The terms of the newly appointed members shall begin immediately upon their appointment and qualification. Each member shall hold office after the expiration of his own term until his successor has been appointed and qualified. Within fifteen (15) days after the expiration of a term, the governor shall appoint a successor and submit that appointment to the senate for confirmation. Should any member of the board resign, die, move from the district from which he was appointed, or be removed from office, the governor shall, within thirty (30) days, appoint a successor with like qualifications to serve for the remainder of the retiring member's unexpired term. If a vacancy occurs within forty-five (45) days after the convening of the legislature and the legislature is still in session, the governor shall make a nomination to fill the vacancy and submit it to the senate for their approval.
