Commonly Asked Questions about Section 106 and the State Register Act
What is "Section 106" review?
Section 106 of the National Historic Preservation Act requires Federal agencies to take historic properties into account in all projects in which agencies are involved. The Act requires agencies to initiate consultation not only with the state historic preservation officer (SHPO) but also with tribal representatives, local groups and governmental entities. In its simplest form, an agency is required to identify and evaluate the National Register eligibility of cultural resources within the area affected by a project; determine how a project will affect eligible or listed properties; and seek alternatives to avoid, minimize and mitigate effects to such properties. The role of the SHPO is to advise and comment upon an agency’s determinations at each stage of this process. The SHPO does not have the authority to stop a project, but it is entitled to obtain from agencies sufficient information upon which to comment.
