40 U.S.C. § 18304: Procedures for enforcement of awards

Within 10 days after the parties receive an arbitration award to which section 18303 of this title applies, the interstate compact agency and the employees, through their representative, may agree in writing on any modifications to the award. After the end of that 10-day period, the award, and any modifications, become binding on the interstate compact agency, the employees in the bargaining unit, and the employees’ representative.
