2.1.1 Narrative
Dredging operations in Axtell Creek were delayed by high PCB test results at the target excavation depths (see Sections 2.1.2, 2.2 and 2.2.2). Dredging will contine on August 8 once the groundwater dewatering system has had sufficient operational time to capture groundwater. Crews began preparations for excavation in SA5-D and SA5-C (Upjohn Park). A creekwater bypass pump system, groundwater dewatering system, and temporary bridge were installed to facilitate contaminated sediment removal operations. 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 July 21 to August 3, EPA, START and ERRS contractors/sub-contractors conducted the following activities:
Site Activities - Axtell Creek
- Completed post-excavation sampling for the initial over-excavation depths in grids AXC-1 thru AXC-5 to determine if cleanup goals were met. Only the sample result from grid AXC-5 met the performance standard of 10 mg/kg PCBs. None of the confirmatory sample results from any of the grids met the performance standard goal of 1 mg/kg PCBs. Based on these results, additional core sampling was conducted (see Section 2.2.2) and additional PCB-contaminated material was identified. All grids will undergo a second over-excavation (see details in Section 2.2). Grids AXC-1 through AXC-5 are estimated (est) to be over excavated as follows once the de-watering system is installed.

- Completed installation of groundwater de-watering system around perimeter of excavation;
- Began construction of a 12" discharge pipeline from the John Street pump station to Vine Street to prevent Axtell Creek discharge from filling SA5-D and SA5-C excavation areas in Portage Creek and enhance existing pump capacity to handle extreme rain events;
- Pumped and treated contaminated contact water in AXC-2 to AXC-4 in EPA's mobile wastewater treatment system; and
- Conducted personnel air monitoring, stream turbidity, and perimeter particulate monitoring in work areas with all results below action levels.
Site Activities - Staging Pad
- Solidified and loaded out 511.87 tons of TSCA (> 50ppm PCBs) contaminated sediments for disposal at Wayne Disposal landfill in Belleville, Michigan;
- Solidified and loaded out 431.11 tons of non-TSCA (< 50ppm PCBs) contaminated sediments for disposal at C&C Landfill in Marshall, Michigan; and
- Treated 140,415 gallons of contaminated contact water in EPA's mobile wastewater treatment plant, with a total of 378,678 gallons treated to date.
Site Activities - SA6
- Spread topsoil, grass seed and straw on the top of the creek banks and impacted adjacent properties;
- Began installation of new fencing on the west bank which was removed to facilitate contaminated sediment removal; and
- Installed new fencing at two properties on the east bank which was removed to facilitate installation of the 30" bypass pump system disharge line.
Site Activities - SA5-D & SA5-C
- Completed installation of temporary fencing around work area on east bank;
- Installed and tested creek bypass pumping system at Lake Street bridge;
- Constructed two 18" discharge lines on west bank from Lake Street pump station to Vine Street to handle discharge from creek bypass pumping system;
- Began installation of groundwater dewatering system; and
- Installed temporary steel bridge to facilitate transport of excavated sediments to staging pad without using public roadways.
Project Management Activities
- Continued weekly progress meetings with City of Kalamazoo;
- Awarded contract to implement restoration plans for SA5, SA6, and SA7;
- Awarded contract to re-pave or fix damaged asphalt in paved lots used to access SA6; and
- Conducted data validation for post-removal confirmation sediment samples and investigatory cores 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.

Only one post-excavation confirmatory sample result from the second round of excavation in grids in Axtell Creek was under the performance standard of 10 mg/kg. All of the second round of confirmatory sampling results at target dredging depths in the grids were above the performance standard goal of 1 mg/kg as listed below (see table).
