TA. - Page 59 <br />Summary of Impacts <br />Potentially Less than Significant Less an <br />Significant With Mitigation Significthant No <br />Impact Incorporated Impact Impact <br />III. AIR QUALITY -- Would the project: <br />a) Conflict with or obstruct implementation of the applicable air quality plan? <br />b) Violate any air quality standard or contribute substantially to an existing or <br />projected air quality violation? <br />c) Result in a cumulatively considerable net increase of any criteria pollutant for <br />which the project region is non -attainment under an applicable federal or state <br />ambient air quality standard, including releasing emissions that exceed <br />quantitative threshold for ozone precursors? <br />d) Expose sensitive receptors to substantial pollutant concentrations, including, <br />but not limited to, substantial levels of toxic air contaminants? <br />e) Create objectionable odors affecting a substantial number of people? <br />Conclusion: Regarding air quality, the proposed project would not result in any new significant environmental impacts or a <br />substantial increase in the severity of previously identified significant impacts (CEQA Guidelines Section 15162(a)). All <br />impacts are adequately evaluated in the certified Downtown Precise Plan program EIR. The proposed project is also <br />consistent with the Downtown Precise Plan (CEQA Guidelines Section 15183). <br />Documentation: <br />a. & b. The Downtown Precise Plan program EIR (pp. 12-17 and 12-18) concluded that development occurring in <br />conformance with the DTPP would be consistent with the Bay Area Air Quality Management District (BAAQA4D) <br />2010 Clean Air Plan control measures and the BAAQMD CEQA Air Quality Guidelines because the projected rate <br />of increase in new vehicle trips resulting from the DTPP would be less than the associated projected rate of <br />population growth. Therefore, the impact of the DTPP was considered to be less than significant, and no mitigations <br />were required. The proposed project is in compliance with all applicable DTPP standards, and as a result, no <br />additional air quality impacts are anticipated. Standard City requirements and BAAQMD-recommended procedures <br />to minimize construction air emissions (e.g., properly tuned equipment subject to on-site monitoring, idling time <br />limits) shall be required as conditions ofproject approval. <br />c. The Downtown Precise Plan program EIR identified carbon monoxide (CO) as the pollutant of greatest concern in <br />the Bay Area region. CO levels in the Bay Area are well below ambient air quality standards, and there have been <br />no exceedances of CO standards in the Bay Area since 1991. However, localized high concentrations of CO can <br />occur near busy congested intersections. According to the BAAQMD screening methodology, DTPP buildout would <br />not cause traffic volumes at affected intersections to exceed CO thresholds, and the impact of development resulting <br />from the DTPP would be less than significant; therefore, no mitigations were required. (EIR p. 12-18) The proposed <br />project is in compliance with all applicable DTPP standards, and as a result, no additional criteria air pollutant <br />impacts are anticipated. <br />d. The DTPP program EIR (pp. 12-18 through 12-20) concluded that development in accordance with the DTPP <br />standards would expose sensitive receptors to toxic air contaminants (IACs) and particulates (PM2.5) if located <br />within 500 feet of the Caltrain railroad, El Camino Real, or Veterans Boulevard. The approximate distances from <br />the project site to these facilities are as follows: the Caltrain railroad — 1,340 feet; El Camino Real — 1,920 feet; <br />and Veterans Boulevard — 690 feet. Because the project site is more than 500 feet from the Caltrain railroad, El <br />Camino Real, and Veterans Boulevard, Impact 12-1 ('Toxic Air Contaminant and PM2.5 Exposure Impacts) would <br />not occur, and EIR Mitigation 12-1 is not required. <br />e. The ground floor retail component of the project is intended to accommodate a bank; if the use is changed to <br />include food service businesses, then DTPP EIR Mitigation 12-2 shall be required. The mitigation, which is the <br />same as DTPP regulation 2.2.2.1.g, requires the project to implement odor -reducing measures consistent with the <br />BAAQMD CEQA Air Quality Guidelines, including, for example, integral grease filtration or grease removal <br />systems, baffle filters, activated carbon filters, oxidizing pellet beds, and exhaust stack and ventilation location with <br />respect to receptors. The mitigation, which would be subject to City review and approval, shall be required as a <br />condition of project approval - should the proposed bank use change to include a food service business - to reduce <br />12 <br />X <br />X <br />►.4 <br />X <br />X <br />
