Box 4848 <br /> Anaheim, California 92803 <br /> Attention: Mr. Chuck Kolesar <br /> Dear Chuck: <br /> Schedule for Implementation of Plume Characterization Work <br /> and Proposed Location of Deep Monitoring Well <br /> Shell Oil Distribution Plant <br /> Stockton, California <br /> In response to Regional Water Quality Control Board requests, Harding Lawson Associates(HLA) <br /> has prepared this schedule for implementation of the offsite plume characterization hydropunch and <br /> well installation program at the Shell Oil Company Distribution Facility, 3515 Navy Drive, Rough and <br /> Ready Island, Stockton, California. As described in the Plume Characterization Work Plan(IILA, <br /> 1992), the proposed scope of work involves collection of 12 to 15 offsite hydropunch groundwater <br /> samples followed by installation of up to 4 offsite monitoring wells. We are tentatively scheduled to <br /> begin the hydropunch work during the week of February 22, 1993. In addition, a deep groundwater <br /> monitoring well(DW-1)will be installed onsite, near new shallow groundwater extraction well MW-24 <br /> (Plate 1). It is anticipated that the hydropunch and monitoring well installation program will take <br /> approximately 2 to 3 work weeks. Following installation, the wells will be developed and sampled <br /> during March or April 1993. After receipt of the analytical well sample results, a short letter report <br /> will be prepared documenting the collection and analysis of the hydropunch samples and installation <br /> and sampling of the new wells. <br /> Please call me at(415) 899-7367 if you have any questions. <br /> Very Truly Yours, <br /> HARDING LAAWSON ASSOCIATES <br /> Daniraig <br /> Senior Hydrogeologlst <br /> djc/plmached <br /> Attachment: Plate 1 -Locations of Proposed Groundwater Monitoring Wells and Hydropunch <br /> Samples <br /> Reference Cited: HLA, 1992.
