* The regulations define the term "THPO" as those tribes that have assumed SHPO responsibilities on their tribal lands and have been certified pursuant to Section 101(d)(2) of the NHPA. Nevertheless, remember that tribes that have not been so certified have the same consultation and concurrence rights as THPOs when the undertaking takes place, or affects historic properties, on their tribal lands. The practical difference is that during such undertakings, THPOs would be consulted in lieu of the SHPO, while non-certified tribes would be consulted in addition to the SHPO.
