Cal. Food and Agricultural Code § 79261

(a) Within 15 days after the effective date of this chapter, the secretary shall establish a list of producers and handlers eligible to vote on the implementation of this chapter. In establishing the list, the secretary shall require that producers and handlers of blueberries in California submit the names, mailing addresses, and the volume of blueberries produced by each producer and handled by each handler during the preceding marketing season. The request for the information shall be in writing. The information shall be filed within 10 days following receipt of the written request for information. (b) Any producer or handler of blueberries whose name does not appear upon the secretary’s list may have his or her name placed on the list by filing with the secretary a signed statement identifying himself or herself as a producer or handler. Failure to be on the list does not exempt the producer or handler from paying assessments under this chapter.
