 When the NPS had reorganized in the mid-1960s it had eliminated the positions of regional historians and chosen instead to merge those positions into Utley's Washington office.The 1983 reorganization of the directorates in control of Register activities represented a return to the organization pre-MISSION 66.The NHPA established the historic preservation plan for the United States not based on a U.S. governmental model but rather on that of a highly decentralized system allowing the states to carry out activities which would allow the federal government to meet the standards of the 1966 act.
