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.
