KLEINFELDER • Doornanbal Farms, located at 14744 Carrolton Road, adjacent to the northeast of the subject site, appears on the HIST UST database. • Dairies are located to the north, east and west of the subject site. 8.2. CONCLUSIONS AND RECOMMENDATIONS We have performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E 1527-00 of the property located south of Lone Tree Road, east of Carrolton Road, west of Van Allen Road and north of Zummalt Road, located northwest of Escalon, California. The subject site is approximately 410- acres in size and at the time of Kleinfelder's site reconnaissance the site consisted of orchard, row crop, a dairy and rural residences. Any exceptions to, or deletions from this practice are described in Chapter 8.3 of this report. In summary, this assessment has revealed evidence of recognized environmental conditions in connection with the property: 1. Concrete irrigation control structures and standpipes are located though out the orchards in the southern portion of the site. On properties with a history of agricultural use, underground pipelines may exist. It was common for said pipelines to contain asbestos (e.g. Transite pipe). A transite standpipe was noted in the northeast corner of APN 205-100-17. Subsurface exploration is not a part of a typical Phase I Environmental Site Assessment scope of work. 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. Due to the historical agricultural use of the site it is possible that environmentally / persistent pesticides may have been applied to the site. If a greater level of inquiry is desired, Kleinfelder can perform soil sampling to evaluate potential residual pesticides in shallow soil. 3. Vanderschaaf, 15355 Van Allen Road, an address associated with the subject site, appears on the Statewide Environmental Evaluation and Planning System (SWEEPS UST) database. The USTs at this address are reported as a 350- i gallon diesel UST and a 350-gallon leaded fuel UST. According to the SJC/EHD UST file, two 350 gallon UST's were removed from the site in February of 1990. The tanks were a diesel and a gasoline tank. No violations are reported in association with this facility. These former USTs had limited information available from the county or from our owner/manager interviews.
