(2) for projects to reconfigure terminal baggage areas as needed to install explosive detection systems;

(3) for projects to enable the Administrator of the Transportation Security Administration to deploy explosive detection systems behind the ticket counter, in the baggage sorting area, or in line with the baggage handling system; and

(4) for other airport security capital improvement projects.

(b) Applications.— A sponsor seeking a grant under this section shall submit to the Administrator of the Transportation Security Administration an application in such form and containing such information as the Administrator of the Transportation Security Administration prescribes.

(c) Approval.— The Administrator of the Transportation Security Administration, after consultation with the Secretary of Transportation, may approve an application of a sponsor for a grant under this section only if the Administrator of the Transportation Security Administration determines that the project will improve security at an airport or improve the efficiency of the airport without lessening security.

(d) Letters of Intent.— (1) Issuance.— The Administrator of the Transportation Security Administration shall issue a letter of intent to a sponsor committing to obligate from future budget authority an amount, not more than the Federal Government’s share of the project’s cost, for an airport security improvement project (including interest costs and costs of formulating the project).

(2) Schedule.— A letter of intent under this subsection shall establish a schedule under which the Administrator of the Transportation Security Administration will reimburse the sponsor for the Government’s share of the project’s costs, as amounts become available, if the sponsor, after the Administrator of the Transportation Security Administration issues the letter, carries out the project without receiving amounts under this section.

(3) Notice to administrator of the transportation security administration.— A sponsor that has been issued a letter of intent under this subsection shall notify the Administrator of the Transportation Security Administration of the sponsor’s intent to carry out a project before the project begins.

(4) Notice to congress.— The Administrator of the Transportation Security Administration shall transmit to the Committees on Appropriations and Transportation and Infrastructure of the House of Representatives and the Committees on Appropriations and Commerce, Science 11 So in original. Probably should be “Science,”. and Transportation of the Senate a written notification at least 3 days before the issuance of a letter of intent under this section.

(5) Limitations.— A letter of intent issued under this subsection is not an obligation of the Government under section 1501 of title 31, and the letter is not deemed to be an administrative commitment for financing. An obligation or administrative commitment may be made only as amounts are provided in authorization and appropriations laws.

(6) Statutory construction.— Nothing in this subsection shall be construed to prohibit the obligation of amounts pursuant to a letter of intent under this subsection in the same fiscal year as the letter of intent is issued.

(e) Federal Share.— The Government’s share of the cost of a project under this section shall be 90 percent for a project at a medium or large hub airport and 95 percent for a project at any other airport.

(f) Sponsor Defined.— In this section, the term “sponsor” has the meaning given that term in section 47102.

(g) Applicability of Certain Requirements.— The requirements that apply to grants and letters of intent issued under chapter 471 (other than section 47102(3)) shall apply to grants and letters of intent issued under this section.

(h) Aviation Security Capital Fund.— (1) In general.— There is established within the Department of Homeland Security a fund to be known as the Aviation Security Capital Fund. The first $250,000,000 derived from fees received under section 44940(a)(1) in each of fiscal years 2004 through 2028 shall be available to be deposited in the Fund. The Administrator of the Transportation Security Administration shall impose the fee authorized by section 44940(a)(1) so as to collect at least $250,000,000 in each of such fiscal years for deposit into the Fund. Amounts in the Fund shall be available to the Administrator of the Transportation Security Administration to make grants under this section.

(2) Allocation.— Of the amount made available under paragraph (1) for a fiscal year, not less than $200,000,000 shall be allocated to fulfill letters of intent issued under subsection (d).

(3) Discretionary grants.— Of the amount made available under paragraph (1) for a fiscal year, up to $50,000,000 shall be used to make discretionary grants, including other transaction agreements for airport security improvement projects, with priority given to small hub airports and nonhub airports.

(i) Leveraged Funding.— For purposes of this section, a grant under subsection (a) to an airport sponsor to service an obligation issued by or on behalf of that sponsor to fund a project described in subsection (a) shall be considered to be a grant for that project.
