listed under GPU PEIR MM AQ-1 and AQ-2 are either suggested for industrial uses or do not <br /> directly reduce operational VOC emissions. Therefore, Project-Specific MM AQ-1 would be <br /> implemented to reduce significant impacts related to VOCs during Project operations. <br /> Threshold AQ-3: The Project would not expose sensitive receptors to substantial pollutant <br /> concentrations with the implementation of mitigation. <br /> Findings: The City finds that changes or alterations have been required in, or incorporated into, <br /> the Project, which avoid or substantially lessen the significant environmental effect as identified <br /> in the Final Supplemental EIR. Specifically, the City finds that GPU PEIR MM AQ-1 (listed above) <br /> shall be implemented to reduce potentially significant air quality impacts resulting from the Project. <br /> (Draft Supplemental EIR, p. 4.1-39.) <br /> Explanation of the Rationale: The rationale and facts supporting the above finding are fully <br /> developed in Section 4.1,Air Quality, pages 4.1-42 through 4.1-47 of the Draft Supplemental EIR. <br /> The following presents a summary of that rationale: <br /> The Project would not expose sensitive receptors to substantial pollutant concentrations, including <br /> to significant health risk impacts for residential sensitive receptors during project construction with <br /> the implementation of GPU PEIR MM AQ-1. Pursuant to GPU PEIR MM AQ-1, the Project <br /> requires use of construction equipment rated by the USEPA as having Tier 4 (model year 2008 <br /> or newer) emissions limits, applicable for engines between 50 and 750 horsepower. The total <br /> highest calculated carcinogenic risk would be approximately 7.36 in one million and would not <br /> exceed the SCAQMD threshold of 10 in one million with the implementation of GPU PEIR MM <br /> AQ-1. Therefore, construction activities associated with the Project are not anticipated to result in <br /> a significant cancer or other health risk to nearby sensitive receptors, and, as such, the health <br /> impacts during construction of the Project would be less than significant with <br /> mitigation incorporated. <br /> Further, by complying with GPU PEIR MM AQ-1, the Project would reduce construction-related <br /> DPM emissions and associated acute risk, and the highest maximum chronic and acute hazard <br /> index associated with the mitigated emissions from Project construction at residential sensitive <br /> receptors would be 0.136 and 0.918 and would not exceed the 1.0 chronic hazard index for <br /> individual significance. Therefore, the Project's chronic and acute hazard index would be less <br /> than significant with mitigation incorporated. <br /> Cumulative Impacts: The Project would not result in cumulative impacts concerning air quality <br /> with the implementation of mitigation. <br /> Findings: The City finds that changes or alterations have been required in, or incorporated into, <br /> the Project, which avoid or substantially lessen the significant environmental effect as identified <br /> in the Final Supplemental EIR. Specifically, the City finds that GPU PEIR MM AQ-1 and Project <br /> Specific MM AQ-1 (listed previously) shall be implemented to reduce potentially significant air <br /> quality impacts resulting from the Project.
