4 <br /> <br /> <br />As you can see in the excerpt above, the total number of daily trips estimated for the proposed Project <br />is 1,420. However, review of the Project’s CalEEMod output files demonstrates that the Saturday and <br />Sunday trip rates are underestimated (see excerpt below) (Appendix C, pp. 155, 182, 207). <br /> <br />As you can see in the excerpt above, the total numbers of daily trips that were calculated for Saturday <br />and Sunday were underestimated by approximately 59 and 320 trips, respectively. This is inconsistent <br />with the information provided in the Traffic Impact Analysis Report, and thus, the Saturday and Sunday <br />trip rates were underestimated within the model. As a result, the Project’s operational emissions are <br />underestimated and should not be relied upon to determine Project significance. Diesel Particulate Matter Health Risk Emissions Inadequately Evaluated <br />The Addendum concludes that the proposed Project would have a less than significant impact on the <br />health of sensitive receptors near the Project site without conducting a quantitative health risk <br />assessment (HRA) for construction and operation (p. 3.2-2). The Addendum fails to conduct a quantified <br />HRA and instead relies upon a Localized Significance Threshold (LST) analysis, which found that Project <br />emissions would not exceed the SCAQMD LSTs. Based on the LST analysis and qualitative assertions, the <br />Addendum concludes that the Project would have a less than significant impact on nearby sensitive <br />receptors. Regarding construction-related health risks, the Addendum states, <br />“Table 3.2-2 shows the on-site construction emissions and compares them to the Local <br />Significance Thresholds (LSTs) established by SCAQMD to represent the maximum emissions
