S.C. Code § 4-29-40
The principal of and interest on any bonds issued under the authority of this chapter shall be secured by a pledge of the revenues from which such bonds shall be payable, may be secured by a security agreement covering all or any part of the project from which the revenues so pledged are derived, or any property given as security by the industry pursuant to the financing agreement, and may be additionally secured by a pledge of the financing agreement with respect to such project. The proceedings under which such bonds are authorized to be issued or any such security agreement may contain any agreements and provisions customarily contained in instruments securing bonds, including, without limiting the generality of the foregoing, provisions respecting the fixing and collection of obligations owning under any financing agreement for any project covered by such proceedings or security agreement, the terms to be incorporated in the financing agreements, the maintenance and insurance of the project, the creation and maintenance of special funds, and the rights and remedies available in the event of default to the bondholders or to the trustee under such security agreement, all as the governing board shall deem advisable and as shall not be in conflict with the provisions of this chapter; provided, however, that in making any such agreements or provisions a county or incorporated municipality shall not have the power to obligate itself except with respect to the project and the application of the revenues from the financing agreement, and shall not have the power to incur a pecuniary liability or a charge upon its general credit or against its taxing powers. The proceedings authorizing any bonds hereunder and any security agreement securing such bonds may provide that, in the event of default in payment of the principal of or the interest on such bonds or in the performance of any agreement contained in such proceedings or security agreement, such payment and performance may be enforced by mandamus or by the appointment of a receiver in equity with power to charge and collect obligations owing under any financing agreement and to apply the revenues from the project in accordance with such proceedings or the provisions of such security agreement. Any such security agreement may provide also that in the event of default in payment or the violation of any agreement contained in the security agreement, it may be foreclosed by proceedings at law or in equity, and may provide that any trustee under the security agreement or the holder of any of the bonds secured thereby may become the purchaser at any foreclosure sale, if he is the highest bidder. No breach of any such agreement shall impose any pecuniary liability upon a county or incorporated municipality or any charge upon its general credit or against its taxing power.
The trustee or trustees under any security agreement, or any depository specified by such security agreement, may be such persons or corporations as the governing board shall designate, notwithstanding that they may be nonresident of South Carolina or incorporated under the laws of the United States or the laws of other states of the United States.
