Achieving a Resolution
The agency and consulting parties work to reach agreement on a resolution.
In the final step of the process, the agency explores measures to avoid, minimize, or mitigate adverse effects to historic properties and reach agreement with the State (or Tribal) Historic Preservation Officer (and the ACHP in some cases) on measures to resolve them.
Were the parties able to agree on a solution?
A resolution was achieved.
A Memorandum of Agreement (MOA) or Programmatic Agreement (PA), which records the resolution measures agreed upon to resolve adverse effects, is developed in consultation and executed prior to approval of the project.
The parties were unable to reach agreement.
The federal agency must obtain formal advisory comments from the ACHP, which are sent to the head of the agency, who then must consider them in making a final decision about whether the project will proceed.
