(1) The Secretary shall use amounts available to the discretionary fund under section
47115 of this title for each fiscal year as follows:
(A) At least 35 percent for grants for airport noise compatibility planning under section
47505 (a)(2), for carrying out noise compatibility programs under section
47504 (c), for noise mitigation projects approved in an environmental record of decision for an airport development project under this title, for compatible land use planning and projects carried out by State and local governments under section
47141, and for airport development described in section
47102 (3)(F),
47102 (3)(K), or
47102 (3)(L) to comply with the Clean Air Act (
42 U.S.C.
7401 et seq.). The Secretary may count the amount of grants made for such planning and programs with funds apportioned under section
47114 in that fiscal year in determining whether or not such 35 percent requirement is being met in that fiscal year.
(B) at
least 4 percent to sponsors of current or former military airports designated by the Secretary under section
47118 (a) of this title for grants for developing current and former military airports to improve the capacity of the national air transportation system and to sponsors of noncommercial service airports for grants for operational and maintenance expenses at any such airport if the amount of such grants to the sponsor of the airport does not exceed $30,000 in that fiscal year, if the Secretary determines that the airport is adversely affected by the closure or realignment of a military base, and if the sponsor of the airport certifies that the airport would otherwise close if the airport does not receive the grant.
(C) In any fiscal year in which the total amount made available under section
48103 is $3,200,000,000 or more, at least two-thirds of 1 percent for grants to sponsors of reliever airports which have
(i) more than 75,000 annual operations;
(ii) a runway with a minimum usable landing distance of 5,000 feet;
(iii) a precision instrument landing procedure;
(iv) a minimum number of aircraft, to be determined by the Secretary, based at the airport; and
(v) been designated by the Secretary as a reliever airport to an airport with 20,000 hours of annual delays in commercial passenger aircraft takeoffs and landings.
(2) If the Secretary decides that an amount required to be used for grants under paragraph (1) of this subsection cannot be used for a fiscal year because there are insufficient qualified grant applications, the amount the Secretary determines cannot be used is available during the fiscal year for grants for other airports or for other purposes for which amounts are authorized for grants under section
48103 of this title.
(3) Priority.— The Secretary shall give priority in making grants under paragraph (1)(A) to applications for airport noise compatibility planning and programs at and around
(A) Chicago OHare International Airport;
(B) LaGuardia Airport;
(C) John F. Kennedy International Airport; and
