FIRS1'CARBON Proposal S O LU T I O N S ' emissions. However, it should be noted that BAAQMD's construction thresholds only apply to exhaust- related PM10 and PM25.The average daily construction-related criteria pollutant and ozone precursor (ROG and NOX) emissions estimates will be compared with BAAQMD's thresholds of significance. Following construction of the proposed project, long-term operational emissions would be generated by the proposed resident's area-, energy-, and mobile-source emissions. FCS will rely on vehicle trip generation data from the traffic study to model mobile source emissions,while area-and energy-source emissions will be modeled using CaIEEMod. Long-term daily operational emissions will also be compared with BAAQMD's thresholds of significance to determine impacts. FCS will prepare a Request for Information (RFI)detailing all project construction and operational parameters required to perform the modeling. In the case that project-specific information is not available at the time of the analysis, FCS will work with the project applicant to develop reasonable assumptions, or use CaIEEMod defaults. It should be noted that default assumptions typically result in conservative results in order to avoid underestimating emissions when project-specific information is unknown. Following finalization of model assumptions through the RFI, major changes to the project features, design,schedule or other parameters)that precipitate revisions to the emissions modeling may warrant a budget augment. Greenhouse gas emissions associated with construction and operation of the project will also be estimated using CaIEEMod. For the GHG analysis,CaIEEMod estimates GHG emissions in units of metric tons of carbon dioxide equivalent(MT CO2e),which accounts for the global warming potential of GHGs such as carbon dioxide, methane, and nitrous oxide. FCS will use BAAQMD or other applicable thresholds of significance to evaluate the project's construction and operational GHG emissions. In addition, FCS will analyze the project's consistency with the City of Pleasanton's Climate Action Plan as required by CEQA.The analysis will also address the recent State Supreme Court ruling on the Newhall Ranch project.Changes to the project that occur after completing the modeling analysis that require re- modeling will be considered additional work that is not covered by this scope of work. Assess Odor Exposure The analysis will assess odor exposure to nearby residents.The discussion will compare the project to the screening criteria and buffer distances prescribed by BAAQMD and the California Air Resources Board (ARB). FCS will provide a qualitative analysis of the project's potential to generate an odor impact. Based on the project land uses (i.e., residential), it is not anticipated that the project would result in an odor impact. Assess Carbon Monoxide Hotspot Impacts FCS will use the BAAQMD's screening criteria for carbon monoxide(CO) hotspots,which is anticipated to be sufficient to dismiss any potential impacts. However, in the case that potential CO hotspots are identified, FCS will use dispersion modeling to quantify impacts according to BAAQMD guidance under a revised scope of work and budget. Quantitative CO Hotspot modeling would be considered additional services, if required. NORTH AMERICA I EUROPE I AFRICA I AUSTRALIA I ASIA 6 FIRSTCARBONSOLUTIONS.COM
