I%W <br /> 460, <br /> Karen Petryna <br /> Equiva Services,LLC <br /> Page 2 <br /> 1267 Country Club Boulevard <br /> This site may be ready for closure but there are several data gaps that will need to be completed <br /> prior to closure. Questions remain as to whether the tanks have been removediat the site or are <br /> still in place. <br /> Action item: Cambria should look at Tri-Regional Guidelines and evaluate whether all <br /> requirements for closure have been met. Additional discussion with the County will be required <br /> at this site. <br /> 2494 E Fremont <br /> This site is progressing satisfactorily. There is some question regarding the apparent changing <br /> direction of groundwater flow that may be related to other sources. The results of the <br /> investigation completed in June 2001 need to be submitted to the County. <br /> 3011 Beniamin Holt Drive <br /> A preliminary assessment report(PAR) and an accompanying schedule of work need to be <br /> submitted for this site. The lateral extent of contamination has not been defined to the west and <br /> south. The County agreed to the request from Equiva and Cambria to discontinue sampling <br /> monitoring wells MW-1 and MW-2 for total petroleum hydrocarbons as diesel(TPHd). In the <br /> future, only monitoring well MW-3 will be analyzed for TPHd. <br /> 2575 Country Club Boulevard <br /> A PAR, a feasibility study, and a deep groundwater investigation need to be completed for this <br /> site. It is possible that the source of the MtBE plume is not the Shell station,but evidence <br /> supporting this has not been submitted to the County. Additionally,Ms.Petryna stated that <br /> Cambria is currently analyzing cross-gradient domestic well water samples on a quarterly basis. <br /> She said that Equiva would like to have Cambria collect samples from the domestic wells on an <br /> annual basis and analyze for MtBE only. Mike Infurna provisionally agreed with this strategy <br /> and said that he would evaluate the data and provide a final conclusion. <br /> Action item: Mike Infurna will verbally provide final agreement/disagreement with new <br /> monitoring strategy after he has evaluated the data. <br /> 7190 Lower Sacramento Road <br /> The lateral and vertical extent of contamination in the area around the USTs seems to be defined <br /> but earlier work around the dispenser island resulted in a grab groundwater sample with 110,000 <br /> µg/]TPH. The groundwater sample may be from a perched water table,but evidence supporting <br /> this has not been submitted to the County. The lateral and vertical extent of the contamination <br /> associated with the dispenser island needs to be defined. <br /> Action item: Cambria to submit a workplan to define the vertical and lateral extent of <br /> groundwater contamination in the area of the dispenser island. <br /> 6131 Pacific <br /> There was a general discussion over the access agreement issues. There was apparently some <br /> confusion on the part of Liz Franco (property management company)as to the validity of the <br /> access agreement. Liz Franco told Cambria that she understood from the County that the access <br /> agreement is not valid. The County stated that they are not in a position to say whether an <br />
