AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY <br /> 12956 <br />DUDEK 20 April 2022 <br />3.3 Air Quality <br /> <br />Potentially <br />Significant <br />Impact <br />Less Than <br />Significant <br />Impact With <br />Mitigation <br />Incorporated <br />Less Than <br />Significant <br />Impact No Impact <br />III. AIR QUALITY – Where available, the significance criteria established by the applicable air quality <br />management district or air pollution control district may be relied upon to make the following <br />determinations. Would the project: <br />a) Conflict with or obstruct implementation <br />of the applicable air quality plan? <br />b) Result in a cumulatively considerable <br />net increase of any criteria pollutant for <br />which the project region is non- <br />attainment under an applicable federal <br />or state ambient air quality standard? <br /> <br />c) Expose sensitive receptors to <br />substantial pollutant concentrations? <br />d) Result in other emissions (such as those <br />leading to odors) adversely affecting a <br />substantial number of people? <br /> <br />Setting <br />The project property is located within the jurisdiction of the Bay Area Air Quality Management District <br />(BAAQMD) and within the San Francisco Bay Area Air Basin (SFBAAB). The SFAAAB is designated non- <br />attainment for the federal 8-hour ozone (O3) and 24-hour PM2.5 standards. The area is in attainment or <br />unclassified for all other federal standards. The area is designated non-attainment for State standards for <br />1-hour and 8-hour O3, 24-hour PM10, annual PM10, and annual PM2.5. The significance thresholds utilized <br />in this analysis to evaluate air quality impacts are based on the BAAQMD thresholds established in the <br />BAAQMD CEQA Air Quality Guidelines (BAAQMD 2017a), as summarized in Table 3.3-1 below. <br />Table 3.3-1.
