Source: Dudek Air Quality Technical Report (March 2010). 4.5.2 Thresholds of Significance Appendix G of the CEQA guidelines defines a potentially significant air quality impact as one that would: mm Conflict with or obstruct the implementation of the applicable air quality plan; ~~~u Violate any air quality standard or contribute substantially to an existing or projected air quality violation; ~~~u Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for 03 precursors); ~~~u Expose sensitive receptors to substantial pollutant concentrations; or ~~~u Create objectionable odors affecting a substantial number of people. Project Pollutants The City of Chula Vista evaluates project emissions based on the quantitative emission thresholds established by the SCAQMD in their CEQA Air Quality Handbook (SCAQMD 1993). The SCAQMD sets forth quantitative emission significance thresholds below which a project would not have a significant impact on ambient air quality. Project-related air quality impacts estimated in this environmental analysis would be considered significant, if any of the applicable significance thresholds presented in Table 4.5-4, SCAQMD AirQuaky Sign~cance Thresholds, are exceeded.

The Project Site is located in San Diego County, within the SDAB, which is governed by the SDAPCD. The SDAPCD regulates air quality over most types of stationary emission sources through its permit authority, as well as planning and enforcement activities. SDAPCD's air quality plan describes air pollution control strategies that are to be implemented by region's classified as nonattainment areas. The purpose of the plan and strategies is to eventually bring the area into compliance with Federal and State requirements, classifying it as an attainment area. The proposed project is not anticipated to violate, or increase violation of, air quality standards or exceed emission thresholds, and is thus would not conflict with the SDAPCD's air quality plan. The project would be short term and, following the construction phase, would not result in any emissions. Impacts would be less than significant Construction Emissions Construction of the proposed project would result in a temporary addition of pollutants to the SDAB, caused by soil disturbance, dust emissions, and combustion pollutants from on-site construction equipment and off-site trucks hauling construction materials. Construction emissions would vary daily, depending on the level of activity, the specific type of operation, and, for dust, the current weather conditions. Therefore, such emission levels can only be estimated. Grading and site preparation activities would primarily cause fugitive dust emissions, while use of construction equipment and motor vehicles would result in NOx and CO emissions. Emissions from the construction phase of the project were estimated through the use of emission factors from the URBEMIS 2007, Version 9.2.4, land use and air emissions model (Rimpo and Associates 2007. For the purposes of modeling, it was assumed that the proposed project would commence in December 2039 (model does not go beyond 2040). The duration of construction in each stage of the project is as listed below: ~~~u equipment removal (three weeks) ~~~u rough grading (four weeks) ~~~u revegetation (four weeks) mm monitoring and maintenance (intermittent over a three to five year period). Emissions associated with the monitoring and maintenance stage were not modeled due to the fact that activities would only occur on a seasonal basis and would not require a significant amount of equipment For the analysis, it was assumed that heavy construction equipment would be operating on-site for approximately eight hours per day, five days per week (22 days per month), during project construction. Additional details of the construction schedule are included in Appendix E (the AirQuak'ty Tecbrrical Bej~ort). The equipment mix anticipated for construction activity was based on typical construction practices. The proposed project is subject to SDAPCD Rule 52 -Particulate Matter. This requires the project to take reasonable steps to limit emissions of fugitive dust beyond the property line. Compliance with Rule 52 would limit any PMio that may be generated during reclamation activities. When dust control and mitigation measures were factored into the calculations (it was assumed that the active sites would be watered at least three times daily), the result was an approximately 61 percent reduction of particulate matter.

Sensitive Receptors \ir qu.tlitt' problems arise when the rate of polhiuu7t emissions eiceeds the rate of dispersion. Ceru~in ku7d uses arc c~~nsidcrcd more sensiti~c to chanties in air quality than others, depcndinti ~~n the tnhabitinti popukttion and acut~ities intoh~ed. People most lihela to be affected ba .sir pollution, as identified ba the GARB, include children, the elderla, athletes, and people with cardiotascular and chronic respirttora diseases. (:~~nccntrtti~~ns of pollutants in c~ccss of the dctincd thresholds arc of increased c~~nccrn for areas (deemed sensiti~z reccptorsj ~ here these tiroups mat' be located, ~ hich include residcnccs, schools, plaatirounds, chiklrtre ccntcrs, athletic facilities, kmti term hetlth care facilities, rehabilitation ccntcrs, coat.tlesecnt ccntcrs, u7d ruiremcnt homes. In the project area currcntla, reduced tisibilin', eae irritation, and adt-erse hetlth nnpacts arc the most serious evsunti .ur qu.tlita hazards. 1'hcrc arc currcntla no scnstti~c receptors in the ~icinita of the Project Sitc. 1'hc nearest residcnccs arc located approiimatela 4,00 feet or more to the southwest of the vte.
