Summary
Anyone filling, dredging, draining or building in a South Carolina coastal critical area within Dorchester County, such as the tidal marsh and creek banks along the Ashley and Edisto Rivers, needs a state permit first under S.C. Code § 48-39-130(C). The law bars any change from a critical area's July 1, 1977 use without department approval, backs that with criminal and civil penalties, and allows only a short, specific list of exemptions.
(A) Ninety days after July 1, 1977, no person shall utilize a critical area for a use other than the use the critical area was devoted to on such date unless he has first obtained a permit from the department. ... (C) Ninety days after July 1, 1977 no person shall fill, remove, dredge, drain or erect any structure on or in any way alter any critical area without first obtaining a permit from the department. Provided, however, that a person who has legally commenced a use such as those evidenced by a state permit, as issued by the Budget and Control Board, or a project loan approved by the rural electrification administration or a local building permit or has received a United States Corps of Engineers or Coast Guard permit, where applicable, may continue such use without obtaining a permit. Any person may request the department to review any project or activity to determine if he is exempt under this section from the provisions of this chapter. The department shall make such determinations within forty-five days from the receipt of any such request.
Full Breakdown
Section 48-39-130(A) sets the baseline rule: 90 days after July 1, 1977, no one may put a critical area to a use different from what it was devoted to on that date without a permit from the department. Subsection (C) reaches the physical work itself, barring anyone from filling, removing, dredging, draining or erecting a structure in, or otherwise altering, a critical area without a permit, though a project already lawfully underway under a prior state or local permit may continue. A property owner unsure whether a project needs one can ask the department for a written determination, which it must issue within 45 days.
Subsection (D) exempts a specific list of activities from the permit requirement: emergency storm-protection measures such as sandbags and beach renourishment ordered by a county or municipal official, hunting and fishing where otherwise lawful, walkways over dunes built to department specifications, and normal maintenance of drainage, sewer, utility or railroad facilities, among others. 00 for a permit modification placed on public notice. The department must act within 90 days, or 30 days for minor developments, and a denial or an adversely affected neighbor may appeal to an administrative law judge under § 48-39-150(D). Violations may be restrained by the circuit court under § 48-39-160, which can also order the area restored at the violator's expense.
Violations & Fines
Under § 48-39-170(A), altering a critical area without a permit is a misdemeanor punishable by up to six months in jail or a $5,000.00 fine, or both, for a first offense, rising to a year or $10,000.00 for each later offense. A minor violation of 225 square feet or less can instead draw a $50.00 to $200.00 fine under (B), while (C) lets the department assess a civil penalty of $100.00 to $1,000.00 per day, with a three-year deadline for minor violations absent concealment.
