# §4631. Federal share of costs

- (a) **Cost to displacing agency; eligibility—** The cost to a [displacing agency](/usc/42/4601.md?p=11) of providing payments and assistance under this subchapter and subchapter III of this chapter shall be included as part of the cost of a program or [project](/usc/42/13641.md?p=2) undertaken by a [Federal agency](/usc/42/4601.md?p=1) or with [Federal financial assistance](/usc/42/4601.md?p=4). A [displacing agency](/usc/42/4601.md?p=11), other than a [Federal agency](/usc/42/4601.md?p=1), shall be eligible for [Federal financial assistance](/usc/42/4601.md?p=4) with respect to such payments and assistance in the same manner and to the same extent as other program or [project](/usc/42/13641.md?p=2) costs.
- (b) **Comparable payments under other laws—** No payment or assistance under this subchapter or subchapter III of this chapter shall be required to be made to any [person](/usc/42/4601.md?p=5) or included as a program or [project](/usc/42/13641.md?p=2) cost under this section, if such [person](/usc/42/4601.md?p=5) receives a payment required by Federal, [State](/usc/42/4601.md?p=2), or local law which is determined by the head of the [Federal agency](/usc/42/4601.md?p=1) to have substantially the same purpose and effect as such payment under this section.
- (c) **Agreements prior to January 2, 1971; advancements—** Any grant to, or contract or agreement with, a [State agency](/usc/42/4601.md?p=3) executed before January 2, 1971, under which [Federal financial assistance](/usc/42/4601.md?p=4) is available to pay all or part of the cost of any program or [project](/usc/42/13641.md?p=2) which will result in the displacement of any [person](/usc/42/4601.md?p=5) on or after January 2, 1971, shall be amended to include the cost of providing payments and services under sections [4630](/usc/42/4630.md) and [4655](/usc/42/4655.md) of this title. If the head of a [Federal agency](/usc/42/4601.md?p=1) determines that it is necessary for the expeditious completion of a program or [project](/usc/42/13641.md?p=2) he may advance to the [State agency](/usc/42/4601.md?p=3) the Federal share of the cost of any payments or assistance by such [State agency](/usc/42/4601.md?p=3) pursuant to sections [4626](/usc/42/4626.md), [4630](/usc/42/4630.md), [4635](/usc/42/4635.md), and [4655](/usc/42/4655.md) of this title.
