City of Pleasanton—Vineyard Avenue Residential Project 15183 Consistency Checklist Consistency Checklist 39 have an adverse effect on air quality. As the SFBAAB is currently designated as a nonattainment area for PM, and considering that the BAAQMD’s recommended significance threshold for construction fugitive dust is binary— meaning if a project includes dust control BMPs then construction fugitive dust emissions would be less than significant, but if a project does not explicitly include dust control BMPs then construction fugitive dust emissions would be potentially significant—MM AIR-1a would be required to ensure that individual development projects facilitated by the Housing Element Update would result in less than significant construction fugitive dust impacts. As previously discussed in Impact III(a), by complying with the AQP and implementation of MM AIR-1a and -1b, operational related criteria pollutant emissions would not have an adverse effect on air quality. Therefore, the Housing Element Update FEIR concluded that, with the implementation of MM AIR-1a and 1b, a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State ambient air quality standard would not occur and impacts would be less than significant. Proposed Project Analysis and Conclusion According to the AQ/GHG Assessment, the Bay Area is considered a non- attainment area for ground-level ozone (O3) and particulate matter 2.5 microns in diameter (PM2.5) under both the national ambient air quality standard (NAAQS) and the California ambient air quality standard (CAAQS). The area is also considered non-attainment for PM10 under the CAAQS, but not the NAAQS. The area has attained both State and federal ambient air quality standards (AAQS) for carbon monoxide (CO). As part of an effort to attain and maintain AAQS for ozone (O3), PM2.5, and PM10, BAAQMD has established thresholds of significance for these air pollutants and their precursors. The O3 precursor pollutant thresholds are for reactive organic gases (ROG) and nitrous oxides (NOX), while PM10 and PM2.5 have specific thresholds. The thresholds apply to both construction period emissions and operational period emissions. All development projects within the jurisdiction of the BAAQMD are required to implement BAAQMD’s Basic Construction Mitigation Measures (BCMMs). The City’s standard procedure is to include compliance with the BAAQMD BCMMs through MM AIR-1a or as Conditions of Approval, including the following:
