City of Santa Ana Environmental Checklist project site, but has been appropriately removed and the City's Fire Department provided a closure letter in 2005 to the site's previous owner. As such, the project site does not contain any hazardous materials that could result in the release of materials into the environment. As discussed in VIII.a, project construction and operation activities would involve a limited use of hazardous materials. Equipment that would be used in construction of the proposed project has the potential to release oils, greases, solvents, and other finishing materials through accidental spills. However, the consequences of construction- related spills are not substantial because the volume of hazardous materials held within any single piece of construction equipment is limited. Construction - related spills of hazardous materials are not uncommon, but the enforcement of construction and demolition standards, including BMPs by appropriate local and state agencies, would minimize the potential for an accidental release of petroleum products and /or hazardous materials or explosions during construction. Federal, state, and local regulations would be followed by the construction contractor to reduce the effects of potential hazardous materials spills. Likewise, operation of the proposed project would use and store a limited amount hazardous materials including solvents, cleaning agents, paints, and pesticides. Large volumes of these hazardous materials would not be stored on site. Any spill or release of the hazardous materials stored or routinely used in operation of the project is not anticipated to have the volume to result in a significant hazard to residents or workers in the vicinity of the project. Farther, because the project would comply with federal, state, and local hazardous waste regulations, the proposed project would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment. c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one - quarter mile of an existing or proposed school? Less - than - Significant Impact. The proposed project involves the construction and operation of a residential school and is also located within 0.25 mile of other school sites. As described in VIII.b, construction and operation of the proposed project would involve the use of small amounts of hazardous materials subject to federal, state, and local regulations. No element of the proposed project would involve acutely hazardous materials, substances, or wastes. In addition, emissions from construction and operation of the project were evaluated in the air quality analysis presented in Section iil. It was determined that after implementation of mitigation, the maximum emissions from the project would not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards. Therefore, implementation of the proposed project would not emit hazardous emissions or handle hazardous materials within 0.25 mile of a school. d. Be located on a site that is included on a list of hazardous materials sites that complied pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? No Impact. A Phase i site assessment was prepared in 2011, which included a federal, state, and local database search and determined that the proposed project site is not included on a list of hazardous material sites (Athanor 2011a). In addition, soil and groundwater investigations were completed in June 2011 that tested for pesticides, nitrates, petroleum hydrocarbons, toxic heavy metals, mercury, VOCs, and PCBs. The testing determined that the only compound to exceed its The Academy Charter High School 3 5� June 2012 Initial Study /Mitigated Negative Declaration (CF 00924.11 31 B -127
