1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

2.1.1 Narrative
Excavation of contaminated riverbank soils and in-stream sediments is complete in BRSA 4. Removal operations continue in BRSA 6. The staging area is nearly completed in BRSA 9.

2.1.2 Response Actions During Reporting Period

BRSA 4
- Excavation of contaminated soils and sediments was completed, with confirmation results received, in both riverbank grids 44-46 and the adjacent stream tube grids (see Tables 1 & 2);
- Completed transportation and disposal of contaminated soils and sediments for disposal;
- Demobilization of the WWTP, office trailer, equipment and supplies; and
- Backfilling, grading, stabilization and restoration of river banks continues.

BRSA 6
- Excavation of contaminated soils continues with excavation completed and confirmation results received in riverbank grids 6-8. There are 54 total grids in BRSA 6, with each grid consisting of approximately 50 lineal feet of riverbank. There are 4 stream tubes, with each stream tube varying in size. The target clean-up goal in the riverbank soils is 5 mg/kg total PCBs and in-stream sediments is 1mg/kg total PCBs; and
- Completed construction of sheet pile coffer dam systems to facilitate removal of riverbank soils and in-stream sediments.

Estimated excavation depths and confirmation sampling results are found below for riverbank grids in BRSA 4 (Table 1) and adjacent stream tube grids (Table 2) along with results from BRSA 6 (Table 3) and adjacent stream tube grids (Table 4).
