Community Plan Exemption Checklist <br />City of Santa Ana Gary Avenue Business Park Project <br />Operation <br />Operational activities associated with the Project would result in emissions of CO, VOCs, NOx, SOx, PMio, <br />and PM2.5. Operational related emissions are expected from the following primary sources: area source <br />emissions, energy source emissions, mobile source emissions, and on -site equipment emissions. Implementation <br />of the proposed Project would result in long-term regional emissions of criteria air pollutants and ozone <br />precursors associated with area sources, such as natural gas consumption, landscaping, applications of <br />architectural coatings, and consumer products. Operational vehicular emissions would generate a majority <br />of the emissions from implementation of the Project. <br />Operational emissions associated with the proposed Project were modeled using CaIEEMod and are <br />presented in Table AQ-3. As shown, the proposed Project would result in long-term regional emissions of <br />criteria pollutants, however, these emissions would be below the SCAQMD's applicable thresholds. Therefore, <br />the Project's operational emissions would not exceed the NAAQS and CAAQS, would not result in a <br />cumulatively considerable net increase of any criteria pollutant, and impacts would be less than significant. <br />Table AQ-3: Proposed Project Operational Emissions <br />Source <br />Reactive <br />Organic <br />Gases <br />(ROG) <br />Nitrogen <br />Oxide <br />(NOx) <br />Carbon <br />Monoxide <br />(CO) <br />Sulfur <br />Dioxide <br />(S02) <br />Coarse <br />Particulate <br />titter <br />) <br />Fine <br />Particulate <br />Matter <br />(M2.5) <br />Summer Emissions <br />Area Source Emissions <br />2.11 <br />0.00 <br />0.02 <br />0.00 <br />0.00 <br />0.00 <br />Energy Emissions <br />0.01 <br />0.10 <br />0.08 <br />0.00 <br />0.00 <br />0.00 <br />Mobile Emissions <br />0.52 <br />6.65 <br />6.34 <br />0.04 <br />2.80 <br />0.81 <br />Off -road Emissions <br />1.97 <br />16.47 <br />15.95 <br />0.04 <br />0.85 <br />0.78 <br />Total Emissions <br />4.61 <br />23.22 <br />22.39 <br />0.08 <br />3.65 <br />1.59 <br />SCAQMD Threshold <br />55 <br />55 <br />550 <br />150 <br />55 <br />750 <br />Exceeds Threshold? <br />No <br />No <br />No <br />No <br />No <br />No <br />Winter Emissions <br />Area Source Emissions <br />2.10 <br />0.00 <br />0.02 <br />0.00 <br />0.00 <br />0.00 <br />Energy Emissions <br />0.01 <br />0.10 <br />0.08 <br />0.00 <br />0.00 <br />0.00 <br />Mobile Emissions <br />0.53 <br />6.92 <br />6.08 <br />0.04 <br />2.80 <br />0.81 <br />Off -road Emissions <br />1.97 <br />16.47 <br />15.95 <br />0.04 <br />0.85 <br />0.78 <br />Total Emissions <br />4.61 <br />23.49 <br />22.13 <br />0.08 <br />3.65 <br />1.59 <br />SCAQMD Threshold <br />55 <br />55 <br />550 <br />750 <br />55 <br />750 <br />Exceeds Threshold? <br />No <br />No <br />No <br />No <br />No <br />No <br />Source: Air Quality Assessment (Appendix A) <br />b) Expose sensitive receptors to substantial pollutant concentrations? <br />No New Impact. The daily construction emissions generated onsite by the proposed Project are evaluated <br />against SCAQMD's Localized Significance Thresholds (LSTs) to determine whether the emissions would cause <br />or contribute to adverse localized air quality impacts. Receptor locations are off -site locations where <br />individuals may be exposed to emissions from Project activities. <br />Some people are especially sensitive to air pollution and are given special consideration when evaluating <br />air quality impacts from projects. These groups of people include children, the elderly, individuals with pre- <br />existing respiratory or cardiovascular illness, and athletes and others who engage in frequent exercise. <br />Structures that house these persons or places where they gather to exercise are defined as "sensitive <br />38 <br />
