Section 3430.58 - Prior approvals(a)Subcontracts. No more than 50 percent of the award may be subcontracted to other parties without prior written approval of the ADO except contracts to other Federal agencies. Any subcontract awarded to a Federal agency under an award must have prior written approval of the ADO. To request approval, a justification for the proposed subcontractual arrangements, a performance statement, and a detailed budget for the subcontract must be submitted to the ADO.(b)No-cost extensions of time - (1)General. Awardees may initiate a one-time no-cost extension of the expiration date of the award of up to 12 months unless one or more of the following conditions apply: the terms and conditions of the award prohibit the extension; the extension requires additional Federal funds; and the extension involves any change in the approved objectives or scope of the project. For the first no-cost extension, the awardee must notify NIFA in writing with the supporting reasons and revised expiration date at least 10 days before the expiration date specified in the award.(2)Additional requests for no-cost extensions of time before expiration date. When more than one no-cost extension of time or an extension of more than 12 months is required, the extension(s) must be approved in writing by the ADO. The awardee should prepare and submit a written request (which must be received no later than 10 days prior to the expiration date of the award) to the ADO. The request must contain, at a minimum, the following information: the length of the additional time required to complete the project objectives and a justification for the extension; a summary of the progress to date; an estimate of the funds expected to remain unobligated on the scheduled expiration date; a projected timetable to complete the portion(s) of the project for which the extension is being requested; and signature of the AR and the PD.(3)Requests for no-cost extensions of time after expiration date. NIFA may consider and approve requests for no-cost extensions of time up to 120 days following the expiration of the award. These will be approved only for extenuating circumstances, as determined by NIFA. The awardee's AR must submit the requirements identified under paragraph (b)(2) of this section as well as an "extenuating circumstance" justification and a description of the actions taken by the awardee to minimize these requests in the future.(4)Other requirements. No-cost extensions of time may not be exercised merely for the purpose of using unobligated balances. All extensions are subject to any statutory term limitations as well as any expiring appropriation limitations under § 3430.63 .
