Alabama’s geomembrane liner market is anchored by three distinct and economically significant sectors: coal ash impoundment closure at Alabama Power’s generation fleet, channel catfish aquaculture pond liner systems in west Alabama, and paper and pulp mill wastewater lagoon containment at facilities concentrated in the Black Belt and Tennessee Valley. The state’s growing automotive manufacturing base adds secondary containment demand to this mix. International Cover Systems (ICS) brings geomembrane liner installation expertise calibrated to Alabama’s specific project types, with the CQA documentation and ADEM compliance knowledge that these applications require.
Coal Ash Impoundment Closure Under EPA CCR Rule
Alabama Power — a subsidiary of Southern Company — operates coal ash impoundments at multiple generating facilities across Alabama, including Plant Gaston in Shelby County, Plant Miller in Jefferson County, Plant Barry in Mobile County, and Plant Greene County. These impoundments are subject to EPA CCR Rule closure requirements, and Alabama Power has committed to wet impoundment closure programs that require engineered liner closure systems. Cap-in-place closures require composite cover systems with a geomembrane barrier layer meeting CCR Rule performance standards. ICS installs HDPE geomembrane liner systems for coal ash impoundment closure caps, providing the CQA documentation package — panel records, destructive coupon test results, non-destructive weld test results — required under CCR Rule quality assurance provisions and ADEM solid waste permit conditions.
Channel Catfish Aquaculture Pond Liner Systems
Alabama is the leading channel catfish producing state in the United States, with the catfish farming industry concentrated in West Alabama’s Black Belt region — particularly in Greene, Hale, Perry, and Marengo Counties, where the heavy clay soils of the Black Prairie historically supported earthen pond construction. As catfish farming has evolved to more efficient production systems — including liner-assisted ponds that improve water quality management and reduce off-flavor problems — geomembrane liner systems have become increasingly relevant for pond renovation and new construction. LLDPE and RPP liner materials are commonly used for catfish pond applications where flexibility and installation conformability to pond geometry are important. ICS brings aquaculture liner installation experience to Alabama catfish pond projects, working with producers and aquaculture engineers on liner selection and installation planning.
Paper and pulp mill wastewater lagoon liner systems — at facilities in Prattville (Georgia Pacific), Demopolis (Packaging Corporation), and the Tennessee Valley corridor — represent large-format industrial liner projects where liner integrity is critical to preventing ADEM water quality permit violations from lagoon seepage.

Frequently Asked Questions — Alabama Geomembrane Liner Installation
What liner specifications apply to Alabama Power coal ash impoundment closures under EPA CCR Rule?
Coal ash impoundment cap-in-place closures at Alabama Power facilities must meet EPA CCR Rule performance standards for cover systems. Geomembrane components are typically 60-mil HDPE, installed under the facility’s approved closure plan and CQA plan. ICS provides the full documentation package required under CCR Rule quality assurance provisions — material certifications, panel placement records, destructive coupon test results, non-destructive weld test results — and coordinates with the facility’s geotechnical engineer and CQA inspector on documentation requirements.
What liner materials are appropriate for channel catfish pond liner systems in Alabama’s Black Belt?
LLDPE and RPP are commonly specified for catfish pond liner applications due to their flexibility, which allows conformance to earthen pond geometry, and their resistance to the water quality conditions associated with catfish production. HDPE is also used for larger pond structures where stiffness is acceptable. Material selection depends on pond size, geometry, operating water depth, and producer preference. ICS works with catfish producers and aquaculture engineers on liner selection and can provide material samples for evaluation.
Does ICS install liner systems for paper and pulp mill wastewater lagoons in Alabama?
Yes. Large industrial wastewater lagoon liner installation — including aerated stabilization basins and clarifier ponds at paper mills — is within ICS’s service capability. These large-format projects require efficient panel layout and weld production to manage the installation schedule relative to mill operational constraints. ICS provides liner inspection and repair services for existing paper mill lagoon liner systems reaching the end of their service life, and can assess whether repair or full replacement is the more cost-effective approach.
What secondary containment liner applications does ICS serve in Alabama’s automotive and steel manufacturing sector?
Alabama’s Mercedes-Benz US International plant in Vance, Hyundai Motor Manufacturing Alabama in Montgomery, and Nucor Steel operations in Decatur and other locations require SPCC-compliant secondary containment for aboveground fuel and chemical storage. ICS installs HDPE and chemically resistant liner systems for secondary containment berms, process area containment pads, and bulk storage areas at manufacturing facilities. Liner material selection is coordinated with the facility’s SPCC Plan engineer based on the specific substances stored.
How does ADEM regulate liner systems for municipal landfill closures in Alabama?
ADEM’s Solid Waste Division regulates landfill liner and cap systems under Alabama regulations that align with EPA Subtitle D requirements. Landfill cap systems must include a geomembrane barrier layer as part of the final cover profile. ICS installs geomembrane components within these cap systems under CQA plans prepared by the project engineer, providing documentation consistent with ADEM solid waste permit requirements and the project’s approved CQA plan.
