437.44—Termination for convenience.
Except as provided in § 437.43, awards may be terminated in whole or in part only as follows:
(a)
By SSA with the consent of the grantee or subgrantee in which case the two parties will agree upon the termination conditions, including the effective date and in the case of partial termination, the portion to be terminated, or
(b)
By the grantee or subgrantee upon written notification to SSA, setting forth the reasons for such termination, the effective date, and in the case of partial termination, the portion to be terminated. However, if, in the case of a partial termination, SSA determines that the remaining portion of the award will not accomplish the purposes for which the award was made, SSA may terminate the award in its entirety under either § 437.43 or paragraph (a) of this section.
