Montana Historical Society

Big Sky. Big Land. Big History.

Thank you for your careful consideration of Montana’s cultural resources!

The Montana State Historic Preservation office provides assistance to private citizens, local governments, private organizations, and both State and Federal Government Agencies partaking in projects subject to Section 106 of the National Historic Preservation Act (NHPA) and Montana State Antiquities Act.

MT SHPO consults on projects subject to historic preservation laws to ensure federal and state projects do not carelessly destroy cultural resources. Projects include landscape modification (e.g., logging, mining, prescribed burns), construction, rehabilitation, demolition, licenses, permits, transfer of federal property, etc.

Any undertaking on Federal Land, using Federal funds, or requiring a Federal permit must comply with Section 106 of the NHPA. Any project on State Land must comply with the Montana State Antiquity Act.

How the Advisory Council on Historic Preservation (ACHP) Can Help

Whether or not the ACHP becomes involved in consultation, you may contact the ACHP to express your views or to request guidance, advice, or technical assistance. Regardless of the scale of the project or the magnitude of its effects, the ACHP is available to assist with dispute resolution and to advise on the Section 106 review process for Federal undertakings.

If you suspect Federal involvement, but have been unable to verify it, or if you believe the Federal agency or one of the other participants in review (including the Montana SHPO) has not fulfilled its responsibilities under the Section 106 regulations, you can ask the ACHP to investigate. In either case, be as specific as possible and try to have the following information available:

  • the name of the responsible Federal agency and how it is involved
  • a description of the project
  • the historic properties involved
  • a clear statement of your concerns about the project and its effect on historic properties
