Karen Petryna <br /> Shell Oil Products <br /> 880 E. Victor Rd., Stockton, CA <br /> Page 5 of 5 <br /> reevaluated. The reported 92.9 milligrams per kilogram (mg/kg) MTBE at 25 feet <br /> bsg in SB-1 suggests that a significant mass of MTBE resides in the vadose zone <br /> soil. Please provide EHD an estimate of the mass of MTBE in the vadose zone <br /> soil and an estimate of the potential impact to groundwater posed by the mass. If <br /> the MTBE has potential to cause additional impact to groundwater, SVE should <br /> be reevaluated with a new vapor extraction well(s) located within the plume of <br /> impacted soil. You are directed to provide EHD a report of your reevaluation of <br /> the potential benefit of utilizing SVE on your site and include the requested <br /> related data with a proposed course of action by 03 January 2005. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department <br /> C(.-P � H <br /> e*yondg�Senior REHS Nuenderson,nderson, RG <br /> LOP/Site Mitigation Unit LOP/Site Mitigation Unit <br /> C: CRWQCB, Central Valley Region — James L.
