GFL Environmental requests a pre-application meeting with EGLE regarding remediation of PFOS contamination in a 3.78-acre wetland at Arbor Hills Landfill. The contamination resulted from a November 2016 fire at an on-site recycling facility that was extinguished using AFFF foam containing PFOS. GFL proposes to dewater, excavate impacted soils to 1.5–2 feet, fill with clean material to 5 feet, and restore the site to non-wetland conditions while providing mitigation elsewhere.

Emerald RNG LLC responds to EGLE's formal request for details on a methane-recording device malfunction that caused a long-duration ROP deviation affecting actual emissions. The company explains that a coupling leak in the sample supply line diluted methane readings, implemented corrective actions (coupling repair, monthly verification checks, new SCADA alarm), and updated its PM/MAP plan to prevent recurrence.
Key data point: Methane recording device malfunction caused by sample-line coupling leak leading to inaccurate (diluted) methane readings; device repaired and corrective measures implemented including monthly verification checks and low-methane SCADA alarm.
