Subject: RE: Barnes Trucking Facility Hydrogen Peroxide injection <br /> II As you have seen from the feedback from the pipeline representatives , they are very <br /> concerned about the chemicals not reaching their pipes . <br /> During the process of writing the MRP , it became apparent that we had not planned for each <br /> i. of the required monitoring wells to comply with their injection permit requ] rements . <br /> Thus , the additional wells for observation . In addition , the three wells at the property <br /> line can be used for extraction in the event that the sensors in those wells detect any <br /> chemicals moving off the property . <br /> Especially in light of the San Bruno disaster , I think we can predict that the pipeline <br /> companies are going to be extremely defensive about their pipeline integrity . <br /> j They are screened from the deepest that we are injecting , to the top of groundwater with <br /> the intent to detect any of the injection chemicals right away from any of the impacted <br /> zones . Since the objective is to clean up the site and then abandon them , in the near <br /> term , their serving as a conduit , the end result should be considered a maximum benefit in <br /> comparison to the possibility that they will act as conduits during the injection period , <br /> which we don ' t foresee lasting more than 3 months , at the maximum . <br /> I hope this answers all of your concerns . <br /> Olivia <br /> - - - - -Original Message - - - - - <br /> From : Lori Duncan [EH] [mailto : lduncan@slcehd . com] <br /> Sent : Thursday , October 28 , 2010 4 : 21 PM <br /> TO : Olivia Jacobs <br /> y Cc : Nuel Henderson [EH] <br /> 9 Subject : RE : Barnes Trucking Facility Hydrogen Peroxide injection <br /> Olivia , <br /> Why are there five additional groundwater monitoring wells on the maps in this document ? <br /> Only one additional well was mentioned in the RAP , and no technical justification was <br /> provided for it , much less five . Did the Regional Board request them? <br /> I understand they are proposed to be five feet deeper than the existing wells , but they <br /> are right next to and have overlapping screen intervals of from 15 - 20 with the existing <br /> wells . What information is it you expect them to provide ? <br /> Lori Duncan , Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> lduncan@sjcehd . com <br /> ( 209 ) 468 - 0337 phone <br /> ( 209 ) 468 - 3433 fax <br /> - - - - -Original Message - - - - - <br /> From : Olivia Jacobs [mailto : OJacobs@clearwatergroup . com] <br /> Sent : Wednesday , October 27 , 2010 10 : 22 AM <br /> To : Jim Barton ; Steve Cooper ; Ken Yeo ; Adrienne Ellsaesser [EH] ; Lori Duncan [ EHI ; Nuel <br /> Henderson [EH] <br /> Cc : James Eggenberger ; Jared DeVore ; Kelly Johnson ; Steve Osborn ; Steve Marositz <br /> Subject : RE : Barnes Trucking Facility Hydrogen Peroxide injection <br /> 1 <br />
