(Condor) <br /> on behalf of Herman &Helen's Marina at the Venice Island Ferry in Stockton (site). The site is a <br /> parking area with three gasoline aboveground tanks (AGT) on a concrete pad east of Little Connection <br /> Slough and its associated levee. Based on a hole in one of five underground storage tanks removed in <br /> October 1991, investigation and cleanup at the site was originally under the oversight of the San Joaquin <br /> County Public Services/Environmental Health Department (PS/EHD), Reclamation District#2029, and <br /> the Board's Underground Storage Tank unit. Board staff and PS/EHD have since determined that the <br /> cause of the contamination is the AGTs and the site is now under the oversight of the Board's AGT Unit. <br /> The Investigation Report discusses 13 borings advanced during the September 2000 investigation and <br /> results of associated soil and groundwater sampling. The Quarterly Report discusses the results of the <br /> 13 December 2000 groundwater sampling. We have the following comments on these reports: <br /> 1. The Investigation Report does not include the number, size, contents, or operations status of the <br /> AGTs present on the site. Herman &Helen's Marina should provide this information in <br /> subsequent reports. <br /> 2. The Investigation Report includes a sensitive receptor survey, but does not include a map with <br /> locations of the two water wells identified in relation to the site. Herman &Helen's Marina must <br /> provide a map in the work plan for additional investigation (see below) to show the location of <br /> these two water wells with respect to the site. <br /> 3. The Investigation Report states"only trace concentrations of MTBE [methyl tertiary butyl ether] <br /> are present in groundwater from the deeper soil strata." The only deep groundwater samples <br /> were collected approximately 150 feet from the source area and on the east side of the drainage <br /> ditch. Herman&Helen's Marina must delineate the vertical extent of MTBE near the source <br /> area. <br /> California Environmental Protection Agency <br /> Recycled Paper <br /> The energy challenge facing California is real.
