Box 5155 <br /> San Ramon, California 94583 <br /> Attention: Mr. Robert A. Boust <br /> RE: Case Closure Report <br /> Former Unocal Bulk Plant #0950 <br /> 2835 Navy Drive <br /> Stockton, California <br /> Dear Mr. Boust: <br /> INTRODUCTION <br /> This report presents a comprehensive summary of all of the soil <br /> sampling, ground water monitoring and sampling, and soil remedia- <br /> tion activities that were conducted by Kaprealian Engineering, Inc. <br /> • (KEI) at the referenced site from April 1992 through May 1993 . <br /> This report also presents a brief and partial summary of some of <br /> the site assessment work conducted by other consultants prior to <br /> KEI ' s involvement at this former Unocal facility. This report was <br /> prepared in accordance with Tri-Regional Board Staff Recommenda- <br /> tions for Preliminary Investigation and Evaluation of Underground <br /> Tank Sites - Request for Closure (Appendix B) guidance document. <br /> The Central Valley Regional Water Quality Control Board' s (RWQCB) <br /> "Case Closure Checklist" has also been completed and is attached to <br /> this report. Based on the analytical results of all of the soil <br /> and ground water samples collected and evaluated to date, it is <br /> KEI ' s opinion that no further ground water monitoring and sampling <br /> is warranted at the Unocal site, unless required by regulatory <br /> agencies. <br /> SITE DESCRIPTION AND BACKGROUND <br /> The subject site was formerly used as a bulk petroleum product <br /> marketing station.
