Wetlands Outside the Coastal Zone Outside the 8 coastal counties there is no existing regulatory framework to manage the filling of nonjurisdictional (non-federally regulated) wetlands. DHEC regulates the discharge of fill to jurisdictional wetlands in accordance with Section 401 of the Clean Water Act. Section 401 of the CWA provides states with authority to certify federal permits or licenses for activities that result in discharges to waters of the state including wetlands. South Carolina’s 401 Certification program only gives DHEC the authority to regulate jurisdicational wetlands.
