NIGP 66544: Landfill Liners and Covers

NIGP 66544 Landfill Liners and Covers, an Item code, encompasses geosynthetic liner materials, protective covers, and repair services that state and local governments procure to construct and maintain environmental barriers in municipal solid waste and Class I landfill cells. Recent solicitations show demand for composite liner system components—60-mil textured HDPE geomembranes, geosynthetic clay liners, drainage geocomposites, and protective soil or geosynthetic covers—supplied as standalone materials or installed as part of full-cell construction projects, alongside on-call emergency repair services for existing liner damage. Counties and municipalities issue the work through sealed bid ITBs and RFPs for both material supply and construction installation services, with issuing bodies including county waste management departments (Sacramento County, Volusia County, San Bernardino County, Brevard County) and municipal solid waste authorities and city public works agencies (Solid Waste Authority of Palm Beach County, Town of Manchester Connecticut, City of Thomasville Georgia, City of Winter Park Florida).

Procurement activity concentrates in Florida, Georgia, and California, where landfill cell expansion and closure projects drive liner demand. Representative recent opportunities include the Town of Manchester's May 2026 ITB for up to 60,000 tons of contaminated soils as landfill cover material with a $47 per ton tip fee (bid deadline moved from May 20, 2026 due to source date anomaly), Decatur County Georgia's June 2026 RFQ for geosynthetic materials including 60-mil HDPE geomembrane, geocomposite drainage, and rain covers for MSW Cell No. 6 with a July 15, 2026 deadline, and Volusia County Florida's April 2026 ITB for Southeast Area Construction Cell I at Tomoka Farms Road Landfill encompassing composite liner installation and leachate/gas collection infrastructure with an estimated construction cost of $43.3 million. San Bernardino County issued multiple solicitations for Phase 1B Stages 4 and 5 liner construction at Victorville Sanitary Landfill covering approximately 29 acres of composite liner system placement; Sacramento County sought on-call geosynthetic liner repair services for the Kiefer Landfill on both a February 2026 RFP and June 2026 rebid RFP, with prevailing wage and apprenticeship compliance mandatory under California law. Bid security ranging from 5 to 10 percent of bid amount and performance/payment bonds at 100 percent of contract price are standard requirements. Most jurisdictions reserve award discretion to issue contracts to one or multiple vendors based on best value, with no specific set-asides for disadvantaged enterprises apparent in the solicitation materials reviewed.
