Odor Evaluation

EGLE conducted a drive-by odor evaluation of Arbor Hills Landfill on February 22, 2025, in response to odor complaints and a reported vacuum loss issue. Inspectors detected light to moderate gas odors along Napier and 6 Mile Roads, with methane readings of 10–20 ppm near the compost driveway and flagpole area, and up to 7 ppm in residential zones. Moderate leachate odors were also noted near railroad-track leachate tanks, with all three flares operating, suggesting the RNG plant was offline.

Key data point: Methane readings 10–20 ppm between compost driveway and flagpole on 6 Mile Road (Feb 22, 2025); highest residential reading 7 ppm; levels of 20 ppm or above would be consistent with Rule 901 odor violations.

Letter outlining alternate GG testing criteria

EPA approves Corteva Agriscience's request to conduct NOx performance testing of two gas turbines at Harbor Beach, MI at peak load only (97% capacity) rather than at four evenly-spaced load points, based on historical data showing the turbines operate within a narrow 95–100% capacity window. The approval is conditional on triplicate testing, load-data record-keeping, and reporting of any operating deviations outside 95–105% capacity for 6+ hours.

Key data point: Corteva turbines operate at 95–100% capacity; EPA approves single peak-load test point at 97% capacity instead of four evenly-spaced load points under 40 C.F.R. § 60.335(b)(2).

The document details inadequate daily cover, massive leachate pooling, erosion, and haphazard waste placement as root causes, while describing Republic's aggressive corrective actions including 31 new wells, 22 replaced wells, expedited repairs, and daily odor monitoring.

Key data point: No specific quantitative readings of temperature, CO, oxygen, or other environmental parameters are provided. The document contains operational narrative and photographs of problems but no measured data points.
