Former Sunland Oil Refinery, 2152 Coffee Road, Bakersfield, California I KCEHSD Well Permit Numbers MW5103-05 through MW5126-05 Dear Ms. Warren: ' I The Source Group Inc. (TSG), on behalf of World Oil Corp. (World), is pleased to submit the enclosed well completion'documentation for the monitoring and remediation wells recently I installed at the former 'Sunland Refinery and the PG&E Kern Steam Plant located northwest of the Sunland Refinery, in Bakersfield, California. This transmittal includes a site location map (Figure 1), well location maps (Figures 2 through 4), copies of the approved well permits, and I boring/well completion Icg for the groundwater monitoring and remediation wells installed. Well installation activities, which took place between March 2 and April 23, 2004, included the I installation of four groundwater monitoring welt clusters, four triple-nested air sparge wells, and thirteen soil vapor extraction (SVE) wells. The groundwater monitoring wells, air sparge wells and seven of the SVE wells were installed at the PG&E Kern Steam Plant. The remaining six SVE wells were installed on site at the former Sunland Oil Refinery. All wells were installed by I Prosonic Corporation (C-57 #756217) Signal Hill, California. Drilling and well installation work of TSG was overseen by an on-site qualified geologist working under the direct supervision of a California Registered Geologist(R.G.), or was directly overseen by an R.G. working in the field.
