A marketing program may authorize the marketing program committee to create, by a uniform assessment upon producers based upon the volume of the commodity which is marketed by each, or upon some other uniform and equitable basis, maintain, and disburse an equalization fund to be used for the removal of any inequalities between producers as to the total volume which is marketed through prorated channels that result from errors in estimating production or surplus, or for indemnifying producers whose production, in whole or in part, is diverted in green form or otherwise from normal marketing outlets, or diverted to relief, byproducts, or other noncompetitive purposes pursuant to a marketing program.
