S.C. Code § 4-1-170
1993 Act No. 123, Section 7, effective June 14, 1993, provides as follows:
"SECTION 7. This act takes effect upon approval by the Governor and applies prospectively to any project for which an inducement agreement was not entered into before the effective date of this act; provided, however, that projects with respect to which an inducement agreement, millage rate agreement, or both, have been entered into before the effective date of this act are entitled but not required to use the provisions of Section 4-29-67 of the 1976 Code, as amended by this act, and also one or more of the provisions of the following subsections of Section 4-29-67 of the 1976 Code as in existence before the amendments contained in this act: (B); (F)(1)(c); (F)(2); (G); and (I); and provided further that investors having a lease agreement which was entered into before the effective date of this act meeting the eighty-five million dollar minimum level of investment required under Section 4-29-67(C) within five years from the date the lease agreement was signed shall have seven years from the date the lease agreement was signed to complete the investment, unless a longer period is otherwise stipulated in the lease agreement. The last sentence of Section 4-29-67(I) of the 1976 Code, as amended by this act, is not applicable to any project with respect to which an inducement agreement was entered into or an inducement or similar resolution was adopted by the governing body of the county before the effective date of this act; provided, however, that if an inducement agreement has not been entered into before the effective date of this act, such an agreement must be entered into with respect to any such project within one year of the effective date of this act in order for pre-inducement agreement project expenditures to qualify for the fee provided in subsection (D)(2). Any lease which was entered into with a county prior to the effective date of this act, in order to preserve the eligibility of certain property for subsequent inclusion in a fee in lieu of taxes arrangement, and which lease provides for lease payments within two dollars of what the property taxes on the leased property would otherwise have been, shall not be considered a lease agreement of any kind for purposes of beginning the running of any time period provided under Section 4-29-67 of the 1976 Code, including, but not limited to, the five, seven, and twenty-year periods provided therein. For purposes of this SECTION 7, references to inducement or millage rate agreements shall be considered to exclude any amendments or replacements of such agreements."
