The commission by regulation may establish advisory committees which fairly reflect the particular portion of the industry being regulated as well as other concerned groups or agencies. The members of these committees serve at the pleasure of the commission. In nominating the members of the advisory committees the director shall consult with officials of representative trade associations, the Administrator of the South Carolina Department of Consumer Affairs, the Commissioner of Agriculture, and the Commissioner of the South Carolina Department of Health and Environmental Control. The committee members serve at no cost to the State.
