Michigan Department of Environment, Great Lakes, and Energy (EGLE) - Muskegon Ozone Nonattainment Area
Muskegon County, located along the eastern shoreline of Lake Michigan, is designated as a Marginal nonattainment area under the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS).
Under the federal nonattainment New Source Review (NSR) program, new or modified major stationary sources of ozone precursors—nitrogen oxides (NOx) and volatile organic compounds (VOC)—must obtain Emission Reduction Credits (ERCs) to fully offset proposed emissions increases. The required offset ratio for a Marginal nonattainment area is 1.1 to 1. For example, a facility proposing to emit 100 tons/year of NOx must obtain 110 tons/year of NOx ERCs.
| Pollutant | New Major Source Emission Rates | Major Modification to existing Source |
|---|---|---|
| Nitrogen oxides (NOx) | ≥100 tons/year | ≥40 tons/year |
| Volatile Organic compounds (VOC) | ≥100 tons/year | ≥40 tons/year |
Facilities that were emitting NOx or VOC may be eligible to generate Emission Reduction Credits (ERCs) with a permanent reduction of those emissions generating from a shutdown or installation of control technology or process change.
If your company has a new project that exceeds thresholds or had a facility with permanent reduction of emissions at any level, please reach out to see how Emissions Experts can assist.
