Item No. 1 PC : 11-19-87 SU-87-22 Page 6 Parks: The project will increase the demand for park facilities. HAZARDS/CONSTRAINTS: Water Quality and Hazardous Waste: During the Traina Brothers hearing on September 10, 1987 , the Local Health District noted that traces of chloroform were evi- dent in water in this area. Consequently, the Health District is requesting that if individual wells are used on an interim basis, a test well is to be drilled to determine the water quality and availability before the final map is approved. The Tracy Defense Department is adjacent to the site on the northeast . The Local Health District has indicated that the Tracy Defense Depot is designated as a Federal facilities site under a scheduled clean-up work plan. State aw requires that if a project is within 2000 feet of a designated hazardous waste site, as is the case with this pro- posed subdivision, a "Border Zone Property/Hazardous Was o' Determination" is necessary. This determination by the �pJ D.epar-tmen-t of Health Services, Toxic Substance Control Division, must be made within one year prior to any construc- tion. Additionally, the State can impose development restric- tions as a result of the determination. _ A Condition of Approval addressing this issue has been developed by the Local Health District . ENVIRONMENTAL CONSIDERATIONS : An Environmental Impact Report (EIR) was prepared for the Traina Brothers General Plan Amendment . The Final EIR was certified by the Board of Supervisors on August 27 , 1987 . As part of the EIR certification, a Finding of Significant Impacts and a Statement of Overriding Considerations were adopted. The EIR also proposed mitigation measures to address potentially significant environmental effects which could be eliminated or reduced to acceptable levels. Conditions of Approval have been proposed to address these issues. The information about the chloroform in the groundwater came to light after the Final EIR was published. The potentially signi- ficant effects associated with this contamination are being miti- gated to a level of nonsignificance via the Local Health District ' s Conditions of Approval .
