AIR QUALITY. Where available, the significance <br /> criteria established by the applicable air quality management <br /> or air pollution control district may be relied upon to make <br /> the following determinations. Would the project: <br /> a) Conflict with or obstruct implementation of the ❑ ❑ • LI <br /> applicable air quality plan? <br /> b) Violate any air quality standard or contribute LI • LI LI <br /> substantially to an existing or projected air quality <br /> violation? <br /> c) Result in a cumulatively considerable net increase of any ❑ L • LI <br /> criteria pollutant for which the project region is non - <br /> attainment under an applicable federal or State ambient <br /> air quality standard (including releasing emissions which <br /> exceed quantitative thresholds for ozone precursors)? <br /> d) Expose sensitive receptors to substantial pollutant LI • 0 D <br /> concentrations? <br /> e) Create objectionable odors affecting a substantial number LI LI • LI <br /> of people? <br /> Affected Environment: <br /> The project site is located within the San Francisco Bay Air Basin (SFBAB) and is within the <br /> jurisdiction of the Bay Area Air Quality Management District (BAAQMD). Within the SFBAB, <br /> ambient air quality standards for ozone, carbon monoxide (CO). nitrogen dioxide (NO2), sulfur <br /> dioxide (SO2). particulate matter (PM1o, PM2 and lead (Pb) have been set by both the State of <br /> California (State) and the federal government. The State has also set standards for sulfate and <br /> visibility. As of July 2007, the SFBAB is under non - attainment status for ozone and particulate matter <br /> (PM and PM for State standards. The SFAB is classified as marginal non - attainment for the <br /> federal ozone 8 -hour standard. <br /> Discussion: <br /> a) Conflict with or obstruct implementation of the applicable air quality plan? <br /> Less Than Significant Impact. An air quality plan describes air pollution control strategies to be <br /> implemented by a city. county, or region classified as a non - attainment area. The main purpose of <br /> an air quality plan is to bring the area into compliance with the requirements of federal and State <br /> air quality standards. To bring the San Francisco Bay Area region into attainment, the Bay Area <br /> Air Quality Management District (BAAQMD) has developed the 2005 Ozone Strategy and the <br /> 2000 Clean Air Plan (CAP). <br /> P:1EGI080110EQA\PredaFINAL IS•MND.doc (03/28/II) 15 <br />
