Welcome to the Advisory Council on Historic Preservation's (ACHP) Section 106 Archaeology Guidance. The Advisory Council on Historic Preservation’s (ACHP) primary involvement with archaeology is through Section 106 review. It has been estimated that more than 90 percent of the archaeological excavations conducted in the United States are done so pursuant to Section 106 of the NHPA.
Archaeology under Section 106
Archaeological sites are identified and evaluated under Section 106 by federal agencies for their eligibility for listing in the National Register. Through consultation with stakeholders, such as State and Tribal Historic Preservation Officers, Indian tribes, and Native Hawaiian organizations, federal agencies take into account the effects of their undertakings on eligible or listed archaeological sites.
