S.C. Code Ann. § 50-5-905: Permit applications; fee.

(A) A person or entity desiring to acquire a Shellfish Culture Permit or a Shellfish Mariculture Permit for any bottoms or waters must make written application to the department on a form provided by the department. A nonrefundable sum of twenty-five dollars must accompany the application for each permit. If the proposed area is available for shellfish culture or mariculture, the department shall determine:

(1) the acreage of waters or shellfish bottoms; and

(2) the acreage capable of producing shellfish.

(B) No other Shellfish Culture Permit may be granted for the bottoms delineated within an existing Shellfish Culture Permit area. However, within the perimeter boundary of an existing Shellfish Culture Permit, the department may grant permits for mariculture for waters or bottoms not then under culture permit.
