2.1.1 Narrative
Dredging operations in Axtell Creek were completed on August 13 and backfilling was completed on August 17. Elevated PCB test results at target excavation depths (see Sections 2.1.2, 2.2 and 2.2.2) required two over-excavations to meet the clean-up performance standard. Crews completed preparations in SA5D and SA5C (Upjohn Park) to begin excavation of contaminated sediments on August 20. Remaining excavated sediments from Axtell Creek were further solidified on the staging pad and shipped for disposal at designated landfills.
2.1.2 Response Actions to Date
From August 4 to August 17, EPA, START and ERRS contractors/sub-contractors conducted the following activities:
Site Activities - Axtell Creek
- Completed second over-excavation and backfilling of creek channel and banks;
- Complete final confirmatory sampling at second over-excavation bottom in grids AXC-1 to AXC-5 to determine if cleanup goals were met. Final sampling results from all 5 grids met the performance standard of 10 mg/kg PCBs. Confirmatory sample results from grids AXC-1, AXC-2, AXC-4 and AXC-5 met the performance standard goal of 1 mg/kg PCBs (see table);

- Completed construction of a 12" pipeline to support bypass pumps at John Street and discharge at Vine Street;
- Pumped and treated contaminated contact water in EPA's mobile wastewater treatment system; and
- Conducted stream turbidity and particulate monitoring in work areas with all results below action levels.
Site Activities - Staging Pad
- Solidified and loaded out 447.53 tons of TSCA (> 50ppm PCBs) contaminated sediments for disposal at Wayne Disposal landfill in Belleville, Michigan;
- Solidified and loaded out 631.17 tons of non-TSCA (< 50ppm PCBs) contaminated sediments for disposal at C&C Landfill in Marshall, Michigan; and
- Treated 65,369 gallons of contaminated contact water in EPA's mobile wastewater treatment plant, with a total of 445,501 gallons treated to date.
Site Activities - SA6
- Installed new fencing on the west bank which had been removed to facilitate contaminated sediment removal;
- Completed temporary grass seeding and straw placement on east and west banks;
- Replaced gravel on east bank properties impacted by the 30" discharge pipeline; and
- Repaired or replaced asphalt pavement on adjacent parking lots used to access area.
Site Activities - SA5D & SA5C
- Constructed sand-bag coffer dam to facilitate groundwater de-watering between Lake Street and the Upjohn Park footbridge;
- Constructed a wood platform working deck on east bank to support contaminated sediment removal and transport operations; and
- Installed groundwater dewatering system from Lake Street to the Upjohn Park footbridge.
Project Management Activities
- Continued weekly progress meetings with City of Kalamazoo;
- Scheduled restoration work in SA6 and SA7 to begin on September 17; and
- Conducted data validation for post-removal confirmation sediment samples collected from Axtell Creek.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The major PRP for this portion of the Allied Paper Inc./Portage Creek/Kalamazoo River Superfund site was dissolved through bankruptcy proceedings in April 2010. Other PRPs are being evaluated.
