Historic Preservation
Section 106

Under Section 106 of the National Historic Preservation Act, 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. The State Historic Preservation Office (SHPO) within the Department of Natural Resources plays an important role in Section 106 review.

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.

Once the responsible federal agency has determined that an action is an "undertaking," there are three basic steps in 106 consultation. First, the agency must determine whether "historic properties" are present in the project area. If historic properties are present, the agency must consult with the SHPO and other interested parties to determine whether the proposed undertaking will have an "effect" on the historic properties. If the effect will be adverse, the agency must notify the ACHP, and must consult with the SHPO and interested parties to discuss ways to avoid or mitigate damage to the historic properties.

For more detailed information on Section 106, you can check the ACHP website. The site contains the complete text of the revised 106 regulations and a handy Citizen's Guide to Section 106 Review that explains the process and the citizen's role in the process.

To initiate Section 106 review in Missouri, the federal agency or its agent/consultant must submit a Section 106 Project Information Form. 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 (or hand delivered).

Professional archaeologists or architectural historians complete the Section 106 Survey Memo Form to report survey results.
