(a) Each first purchaser of milk which purchases milk from at least twenty-one milk producers may submit to the Governor the names of up to two nominees for each forty milk production units, or major portion thereof, from which the first purchaser purchases milk. The Governor shall appoint one member for each forty production units, or major portion thereof, from nominees submitted pursuant to this subdivision, except that if milk production units certified by the Department of Agriculture have decreased so that each board member appointed pursuant to this subdivision represents less than a major portion of forty production units, the Governor shall maintain representation of one member for each forty production units, or major portion thereof, by not filling a vacancy caused by a member's term expiring; and
(b) All other first purchasers of milk and individual producer-processors who are not included among milk production units claimed by a first purchaser of milk entitled to submit nominees under subdivision (1)(a) of this section shall be combined as a group for the purpose of submitting nominees, and each first purchaser and individual producer-processor of the group may nominate up to two nominees. The Governor shall appoint two members from nominees submitted pursuant to this subdivision.
(2) Whenever the number of members of the board as determined by subsection (1) of this section results in less than seven members, the Governor shall appoint a member or members from the state at large to maintain membership of the board at seven members. Whenever such appointment is required, the board shall call for and submit a list of two or more nominees for each additional member needed to the Governor, and the Governor shall appoint a member or members from the nominees submitted pursuant to this subsection.
(3) Nominations in the case of term expiration or new or at-large membership and for all other vacancies shall be provided according to the process prescribed in section 2-3951.04. The Governor may choose the members of the board from the nominees submitted or may reject all nominees.
