(1) The lessee or licensee shall deliver all grain crops to an elevator on or before November 15 in the year of harvest, free of charges, taxes, or assessments to the credit of the state. If elevators cannot accommodate state grain at harvest time, the lessee or licensee shall provide storage free of charge until marketing. Other agricultural crops shall be disposed of at the going market price unless otherwise directed. The department shall permit lessees or licensees to purchase the state's share of all crops; however, department approval is required before a lessee or licensee may purchase state crops. Applications shall be made on the prescribed forms in current use, furnished at no cost by the department. The lessee or licensee shall be required to submit all applicable crop reports, a crop analysis and a certification of market price for the crop from a licensed dealer on forms provided by department. The lessee or licensee shall make full payment within 10 days from the date of certification but no later than November 15. The lessee or licensee may also contract for purchase of state crops; however, all contracts must be approved by the department in advance and filed with the department. Extensions for rental payment may be granted in this instance pursuant to ARM 36.25.112.
