Community Plan Exemption Checklist City of Santa Ana Gary Avenue Business Park Project The GPU EIR also determined that because existing sensitive receptors may be close to project -related construction activities and large emitters of on -site operation -related criteria air pollutant emissions, construction and operation emissions generated by individual development projects have the potential to exceed South Coast AQMD's Local Significance Thresholds (LSTs). The EIR describes that Mitigation Measures AQ-1 and AQ-2 would reduce the regional construction and operation emissions associated with buildout of the GPU and therefore also result in a reduction of localized construction- and operation -related criteria air pollutant emissions, to the extent feasible. However, even with the implementation of these mitigation measures, impacts would remain significant and unavoidable. The GP EIR also describes that buildout of the GPU could expose sensitive receptors to substantial concentrations of toxic air contaminants JAC). Mitigation Measure AQ-3 was included to ensure mobile sources of TACs not covered under South Coast AQMD permits are considered during subsequent, project - level environmental review by the City of Santa Ana. The EIR describes that individual development projects would be required to meet the incremental risk thresholds established by South Coast AQMD, with implementation of Mitigation Measure AQ-3, and TACs would be less than significant a project level but would result in a cumulative contribution to health risk that is significant and unavoidable. The GPU EIR determined that the GPU Industrial and Industrial Flex land uses are not anticipated to produce odors, and Mitigation Measure AQ-4 would ensure that odor impacts are minimized, and facilities would comply with South Coast AQMD Rule 402. Impacts Associated with the Proposed Project a) Conflict with or obstruct implementation of the applicable air quality plan? No New Impact. The Project site is located in the South Coast Air Basin and is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD and the SCAG are responsible for preparing the Air Quality Management Plan (AQMP), which addresses federal and state Clean Air Act (CAA) requirements. The AQMP details goals, policies, and programs for improving air quality in the Basin. Criteria for determining consistency with the AQMP are defined in Chapter 12, Sections 12.2 and 12.3 of the SCAQMD's CEQA Air Quality Handbook (1993). A project is considered consistent with the AQMP if it would not result in or cause California Ambient Air Quality Standards (CAAQS) or National Ambient Air Quality Standards (NAAQS) violations. In addition, the SCAQMD considers a project consistent with the AQMP if the project would not result in an increase in the frequency or severity of existing air quality violations or cause a new violation. Furthermore, The South Coast Air Basin (SCAB) is in a non -attainment status for federal ozone standards, federal carbon monoxide standards, and state and federal particulate matter standards. Any development in the SCAB, including the proposed Project, could cumulatively contribute to these pollutant violations. Should construction or operation of the proposed Project exceed these thresholds a significant impact could occur; however, if estimated emissions are less than the thresholds, impacts would be considered less than significant. The Project proposes to demolish the existing three buildings, which total 103,031 square feet and to construct a new approximately 91,500 square foot industrial building that would accommodate two tenants with 5 dock doors for each tenant. Of the 91,500 square feet, 81,500 square feet would be used for warehouse facility and 10,000 square feet would be used for office space. The GPU and GPU EIR assumed that the Project site would be developed with the FLEX-3 designation that allows for clean industrial uses. The Project is consistent with the development assumptions for Project site in the GPU EIR, and the land use designations of the GPU are consistent with the 2016 AQMP. As detailed in Response b), the CalEEMod modeling prepared for the proposed Project determined that construction and operation of the Project would not exceed SCAQMD thresholds, including the CAQQS and NAAQS. The proposed Project is therefore considered to be consistent with the current 2016 AQMP. Therefore, the Project would result in no new impacts related to conflict with implementation of an air quality plan. 36
