This is a Request for Proposals (RFP) #RFP194618 issued by the City of Palo Alto Public Works Department for landfill gas and leachate control systems monitoring, reporting, and well installation services. The city is seeking a qualified consultant to perform services for its closed class III municipal solid waste landfill located at 2380 Embarcadero Road for a 5-year term. The proposal submission deadline is Monday, July 21, 2025 before 3:00 pm, with potential consultant interviews scheduled for August 14, 2025. The project involves comprehensive monitoring and reporting of the landfill's gas collection environmental control systems, including 91 vertical gas extraction wells, 24 leachate extraction wells, and 11 condensate sumps, with potential expansion of leachate wells during the contract period.
The contract will be structured as a Not-To-Exceed Budget Per Task form, with progress payments based on percentage of project completed. Proposers must provide evidence of financial stability through options like audited financial statements, reviewed financial statements, or a letter of good standing from a financial institution.

5. SCOPE OF WORK
5.1. LANDFILL GAS AND LEACHATE CONTROL SYSTEMS MONITORING,
REPORTING, AND WELL INSTALLATION SERVICES
Purpose of This Scope of Services:
Through this Request for Proposals (RFP), the City of Palo Alto (CITY) is seeking a qualified and experienced firm (“CONSULTANT”) to perform monitoring and reporting services for the CITY Landfill’s gas collection environmental control systems (landfill gas and leachate collection systems) for a term of 5 years.
Background:
History and Phasing: The CITY owns and operates an unlined, class III municipal solid waste disposal site, located at 2380 Embarcadero Road in Palo Alto, California. The landfill reached refuse capacity and ceased accepting waste in 2011 and underwent final capping and regulatory closure in 2015. The landfill occupies approximately 126 acres of the 1800-acre, CITY owned Byxbee Park and Baylands parcel. The landfill is divided into phases - Phase I, Phase IIA, Phase IIB, and Phase IIC, based on the timing of closure and conversion to parkland. Phase I comprises approximately 29 acres and was closed and developed into parkland in 1990. Phases IIA (23 acres), IIB (24 acres) and IIC (51 acres) were closed and converted to parkland in 1992, 2000 and 2015 respectively. Smaller areas of the landfill are occasionally closed off to park users on an as-needed basis for control system maintenance and settlement repairs.
The environmental control systems within the landfill consist of a vertical landfill gas extraction system and a retrofitted vertical leachate extraction system.
Landfill Gas System: The CITY’s landfill gas (LFG) collection system consists of 91 vertical extraction wells. Most of the gas wells are spaced approximately 200 feet apart, have been constructed with 4 to 6-inch diameter Schedule 40 PVC casings or high-density polyethylene (HDPE) casings placed within 24-inch diameter boreholes and have an average depth of approximately 35 feet below the landfill surface. An HDPE piping network collects and transmits gas from the extraction wells to a blower-flare facility where it is combusted. The blower-flare facility is located on Palo Alto Regional Water Quality Control Plant (PARWQCP) property near the landfill northwest boundary. The pipe network is below grade throughout the landfill facility, buried within the final cover system.
In the Phases that were capped with a clay layer (Phase I, IIA, IIB), the gas collection system pipes are buried above the clay cap within a thickened vegetative soil layer. In
Request for Proposal (RFP) #RFP194618 10
Phase IIC the pipes are buried within a 4-ft thick layer of evapotranspirative cover material.
Currently, 5 leachate wells are connected to the gas collection system due to the detection of methane above regulatory limits inside and/or outside those wells. During the term of this contract, the CITY may elect to place an additional 18 leachate wells under vacuum and add them to the landfill gas collection system. Any monitoring required under the regulations of landfill gas wells would include those leachate wells that have been hooked up to the landfill gas collection system.
Leachate System: The CITY’s Leachate Collection and Removal System (LCRS) consists of 24 vertical extraction wells. These wells are typically constructed with 6-inch diameter Schedule 80 PVC casings and strategically distributed throughout the landfill. Well spacing averages approximately 300 feet, with locations being selected based upon historic information and local leachate levels at the time of installation. Each well has a dedicated pneumatic pump, and compressed air is delivered to each well from a centrally located compressor via a network of welded HDPE piping. Leachate is collected from the wells and transported via the piping network to the CITY sanitary sewer main adjacent to the western boundary of the landfill.
Leachate elevations within the refuse mass are measured through a set of 17 vertical piezometers.
Condensate Collection: Gas condensate produced by the LFG collection system is collected in sumps and pumped into the facility’s LCRS via pneumatic submersible pumps. There are currently eleven (11) condensate sumps located in Phase I, Phase IIA, Phase IIB and Phase IIC, combined.

B) Annual Source Pre-Test
• In addition to the annual Source Test test, CONSULTANT shall perform an annual source test “pre-test” one day prior to the official source test to identify compliance issues, troubleshoot, and tune the flare as necessary to ensure optimal performance and compliant source test results. The pre-test does not require a report or notification to BAAQMD.
Task 3 – Routine Report Preparation
Task 3 is outlined below and includes report preparation in compliance with Bay Area Air Quality Management District (BAAQMD) Rule 8-34, AB32 Landfill Methane Rule, and EPA Greenhouse Gas Reporting Rule, as listed below.
