New York presents some of the most technically demanding geomembrane liner work in the northeastern United States. From urban Superfund sites along the East River and Gowanus Canal to upstate municipal landfill caps regulated under NYSDEC Part 360, projects here require a contractor with documented quality assurance protocols, deep regulatory familiarity, and the technical range to handle everything from large-scale remedial action plans to precision liner fabrication in tight urban footprints. ICS brings that full-service capability to New York engineers, EPC contractors, environmental consultants, and facility managers navigating NYSDEC compliance requirements.
NYSDEC Part 360 Landfill Liner and Cap Systems
New York’s solid waste management regulations under NYSDEC Part 360 establish prescriptive liner system requirements for municipal solid waste landfills, including composite bottom liners, leachate collection layers, and final cover systems. ICS installs HDPE and LLDPE liner systems that meet or exceed Part 360 specifications, and provides CQA documentation packages required for regulatory sign-off. Upstate New York municipalities operating or closing legacy landfill cells frequently require both new cell liner installation and cap system construction over existing waste mass — ICS has the equipment and field welding teams to handle concurrent liner and cap scopes on a single mobilization.
Liner welding on New York landfill projects follows ASTM D6392 (destructive) and D4437 (nondestructive) testing protocols. All hot wedge and extrusion welds are logged, tested, and documented in a project-specific CQA report delivered to the owner and submitted to NYSDEC as required.
Superfund and Brownfield Remediation Liner Systems
New York hosts a significant inventory of Superfund and state-designated brownfield sites requiring engineered containment. The Newtown Creek Superfund site in Brooklyn and the Gowanus Canal Superfund site in Brooklyn are among the most complex urban remediation projects in the region, involving sediment capping, HDPE barrier curtains, and bottom containment in active tidal environments. While each project has its own design engineer and lead remediation contractor, ICS provides specialty geomembrane installation capabilities that fit within larger remedial design-build scopes — including field fabrication, custom panel layout, and CQA-documented welding in constrained urban sites.
Hudson Valley and Capital Region brownfields associated with legacy manufacturing and chemical processing also create demand for secondary containment liner upgrades under NYSDEC’s Brownfield Cleanup Program (BCP). ICS installs HDPE and PVC liner systems for below-grade containment structures, bermed containment pads, and surface impoundments at these facilities.
CSO and Stormwater Infrastructure Containment
New York City’s Long Term Control Plan (LTCP) for combined sewer overflow (CSO) abatement has generated substantial infrastructure investment, including underground detention tanks, green infrastructure bioretention cells, and tunnel storage systems. Geomembrane liners are used in underground CSO storage tanks to provide secondary containment and prevent infiltration. ICS installs PVC and HDPE liner systems in cast-in-place concrete tanks and precast structures, with close-tolerance field fabrication and welding to accommodate the geometric complexity of underground infrastructure. Upstate New York municipalities undertaking CSO separation or storage projects under NYSDEC SPDES permit conditions similarly require liner systems as part of the treatment train.
PFAS Containment and Remediation Liner Systems
PFAS contamination at former industrial sites, fire training areas, and municipal facilities is an active and growing segment of New York environmental work. NYSDEC has established among the most stringent PFAS groundwater standards in the country, creating remediation obligations at many sites across the state. ICS installs geomembrane liner systems for PFAS containment applications, including low-permeability caps over contaminated soils, liner-lined leachate collection ponds, and secondary containment for PFAS-impacted waste streams. Liner selection for PFAS applications considers chemical resistance data for PFOA and PFOS compounds — ICS can assist design engineers with material selection based on project-specific contaminant profiles.
Agricultural and Water Storage Pond Liners
Hudson Valley agriculture, including dairy operations, orchards, and produce farms, uses lined storage ponds for irrigation water, agricultural runoff capture, and nutrient management. ICS installs agricultural pond liner systems using HDPE, LLDPE, and RPP geomembranes sized and configured to site-specific capacity and slope requirements. Agricultural liner projects in New York often require work around existing operations, and ICS coordinates installation schedules to minimize disruption to active farm operations.

Frequently Asked Questions — Geomembrane Liner Installation in New York
What NYSDEC regulations govern liner system requirements for New York landfills?
New York landfill liner and cap systems are regulated primarily under NYSDEC Part 360 (Solid Waste Management Facilities). Part 360 specifies composite liner configurations for new municipal solid waste cells, leachate collection system requirements, and final cover system design standards. Projects must be engineered by a licensed New York PE and typically require NYSDEC approval of the liner system design prior to construction. ICS provides CQA documentation packages that support the regulatory approval and closeout process.
Can ICS install geomembrane liners at active Superfund sites in New York?
Yes. ICS provides geomembrane installation services that fit within larger remediation contracts at Superfund and state brownfield sites. ICS can work as a specialty subcontractor to a lead remediation contractor or EPC firm, providing liner installation, field fabrication, and CQA-documented welding within the overall remedial action plan. Urban site constraints, confined access, and tight sequencing are factored into ICS’s project planning and mobilization approach.
What liner materials are best suited for PFAS remediation containment in New York?
HDPE is the most commonly specified liner material for PFAS containment due to its established chemical resistance profile and the availability of GRI-GM13 conformance data. For applications with high PFAS concentrations and long design lives, some engineers specify HDPE with increased thickness (60 mil or 80 mil) or specify a composite liner with a GCL underlayer. ICS can assist design engineers in evaluating material options based on the specific contaminant mix and site conditions at the project location.
Does ICS provide liner systems for New York City CSO infrastructure projects?
ICS has the technical capability to install geomembrane liner systems in underground CSO storage tanks, including PVC and HDPE liners in cast-in-place concrete and precast structures. NYC CSO projects often involve tight tolerances, complex geometry, and coordination with other trade contractors. ICS provides field fabrication services to cut and weld liner panels to the specific dimensions of each structure, and can work within the sequencing constraints of larger infrastructure projects.
How does ICS document liner quality for NYSDEC submittal?
ICS prepares a project-specific CQA (Construction Quality Assurance) report that documents material conformance, weld testing results (destructive shear and peel tests per ASTM D6392, spark testing per ASTM D4437), panel layout, and any repairs made during installation. The CQA report is structured to support regulatory submittals to NYSDEC and is provided to the project engineer of record for review and inclusion in the project closeout package.
