Statement of Facts and Findings emissions of greenhouse gases, Thus, these GHGs related impacts would be less than significant, and no mitigation measures are necessary. Hazards and Hazardous Materials A. Facts The 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. Construction activities would be implemented in compliance with the existing South Coast Air Quality Management District (SCAQMD), CaVOSHA, and the California Health and Safety Code requirements. These requirements were developed to protect human health and the environment from the hazards. Hence, compliance applicable regulations would reduce impacts related to the release of hazardous materials into the environment to a less- than — significant level. In addition, operation of the project would utilize common types of hazardous materials; normal routine use of these products pursuant to existing regulations would not result in a significant hazard to the public or to the environment. Impacts would be less than significant. 2. The project would not be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment. As described above, a perchlorate- impacted groundwater plume extends under the project site within a well - defined, relatively narrow area within the western portion of the site. Excavation activities for the project would not extend to the depth of the plume; thus, project activities would not encounter hazardous contamination that could present a potential health or safety risk, and impacts related to the existing groundwater contamination wound be less than significant. In addition, onsite soils have not been identified to contain any contaminants above the California Human Health Screening Levels developed by the Califori- a Environmental Protection Agency. Should contaminants be identified on site during construction, adherence to applicable regulatory DTSC, County of Orange Environmental Health Division, and the Orange County Fire Authority guidelines would ensure that impacts are less than significant. I The project would not create a significant safety hazard related to John Wayne Airport (JWA) operations to the people residing or worldng on the project site. JWA is located approximately 1.8 miles southwest of the project site; however, is not within JWA's Airport Safety Zone, the Ali-port Impact Zone, Runway Protection Zone, Obstruction of Imaginary Surfaces area, or the 65 CNEL Noise Contours. In addition, the proj ect would not result in 1k2zards related to excessive glare, light, steam, smoke, dust, or electronic interference. Thus, the project would not introduce a safety hazard associated with airport operations for people residing, working, and visiting the project site. Project - related impacts associated with JWA operations would be less than significant. 4. The project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Direct access to the project site is provided from East Dyer Road and Red Hill Avenue, which are adjacent to the project site. Construction activities would not restrict access of emergency vehicles to the project site or adjacent areas from the The Heritage Mixed Use protect 12 J� USA 1140730 statement of Fscts and Findings September 2015
