The majority of emissions associated with Area and Operational Emissions are generally due to vehicle exhaust emissions. All such emissions would be below the SCAQMD's significance thresholds. Therefore, combined emissions for the project would be considered to have a less than significant impact on regional air quality. a) Would the project conflict with or obstruct implementation of the applicable air quality attainment plan or congestion management plan? (No Substantial Change from Previous Analysis) The City requires projects to conform to population and traffic forecasts contained in the General Plan. The SCAQMD Air Quality Management Plan (AQMP) provides a basis for assessing air quality with the SCAB and provides for pollutant control strategies. The AQMP is used in establishing the State Implementation Plan (SIP) consistent with the requirements of the 1990 Clean Air Act Amendments (CAAA). The SIP defines how the SCAB will achieve the federal ambient air quality standards. Because the project is not projected to increase the population or traffic conditions beyond what is forecast in the General Plan, regional emissions associated with the project are accounted for within the AQMP and are, therefore, consistent with the AQMP. The project will not conflict with or obstruct implementation of the air quality attainment plan or congestion management plan and no impact will occur. b) Would the project violate any stationary source air quality standard or contribute to an existing or proposed air quality violation? (No Substantial Change from Previous Analysis) As indicated above, the Air Quality Assessment concluded that the proposed modification to the project as originally approved will not exceed air quality thresholds. However, the air quality analysis in the EIR noted that construction activity impacts for the originally approved project will exceed significance thresholds for RDG due to the application of architectural coatings. This was considered an unmitigable impact and a statement of overriding considerations was adopted in 2005. The proposed modification to the original project will not violate any stationary source air quality standards or contribute to an existing or proposed air quality violation. Therefore, the FEIR remains adequate and complete. c) Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non - attainment under an applicable federal or state ambient air quality standard (including releasing emission which exceeds quantitative thresholds for ozone precursors? (No Substantial Change from Previous Analysis) As identified in the FEIR, construction related emissions would exceed the applicable South Coast Air Quality Management District thresholds. The air quality impacts from the project as originally proposed, plus air quality impacts from related cumulative projects and buildout of the City's General Plan, would contribute additional emissions, resulting in an impact that is significant and cannot be MacArthur Place South EIR — 2011 Addendum 24
