Countryside Genco, LLC. (Genco) operates a facility that generates electricity using engines that combust landfill gas from neighboring Countryside Landfill. GencoÂs sulfur dioxide emissions were discovered to have significantly increased after higher than expected concentrations of hydrogen sulfide were found to be present in the landfill gas. The elevated hydrogen sulfide levels found in the landfill gas was caused by the disposal of processed construction and demolition debris by Countryside Landfill.
To address these elevated emissions, Genco has applied to Illinois Environmental Protection Agency to modify their facilityÂs permitted sulfur dioxide levels. In this Administrative Order, Genco also agrees to undertake a regular monitoring program to assess the concentration of hydrogen sulfide in the landfill gas used by its facility, as well as a robust preventative maintenance program in order to decrease the potential for incidents where the facility would have to be off-line.
