S.C. Code Ann. § 13-1-730

The bonds authorized by the article are limited obligations of the division. The principal and interest are payable solely out of the revenues derived by the division, including any revenues that may be derived by the division pursuant to the financing agreement with respect to the project which the bonds are issued to finance. The bonds are an indebtedness payable solely from a revenue producing source or from a special source which does not include revenues from any tax or license. The bonds do not constitute nor give rise to a pecuniary liability of the division, the department, the State, or any political subdivision of the State, or to a charge against the general credit of the division, the department, the State, or any political subdivision of the State or taxing powers of the State, or any political subdivision of the State, and this fact must be plainly stated on the face of each bond. The principal of and interest on any bonds issued under this article must be secured by a pledge of the revenues from which the bonds are payable, may be secured by a security agreement, including a mortgage or any property given as security pursuant to a financing agreement, and may be additionally secured by a pledge of the financing agreement with respect to the project. In making any agreements or provisions, the division does not have the power to obligate itself or the department with respect to any project for which the proceeds of bonds issued under this article have been loaned to a company, except with respect to the project and the application of the revenues from the financing agreement, and does not have the power to incur a pecuniary liability or a charge upon its general credit or upon the general credit of the department. The trustee under any security agreement or indenture, or any depository specified by the security agreement or indenture, may be any person or corporation as the division designates, notwithstanding that the trustee may be a nonresident of this State or incorporated under the laws of the United States or the laws of other states.
