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.
Responsibilities for archaeology under Section 106 extend to undertakings such as construction projects and land and resource planning efforts occurring on federal lands, as well as those where federal agencies provide funding or issue licenses, permits, or approvals for actions on non-federal lands, including tribal, state, municipal, and private property.
The Advisory Council on Historic Preservation’s Section 106 Archaeology Guidance is designed to assist federal agencies in making effective management decisions about archaeological resources in completing the requirements of Section 106 of the National Historic Preservation Act (NHPA) 54 U.S.C. § 306108] and its implementing regulations, “Protection of Historic Properties” [36 CFR part 800]. To encourage both effective and efficient consideration of archaeology in planning, this guidance highlights the decision-making role of the federal agency in the Section 106 process. This document is also designed for use by State and Tribal Historic Preservation Officers (SHPOs/THPOs), Indian tribes, Native Hawaiian organizations (NHOs), and cultural resource management professionals when assisting federal agencies to meet their responsibilities under Section 106.
