Under 36 CFR § 800.14(a), federal agencies may develop their own procedures to implement Section 106, which would substitute for Subpart B of ACHP’s regulations.

Standard treatments establish practices for dealing with certain categories of undertakings, effects, historic properties, or treatment options that have been fully vetted and studied by the ACHP and Section 106 users and that carry the ACHP’s explicit endorsement. This guidance applies to standard treatments issued by the ACHP as a federal agency program alternative under § 800.14(d).
