Q-U24. Can IIJA funds be used to reimburse costs previously incurred?

For all AIG Allocated funds and funds awarded under the FY 2022 ATP NOFO and the FY 2022 FAA Contract Tower (FCT) Competitive Grant Program NOFO, FAA will reimburse sponsors for eligible project related costs incurred on or after November 15, 2021, which is the date of enactment of IIJA, as long as all Federal funding procurement requirements and FAA design and construction standards, are met (see the AIP Handbook).

After further legal review, the FY 2023 and future ATP, FCT Competitive, and other IIJA related NOFOs will be adjusted to further ensure consistency with other DOT grant programs. Project formulation costs (airport development), incurred after November 15, 2021, are reimbursable. The specific costs eligible for reimbursement are outlined under 49 U.S.C. 47110(c), and further described in Table 3-60 of the AIP Handbook. All other costs must be incurred after grant execution.
