Building Construction Pollutant Unmitigated (Ibs/day) SCAQMD Threshold ROG 1.69 75 NOx 11.73 100 CO 12.77 550 PM10 0.76 150 S02 0.01 150 PM2.e 0.69 55 C02 2,217.67 N/A Bold-underline indicates exceedance of SCAQMD Threshold. Architectural Coatings The architectural coatings phase was based on work taking place over the last 45 days of construction. Additional decreases in ROG (VOC) can be obtained by using High Velocity Low Pressure Applicators and NO VOC coatings. As shown in the table below, no thresholds were exceed for this phase of construction. Architectural Coatings Pollutant Unmitigated (Ibs/day) SCAQMD Threshold ROG 66,67 75 NOx 0.04 100 CO 0.71 550 PM10 0.01 150 S02 0.00 150 PM2s 0.00 55 C02 96.71 N/A Bold-underline indicates exceedance of SCAQMD Threshold. Construction Emissions Conclusion The Air Quality Assessment concludes that with no exceedances of the significance thresholds, predicted emissions would be considered to have a less than significant impact during the construction phase of the project. The FEIR concluded that construction activity impacts will exceed the significance thresholds for ROG (architectural coatings) and a Statement of Overriding Considerations was adopted. This portion of the project will not exceed emissions and no significant impact will occur. Area Emissions The Area Emissions include emissions from the day-to-day operation and maintenance of the facilities, consumer products usage, natural gas use and landscaping equipment use. URBEMIS default values were used with no mitigation measures used in the model. Traffic data was obtained from the KOA Corporation Traffic Impact Study dated December 2010. As shown in the table below, there will be no significant increase in criteria pollutants due to the project. MacArthur Place South EIR - 2011 Addendum 23 75B-68
