1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

2.1.1 Narrative
Excavation of contaminated riverbank soils and in-stream sediments along with restoration are near completion in BRSA 4. The staging area is constructed and removal operations began in BRSA 6.

2.1.2 Response Actions During Reporting Period

BRSA 4 & 5
- Excavation of contaminated soils continues with excavation completed and confirmation results received in riverbank grids 39-43 and 47-51 (grids 44-46 are yet to be excavated). Due to field adjustments, there are now 51 total grids in BRSA 4, with each grid consisting of approximately 50 lineal feet of riverbank. The target clean-up goal in the riverbank soils is 5 mg/kg total PCBs;
- Completed removal of sheet piling in first 'stream tube'; and
- Completed excavation of contaminated in-stream sediments in the second 'stream tube' in BRSA 4, which is located within the river channel immediately adjacent to riverbank grids 47-50. The target clean-up goal for in-stream sediments is 1 mg/kg total PCBs.
- Due to field adjustments, in-stream sediments were excavated from a single stream tube in BRSA 5.

Estimated excavation depths and confirmation sampling results are found in the table below for riverbank grids (Table 1), 'stream tube' grids (Table 2), and a 'stream tube' grid in BRSA 5 (Table 3):

BRSA 6
- Excavation of contaminated riverbank soils and in-stream sediments;
- Installation of sand bag and sheet pile coffer dam systems;
- Apply treatment to control invasive plants;
- Treat contact water from contaminated grids and contaminated soils staging pad; and
- Transport contaminated soils and sediments for disposal.

BRSA 9
- Commence construction of staging area;
- Apply treatment to control invasive plants; and
- Begin transport of equipment, supplies and materials to staging area.

SITEWIDE
- Operate dust and turbidity control/monitoring systems; and
- Maintain/monitor temporary WCS.
