Page 8 ~'� ..i Approximate 80-Acre Property September 25, 2001 Job No. 1107-013 information enumerated in the SCOPE OF {VORK section of this report. The search radius for each of the government agency listings meets or exceeds the referenced 2000 ASTM standard for Phase I environmental assessments. EDR DATABASE SEARCH General EDR maintains a large database of environmentally relevant Federal, State and County information. At our request, EDR performed a search of their database for relevant information and listed sites situated within the vicinity of the subject property. The scope of the database search both meets and exceeds the referenced ASTM standards for Phase I environmental assessments. The results of our review of the agency data are discussed below. Identified Vicinity Sites EDR identified no sites listed by Federal and State government agencies within about one-half mile of the subject property; the actual EDR report is presented in the Appendix. The only listed site within one mile of the property is the Harney Lane Landfill located at 1470 East Harney Lane, approximately 4850 feet westerly of the subject property. An underground tank leak was reported in 1989 at this site, reportedly affecting the underlying soils only. The incident was investigated and/or remediated and subsequently closed by the County. "Orphan" Sites The environmental agency database listing includes a number of listed sites in San Joaquin County that EDR could not locate due to apparent insufficient address information. Our review of EDR's "Orphan Summary" revealed no sites meeting the above criteria and the referenced ASTM guidelines. CONCLUSIONS AND RECOMMENDATIONS We have performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E 1527 for the subject property. This assessment has revealed no evidence of recognized environmental contaminant conditions in connection with past or present use of the subject property. Review of readily available historical aerial photography and topographic maps suggest that the property has been used for agricultural (mostly livestock grazing) and rural residential purposes for more than 50 years. A number of smaller containers of household chemicals, paints, gasoline, as well as several abandoned automobile batteries were observed within the area of a small residence on the northeast comer of the property. A 55-gallon drum of motor oil (partially filled) was noted within the barn at this location. The drum has leaked onto a concrete slab within the barn. A concrete wash basin was observed easterly of the barn; the wash basin was tilled with used paint and motor oil. No evidence of leakage or significantly impaired soil conditions was noted near the wash basin. Proper removal of all hazardous chemicals is recommended prior to any demolition activities.
