CITY OF SAN LEANDRO SAN LEANDRO SHORELINE DEVELOPMENT PROJECT EIR EXHIBIT A: WORK SCOPE AND COSTS pollutant emissions generated by the project will be compared to BAAQMD's average daily and annual criteria air pollutant thresholds. The operational phase analysis will also evaluate consistency with BAAQMD's 2010 Bay Area Clean Air Plan, placement of sensitive land uses proximate to existing odors, and carbon monoxide hotspots. The Planning Center I DC&E anticipates that the project would not generate enough traffic volumes to warrant a detailed carbon monoxide hotspot analysis; therefore, a detailed analysis compared to BAAQMD's carbon monoxide thresholds is not necessary and impacts would be handled qualitatively. Likewise,proposed land uses are not likely to generate substantial odors (e.g. restaurants with five or more employees are required to comply with BAAQMD Regulation 7, Odorous Substances, which prohibits the generation of nuisance odors)or place new sensitive receptors proximate to existing sources of odors;therefore,this would also be handled qualitatively. Cumulative air quality impacts will also be described. b. On-Site Operational Health Risk A quantitative health risk assessment will be conducted in accordance with the BAAQMD's guidance document Recommended Methods for Screening and Modeling Local Risks and Hazards and the BAAQMD's recently adopted CEQA Guidelines. Dispersion modeling will be performed using a BAAQMD-accepted computer-based model (e.g. ISCST3, AERMOD, or CAL3QHCR) to determine ground-level concentrations of hazardous air pollutants at the project site. Cancer and toxicity data published by Cal-EPA will be used to estimate long-term health risks for on-site sensitive receptors. If the health risk assessment finds that sensitive receptor exposure to PM2,5 and TACs is significant, potential mitigation measures would be recommended. c. Regional Construction Emissions A full construction emissions analysis will be conducted for the proposed project using a BAAQMD approved model (e.g. CalEEMod). Construction emissions generated by the project will be estimated based on the construction phasing,the construction schedule for each phase, and the construction equipment use per phase provided by the Master Developer and/or City. Modeling will include three development phases,as identified in the RFP. Because it is unlikely that a detailed construction equipment list is available for all phases at this time, construction emissions may be based on CaIEEMod defaults. The construction equipment defaults in the CaIEEMod program are based on surveys conducted of construction sites. We will work with the Master Developer and/or City to develop the construction assumptions used in the model. Criteria air pollutant emissions from THE PLANNING CENTER I DC&E 13 MAY 1,2013
