Therefore, project construction <br /> would result in a less than significant impact. <br /> Operational Emissions <br /> The proposed project would generate operational emissions principally from vehicle traffic accessing <br /> the site. The proposed project's trip generation during operation is taken from Urban Crossroads' <br /> Santa Ana Rezone Trip Generation Assessment (Appendix E). For conservative analysis, the <br /> project's vehicle fleet mix has not been adjusted to reflect that the majority of vehicles accessing the <br /> EV charging station portion of the proposed project would be electric vehicles that would not generate <br /> emissions. The following analysis relates to localized and regional criteria pollutant impacts. <br /> Emissions resulting from various aspects of the proposed project are discussed separately below. <br /> The proposed project's maximum daily operations emissions are shown and compared with the <br /> significance thresholds in Table 2, <br /> FCS 31 <br /> N41P5://dtlecinnovatierns.sharepoint.cam/sales/Publicalinna5it@/Shar@dD—ments/Pub1ications/Cf6ent IPN-JNI/03Z7JC3270047/ISMND/03770047 Santa Ana Rein.PrnQr4WaDce No. NS-3092 <br /> Page 43 of 118 <br />
