Mr. Mitchell is a Project Manager with CEC, who has 13 years of experience in solid waste engineering. He has engineering experience associated with the design, permitting, and construction of municipal and residual waste disposal, transfer, and processing facilities. He has managed or performed design and/or permitting services for the solid waste industry to include preparation of permit drawings, landfill construction plans and details; analyses and design of landfill liner systems; analyses and design of erosion and sedimentation control systems; slope stability analysis of soils and geosynthetic systems; analysis of solid waste landfill gas (LFG) generation, collection and control systems; and leachate collection, control, storage; and pumping systems. Mr. Mitchell has experience in the preparation of technical specifications for the procurement, installation, and testing of multi-layer geosynthetic/soil landfill liner and cap systems, and large earthworks. He has managed and/or performed construction observations and certification of numerous landfill construction projects related to soil geosynthetic liner system materials; cap systems; leachate collection, pumping and storage systems; gas extraction systems; and erosion and sedimentation control systems. He has prepared regulatory documentation, including record drawings and reports, for approval of state environmental agencies. Additionally, he has provided various engineering support services to waste industry clients including managing and performing forensic investigations for waste mass slope failures.

Mr. Metzler is a registered Engineer-In-Training in the Commonwealth of Pennsylvania with 8 years of experience in solid waste engineering. He is a graduate of The Pennsylvania State University with a Bachelor's Degree in Civil and Environmental Engineering. He has been responsible for the preparation and completion of permit application packages, calculations, reports, drawings, and other related documentation for submittal to clients and regulatory agencies for municipal and residual waste facilities. Zach has lead construction quality assurance efforts on numerous landfill construction projects related to soil and geosynthetic liner system materials; closure systems; leachate collection, pumping and storage systems; and gas extraction systems. Zach has gained expertise in the installation and maintenance of subsurface monitoring equipment, particularly in relation to supporting the excavation of coal combustion residual materials at several power plants across the Southeastern United States.

Mr. Nagy is a Project Consultant with over 3 years of experience within the solid waste and environmental fields. His experience includes slope stability analysis, slope monitoring instrumentation, landfill construction and design, and environmental compliance. He has diverse field work experience including, but not limited to, instrumentation installation and upkeep, construction quality assurance, drilling oversight, and environmental groundwater and soils sampling. He has also been involved in technical engineering and reporting of slope stability analyses and instrumentation, landfill design, solid waste and environmental permitting, and computer modeling.
