Box 2009 <br />Stockton, CA 95201 <br />Subject: Disposal Profiling of Soil from Former Chevron Station #9-5775 West Kettlernan Lane, Lodi, CA. <br />Mr. Knoll: <br />Prime Shine will excavate approximately 450 cubic yards (yd') of soil from the proposed service bay, approximately <br />315 yd' from the reverse osmosis tank pit, and approximately 90 yd' from the car wash reclamation pit (Figure 3). They <br />will be loading this soil from the excavation directly into trucks for transport to the disposal facility. To facilitate direct <br />loading, Chevron will pre -profile the soil in place. This will be accomplished by using a GeoProbe to advance borings <br />in each of the proposed excavation areas. These borings will not be logged. Soil samples from the borings will be <br />composited as required by the BFI landfill in Livermore, California. On completion the borings will be backfilled to <br />ground surface with neat cement. <br />The proposed service bay will be excavated to approximately 8 feet below ground surface (bgs). Five borings will be <br />advanced, and soil samples will be collected in each of the borings�at 2 feet, 4 feet, 6 feet, and 8 feet bgs. Four borings <br />will be advanced to 13 feet bgs in the proposed reverse osmosis tank pit. Soil samples will be collected a 2 feet, 5 feet, <br />10 feet, and 13 feet bgs. The four samples collected in each of these borings will be composited into one sample. Two <br />borings will be advanced in the proposed car wash reclamation pit to 7 feet bgs, and soil samples collected at 4 and 7 <br />feet bgs. These four soil samples will be composited into one. <br />Ten composite soil samples will be submitted to Sequoia Analytical (ELAP #1271) for analysis. The samples will be <br />analzyed for TPHg, BTEX, MtBE, and total lead. If the soil is not impacted, disposal of the excavated soil will be the <br />responsibility of Prime Shine. If impacted, soil will be transported to BFI for disposal. BFI will require the two samples <br />with the highest TPHg concentrations also be analyzed for halogenated volatile organics. <br />GeoProbe activities will be performed by Fisch Environmental (C57 #683865). An application to perform this work <br />is attached, along with a check to cover the application fee. We are scheduled to perform this work on April 13, 2000. <br />Your expedited review of this attached permit wo�cciated.
