As indicated at Table 6, the Proposed Project would result in a net decrease <br />in peak operational -source VOC, NOx, CO, and SOx emissions when compared to peak operational - <br />source criteria pollutant emissions generated by the Currently Approved One Broadway Plaza land <br />uses. It should be noted that Proposed Project would reduce NOx impacts to less than significant levels. <br />Additionally, the Proposed Project would not result in new or substantively different or substantively <br />increased operational -source air quality impacts than the emissions associated with the Currently <br />Approved One Broadway Plaza land uses. <br />TABLE 6: OPERATIONAL EMISSIONS COMPARISON <br />Operational Activities <br />Emissions (lbs/day) <br />VOC <br />NOx <br />CO <br />Sox <br />PM10 <br />PM2.5 <br />Proposed Project <br />18.78 <br />23.16 <br />91.93 <br />0.20 <br />15.61 <br />4.61 <br />Currently Approved One Broadway Plaza Land Uses <br />31.60 <br />76.10 <br />462.20 <br />41.30 <br />8.50 <br />- <br />Variance (Proposed Project — Currently Approved) <br />-12.82 <br />-52.94 <br />370.27 <br />-41.10 <br />-7.11 <br />N/A <br />GHG EMISSIONS COMPARISON <br />Table 7 compares GHG emissions of the Proposed Project with GHG emissions generated by the <br />Currently Approved One Broadway Plaza land uses. As indicated at Table 7, the Proposed Project would <br />result in a net decrease in GHG emissions (approximately 42 percent less). The Proposed Project would <br />therefore not result in new or substantively different or substantively increased GHG emissions <br />impacts than the emissions associated with the Currently Approved One Broadway Plaza land uses. <br />TABLE 7: GHG COMPARISON <br />Emission Source <br />Annual Emissions (MTCO2e) <br />Proposed Project <br />5,795.27 <br />Currently Approved One Broadway Plaza Land Uses <br />10,009.23 <br />Variance (Proposed Project — Currently Approved) <br />-4,213.96 <br />CONCLUSIONS <br />Based on the analysis presented here, air pollutant emissions generated by Proposed Project would <br />not exceed applicable SCAQMD thresholds.
