(a) The funds to cover the committee's expenses shall be acquired by the levying of assessments upon handlers as provided in this subpart. Each person who first handles Walla Walla Sweet Onions shall pay assessments to the committee upon demand, which assessments shall be in payment of such handler's pro rata share of the committee's expenses.

(b) Assessments shall be levied upon handlers, at rates established by the Secretary. Such rates may be established upon the basis of the committee's recommendations or other available information.

(c) At any time during, or subsequent to, a given fiscal period, the committee may recommend the approval of an amended budget and an increase in the rate of assessment. Upon the basis of such recommendations, or other available information, the Secretary may approve an amended budget and increase the assessment rate. Such increase in the assessment rate shall be applicable to all Walla Walla Sweet Onions which were handled by each handler thereof during such fiscal period.

(d) The payment of assessments for the maintenance and functioning of the committee may be required under this part throughout the period it is in effect, irrespective of whether particular provisions of this part are suspended or become inoperative.

(e) To provide funds for the administration of the provisions of this part during the initial fiscal period or the first part of a fiscal period when neither sufficient operating reserve funds nor sufficient revenue from assessments on the current season's shipments are available, the committee may accept payment of assessments in advance or may borrow money for such purposes.

(f) The committee may impose a late payment charge or an interest charge, or both, on any handler who fails to pay any assessment in a timely manner. Such time and the rates shall be recommended by the committee and approved by the Secretary.
