The ACHP and eight other federal agencies developed a Memorandum of Understanding (MOU) regarding siting of transmission lines on federal lands in 2009. The MOU establishes a protocol among land managing agencies regarding the designation of a lead agency when multiple agencies are involved in a project. The MOU commits the ACHP to working cooperatively with participating agencies to ensure that these projects are fully considered under Section 106 of the NHPA without unnecessary delay.
