LFG Migration and Emission Control Investigation, System Design, and Permitting

Typical Tasks Performed:

• LFG field investigations
• Identify regulatory requirements
• Installation and monitoring of gas probes
• Migration control plans
• Installation and operation of emergency interim controls
• Design and permitting of migration control systems
• Construction cost estimatesConstruction observations, review of contractor documents, and inspections as owner’s agentSystem troubleshootingExpert testimony
• Containment of subsurface landfill fires, and emergency response

Many SCS projects have entailed hazard assessment and design of active or passive LFG control systems. 

Representative projects include:

• Engineering Evaluation of Existing LFG Control System and Design Improvements, Titcomb Pit, Amesbury, Massachusetts.
   
• LFG Control and Utilization at Parkway Center, Pittsburgh, Pennsylvania.
   

• Perimeter Air Injection Systems (Air Curtains), various clients and locations, including Long Beach, Modesto, Burbank, Commerce, and San Diego, California.

• Perimeter Collection Well Field (in native soil), Lees Lane Landfill, Louisville, Kentucky.

• LFG Low-Vacuum Curtin Control System Design and Installation, Rigsby Avenue Landfill, San Antonio, Texas.

• Evaluation of Existing LFG Control System and Flare and Design Improvements, Lanchester Landfill, Pennsylvania.

• Protection systems for a prison situated near a closed landfill, including air injection, extraction, ventilation and sensor detection systems, Lorton, Virginia.

• Perimeter LFG Collection and Flaring Systems in Thurston County, Washington; Cumberland County, North Carolina; and numerous sites in California, Florida, Ohio, and other states.

• Protection systems for buildings on or near landfills, including membrane barriers, subfloor ventilation, alarm systems, and utility protection throughout the United States.

• Methane Monitoring and Safety Plan preparation/implementation, and control system design for a prison complex, Rikers Island, New York.

• Development of LFG Management Strategies at 15 landfills in New Zealand.
