TSA must give grants to airport sponsors to pay for airport security building projects. Examples are replacing baggage conveyors, changing terminal baggage areas so explosive detection machines fit, putting detection equipment behind ticket counters or into baggage sorting lines, and other security capital projects. A sponsor (the airport owner or operator, see section 47102) must apply in the form TSA requires. TSA, after talking with the Secretary of Transportation, will only approve projects that make the airport more secure or make it more efficient without reducing security. For approved projects, the federal share is 90% for medium or large hub airports and 95% for all other airports. TSA can issue a letter of intent that promises to obligate future budget money up to the federal share (this can include interest and planning costs). The letter must set a schedule for reimbursing the sponsor as funds become available if the sponsor builds the project first. The sponsor must tell TSA it plans to start the project before it begins. TSA must notify certain House and Senate appropriations and transportation committees at least 3 days before issuing a letter. A letter of intent is not a legal government obligation under 31 U.S.C. 1501; the government can only obligate money when Congress provides it, though it may do so in the same fiscal year. There is an Aviation Security Capital Fund that gets the first $250,000,000 collected each year under section 44940(a)(1) for fiscal years 2004 through 2028. At least $200,000,000 of that must go to meet letters of intent each year, and up to $50,000,000 may be used for discretionary grants, with priority for small hub and nonhub airports. Grants used to pay an airport’s debt for a covered project count as grants under this program.
