Karna Harrigfeld indicated that she would be submitting <br /> information on the buyer's status as it becomes available. <br /> PHS/EHD indicated that confirmation soil borings would be necessary to evaluate <br /> any residual soil contamination. Shell agreed to submit within one month an <br /> addendum work plan and a permit application. The additional analyses to provide <br /> site specific environmental fate analysis., including Toxicity Characteristic Leaching <br /> Procedure (designed to determine mobile fractions) and organic carbon content <br /> would be performed. A brief discussion ensued regarding the merits and <br /> drawbacks of push point technology versus auger drilling methodology. <br /> A number of modifications to the remediation systems were agreed upon including <br /> the following: the groundwater extraction system will be turned off; the <br /> submersible pumps removed from the extraction wells; and the-City of Stockton <br /> notified. The vapor extraction system will be temporarily turned off, prior to <br /> confirmation soil sampling, so that the subsurface environment can equilibrate. <br /> Groundwater oxygenation will be initiated in the extraction wells and continued in <br /> the monitoring wells. <br /> A Division of San Joaquin County Health Care Services <br />
