This is an nForm emissions compliance document filed November 6, 2025, containing nitrogen oxides (NO2) and sulfur dioxide (SO2) test results from four gas turbine units (Typhoon Turbines 1–3 and Solar Turbine GT4) at what appears to be a waste-to-energy or landfill gas facility. The measured pollutant concentrations are reported against federal and Michigan air pollution control standards.
Key data point: Nitrogen oxides measured at Typhoon Turbines 1–3 in the range of 190–240 ppmvd@15%O2, with three-run averages ranging from 28.1 to 38.6 ppmvd@15%O2; sulfur dioxide measured at 0–0.41 lb/hr and 0–0.15 lb/mmbtu across regulated units.

This nForm document reports nitrogen oxides (NO2) and sulfur dioxide emissions test results from four gas turbines (Typhoon GT1-GT3 and Solar Turbine GT4) at an industrial facility, measured using EPA-approved methods. All reported NO2 concentrations range from approximately 28 to 39 ppmvd@15% O2, and sulfur dioxide emissions are reported at 0.1–0.41 lb/hr or 0.15 lb/mmbtu, well below permit limits.
Key data point: NO2 emissions measured across four turbines: 28–39 ppmvd@15%O2 (average per run); SO2 emissions ≤0.41 lb/hr; all compliance tests conducted per 40 CFR Part 60 Subparts GG and KKKK.
