S.C. Code Ann. § 4-12-30
(B) In order for property to qualify for the fee, as provided in subsection (D)(2):
(2) The investment must be a project which is located in a single county or an industrial development park, as defined in Section 4-1-170. A project located on a contiguous tract of land in more than one county, but not in such an industrial development park, may qualify for the fee if:
(4)
(5)
(a) Before undertaking a project, the county council or county councils shall find:
(iii) unless the terms of an agreement with respect to a project provide that the industry shall maintain the project and carry all proper insurance with respect thereto; the estimated cost of maintaining the project in good repair and keeping it properly insured must be included in the lease payment.
The determinations and findings of the county council or county councils required to be made above must be set forth in the proceedings under which the ordinance is enacted.
(C)
(2) From the end of the property tax year in which the sponsor and the county execute the initial lease agreement, the sponsor has five years in which to complete its investment for purposes of qualifying for this section. If the sponsor does not anticipate completing the project within five years, the sponsor may apply to the county before the end of the five-year period for an extension of time to complete the project. If the county agrees to grant the extension, the county must do so in writing, and a copy must be delivered to the department within thirty days of the date the extension was granted. The extension may not exceed two years in which to complete the project. There is no extension allowed for the five-year period in which to meet the minimum level of investment. If the minimum level of investment is not met within five years, all property under the lease agreement or agreements, reverts retroactively to the payments required by Section 4-12-20. The difference between the fee actually paid by the sponsor and the payment which is due under Section 4-12-20 is subject to interest, as provided in Section 12-54-25(D). Any property placed in service after the five-year period, or seven years in the case of a project which has received an extension, is not part of the fee agreement under subsection (D)(2) and is subject to the payments required by Section 4-12-20 if the county has title to the property, or to property taxes, as provided in Chapter 37 of Title 12 if the sponsor has title to the property.
For purposes of those businesses qualifying under subsection (D)(4), the five-year period referred to in this subsection is eight years and the seven-year period is ten years.
(D) The inducement agreement must provide for fee payments, to the extent applicable, as follows:
(1)
(2) After property qualifying under subsection (B) is placed in service, an annual fee payment determined in accordance with one of the following is due:
(a) an annual payment in an amount not less than the property taxes that would be due on the project if it were taxable, but using an assessment ratio of not less than six percent, except as provided in item (4) of this subsection, and a fixed millage rate as provided in subsection (G), and a fair market value estimate determined by the department as follows:
(3) At the conclusion of the payments determined pursuant to items (1) and (2) of this subsection, an annual payment equal to the taxes due on the project as if it were taxable. When the property is no longer subject to the fee under subsection (D)(2), the fee or property taxes must be assessed:
(4)
(a) The assessment ratio may not be lower than four percent:
(F) With regard to calculation of the fee provided in subsection (D)(2), the inducement agreement may provide for the disposal of property and the replacement of property subject to the fee as follows:
(1)
(2) Any property which is placed in service as a replacement for property which is subject to the fee payment may become part of the fee payment, as provided in this item:
(G)
(H)
(I) Investment expenditures incurred by any sponsor in connection with a project, or relevant phase of a project in connection with a project completed and placed in service in more than one year, qualify as expenditures subject to the fee in subsection (D)(2), so long as those expenditures are incurred:
(J)
(1) Property which has been previously subject to property taxes in South Carolina does not qualify for the fee except as provided in this subsection:
(3) Project investment expenditures which are incurred within the applicable time period provided in subsection (I) by an entity whose investments are not being computed in the level of investment for purposes of subsection (B) or (C) qualify as investment expenditures subject to the fee in subsection (D)(2) where:
(K)
(M)
(3) All transfers undertaken with respect to other projects to effect a financing authorized under subsection (M) must meet the following requirements:
