The words “historic property” are substituted for “property included in or eligible for inclusion in the National Register” because of the definition of “historic property” in section 300308 of the new title. The words “to document a decision pursuant to this section” are substituted for “pursuant to such section” for clarity. The language was not intended to limit agency authority to delegate responsibilities under section 106 of the National Historic Preservation Act (Public Law 89–665, 80 Stat. 917). The words “agreement pursuant to regulations issued by the Council” are substituted for “a section 106 memorandum”, and the word “agreement” is substituted for “memorandum”, for clarity and for consistency in the new section.
