CITY OF SAN LEANDRO <br />RE: Exhibit A -CONSISTENCY MEMORANDUM FOR THE SLTC MIXED-USE PROJECT (PLN16-0067) <br />JULY 17, 2017 <br />Page 18 <br /> <br />Construction and Air Quality Impacts <br />Construction activities would produce combustion emissions from various sources, such as on-site heavy- <br />duty construction vehicles, vehicles hauling materials to and from the site, and motor vehicles <br />transporting the construction crew. Site preparation activities would produce fugitive dust emissions <br />(PM10 and PM2.5) from demolition and soil-disturbing activities, such as grading and excavation. Air <br />pollutant emissions from construction activities on-site would vary daily as construction activity levels <br />change. Construction activities associated with the proposed project would result in emissions of reactive <br />organic gases (ROG), nitrogen oxides (NOx), carbon monoxide (CO), and PM10 and PM2.5. <br />To determine potential construction-related air quality impacts, criteria air pollutants generated by <br />project-related construction activities for the entire Scenario 3 are compared to the BAAQMD <br />significance thresholds. Average daily emissions are based on the annual construction emissions divided <br />by the total number of active construction days. As outlined in Table 5, criteria air pollutant emissions <br />from construction equipment exhaust would not exceed the BAAQMD average daily thresholds. <br />Table 5 <br />Maximum Daily Construction Emissions Summary (Pounds per Day) <br />Construction <br />Emissions ROG NOx Exhaust <br />PM10 <br />Exhaust <br />PM2.5 <br />Fugitive Dust <br />PM10 <br />Fugitive Dust <br />PM2.5 <br />Maximum Daily <br />Emissions 10.51 29.64 1.69 1.57 1.86 0.50 <br />BAAQMD Potentially <br />Significant Impact <br />Threshold <br />54 54 82 54 <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Basic <br />Construction <br />Mitigation <br />Measures <br />Exceed BAAQMD <br />Threshold? No No No No No No <br />Source: CalEEMod version 2016.3.1. See Appendix A for emission model outputs. <br />As shown in Table 4 above, projected emissions for the full SLTC would fall below the construction- <br />related significance thresholds developed by the Bay Area Air Quality Management District (BAAQMD), <br />the air pollution control officer for the region. Therefore, as the project represents only a fraction of SLTC <br />buildout, project emissions would also fall below BAAQMD thresholds. The project would not exceed the <br />buildout proposed in the TOD Strategy and analyzed in the TOD Strategy EIR. The TOD Strategy EIR <br />found that construction-related criteria pollutant emissions from exhaust associated with TOD Strategy <br />buildout would be less than significant. Thus, no further analysis is needed, and the project is consistent <br />with the City’s TOD Strategy EIR. <br /> <br />164
