S.C. Code Ann. § 11-11-325

At any time during the current fiscal year, if the Board of Economic Advisors' revenue forecast projects that revenues for the current fiscal year will be less than appropriated expenditures for this year, the Director of the Executive Budget Office in mandating necessary cuts during the current fiscal year to eliminate the projected deficit must first reduce to the extent necessary the appropriation to the Capital Reserve Fund, prior to mandating any cuts in operating appropriation.
