The coordinator may receive money from any source and shall deposit the funds in the Department of Pesticide Regulation Fund, or with the approval of the director, in the county treasury, for expenditure pursuant to the purposes of this article, upon appropriation therefor by the Legislature, or, if the funds are deposited in the county treasury, by the county board of supervisors. The director may, if he or she determines that it is necessary, establish fees for beekeepers and pest control operators who participate. The fees may, if necessary, vary for different regions, but shall in no case be greater than the amount necessary to defray the expenses of that region. If an unexpended surplus exists for more than two consecutive years, the surplus funds shall be transferred to the beekeeping program. If the operation of the system is suspended or terminated, any unexpended moneys shall be deposited in the Department of Food and Agriculture Fund to be used as prescribed in Section 29032.
