STANDARD PUBLIC ENVIRONMENTAL RECORD SOURCES County and State environmental records were reviewed for sites which may have impacted the subject property. The databases accessed indicate a potential problem with the underlying `groundwater originating from the Harney Landfill. There were no other sites of concern indicated. Environmental impact from the defunct Harney Landfill Station is unknown at this tir e. It is conceivable that ere may be groundwater impact in the future. The Arismendi's have owned the property for approximately twenty five years. Due to this length of ownership,prior owners of the subject property were not investigated. Past surrounding land use has been agricultural production and very low density residential, ranches and ranchettes. Records at the San Joaquin County Agricultural Commissioner's office indicate vineyards and pasture are the predominate crops grown in this area. There are three primary sources of information which document and define past land use, although they are occasionally difficult to interpret. The first is the use of aerial photographs. Aerial photographs of the subject area in the 1950's and 1960's located at the University of California at Davis indicate no changes in the subject property, as best as could be determined. The second type of information are United States Department of Agriculture aerial photos (See Appendix). The 1971 map illustrates the referenced house and a hay barn on the subject property. The United States Geological Survey map illustrates the contour of the property,the house and hay barn. INFORMATION FROM SITE RECONNAISSANCE AND INTERVIEWS The following information was obtained visually and/or through an interview with Mr. Luis Arismendi: The subject property contains no underground or above ground liquid fuel storage tanks (USTs/ASTs). There is an on-site, conventional septic system with a tank, leachfield area and seepage pits (assumed). There were no containers noted on-site. The subject property was surveyed for evidence which is indicative of surface and/or subsurface contamination: There are no transformers on-site. Therefore, there is no concern of polychloride biphenyls (PCBs) contamination. There was no evidence of solid waste disposal. The site was carefully inspected for environmental concerns originating from discolored, disturbed or subsided soils, stressed vegetation or unusual or noxious odors. None of these environmental indicators were present. No hazardous materials are stored in the referenced detached garage and there was no indication or observations of spills, drums or other items associated with hazardous materials in or around this garage. 2 Vaffey Aq P,�searck
