S.C. Code Ann. § 50-2-50

(A) No established forestry operation is or may become a nuisance, private or public, if the forestry operation adheres to best management practices as promulgated by the South Carolina Forestry Commission. This section does not apply whenever a nuisance results from the negligent, improper, or illegal operation of a forestry operation. (B) For the purposes of this chapter, the established date of operation is the date on which the forestry operation commenced operation. If the operation is expanded subsequently or new technology adopted, the established date of operation for each change is not a separately and independently established date of operation and the commencement of the expanded operation does not divest the forestry operation of a previously established date of operation. (C) An ordinance of a county or municipality that makes a forestry operation following best management practices as promulgated by the South Carolina Forestry Commission a nuisance or providing for abatement as a nuisance in derogation of this chapter is null and void. The provisions of this section do not apply whenever a nuisance results from the negligent, illegal, or improper operation of a forestry operation.
