Tennessee carries one of the most significant coal ash impoundment closure inventories in the country — shaped directly by the 2008 TVA Kingston Fossil Plant coal ash spill, the largest industrial accident of its kind in US history, which released 5.4 million cubic yards of coal fly ash into the Emory and Clinch Rivers and fundamentally reshaped federal and state coal ash regulations. TVA continues to close impoundments across Tennessee under EPA CCR Rule requirements, and the Tennessee Valley’s manufacturing sector — anchored by automotive assembly and supplier operations — generates consistent secondary containment demand. TDEC oversight of these projects requires technical documentation and installation quality standards that International Cover Systems (ICS) is equipped to provide.
Coal Ash Impoundment Closure Across Tennessee
TVA operates multiple coal ash impoundments in Tennessee at active and retired generating facilities — including Bull Run Fossil Plant in Anderson County, Cumberland Fossil Plant in Stewart County, Gallatin Fossil Plant in Sumner County, and Kingston Fossil Plant in Roane County — that are subject to EPA CCR Rule closure requirements and TDEC solid waste permit conditions. TVA’s coal ash closure program is one of the most extensive in the Southeast, with billions in remediation investment committed through the 2020s. Cap-in-place closures require composite cover systems including a geomembrane barrier layer. ICS installs HDPE geomembrane liner systems for coal ash impoundment closure caps, providing panel records, destructive coupon test results, and non-destructive weld test documentation consistent with CCR Rule quality assurance provisions and TDEC permit conditions. The Kingston site — given its regulatory significance and the scale of post-spill remediation work — has established the documentation and quality standard expectations that apply to all TVA ash closure work in the region.
Automotive Manufacturing Secondary Containment and Agricultural Pond Liners
Tennessee’s automotive manufacturing corridor — Nissan’s assembly plant in Smyrna, General Motors in Spring Hill, Volkswagen in Chattanooga, and a dense network of Tier 1 and Tier 2 supplier facilities — generates significant demand for secondary containment liner systems at chemical storage, paint shop, and process fluid management areas. SPCC-compliant secondary containment for aboveground storage tanks and process facilities at these manufacturing sites requires HDPE or chemically resistant liner systems with documented installation quality appropriate for SPCC Plan compliance. Agricultural pond liners for cattle and livestock operations in middle and west Tennessee — where row crop and livestock farming are significant — add to the state’s liner project inventory. TDEC solid waste regulations govern landfill liner and cap systems at Tennessee’s municipal solid waste facilities statewide.

Frequently Asked Questions — Tennessee Geomembrane Liner Installation
What documentation standards apply to coal ash impoundment closure liner installations at TVA facilities in Tennessee?
TVA coal ash closure projects operate under EPA CCR Rule closure plans and facility-specific CQA plans prepared by the project geotechnical engineer. Documentation requirements include material certifications for all geomembrane components, panel placement records showing seam layout and panel identification, destructive coupon test results at specified frequency, and non-destructive spark and vacuum test records for all seams. ICS provides a complete documentation package consistent with CCR Rule requirements and TVA project specification standards at each closure site.
Does ICS install secondary containment liner systems for automotive manufacturing facilities in Tennessee?
Yes. Secondary containment at automotive assembly plants and supplier facilities in Tennessee — including chemical storage berms, paint shop process area containment, and aboveground storage tank secondary containment — is within ICS’s service capability. SPCC Plan engineers specify liner materials appropriate for the chemicals stored. ICS installs these systems with SPCC-compliant dimensions and provides weld testing documentation for inclusion in the facility’s SPCC Plan records.
How did the 2008 TVA Kingston coal ash spill affect regulatory standards for coal ash liner projects in Tennessee?
The Kingston spill accelerated federal regulation of coal combustion residuals, ultimately resulting in EPA’s 2015 CCR Rule — the first federal regulation establishing engineering standards for coal ash impoundments. In Tennessee specifically, the spill established the regulatory and public scrutiny context in which all subsequent TVA ash closure work takes place. Documentation quality, installation quality assurance, and engineering rigor are at a heightened level for Tennessee coal ash projects relative to pre-Kingston standards. ICS understands this context and approaches TVA project documentation with the thoroughness these projects require.
Can ICS install liner systems for agricultural ponds in middle and west Tennessee?
Yes. Agricultural pond liners for livestock watering, irrigation reservoirs, and waste storage in middle and west Tennessee are within ICS’s agricultural liner service capability. Liner material selection depends on the application — HDPE for manure storage and waste containment, LLDPE or RPP for water supply ponds with irregular geometry. ICS coordinates installation with farm operators and NRCS engineers where EQIP cost-share funding is involved.
What is ICS’s mobilization reach into Tennessee from its Mid-Atlantic base?
ICS mobilizes to Tennessee from its Middle River, Maryland headquarters, with travel routes reaching Knoxville and Chattanooga within approximately seven to eight hours and Nashville within eight to nine hours. For major coal ash closure projects — which typically involve extended field installation schedules — ICS mobilizes crews for the project duration. Contact ICS at 667-290-4153 to discuss project-specific mobilization planning and scheduling.
