Pagel of 3 Mike Infurna [EH ] From : Furgal , Stephanie [SFurgal@chevron .com] Sent: Friday, November 07 , 2008 4 :47 PM To : Evans, David ; Mike Infurna [EH] Cc: Lay, David Subject: RE : former Chevron 9-4054 My apologies for chiming in so late in the game , I 've been in meetings all day. I don 't see a problem adding the analyses to the current protocol for one quarter and then re-evaluating for continued use once we have the results . Stephanie A. Furgal Project Manager - Marketing Business Unit From : Mike Infurna [EH ] [mailto : MInfurna@sjcehd .com] Sent: Friday, November 07, 2008 2 : 02 PM To : Evans, David Subject: RE : former Chevron 9-4054 thanks for the response and inclusion . . . Whether your choice or Stephanie's , I appreciate the cooperation . let's get this QTR data and see what happens . . . . If TAME and DCA aren 't present , I see no reason for Chevron to include them quarterly for all wells . . . . . Maybe once in a while sample the existing wells , wells that show hits , and sample ALL new wells/borings for it . . . . TAME is showing up in the 40'-50' interval in Blvd 's monitoring wells north of the site on Elmwood and on Franklin . With Stephanie asking about/pursuing "Co-mingle" concerns , I 'm curious why a typically Chevron additive is showing up on Elmwood , WEST of Franklin ?? ? ? ? by the way . . . any chance the pending MW-9 and MW- 12 , AND MW-4D well installations can get these CDCs sampled for in selected soil samples ? could go a long way in supporting source conclusions later on . . , thanks again for the cooperation . 9 From : Evans, David [mai Ito : David .
