2026 West Central Landfill Unit 5A

The project involves the construction of a new waste cell at the 2026 West Central Landfill Unit 5A located at 14095 Clear Creek Road, Igo, California, 96047. Scope of work includes extensive site preparation such as clearing and grubbing, earthwork, stockpiling excavated materials, and removal of existing below-grade piping and valves. Key components include the excavation and handling of waste cover soils, installation of a comprehensive leachate collection and disposal system, and construction of landfill gas extraction wells. The cell will be lined with a multi-layer engineered system consisting of a geosynthetic clay liner, smooth and textured geomembranes, a composite drainage net, and geotextile, all subjected to conformance testing. Excavated materials will be screened and blended with bentonite and water before being placed and compacted as clay barriers. Additional work involves installing on-grade piping, permeable materials, aggregate base, culverts, and a reinforced polyethylene cover, followed by an electrical leak detection survey to ensure the integrity of the liner system. The project is governed by California Environmental Quality Act guidelines and has been classified under a Class 1 Categorical Exemption for existing facilities, with supporting documentation including a certified exemption finding, a CDFW No Effect Determination, and payment of administrative and environmental review fees. Administrative oversight is managed by Shasta County Public Works, with John Heath serving as Interim Public Works Director and Kavith Rupasinghe as Associate Engineer handling technical coordination. Payments for environmental compliance are handled via cash or check, with no electronic invoicing or federal accounting systems referenced. The project’s approval was recorded on June 16, 2026, and expired on July 20, 2026, indicating a limited window for execution tied to environmental permitting. No formal contract value, procurement type, evaluation criteria, or federal acquisition regulation clauses are documented, and no offeror representations such as UEI codes or socioeconomic certifications are required or provided, as the process is framed as an environmental exemption filing rather than a competitive federal procurement. The place of performance is strictly local, and while industry standards for geosynthetics and landfill construction are implied through technical requirements, they are not formally cited. Inspection and acceptance responsibilities rest solely with the county, occurring on-site and finalized through official county channels.
