1420 Landcaster-Newark Rd NE Walnut Twp., OH 43046
Permit Description
Initial Installation permit-to-install (PTI) for a new natural gas fired electric generating facility utilizing simple cycle turbines.
The proposed allowable emission rates of PSD pollutants from the facility in tons per year are: Nitrogen Oxides (NOX) 485.8; Carbon Monoxide (CO) 687.1; Volatile Organic Compounds (VOC) 218.3; Particulate Matter (PM) 334.2; PM less than or equal to 10 microns (PM10) 333.4; PM less than or equal to 2.5 microns (PM2.5) 333.3; Sulfur Dioxide (SO2) 86.5; Sulfuric Acid (H2SO4) mist 19.1; Greenhouse Gas/Carbon Dioxide equivalent 7,232,826.
Air dispersion modeling was performed to show allowed emission levels will not cause or contribute to an exceedance of any National Ambient Air Quality Standard (NAAQS). The maximum air pollutant concentrations and averaging periods that are expected from this facility are the following in micrograms per cubic meter: 7.30 nitrogen dioxide (NO2) 1-hour, 0.26 NO2 annual; 567.69 CO 1-hour; 312.18 CO 8-hour; 2.97 PM10 24-hour; 1.90 PM2.5 24-hour; 0.14 PM2.5 annual; 2.94 SO2 1-hour; 2.52 SO2 3-hour; 0.87 SO2 24-hour; and 0.05 SO2 annual. Air dispersion modeling was also performed to evaluate potentially toxic compounds and passed all toxic modeling thresholds. All other pollutants were too small to model.
The permit is available to view through Ohio EPA's eDoc system. Launch the form and search for the permit by entering the Entity Name or Permit/Package Number: P0140492.
