Under Section 106 of the National Historic Preservation Act (the Act), federal agencies and their designees/authorized representatives must consider the impact of federal undertakings on archeological and historic resources which are listed on or eligible for the National Register of Historic Places. The Advisory Council on Historic Preservation's (a federal agency) regulations detail how the Section 106 process is carried out, and these regulations (36 CFR Part 800) were recently revised. Because agencies must consult with the Oklahoma State Historic Preservation Office (SHPO) in the review process, we provide the Review and Compliance Manual as a guide to the consultation process in Oklahoma.

In the following pages you will find answers to the most commonly asked questions about the Section 106 process, tips about how to submit project information to the SHPO, guidance on preparing documentation for determinations of National Register eligibility, and recommendations about the material to submit for assessment of the effects of federal undertakings on archeological and historic properties. Additionally, the manual contains the Advisory Council's new regulations (effective June 17, 1999), the Secretary of the Interior's Standards and Guidelines for Rehabilitation, and information about the changes in the Advisory Council's regulations.

Agencies should pay special attention to changes in the regulations concerning consultation with Tribal Historic Preservation Officers (THPO) and the public.

If there are questions about completing the Section 106 process in Oklahoma, contact the SHPO, 800 Nazih Zuhdi Drive, Oklahoma City, OK 73105 (405/521-6249).
