In 1996 the national historic preservation program entered a new era, as fourteen Indian tribes were approved by NPS to assume national program responsibilities on tribal lands, pursuant to Section 101(d)
of the National Historic Preservation Act. Among the responsibilities assumed by these tribes are conducting historic property surveys, maintaining permanent inventories of historic properties, nominating properties to the National Register of Historic Places, and reviewing Federal agency undertakings pursuant to Section 106 of the Act.
