Summary

The TSA must give grants to airport sponsors to pay for airport security projects. Grants can cover replacing baggage conveyors, changing terminal baggage areas to add explosive detection, putting explosive detection machines behind ticket counters or into baggage systems, and other security-related capital work. Airports must apply to TSA using the form and information TSA requires. TSA, after talking with the Secretary of Transportation, will approve a project only if it makes the airport more secure or more efficient without reducing security. TSA can issue a letter of intent promising to pay up to the federal share of a project from future budget money, including interest and planning costs. The letter sets a schedule to reimburse the sponsor as money becomes available. The sponsor must tell TSA it plans to start the project before work begins. TSA must notify certain congressional committees at least 3 days before issuing a letter. The letter is not a binding government debt until money is actually authorized and appropriated, though funds can be obligated in the same fiscal year. The federal share is 90 percent for medium or large hub airports and 95 percent for other airports. Other rules that apply to similar grants and letters under chapter 471 also apply here. Sponsor: the airport sponsor defined in section 47102. There is an Aviation Security Capital Fund. The first $250,000,000 from certain fees in each fiscal year 2004 through 2028 must go into the Fund. Of that amount, at least $200,000,000 each year must be used to meet letters of intent. Up to $50,000,000 each year may be used for discretionary grants, with priority for small hub and nonhub airports. Grants used to pay off an obligation issued by a sponsor count as grants for 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.
