Lori Duncan, Nuel Henderson, Vicki <br /> McCartney, Harlin Knoll and I represented EHD. Kerry Wasson, Ellen Aquaro and you <br /> represented the County as the responsible party for the contaminated sites with the <br /> exception of the Airport facility that Barry Rondinella represented. <br /> It was discussed that a limited amount of money has been allocated by the County for <br /> the current fiscal year 2005-2006 for investigation and remediation of these sites and <br /> that budget preparation for the fiscal year 2006-2007 would be starting soon. In <br /> addition, EHD informed you that the Federal government wants sites contaminated from <br /> UST releases to perform the corrective actions necessary to achieve closure, so the <br /> State government is informing the local governments that they are to take the necessary <br /> actions to get the contaminated UST release sites to closure. In light of this it was <br /> discussed that some of the allocated funds should be used on the low priority sites to get <br /> them to closure. It was also discussed that the State Water Resources Control Board <br /> Cleanup Fund is not expected to be extended past the December 31, 2010 expiration <br /> date so expediting investigation and corrective action may be in the county's best <br /> interest. The county should discuss with their consultant the reduction of sampling at <br /> some sites so that completion of investigative work and sampling at other sites thought <br /> to be closer to achieving closure can occur for the remaining 2005-2006 budgeted <br /> monies. The county should also discuss with their consultant the amount of money <br /> required to complete site investigations and to perform any active remediation required <br /> during fiscal year 2006-2007 at the sites for budgeting purposes. <br /> The following is a summary of the site discussions. <br /> 1810 E. HAZELTON, STOCKTON <br /> Soil and groundwater contamination by MTBE as well as by petroleum hydrocarbon <br /> contaminants has been confirmed at this site. Currently, seven monitoring wells have <br /> been installed on-site. The lateral extent of the shallow groundwater contamination is <br /> basically defined, but the vertical extent has not been investigated. Air sparge and vapor <br /> extraction wells have been installed and feasibility tests are to be conducted. Cross <br />
