�'� KLEINFELDER 7 FINDINGS AND CONCLUSIONS The purpose of this assessment was to recognize environmental conditions associated with the present or past usage, storage, or disposal of hazardous substances or petroleum hydrocarbons at the subject site. The findings of this environmental assessment are presented below, and are based on Kleinfelder's knowledge of the subject site from our site observations and information gathered during our review. These findings are subject to the limitations presented at the end of this report, and may change if additional information becomes available. 7.1. BACKGROUND According to the aerial photograph review, the western portion of the subject site has been used as a fallow field with no structures. Thornton Road is present trending north/south, connecting the two portions of the site. The eastern portion of the site has been used as a vacant field and a vineyard(approximately the northern 15 acres). 7.2. FINDINGS AND CONCLUSIONS Based upon the results of our research, Kleinfelder makes the following observations regarding the site. 1) On properties with a history of agricultural use, many underground pipelines may exist. It was common for said pipelines to contain asbestos (e.g. Transite pipe). Subsurface exploration is not a part of our scope of work for this project. In the event that any subsurface structures are encountered during site development or excavation on site, care should be exercised in determining whether or not the subsurface structures contain asbestos. If they contain asbestos, they should be removed, handled, transported, and disposed of in accordance with local, State, and Federal laws and regulations. Additionally, if suspect materials are encountered,the signatories of this report should be notified. 2) Based upon Kleinfelder's review of aerial photographs and the observation made during the i site reconnaissance, the agricultural use of the site consisted of a vineyard and dry crop grain field. Agricultural chemicals may have been applied to the site. No chemical mixing or storage areas were noted on site or in aerial photographs. Normal agricultural chemical usage as part of crop production does not generally trigger enforcement action by regulatory agencies and is therefore not considered a "recognized environmental condition." Surface soil samples could be collect to further evaluate this issue if desired. 3) The subject site does not appear on the regulatory agency databases reviewed: A single site exists within the ASTM minimum search distances to the site. The "listed" site is not anticipated to pose an adverse impact to the subject site for reasons discussed in the body of this report. 20-1415-17.P01/2000F 542 Page 18 of 20 Copyright 2000 Kleinfelder,Inc.
