7.B. - Page 111 Redwood City Chapter 4.Environmental Impact Analysis expected that the proposed modifications would be operated in compliance with all applicable federal,state,and local regulations.Additionally,any potential construction-related hazardous releases or emissions would be from commonly used materials such as fossil fuels,solvents,and paints and would not include substances listed in Title 40 of the Code of Federal Regulations, Part 355 Appendix A,"Extremely Hazardous Substances and Their Threshold Planning Quantities."Any spills would be localized and immediately contained and cleaned up in compliance with applicable rules and regulations.Therefore,construction of the proposed modifications would not significantly affect land uses within 0.25-mile,including Hoover Elementary School. New impacts would be less than significant. d. Be located on a site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and,as a result, would create a significant hazard to the public or the environment? Less-than-Significant New Impact.A database review of recorded and hazardous material storage sites within 1 mile of the project site was conducted for the 2007 FEIR(page 4.11-2).According to the review,several sites were located within one mile of the project site.The original Costco Wholesale building(prior to relocation)was listed as a small quantity generator of hazardous waste due to the operation of an onsite film processing area.Additionally,during the time period from approximately 1942 to 1982,S&W operated a fruit cannery facility on the northwestern portion of the site (northwest of the Charter Street alignment) and on the property currently occupied by Orchard Supply Hardware.Although the historical industrial use of the site had the potential to release petroleum hydrocarbons into onsite soils,any releases would have been small and would likely have been disturbed when the original Costco warehouse and parking lot were constructed. Based on a recent review of hazardous materials sites,the Costco building is no longer listed as a small quantity generator of hazardous waste. Because the project site is not located on a site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5,the proposed modifications would not create a significant hazard to the public or the environment and new impacts would be less than significant. e. For a project within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, result in a safety hazard for people residing or working in the project area? Less-than-Significant New Impact.The project site is located approximately 3 miles southeast of the San Carlos Airport.The San Carlos Airport is a general aviation airport that is home to approximately 500 aircraft and has approximately 130,000 aircraft operations per year(San Mateo County 2008).The project site is not located within the airport's approach zone or within any of the airport noise contours that are identified in the San Mateo County Comprehensive Land Use Plan (San Mateo County 1996).Therefore,the proposed modifications would not be located within an airport land use plan,and is not anticipated to result in a new significant safety hazard for people residing or working in the project area. f. For a project within the vicinity of a private airstrip, result in a safety hazard for people residing or working in the project area? No New Impact.The project site is not located in the vicinity of a private airstrip.As described in the discussion in Section 4.10.e,the closest airport is the San Carlos Airport,a municipal (public) facility.As described above,the proposed modifications would not result in a safety hazard related Addendum No.2 to the Environmental Impact Report for 4-66 September 2012 the Redwood City Costco Wholesale Project ICF 00154.12
