Nitrogen Oxides SIP Call Transition Requirements for Large Non Electrical Generating Units
Nitrogen Oxides SIP Call Transition Requirements for Large Non Electrical Generating Units
The “Final Revision to the North Carolina State Implementation Plan (SIP) - Nitrogen Oxides SIP Call Transition Requirements for Large Non Electrical Generating Units with Clean Air Act Section 110(l) Non-Interference Demonstration” was submitted to the United States Environmental Protection Agency (EPA) on July 20, 2016.
The purpose of this SIP revision is to remove 40 CFR Part 75 monitoring, record keeping, and reporting requirements for Non Electrical Generating Units (non-EGUs) that were included in the nitrogen oxide (NOx) Budget Trading Program but excluded from the Cross-State Air Pollution Rule federal trading program. Based on EPA findings showing that the NOx SIP Call requirements have been achieved without any emission reductions from the active large non-EGUs and North Carolina’s demonstration showing that modeled and actual emissions will not interfere with the attainment and maintenance of National Ambient Air Quality Standards in North Carolina and neighboring states, the Division of Air Quality (DAQ) believes that Part 75 requirements for existing non-EGUs are unnecessary, not beneficial and not cost-effective. The DAQ commits to calculate ozone season NOx emissions and assure that the total for the non-EGU group remains below the NOx SIP Call budget by utilizing existing applicable reporting requirements contained in the current operating permit of the non-EGU source.
