Within 90 days after final approval of any proposed wheat development program by the temporary wheat development program committee, the Director shall determine by referendum whether the affected producers assent to the proposed wheat development program. The proposed wheat development program is approved when a majority of those voting in the referendum vote in favor of the proposed wheat development program. Following approval of the program, the Department shall file the program with the Secretary of State as provided in Section 5-65 of the Illinois Administrative Procedure Act.
     If a proposed wheat development program is not approved by referendum, no additional referendum on a wheat development program may be held for 2 years from the date of the close of the referendum period. An additional referendum shall be called by the Director upon request by petition of 500 producers of wheat from across the State. Before holding an additional referendum, the Director shall appoint a temporary wheat development program committee consisting of 7 members who are wheat producers nominated by an association representing wheat producers. The temporary wheat development program committee shall follow the procedures set forth in Section 25.
