MOUNTAIN HOUSE NEIGHBORHOOD"F"PROJECT INITIAL STUDY Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact h) Expose people or structures to a significant risk of loss,injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Environmental Checklist Explanations a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Some minor amounts of hazardous materials associated with construction could be transported through the project site. The number of people exposed to such potential hazards would depend on the phasing of construction. In the first phases of project development, no residents would be residing at the site. In later phases of construction, some hazards could be present in association with the use and storage of hazardous materials at the proposed industrial areas along the site's eastern boundary. Residential development would be located west of these areas and agricultural uses would be located to the east. Such hazards would be less than significant due to existing federal and state regulations which govern the use, transport and disposal of such materials. b) 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? A potential exists for public exposure to explosives, fire, or the release of hazardous materials during railway accidents on the railway line crossing the northern portion of the Mountain House site, about 2,500 feet north of the project site evaluated in this Initial Study. An Emergency Operations Plan has been prepared by the County(January 1998)to account for the procedures to be undertaken in the event of an emergency. The distribution list for the Emergency Operations Plan included the Mountain House Community Services District,the San Joaquin County Sheriff's Office, the San Joaquin County Office of Emergency Services, and the Tracy Rural Fire Protection District. No significant impacts requiring further mitigation would be likely related to a reasonably foreseeable upset or accident involving hazardous materials. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? The only use within one-quarter mile of the proposed elementary school site that could be associated with the emission of hazardous substances would be the proposed community recreation area that could include a large public pool. Chlorine tanks(gaseous form of chlorine)associated with this pool's disinfection system could create a potential hazard. If a leak occurred, a chlorine gas cloud could impact the neighborhood. Given existing industry standards and regulation, the potential for this impact would be less than significant. However, a Condition of Approval has been recommended to reduce the likelihood of such an accident. Condition of Approval HAZ-1: The disinfection system for the pool at the Neighborhood Recreation Facility shall be either liquid chlorine, bromine tablets, chlorine tablets, or other non- gaseous chlorine system of disinfection. The use, storage and transport of these materials shall be determined by applicable laws and regulations. Pool staff involved in water quality maintenance shall be educated and trained in the use of chemicals,proper storage and emergency response.
