South Carolina’s geomembrane liner market is driven by coal ash impoundment closure activity that ranks among the most active in the Southeast, a significant agricultural sector in the Pee Dee region, and coastal stormwater complexity along the Grand Strand and Lowcountry. Duke Energy and Santee Cooper operate multiple coal ash impoundments in South Carolina that are subject to EPA CCR Rule closure deadlines — placing SC among the states with the highest near-term demand for engineered liner closure systems. International Cover Systems (ICS) brings the coal ash liner installation expertise, CQA documentation practices, and SCDHEC compliance knowledge that South Carolina project sites require.
Coal Ash Impoundment Closure and Industrial Liner Systems
Duke Energy’s South Carolina fleet — including Wateree Station, Robinson Nuclear Plant ash basins, and other legacy impoundments — along with Santee Cooper’s ash basins at Cross and Winyah Generating Stations, face EPA CCR Rule compliance deadlines for wet impoundment closure. Cap-in-place closure options require composite cover systems with geomembrane barrier layers meeting CCR Rule performance standards. ICS installs HDPE geomembrane liner systems for coal ash impoundment closure cap systems, providing the CQA documentation — panel placement records, destructive coupon test results, non-destructive weld test results — required under CCR Rule quality assurance provisions and SCDHEC solid waste permit conditions.
Upstate South Carolina’s automotive manufacturing corridor — BMW’s Spartanburg plant, Michelin’s North American operations, and a network of Tier 1 and Tier 2 supplier facilities — generates secondary containment demand for chemical storage, process fluids, and industrial wastewater systems. SPCC-compliant secondary containment liner systems for aboveground storage tanks and process areas at these manufacturing facilities are within ICS’s service capability.
Agricultural Lagoon Systems and Coastal Stormwater Management
The Pee Dee region in northeastern South Carolina — Florence, Horry, Marlboro, Chesterfield, and Darlington Counties — supports significant poultry and swine production that drives agricultural lagoon liner demand. SCDHEC’s animal feeding operation program requires properly designed and maintained manure storage structures for regulated operations, and liner systems that prevent leachate from reaching the shallow surficial aquifer underlying the Coastal Plain are a key compliance element. Agricultural containment liner systems for swine and poultry waste storage are a consistent project type for ICS in the Pee Dee market.
The Grand Strand and Lowcountry coastal regions generate stormwater management liner demand driven by development pressure and SCDHEC MS4 stormwater permit compliance. Stormwater retention ponds and wet detention basins in high-density coastal development areas — particularly in Horry, Georgetown, Beaufort, and Jasper Counties — incorporate liner systems to achieve hydraulic control and prevent seepage into coastal groundwater.

Frequently Asked Questions — South Carolina Geomembrane Liner Installation
What liner system specifications apply to coal ash impoundment cap closures under EPA CCR Rule in South Carolina?
EPA’s CCR Rule specifies performance standards for coal ash impoundment closure cover systems. Cap-in-place closures must achieve hydraulic conductivity performance equivalent to a composite cover barrier. Geomembrane layers in CCR closure caps are typically 60-mil HDPE, installed under an approved closure plan and CQA plan prepared by the facility’s geotechnical engineer. ICS provides panel placement records, destructive coupon test results, and non-destructive weld test documentation consistent with CCR Rule quality assurance requirements and SCDHEC solid waste permit conditions.
Does ICS install secondary containment liner systems for automotive manufacturing facilities in Upstate South Carolina?
Yes. Secondary containment for aboveground storage tanks and process areas at automotive manufacturing facilities in the Upstate SC corridor is within ICS’s service capability. Liner material selection — HDPE, LLDPE, or chemically resistant XR-5 depending on stored materials — is coordinated with the facility’s SPCC Plan engineer. ICS provides SPCC-compliant installation with weld testing documentation.
How does SCDHEC regulate agricultural lagoon liner systems for swine and poultry operations in the Pee Dee region?
SCDHEC’s animal feeding operation program under the Swine Farm Act and general NPDES agricultural wastewater permits specifies design and liner requirements for waste storage structures at regulated operations. Liner systems must prevent seepage to groundwater at rates exceeding permit thresholds. ICS installs HDPE and RPP liner systems for agricultural waste lagoons in coordination with the farm’s professional engineer and SCDHEC permit conditions. Material and installation documentation is provided for SCDHEC compliance files.
What stormwater liner applications does ICS serve along South Carolina’s coastal corridor?
Coastal development in Horry, Georgetown, Beaufort, and Jasper Counties requires stormwater management infrastructure — retention ponds, wet detention basins, and infiltration control structures — that often incorporates geomembrane liner systems. SCDHEC MS4 permit compliance and local land development standards specify stormwater BMP design requirements. ICS installs liner systems for these coastal stormwater applications and provides documentation for SCDHEC permit compliance.
Can ICS provide liner systems for brownfield remediation at former textile mill sites in Upstate South Carolina?
Yes. Textile mill brownfield sites in the Upstate Piedmont — particularly in Spartanburg, Cherokee, and Union Counties — may have soil and groundwater contamination from dye, solvent, and process chemical use. Remediation containment systems for these sites operate under SCDHEC Brownfields/Voluntary Cleanup Program requirements. ICS installs containment liner systems appropriate for the contaminant profiles at textile brownfield sites, with CQA documentation for SCDHEC program submissions.
