Pennsylvania Department of Environmental Protection (PADEP) – Ozone Transport Commission
The state of Pennsylvania is part of the Ozone Transport Commission (OTC), therefore projects outside the named nonattainment areas in state that exceed 100 tons of NOx and VOC may be required to offset their emissions with Emission Reduction Credits.

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, VOC, PM10 or SOx 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.
