(b) Food vendor hardship exemptions.
(1) Application for hardship exemption. A food vendor may request a hardship exemption from the requirements of this chapter by submitting a written request to the public works director. The food vendor must establish to the satisfaction of the public works director that use of environmentally-friendly food service ware will cause an undue hardship to the vendor, or that no suitable alternative to polystyrene food service ware is available in the form of environmentally-friendly food service ware. The public works director may require the food vendor to provide additional information in support of its request for a hardship exemption, including but not limited to a list of available alternative packaging materials and the reasons why those materials cannot be used without causing a hardship to the food vendor. A hardship does not exist solely on the basis that an environmentally-friendly food service ware product costs more than a similar polystyrene food service ware product.
(2) Determination. A food vendor that submits a written request for a hardship exemption will be issued a written decision by the public works director indicating whether the hardship exemption is granted. A written decision denying a hardship exemption will explain the reasons for the denial.
(3) Term. A hardship exemption is valid for a period of one year from the date the public works director approves the exemption.
(4) Successive exemptions permitted. A hardship exemption does not automatically renew, and a new application for a hardship exemption is required to obtain a successive one-year hardship exemption. There is no limit on the number of successive one-year hardship exemptions a food vendor may apply for under this section.
