South Coast Technology Center Project CEQA Exemption 15183 transport, or disposal would be required to comply with existing regulations of the USEPA, US Department of Transportation, CalRecycle, and other agencies, consistent with the industrial uses analyzed in the GPU PEIR. Therefore, operation of the proposed Project would result in less than significant impacts related to the use, storage, transport, and disposal of hazardous wastes, as well as related to the accidental release of hazardous materials. The Project Site is not listed in the State Water Resources Control Board (SWRCB) GeoTracker system which includes leaking underground fuel tank sites and spills, leaks, investigations, and cleanups sites; or the DTSC EnviroStor Data Management System which includes Cortese sites; or the USEPA's database of regulated facilities.25, 26 As such, consistent with the GPU PEIR, impacts related to hazardous materials sites would be less than significant. According to Figure 5.8-5, John Wayne Airport Safety Compatibility Zones, and Figure 5.8-6, Height Restrictions per Federal Air Regulations Part 77, of the GPU PEIR, the Project Site is located outside of the John Wayne Airport's safety compatibility zone and height restriction areas. As such, the proposed Project would not result in a safety hazard or excessive noise for people residing and working in the Project area. No impact would occur. Construction equipment and materials staging would occur within the Project Site. During construction, vehicular access would be provided via existing access points along Lake Center Drive and South Susan Street. Temporary partial lane closures of Susan Street and Lake Center Drive would be required to resurface the streets; during the resurfacing, access would be maintained. Full lane closures are not anticipated for the proposed Project. Operation of the proposed Project would not result in population growth or changes to the existing circulation system. All driveways would provide adequate space for emergency vehicle access. As such, the proposed Project would not interfere with operations of the City's Emergency Operations Center and would not interfere with operations of emergency response agencies or with coordination and cooperation between such agencies; thus, consistent with the GPU PEIR, impacts to emergency response planning would be less than significant. The City of Santa Ana is not in a designated fire hazard zone. As such, consistent with the GPU PEIR, no impact related to the risk of wildland fires would occur. Based on the above, the Project would not result in new or substantially more severe impacts compared to the determinations of the GPU PEIR, which concluded that impacts related to the transport, use, disposal, and release of hazardous materials; hazardous materials sites; sites located within the vicinity of an airport or in an airport land use plan; and impairment of an emergency response or evacuation plan would be less than significant; and that no impacts would occur related to the risk of wildland fires. Therefore, no new project -specific mitigation measures are required. 25 California State Water Resources Control Board, GeoTracker, https://geotracker.waterboards.ca.gov/map/, accessed April 25, 2024. 26 California Department of Toxic Substances Control, Envirostor, https://www.envirostor.dtsc.ca.gov/public/, accessed April 25, 2024.
