If a bidder or offeror who otherwise would have been awarded a contract is found not to be a responsible bidder or offeror, a determination that the bidder or offeror is not a responsible bidder or offeror, setting forth the basis of the finding, shall be prepared by the state purchasing agent or a central purchasing office. The unreasonable failure of a bidder or offeror to promptly supply information in connection with an inquiry with respect to responsibility is grounds for a determination that the bidder or offeror is not a responsible bidder or offeror.
