Surface&Subsurface Contamination Report Page 13 700 W.Linne Rd.,Tracy Project No. 662.1 February 11,2013 in 1997 and the investigation was closed in 1999. No details of a remedial investigation were available to review in the County EHD records. According to the EDR report Paulson Farms operated up to 12 tanks on the Property, but county records do not confirm this. It is likely the EDR report is in error on this point. Several adjacent or nearby farms parcels were identified in the EDR database report as facilities that operated permitted underground fuel tanks, but none of the sites have reported a hazardous release. Sites of such tanks are identified 1777 W. Linne, 28855 S. Koster, 1560 W. Linne, and 29141 S. Koster. A site at 1660 W. Linne reported a surface release of fuel. The release was investigated, adequately mitigated, and officially closed. Based on the results of the EDR report, it was not deemed necessary to further investigate off-site facilities. 3.2 State Well Records The State Division of Oil, Gas, and Geothermal Resources maintains records of oil and gas drilling and production. Maps created by the agency indicate that three step-out gas wells were drilled on the Property as shown in the first site map of Appendix A. Documents specific to the wells (Appendix E) indicate Great Basins Petroleum drilled them beginning in 1970. One of the wells was abandoned as a "dry hole" and was abandoned in accordance with procedures established by the agency. The other two were completed as gas producers but are currently idle. According to DOG records, the wells were drilled in accordance with State standards intended to protect the public and groundwater aquifers. The documents are attached as Appendix E. 3.3 Local Records Sources Five sources of information were accessed at the local level. Files from the San Joaquin County Environmental Health Department, Agricultural Commission, Office of Emergency Services, and Assessor's Office were requested. Air photos were acquired at the San Joaquin County Public Works Department.

On January 25, 2013, the available records were examined at the agency offices at 1868 Hazelton in Stockton. Records pertaining to former underground fuel tanks and to the domestic water well and septic systems were found to review.
