Quik Stop Market No. 132 <br /> 3555 West Hammer Lane Page 2 <br /> Stockton, California 95209 September 23, 2008 <br /> S132 in July 2001. Therefore, it must be demonstrated that the vertical extent of the <br /> contamination has been defined, as well. <br /> In October 1990, excavation of contaminated soil in the north dispenser island area <br /> occurred and soil sample QS-2 was collected at 10 feet bsg. Analytical results of that <br /> sample showed 3,300 milligrams per kilogram (mg/kg) of total petroleum hydrocarbons. <br /> This concentration exceeds the San Francisco Bay Regional Water Quality Control Board <br /> Environmental Screening Levels for gross contamination and indirect exposure. <br /> Excavation was performed in November 1990 of the area beneath the underground <br /> storage tanks and the dispensers; however, sampling in the area of QS-2 was not <br /> performed. The issue of remaining soil contamination must be addressed. <br /> The Quarterly Groundwater Monitoring Report, Third Quarter 2005, dated September <br /> 30, 2005, prepared by ATC Associates Incorporated for the site, recommended that the <br /> site be considered for closure and stated a formal closure request would be submitted. A <br /> closure request and report have not been prepared for this site. A large amount of data <br /> has been obtained for this site. If your consultant believes the contamination at this site <br /> has been defined laterally and vertically in soil and groundwater, then a closure report <br /> that includes the items discussed in the CVRWQCB Tri Regional Guidelines should be <br /> prepared and the above comments and concerns of the EHD should be addressed in that <br /> report. <br /> If you have any questions regarding this letter, please contact Vicki McCartney at (209) <br /> 468-9852 or by email at vmccartney@sjcehd.com. <br /> Sincerely, <br /> Victoria L.
