Removal Action Activities continue during the week of 5/7/07 through 5/11/07. Local weather has not been a factor during the week's activities. ERRS and their sub UXO contractor, USA Environmental Inc, continued/completed Grid clearance activities in Grids C4c, K4d, C3d, I4c, and C3a. USA continues to utilize a two team approach to Phase 1 activities as per Work Plan.
A QC inspection was done on 5/8/07 to assess Grid C4c. EPA performed a QA inspection on Grid C4c to ensure that the Grid has been cleared as per the FOSCs discretion. The grid was deemed ‘passed’ on 5/8/07.
A QC inspection was completed on C3d on 5/10/07. EPA performed a QA inspection on Grid C3d on 5/10/07. The grid was deemed ‘passed’ on 5/10/07 as per the FOSCs discretion.
Team #2 completed a 5.5 day sweep of Grid K4d on 5/9/07. In the southern portion of the Grid, an area with a high concentration of anomalies was identified. Considerable excavation was conducted and no significant anomalies were uncovered. It appears that soils containing conductive or magnetic components were present in the Grid (‘Mineralized Ground’). EPA performed a QA of the Grid on 5/11/07 and passed the grid.
Team #1 completed sweep of C3b on 5/11/07 and QC commenced on the Grid at 1530. Daily morning Safety Meetings and Tailgate Meetings continue with site personnel as per the WP. Daily activities include clearing of metal anomalies within 1.5ft bgs.
Both teams will continue/begin mag and dig activities in Grids I4c and B3b, as per the FOSCs direction. EPA conducted its weekly operations meeting in the late afternoon of 5/10/07 with GES, USA, RMC and TTNUS to discuss productivity, QA/QC and health and safety.
The following items have been recovered from 5/7/07 through 5/11/07:
MEC Items = 125 No. of Digs = 3217 MD in lbs. = 50.85 Lbs. of Scrap = 50.6 Lbs. of Hot Rocks = 101
Two SOPs were finalized by EPA/START/GES: a. QA final clearance SOP b. Mineralized Ground assessment and clearance
