City of San Leandro 2824 Halcyon Drive Residential Project 30 Table 6 Construction Emissions (pounds/day) Pollutant Average Daily Emissions (Unmitigated) Significance Threshold Significant Impact? ROG 2 54 No NOx 7 54 No CO 8 N/A N/A PM10 (exhaust) <1 82 No PM2.5 (exhaust) <1 54 No Notes: ROG = reactive organic gases; NOX = oxides of nitrogen; CO = carbon monoxide; PM2.5 = fine particulate matter with an aerodynamic resistance diameter of 2.5 micrometers or less; PM10 = respirable particulate matter with an aerodynamic resistance diameter of 10 micrometers or less. N/A = not applicable; no BAAQMD threshold for CO or SOX. Average daily emissions were calculated using Table 2.1 “Overall Construction-Unmitigated” annual emissions in tons per year converted to pounds per day using the days of construction (246 days) calculated using the Section 3.0 “Construction Detail” “Construction Phase” table in the CalEEMod worksheet. Source: Appendix AQ, CalEEMod worksheet Table 2.1 “Overall Construction-Unmitigated” emissions. As shown in Table 6, the proposed project would not exceed the BAAQMD short-term construction thresholds shown in Table 5. In addition, implementation of Mitigation Measure AQ-2B-1 requiring the project to comply with the BAAQMD-recommended BMPs to reduce fugitive dust-related impacts would further reduce construction emission impacts. Furthermore, as mentioned under Section 12, Best Management Practices, of the Project Description, the project would be required to comply with COA AQ-1 and utilize low emitting construction equipment to minimize emissions. Impacts from construction emissions would therefore be less than significant with mitigation identified in the General Plan EIR and Uniformly Applicable Development Policies. Operational Emissions Long-term emissions associated with operational impacts, as shown in Table 7 and Table 8, would include emissions from vehicle trips (mobile sources), natural gas and electricity use (energy sources), and landscape maintenance equipment, consumer products, and architectural coating associated with on-site development (area sources). Current emissions from the site’s existing uses were not subtracted from project emissions to provide a conservative analysis.
