2.1.1 Narrative
Dredging and backfill operations continued in SA5D (Upjohn Park). Visible gross contamination and elevated PCB test results at target excavation depths (see Sections 2.1.2 and 2.2.2) required additional excavation to meet the clean-up performance standard. Dredging operations began in SA5C on September 25.
2.1.2 Response Actions to Date
From September 15 to September 28, EPA, START and ERRS contractors conducted the following activities:
Site Activities - SA5D & SA5C
- Excavated contaminated sediments from grids SA5D-14 to SA5D-16 (see table below for details) and placed backfill materials / coir logs according to the site restoration plan; and
- Excavated contaminated sediments from grids SA5C-1 to SA5C-3.

Site Activities - Staging Pad
- Solidified and loaded out 1077.58 tons of TSCA (> 50ppm PCBs) contaminated sediments for disposal at Wayne Disposal landfill in Belleville, Michigan;
- Solidified and loaded out 982.05 tons of non-TSCA (< 50ppm PCBs) contaminated sediments for disposal at C&C Landfill in Marshall, Michigan; and
- Treated 63,909 gallons of potentially contaminated contact water in EPA's mobile wastewater treatment plant, with a total of 542,182 gallons treated to date.
Project Management Activities
- Continued weekly progress meetings with City of Kalamazoo;
- Conducted data validation for additional post-removal confirmation sediment samples collected from SA5D;
- Continued development of seasonal site shut-down / demobilization plan; and
- Continued discussions with property owners in SA5A and SA3A regarding site access, preparation and restoration.

A summary of removal activities that will take place from September 29 through October 12 include:
Site Activities - Staging Pad
- Continue de-watering and solidification of excavated sediments for transport;
- Continue transport of solidified sediments for disposal; and
- Continue treatment of contaminated water in EPA's mobile waste water treatment plant.
Site Activities - SA5D & SA5C
- Excavate, solidify and transport for disposal contaminated sediments from Portage Creek in grids SA5C-4 to SA5C-6 (between Crosstown Parkway and Vine Street);
- Backfill and install coir logs in grids SA5C-1 to SA5C-6 according to Restoration Plan;
- Attempt to excavate grid SA5D-17 once dam near Crosstown Parkway is removed;
- Remove isolation groundwater de-watering system in SA5C; and
- Begin demobilization of all engineering and environmental controls.
Project Management Activities
- Continue weekly progress meetings with City of Kalamazoo;
- Conduct pre-construction sampling and contaminated sediment confirmation sampling of SA5A & SA3A;
- Obtain access agreements for properties on west creek banks in SA5A and SA3A; and
- Meet with Trustees and John Street Staging area property to discuss future restoration of the staging pad property.

2.2.2 Issues
- Excavation of grids to initial target depths revealed visual paper pulp material. Therefore, many grids were over-excavated until that material was no longer visible. Grids SA5D-14,SA5D-15, and SA5C-1 were sampled at the initial target depths (see table below), to verify that the suspected paper pulp material exceeded project performance standards. All confirmatory sample results from over-excavation in grids SA5D-14 to SA5D-16 and SA5C-1 to SA5C-3 were under the performance standard of 10 mg/kg as well as the performance standard goal of 1 mg/kg as listed below (see table).

ND: Non-detect dup: duplicate sample location
- The additional over-excavation in grids SA5D-14 to SA5D-16 and SA5C-1 to SA5C-3 resulted in increased costs and added expenses for personnel, equipment, transportation, disposal, sampling and backfill material.
- A significant rain event occurred on September 22 & 23, causing over-topping of the sheet pile wall at Lake Street andsand bag dam at Crosstown Parkway. Upstream water entered the SA5C excavation area. This event caused further delays, with all activities except water management suspended on September 24.
- A pump failure in a bypass pump occurred the night of September 2, leading to over-topping of sheet pile wall at Lake Street and the sand bag dam at Crosstown Parkway. This allowed water to enter the SA5C excavation area. Although it did not completely shut down excavation activities, additional time was spent managing water from this event.
