Sensitive Receptor Survey —we are in the field today following up on and confirming some well locations. <br /> The report is pretty much done so I anticipate having that to you by the end of the week or early next <br /> week. <br /> 2.) Report Revisions —we had some challenges with all the historical soil sampling data, but I think we have <br /> all that handled now. The revised reports are in final review and should be uploaded to Geotracker by the <br /> 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 my <br /> review by the end of the week, hopefully. The work plan will include information on installing the <br /> adsorbent material in MW-2 and will address the update to the Human Health Risk Assessment using the <br /> new DTSC petroleum hydrocarbon fractionation guidelines and the Natural Attenuation Assessment to <br /> address the area around MW-4. Also, there is some question on whether MW-1 is actually silted in, as <br /> had been discussed in our meeting, and that will be addressed in the work plan, as well. <br /> I believe that addresses everything, but if I have missed anything, please let me know. <br /> Thomas E.

Instead, a new work plan would be submitted by Taber to address <br /> the free product found in MW-2, and the delineation of the petroleum hydrocarbon contamination detected in <br /> groundwater collected from MW-4. It has been nearly six weeks and our department has not received a work <br /> plan. Our department also needs the sensitive receptor survey report, and the contaminant mass estimates, <br /> and reports to GeoTracker must be uploaded. Please provide me with the timeline for completing these tasks. <br /> Thank you. <br /> 5/19/2010 <br />
