(a) From the beginning of the negotiation period until the end of the first year of implementation of an AFA, BIA may raise the issue of limitation or reduction of services, contracts, or funding. If BIA and a participating Tribe/Consortium disagree over the residual information, a participating Tribe/Consortium may ask the Deputy Commissioner—Indian Affairs to reconsider residual levels for particular programs. [See §1000.95(d)]

(b) After the AFA is signed, BIA must raise the issue of any undetermined funding amounts within 30 days after the final funding level is determined. BIA may not raise this issue after this period has elapsed.
