(a) The commission by rule shall set the annual distributor's license fee in an amount reasonable to defray administrative costs.
(b) In addition to the annual license fee, the commission may require an additional fee in an amount necessary to defray the cost of a background investigation of the applicant, including the inspection of storage, distribution, or operating locations. The commission by rule may establish the conditions and procedure for payment of the additional fee.
(c) The commission shall refund the fee for an initial or renewal distributor's license if the applicant requests withdrawal of the application before the license is issued or if the commission denies the application, except the commission may retain an amount not to exceed the lesser of 50 percent of the license fee or $150 to defray any administrative cost incurred by the commission in processing the application. The commission shall issue the refund not later than the 30th day after the date the commission receives the withdrawal request or denies the application.
