SANTA ANA REZONE PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION respiratory problems. Human studies on the carcinogenicity of DPM demonstrate an increased risk of lung cancer, although the increased risk cannot be clearly attributed to diesel exhaust exposure. Construction and operation of the proposed project would be subject to applicable SCAQMD rules and requirements. The SCAQMD CEQAAir Quality Significance Thresholds were developed to assist local jurisdictions and lead agencies in complying with the requirements of CEQA regarding potentially adverse impacts to air quality.'$ Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? Less than significant impact. The 2022 Air Quality Management Plan (AQMP) is the current applicable regional Air Quality Plan (AQP) of SCAQMD. The primary goals of the AQP are to protect public health and protect the climate. The 2022 AQMP includes the integrated strategies and measures needed to meet the National Ambient Air Quality Standards (NAAQS). Furthermore, the 2022 AQMP demonstrates attainment of the 1-hour and 8-hour ozone NAAQS as well as the latest 24-hour and annual PM2.5 standards.19 Because the proposed project does not involve population or employment growth, determining consistency with the 2022 AQMP involves assessing whether applicable control measures contained in the 2022 AQMP are implemented and whether implementation of the proposed project would disrupt or hinder implementation of AQP control measures. All projects within SCAQMD's jurisdiction are required to implement Rule 403 as the Best Available Control Measures (BACMs) during construction activities. The proposed project would implement all BACMs consistent with Rule 403 during construction activities and would be consistent with the assumptions in the AQMP. Furthermore, the proposed project is a typical construction design for parking lots and would not include any special features that would disrupt or hinder implementation of the AQMP control measures. In addition, if a project's emissions do not exceed the SCAQMD regional thresholds for VOC, NOx, CO, SOx, PM1o, or PM2.5, it follows that the project's emissions would not exceed the allowable limit for each project in order for the region to attain and maintain ambient air quality standards, which is the primary goal of air quality plans. As shown in Impact 2.3(b), the proposed project would not exceed the SCAQMD's regional thresholds of significance during construction and operation. Therefore, the proposed project would not conflict with or obstruct implementation of the 2022 AQMP. This impact would be less than significant. 8 South Coast Air Quality Management District (SCAQMD). 2023. Air Quality Significance Thresholds.
