PHS/EHD has the following comments for your consideration. <br /> The work plan proposed the drilling and sampling of three soil borings to further investigate residual soil <br /> contamination documented during the May 18, 1994 over excavation. Two of the soil borings will be <br /> drilled vertically to a total depth of approximately 20 feet. The third soil boring will be drilled at a 45 <br /> degree angle to a total vertical depth of 20 feet. Soil samples will be collected every five feet for <br /> geological description: A minimum of two soil samples will be collected from each borehole for laboratory <br /> analysis. <br /> PHS/EHD concurs that the proposed soil borings should investigate the extent of soil contamination based <br /> on available information. In addition to the analysis for BTEX, TPH-g and EDB described in the <br /> workplan, PHS/EHD suggests that contaminant leachability testing be performed (WET or TCLP) on <br /> some samples. Once the extent of contamination has been determined it may be necessary to develop a <br /> remedial action plan. <br /> Please submit the S89*e for the drilling soil boring permit application submitted. Field work may <br /> commence upon issuance of the drilling permit. Please,provide PHS/EHD 48 hours notice prior to <br /> initiating Feld activities, so that PHS/EHD can witness soil sampling and grouting. <br /> If you have any questions or comments, please contact Mary Meays of my staff at (209) 468-0337. <br /> Donna Heran, RENS; Director <br /> Environmental Health Division <br /> V <br /> Mary Meays, Senior REHS Diane on, REHS <br /> Site Mitigation Unit Supervisor <br /> MM:lb <br /> N <br /> c: Elizabeth Thayer, CVRWQCB <br /> c: Keith Tallia, Oil Equipment Services <br /> c: Marc Crum, Condor Environmental <br /> A Division of San.loaquin County Health Care Services <br />
