Q-F03. What happens to unobligated IIJA AIG funds?

Funds not obligated at the end of the fourth fiscal year will be recovered and made available for competitive grants in the fifth year. Up to $100 million of these recovered funds will first be provided for competitive grants for FCTs. Any remaining funds will be available for competitive grants for eligible work that reduces airport emissions, reduces noise impact to the surrounding community, reduces dependence on the electrical grid, or provides general benefits to the surrounding community. Instructions for applying for these recovered funds will be outlined in a NOFO, which will be issued annually so the recovered funds are assigned to the competitive projects beginning in FY 2026 (October 1, 2025) through FY 2030 (September 30, 2030). Projects will be selected by FAA, based on sponsor’s information submitted as outlined in the NOFO. Funds recovered after the fifth year will return to the General Fund.
