Food & Agr. Code, § 58921

Except as otherwise provided in Section 58926, each marketing order which is issued pursuant to this chapter shall provide for the levying and collection of assessments in sufficient amounts to defray the necessary expenses which are incurred by the director in the formulation, issuance, administration, and enforcement of the marketing order. If the marketing order authorizes the carrying out of advertising and sales promotion plans, it shall also provide for the levying and collection of assessments in sufficient amounts to defray the expenses of such activities. No assessment for advertising or sales promotion activities shall, however, be levied under any marketing order with respect to the marketing and handling of green ripe olives except that green ripe olives may be assessed for their proportionate share of administrative costs.
