To continue to participate in the rotation program, each towing operator on the rotation list must file with the chief a renewal application for the following year. The renewal application must be filed during the annual enrollment period in the year prior to the year for which the renewal is sought. The application must describe any changes regarding the information in the original application. If there are no material changes and if the chief determines that the towing operator has performed well during the preceding year, the chief may place the towing operator on the rotation list for the following year. If there are material changes or if the chief determines that the towing operator has not performed well, the renewal application will be treated as if it were an original application and will be subject to the procedures for reviewing new applications, as set forth in this article and in the rules and specifications. (Ord. No. 1381, § 3 (part).)
