S.C. Code Ann. § 1-11-475

It is the intent of the General Assembly that the amounts appropriated to each agency or institution in a fiscal year for employee benefits are sufficient to pay the employer contribution costs of that agency. The Department of Administration shall devise a plan for the expenditure of the funds appropriated for employer contributions and may require transfers of funds within an agency or institution if it becomes evident that the employer contribution costs exceed the funds available for that purpose.
