State Historic Preservation Program.
State Historic Preservation Program. The State Historic Preservation Program is the program established by each State and approved by the Secretary of Interior for the purpose of carrying out the provisions of the National Historic Preservation Act of 1966, as amended, and related laws and regulations. Such program shall be approved by the Secretary before the State may nominate properties to the National Register. Any State Historic Preservation Program in effect under prior authority of law before December 12, 1980, shall be treated as an approved program until the Secretary approves a program submitted by the State for purposes of the Amendments or December 12, 1983, unless the Secretary chooses to rescind such approval because of program deficiencies.
