Acacia Street <br /> Tracy, California 95376 <br /> Clayton Proposal No. 93-B-110 <br /> Subject: Site Investigation for Underground Storage Tanks Removed in 1987: One <br /> 2,000-gallon Diesel and One 10,000-gallon Formaldehyde <br /> Dear Mr. Rieger: <br /> This proposal is based on our telephone conversation of March 25, 1993, and Clayton <br /> Environmental Consultants' site walk of March 30, 1993. <br /> BACKGROUND AND PROJECT UNDERSTANDING <br /> Clayton has been advised by Fortifiber that the tanks were removed on February 22, <br /> 1987, by Semco, a general engineering contractor from Modesto, California. The <br /> tanks were (1) a 2,000-gallon carbon steel diesel fuel tank and (2) a 10,000-gallon <br /> stainless steel tank that had been used for storage of formaldehyde. The stainless steel <br /> tank had not been used for several years prior to the removal and was empty when the <br /> removal was performed. <br /> Based on our review of information provided to us, it appears that four (4) samples <br /> were collected during the excavation process, three soil and one water. The water <br /> sample analysis reported 1,500 milligrams per kilogram (mg/kg) of diesel, however, <br /> another sample collected on April 17, 1987, reportedly from the same area did not <br /> detect any diesel. <br /> With the exception of reported low levels of motor oil in the 2,000-gallon tank soil <br /> sample, all other samples reported contaminants at nondetect above the detection <br /> level. <br /> It did not appear that any of the samples were analyzed for formaldehyde. <br /> Formaldehyde is a listed hazardous material under state and federal standards, <br /> 1kry <br /> Gayton Environmental Consultants,Inc. • A Marsh&McLennan Company • Detroit + New York/Newark • Atlanta • San Francisco <br /> Los Angeles + Honolulu • Boston • Windsor,ON • Toronto + Birmingham,U.K. + London,U.K. 0 Sauthampton,U.K. <br />
