25 CFR 170.213 - How long are IRRHPP funds available for a project?
Any project not under contract for construction within 3 fiscal years of its initial listing on an FPL will forfeit its unexpended funding. Applicants may request, in writing, a one-time, 1-year extension of this deadline from BIA. Upon completion of an IRRHPP, funds that are reserved but not expended are to be recovered and returned to the IRRHPP funding pool.
