(1) Use a Standard Form 30 (SF 30), Amendment of Solicitation/Modification of Contract, to settle a convenience termination by determination—

(i) When the contractor has lost its right of appeal because it failed to submit a timely settlement proposal; and

(ii) To confirm the determination when the contractor does not appeal the termination contracting officer's decision.

(2) The effective date of the SF 30 shall be the same as the date of the letter of determination. Do not assign a supplementary procurement instrument identification number to the letter of determination. Send a copy of the SF 30 to the contractor by certified mail return receipt requested.
