Advanced Disposal's April 24, 2019 letter to MDEQ's Air Quality Division responds to an April 11, 2019 Violation Notice alleging NSPS/NESHAP violations at Arbor Hills Landfill's gas wells for exceeding the 131°F wellhead temperature limit without approved Higher Operating Values (HOVs). The letter recounts the history of an 'elevated temperature' hot zone dating to 2016 (per an attached Dec. 2, 2016 AQD HOV approval letter for wells WW284/285/286/258R and oxygen well 320), and discusses AHL's March 28, 2019 HOV request for 13 wells (temperatures requested up to 180°F) that AQD rejected on April 11, 2019. The March 28, 2019 request table shows alarmingly high carbon monoxide at well AHW272R2 (14,400 ppm), far above other wells, alongside discussion of thermogenic decomposition, reduced methane, and risk of pyrolysis/thermal decomposition if heat is not removed.
Key data point: AHW272R2 showed a measured carbon monoxide reading of 14,400 ppm (most recent prior to the 3/28/2019 HOV request), by far the highest of 13 wells in the elevated-temperature area awaiting HOV approval.

The Michigan DEQ issued an Enforcement Notice to Arbor Hills Energy LLC on April 18, 2019, imposing a $5,000 stipulated fine for failure to complete required emission testing (carbon monoxide, sulfur dioxide, nitrogen oxide, volatile organic compounds, and hydrogen chloride) between June 2015 and June 2018 as mandated by a 2015 Consent Order. The notice also announces escalated enforcement action citing multiple High Priority Violations (HPVs) of federal and state air quality standards, including ongoing sulfur dioxide emission limit exceedances, and warns that failure to resolve violations may result in civil litigation.
Key data point: Stipulated fine of $5,000 for failure to complete emission testing required by Consent Order AQD No. 16-2015; multiple High Priority Violations (HPVs) designated by U.S. EPA; ongoing SO2 emission limit exceedances documented in separate EPA Findings of Violation dated September 29, 2016 and June 4, 2018.
