2.1.1 Narrative
The GC continues excavating contaminated sediments and bank soils and restoring excavated grids in BRSA 1. Contaminated material is being loaded out from the staging pad for transport & disposal at an EPA approved landfill facility.
2.1.2 Response Actions to Date
The following activities took place during the reporting period:
- Excavation of contaminated soils with confirmation sampling results received from grids 31-36, 38, 47-48, and 53-58 (see table below for results). Grids not included in this sequence were either still awaiting analytical results from the laboratory or required additional excavation to meet cleanup objectives. A total of 43 grids have now been excavated. There are 58 grids in BRSA 1. The target clean-up goal in the riverbank soils is 5 mg/kg total PCBs.

- Reconstruction / restoration of excavated grids in BRSA 1 (see attached photo);
- Transport/disposal of approximately 1,402 tons of excavated soils to an EPA approved landfill facility. A total of 2,943 tons of excavated soils have been transported from BRSA 1 for disposal to date;
- Treatment of contact water from contaminated grids and the contaminated soils staging pad in the on site WWTP. Approximately 56,292 gallons were treated during the reporting period. A total of approximately 219,000 gallons have been treated since the start of the project. Sampling results continue to confirm non-detect levels for total PCBs in treated water;
- Daily particulate monitoring (PM10) around the perimeter of BRSA 1 with no detections off site of particulates above the action level of 1.5 mg/m3; and
- Turbidity control measures and monitoring in Kalamazoo River around the BRSA 1 (1 upstream monitor and 2 downstream monitors) with no sustained exceedances of the action level of 50 NTUs above upstream levels.

2.2.1 Anticipated Activities
During the next reporting period, the following activities are expected to occur:
- Excavation of contaminated sediments and bank soils in remaining grids of BRSA 1, including TSCA material (soils > 50 mg/kg total PCBs) from grid 29;
- Reconstruction & restoration of excavated grids in BRSA 1;
- Solidification/staging/transport of contaminated sediments & bank soils for disposal;
- Treatment of contact water in the on site WWTP;
- Operation of dust and turbidity control/monitoring systems; and
- Maintenance/monitoring of the temporary WCS.
2.2.1.1 Planned Response Activities
See Sections 2.2.1 & 2.2.1.2.
2.2.1.2 Next Steps
- A draft Technical Memorandum outlining the approach for BRSAs 2 & 3 was submitted on October 21. EPA is currently coordinating review of the document with state, federal and local partners.
