EXECUTIVE SUMMARY Raney Geotechnical has completed Phase I environmental assessment of the subject property. Our research has revealed no evidence of pending environmental actions on or against the property. Our reconnaissance of the site did not identify any suspicious on-site environmental conditions or activities. 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 filled 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. The property presently supports domestic and irrigation water wells. If future developments on the property do not require the use of these wells, they should be abandoned properly in accord with state and local regulations. Our research of government agency information indicates that there have been no reported contamination conditions of a sufficient magnitude or proximity considered threatening to the environmental integrity of the subject property. In our opinion, no further environmental investigation of the subject property is warranted by available information. However, based on the age of the on-site residential structure, asbestos containing building materials may be present. The San Joaquin Valley Air Pollution Control District may require a survey of the building and the removal of regulated asbestos containing materials prior to any demolition activities. The California Occupational Safety and Health Administration (Cal-OSHA) requires that demolition contractors disturbing regulated quantities of asbestos containing construction materials have special licensing.
