Weber Avenue, 3rd Floor � 0 � <br /> Stockton, CA 95202 <br /> Dear Mr. Knoll: <br /> Re: Pacific Gas and Electric Company's (PG&E) Natural Gas Line 176 <br /> Pipe Break Post Cleanup Sample Results �� <br /> This letter is a submittal of the analytical results from soil sampling which were <br /> taken, during and after cleanup activities, due to a pipebreak on Line 176 in San <br /> Joaquin County, which occurred on January 9, 1997. Results of the laboratory <br /> analyses are listed as Total Petroleum Hydrocarbons (TPH) as Diesel, <br /> Kerosene, Mineral Oil, and Gasoline; Benzene, Toluene, Ethylbenzene, and <br /> Total Xylenes, or BTEX are also listed. <br /> At this time, all remediation activities have been discontinued at the request of <br /> the Reclamation District over concern of the integrity of the levee. <br /> As previously agreed, PG&E will take additional soil samples in June 1997. The <br /> additional samples will be collected at locations where the analytical results <br /> indicate levels exceeding 50 mg/kg TPH are still present. Additional soil may be <br /> removed after that time, if conditions warrant. We will contact you prior to June <br /> to give you the opportunity to witness the sampling. At that time, we will work <br /> with you to achieve the designated cleanup level. <br /> If there are any further questions or concerns concerning the attached laboratory <br /> analyses, please contact me at (510) 974-4079. Thank you. <br /> Sincerely, <br /> /(YA <br /> Rex Bell <br /> JDO:skw <br />
