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 EPA 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 EPA 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).
