1 1 and Project Mitigation Measure AQ-1 requires the off -road construction equipment greater <br />than 50 horsepower to meet CARE Tier 4 Final emission standards, and Project specific Mitigation <br />Measure AQ-1 provides for construction exhaust and dust controls, construction emissions associated <br />with NOx would remain above the SCAQMDs threshold. <br />Also, Mitigation Measure AQ-3 requires a Transportation Demand Management (TDM) program, <br />Mitigation Measure AQ-4 prohibits fireplaces, and Mitigation Measure AQ-6 requires the Project <br />to use "Super -Compliant" low VOC paints to reduce operational ROG emissions. However, ROG <br />emissions during operation of the Project at buildout would remain above the SCAQMD's threshold. <br />There are no feasible mitigation measures that would reduce NOx and ROG emissions to below <br />the SCAQMD thresholds. Therefore, the proposed Project would result in an impact related to <br />Consistency Criterion No. 2. As a result, impacts related to consistency with the AQMP would be <br />significant and unavoidable. This is consistent with the impacts identified in the GPU FEIR. <br />Overall, despite the proposed Prolect's consistency with SCAG's regional growth forecasts and the <br />GPU buildout of the South Bristol Street Focus Area per the DC-5 designation, the proposed Project <br />would lead to increased regional air quality operational emissions that would exceed thresholds. <br />Therefore, the proposed Project would result in a conflict with, or obstruct, implementation of the <br />AQMP and impacts would be significant and unavoidable after implementation of mitigation <br />measures that are detailed below. This finding is consistent with the findings of the GPU FEIR related <br />to criteria emissions. (Draft Supplemental EIR at pp. 5.1-23 through 5.1-24). <br />Impact Finding: The Project would result in a cumulatively considerable net increase of a criteria <br />pollutant for which the project region is non -attainment under an applicable federal or state <br />ambient air quality standard (Draft Supplemental EIR at p. 5.1-24). <br />Facts in Support of Findings: <br />Construction <br />Draft Supplemental EIR Table 5.1-8 provides the maximum daily unmitigated emissions of criteria <br />air pollutants from construction of Phase 1 of the proposed Project and shows that SCAQMD <br />thresholds would be exceeded for NOx and ROG (VOC). The GPU FEIR Mitigation Measure AQ- <br />1 1 and Project Mitigation Measure AQ-1 requires the off -road construction equipment greater than <br />50 horsepower to meet CARB Tier 4 Final emissions standards in order to reduce diesel exhaust <br />construction emissions. Project specific Mitigation Measure AQ-2 requires the proposed Project to <br />use "Super -Compliant" low VOC paints to reduce ROG emissions to less than significant levels. Draft <br />Supplemental EIR Table 5.1-9 shows that despite the implementation of mitigation, construction <br />emissions associated with NOx during Phase 1 of construction would remain above the SCAQMD's <br />threshold. Therefore, criteria emissions impacts related to construction of Phase 1 would be <br />significant and unavoidable (Draft Supplemental EIR at p. 5.1-24). <br />Overlapping Construction and Operation Emissions. <br />Phase 1 operations + Phase 2 Construction. Phase 1 has the potential to be operational during <br />Phase 2 construction. Draft Supplemental EIR Table 5.1-18 shows the overlapping emissions would <br />exceed SCAQMD threshold for ROG and NOx and that Mitigation Measures AQ-1 through AQ-6 <br />
