2026 West Central Landfill Unit 5A

The 2026 West Central Landfill Unit 5A project, managed by Shasta County Public Works, involves the construction of a new waste cell located at 14095 Clear Creek Road in Igo, California. This forecast project, categorized under NAICS code 562212, is exempt from further environmental review under the California Environmental Quality Act Section 15301 for existing facilities, with a project approval date of June 16, 2026. The scope of work is comprehensive, encompassing site preparation through clearing, grubbing, and earthwork, as well as the excavation of waste cover soils and removal of existing below-grade piping and valves. Key technical installations include leachate collection and disposal systems, the placement and compaction of clay materials, and the installation of a complex liner system featuring geosynthetic clay liners, smooth and textured geomembranes, composite drainage nets, and geotextiles. Final infrastructure requirements include the installation of on-grade piping, reinforced polyethylene covers, culverts, aggregate bases, and landfill gas extraction wells. Quality assurance will be maintained through conformance testing on geosynthetic materials and the execution of an electrical leak location survey.
