A <br /> release of petroleum hydrocarbons has been evidenced during the operation of these tanks. PHSIEHD <br /> has also reviewed a bid from Jim Thorpe Oil to over-excavate a limited volume of contaminated soil, <br /> should it be warranted, at the time of tank removal. PHSIEHD has prepared the following comments. <br /> for your consideration. <br /> As an interim action, limited over-excavation, is an effective remedial alternative. PHSIEHD approves <br /> of the over-excavation and the off site disposal of a maximum of 200 cubic yards of contaminated soil. <br /> In lieu of the collection of six soil samples at the time of tank removal, soil samples must be collected <br /> at 20 foot intervals from the sidewalls and bottom following the over-excavation attempt. <br /> The residual soil contamination, if any, will be evaluated to determine if groundwater quality may be <br /> impacted in the future. Therefore, it may not be necessary to implement the "Site Contamination Work <br /> Plan" dated October 18, 1995 and prepared by Advanced GeoEnvironmental which proposed five soil <br /> borings, including three monitoring wells. <br /> Please notify me at least two working days, prior to initiating the tank removal process, so that I can <br /> make myself available to provide regulatory oversight during any over-excavation activities. If you <br /> have any questions or comments, please do not hesitate to contact me at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Mary Meays, Senior REHS Margaret Lagorio, REHS <br /> Site Mitigation Unit Lead Senior <br /> MM12402PAC <br /> cc: Elizabeth Thayer, CVRWQCB <br /> George Lockwood, SWRCS Cleanup Fund Unit <br /> Rich Thorpe, Jim Thorpe Oil <br /> A Division of San Joaquin County Health Care Services <br />
