Any junkyard which comes into existence after April 6, 1967, the establishment, operation, or maintenance of which is made unlawful by Code Section 32-6-241, is declared to be a public and private nuisance and may be forthwith removed, obliterated, or abated at the order of the commissioner. The department may then submit by registered or certified mail or statutory overnight delivery a statement of the expenses of such removal, obliteration, or abatement to the person owning or operating such junkyard; and, if payment is not made to the department within 60 days of receipt thereof, the department shall certify the amount for collection to the Attorney General.
