In refund situations it may be necessary to request the assistance of the State Department
            in recovering an overpayment.
         
         If adjustment of the overpayment becomes available (or recovery is waived) after the
            State Department's assistance has been requested, notify them promptly to discontinue
            their recovery efforts.
         
         Once the State Department has been told to discontinue recovery efforts, do not make
            a second request for assistance if adjustment ceases to be available and full recovery
            was not possible. Terminate collection efforts (ROAR TC 71).
