(ro <br /> JAMES GIOTTONINI ✓ PAGE 2 <br /> 22 East Market/Police Station <br /> PHS/EHD indicated by October 17, 1995 correspondence would be prepared to comment on the <br /> parameter information which was submitted. <br /> 134 Sutter <br /> PHS/EHD indicated that a comment letter would be prepared by October 18, 1995 requesting an <br /> alternative location for the proposed soil boring to investigate the extent of soil contamination observed <br /> at the time of over-excavation. PHS/EHD staff was subsequently informed that the site is under <br /> supervisorial review and an evaluation of the necessity for additional soil investigation will be provided. <br /> Fontana Drive at Smith Canal <br /> This site was discussed at a later date after Jim Escobar returned from vacation. He has a bid package <br /> which includes a scope of work to install a soil vent system at the site. However, it was decided that <br /> before proceeding to this step, test wells must be installed and a pilot test performed at the site. In <br /> addition, this new information must be submitted to PHS/EHD in the form of an amended CAP. Jim <br /> Escobar will look into this situation and will provide an update shortly. <br /> 110 West Sonora <br /> This site was discussed at a later date after Jim Escobar returned from vacation. The cost estimate for <br /> the permitting, construction and operation of the proposed system for this site has been received by the <br /> City. The cost proposal must be put before the city council and may have to be put out to bid. <br /> 1740 Houston Avenue <br /> The August 1995 over-excavation of the former tank pit area was discussed. The contamination first <br /> noted in the west end of the tank pit was not addressed at the over-excavation as the area was partially <br /> backfilled. The east end of the tank pit, which was originally thought to be not impacted, showed <br /> contamination at 14 feet below ground surface. The shallow depth to water at the site, and the <br /> significant volume of water produced by the excavation were discussed as obstacles to further <br /> excavation. The installation of soil borings, with push point technology if feasible, was discussed as a <br /> tool to determine the extent of the impact at the site so that an evaluation can be made as to whether <br /> further excavation or some other alternative would be the most efficient, cost effective approach for the <br /> site. <br /> Twining will be asked to summarize their work in a report, including the water results from the newest <br /> monitoring well. The next phase of work will be submitted in a work plan. Currently, the excavation <br /> is backfilled. <br /> The next meeting is scheduled for Tuesday, January 9, 1996 at 1:30 p.m. and will be held at the PHS/EHD <br /> office. <br /> Should you have any questions or disagree with this summary, please contact either Mary Meays at (209) 468- <br /> 0337, Steve Sasson at (209) 468-3459, or Linda Turkatte at (209) 468-3441. <br /> onna Heran, RE S, Director <br /> vironm"IHe Division <br /> Di a ts <br /> Supervisor <br /> MM\COS.MET <br /> cc: Elizabeth Thayer, CVRWQCB cc: Jim Escobar, COS Public Works <br /> cc: Stephen Chen, COS Public Works cc: Bob Murdoch, COS Public Works <br />
