(g) Hazards and Hazardous Materials: Construction and operations under the GPU would involve the transport, use, and/or disposal of hazardous materials; however, compliance with existing regulations would ensure that construction workers and the general public are not exposed to any risks related to hazardous materials during demolition and construction. Furthermore, strict adherence to all emergency response plan requirements set by the Orange County Fire Authority would be required throughout the duration of project construction. GPU buildout is expected to result in some increase in the number of hazardous waste generators; however, hazardous wastes would be stored, transported, and disposed of in conformance with existing regulations of the EPA, US Department of Transportation, CalRecycle, and other agencies. Use, storage, transport, and disposal of hazardous materials in conformance with regulations would reduce both the likelihood of an accidental release and the potential consequences in the event of an accidental release. The plan area includes 555 sites on a list of hazardous materials compiled pursuant to Government Code Section 65962.5 that could create a significant hazard to the public or the environment. Any development, redevelopment, or reuse on or next to any of these sites would require environmental site assessment by a qualified environmental professional to ensure that the project would not disturb hazardous materials on any of the hazardous materials sites or plumes of hazardous materials diffusing from one of the hazardous materials sites, and that any proposed development, redevelopment, or reuse would not create a substantial hazard to the public or the environment. Santa Ana is in the vicinity of an airport or within the jurisdiction of an airport land use plan. Projects approved under the proposed GPU would be required to comply with FAA airspace protection regulations using the AELUP consistency determination process. The buildout of the GPU would not result in substantial changes to the circulation patterns or emergency access routes, and would not block or otherwise interfere with use of evacuation routes. Buildout would not interfere with operation 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. Santa Ana is not in a designated fire hazard zone, and implementation of the GPU will not expose structures and/or residences to wildland fire danger. (h) Hydrology and Water Quality: Projects pursuant to the GPU would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality. Development pursuant to the GPU would increase the demand on groundwater use but would not impede sustainable groundwater management of the basin. Development pursuant to the GPU would increase the amount of pervious surfaces in the plan area, but could substantially increase the rate or amount of surface runoff in some focus areas in a manner which would result in flooding off -site or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems. In flood hazard, tsunami, or seiche zones, development pursuant to the GPU would not risk release of pollutants due to project inundation or impede or redirect flood flows.
