Dave/Riaz, NMED/EPA have reviewed the proposed plan of action for the removal of soil exceeding the soil remediation goals and have the following requests and comments.1. Attached is a markup of the map which Riaz sent. Please verify that the identified locations are correct. In the future, please provide figures showing locations of interest. In addition, this figure does
not show the confirmation samples taken in May 2007 around areas represented by SB-44, SB-47, SB-45, SB48, and SB-54. Please include these sample locations and include the SRG values for Zinc (200mg/kg) and BAP (7.8 mg/kg).

2. Please indicate that the soils will be staged on the southern portion of the site property and will be stabilized and disposed in the WWR area during remedial action.

3. Please provide a proposed schedule of activity as well as an

assurance that this will not delay or affect the upper intermediate aquifer characterization activity. Please include field schedule and report submittal schedule.

4. Sampling of the CS-10 locations will be grab or composite? Will be taken at what depth?

5. What is 'HNU type instrument'?

6. During excavation please make efforts to GPS sample locations and extent of soil removal (horizontal and lateral) so that these activities can be documented in the final report and shown accurately on maps.

7. For future reference, please provide the actual acreage, legal description, and land parcel map for GCC. My understanding is that this is a 16 acre parcel rather than a 20 acre parcel.

cc "Ahmed, Riaz \(Houston,TX-US\)" <RAhmed@TRCSOLUTIONS.com> Subject Sampling at GCC PropertyHere is the proposed plan of action to remove additional impacted soils from GCC area. If you all agree with the proposed plan, we would like to accomplish first task ASAP, even before we mobilize on August 20.

BNSF is in the process of selling a 20 acre L shaped parcel north of the fence to GCC Premium Transloaders (GCC). At locations, GCC observed several north-south linear surface expression of asphaltic like material. GCC requested that BNSF remove this material. The removal of this material was completed soon after. During this removal process , BNSF noted that certain areas seemed impacted based on visual and odor observations. The impacted soil was also removed at the same time. Upon removal of all material, 10 composite sample were taken to verify that the bottom of the excavation met soil remediation goals(SRG). The attached figure shows areas of excavation and composite samples taken for verification

purposes.Verification sampling showed three samples to exceed SRG. They are CSG04 with Zinc at 372mg/kg, CS-G06 with BAP at 26.8 and CS-G10 with zinc at 215. As evident from the attached figure, CS-G04 and CS-G06 are not composite samples. CS-G10 is a composite of three samples.

First task will be to sample CS-G10-1, CS-G10-2, and CS-G10-3 for zinc and identify location(s) that have zinc above 200 mg/kg.

Second task will be to step out 10 feet ( can be adjusted in field based on visual or odor observations) in all four direction . Excavate the entire area i.e. 20 ft by 20 ft to a depth of three feet. A soil sample will be taken at the center of each wall and analyzed for BAP in case of CS-G06 and zinc for others. Step out will be continued till we obtain data that shows soil samples to be blow SRG.

Since these areas have already been excavated to a certain extent, the following procedure will be used to determine the depth of excavation:1- Around each excavation at least three elevation measurements will made

on undisturbed land.2- The average of the three measurements will be used

as reference elevation for that location.3- Reference elevation minus three feet will be used as the target elevation of excavation at that particularlocation.

All work will be done as per Site Health and Safety plan and a HNU type instrument will be available at the site.

Katrina: The following are NMED comments on the proposed plan of action for the GCC property that was submitted today by Riaz Ahmed.

____________________________________ Attached is a markup of the map which Riaz sent. I would ask that BNSF verify that I have identified the locations correctly. In the future,

I would appreciate if BNSF could provide such visual aids in its submittals.

Second, for those of us who are still trying to catch up with the Site history, please request that BNSF confirm that the SRG numerical values are still as documented in the ROD, section 9.2, i.e., Zn 200 mg/kg BAP 7.8 mg/kg NMED would also appreciate if future workplan submittals also include such values, and reference their origins, when appropriate.

Third, please request BNSF provide a proposed schedule for the conduct of the activities under this workplan.

Fourth, please request BNSF to provide assurance that the conduct of these activities will not affect the proposed upper intermediate aquifer characterization program that is scheduled to begin on 8/20/2007.

Please let me know if you have any concerns or questions about this.
