AIR QUALITY. Where available, <br /> the significance criteria established by the <br /> applicable air quality management or air <br /> ` pollution control district may be relied <br /> upon to make the following <br /> determinations. Would the project: <br /> a) Conflict with or obstruct El11 F1 11 <br /> implementation of the applicable air ■ �� <br /> quality plan? <br /> b) Violate any air quality standard or ■ <br /> L contribute substantially to an 11 E El 11 <br /> existing or projected air quality <br /> violation? <br /> c) Result in a cumulatively <br /> 6. considerable net increase of any Ll 0 11 11 <br /> criteria pollutant for which the <br /> project region is non-attainment <br /> under an applicable federal or state <br /> has ambient air quality standard <br /> (including releasing emissions <br /> which exceed quantitative <br /> thresholds for ozone precursors)? <br /> d) Expose sensitive receptors to . <br /> substantial pollutant concentrations? 11 El <br /> e) Create objectionable odors affecting ❑ ❑ <br /> a substantial number of people? <br /> I <br /> L SETTING <br /> L The Mountain House Community is located in the San Joaquin Valley Air Basin(SJVAB), <br /> which is under the jurisdiction of the San Joaquin Valley Air Pollution Control District <br /> (SJVAPCD). Pursuant to the California Clean Air Act, California Air Resources Board <br /> (ARB) is required to designate areas of the state as attainment,non-attainment,or <br /> unclassified with respect to applicable standards. <br /> A summary of annual ambient air quality data for the SJVAB for the years 2000 through <br /> L 2003 is presented in Table 4.12-2 of the SPIIIEIR. The SJVAB is currently designated as a <br /> non-attainment area with respect to the state PMIo standards. The attainment designation <br /> L with respect to the PMZ.S has not been determined(EDAW, 2005b). PM is the acronym for <br /> "particulate matter," and the subscripts refer to the maximum diameters of the particles in <br /> microns. The entire SJVAPCD is in serious non-attainment designation for 8-hour ground- <br /> level ozone. The SJVAPCD is working on a plan to reach attainment by 2013 (Hunsaker, <br /> L 2006). <br /> L <br /> L 4-11 <br />
