The County of Sacramento operates the Kiefer Landfill Facility (KLF) for the disposal of Class III municipal solid waste, serving residents and businesses within Sacramento County and nearby cities. The landfill has undergone several expansions of its base liner system—a crucial subsurface barrier designed to prevent the release of waste and contaminants into the surrounding environment. The landfill's base liner system spans multiple modules, from M1L through M11, with Module M1 being the original unlined area dating back to 1967, and active landfilling currently taking place in Module M4. Future landfill modules (M5 through M11) will be constructed to accommodate growing disposal demands, with varying liner materials and system components due to phased construction over time. The current solicitation, titled "Rebid of On-Call Landfill Liner System Repair Services," is issued by the Waste Management and Recycling agency of California and pertains to ongoing maintenance and repair of the landfill's base liner system. This contract aims to engage qualified service providers capable of addressing the diverse materials and components of the liner system to ensure continued environmental protection and landfill operation. The solicitation was posted on April 20, 2026, with proposals due by May 29, 2026. The designated point of contact for this solicitation is Melissa Burnias, Senior Contract Services Officer, based in Sacramento, California.

Full Description

Show more
The County owns and operates the KLF for the disposal of Class III municipal solid waste, servicing the residences and businesses within the County of Sacramento and nearby cities. Periodically, the KLF extends the landfill base liner system to incorporate more airspace to deposit waste. The landfill liner system is a subsurface barrier that contains waste and waste constituents from being released into the surrounding environment. The Kiefer Landfill is permitted for base liner systems in Modules M1L through M11. Module M1 (the original unlined area) was opened for waste fill operations in the summer of 1967. Module M-1L was opened for waste fill operations in March 1994 with the initial base liner system. Currently, landfilling is occurring in Module M4. Modules 5 through 11 will be constructed in the future to meet the local demand for disposal service. Since the landfill liner has been constructed in multiple phases, the liner system components and material types vary. A summary of the various liner system components is included with this request for proposals as Attachment A - Table 1 Base Liner System Components.
