the proposal, understand its consequences, consult with their leadership and legal counsel, and make their voices heard before the Council acts.

A Departure from the Process Approved in June. The accelerated vote departs from the process approved by the ACHP at its June 4, 2026, business meeting. At that meeting, the Council directed ACHP leadership and staff to develop a schedule, including milestones and deliverables, for revising the Section 106 regulations within 30 days. Council members were also provided 60 days to submit additional substantive feedback and proposed changes.

That schedule was not provided before the proposed regulations and voting materials were circulated. Instead, Council members received a substantially completed rewrite and approximately one week to review and vote on it.

Changes of this magnitude should be considered through a transparent and deliberative process that includes meaningful Tribal consultation and provides Tribal Nations sufficient time to evaluate the legal, cultural, governmental, and practical consequences.

Principal Concerns. NATHPO is continuing its legal and policy review. The concerns below are preliminary and do not represent an exhaustive analysis of the proposal.

Narrowing what qualifies as an undertaking. The proposal would exclude certain state, Tribal, and local actions carried out under delegated federal authority. Other provisions would provide additional grounds for agencies to conclude that federal funding, approval, assistance, or involvement does not trigger Section 106 review. When an activity is treated as outside the definition of an undertaking, the agency generally has no obligation under Section 106 to identify historic properties, consult with affected Tribal Nations, assess effects, or consider ways to avoid or address harm.

Excluding certain natural and cultural places from the definition of historic property. The proposal would generally require a place to be geographically compact and connected to tangible human improvements or specific human activities. It further states that “noncompact, unimproved natural features such as mountains, valleys, bodies of water, or landscapes, including ethnographic landscapes, do not qualify as property” for Section 106 purposes. This could exclude places whose significance arises from continuing religious and cultural practice, subsistence, oral tradition, place names, cultural responsibility, ceremony, and enduring relationships among Tribal people, ancestors, land, water, plants, and animals.

Not every Tribal cultural place can be reduced to a tightly bounded parcel or identified through buildings, archaeological deposits, or other visible physical remains. Some places are understood through relationships among multiple locations, waterways, mountains, gathering areas, travel routes, viewsheds, and ceremonial settings. The absence of tangible human improvements does not make those places less sacred, less culturally significant, or less deserving of consideration.

Reducing Tribal and THPO participation. The draft removes provisions that give Tribes a reasonable opportunity to identify concerns, advise agencies on the identification and evaluation of historic properties, explain how an undertaking may affect those properties, and participate in resolving adverse effects. It also reduces THPO involvement at several stages, shifts more findings and decisions to the agency official, and moves the role of consulting parties toward commenting on an agency-prepared report.

Consultation is not meaningful when a Tribe is presented with a substantially completed agency analysis and given only a limited opportunity to respond. It must begin early enough for Tribal knowledge, concerns, and recommendations to influence identification, evaluation, effects analysis, project alternatives, and the resolution of harm.

Removing recognition of Tribal expertise and legal context. The draft deletes language recognizing the special expertise of Indian Tribes in assessing the eligibility of properties of religious and cultural significance. It also removes express references to the government-to-government relationship, Tribal sovereignty, treaty rights, and the fact that culturally significant places are often located on ancestral, aboriginal, or ceded lands.

Tribal Nations are sovereign governments, not members of the general public or sources of supplemental cultural information. General assurances that the regulations do not alter Tribal sovereignty or treaty rights do not resolve the concern if the operative provisions reduce Tribal involvement or disregard Tribal expertise.

Narrowing the effects considered. The proposal would remove references to indirect and cumulative effects and limit adverse effects to “only those reasonably foreseeable effects that have a reasonably close causal relationship to the undertaking.” It would also remove specific recognition of changes to a property’s use or setting and the introduction of visual, atmospheric, or audible elements as potential adverse effects.

These changes are especially significant for sacred places and cultural landscapes. A place may be harmed through changes to access, setting, privacy, sound, visibility, water, vegetation, ceremonial conditions, or the ability of Tribal citizens to continue religious and cultural practices. Those effects can be profound even when a project does not excavate, demolish, or physically alter the place itself.

Expanding agency control over the process. The draft provides that an agency official “may alter any deadline in this part, to be shorter or longer.” Agencies would also have greater control over the area of potential effects, the scope of identification, agency findings, and the consideration of comments from consulting parties.

The proposal would allow an agency to prepare a consolidated Section 106 report containing its identification, effects analysis, and proposed response before circulating that analysis for comment. This risks transforming consultation from a collaborative planning process into an opportunity to react to conclusions the agency has largely developed on its own.

The draft would also allow an agency official to treat matters addressed only briefly or left unaddressed as intentionally omitted because the agency considered them “comparatively unimportant or frivolous.” That is especially concerning where an agency does not understand or gives insufficient weight to Tribal knowledge, cultural values, or effects identified by a Tribe.

Replacing negotiated outcomes with agency decisions. The proposal would move away from memoranda of agreement and toward agency-issued memoranda of decision. The agency could determine how it will address effects or conclude that “other considerations outweigh” historic preservation concerns. This would allow the agency to consult, decline to secure agreement on how adverse effects will be addressed, and document its own decision to proceed.

Expanding exemptions and procedural off-ramps. The proposal encourages broader use of exemptions and other mechanisms through which categories of undertakings or programs could avoid full Section 106 review. The accompanying notice describes an intent to create additional “on- and off-ramps” and make Section 106 exemptions function more like categorical exclusions under the National Environmental Policy Act.

Section 106 and NEPA serve different statutory purposes. A determination that an activity has no significant environmental effect under NEPA does not establish that it cannot affect a historic property or a place of religious and cultural significance to a Tribal Nation.

Making public participation discretionary. The proposal characterizes public comment as “optional, not mandatory” and would largely leave the decision whether to seek public input to the agency official. This would reduce opportunities for affected communities, local governments, preservation organizations, and members of the public to identify properties, raise concerns, and inform agency decisions.

Taken together, these changes could transform Section 106 from a collaborative planning process into an agency-directed review followed by an opportunity for others to comment.

Section 106 Supports Better Federal Decisions. Section 106 does not prohibit federal projects. It requires federal agencies to make informed decisions before proceeding.

Tribal Nations and THPOs regularly work with agencies and project proponents to advance infrastructure, energy, housing, transportation, broadband, conservation, emergency response, and other public priorities while protecting places that cannot be replaced.

When initiated early and supported by adequate federal staffing, Section 106 helps agencies identify important places, recognize project risks, evaluate reasonable alternatives, avoid preventable conflict, and address concerns before decisions become difficult or costly to change.

Many delays attributed to Section 106 instead result from poor planning, incomplete identification efforts, inadequate agency staffing, late consultation, or the treatment of consultation as a final compliance step. Weakening consultation does not correct those failures. It may allow unresolved legal, cultural, and project risks to grow until they become more costly, contentious, or irreversible.

Access to the Proposed Materials. Because NATHPO is a member of the ACHP, we have been advised not to publicly share the draft regulations or related rulemaking materials while the ACHP considers them pre-decisional and deliberative.

What Tribal Nations Can Do Now. Tribal Nations and THPOs should begin briefing Tribal leadership, legal counsel, cultural resource staff, and other appropriate offices regarding the proposed revisions.

NATHPO encourages Tribal Nations and THPOs to:

  • review how the proposal may affect consultation rights, government-to-government engagement, and THPO authorities;
  • identify sacred places, burial places, cultural landscapes, treaty-protected rights, and continuing traditional practices that may be placed at greater risk;
  • document examples showing how early and meaningful consultation improved federal decisions, avoided harm, or reduced project conflict;
  • document examples in which late, incomplete, or inadequate consultation caused harm, delay, or conflict;
  • coordinate with other Tribal Nations, intertribal organizations, legal counsel, and preservation partners;
  • contact congressional offices and appropriate state officials to explain the potential effects of the proposal;
  • participate in NATHPO’s Tribal forums and other engagement opportunities; and
  • prepare to participate in any formal rulemaking and public-comment process.

These steps will help ensure that Tribal Nations are prepared to evaluate the proposal, communicate their concerns, and make their voices heard as the process moves forward.

Tribal Forums. NATHPO is convening national Tribal forums to provide information, hear directly from Tribal Nations and THPOs, and ensure that Tribal concerns guide NATHPO’s response. The forums are open to Tribal leaders, THPOs, Tribal legal counsel, cultural resource personnel, and other Tribal government employees.

July 21, 2026, at 1:00 p.m. Pacific Time. The July 21 forum will provide a high-level overview of the proposed revisions and their potential effects on Tribal participation in the Section 106 process.

July 28, 2026, at 11:00 a.m. Pacific Time. The July 28 forum will provide updated information, continue the discussion, and offer another opportunity for Tribal Nations and THPOs to provide guidance.

NATHPO also plans to facilitate a separate discussion for Tribal legal offices so Tribal governments and their counsel are prepared to evaluate the legal and governmental implications of the proposal and participate in any formal rulemaking process.

NATHPO’s Commitment. NATHPO will continue working to ensure that Tribal sovereignty, the federal trust responsibility, treaty responsibilities, and the rights of Indian Tribes are not disregarded in this process.

The federal preservation system cannot be weakened at the expense of meaningful Tribal participation or the places and practices Tribal Nations have carried forward since time immemorial.

Any revision to 36 C.F.R. Part 800 must improve federal accountability and support better federal decision-making. It must not achieve speed by diminishing Tribal voices, narrowing federal responsibilities, or removing sacred and culturally significant places from meaningful consideration.
