unavoidable. Construction of the Proposed Project would occur within the building envelope of the Approved <br />Project and would not expand the building footprint nor require additional grading or excavation. Thus, the <br />Proposed Project's construction related air quality emissions would be within the scope of analysis of the <br />Approved Project identified in the Certified EIR. The Proposed Project would further incorporate all applicable <br />mitigation measures identified in the Certified EIR. Therefore, the Proposed Project would not create a new <br />significant impact or a substantial increase in the severity of previously identified effects. <br />Table 4, Proposed Pryect Operational Emission Summary, shows that the operational emissions of the Proposed <br />Project. The Proposed Project's operational emissions would not exceed the regional thresholds of significance <br />established by the SCAQAM for any criteria emissions. <br />Table 4 Proposed Project Operational Emission Summary <br />Operational Activities - Summer <br />Scenario <br />Emissions (pounds per day) <br />VOC <br />N0, <br />CO <br />SO. <br />PMio <br />PMzs <br />Area <br />12.98 <br />0.39 <br />33.31 <br />1.75E-03 <br />0.18 <br />0.18 <br />Energy <br />0.35 <br />3.11 <br />2.13 <br />0.02 <br />0.24 <br />0.24 <br />Mobile <br />5.84 <br />20.70 <br />59.56 <br />0.19 <br />16.35 <br />4.50 <br />Total Maximum Daly Emissions <br />19.18 <br />24.20 <br />94.99 <br />0.22 <br />16.77 <br />4.93 <br />SCAQMD Regional Threshold <br />55 <br />55 <br />550 <br />150 <br />150 <br />55 <br />Threshold Exceeded? <br />NO <br />NO <br />NO <br />NO <br />NO <br />NO <br />Operational Activities -Winter <br />Scenario <br />Emissions (pounds per day) <br />VOC <br />NO. <br />CO <br />SO. <br />PMio <br />PMzs <br />Area <br />12.98 <br />0.39 <br />33.31 <br />1.75E-03 <br />0.18 <br />0.18 <br />Energy <br />0.35 <br />3.11 <br />2.13 <br />0.02 <br />0.24 <br />0.24 <br />Mobile <br />5.76 <br />21.13 <br />58.61 <br />0.19 <br />16.35 <br />4.50 <br />Total Maximum Daily Emissions <br />19.10 <br />24.63 <br />94.05 <br />0.21 <br />16.77 <br />4.93 <br />SCAQMD Regional Threshold <br />55 <br />55 <br />550 <br />150 <br />150 <br />55 <br />Threshold Exceeded? <br />NO <br />NO <br />NO <br />NO <br />NO <br />NO <br />Further, Table 5, Operational Emission Comparison, compares peak operational source criteria pollutant emissions <br />generated by the Proposed Project with peak operational source criteria pollutant emissions generated by the <br />Currently Approved One Broadway Plaza land uses. As indicated at Table 5, the Proposed Project would result <br />in a net decrease in peak operational -source VOC, NOx, CO, and SOx emissions when compared to peak <br />operational -source criteria pollutant emissions generated by the Currently Approved One Broadway Plaza land <br />uses. The Certified EIR disclosed that operational NO, emissions from the Approved Project would be <br />significant and unavoidable. With the Proposed Project, NOx impacts would be reduced to a less than <br />significant level. The Proposed Project's operation au quality emissions would be less than significant. The <br />Proposed Project would reduce the significant and unavoidable impact relating to operational NO. to a less <br />than significant level. Therefore, the Proposed Project would not create a new significantimpact or a substantial <br />increase in the severity of previously identified effects. The Proposed Project would further incorporate all <br />applicable mitigation measures identified in the Certified ElIL The Proposed Project would not require major <br />revisions to the Certified EIR. <br />75A-90 <br />
