(3) Exclusion of such product or service from the project would increase the cost of the overall project contract by more than 20 percent.
(b) The President or the Secretary may waive the restrictions imposed by section 109(a) of the Continuing Resolution with respect to an individual contract if the President or the Secretary determines that such action is necessary in the public interest, on a contract-by-contract basis. The Secretary may apply the factors listed in paragraphs (a)(2) and (a)(3) of this section in determining whether a waiver is in the public interest.
(c) The authority of the President or the Secretary to issue waivers may not be delegated.
