S.C. Code Ann. § 7-3-30

(a) The executive director shall notify by mail each elector at the address last filed in the office, whose name has been deleted for the reasons of conviction or a change in the residence of a qualified voter. The notice shall state the reason for the deletion and inform the elector of his right to appeal to the county board of voter registration and elections and the time in which to perfect his appeal. A copy of the notice must be forwarded to the appropriate county board of voter registration and elections. (b) Each elector whose name has been deleted has twenty days from the date the notice is mailed to appeal. The appeal must be to the county board of voter registration and elections from whose master file the deletion has been made. If the board determines that the elector's name should not have been deleted, it shall instruct the executive director to restore his name to the registration books; however, if the deletion is for conviction, the appeal must be to the Executive Director of the State Election Commission.
