36 CFR § 800.14(b)(4)

The ACHP can designate an agreement document as a prototype that can be used for the same type of program or undertaking in more than one program or area. When a federal agency uses a prototype programmatic agreement, the agency may develop and execute the agreement with the appropriate SHPO/THPO without the need for the ACHP's participation in consultation or ACHP signature. 

The benefits of a prototype agreement include expediting review of routine activities with limited potential to affect historic properties; providing predictability in the treatment of historic properties through the use of a template agreement; and allowing the federal agency and SHPO/THPO to execute such agreements without ACHP involvement. Once a prototype agreement is designated by the ACHP, agencies can use it exactly as approved for subsequent agreements with individual SHPOs/THPOs or modify the language to meet their particular needs so long as they stay within the broad parameters established by the ACHP for the prototype agreement.
