Protecting Historic Properties: A Citizen’s Guide to Section 106

Cultural Resources

BLM will lead the effort to prepare the environmental impact statement and resource management plan amendments, and ensure compliance with Section 106 of the National Historic Preservation Act (NHPA).

Section 106 of the NHPA requires the BLM and cooperating federal agencies to consider the effects of the agency’s undertaking on properties listed on, or eligible for, the National Register of Historic Places (which can include a diversity of archaeological, historical, and traditional tribal and cultural resources). Regulations for Protection of Historic Properties (36 Code of Federal Regulations 800) implement Section 106 and define a process for federal agencies to use in consulting with State Historic Preservation Offices (SHPOs), tribes, and other interested parties as they assess the effects of their undertakings.

BLM has initiated Section 106 consultation with 33 tribes and the Wyoming, Colorado, and Utah SHPOs. These consultations will be ongoing and solicit input regarding cultural resource concerns associated with the project. A Programmatic Agreement will be prepared to document agreement among agencies, tribes, and other consulting parties regarding the manner in which the BLM will meet its responsibilities under the NHPA. Any member of the public may self-identify to BLM as being interested in participating in the Section 106 process.

The Advisory Council on Historic Preservation has created guidance to assist the public: Protecting Historic Properties: A Citizen’s Guide to Section 106, found at www.achp.gov/work106.html.
