Present at the meeting <br /> were Jeanne Homsey, ATC Associates, Inc. (ATC), Lorraine Sawyer, ATC, on speaker <br /> phone, and Lori Duncan and Nuel Henderson, SJC/EHD. <br /> The following items were discussed and/or agreed upon at the meeting: <br /> 1. An acoustical blanket has been received by ATC and will be installed on the <br /> blower of the soil vapor extraction system within the next week to reduce the <br /> noise nuisance from the system. <br /> 2. A work plan addendum for conducting a cone penetrometor test (CPT) boring <br /> investigation will be submitted to SJC/EHD by the end of the year. The CPT <br /> borings will be the next phase of work performed at the site. <br /> 3. If additional monitoring wells are needed, their locations and depths will be <br /> determined after analysis of the results of the CPT investigation, and they will <br /> be installed in a second phase of work. <br /> 4. A deeper (-130 foot) groundwater monitoring well must be installed onsite to <br /> vertically define the contamination present in well MW-6; this deep well will be <br /> installed during the second phase of work. <br /> If you have any questions please call Lori Duncan at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department <br /> Lori Duncan, Senior REHS Nuel Henderson, Jr., PG <br /> LOP/Site Mitigation Unit IV Engineering Geologist, Unit IV <br /> cc: James Barton, PG, CVRWQCB <br /> Jeanne Homsey, PE, ATC <br /> Lorraine Sawyer, PG, ATC <br />
