7 CFR § 2500.053 - Expiring appropriations.

(a) OAO awards supported with office appropriations. Most OAO awards are supported with annual appropriations. On September 30th of the 5th fiscal year after the period of availability for obligation ends, the funds for these appropriations accounts expire per 31 U.S.C. 1552 and the account is closed, unless otherwise specified by law. Funds that have not been drawn through the approved electronic funds transfer system, by the awardee or disbursed through any other system or method by August 31st of that fiscal year are subject to be returned to the U.S. Department of the Treasury after that date. The August 31st requirement also applies to awards with a 90-day period concluding on a date after August 31st of that fifth year. Appropriations cannot be restored after expiration of the accounts. More specific instructions are provided in the OAO award terms and conditions.

(b) OAO awards supported with funds from other Federal agencies (reimbursable funds). OAO may require that all draws and reimbursements for awards supported with reimbursable funds (from other Federal agencies) be completed prior to June 30th of the 5th fiscal year after the period of availability for obligation ends to allow for the proper billing, collection, and close-out of the associated interagency agreement before the appropriations expire. The June 30th requirement also applies to awards with a 90-day period concluding on a date after June 30th of that fifth year. Appropriations cannot be restored after expiration of the accounts. More specific instructions are provided in the terms and conditions of the OAO award agreement.
