" ?005 <br /> Mr. Jeff Cosgray _ ENVIRONMENT HEALTH <br /> Chevron Pipe Line Company PERMIT/SERVICES <br /> 2811 Hayes Road <br /> Houston, TX 77082 <br /> REVIEW OF WORK PLAN, CHEVRON PIPELINE,WEST GRANT LINE ROAD, TRACY, <br /> SAN JOAQUIN COUNTY <br /> Staff of the Central Valley Regional Water Quality Control Board(Regional Board)reviewed the <br /> 24 May 2005 2005 Chevron Pipeline Characterization Work Plan (Work Plan) submitted by SECOR <br /> International Incorporated on behalf of the Chevron Pipe Line Company(CPL) for the active Chevron <br /> Bay Area Product Line (pipeline)that runs along West Grant Line Road in Tracy. The Work Plan <br /> proposes to collect a groundwater sample from the nearest available existing monitoring well to analyze <br /> for jet fuel. The nearest available monitoring well is associated with the former Chevron Service Station <br /> 9-8632 located at 575 West Grant Line Road. <br /> Although Regional Board staff would prefer that the existing well not be associated with Chevron, upon <br /> review of information in Geotracker, the location proposed appears to be the closest site with existing <br /> monitoring wells to 541 West Grant Line. Of the wells associated with the former Chevron Service <br /> Station, CPL must sample the well that is either closest to the pipeline with the most shallow screen <br /> depth. By 2 September 2005, please submit a report discussing the sampling of the well, including a <br /> sampling log, the full laboratory analytical data package including chromatograms, and a thorough <br /> discussion of the total petroleum hydrocarbon sampling results as it compares to the product currently and <br /> historically pumped through the pipeline. <br /> As of today, I will no longer be the project manager for this site. Until a new project manager is assigned, <br /> correspondence and inquiries should be directed to Mr. Duncan Austin,who may be contacted at <br /> (916) 464-4712 or daustin@waterboards.ca.gov. <br /> DEVRA LEWIS <br /> Environmental Scientist <br /> cc: Mr. Harlen Knoll, San Joaquin County Public Health Services, Stockton <br /> Mr. Criseldo Mina, City of Tracy, Dept of Development and Engineering Services, Tracy <br /> Ms. Diane Russell, ChevronTexaco Pipeline Company, Law Department, Houston, TX <br /> Mr. Tom Brenkwitz,Tracy <br /> Mr. David Evans, SECOR International Incorporated, Sacramento <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br />
