54 U.S.C. § 302302 — Program evaluation

(a) When evaluation must happen. At least once every four years after a State program is approved under section 302301 of this title, the Secretary — working with the Advisory Council on Historic Preservation and the State Historic Preservation Officer — must evaluate the program to check that it still matches this division. (b) Disapproving a program. If the Secretary decides a major part of a State program does not match this division, the Secretary must disapprove the program and pause contracts or cooperative agreements with the State and its Officer. That pause lasts until the program matches this division again — unless the Secretary decides the program will become consistent within a reasonable time. (c) Oversight. The Secretary, working with State Historic Preservation Officers, must set up ways to oversee State programs that check consistency and quality without creating unnecessary extra review work for the Officers. (d) State fiscal audit and management system. (1) A State can substitute its own system of financial audits and management for the comparable Federal system, if the Secretary allows it. To qualify, the State's system must keep accountability standards substantially similar to the Federal ones and must include independent professional peer review. (2) The Secretary may run periodic financial audits of approved State programs as needed, and must make sure the programs meet the required accountability standards.
