The committee shall issue certificates of exemption to any producer who applies for such exemption and furnishes adequate evidence to the committee, that by reason of a regulation issued pursuant to §966.52 he will be prevented from handling as large a proportion of his production as the average proportion of production handled during the entire season, or such portion thereof as may be determined by the committee, by all producers in said applicant's immediate production area and that the grade, size, or quality of the applicant's tomatoes have been adversely affected by acts beyond the applicant's control and by acts beyond reasonable expectation. Each certificate shall permit the producer to handle the amount of tomatoes specified thereon. Such certificate shall be transferred with such tomatoes at time of transportation or sale.
