S.C. Code Ann. § 41-33-100: Deposit of amounts drawn by department; security.

Such lump sum amounts when received by the department from the State Treasurer must be immediately deposited by the department in a benefit payment account maintained in the name of the department in that bank or public depository and under conditions the department determines necessary. The bank or public depository must be one in which general funds of the State may be deposited, but no public deposit insurance charge or premium shall be paid out of the fund or benefit payment account. The department shall require the bank or depository it selects as the depository of the benefit payment account security in an amount equal to the amount on deposit. This security must consist of securities or a surety bond required by law of depositories of state funds.
