On-call maintenance, repair, and modification of LFG systems at kiefer landfill and ELK grove landfill

Sacramento County's Department of Waste Management and Recycling (DWMR) is issuing Request for Proposals (RFP) #2025-PURB RFP-0040 for specialized on-call maintenance, repair, and modification services for landfill gas (LFG) collection and control systems at Kiefer and Elk Grove Landfills. The procurement seeks a contractor to provide emergency services involving maintenance and repair of LFG wellheads, HDPE lateral and header piping, system valves, and other LFG collection components across two landfill sites. The initial contract term is 24 months, with potential extensions for up to three additional one-year terms, anticipated to start around August 1, 2025. Proposal evaluation will be based on four primary criteria: approach, value/cost of service, assigned staff/team experience, and references/past performance. Key deadlines include proposal questions due by June 12, 2025, and final electronic proposals due by July 17, 2025, at 4:00 pm. The RFP requires proposers to submit separate technical and cost proposals, with specific certification requirements including independent contractor status and compliance with child support obligations.

The RFP does not explicitly specify set-aside designations or restrictions for disadvantaged enterprises. The Kiefer Landfill currently collects approximately 7,500 CFM of landfill gas, feeding two gas destruction flares and two gas-to-energy plants, while the Elk Grove Landfill collects around 110 CFM, treated through a granular activated carbon system. The County reserves the right to award multiple contracts and will consider trade-offs between proposed cost and evaluation criteria. While specific budget ranges are not detailed, the contract will require review by County Counsel and approval by the Board of Supervisors, with no binding obligations until final ratification. The procurement includes a Proprietary Information Agreement to protect confidential information submitted during the proposal process, and proposers must be prepared to provide comprehensive documentation of their technical capabilities, labor rates, and potential markup fees for materials and equipment rentals.
