S.C. Code Ann. § 11-35-1230
(1) The Office of General Services through consultation with the chief procurement officers shall develop written plans for the auditing of state procurements.
In procurement audits of governmental bodies thereafter, the auditors from the Office of General Services shall review the adequacy of the system's internal controls in order to ensure compliance with the requirement of this code and the ensuing regulations. Any noncompliance discovered through audit must be transmitted in management letters to the audited governmental body and the Budget and Control Board. The auditors shall provide in writing proposed corrective action to governmental bodies. Based upon audit recommendations of the Office of General Services, the board may revoke certification as provided for in Section 11-35-1210 and require the governmental body to make all procurements through the office of materials management above a dollar limit set by the board until such time as the board is assured of compliance with this code and its regulations by that governmental body.
