The Army Alternate Procedures (AAP) is a streamlined procedure Army installations can elect to follow to satisfy the requirements of Section 106 of the National Historic Preservation Act (NHPA) set forth in 36 CFR Part 800. The AAP approaches the installation's management of historic properties programmatically, instead of on a project-by-project review as prescribed by the regulations of the Advisory Council on Historic Preservation (ACHP). The AAP allows installations to implement standard operating procedures for historic properties in their Integrated Cultural Resource Management Plans (ICRMPs) and to implement actions for five years without formal project-by-project review.
