Pagel of 2 <br /> Vicki McCartney [EH] <br /> From: Vicki McCartney [EH] <br /> Sent: Wednesday, May 19, 2010 4:09 PM <br /> To: 'Tom Ballard' <br /> Cc: Nuel Henderson [EH] <br /> Subject: RE: California Tank Line site <br /> Tom, <br /> I don't see anything mentioned in your email about defining the lateral extent of the groundwater plume around <br /> MW-4. This must be addressed in the work plan. <br /> I will be on vacation beginning May 24th. You may contact Nuel Henderson, if necessary, while I am away. <br /> Nuel's number is 209.468.3436. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton,California 95202 <br /> Phone: (209)468-9852 <br /> Fax: (209)468-3433 <br /> Email: vmccartnevld!sicehd.com <br /> From: Tom Ballard [mailto:TBaIla rd@taberconsultants.com] <br /> Sent: Wednesday, May 19, 2010 2:47 PM <br /> To: Vicki McCartney [EH] <br /> Cc: Martin Wills <br /> Subject: RE: California Tank Line site <br /> Vicki.- <br /> Sorry <br /> icki:Sorry for the delay, but here is the update: <br /> 1.) Sensitive Receptor Survey —we are in the field today following up on and confirming some well <br /> locations. The report is pretty much done so I anticipate having that to you by the end of the week <br /> or early next week. <br /> 2.) Report Revisions—we had some challenges with all the historical soil sampling data, but I think we <br /> have all that handled now. The revised reports are in final review and should be uploaded to <br /> Geotracker by the beginning of next week. <br /> 3.) Work Plan — Guy Roy is doing the bulk of the work on this and he should have the draft to me for <br /> my review by the end of the week, hopefully. The work plan will include information on installing <br /> the adsorbent material in MW-2 and will address the update to the Human Health Risk <br /> Assessment using the new DTSC petroleum hydrocarbon fractionation guidelines and the Natural <br /> Attenuation Assessment to address the area around MW-4. Also, there is some question on <br /> whether MW-1 is actually silted in, as had been discussed in our meeting, and that will be <br /> addressed in the work plan, as well. <br /> believe that addresses everything, but if I have missed anything, please let me know. <br /> Thomas E.
