Environmental Checklist Air Quality Final Initial Study – Negative Declaration 31 3 Air Quality Potentially Significant Impact Less than Significant with Mitigation Incorporated Less than Significant Impact No Impact Would the project: a. Conflict with or obstruct implementation of the applicable air quality plan? □ □ □ ■ b. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? □ □ ■ □ c. Expose sensitive receptors to substantial pollutant concentrations? □ □ ■ □ d. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? □ □ □ ■ a. Would the project conflict with or obstruct implementation of the applicable air quality plan? The federal Clean Air Act (CAA) governs air quality in the United States and is administered by the U.S. EPA at the federal level. Air quality in California is also governed by regulations under the California CAA, which is administered by CARB at the State level. At the regional and local levels, local air districts typically administer the federal and California CAA. As part of implementing the federal and California CAA, the U.S. EPA and CARB have established ambient air quality standards for major pollutants at thresholds intended to protect public health. Pleasanton is located within the San Francisco Bay Area Air Basin (the Air Basin), which includes the nine Bay Area counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southwestern Solano, and southern Sonoma. The Air Basin is under the jurisdiction of the Bay Area Air Quality Management District (BAAQMD). As the local air quality management agency, BAAQMD is required to monitor air pollutant levels to ensure that State and federal air quality standards are met and, if they are not met, to develop strategies to meet the standards. Depending on whether or not the standards are met or exceeded, the Air Basin is classified as being in “attainment” or “nonattainment.” Under State law, air districts are required to prepare a plan for air quality improvement for pollutants for which the district is in non-attainment. BAAQMD is in non- attainment for the State and federal ozone standards, the State and federal PM2.5 (particulate matter up to 2.5 microns in size) standards, and the State PM10 (particulate matter up to 10 microns in size) standards and is required to prepare a plan for improvement.27 The sources, health effects, and typical controls associated with criteria pollutants are described in Appendix A. 27 Bay Area Air Quality Management District (BAAQMD). 2017.
