S.C. Code Ann. § 17-22-100

An offender must make application to an intervention program or to the chief administrative judge of the court of general sessions no later than seventy-five days after service of the warrant or within ten days following appointment of counsel for the charge for which he makes the application. However, in the discretion of the solicitor or the chief administrative judge of the court of general sessions, if application is made directly to the judge, the provisions of this section may be waived. Applications received by the chief administrative judge of the court of general sessions under this section may be preliminarily approved by the judge pending a determination by the pretrial office that the offender is eligible to participate in a pretrial program pursuant to Sections 17-22-50 and 17-22-60. Applications received by the chief administrative judge of the court of general sessions and information obtained pursuant to Section 17-22-70 must be forwarded to the pretrial office.
