BENDER READY-MIX CONCRETE MANUFACTURING PROJECT <br />Initial Study/Mitigated Negative Declaration <br />4.3 AIR QUALITY <br /> <br /> <br /> <br /> <br /> <br />t <br /> <br />PA <br /> <br /> <br /> <br />Where available, the significance criteria established by the Less Than <br /> <br />applicable air quality management or air pollution control otentially <br />P Significant Less Than <br />No <br />dlstrcf may be relied upon to make the following Significant <br />Impact ImpactWith:_ <br />:Mitigation Significant <br />Impact Impact <br />determinations. Would the project: Incorporated <br />a. Conflict with or obstruct implementation of the applicable air <br />quality plan? <br />b. Violate any air quality standard or contribute substantially to <br />an existing or projected air quality violation? <br />c. Result in a cumulatively considerable net increase of any <br />criteria pollutant for which the project region is non-attainment <br />under an applicable federal or state ambient air quality <br />standard (including releasing emissions which exceed <br />quantitative thresholds for ozone precursors)? <br />d. Expose sensitive receptors to substantial pollutant <br />concentrations? <br />e. Create objectionable odors affecting a substantial number of <br />people? <br />a) Conflict with or obstruct implementation of the applicable air quality plan? <br />Less Than Significant Impact <br />According to the CEQA Air Quality Handbook, in order to determine consistency with the South Coast <br />Air Quality Management District (SCAQMD) Air Quality Management Plan (AQMP) two main criteria <br />must be addressed. <br />Criterion 1: <br />With respect to the first criterion, SCAQMD methodologies require that an air quality analysis for a <br />project include forecasts of project emissions in relation to contributing to air quality violations and delay <br />of attainment. <br />a) Would the project result in an increase in the frequency or severity of existing air qualify <br />violations? <br />Since the consistency criteria identified under the first criterion pertain to pollutant <br />concentrations, rather than to total regional emissions, an analysis of the project's pollutant <br />emissions relative to localized pollutant concentrations is used as the basis for evaluating <br />project consistency. As discussed in Response 4.3(d), below, localized concentrations of CO, <br />NOx, PM,o, and PM2.5 would be less than significant. Therefore, the proposed project would <br />not result in an increase in the frequency or severity of existing air quality violations. Because <br />ROGs are not a criteria pollutant, there is no ambient standard or localized threshold for <br />ROGs. Due to the role ROG plays in ozone formation, it is classified as a precursor pollutant <br />and only a regional emissions threshold has been established. <br /> <br />JULY 2011 4.3-1 AIR QUALITY <br />31A-39
