S.C. Code Ann. § 60-2-30

All state agencies, departments, and state-supported colleges and universities must provide at least fifteen copies of every state publication that the agency, department, college, or university prints or causes to be printed to the State Library within fifteen days after the printing. A publication produced only in electronic format must be electronically provided to the State Library within fifteen days of the publication's posting or distribution. The State Library Director may waive the deposition of any agency publication if: (1) the publication is of ephemeral value; (2) less than ten copies are to be printed and no electronic version is available; or (3) the issuing agency requests a waiver.
