Advanced <br /> Geo Environmental, Inc . <br /> 16 July 2009 <br /> AGE-NC Project No. 95-0184 <br /> Ms. Vicki McCartney <br /> San Joaquin County Environmental Health Department <br /> 600 East Main Street <br /> Stockton, CA 95202 <br /> Subject: Quarterly Status Update- Second Quarter 2009 <br /> LARRY'S AUTO <br /> 308 North Grant Street, Stockton, California <br /> Dear Ms. McCartney: <br /> On behalfofMr.Charles Skobrak,Advanced GeoEnvironmental,Inc.has prepared a quarterly status <br /> letter for 308 North Grant Street, Stockton, California. A ground water monitoring event was not <br /> performed during the second quarter,due to the current status the State of California Underground <br /> Storage Tank Cleanup Fund(USTCF), which funds the site's environmental cleanup.As the EHD <br /> may be aware, the USTCF has notified all claimants payments of reimbursement requests are <br /> delayed beyond"historical time periods." In order to elevate the issue of delayed payment by the <br /> USTCF, the State Water Resources Control Board(SWRCB) adopted Resolution No. 2009-0042 <br /> which directs sites to reduce ground water sampling to a semi-annual schedule. <br /> A soil vapor extraction(SVE)remediation system operated at the site until 07 February 2009.Due <br /> to excessive costs for remediation, Mr. Skobrak requested a suspension of corrective action(soil <br /> vapor extraction). Based on the SVE sampling event in January 2009 [total petroleum hydrocarbon <br /> as gasoline (TPH) were detected at 2,400 micrograms per liter (µg/1), toluene at 4.3 µg/1, ethyl- <br /> benzene at 7.6µg/1 and xylene at 50µg/1]the operation of the SVE remediation should be evaluated <br /> with the use of carbon adsorption, to reduce costs. <br /> Semi-annual ground water sampling of selected impacted, monitoring wells will be scheduled for <br /> the third quarter.
