What is the role that Tribal Historic Preservation Offices have in projects off their reservations?
THPOs take the place of SHPOs on reservation lands – meaning that agencies must consult with the Tribe and have their concurrence before proceeding with a project unless the agency instead gets that concurrence from the Advisory Council on Historic Preservation. Tribes have an important consultation role for non reservation lands they traditionally used and/or have reserved Treaty rights in. That means an agency must consult with them about projects on those patrimonial lands but Tribal concurrence is not required when deciding to proceed or not.
