3.0 ENVIRONMENTAL CHECKLIST As shown in Table 3.3-5, during construction, mitigated short-term daily emissions would not exceed the BAAQMD significance thresholds. Long -Term (Operational Phase) Air Quality Impacts The project would result in long-term operational emissions of criteria air pollutants and ozone precursors (i.e., ROG, NOX, PMio, and PM2.5). Project -generated increases in emissions would be predominantly associated with motor vehicle use, energy required for commercial and residential building operations, energy used due to water consumption, energy used in solid waste collection and disposal, and area sources such hearths and use of landscaping equipment. Per the BAAQMD (2017a), if the project meets the screening criteria in Table 3-1 of the district's CEQA Air Quality Guidelines, the project operations would not generate criteria air pollutants and/or precursors in amounts that would exceed the thresholds of significance. Project operation would therefore result in a less than significant impact on air quality from criteria air pollutant and precursor emissions (BAAQMD 2017a). Table 3-1 of the BAAQMD guidelines indicates a mid -rise apartments screening level size for operational emissions of 494 dwelling units. The proposed project would construct only 45 apartments. Therefore, the project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation. The impact would be less than significant. With implementation of mitigation measure MM AQ-1, the project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation. The impact would be less than significant with mitigation incorporated. c) Less Than Significant Impact. Past, present, and future development projects contribute to the region's adverse air quality impacts on a cumulative basis. According to the BAAQMD, no single project is sufficient in size, by itself, to result in nonattainment of ambient air quality standards. Instead, a project's individual emissions contribute to existing conditions. In developing thresholds of significance for air pollutants, the BAAQMD considered the emissions levels for which a project's individual emissions would be cumulatively considerable. According to the BAAQMD (2017a), if a project's emissions exceed the district's identified significance thresholds, the impact on air quality would be cumulatively considerable. As discussed in checklist item b) above, the project's construction and operational emissions would be below the BAAQMD thresholds. Therefore, the project would not result in a cumulatively considerable net increase of criteria pollutants and this impact would be less than cumulatively considerable. d) Less Than Significant Impact with Mitigation Incorporated. Short -Term Construction Toxic Air Contaminants The project site is adjacent to residential neighborhoods and a school. Project construction would generate diesel PM emissions from the use of off -road diesel equipment required for demolition, site grading, excavation, and other construction activities. Diesel PM is the primary TAC that would be emitted during construction. Health -related risks associated with diesel -exhaust emissions are primarily linked to long-term exposure and the associated risk of contracting cancer. The amount to which the receptors could be exposed, which is a function of concentration and duration of exposure, is the primary factor used to determine health risk. 1388 Bancroft Avenue Project Initial Study/Mitigated Negative Declaration City of San Leandro November 2018 3.0-18
