Work Mission Statement:
Safely and efficiently investigate and remove Munitions and Explosives of Concern (MEC); Materials Potentially Possessing an Explosive Hazard (MPPEH), Munitions Debris (MD) and explosively contaminated soil(TNT) from the Elkton Farms Firehole Site, as defined in EPA's geophysical study.
During this reporting period the intrusive activities continued within grids: B4,E5,G6,H5 and K5,. These activities included magging and flagging of all metal items and the hand digging/shovelling of these flagged materials.
The FOSC instituted a weekly conference call with MDE and USACE. This was instituted to assist with site communications.
The Rangemaster, originally scheduled to arrive on site on April 17 will now arrive on April 24. This is due to transportation related delays. The Rangemaster will be used to remotely scrape and sift Phase II grids.
On April 10 and 11 the USACE discussed the ROE (access agreement) with the two property owners impacted by the mobe of the Rangemaster. In addition the power company was faxed a copy. It appears that all three property owners are willing to cooperate.
On April 13, a large magnetic anomaly was detected in grid B4b. The anomaly is approximately 45'x 55' in area. This anomaly was not detected in the EM-61 geophysical survey. The FOSC to discuss proper disposition with the USACE and MDE.
