► result in a cumulatively considerable net increase of any criteria pollutant for which the project region is <br /> nonattainment under an applicable NAAQS or CAAQS (including releasing emissions which exceed <br /> quantitative thresholds for ozone precursors), <br /> ► expose sensitive receptors to substantial pollutant concentrations, or <br /> ► create objectionable odors affecting a substantial number or people. <br /> As stated in Appendix G,the significance criteria established by the applicable air quality management or air <br /> pollution control district may be relied upon to make the above determinations. Thus, as identified by SJVAPCD, <br /> implementation of the proposed project would result in significant air quality impacts if(SJVAPCD 2002): <br /> ► SJVAPCD-recommended control measures beyond compliance with Regulation VIII-Fugitive Dust <br /> Prohibition are not incorporated into project design or implemented during project construction; <br /> ► construction-related emissions of ROG or NOx exceed the SJVAPCD-recommended mass emissions <br /> threshold of 10 tpy; <br /> ► long-term operational(regional) emissions of ROG or NOx exceed the SJVAPCD-recommended mass <br /> emissions threshold of 10 tpy; <br /> ► long-term operational(local)mobile-source emissions of CO violate or contribute substantially to a violation <br /> of the NAAQS or CAAQS; <br /> ► exposure of sensitive receptors to a substantial incremental increase in TAC emissions(e.g., stationary or <br /> mobile-source)that exceed 10 chances per million for excess cancer risk and/or a hazard Index of 1 for <br /> noncancer risk at the Maximally Exposed Individual (MEI); or <br /> ► sensitive receptors would be located near an existing odor source where one confirmed complaint per year <br /> averaged over a three year period,or three unconfirmed complaints per year averaged over a three year period <br /> has been experienced by existing receptors as close as the project to the odor source; or by existing receptors <br /> in the vicinity of a similar facility considering distance, frequency, and odor control,where there is currently <br /> no nearby development and for proposed odor sources near existing receptors. <br /> IMPACT ANALYSIS <br /> IMPACT Air Quality—Generation of Short-Term Construction-Related Emissions of Criteria Air Pollutants <br /> 4.3-1 and Precursors.Modeled short-term project-generated emissions from construction equipment for projects <br /> constructed during Phase 1 (2008 to 2010 based on construction projections presented in Table 3-4) would <br /> exceed SJVAPCD's significance threshold of 10 tpy and project applicable SJVAPCD-required and other <br /> control measures for fugitive dust are not currently part of the project description. Project-generated, <br /> construction-related emissions of criteria air pollutants and precursors could violate or contribute <br /> substantially to an existing or projected air quality violation, expose sensitive receptors to substantial <br /> pollutant concentrations, especially considering the nonattainment status of San Joaquin County, and/or <br /> conflict with air quality planning efforts.As a result, this impact would be a significant. <br /> Construction-related emissions are described as"short-term"or temporary in duration and have the potential to <br /> represent a significant impact with respect to air quality, especially fugitive PMIo dust emissions. Fugitive PMIo <br /> dust emissions are primarily associated with site preparation and vary as a function of such parameters as soil silt <br /> content, soil moisture,wind speed, acreage of disturbance area, and vehicle miles traveled(VMT)by construction <br /> vehicles on-and off-site. Ozone precursor emissions of ROG and NOx are primarily associated with gas and <br /> diesel equipment exhaust and the application of architectural coatings. <br /> Manteca WQCF and Collection System Master Plans EIR EDAW <br /> City of Manteca 4.3-19 Air Quality <br />
