On October 8, 2021, EGLE-AQD inspectors conducted an announced compliance inspection of the Arbor Hills Energy LLC facility (the gas-to-energy operation at the Arbor Hills Landfill). The inspection focused on ambient air testing for methane and hydrogen sulfide and discovered significant undocumented landfill gas emissions from multiple sources on the treatment and turbine building roofs, including a passive sewer vent measuring 129,000 ppm methane and H2S exceeding 50 ppm, and cooling vents on the turbine building roof emitting up to 1,500 ppm methane. The inspectors concluded that the amount and concentration of landfill gas detected was beyond expectations and concerning, and noted that condensate volumes processed through the treatment building have grown dramatically from under 50,000 gallons per month in 2018 to over 350,000–450,000 gallons per month by mid-2021.
Key data point: Methane measured at 129,000 ppm from condensate sump passive vent on treatment building roof; H2S exceeded 50 ppm detection limit (both unquantified); 1,500 ppm methane from Turbine 2 cooling vent; condensate volume increased from <50k gal/month (2018) to 350k–450k gal/month (2021). October 8, 2021.
