n KLEINFELDER <br /> With the exception of heavy metals, the analytical results in the Debris Area were <br /> also unremarkable. However, heavy metal concentrations, particularly lead were <br /> found at elevated concentrations ranging from 273 to 1610 ,mg/kg (parts p <br /> er <br /> million). Based on these values some of eed aobbe dis osed of atris may-'be lfiaeClass I <br /> as a <br /> hazardous waste for disposal purposes or n p <br /> disposal facility (Hazardous Waste Facility). Since evidence of building materials <br /> was found associated with the debris piles, the potential exists for said building <br /> materials to contain asbestos. Assuming development of this area, Kleinfelder <br /> recommends evaluating the extent of debris, further characterization of the <br /> debris to ascertain if the material is hazardous, designated waste or non- <br /> hazardous for disposal purposes, and removal to an approved disposal facility. <br /> At this time the Debris Area is not suitable for the proposed residential <br /> development <br /> • Significant cut and fill areas have been noted at the site. Although Kleinfelder <br /> has evaluated a large fill area west of the stands, other areas have not been <br /> evaluated for debris. Therefore, additional debris could be encountered in future <br /> grading and development of the site. In the event debris, unusual odors or soil <br /> discoloration is noted in these areas, the signatories of this report should be <br /> contacted. <br /> • Kleinfelder recommends that a copy of this report be submitted to San Joaquin <br /> County Public Health Services Department Environmental Health Division <br /> (PHS/EHD) for their review and comment prior to future development activities. <br /> For additional discussion of Kleinfelder's findings please refer to the "Discussion of <br /> Analytical Results, Conclusions and Recommendations" in Section 6. <br /> This report, and the conclusions and recommendations presented in this Executive <br /> t Summary, are subject to the "Limitations" presented in Chapter 7 of this report. Any <br /> other party (other than the Lagacy Development or regulatory agencies having <br /> enforcement jurisdiction for this site) who would like to use this report shall notify <br /> jKleinfelder, Inc. in writing for such intended use. <br /> 58671.E02/ST05R1127/DH:ly Page 2 of 22 <br /> ©2005 Kleinfelder, Inc.
