The site is located near the southwest corner of Beechnut Avenue and <br /> Forest Hills Drive as shown on Figure 1. The assessment was described in the Geomatrix <br /> ' 13 August 1996 letter work plan "Work Plan for Limited Soil Assessment, Alden Park/Renown <br /> Property, Tracy, California." The assessment was performed in the vicinity of historical pipelines <br /> associated with the former Standard Oil Company reservoir No. 56 above which Alden Park is now <br /> located. These pipelines carried locomotive fuel oil (Bunker Q. This work was performed voluntarily <br /> by CPL to evaluate potential property use. A permit to perform the work was obtained from San <br /> ' Joaquin County Public Health Services - Environmental Health Division (PHS-EHD) and a <br /> representative of PHS-EHD was present to observe field activities. <br /> ' The assessment consisted of advancing two soil borings and collecting soil samples for laboratory <br /> analysis at the locations shown on Figure 2. Sampling activities were performed on 16 August 1996. <br /> ' Sampling services were provided by Precision Sampling, Inc. of San Rafael, California. The soil <br /> borings were advanced to a depth of 8.5 feet below ground surface (bgs) using a continuous-core, <br /> ' direct-push sampling system fitted with brass sleeves. The sampling system produced 2-inch diameter <br /> borings that were backfilled with cement/bentonite grout after sampling was complete. Soil samples <br /> were retained for lithologic logging, field screening, and submittal for chemical analysis. <br /> ' Soil samples were logged using the visual/manual procedures described in the American Society of <br /> Testing and Materials method D 2488-90. Lithologic logs are included in Appendix A. Field screening <br /> ' procedures consisted of observing soil samples for visual evidence (discoloration) and olfactory <br /> evidence (odor) of petroleum hydrocarbons as well as measuring volatile organic compounds in <br /> ' Geomatrix Consultants, Inc. <br /> Engineers, Geologists,and Environmental Scientists <br /> ' 1 APROIEC nC3769\37fi9-2.DOC <br />
