Shell sites in San Joaquin County Page 2 2320 E1 Dorado Street Stockton EI-ID staff was not available to discuss this site. 2494 Fremont Street Stockton ARCO has been named as a responsible party for the site (2478 E. Oak Street) to the north of this site and will be investigating the extent of the contamination at that site. Shell should evaluate whether remediation is necessary and feasible on their site. 2375 Grant Line, Tracy Groundwater extraction by a vacuum truck from MW1 and MW6 is being performed monthly to reduce the concentrations of MTBE in these wells. A presentation was made by Dan Lescure that it was not cost-effective to continue the vacuum truck groundwater extraction events and that monitored natural attenuation should be considered. EHD requires complete definition of the contaminant plume to consider this alternative. Although down-gradient off-site assessment is impeded by the location of Hwy 205, further investigation down gradient, across Hwy 205 is required. 341 Main Street, Ripon CRA will correct the table in the Care Clontre Summary Report and upload the revised report to GeoTracker. Once EHD has received this report, EHD will proceed with providing the needed information to the Central Valley Regional Water Quality Control Board for case closure consideration. 7700 Moreland Street Stockton A closure report was submitted for review. 6131 Pacific Avenue, Stockton Dual-Phase extraction will be initiated once the City of Stockton issues Shell a permit to dispose of extracted groundwater to the city sewer. 3725 Tracy Blvd Tracy A closure report was submitted for review. 880 Victor Road, Lodi The temporary groundwater extraction system will continue to be operated since the contaminant plume is not defined to the south-southeast and the adjacent property owners to the south and east have not allowed monitoring welts to be installed on their property. Extraction of groundwater from 1VFW7 in the southeast corner of the property should be evaluated as a method to keep contam rants from migrating to the adjacent parcels. 4315. Waterloo Road Stockton EHD staff was not available to discuss this site. 1160 Yosemite Avenue, Manteca A work plan addendum will be submitted to EHD that will possibly include installing another monitoring well or advancing a CPT boring located north of the site to investigate the groundwater contamination north of IVRV-3 and MW-4. There are safety issues to consider since this site is located at a busy intersection in Manteca.
