(GR)has prepared this Addendum to our <br /> Work Plan For Soil Sampling Following Product Piping Removal, dated August 21, 1998(work plan). In addition <br /> to upgrading the existing product piping,as outlined in the referenced work plan, Tosco will also remove and replace <br /> the existing gasoline underground storage tanks(USTs)at the site. <br /> In addition to proposed sampling outlined in the work plan, GR will observe the removal of the USTs and collect <br /> compliance samples from the UST excavation in accordance with San Joaquin County Public Health Services <br /> (SJCPHS)guidelines. UST locations are shown on Figure 2 of the work plan. Based on water levels in monitoring <br /> wells at the site,GR anticipates encountering groundwater in the UST pit and will collect a groundwater sample and <br /> compliance soil samples from the sidewalls above groundwater. Soil and groundwater samples will be collected, <br /> handled, and analyzed using the methods outlined in the work plan. <br /> If either subjective field evidence or analytical data indicate soil beneath the site has been impacted by hydrocarbons, <br /> Tosco may elect to excavate the impacted soil. GR will observe the excavation activities. Confirmation samples will <br /> be collected from the lateral limits of the excavation and analyses performed in accordance with SJCPHS guidelines. <br /> Excavated soil and backfill material will be stockpiled at the site pending characterization and disposal per the methods <br /> outlined in the work plan. <br /> Upon completion of all environmental activities associated with the UST and product piping removal, and receipt of <br /> all data, GR will prepare a report documenting the sampling activities and analytical results. This report will be <br /> prepared for Tosco's use and distribution. <br /> If you have any questions regarding this work plan addendum, please do not hesitate to call me at(925)551-7555. <br /> Sincerely, <br /> Gettler-Ryan,Inc. <br /> Douglas J.
