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: C3, B3, G5d, and A4 and Taz anomalies 1, and 2. See map for reference to Taz anomaly areas: https://www.epaosc.net/sites/1299/files/taz_areas1.pdf
Final QA/QC clearance was determined for grids G6a and F6a.
On August 3 the TAZ was demobilized. The subcontractor and prime (Timberline and IPC respectively) determined that the TAZ had been on site long enough. The FOSC was never notified of this decision. The TAZ was demobilized thru adjacent private properties with some minor damages to those properties. The FOSC views the Taz as being marginally successful during its stay on site. The Taz routinely got bogged down in wet soils, its screen size was too large allowing small items to pass thru and ultimately sifted only 25% of its contracted volume.
On August 8, the USACE informed IPC that the new site demobe date is September 9 due to enough funding being available. The USACE notified the FOSC on August 15 that as many as four IPC personnel (half the team) would be demobing on August 24 due to having found other employment, as a result of the initial declared demobe date of August 24. Therefore IPC will be operating with a smaller team starting August 24.
During this reporting period validated analytical data from the June 12 soil sampling event of the pit spoils was returned. Of noteworthy the grab sample representing the slag layer returned a value of 9.57mg/l for TCLP lead analysis.
Demolition shots of MPPEH were conducted on August 1, 9 and 16. Pre and post soil samples were retrieved by START on August 9 as per SAP. The following MPPEH were rendered safe during these shots:
(700) 6" Burster Tubes
(30) 14oz Boosters (DONOR CHRG)
150' 50oz Detonating Cord (DONOR)
500' Shock Tube W/Det (DONOR)
(557) 6" Burster Tubes Bunker
(30) 14oz Orange Cap Boosters DONOR CHARGE
500' Shock Tube W/cap DONOR CHARGE
88' 50oz Det Cord DONOR CHARGE
(850) 6" Burster Tubes
52' Det. Cord donor
500' Shock Tube W/Detonator donor
(30) 14oz. Org. Cap Booster donor
IPC personnel continue to maintain the covering of the piles of the large pit piles.
The EPA FOSC continues to conduct project weekly conference calls, every Tuesday between EPA, MDE and USACE. EPA's Start contractor maintains the minutes of these discussions.
Priorities for the next reporting period are for IPC to complete as many grids/subgrids as possible focusing on open grids. These grids will be focussed on: G5d,C3a/d,B3a/b and possibly K4.
