MOUNTAIN HOUSE NEIGHBORHOOD"F"PROJECT INITIAL STUDY pool operator shall prepare a training manual for review and approval by Countyfire and/or environmental health personnel. The design of the sanitation system shall be reviewed and approved by the County prior to issuance of the building permit for the proposed pool. d) 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 puhlic or the environment? The site is not included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. A farmhouse in the northeast corner of the site would be removed for project construction. An asbestos survey was performed for this house by Mr. James J. Butler(Certified Asbestos Consultant 97-2126) of Preferred Associates, LLC, Asbestos and Lead Consulting in April, 2000. Samples were collected and relatively small quantities of floor tile and sheet vinyl flooring containing asbestos were identified. Appropriate handling and disposal by the demolition contractor shall be required at the time of structural removal. Because the chrysotile is incorporated within the matrix of the sheet products, and generally non-friable, it was determined by the applicant's consultant that the abatement concerns were minor. Based on a site survey completed by Condor Earth Technologies, Inc. in 1998, additional soil and groundwater testing was completed in the area of the identified underground storage tank. The tank was removed in 1999 and appropriate testing was completed. Laboratory analyses indicated that none of the requested petroleum-related analytes were detected at or above the laboratory-reported detection limits in the soil sample collected from below the former underground tank. It was recommended that the site be considered for closure. New California legislation, effective January 2000, requires a Preliminary Endangerment Assessment (PEA)to be performed under the review of the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC), for those sites which may pose a hazard risk to students. DTSC has assumed that all Central Valley sites that have been historically farmed pose a potential hazard risk, regardless of the results of any Environmental Site Assessment done at a proposed school site. A Preliminary Endangerment Assessment was undertaken(May 2000) for the Neighborhood"I"' school site, with DTSC review expected by July 2000. A Condition of Approval is recommended below to clarify that the school shall comply with any requirements of the DTSC if any potential hazards are identified. Based on preliminary fmdings, the consultants for the PEA found no significant levels of hazardous materials at the school site. Condition of Approval HAZ-2: Prior to issuance of any grading permits, the applicant shall provide proof for the County Building Department that the demolition of the farmhouse in the northeast corner of the site shall be conducted with proper handling and disposal for materials containing identified asbestos, if any. Condition of Approval HAZ-3: The Lammersville School District shall comply with any requirements established by the Department of Toxic Substances Control(DTSC)for any hazardous materials at the proposed school site. Proof of such compliance shall be provided to the County Building Department prior to the issuance of building permits for the school. Condition of Approval HAZ-4: Based on the results of the 1998 study by Condor, the following measures shall be implemented prior to approval of the Final Subdivision Map: • Remove water well at northeast of site(proposed Lot 985)as per statement on Tentative Map. • Remove tailwater pond located within the site.
