Wednesday, September 2021
Join EREF, Ohio EPA, and industry leaders who will cover emerging topics in landfill management with a focus on:
The Summit will take place at the Marriott Columbus University Area in Columbus, Ohio. Rooms are $119 per night.
As with many EREF events, this will likely fill to capacity quickly.

EREF, the Ohio EPA, and industry leaders will discuss the latest science, factors, and best practices around landfill instability. This session will include managing liquids and leachate and the practice of aqueous waste disposal in landfills.
The Summit will take place at the Marriott Columbus University Area in Columbus, Ohio, on September 1, 2021. As with many EREF events, this will likely fill to capacity quickly.
SCS Engineers President and CEO Jim Walsh will moderate the Elevated Temperature Landfills session. This informative session will include mechanisms contributing to elevated temperatures, modeling to predict and control those conditions, and monitoring and management. Mr. Walsh is well-regarded for his expertise with ETLF conditions. His firm, SCS Engineers, produces the technology used to monitor and manage over one-third of the landfills in the U.S., alerting operators of landfill conditions 24/7 in real-time.
About Jim Walsh: He is one of SCS’s National Experts on Elevated Temperature Landfills working at the forefront of sustainable solid waste management, sanitary landfills, and landfill gas (LFG) for more than 40 years. Mr. Walsh earned recognition as the Principal Investigator or Chief Engineer on over thirty dedicated landfill fire and elevated temperature landfill projects. He regularly guides landfill operators and the solid waste industry on how to avoid landfill fires. He has investigated landfill fires in-situ and developed management and mitigation programs to address landfill fires and related events when they do occur. He served on the Ohio EPA Committee to address landfill fires and elevated temperature landfills in the state and assisted in developing the Ohio EPA Guidance Document on the subject.
