SAN LEANDRO SHORELINE DEVELOPMENT DRAFT EIR <br />CITY OF SAN LEANDRO <br />AIR QUALITY <br />■ The Project involves construction of new residential units and new commercial and recreational <br />facilities, and is therefore not a major source of operational TACs and stationary PM2.5. BAAQMD <br />thresholds related to siting new sources of TACs and PM2.5 near existing or planned sensitive receptors <br />is not applicable. <br />The Project is a sensitive land use that would warrant an on-site community risk and hazards <br />evaluation. Therefore, the community risk and hazards thresholds for operation of the Project are <br />applicable. <br />The thresholds identified below are applied to the Project's operational phase (siting new receptors) and <br />construction emissions: <br />Community Risk and Hazards — Project <br />Project -level emissions of TACs or PM2.5 from individual sources within 1,000 feet of the Project that <br />exceed any of the thresholds listed below are considered a potentially significant community health risk: <br />■ Non-compliance with a qualified Community Risk Reduction Plan; <br />■ An excess cancer risk level of more than 10 in one million, or a non -cancer (i.e., chronic or acute) <br />hazard index greater than 1.0 would be a significant cumulatively considerable contribution; <br />■ An incremental increase of greater than 0.3 micrograms per cubic meter (µg/m) annual average <br />PM2.5 from a single source would be a significant cumulatively considerable contribution.'' <br />Community Risk and Hazards — Cumulative <br />Cumulative sources represent the combined total risk values of each of the individual sources within the <br />1,000 -foot evaluation zone. A project would have a cumulative considerable impact if the aggregate total <br />of all past, present, and foreseeable future sources within a 1,000 -foot radius from the fence line of a <br />source or location of a receptor, plus the contribution from the Project, exceeds the following: <br />■ Non-compliance with a qualified Community Risk Reduction Plan; or <br />■ An excess cancer risk levels of more than 100 in one million or a chronic non -cancer hazard index <br />(from all local sources) greater than 10.0; or <br />W 0.8 µg/m3 annual average PM2.5- 36 <br />Cor' <br />The BAAQMD's thresholds for odors are qualitative. The BAAQMD does not consider odors generated <br />from use of construction equipment and activities to be objectionable. For operational phase odor <br />impacts, a project that would result in the siting of a new source of odor or exposure of a new receptor to <br />existing or planned odor sources should consider odor impacts. The BAAQMD considers potential odor <br />impacts to be significant if there are five confirmed complaints per year from a facility, averaged over <br />three years. The BAAQMD has established odor screening thresholds for land uses that have the potential <br />Bay Area Air Quality Management District, 2011 (revised), California Environmental Quality Act Air Quality Guidelines. <br />sb Bay Area Air Quality Management District, 2011 (revised), California Environmental Quality Act Air Quality Guidelines. <br />P L A C E W 0 R K S 4.2-21 <br />
