Potential Significant Effect The project, in combination with the other existing and planned cumulative projects within the planning area, could create cumulatively significant air quality impacts due to total cumulative project emissions. Description of Specific Impact The Project site is located in the San Joaquin Valley Air Basin(SJVAB), where air quality conditions are regulated by the SJVAPCD. The emissions would be cumulatively significant if, with mitigation, there remains any increase in a pollutant for which the SJVAB is classified as a nonattainment area. The SJVAB is in nonattainment for PMIo,PM2.5, and ozone. All of the proposed Project and other.cumulative project components that contribute to potential emissions from their operation are summarized below as the net emissions increase after mitigation is applied. Near term and long term scenarios are presented, since the impact significance varies with each scenario. The near term total cumulative projects mitigated NOx emissions are 267.06 tpy. The near term total cumulative projects mitigated VOC emissions are 132.05 tpy. The near term total cumulative projects mitigated particulate matter emissions of PMIo are 244.01 tpy, and the near term mitigated emissions of PM2.5 are 57.57 tpy. The long term total cumulative projects mitigated particulate matter emissions of PMIo are 339.14 tpy,and the long term mitigated emissions of PM2.5 are 93.07 tpy. The long term total cumulative projects mitigated NOx emissions are 301.24 tpy. The long term total cumulative projects mitigated VOC emissions are 159.58 tpy. The long term total cumulative projects mitigated CO emissions are 232.15 tpy. As presented in the Draft EIR, although the cumulative and Project level impacts have been lessened to the extent feasible by the design features, imposition of all reasonable and applicable mitigation measures, and the SJVAPCD's rules and regulations, including Regulation VIII, the proposed project as described and evaluated against the background of the serious existing conditions of the air basin will remain significant and unavoidable. The near term scenario cumulative project operational impacts will remain significant and unavoidable for emissions of NOx, VOC and PMIo. The long term scenario cumulative projects operational impacts will remain significant and unavoidable for emissions of NOx, VOC, CO, and PMio. Finding The cumulative air quality impact from total cumulative project emissions is considered significant and unavoidable. All feasible and reasonable changes or alterations have been required in, or incorporated into,the project that substantially lessen the potentially significant effect as identified in the Final EIR. Brief Explanation of the Rationale for the Finding CEQA requires that all feasible and reasonable mitigation be applied to the project to reduce the impacts from total cumulative project emissions on air quality. Implementation of Mitigation Measures 4.1-1, 4.1-2, 4.1-3, 4.1-4, 4.1-5, 4.1-6, and 4.1-7 would reduce total cumulative project emissions. No other reasonable or feasible mitigation has been identified that will reduce impacts to air quality for the project. The cumulative air quality impact is considered significant and unavoidable. -----.___..-_..- --- ...__...._____..__._._.._. ... __..._.__._......_._.........._._...- --...._._.............-...._._......_...._..._....._......... ......-.---.._...--- - -..__...
