Where the time of payment is contingent upon the receipt of federal funds, or federal approval, the solicitation of bids for contracts shall clearly state that payment is contingent upon those conditions. If the solicitation for bids contains the warning and a contract is awarded in response to the solicitation then interest shall not begin to accrue upon any unpaid voucher until the thirtieth day following receipt by the State or county of the contractor's statement or the thirtieth day following receipt of the federal funds or approval, whichever occurs later, and shall end as of the date of the check.
