S.C. Code § 31-6-20
2012 Act No. 267, Section 1, provides as follows:
"The General Assembly finds and determines that the legislative findings contained in Section 31-6-20 of the 1976 Code remain true and correct as of the effective date of this act. The General Assembly further finds and determines that it would further the purposes of the Tax Increment Financing Law, Sections 31-6-10, et seq. of the 1976 Code, and would be in the public interest, to explicitly confirm the ability of municipalities and one or more taxing districts to provide by intergovernmental agreement for partial or modified participation in a redevelopment project. The General Assembly further finds that such intergovernmental agreements are consistent with and permissible under existing law, and accordingly the purpose of this act is to explicitly confirm the validity and enforceability of such intergovernmental agreements, whether entered into prior or subsequent to the effective date of this act. This act may not be construed to create a negative implication that any such intergovernmental agreement entered into prior to the effective date of this act is not valid or enforceable."
