Petroleum hydrocarbons were detected in the soil at the <br /> site during removal of a section of two old crude oil pipelines by Chevron Pipeline Company in <br /> May 1995. The work plan was prepared in response to the results of the initial investigation by <br /> Raney Geotechnical, which identified seven areas of petroleum-affected soil along the old <br /> pipeline section. Our comments on the work plan are included in the enclosed memorandum. <br /> By 17 August 1995, please provide a supplement to the work plan which adequately addresses <br /> these comments, as well as an updated schedule for implementation of the investigation and <br /> preparation of a report of results. <br /> If you have any estions, you may call me at(916) 255-3141. <br /> - MOO <br /> Water Resources Control Engineer <br /> Enclosure <br /> JDM:j dm\lsb <br /> cc: Ms. Margaret Lagorio, San Joaquin County Public Health Services, Stockton <br /> Mr. Kevin Smith, Rural California Housing Corporation, Sacramento <br /> Mr. George Forsythe, EMCON, Fresno <br />
