July 21, 1999 <br /> NOA ENVIRONMENTAL D.R.0m T NUMBER E99130 <br /> 7. California Department of Conservation, Division of Oil, Gas <br /> and Geothermal Resources <br /> The California Department of Conservation, Division of Oil, Gas and Geothermal Resources <br /> (DOGGR)was contacted in person in an effort to determine whether any oil or gas wells exist on the <br /> subject property. According to records at the DOGGR, there is one abandoned well located on the <br /> subject property. Copies of the records obtained from the DOGGR are attached to this report as <br /> Appendix D. The information obtained from the DOGGR relative to the abandoned well is <br /> summarized as follows: <br /> The Venada Drillco "Venada—1" abandoned well is located 560 feet south and 735 feet west from <br /> the northeast corner of Section 29, Township 2 South, Range 7 East, Mount Diablo Baseline and <br /> Meridian. The drilling of the well commenced on August 24, 1974. The well was drilled to a depth <br /> of 6386 feet. The well was reported to never have produced and was identified as a"dry hole". The <br /> well was plugged with cement and abandoned on October 30, 1974. The Report of Well <br /> Abandonment was dated April 8, 1975. The Report of Well Abandonment indicated that "A review <br /> of the reports and records shows that the requirements of this Division, which are based on all <br /> information filed with it, have been fulfilled." <br /> 8. Pacific Gas & Electric Company <br /> The Pacific Gas& Electric Company (PG&E) was contacted by telephone in an effort to obtain <br /> information relative to the PCB content of the five (5) pole-mounted transformers located near the <br /> northern property boundary in an easement along West Ripon Road. A blue sticker was observed on <br /> two of the transformers which indicates that they are PCB free. Two other transformers appeared <br /> to be newer; however, blue stickers had not been placed on these transformers. One transformer <br /> appeared to be older and was painted black. All of the transformers appeared to be in good condition. <br /> No leakage from the transformers was observed, and no staining of the soil around the poles beneath <br /> the transformers was observed. <br /> According to Mr. Don Hellier at PG&E, they have no records relative to the PCB content of the <br /> fluids in the three pole-mounted transformers that do not have blue stickers. Mr. Hellier indicated <br /> that most PCB containing pole-mounted transformer fluids in San Joaquin County have been replaced <br /> with non-PCB containing fluids through a voluntary PG&E statewide reduction program which took <br /> place from 1976 to 1978. However, the only way to accurately determine the PCB content of the <br /> fluids in the transformers would be to have them tested. It should be noted that the transformers are <br /> owned by PG&E, which would be responsible for any cleanup if a leak occurred. <br /> 9 <br />
