Calculate the by model year LDV idling emission rates by multiplying the 5 MPH Running <br />emission rates by 5 (glinile x mile/hr = g/hr). <br />Therefore emissions are multiplied by a factor of 5 to account for possible idling activities. <br />For 160 miles of in-structure travel, the automotive exhaust pollutants compare to the threshold <br />as follows assuming 90% of vehicles are gas powered and 10% are diesel powered: <br />Pollutant In Structure Emissions Emissions of Concern Impact vs. Threshold <br />At Closest Existing <br />Sensitive Use <br />CO 4.3 lb/hour 263.6 lb/hour 1.6% <br />NOx 0. 5 lb/hour 15.4 lb/hour 3.2% <br />For information, emissions were also compared to the LST standards for a receptor at the closest <br />possible distance from the source and could be indicative of on-site residential exposure as <br />follows: <br />Pollutant In Structure Emissions Emissions of Concern Impact vs. Threshold <br />For On-Site Sensitive <br />Use <br />CO 4.3 lb/hour 60.6 lb/hour 7.1% <br />NOx 0. 5 lb/hour 11.1 lb/hour 4.5% <br />The worst-case CO or N02 exposure to any resident close to the proposed structure is negligible <br />even under the most extreme worst case situation whereby 531 vehicles arrive and 531 vehicles <br />depart in a single hour. Possible peak hour usages rates and associated emissions impact will be <br />much lower.
