3.0 ENVIRONMENTAL CHECKLIST <br />City of San Leandro 1388 Bancroft Avenue Project <br />November 2018 Initial Study/Mitigated Negative Declaration <br />3.0-17 <br />TABLE 3.3-4 <br />CONSTRUCTION-RELATED CRITERIA POLLUTANT AND PRECURSOR EMISSIONS – UNMITIGATED <br />Construction Activities <br />Criteria Pollutant and Precursor Emissions (maximum pounds per day) a <br />ROG NOX Exhaust <br />PM10 <br />Exhaust <br />PM2.5 <br />Fugitive Dust <br />PM10 <br />Fugitive Dust <br />PM2.5 <br />2019 maximum daily emissions 1.5 15.8 0.8 0.8 3.5 1.7 <br />2020 maximum daily emissions 9.1 8.5 0.5 0.4 0.4 0.1 <br />Maximum Daily Emissions of All <br />Years of Construction 9.1 15.8 0.8 0.8 3.5 1.7 <br />BAAQMD Potentially Significant <br />Impact Threshold 54 54 82 54 <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Exceed BAAQMD Threshold? No No No No No No <br />Source: CalEEMod version 2016.3.2. See Appendix AQ for emission model outputs. <br />Notes: a. Project construction activities are assumed to occur over a 15-month period. <br />As shown in Table 3.3-4, during construction, unmitigated short-term daily construction <br />emissions would not exceed the BAAQMD significance thresholds. Although unmitigated emissions would not exceed BAAQMD thresholds, the BAAQMD (2017a, Table 8-2) <br />recommends implementation of Basic Construction Mitigation Measures as mitigation for <br />dust and exhaust construction impacts for all projects, regardless of whether construction <br />emissions thresholds would be exceeded. Mitigation measure MM AQ-1 would require implementation of the Basic Construction Mitigation Measures, which would further reduce <br />emissions. In addition, as described in checklist item d) below, mitigation measure MM AQ-2 would require all off-road diesel-powered construction equipment to have EPA- <br />certified Tier 4 engines or have CARB-verified diesel PM exhaust filters. The use of Tier 4 engines or exhaust diesel PM filters would reduce project construction emissions of exhaust <br />PM10, and exhaust PM2.5. Predicted mitigated maximum daily construction-generated <br />emissions for the project are summarized in Table 3.3-5. <br />TABLE 3.3-5 <br />CONSTRUCTION-RELATED CRITERIA POLLUTANT AND PRECURSOR EMISSIONS – MITIGATED <br />Construction Activities <br />Criteria Pollutant and Precursor Emissions (maximum pounds per day) a <br />ROG NOX Exhaust <br />PM10 <br />Exhaust <br />PM2.5 <br />Fugitive Dust <br />PM10 <br />Fugitive Dust <br />PM2.5 <br />2019 maximum daily emissions 1.5 15.8 0.03 0.03 1.6 0.8 <br />2020 maximum daily emissions 9.1 8.5 0.03 0.03 0.4 0.1 <br />Maximum Daily Emissions of All <br />Years of Construction 9.1 15.8 0.03 0.03 1.6 0.8 <br />BAAQMD Potentially Significant <br />Impact Threshold 54 54 82 54 <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Exceed BAAQMD Threshold?
