S.C. Code § 4-1-175
A county or municipality receiving revenues from a payment in lieu of taxes pursuant to Section 13 of Article VIII of the Constitution of this State may issue special source revenue bonds secured by and payable from all or a part of that portion of the revenues which the county is entitled to retain pursuant to the agreement required by Section 4-1-170 in the manner and for the purposes set forth in Section 4-29-68. The county or municipality may pledge the revenues for the additional securing of other indebtedness in the manner and for the purposes set forth in Section 4-29-68.
A county or municipality or special purpose district that receives and retains revenues from a payment in lieu of taxes pursuant to Section 13 of Article VIII of the Constitution of this State may use a portion of this revenue for the purposes outlined in Section 4-29-68 without the requirement of issuing the special source revenue bonds or meeting the requirements of Section 4-29-68(A)(4) by providing a credit against or payment derived from the revenues received and retained under Section 13 of Article VIII of the Constitution of this State.
A political subdivision of this State subject to the limitation of either Section 14(7)(a) or Section 15(6) of Article X of the Constitution of this State pledging pursuant to this section all or a portion of the revenues received and retained by that subdivision from a payment in lieu of taxes to the repayment of any bonds shall not include in the assessed value of taxable property located in the political subdivision for the purposes of calculating the limit imposed by those sections of the Constitution any amount representing the value of the property that is the basis of the pledged portion of revenues. If the political subdivision, before pledging revenues pursuant to this section, has included an amount representing the value of a parcel or item of property that is the subject of a payment in lieu of taxes in the assessed value of taxable property located in the political subdivision and has issued general obligation debt within the debt limit calculated on the basis of such assessed value, then it may not pledge pursuant to this section revenues based on the item or parcel of property, to the extent that the amount representing its value is necessary to permit the outstanding general obligation debt within the debt limit of the political subdivision.
