Cal. Food & Agr. Code § 72091
Within 90 days after January 1, 1983, the director shall establish a list of producers eligible to vote on implementation of this chapter. In establishing the list, the director shall require that handlers, county agricultural commissioners, and wheat producers in this state submit the names, mailing addresses, and district numbers of all wheat producers. The request for this information shall be in writing. The list shall be filed within 30 days following receipt of the written notice.
Any producer of wheat, whose name does not appear upon the director's list of producers affected, may have his name established on the list by filing with the director a signed statement, identifying himself as a producer. Failure to be on the list does not exempt the producer from paying assessments under this chapter.
