Attending the meeting were you representing Shell Oil,Joe Neely,Dan <br /> Lescure, and Mike Murphy representing Conestoga-Rovers &Associates (CRA),Margaret Lagorio, <br /> Nuel Henderson,Harlin Knoll,Michael Infurna,Lori Duncan,and Vicki McCartney representing <br /> EHD. There was a general discussion about total delineation of contamination for all constituents <br /> of concern at sites as well as early evaluation of all the environmental risks from the contamination <br /> such as vapor intrusion,gross contamination and direct exposure. The following is a synopsis of the <br /> status and/or site specific discussions at the meeting. <br /> 1313 Charter Way,Stockton <br /> EHD staff is not being informed of quarterly monitoring events. The extent of the 1,2 DCA <br /> contamination must be investigated on the south side of Charter Way. EHD will provide a site <br /> specific letter regarding this requirement. <br /> 620 Charter Way, Stockton <br /> CRA received an access agreement from McDonald's restaurant located at 611 West Charter Way <br /> and Shell Oil is reviewing it. CRA will attempt again to contact the property owners of the Delta <br /> Market building located at 549 West Charter Way and NDA Enterprises LLC located at 550 West <br /> Charter Way to request access to both properties for the purpose of installing monitoring wells. <br /> CRA will notify EHD if CRA believes EHD should send another letter to the two property owners. <br /> CRA will need another extension for completing the fieldwork at these two parcels. Fieldwork is <br /> scheduled for the week of May 7t� for installing monitoring wells onsite. <br /> 440 Charter Way, Stockton <br /> Shell is waiting for access agreements from off-site property owners so they can implement the <br /> approved work plan. <br /> 1267 Country Club, Stockton <br /> The core area of contamination must be laterally and vertically defined. It was discussed that a work <br /> plan would be submitted for one C-zone well on site, one C-zone well off site, one A-zone well in <br /> the core area, three B-zone wells on site and two B-zone wells off site. <br /> 2575 Country Club, Stockton <br /> The ground water extraction (GWE) system is in operation. The property owner of nearby <br /> apartments is concerned about vapor intrusion so this issue must be addressed. <br />
