You were directed to submit a work <br /> plan addendum by 01 May 2006 for nested or clustered wells to continue the <br /> lateral delineation of your dissolved gasoline-impacted groundwater plume. The <br /> 14 March 2006 letter also directed you to submit a preliminary evaluation of the <br /> potential for vapor intrusion of nearby buildings from your soil and/or <br /> contaminated groundwater plumes by 01 June 2006. To date, neither the work <br /> plan addendum nor the vapor intrusion evaluation has been received by the <br /> EHD. Submit both documents to the EHD by 01 August 2007. <br /> The EHD has also reviewed Aquifer Pump Test and Soil Vapor Extraction Pilot <br /> Test Report (Test Report), dated 07 February 2007, prepared by Advanced <br /> GeoEnviron mental, Inc. (AGE). In the Test Report, AGE concludes that <br /> groundwater extraction and soil vapor extraction can be successfully utilized to <br /> mitigate contaminated groundwater and vadose zone contaminated soil on your <br /> site. AGE recommends preparation of a work plan to implement groundwater <br />
