The list of known fuel leaks from underground tanks, maintained by the Central Valley Regional Water Quality Control Board (CVRWQCB) in Sacramento, was not reviewed for leaking tanks or unauthorized spills within 2000 feet of the property. Normal public access to the files has been denied during the entire month of October due to a personnel shortage caused by the file custodian's vacation. However, the San Joaquin Public Health Service maintains an excellent list of the leaking tanks in the County, so this reference source was used in lieu of the CVRWQCB files. Interviews with local officials and residents were conducted where appropriate. The Cortese List of Identified Hazardous Waste and Substance Sites (January, 1989) was reviewed for listings of sites which could impact the property. The Abandoned Sites Program Information System (ASPIS), a division of the Department of Health and Safety in Sacramento, was queried for cases which may impact the site. CERCLIS (The database of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ,CERCLA) traces the status of suspected sites. This list was reviewed for cases within a one mile radius of the subject site. BEP (Bond Expenditure Plan) - a list of sites for which State bond funds will be spent either for total cleanup costs or for State oversight was reviewed for cases which could impact the property. The California Division of Oil and Gas, the California Division of Water Quality, and the California Waste Management Board were also contacted for information on cases which could affect the subject site. ON-SITE RECONNAISSANCE AND INVESTIGATION Reconnaissance The property has recently been scarified and graded for commercial development (refer to photographs). This has exposed most of the in-situ soils on the site. There is no evidence in the newly exposed surfaces of visible contamination or any prior excavations which could have been utilized for underground storage tanks or disposal of hazardous wastes. A visual survey of the subject site revealed no evidence of underground storage tanks. There were no physical signs of contamination such as abnormally stained soil or concrete, vegetation damage, foul or unusual odors, or oily sheens on water or ground surfaces . There is a BP service station with underground tanks on the southwest corner of March and West Lanes approximately 150 feet from the property. Active railroad right of ways exist approximately 1500 and 1100 feet east and west of the property. There are no electrical transformers which might contain PCB's either above or adjacent to the property. Investigation As required by Sanwa Bank, two test borings were performed on October 18, 1990 under permit from San Joaquin County Public Health Services (refer to Figure 3 and attachments). The borings were intended to document the absence of petroleum hydrocarbon contamination at the drill -2-
