§ 5675. Payments
(a)
In general
Payments under this subchapter, pursuant to a grant or contract, may be made (after necessary adjustment, in the case of grants, on account of previously made overpayments or underpayments) in advance or by way of reimbursement, in such installments and on such conditions as the Administrator may determine.
(c)
Increase of grants to Indian tribes; waiver of liability
(1)
In the case of a grant under this subchapter to an Indian tribe, if the Administrator determines that the tribe does not have sufficient funds available to meet the local share of the cost of any program or activity to be funded under the grant, the Administrator may increase the Federal share of the cost thereof to the extent the Administrator deems necessary.
