Phoenix Area Office - Programs & Activities

The Native American Affairs Office

FEATURE STORY: Agreement Signed for the care of Central Arizona Project Artifacts

The Reclamation Manual (RM) Directive and Standard NIA 10-01 (Requirements for Execution and Administration of Indian Self-Determination and Education Assistance Act (P.L. 93-638) Contracts and Annual Funding Agreements) has been published as a new final release, effective May 22, 2014. It is available on Reclamation's RM internet site:

The Phoenix Area Office's Native American Affairs Office (NAAO) provides a direct point of contact for tribes throughout Arizona to address tribal needs and to ensure consistency in Reclamation/tribal relationships. The primary missions of the Phoenix Native American Affairs Office are to fulfill the mandates of Reclamation law and policy as they apply specifically to Native Americans and to assist area Indian tribes in their development of water and related infrastructure on their reservations.

Tribes are sovereign nations, much like states are sovereign bodies, maintaining their own laws, regulationsregulations, and customs. Unlike states, however, the relationship between the Federal government and the tribes is a government-to-government relationship, in which the U.S. maintains a statutory trust responsibility. In 1975, Congress passed the Indian Self-Determination and Education Act (P.L. 93-638) which empowered the tribes to assume more responsibility and control of their tribal programs and functions. In essence, this means that the tribes, at their discretion, under the terms and conditions of P.L. 93-638, may request and assume responsibility for programs or projects traditionally performed by federal agencies within the Department of Interior and Department of Health and Human Services. In fact, PXAO was the first non-BIA agency to execute an annual funding agreement under the self-governance provisions of P.L. 93-638.
