In addition to the contracts covered under 2 CFR 180.220(b) of the OMB guidance, this part applies to any contract, regardless of tier, that is awarded by a contractor, subcontractor, supplier, consultant, or its agent or representative in any transaction, if the contract is to be funded or provided by the Department of Transportation under a covered nonprocurement transaction and the amount of the contract is expected to equal or exceed $25,000. This extends the coverage of the Department of Transportation nonprocurement suspension and debarment requirements to all lower tiers of subcontracts under covered nonprocurement transactions, as permitted under the OMB guidance at 2 CFR 180.220(c) (see optional lower-tier coverage in the figure in the appendix to 2 CFR part 180).
