i <br /> ARCO Meeting Minutes • <br /> August 8, 1994 <br /> Page 7 <br /> i <br /> ARCO 6100, Tracy, (Margaret Lagorio) <br /> Margaret asked ARCO what the status was on performing further off-site assessment to <br /> delineate gasoline hydrocarbons in soil. ARCO stated that they had submitted an access <br /> agreement to the owner of the property across Patterson Pass Road in June, 1993. The property 3 <br /> owner requested that the agreement be revised to address property restoration following <br /> completion of the investigation/remediation. The agreement was revised and resubmitted in April <br /> 1994. ARCO or EMCON has not received any word from the owner. ARCO said that they would a <br /> have EMCON resubmit the agreement for a third time. Margaret told ARCO to continue to include <br /> a <br /> the status of obtaining access in future quarterly status reports. <br /> t <br /> e <br /> The results of the depth to groundwater investigation conducted on the on-site production well <br /> was discussed. Margaret said she received a copy of the report presenting the findings of the <br /> investigation and is satisfied that groundwater beneath the site is under confined conditions and # <br /> is at a depth (deeper than 150 feet and likely 200 to 300 feet) that hydrocarbons in the soil would <br /> not impact groundwater. <br /> 3 <br /> ARCO 434, Lodi (Margaret Lagorio) <br /> BC sent a copy of the revised soil boring locations to Margaret. ARCO has received off site <br /> permission for the Church property to the north of the site and the proposed boring locations in <br /> the City of Lodi right of way. ARCO is pursuing but does not yet have permission for the borings <br /> on the south side of Kettleman Lane. Kyle says we should go ahead and schedule the drilling <br /> now and the County agreed. <br /> Margaret needs information concerning the Biofifter, specifically a description of the system and <br /> the results. BC will provide her with a copy of the papers that have been prepared for the <br /> system. Margaret indicates that she needs to be informed when modification to the system are <br /> being proposed and ARCO has provided notification via quarterly monitoring reports. <br /> Summary <br /> Should you have any questions or comments please contact me at (415) 571-2469 so that we <br /> can make adjustments. <br /> Sincerely, <br /> Chuck Carmel <br /> Environmental Engineer <br /> cc: Chris Winsor, PAC-1291 <br /> Kyle Christie, San Mateo <br /> Elizabeth Thayer, CVRWQCB <br /> Jay Johnson, EMCON <br /> Jay Lucas, Brown and Caldwell <br />
