The property has been owned by Mossdale Associates since 1985. Prior ownership was by the Windler family. The region has been dry-land and irrigated farmed, particularly in row crops and pasture for the last several decades. Surrounding irrigation is provided from irrigation wells and the San Joaquin River. An on-site domestic well and septic system serves the mobile home located near the office and truck scales. Storm drainage flows to the interior limits of excavation and to the farmland at the northeast and southwest. The property is subject to flooding, which was evident during the winter of 1997. STANDARD PUBLIC ENVIRONMENTAL RECORD SOURCES County and State environmental records were reviewed for sites which may have impacted the subject property. The databases accessed did not indicate a problem or potential problem with the subject property. Possible environmental impact from a commercial facility was noted - specifically the Exxon gas station near the northwest comer of the property. According to records reviewed at the San Joaquin County Environmental Health Department, the following information was obtained: This Exxon gas station is owned by Mr. Nick Bokides. On March 1, 2000, a Preliminary Investigation and Evaluation Report(PIER) was conducted by Advance GeoEnvironmental (AGE) of Stockton, CA. Based upon data collected during their October and November 1999 investigations, AGE recommends the installation of groundwater monitoring wells to determine the groundwater gradient, flow direction and the concentration of chemicals in the water. This effort would be to assess the lateral extent of petroleum hydrocarbon impact to the underlying groundwater. There are two primary sources of information which document and define past land use, although they are sometimes difficult to interpret. The first is the use of aerial photographs. Aerial photographs of the subject area in the 1970's from USDA Soil Maps indicate no structures on the subject property. The fruit stand west of I-5, the Exxon (formerly Texaco) gas station and the Mobile Home Park are visible on the aerial photo. The second source of information can be found on USGS maps. A 1952 USGS quadrangle map for this area indicates the aforementioned structures, and no other buildings. There was a photo revision of this USGS map in 1987 and a minor revision in 1994. INFORMATION FROM SITE RECONNAISSANCE AND INTERVIEWS The following information was obtained visually and/or through an interview and on-site inspection with Mr. Mike Brown on June 6, 2000: The subject property contains no underground storage tanks (USTs). There are two above ground storage tanks (ASTs) containing diesel which are used to fuel machinery. There was no spillage under these tanks and each tank had double- wall containment. 2 Vafky Ag Research
