2014 NPDES SMS4 Stormwater General Permit

Effective January 1, 2014, Horry County must comply with the provisions of the State of South Carolina NPDES General Permit for Storm Water Discharges from Regulated Small Municipal Separate Storm Sewer Systems (SMS4) issued by South Carolina Department of Health and Environmental Control (Permit No. SCR030000). This permit replaces and updates the previous permit from 2006. While the 2014 permit continues to require local governments to address the six minimum control measures (for more information, click here), it includes new and more rigorous requirements for inspections, illicit discharge detection and monitoring, measures to address impaired waters and Total Maximum Daily Loads, and comprehensive pollutant control from new development.
