<br />shown as the sources of the emissions because the pollutants are released to the <br />• atmosphere at these points. <br />All applicable Construction Permit Applications, Title V Operating Permit <br />Applications, Air Pollution Emission Notices, and Compliance Plans will be filed in <br />the manner and within the timeframe required by the CDPHE Air Quality Division. <br />Air Emissions <br />• <br />Maximum estimated annual emissions from the sources of air pollutants listed <br />above for the Piceance Site and the Parachute Site are summarized in Table 8-1. <br />Table 8-1 Yankee Gulch Project Maximum Estimated Annual Emissions. <br /> Emission Source NO, PM HC <br />Site Group (tpy) (tpy) (tpy) <br /> Process Gas <br />Piceance (Combustion Gas) 115.5 0.11 0.57 <br /> Process Gas <br />Parachute (Combustion Gas) 79.1 130.92 0.14 <br /> Secondary <br />Parachute Ventilation 0.0 40.41 0.00 <br /> (Baghouses) <br />Yankee Gulch <br />Project Total 194.6 171.43 0.71 <br />The boilers and emergency generators will have emissions of nitrogen oxides (NOS), <br />which will be controlled through proper combustion control practices. In addition, <br />the generators will emit particulate matter (PM) and hydrocarbons (HC). <br />The Parachute Site dryer scrubber and dryer electrostatic precipitator will produce <br />only process-related particulate emissions. The particulate emissions from the <br />Parachute Site secondary ventilation dust collectors are less than the standards for <br />Non-Metallic Mineral Processing. For all emission units, the anticipated emission <br />levels of pollutants other than NOS, PM, and HC will be insignificant. <br />Projected Air Ouality Impacts <br />America Soda is currently modeling the air quality impacts from the proposed <br />Yankee Gulch Project according to U.S. Environmental Protection Agency (EPA) and <br />State of Colorado modeling guidance. The modeling analyses will be conducted for <br />• NO, and PM,o emissions from the generators and boilers and for PM,o emissions <br />from the dryer, baghouses, and storage bins.
