I <br /> hk AM <br /> WO®I'VPR <br /> San Joaquin/ARCO Meeting Minutes, March 30, 1993 Working To Restore Nature <br /> E. Closure <br /> 1. definition: SJC indicated that they require destruction of all monitoring <br /> wells and completion of remediation (including removal of remedial <br /> equipment) before granting closure ; therefore, closure will not be <br /> granted on sites undergoing post-remedial monitoring; this will affect <br /> sites considered for closure on basis of RA/FI studies. <br /> 2, monitoring: no discussion <br /> 3, hydrologic cycle : no discussion <br /> 4. Basin Plan amendments: Beth Thayer stated that she is not aware of <br /> the status of the basin plan amendments ; she also stated again that <br /> federal and state involvement in the military base closures will have <br /> an impact. <br /> III. ARCO Sites (Environmental Consultant ; RESNA Industries) <br /> ARCO SS No. 2130, North El Dorado St. Stockton <br /> o Mike Infurna stated that he had just recently received the ground-water <br /> monitoring data for the fourth quarter 1992. He would like these reports to <br /> be submitted at least before the sampling date of the following quarter. <br /> o RESNA informed SJ that the results of the first quarter groundwater <br /> sampling event have been received and the quarterly monitoring report will <br /> be submitted in April . RESNA presented the ground-water results <br /> summarized on a plate. <br /> o Mike stated that the ground water in the two upgradient wells (MW- 1 and <br /> MW-4) has consistently reported moderate to hydrocarbons.hi h levels of He <br /> g <br /> asked when ARCO intended to assess ground water upgradient and <br /> crossgradient from these wells (i.e. across Hammer Lane and in the mall <br /> parking area). RESNA stated that access to drill in Hammer Lane would <br /> likely not be granted by Caltrans. SJ asked that an attempt should be made. <br /> o Mike inquired about the results of the air sparge pilot test which was <br /> conducted in December 1992. RESNA informed SJ that the data are <br /> currently being evaluated and a final report would be submitted in April. <br /> Preliminary evaluation indicates that air sparging may be a feasible method <br /> of remediation. <br /> 3 <br />
