(NHPA).

Reclamation has determined that its operation of Glen Canyon Dam under the 2016 Record of Decision for the Glen Canyon Dam Long-Term Experimental and Management Plan is an undertaking that might result in changes to the character of downstream historic properties.

To facilitate compliance, a Programmatic Agreement (PA) was entered into by Reclamation, the Western Region and Rocky Mountain Region of the National Park Service (NPS), the Advisory Council on Historic Preservation, the Arizona State Historic Preservation Officer, the Hopi Tribe, the Hualapai Tribe, the Navajo Nation, the Zuni Pueblo, and the Paiute Consortium.

The GCDAMP, GCPA, NHPA, and PA all contain language mandating consultation with concerned Native American Tribes, for the identification, evaluation, and treatment of historic properties of significance to these Native American Tribes.

The Pueblo of Zuni participated in this process to identify, evaluate, monitor, and equally participate in the long-term management of all historic properties, sacred areas, and locations of traditional Zuni cultural use that are within the area affected by the operations of Glen Canyon Dam.

The Tribe's participation in the GCDAMP is essential to ensuring that the tribal values are represented at the various program functions and to ensure effective government-to-government consultation on federal undertakings that may affect resources important to the Tribe.
