City of Santa Ana Environmental Checklist Regional Emissions Thresholds Localized Emissions Thresholds] Pollutant Construction Operation Construction Operation Sulfur Oxides (SOx) ISO ISO N/A N/A Carbon Monoxide (CO) 550 550 715 715 Lead (Pb)1 3 3 N/A N/A Notes: I The proposed project would have no lead emissions sources during the construction or operations period. As such, lead emissions are not evaluated in this report. 2Localized thresholds derived from SCAQMD Localized Significance Threshold Tables and are based on the project location (Source Receptor Area [SRA)17, the Central Orange County), project area disturbed in any given day (2-acres), and the distance to the nearest sensitive receptor (25 meters), Source: SCAQMD CEQAAir Quality Handbook, 1993 (As amended at liftp://www.aqllid.gov/ceqa/ handbook/signthres.pdf); SCAQMD Localized Significance Threshold Methodology for•CEQA Evaluations; and Particulate Matter (PM) 2.5 Significance Thresholds and Calculation Methodology. Impact Analysis Would the project: a. Conflict with or obstruct implementation of the applicable air quality plan? No lmpacL SCAQMD is required, pursuant to the federal CAA, to reduce emissions of criteria pollutants for which the Basin is in nonattainment (Le, 03, PMio, and PM2.s). The project would be subject to SCAQMD's AQMP, which contains a comprehensive list of pollution control strategies directed at reducing emissions and achieving ambient all, quality standards. These strategies are developed, in part, based on regional population, housing, and employment projections prepared by SCAG. The project site is located within the City of Santa Ana and is currently zoned as RI Single Family Residential. The project proponent is seeking a Conditional Use Permit that would allow religious uses on a parcel zoned R1. Given that the project would convert two low density residential lots (RI) to a community religious use, there would be no material effect on regional population, housing, and employment projections that form the basis of AQMP growth assumptions. As such, the project would not conflict with the AQMP, which is wafted to bring the Basin into attainment for all criteria pollutants. Additionally, all construction activities would be in compliance with AQMP regulatory measures, including SCAQMD rules pertaining to fugitive dust (Rules 403, 404, and 405), visibility of emissions (Rule 401), nuisance activities (Rule 402), and limiting VOC content in both asphalt and architectural coatings (Rules 1108 and 1113). Finally, as discussed below under IlLb, project operational emissions would fall below the SCAQMD thresholds of significance. Accordingly, the proposed project would be consistent with the projections in the AQMP. No impact would occur with respect to AQMP implementation and no mitigation measures are required.
