With implementation of mitigation measure <br />AQ-1, the proposed project's emissions from construction will be reduced and <br />will not exceed the SCAQMD localized thresholds of significance. <br />The emissions from area sources including consumer products such as home <br />' appliances, lawnmowers, water heaters, and stoves can generate a significant <br />amount of pollutants. Furthermore, mobile sources from vehicles traveling in and <br />out of the proposed project also emit pollutants. The area and mobile source <br />emissions, including daily trips were analyzed for the proposed project and <br />presented in the table below. <br /> <br /> <br /> <br /> <br /> <br /> <br />Table 3 -Daily Operational Emissions -Regional Significance <br /> ROG NOx CO SOZ PMIO PMZ.S COZ <br /> (Ibs/da) (lbs/da) (lbs/da) (Ibs/da) (lbs/da) (Ibs/da) (lbs/da ) <br />SCAQMD 55 55 550 150 150 55 N/A <br />Threshold <br />Summer 15.18 19.91 194.38 0.18 26.67 5.54 17,248.62 <br />Max <br />Emissions <br />Winter Max 16.82 24.08 183.36 0.14 28.66 5.53 15,620.85 <br />Emissions <br />Exceed No No No No No No No <br />Threshold? <br />Source: Air Quali Anal sis Technical Memorandum, URS Co oration.
