(A) The fees paid pursuant to § 7.07.021 shall be deemed to be advances toward defraying the actual costs of inspection in excess of the moneys appropriated for that purpose, and shall be held pending determination of such actual additional costs.
(B) The determination of actual additional costs shall be made annually on a calendar fiscal year basis, and any money paid in and not used for purposes of this chapter shall be refunded, in proportion to the inspection fees paid in, to the owners, shippers or interested parties from whom the money was originally collected, or their assignees, or persons, firms, corporations, or associations authorized by the owners, shippers, or interested parties to receive the moneys. Refunds shall be made on or before September 30 following the close of the calendar fiscal year by warrants drawn in payment of approved and authenticated claims submitted to the County Auditor-Controller by the persons, firms, corporations or associations entitled and authorized to receive the funds. The refunds shall be reduced, on a similar proportional basis, by any excess of costs incurred over fees collected for the first six months of the current calendar year. In the event such reduction takes place, it shall be considered as an additional credit for the current calendar year.
