Draft Supplemental Environmental Impact Report Page VIII-13 Forward Inc.Landfill 2018 Expansion Project used in the ambient air quality analysis is available in the AQIA by SCS Engineers(See Appendix G 14). " The Air Quality Impact Assessment(AQIA) (DSEIR Appendix G),which was the basis for the air quality evaluations) calculated the impact of criteria pollutants and presented them in Table 3-17. The AQIA has been revised in response to other SJVAPCD comments, and the revised AQIA is included as Appendix G of the FEIR. Impacts greater than the Significant Impact Level (SIL)established by the SJVAPCD, CEQA thresholds,or impacts that result in a new exceedance of the AAQS would be considered significant. TAs described in revised Mitigation Measure IV.D-2,below,the applicant will be required to mitigate any such significant impacts to a level that is less than significant, to the satisfaction of the SJVAPCD and San Joaquin County. The implementation of this measure will be monitored by the County as described in the Mitigation Monitoring and Reporting Program. The revised dispersion modeling conducted for the Final SEIR(in response to SJCAPCD comments) also found that at Future Permitted levels (640 truck trips per day)PM10 and PM2.5 would contribute to background concentrations that exceed the NAAQS and CAAQS(the same impact as identified in the DSEIR).The revised AAQS results are presented in Table 1,below.
