Section 106 comes from the National Historic Preservation Act of 1966, also known as 36 CFR (Code of Federal Regulations) Part 800. Section 106 is enacted for projects, known as undertakings, that handle federal property or are funded, approved, permitted, or licensed by a federal agency. Section 106 is a four-step process, detailed below. An undertaking that may adversely affect historic properties can only proceed once a Memorandum of Agreement (MOA) or a Programmatic Agreement (PA)is reached.
