42 U.S.C. § 300d–18 — Determination of amount of allotment

(a) Minimum allotment
Depending on how much Congress appropriates, a State's yearly allotment under section 300d–11(a) is the greater of: (1) the amount worked out under the formula in subsection (b)(1); or (2) $250,000 for each of the 50 states, the District of Columbia, and Puerto Rico, and $50,000 for each of the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands.

(b) Determination under formula
(1) The formula amount for a State^* is the sum of a population-based amount and a land-based amount.
(2) The population-based amount is 80 percent of the money appropriated under section 300d–32(a) and available for allotment, multiplied by the State's share of the total population of all States.
(3) The land-based amount is 20 percent of that same appropriated money, multiplied by the State's share of total land area — but for this calculation, a State's square mileage is capped at 266,807 square miles, whichever is smaller.

(c) Leftover appropriated funds
(1) Money that Congress set aside under section 300d–32(b)(3) but that was not paid to a State gets reallotted to the States that did receive payments for that year (except a State described in paragraph (2)(C)).
(2) This leftover money comes from States that: (A) failed to submit an application under section 300d–17; (B) failed, in the Secretary's judgment, to prepare that application in time; or (C) told the Secretary^* they will not spend their full allotment.
(3) Each eligible State's share of this leftover money equals the leftover amount multiplied by that State's population-based percentage from subsection (b)(2).
