  PROFESSIONAL EXPERIENCE

Mr. McCarron has over 20 years of progressively responsible experience in solid waste management, including landfill gas (LFG) systems, landfill design, waste composition studies, recycling, composting, transfer stations, and waste-to-energy systems. His experience includes project management, design, regulatory support, construction oversight, system start-up, economic analysis, and technology assessment. 

Since joining SCS in 1990, he has worked primarily on LFG control and recovery projects.  He is the Office Director of SCS's New York office, and he is the leader of the New York office Landfill Gas Group.

Mr. McCarron directs LFG migration investigations; designs and prepares plans, specifications, cost estimates and operation and maintenance (O&M) manuals for LFG migration and odor control, and LFG recovery projects; provides regulatory support, including permit applications, NSPS and Title V reporting and compliance; and provides construction oversight, system start-up, and trouble-shooting. Designs have included LFG recovery systems; active control systems in or adjacent to landfills; passive control systems adjacent to landfills; and systems to protect buildings located adjacent to or on landfills.  He has designed more than 30 LFG migration control, odor control and recovery systems. Representative projects include:
