South Coast Technology Center Project CEQA Exemption 15183 manufacturing, and food manufacturing facilities would not be permitted. Therefore, the GPU PEIR concluded that odor impacts would be less than significant. 4.3.2 Project Analysis The following section evaluates potential short- and long-term air quality impacts that would result from the construction and operation of the proposed Project. The analysis is primarily based upon Attachment A, Air Quality Assessment, and Attachment B, Health Risk Assessment. The Air Quality Assessment and Health Risk Assessment were prepared to fulfill the requirements of GPU PEIR MM AQ-1, MM AQ-2, and MM AQ-3. CONSISTENCY WITH APPLICABLE AIR QUALITY PLAN On December 2, 2022, the SCAQMD Governing Board adopted the 2022 AQMP. The 2022 AQMP incorporates the latest scientific and technical information and planning assumptions, including the latest applicable growth assumptions, updated emission inventory methodologies for various source categories. Additionally, the 2022 AQMP utilized information and data from the South Coast Association of Governments (SCAG) and its 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). While SCAG has recently adopted Connect SoCal2024 (i.e., the 2024-2050 RTP/SCS), SCAQMD has not released an updated AQMP based off of the 2024-2050 RTP/SCS growth projections. As such, this consistency analysis is based off the 2022 AQMP and the RTP/SCS that was adopted at the time, the 2020-2045 RTP/SCS. According to the SCAQMD's CEQA Air Quality Handbook, projects must be analyzed for consistency with two main criteria, as discussed below. Criterion 1: With respect to the first criterion, SCAQMD methodologies require that an air quality analysis for a project include forecasts of project emissions in relation to contributing to air quality violations and delay of attainment. i) Would the project result in an increase in the frequency or severity of existing air quality violations? Since the consistency criteria identified under the first criterion pertain to pollutant concentrations, rather than to total regional emissions, an analysis of a project's pollutant emissions relative to localized pollutant concentrations associated with the California Ambient Air Quality Standards (CAAQS) and National Ambient Air Quality Standards (NAAQS) is used as the basis for evaluating project consistency. As detailed below under the Criteria Air Pollutants subsection, localized concentrations of CO, NOx, PM,o, and PM2.5 would be less than significant during Project construction and operations. Therefore, the proposed Project would not result in an increase in the frequency or severity of existing air quality violations. ii) Would the project cause or contribute to new air quality violations? As discussed below under the Criteria Air Pollutants subsection, the proposed Project would result in emissions that are below the SCAQMD thresholds. Therefore, the Project would not have the potential to cause or affect a violation of the ambient air quality standards. July 2024 Page 20
