"I <br /> Subject: Limited Preliminary Endangerment Assessm <br /> L',"MIf/8ERviu .a <br /> Former Great Western Chemical Facility <br /> 826 South Center Street <br /> Stockton, California <br /> Dear Ms. Johansen: <br /> This letter contains the additional information you requested <br /> during our telephone conversation of June 8, 1992, regarding <br /> modifications to the June 1, 1992 Work Plan for the above- <br /> mentioned site. <br /> Oxidizer Storage Area <br /> Information provided to Levine-Fricke by Great Western <br /> indicates that an area of the site was used to store nitric <br /> acid. Therefore, we will analyze the soil sample collected <br /> from that area for pH only. <br /> Background Sample <br /> As the DTSC has requested, we are planning to sample soil for <br /> pH analysis in an area of the site where soil is the least <br /> likely to have been affected by previous site operations. <br /> Depth of Soil Samples <br /> The Work Plan originally proposed collecting two soil samples <br /> at each sampling location, one sample at 0.5 feet below ground <br /> surface (bgs) and one at 2.0 feet bgs. Instead, as requested, <br /> samples will be collected at 2.0 feet bgs and 3 .0 feet bgs. <br /> The samples collected at 3 .0 feet bgs will be held at the <br /> laboratory pending analysis of the samples collected at 2 .0 <br /> feet bgs. <br /> 1900 Rowell Street, 12th Floor <br /> Emeryville,California 94608 <br /> 26117WOMMI.ETT:CdH (510)652-4500 <br /> Fax(510)652-2246 <br /> Other offices in Irvine.CA;socramento/Roseville,CA;Tallohossee,FL;Honolulu,HI <br />
