WSP-CA-Landfill Gas Services

Projects

CITY OF MENLO PARK

Project Location: Menlo Park, California WSP has and is currently providing a broad range of engineering and environmental monitoring services to the City Menlo Park. Landfill Gas System Operation and Maintenance: WSP provides comprehensive services for landfill gas collection and control systems (GCCS), supporting both operational reliability and regulatory compliance at Bedwell Bayfront Park Landfill in Menlo Park. Our scope includes routine system maintenance, performance monitoring, and full-spectrum compliance management. Scope of Services Alarm Response & Repairs: WSP responds promptly to system alarms and performs minor repairs on condensate sump components, laterals, headers, extraction wells, and leachate pumps. For example, at Bedwell Bayfront Landfill Park (BBLP), we addressed flare shutdowns due to utility disruptions and conducted maintenance on flow sensors to minimize downtime Monitoring & Reporting: We conduct surface emissions monitoring and perimeter landfill gas assessments. Monthly and annual reports are prepared in accordance with Bay Area Air Quality Management District (BAAQMD) Rule 8-34-113 and other applicable regulations. In June 2025, our team documented flare operation metrics, wellhead oxygen levels, and positive pressure conditions,

recommending liquid level adjustments to restore vacuum conditions Regulatory Alignment & Compliance: All activities are performed in compliance with local, state, and federal environmental regulations. Our work supports clients like the City of Menlo Park and Oakland Public Works in meeting their long-term trash reduction plans and stormwater program requirements Client Engagement & Communication: WSP maintains active communication with city officials and project stakeholders. For instance, we coordinated with Ciara Shirey and Kaila Jones to finalize and submit monthly O&M reports and gas data logs Landfill Gas Collection and Control System Improvements: In 2021, WSP provided engineering support services for the improvement of the GCCS at BBLP. WSP developed improvements for the gas extraction wells and ancillary piping. The improvements included: permitting and providing construction plans and specs, bid assistance and construction management for replacing 500 feet of vertical LFG extraction wells, 6,000 feet of HDPE pipe, 46 wellheads, 81 vaults, and 12 leachate sump pumps, control panels, and ancillary piping.
