KLEINFELDER • The produce stand and residential trailer located north of the produce stand, and office trailer ` and shed associated with the fish ponds all appear to have been built prior to the 1980's and may contain asbestos containing building materials and/or lead based paints. Kleinfelder recommends that an asbestos and lead based paint inspection be performed on these structures by a certified Cal-OSHA qualified inspector, if the structures are to be demolished prior to site development Please note the other Conclusions and Recommendations in Kleinfelder's Phase I Report for the subject site are either general recommendations or statements for the property, related to offsite ` properties, or were not requested to be addressed by the client at this time. The first two bulleted items are addressed in this report. The last bulleted item recommending lead and asbestos sampling will be addressed in a separate report. The following documents Kleinfelder's findings. FIELD ACTIVITIES AND ANALYTICAL RESULTS Field activities included soil sampling in field areas and beneath an old pole-mounted transformer. Initial sampling was conducted in the vicinity and beneath three AST's in the building area of the site. Based upon the initial results, soil was excavated beneath the AST's and sampling conducted within the excavation and excavated soil. Aericultural Soil Sampling (Field Areas) ` Between April 10 and April 12, 2003, twenty-five discrete soil samples were collected in the field areas of the subject site (Plate 2). One of the discrete sample (PMT-1) was collected beneath an old pole-mounted transformer at a depth of approximately 0 to 6-inches directly beneath the transformer. Twenty-four (24) discrete soil samples were collected over approximately 230 acres of the site (eight 3-point discrete subsets Cl through C8). The soil samples were located in approximately equal portions of the site in an attempt to collect representative samples of the subject site. The discrete composite subsets were also located in differing crop areas identified in aerial photos from Kleinfelder's Phase I report. These soil samples were collected at depths ranging from 0 to 12-inches. Grasses, weeds and miscellaneous .. vegetation were removed prior to collecting the discrete soil samples. Actual soil sampling locations were also based on accessibility. Soil samples were obtained by slide hammering a 2-inch diameter by 6-inch long stainless steel tube into the soil at the desired sampling depth. The stainless steel tube was then removed from the boring and sealed with Teflon sheeting and tight-fitting plastic end caps. The samples were immediately stored in an iced cooler. The samples were transported under chain-of-custody control to Kleinfelder's office and then transported by courier in a sealed container to a state certified laboratory for the requested analyses. The stainless steel sampling equipment and sample tubes were decontaminated between sample locations with a Liquinox (laboratory-grade detergent) and potable water wash and a distilled r 21073/ST03RI067 July 28,2003 '� 0 2003 Kleinfelder,Inc.
