Advisory Council on Historic Preservation

The Section 106 regulations, “Protection of Historic Properties,” (36 CFR Part 800), offer program alternatives through which agencies can tailor the Section 106 review process for a group of undertakings or an entire program that may affect historic properties. This chart compares and contrasts the five program alternatives in terms of their objectives; roles and responsibilities for agency, ACHP, other stakeholders, and the public; approval action; and time frames for development.
