Tetra Tech provides landfill gas collection and control system (LFGCCS) operations and monitoring (O&M) services and Title V surface gas emissions monitoring at the Middlesex County Landfill.
NAES Corporation operates a 24/7 landfill gas-to-energy facility in Sayreville, New Jersey, with a gross design capacity of 15 megawatts. The facility minimizes impact to the atmosphere and generates the required electricity to power their wastewater treatment plant, resulting in large monetary savings.
Tetra Tech provides routine and non-routine work activities, including wellfield monitoring and balancing; blower, flare station, dewatering pump, and hydrogen sulfide treatment system monitoring and maintenance; collection of flare flows and LFG quality; and LFG sample collection for regulatory compliance. Our team also provides surface emissions monitoring (SEM), landfill cover integrity monitoring, and responds to emergency callouts as needed.
Benefits
- Provides Title V surface gas emissions monitoring
- Upholds 24/7 emergency response services
LFG is extracted from the Middlesex County Landfill (an active landfill) and ILR Landfill (a closed landfill). The Middlesex County Landfill gas collection system contains numerous vertical gas extraction wells, horizontal collectors, and surface collectors connected to high-density polyethylene (HDPE) header pipes. The LFG collected is pulled through the main compressor and dryer station and delivered through a pipeline and booster station to the LFG energy recovery facility approximately six miles away. The ILR Landfill has an LFG collection system consisting of vertical extraction wells connected to HDPE header pipes. The LFG is extracted and pulled through a gas delivery system that is interconnected to the Middlesex County Landfill gas pipeline.
Our technical knowledge of the site’s GCCS and immediate attention and repairs to its deficiencies, minimizes LFG migration and odors and maximizes LFG collection and power generation while maintaining regulatory compliance.
Your quick response to incidents and identifying the issues in a timely manner has immensely helped the COGEN plant to become more reliable.
