The Secretary shall negotiate and enter into a written funding agreement with each Indian tribe participating in self-governance in a manner consistent with the Federal Government’s trust responsibility, treaty obligations, and the government-to-government relationship between Indian tribes and the United States.
Each funding agreement required under subsection (a) of this section shall, as determined by the Indian tribe, authorize the Indian tribe to plan, conduct, consolidate, administer, and receive full tribal share funding, including tribal shares of discretionary Indian Health Service competitive grants (excluding congressionally earmarked competitive grants), for all programs, services, functions, and activities (or portions thereof), that are carried out for the benefit of Indians because of their status as Indians without regard to the agency or office of the Indian Health Service within which the program, service, function, or activity (or portion thereof) is performed.
It shall not be a requirement that an Indian tribe or Indians be identified in the authorizing statute for a program or element of a program to be eligible for inclusion in a compact or funding agreement under this subchapter.
Absent notification from an Indian tribe that is withdrawing or retroceding the operation of one or more programs, services, functions, or activities (or portions thereof) identified in a funding agreement, or unless otherwise agreed to by the parties, each funding agreement shall remain in full force and effect until a subsequent funding agreement is executed, and the terms of the subsequent funding agreement shall be retroactive to the end of the term of the preceding funding agreement.
At the option of an Indian tribe, a funding agreement may provide for a stable base budget specifying the recurring funds (including, for purposes of this provision, funds available under section 5325(a) of this title) to be transferred to such Indian tribe, for such period as may be specified in the funding agreement, subject to annual adjustment only to reflect changes in congressional appropriations by sub-sub activity excluding earmarks.
