<br /> .. scope of work. In the event that any subsurface structures are encountered during site
<br /> development or excavation on site, care should be exercised in determining whether or
<br /> not the subsurface structures contain asbestos. If they contain asbestos, they should be
<br /> �- removed, handled, transported, and disposed of in accordance with local, state, and
<br /> federal laws and regulations. Additionally, if suspect materials or other sub surface
<br /> structures are encountered, the signatories of this report should be notified immediately.
<br /> 2) The site has a history of agricultural use, and agricultural chemicals such as
<br /> L environmentally persistent pesticides may have been applied to crops previously grown
<br /> on-site. Kleinfelder recommends that shallow soil sampling for environmentally
<br /> persistent pesticides be conducted, throughout the site.
<br /> 3) A monitoring well and industrial well/fire well is located on the western border of the
<br /> subject site. Kleinfelder recommends that the industrial wells be sampled and the water
<br /> analyzed in accordance with intended use, and the monitoring well be continually
<br /> sampled in according with water discharge requirements. If the on site wells are not
<br /> planned for future use, Kleinfelder recommends proper abandonment and closure in
<br /> accordance with local, State and Federal regulations. Kleinfelder recommends current
<br /> ` testing of the onsite monitoring well to evaluate potential impacts to groundwater from
<br /> the adjacent Owens Illinois facility and petroleum pipelines traversing the site.
<br /> 6. 4) Owens-Brockway Glass Container, Inc. (AKA Plant #22), located at 14700 West Schulte
<br /> Road, adjacent and east of the subject site appears on the Cortese, LUST, CA WDS,
<br /> ` AST, CA SLIC, TRIS, RCRIS-LQG, FINDS, and CA FID databases. According to files
<br /> reviewed Owens-Illinois reportedly maintains two underground sumps (42,000, and
<br /> 27,3000 gallons) and four underground storage tanks (UST) (3,150, 300, 450, and 1500
<br /> ` gallons) on site. Based upon interviews with current employee(s) (Robert Mair), He
<br /> stated that there are two large sumps (27,000 and 42,000 gallons) partially below ground
<br /> and five sided that contain animal fats. When questioned regarding information about a
<br /> L 450-gallon and 3,150 gallon UST, Mr. Mair stated that they were improperly identified
<br /> by the SJ EHD and were actually the 300 gallon and 1,500 gallon tanks which were
<br /> removed and closed in place, respectively. According to the SJEHD, case closure
<br /> summary some conflicting documentation did exist about the size of 300 gallon UST. No
<br /> records of the miscommunication were available or obtained for the 1,500 gallon UST.
<br /> Kleinfelder recommends that the client follow up with the San Joaquin County
<br /> V, Environmental Health Department to confirm that all underground storage tanks located
<br /> within the Owens-Illinois facility are accounted for, and a closure letter be obtained for
<br /> the 1,500 gallon (1,460 gallon) waste oil tank which was closed in place. If additional
<br /> 6. USTs are discovered through additional research soil sampling may be warranted.
<br /> During file review for offsite properties, Kleinfelder briefly reviewed a groundwater
<br /> characterization workplan for the adjacent Owens Brockway Glass Containers facility,
<br /> .. dated August 11, 2000. This workplan included groundwater information from three
<br /> monitoring wells, one of which is location on the subject site (MW-2). Kleinfelder noted
<br /> exceedences of some water quality goals (WQGs) relevant to drinking water standards
<br /> r+ compiled by the California EPA, in the monitoring wells including the onsite monitoring
<br /> well MW-2. Petroleum constituents toluene, ethylbenzene and total xylenes have also
<br /> been detected MW-2, but at relatively low levels compared to WQGs. Based on these
