a reduction in peak hour traffic, which would benefit arterials like Fourth Street between Tustin Avenue and Cabrillo Park Drive, which carry 23,828 vehicles during a weekday.' This would help reduce any potential that traffic volumes would generate CO exceedances of the ambient air quality standard.$ Finally, the Project would not result in any substantial emissions of TACs during the construction or operations phase. During the construction phase, the primary air quality impacts would be associated with the combustion of diesel fuels, which produce exhaust -related particulate matter that is considered a toxic air contaminant by CARB based on chronic exposure to these emissions.9 However, construction activities would not produce chronic, long-term exposure to diesel particulate matter. During long-term project operations, the Project does not include typical sources of acutely and chronically hazardous TACs such as industrial manufacturing processes and automotive repair facilities. As a result, the Project would not create substantial concentrations of TACs. In addition, the SCAQMD recommends that health risk assessments be conducted for substantial sources of diesel particulate emissions (e.g., truck stops and warehouse distribution facilities) and has provided guidance for analyzing mobile source diesel emissions.10 The Project would not generate a substantial number of truck trips. Based on the limited activity of TAC sources, the Project would not warrant the need for a health risk assessment associated with on -site activities. Thus, the Project's operational activities would not expose sensitive receptors to excessive emissions. Therefore, the Project would not result in any new or increased significant air quality impacts beyond those already identified in the Certified EIR. Odors The Project would not result in activities that create objectionable odors. The Project is a mixed - use development that would not include any activities typically associated with unpleasant odors and local nuisances (e.g., rendering facilities, dry cleaners). SCAQMD regulations that govern nuisances (i.e., Rule 402, Nuisances) would regulate any occasional odors associated with residences. Additionally, the Project would implement Mitigation Measure MM-OZ 4.2-1 from the City of Santa.

As discussed in the 2003 AQMP, the 1992 CO Plan included a CO hotspot analysis at four intersections in the peak A.M. and P.M. time periods, including Long Beach Boulevard and Imperial Highway (Lynwood), Wilshire Boulevard and Veteran Avenue (Westwood), Sunset Boulevard and Highland Avenue (Hollywood), and La Cienega Boulevard and Century Boulevard (Inglewood). The busiest intersection was Wilshire and Veteran, used by 100,000 vehicles per day. The 2003 AQMP estimated a 4.6 ppm one -hour concentration at this intersection, which meant that an exceedance (20 ppm) would not occur until daily traffic exceeded more than 400, 000 vehicles per day. 9 California Office of Environmental Health Hazard Assessment.
