S.C. Code § 46-10-120
The Boll Weevil Eradication Program, as provided for under this chapter, must be implemented for a specified time determined by the commission if it determines that the federal government and the commercial cotton producers of this State, as determined by referendum conducted by the commission, shall cooperate and provide for the cost of carrying out the provisions of this chapter for the specified time. The cotton producer referendum must receive the favorable vote of two-thirds of the producers casting votes. All commercial cotton producers in South Carolina shall receive ballots and are eligible to vote.
Upon termination of the time specified in the last referendum, the commission shall establish an assessment, not to exceed ten dollars an acre, to cover suppression and containment costs on all cotton acreage within the eradication area as long as a containment program is necessary. This assessment and program duration is subject to change when petitioned by ten percent of the commercial cotton producers of this State.
