S.C. Code § 11-51-160
General obligation debt must be sold by the Governor and the State Treasurer upon sealed proposals, after publication of a summary notice of the sale one or more times at least seven days before the sale, in a financial paper published in New York City which regularly publishes notices of sale of state or municipal bonds. The general obligation debt may be awarded upon the terms and in the manner as prescribed by the State Treasurer. The right is reserved to reject bids and to re-advertise the general obligation debt for sale. For the purpose of bringing about successful sales of the general obligation debt, the State Treasurer may do all things ordinarily and customarily done in connection with the sale of state or municipal bonds. Expenses incident to the sale of the general obligation debt must be paid from the proceeds of the sale of the general obligation debt.
