Vermont’s agricultural sector operates under some of the strictest nutrient management and water quality regulations in the country, and the state’s dairy farms — concentrated in the Lake Champlain and Connecticut River watersheds — face direct compliance obligations under Act 64 and the Required Agricultural Practices (RAPs) that drive concrete liner replacement and new manure storage installation across the state. For Vermont, geomembrane liner demand is not primarily industrial or municipal — it is predominantly agricultural, shaped by the state’s commitment to protecting Lake Champlain from nutrient loading and the reality that improperly lined manure storage is one of the leading documented sources of phosphorus reaching the lake. International Cover Systems (ICS) brings agricultural liner expertise and VT DEC-aligned documentation practices to Vermont dairy farms, municipalities, and industrial project sites throughout the state.
Dairy Lagoon Liner Systems Under Vermont’s RAP Requirements
Vermont’s Required Agricultural Practices — implemented under Act 64 and enforced by VT DEC and the Agency of Agriculture — require that farms with livestock operations near water use properly engineered manure storage structures with liner systems meeting NRCS standards. For dairy farms in Addison, Franklin, Chittenden, and Orleans Counties — Vermont’s most concentrated dairy regions — this means replacing aging earthen impoundments with geomembrane-lined manure storage lagoons or upgrading existing liners that have reached the end of their service life. ICS installs HDPE and RPP liner systems for dairy lagoon applications in coordination with NRCS engineering standards and VT DEC compliance requirements. Agricultural containment liner systems are a core competency for ICS, and the material selection, subgrade preparation, and anchor detail requirements for dairy lagoon applications are well within ICS’s field experience.
Lake Champlain’s phosphorus TMDL — one of the most actively enforced nutrient reduction programs in the Northeast — makes manure storage liner compliance a high-priority issue for Vermont farms within the lake’s watershed. Farms near tributaries draining to the lake face the most direct regulatory pressure, and VT DEC enforcement of RAP compliance has increased over the past several years. ICS can work with farm owners, NRCS engineers, and agricultural consultants on liner system design, material selection, and installation scheduling.
Municipal and Specialty Agricultural Liner Applications
Beyond dairy lagoons, Vermont’s maple syrup industry — the largest in the country — requires containment systems at larger sugarhouse operations for process water and equipment wash-down. Ski resort stormwater management ponds and snowmaking reservoirs in the Green Mountains require liner systems that perform through Vermont’s demanding freeze-thaw cycles. Municipal stormwater management infrastructure under VT DEC MS4 permit requirements represents a consistent project type in Vermont’s denser communities along the major river corridors. Landfill liner and cap systems at Vermont’s municipal solid waste facilities operate under VT DEC Solid Waste Management Rules, which specify engineering requirements for liner systems at active cells and final closure installations.

Frequently Asked Questions — Vermont Geomembrane Liner Installation
What liner specifications meet Vermont’s Required Agricultural Practices (RAP) standards for dairy manure storage?
Vermont’s RAPs require that manure storage structures meet NRCS engineering standards, which typically specify a minimum liner thickness and material type based on storage volume, hydraulic head, and subgrade conditions. NRCS Conservation Practice Standard 360 (Storage Facility) provides the engineering basis for most Vermont dairy lagoon liner specifications. ICS installs HDPE and RPP liner systems that meet NRCS material and installation standards, and can provide documentation of material certifications and weld testing for NRCS engineer review.
How does the Lake Champlain phosphorus TMDL affect liner requirements for Vermont farms?
Vermont farms within the Lake Champlain watershed — which covers most of northwestern Vermont — are subject to the RAPs and potential VT DEC enforcement actions if manure storage structures are found to be leaking or inadequately lined. The phosphorus TMDL establishes load reduction targets that the state must meet, and agricultural non-point source controls — including properly lined manure storage — are a key compliance mechanism. ICS works with farm owners and NRCS engineers to design and install liner systems that satisfy VT DEC and NRCS compliance requirements.
Can ICS install liner systems for ski resort snowmaking ponds in Vermont?
Yes. Snowmaking pond liners in Vermont must perform through extended freeze-thaw cycles and withstand ice loading and pump equipment access. ICS selects liner materials — typically HDPE or LLDPE based on pond geometry and operating conditions — and installation details appropriate for Vermont’s winter climate. Anchor system design accounts for ice uplift forces and drawdown conditions. ICS coordinates liner installation with resort maintenance schedules to minimize operational disruption.
Does ICS have experience with municipal landfill liner and cap systems under VT DEC Solid Waste Management Rules?
Yes. VT DEC Solid Waste Management Rules specify engineering requirements for liner systems at active municipal solid waste landfill cells and final closure cap systems. ICS installs geomembrane components within composite liner and cap systems, coordinating with project engineers on geosynthetics installation sequencing, CQA plan execution, and documentation packages for VT DEC permit compliance.
How does ICS coordinate dairy lagoon liner projects with NRCS cost-share programs available to Vermont farms?
Many Vermont dairy farms accessing NRCS Environmental Quality Incentives Program (EQIP) cost-share funding for manure storage improvements must follow NRCS engineering standards for liner specifications and installation quality. ICS is familiar with NRCS Practice Standard requirements and can coordinate with the NRCS district engineer and farm’s agricultural consultant on liner specification, material documentation, and installation records required for EQIP payment eligibility.
