Obligations secured by the special tax allocation fund set forth in § 31-7-100 for the redevelopment project area may be issued to provide for redevelopment project costs. The obligations, when so issued, must be retired in the manner provided in the ordinance authorizing the issuance of the obligations by the receipts of taxes levied as specified in § 31-7-110 against the taxable property included in the area and other revenue as specified in § 31-7-110 designated by the county which source does not involve revenues from any tax or license. In the ordinance the county may pledge all or any part of the funds in and to be deposited in the special tax allocation fund created pursuant to § 31-7-70 to the payment of the redevelopment project costs and obligations. Any pledge of funds in the special tax allocation fund must provide for distribution to the taxing districts of monies not required for payment and securing of the obligations and the excess funds are surplus funds. In the event a county only pledges a portion of the monies in the special tax allocation fund for the payment of redevelopment project costs or obligations, any funds remaining in the special tax allocation fund after complying with the requirements of the pledge are also considered surplus funds. All surplus funds must be distributed annually to the taxing districts in the redevelopment project area by being paid by the county to the county treasurer. The county treasurer shall immediately thereafter make distribution to the respective taxing districts in the same manner and proportion as the most recent distribution by the county treasurer to the affected districts of real property taxes from real property in the redevelopment project area. In addition to obligations secured by the special tax allocation fund, the county may pledge for a period not greater than the term of the obligations toward payment of the obligations any part of the revenues remaining after payment of operation and maintenance, of all or part of any redevelopment project. The obligations may be issued in one or more series, may bear such date or dates, may mature at such time or times not exceeding thirty years from their respective dates, may bear such rate or rates of interest as the governing body shall determine, may be in such denomination or denominations, may be in such form, either coupon or registered, may carry such registration and conversion privileges, may be executed in such manner, may be payable in such medium of payment, at such place or places, may be subject to such terms of redemption, with or without premium, may be declared or become due before the maturity date thereof, may provide for the replacement of mutilated, destroyed, stolen, or lost bonds, may be authenticated in such manner and upon compliance with such conditions, and may contain such other terms and covenants, as may be provided by the governing body of the county. If the governing body determines to sell any obligations the obligations must be sold at public or private sale in such manner and upon such terms as the governing body considers best for the interest of the county.

A certified copy of the ordinance authorizing the issuance of the obligations must be filed with the treasurer of each county in which any portion of a redevelopment project is situated and shall constitute the authority for the extension and collection of the taxes to be deposited in the special tax allocation fund.

A county also may issue its obligations to refund in whole or in part obligations previously issued by the county under the authority of this chapter, whether at or prior to maturity, and all references in this chapter to "obligations" are considered to include these refunding obligations. The debt incurred by a county pursuant to this chapter is exclusive of any statutory limitation upon the indebtedness a taxing district may incur. All obligations issued pursuant to this chapter shall contain a statement on the face of the obligation specifying the sources from which payment is to be made and shall state that the full faith, credit, and taxing powers are not pledged for the obligations.

The trustee or depositary under any indenture may be such persons or corporations as the governing body designates, or they may be nonresidents of South Carolina or incorporated under the laws of the United States or the laws of other states of the United States.
