Cal. Food & Agric. Code § 65559

Immediately after the effective date of this chapter, the director shall establish a list of producers in each district. Such list of producers may be established from lists of such persons whose names and addresses appear on file in the Department of Agriculture. In establishing such lists of producers, the director may issue a notice to shippers, requiring them to file with the director a certified report showing the name and mail address of the shipper, and the correct names and mail addresses of producers whose producing operations are located within each district from whom the shipper received fresh grapes during the next preceding season. Notice to such shippers shall be published by the director for a period of not less than five days in a newspaper of general circulation published in each district, and shall be mailed to all shippers of record with the department. The lists of producers shall be filed by shippers within 10 days from the last date of publication of the notice.
