The Department of Revenue may suspend without prior notice a distributor's privilege to purchase stamps on the deferred-payment basis or may reduce the amount of permissible monthly purchases fixed for the distributor, if the distributor fails to pay promptly for stamps when payment is due, if the bond or bonds of the distributor are canceled, become void, impaired, or unenforceable for any reason, or if in the opinion of the department, collection of any amounts unpaid or due from the distributor under ORS 323.005 to 323.482 are jeopardized.
