To allow for possible late payments due to unexpected problems arising at financial institutions, federal reserve facilities, the automated clearing house system, or state agencies where it is proven that a good faith attempt was made and due diligence was exercised to initiate payment correctly and on a timely basis, the administering state agency is specifically authorized to waive all penalties, interest, or disallowed discount on late payments for a period not to exceed two business days following the due date of the payment.
