Box 2009 <br /> San Joaquin County, California 95201 <br /> Re: Disposition of Stockpiled Soil, John Taylor Fertilizer, Stockton, California <br /> Dear Ms. Heran: <br /> EMCON is providing information regarding the disposition of stockpiled soil generated <br /> during removal of three underground storage tanks (USTs) on October 18, 1991, at the <br /> John Taylor Fertilizer (JTF) facility, 1819 South Argonaut Lane, Stockton, California. <br /> EMCON understands this information is required for completing site closure. <br /> Approximately 50 cubic yards of soil generated during UST removal activities were <br /> reportedly contained in three stockpiles (SP-1, SP-2, and SP-3). Soil samples were <br /> collected for characterization. Petroleum hydrocarbons were not detected in soil samples <br /> collected from SP-1. The soil sample collected from SP-2 contained 230 milligrams per <br /> kilogram (mg/kg) oil and the soil sample collected from SP-3 contained total petroleum <br /> hydrocarbons as diesel (TPHD) at a concentration ef-7!0 g/kg. The soil stockpiles were <br /> subsequently moved to a different part of the site. �. <br /> The San Joaquin County Department of Health Services (SJCDHS) issued a letter dated <br /> December 17, 1993, requesting soil disposition information required to complete site <br /> closure. JTF responded with a letter dated August 5, 1994, indicating the soil was on-site <br /> and would be profiled for disposal. <br /> EMCON conducted a site visit on October 19, 1994, to locate the soil and collect <br /> samples. JTF personnel identified approximately 30 cubic yards of soil corresponding to <br /> the impacted soil previously contained in stockpiles SP-2 and SP-3. The disposition of <br /> unimpacted soil contained in original stockpile SP-1 is unknown. <br /> EMCON assigned a sample designation of SP-1 to the stockpile and collected four soil <br /> samples. Sampling procedure consisted of removing approximately 1 foot of soil at each <br /> location and driving a stainless steel tube into the soil stockpile. The sample tubes were <br /> sealed with Teflon" tape and plastic end caps and placed in an ice chest for transport, <br /> along with chain of custody documentation to a state-certified analytical laboratory. <br /> SA(�N:V'JZ\2527\25271000.1 AL-Mfc:2 <br />
