On-Call Environmental Compliance Consulting Services

The County of Sacramento is soliciting proposals for on-call consulting services to assist with identifying and complying with environmental regulations at the Kiefer Landfill, located at 12701 Kiefer Boulevard in southeastern Sacramento County, California. The Kiefer Landfill is a Class III facility permitted for Modules M1 through M11, with M1 opened for waste fill operations in summer 1967 and current landfilling operations occurring primarily in M4.

The landfill operates a comprehensive landfill gas (LFG) extraction system that commenced operation on January 3, 1997, consisting of vertical and horizontal extraction wells installed in Modules M1, M1-L, M2, and M3, with expansion to M4 expected in late 2025. The LFG system currently collects approximately 7,500 CFM and feeds two gas destruction flares and two gas-to-energy plants comprised of five internal combustion engines. Leachate collection systems are installed in Modules 1L, 2, 3, and 4, with leachate currently withdrawn and disposed of at a local water treatment and disposal facility.

The consulting services will support environmental sampling activities required to refine and support operations of the LFG extraction system, leachate system, and associated equipment. Environmental sampling is often required as part of environmental compliance actions and must be completed on short notice to meet regulatory demands. The on-call nature of this engagement allows the County to rapidly engage consulting resources as needed to meet time-sensitive regulatory requirements.

Key dates include Q&A Deadline of February 21, 2026, and Proposal Deadline of March 12, 2026 at 11:00 PM. This is a purchase-type RFP utilizing CMS payments for consulting services.
