STATE OF CALIFORNIA - Environmental Protelo, Agency <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD PETE WILSON, Governor <br /> CENTRAL VALLEY REGION .a <br /> 3443 Routier Road, Suite A . <br /> Sacramento, CA 95827-3098 <br /> PHONE: (916) 255-3000 I_y# OCT 28 PZ9 3: 05 <br /> FAX: (916) 255-3075 <br /> 26 October 1994 <br /> Mr. Don O. Culbertson <br /> Chevron Pipe Line Company <br /> 5080 California Avenue, Suite 400 <br /> Bakersfield, CA 93309-1671 <br /> WORK PLAN FOR ADDITIONAL SITE ASSESSMENT, FORMER CHEVRON LYOTH <br /> LOADING STATION, TRACY, SAN JOAQUIN COUNTY <br /> I have reviewed the 10 October 1994 amended Work Plan for Additional Site ASSCSsm272t prepared <br /> by your consultant EMCON Associates. The amended work plan includes some of the additional <br /> site investigation requested in my 1 September 1994 letter. I have the following comments: <br /> 1. A schedule needs to be submitted including dates the field work will be conducted and a report <br /> of findings submitted to the Board. <br /> 2. In my 1 September 1994 letter, I requested additional investigation along the old piping <br /> between the former above ground storage tanks, but the work plan does not include borings in <br /> this area. I had requested an investigation in this area because of petroleum residue and large <br /> buried pipes seen in a trench on 17 May 1994. The trench was part of a construction project <br /> installed by the Hoffmans which, on the base map of the former Lyoth Loading station, ran <br /> approximately between the testing house and the pump house. <br /> 3. Once the ground water monitoring wells are installed, water level measurements from all <br /> monitoring wells should be plotted on a map showing the ground water gradient and direction. <br /> The amended work plan is hereby approved on the condition you submit an adequate response to <br /> these comments and a time schedule by 15 November 1994. If you have any questions, you may <br /> contact me at (916) 255-3054. <br /> DAVID E.
