S.C. Code Ann. § 6-1-320
(B) Notwithstanding the limitation upon millage rate increases contained in subsection (A), the millage rate limitation may be suspended and the millage rate may be increased upon a two-thirds vote of the membership of the local governing body for the following purposes:
(7) to purchase capital equipment and make expenditures related to the installation, operation, and purchase of the capital equipment including, but not limited to, taxes, duty, transportation, delivery, and transit insurance, in a county having a population of less than one hundred thousand persons and having at least forty thousand acres of state forest land. For purposes of this section, "capital equipment" means an article of nonexpendable, tangible, personal property, to include communication software when purchased with a computer, having a useful life of more than one year and an acquisition cost of fifty thousand dollars or more for each unit.
If a tax is levied to pay for items (1) through (5) above, then the amount of tax for each taxpayer must be listed on the tax statement as a separate surcharge, for each aforementioned applicable item, and not be included with a general millage increase. Each separate surcharge must have an explanation of the reason for the surcharge. The surcharge must be continued only for the years necessary to pay for the deficiency, for the catastrophic event, or for compliance with the court order or decree.
