Therefore, the annual tonnage of emissions is multiplied by 2,000 pounds per ton to identify total pounds of emissions and divided by 365 days per year to identify average daily emissions. Source: CalEEMod Output (see Appendix B). Values above which represent less than 0.005 are automatically rounded down and shown as <0.01. As shown in Table 5, the proposed project would not exceed the BAAQMD’s thresholds of significance during operation, indicating that ongoing project operations would not be considered to have the potential to generate a significant quantity of air pollutants. Therefore, long-term operational impacts associated with criteria pollutant emissions generated by the proposed project would be less than significant. Operational Carbon Monoxide Hotspot The CO emissions from traffic generated by the proposed project are not estimated to be a concern at the local level. However, congested intersections can result in the potential for high, localized concentrations of CO, known as a CO hotspot. The BAAQMD recommends a screening analysis to determine whether a project has the potential to contribute to a CO hotspot. The screening criteria identify when site-specific CO dispersion modeling is necessary. The proposed project would result in a less than significant impact to air quality for local CO if all the following screening criteria are met: • The project is consistent with an applicable Congestion Management Program (CMP) established by the County Congestion Management Agency (CMA) for designated roads or highways, regional transportation plan, and local CMA plans; and • The project traffic would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour; and • The project traffic would not increase traffic volumes at affected intersections to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, bridge underpass, natural or urban street canyon, below-grade roadway). The Local Traffic Analysis prepared for the proposed project analyzes the proposed project in comparison to the General Plan Level of Service (LOS) D Standard and demonstrates consistency with the residential development studies in the 2012 Housing Element. As a result, the proposed project would be consistent with local and associated plans.
