AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY <br /> 3.3 Air Quality <br /> Less Than <br /> Significant <br /> Potentially Impact With Less Than <br /> Significant Mitigation Significant <br /> Impact Incorporated 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 /> 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 /> 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 (03) 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 Os, 24-hour PMso,annual PMso, 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.Air Quality Thresholds of Significance <br /> Construction <br /> Thresholds Operational Thresholds <br /> Average Daily Average Daily Emissions Maximum Annual <br /> Pollutant Emissions lbs da lbs da Emissions tons ear <br /> ROG 54 54 10 <br /> N OX 54 54 10 <br /> PMso 82 (exhaust) 82 15 <br /> PM2.5 54(exhaust) 54 10 <br /> PM10/PM2.5(fugitive Best Management None <br /> dust) Practices <br /> Local CO None 9.0 ppm (8-hour average, 20.0 ppm (1-hour average) <br /> 12956 <br /> DUDEK 20 April 2022 <br />
