Environmental Checklist Greenhouse Gas Emissions Environmental Consistency Checklist Pursuant to CEQA Guidelines Section 15183 57 safeguard public health by reducing exposure to air pollutants that pose the greatest health risk, and reduce GHG emissions to protect the climate. As described in Section 3, Air Quality, the 2017 Plan is based on anticipated population and growth estimates included in the General Plan. The project would involve construction of 18 residential units on an infill site, consistent with the goals of the General Plan regarding efficient strategic growth; therefore, the project is consistent with the 2017 Plan. In the context of global GHG emissions, most individual projects do not generate sufficient GHG emissions to create a project-specific impact through a direct influence on climate change. Therefore, the issue of climate change typically involves an analysis of whether a project’s contribution towards an impact is cumulatively considerable. “Cumulatively considerable” means the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, other current projects, and probable future projects (CEQA Guidelines Section 15355). BAAQMD has evaluated regional GHG emissions in context of Statewide emissions and developed guidance for local agencies on how to determine the significance of project operational-related GHG emissions relative to the cumulative statewide emissions. According to BAAQMD guidance, the GHG emission threshold should be 1,100 metric tons per year of CO2e (MT CO2e/yr), or 4.6 MT CO2e/yr per service population (residents and employees) for land use development projects within the Basin (BAAQMD 2017b). Additionally, according to BAAQMD, if a project is consistent with an adopted qualified GHG reduction strategy that addresses the project’s GHG emissions, it can be presumed that the project would not have significant GHG emission impacts (BAAQMD 2017b). The City of San Leandro’s 2021 CAP was adopted in July 2021. The CAP is consistent with BAAQMD’s requirements for a qualified GHG reduction strategy. Therefore, project consistency with the City’s CAP would be indicative of the project not having significant GHG emission impacts. FCS conducted an Air Quality and Greenhouse Gas Emissions and Energy Impacts Constraints Analysis for the project (included as Appendix AQ). FCS’ analysis involved running CalEEMod version 2020.4.0 based on applicant-provided information and comparing the CalEEMod outputs to BAAQMD thresholds. a.Would the project generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment? Project construction would generate temporary short-term GHG emissions through travel to and from the worksite and from the operation of construction equipment such as graders, backhoes, and generators. Site preparation and grading typically generate the greatest amount of emissions due to the use of grading equipment and soil hauling. Construction activity would generate approximately 175 MT CO2e which, amortized over 30 years, would be approximately 5.8 MT CO2e per year (Appendix AQ). BAAQMD has not identified applicable construction GHG threshold, thus this calculation is included for informational purposes. Nonetheless, the project applicant would be required to comply with applicable BAAQMD rules and regulations regarding emission control measures. Table 10 shows the project’s estimated operational GHG emissions, which would be approximately 357 MT CO2e per year with the primary source of emissions from mobile sources and energy use (Appendix AQ). This would be below the BAAQMD significance threshold of 1,100 MT CO2e per year.
