Bicycle and Pedestrian Plan Initial Study Environmental Setting None of the planned open -space trails are located on sites that are currently used to store hazardous materials. The F_IR for the General Plan includes information regarding hazardous material and /or waste sites in Pleasanton from the Cal EPA website as of January 31, 2008. "Those sites are listed on Table 3.13 -1 of the EIR for the Proposed General Plan, published September, 2008. The City rechecked the Cal EPA website in June 2009 and found two additional sites on the Cortese List: Nuclepore Corporation at 2035 Commerce Circle and Tenneco Chemical, Inc. at 5555 Sunol Boulevard.' Some planned trails and bicycle routes are located less than 2 miles from the Livermore Airport, within the General Referral Area and the Height Referral Area Significance Criteria The impact questions above constitute the significance criteria for this environmental topic. Discussion of Checklist Items Less than -Si_ 'ficant Imo acts. The proposed Master Plan would not expose people to potential health hazards through the routine transport, use, storage or disposal of hazardous materials. Pedestrians, joggers, bicyclists, and equestrians would not be expected to use or transport any hazardous materials. During implementation of the proposed Master Plan, construction contractors would use some hazardous materials that could result in a possibility of hazardous materials upset. Hazards associated with those materials would be reduced to less than significant levels by compliance with State and federal transport, storage, and disposal requirements. No additional mitigation is warranted. Thus hazardous materials impacts would be less than significant. No toxic air contaminant would result from the proposed Master Plan, although minimal toxic air contaminants could occur due to construction of the Plan. Given the relatively small amount of toxic air contaminants that could result, this impact would he less than significant. Even if some of the proposed bicycle routes, sidewalks, or trails were to traverse a contaminated site, any development, including excavation, of such a site would be required by existing regulations to mitigate the impacts. The City has adopted an Emergency Operations Plan to provide for the safety of the community in the event of a major emergency such as an earthquake, flood, fire, nuclear accident, civil disturbance, or hazardous materials spill. The Emergency Operations Plan provides the basis for direction and control of emergency operations and contains task assignments for City personnel under emergency conditions.` In addition, future development resulting from the proposed Master Plan would be subject to the City's Emergency Operations Plan. Some of the proposed paths and trails are located close to or within wildlands subject to wildands fires. These areas would largely be used for recreational purposes and would be expected to bring few additional people into the hazardous areas. The additional trails and pathways would give residents additional evacuation routes in the event of fire or other natural disaster. Given the relatively minor increase in population along these trails, this would therefore be considered less than significant. 3 Calepa website, accessed June 1, 2009 at: http: /wuw. disc. ca. gov /SiteCleanup /Cortese_List.cfm 6 City of Pleasanton, General Plan, page v -11, August 6, 1996, as amended by the voters.
