Section 106 Review

Under Section 106 of the National Historic Preservation Act (NHPA), federal agencies must consider the effect of their actions on historic properties and provide the federal Advisory Council on Historic Preservation (ACHP) the opportunity to comment on proposed actions. Each State Historic Preservation Office (SHPO) plays a critical role in the Section 106 process. As set out in Sections 101(b)(3) and 101(d) of the NHPA, they “consult, advise, and assist” federal agencies in carrying out the agency’s Section 106 responsibilities. Under Section 101(b)(9)(a) of the NHPA, SHPOs have a responsibility to “consult with appropriate Federal agencies . . . on Federal undertakings that may affect historic property.” Pursuant to these authorities, SHPOs annually review more than 110,000 federal undertakings. While the SHPO participates in the Section 106 consultation process, it is the federal agency that bears the responsibility for initiating various steps in the process. Although the federal agency may use the services of applicants, consultants, or designees to prepare information, analyses and recommendations, the federal agency remains legally responsible for all required findings and determinations.

To successfully complete Section 106 review, federal agencies must:

  • gather information to decide which properties in the project area are listed in or eligible for listing in the National Register of Historic Places;

  • if so, determine how these historic properties might be affected;

  • explore alternatives to avoid or reduce harm to historic properties; and

  • reach agreement with the SHPO (and the ACHP in some cases) on measures to deal with any adverse effects or obtain advisory comments from the ACHP, which are sent to the head of the agency.

When historic properties will be harmed, Section 106 review usually ends with a legally binding agreement that establishes how the Federal agency will address the adverse effects. In the few cases where this does not occur, and the ACHP issues advisory comments, the head of the Federal agency must consider the comments in making a final decision.

Initiate Review

To initiate Section 106 review in Missouri, the federal agency or its agent/consultant must submit a Section 106 Project Information Form (see below). For guidance on finding and hiring a consultant, click here. Section 106 forms, instructions, and regulations are available below as downloadable PDF files. The editable forms cannot be submitted online, but are offered as a convenient way to fill out and print the document. The completed document must then be signed and mailed in together with the required supplemental material.

The department has changed all fill-in forms to PDF fill-in. You will be able to save and reuse these PDF forms. However, you will need Adobe Acrobat Reader 7 or higher to save the PDF fill-in form. Also, at this time SHPO does not accept digital signatures. If your Acrobat Reader prompts you to use one, we ask that you don't.
