43  Installation of electric power lines during early construction phases to avoid use of diesel generators, welders, and compressors,  Use of electrically powered equipment,  Forklifts and aerial lifts used for exterior and interior building construction shall be electric or propane/natural gas powered,  Change in construction build-out plans to lengthen phases, and  Implementation of different building techniques that result in less diesel equipment usage. Such a construction operations plan would be subject to review by an air quality expert and approved by the City prior to construction.” With implementation of these HRA-recommended construction-period measures, subject to City review and approval, emission levels for cancerogenic risk would be reduced to below the BAAQMD thresholds and the Housing Component’s cancer risk would be reduced to a level below the single-source threshold. Emissions would also not exceed the cumulative-source thresholds. The Housing Component’s exposure of sensitive receptors to substantial pollutant concentrations would be reduced to a less-than-significant level. Potential for Cumulative Impacts Illingworth & Rodkin (pp. 20-27) evaluated cumulative health risks due to the Housing Component’s location and proximity to existing permitted stationary TAC sources, such as freeways or highways, busy surface streets, and stationary sources identified by BAAQMD. Illingworth & Rodkin identified existing health risks from El Camino Real, Woodside Road, Caltrain, UPRR, and three existing stationary sources of TACs with the potential to affect the project maximally exposed individual (MEI). According to BAAQMD Permitted Stationary Source 2021 GIS data, three existing sources were identified using this tool, one diesel generator and two gasoline-dispensing facilities. Based on BAAQMD screening data estimates, the results of the Illingworth & Rodkin analysis determined that the combined sources for cancer risk, maximum annual PM2.5 concentration, and Hazard Index (HI) would not exceed BAAQMD cumulative source thresholds, though as discussed previously in the HRA the project’s unmitigated construction maximum cancer risk and annual PM2.5 concentration would exceed the BAAQMD single-source thresholds and would require implementation of the measures identified previously to reduce emissions to a level below the single-source threshold. With implementation of Focused GPU program EIR Mitigation Measure AIR-2, the Housing Component’s exposure of sensitive receptors to substantial pollutant concentrations would be reduced to a less-than-significant level. Therefore, the Housing Component would be consistent with the analysis of the Focused GPU EIR because it would not create new impacts or increase impacts and there is no new information of substantial importance for CEQA purposes. Onsite Health Risk Assessment of TAC Sources - New Project Receptors (related informational item) Although not required by CEQA, Illingworth & Rodkin also prepared an assessment of the impact that existing TAC sources would have on the new residents of the proposed project component (sensitive receptors). Illingworth & Rodkin used the same TAC sources identified in the previous analysis. The results of this analysis (pp. 28-30) determined that cancer risk, maximum annual PM2.5 concentration, and HI would not exceed BAAQMD single-source or cumulative source thresholds for new residents. d. With respect to construction period odors, the Focused GPU program EIR (pp. 4.3-25 and 4.3-26) determined that odors resulting from construction, such as odors from fuel combustion or solvents/paints, would be temporary, would quickly disperse, and would not affect a substantial number of people. The Focused GPU program EIR determined that land uses under the Focused GPU would not result in land uses associated with odor complaints (such as agricultural operations, wastewater treatment plants, landfills, and certain industrial operations. Therefore, it found the potential impacts to be less than significant. The Housing Component does not propose a food service business or other restaurant use. This Component would accommodate residential refuse and recycling in an enclosed trash room adjacent to the garage within the building (southeast). Waste service trucks would pull into the fire lane to a collection area with a concrete loading pad (Plan Sheet G302, 10/6/23). Refuse and recycling pick-up would be provided by a local waste service provider (Recology) and would occur on a weekly basis. No substantial odor impacts are anticipated as a result of the Housing Component because: (1) the component’s trash room would be fully enclosed within the building, and (2) trash would be picked- up on a regular schedule. With respect to construction period odors, the Focused GPU program EIR (pp. 4.3-25 and 4.3-26) determined that odors resulting from construction, such as odors from fuel combustion or solvents/paints, ATTY/RESO.0028/CC RESO CEQA GUIDLINES (920 SHASTA) - EXHIBIT A REV: 04-22-25 VR Page 43 of 148
