James Giottonini <br /> Page 2 <br /> 22 East Market <br /> * All underground storage tanks have been removed. There is a section of underground;piping <br /> that needs to be resampled. This section will be resampled by March 15, 1994. <br /> ' A section of piping remains in place and requires proper closure. A closure plan should be <br /> submitted to PHS/EHD Unit III and the piping closed in place by March 15, 1994. <br /> ' The report discussing the last phase of the investigation is currently being compiled by <br /> RESNA and will be submitted by March 1, 1994. The report will give an estimate of the <br /> residual hydrocarbons remaining beneath the building. <br /> * The last groundwater sampling occurred on September 6, 1993. The sampling frequency is <br /> semi-annual for this site. The sampling of the monitoring well will also be addressed in the <br /> report. <br /> Argonne and Picardy <br /> * The City of Stockton has issued a purchase order for the proposed over-excavation of the <br /> former tank pit. The workplan proposes an additional 5' of soil to be removed and at least <br /> four sidewall samples and one bottom soil sample to be collected to confirm hydrocarbon <br /> removal. The new contractor,Falcon Energy,needs to submit a site specific health and safety <br /> plan before the work can be scheduled. The health and safety plan will be submitted within <br /> 2 weeks or another contractor may be selected. <br /> * The work will be completed and the documentation of the work (to include the laboratory <br /> results, chain of custody, and the soil disposal records) will be submitted to PHS/EHD for <br /> evaluation by May 1, 1994. <br /> ' Should the limited excavation attempt fail to remove the remaining hydrocarbons, any <br /> additional work at this site should be conducted under the guidance of a qualified <br /> professional. <br /> The next meeting is scheduled for Tuesday, May 3, 1994 at 1:30 p.m. and will be held at the PHS/EHD office. <br /> Should you have any questions or disagree with this summary of the February 7, 1994 meeting, please contact <br /> Mary Meays at (209) 468-0337 or Linda Turkatte at (209) 468-3441 of my staff. <br /> Ernest M.
