S.C. Code § 58-17-1680
The Office of Regulatory Staff, in making an examination for the purpose of obtaining information pursuant to this chapter, may obtain from the commission subpoenas for the attendance of witnesses pursuant to such rules as the commission may prescribe and the witnesses must receive from the State Treasury one dollar per day and five cents per mile traveled by the nearest practical route in going to and returning from the place of meeting of the Office of Regulatory Staff, to be ordered paid by the Comptroller General upon presentation of subpoenas by the witnesses as to the number of days served and miles traveled sworn to before the clerk of the Office of Regulatory Staff. In case any person wilfully fails or refuses to obey a subpoena, any circuit judge of the court of common pleas and general sessions of any county, upon application of the Office of Regulatory Staff, must issue an attachment for the witness and compel him to attend and give his testimony upon matters lawfully required by the Office of Regulatory Staff. A circuit judge may punish for contempt as in other cases of refusal to obey the process or order of the court.
