(a) In General.—The head of an agency may waive a suspension of payments, termination of the contract or grant, or suspension or debarment of a contractor or grantee under this chapter with respect to a particular contract or grant if—

(1) in the case of a contract, the head of the agency determines under section 8102(b)(1) of this title, after a final determination is issued under section 8102(b)(1), that suspension of payments, termination of the contract, suspension or debarment of the contractor, or refusal to permit a person to be treated as a responsible source for a contract would severely disrupt the operation of the agency to the detriment of the Federal Government or the general public; or

(2) in the case of a grant, the head of the agency determines that suspension of payments, termination of the grant, or suspension or debarment of the grantee would not be in the public interest.

(b) Waiver Authority May Not Be Delegated.—The authority of the head of an agency under this section to waive a suspension, termination, or debarment shall not be delegated.
