S.C. Code § 48-30-40
There is levied in assessment on all primary forest products harvested from lands within the State at rates established in Section 48-30-60 and the proceeds of such assessment shall be deposited in the forest renewal fund as provided in Section 48-28-100.
Collection of the assessment shall be suspended in any fiscal year in which the General Assembly fails to make general fund appropriations to the forest renewal fund.
Collection of the assessment shall be suspended in any fiscal year in which there is carried forward from previous years a balance of unobligated funds in the forest renewal fund greater than four times the amount appropriated from the general fund for that fiscal year.
If the assessment is suspended because of either paragraph 2 or 3 of this section, the suspension shall cease when the condition causing the suspension no longer exists.
