On June 27, 2007, U.S. EPA ordered The Dow Chemical Company (Dow)
to negotiate an Administrative Order on Consent, to address removal
of extremely elevated levels of dioxin-contaminated sediment within
Reach D of the Tittabawassee River near Midland,
Michigan. Dow contractors mobilized to the site on July
9, 2007. Dow agreed to the terms of the Order and on July
12, 2007, the Order was signed by the Regional Administrator and
Dow. For additional background information please see the
site profile.

On July 9, 2007, the removal action at the Reach D site was
initiated by Dow pursuant to permits previously issued by the
Michigan DEQ. Dow’s contractor began positioning
equipment on a work barge to begin the preparation of driving
temporary sheet piling in the river to delineate the area of highest
dioxin-contamination. Dow’s contractor has nearly
completed all construction on the sediment pipeline and sediment
dewatering pad on the facility. Water from the sediment
dewatering pad will be treated in Dow’s Waste Water Treatment Plant
and discharged to the river. On-Scene Coordinator (OSC)
Brian Schlieger provided oversight with assistance from U.S. EPA’s
START Contractor, Weston Solutions, Inc.
The following tasks
have been completed by Dow's Contractor during the period from July
9-18, 2007:
• Mobilization and placement
of equipment and sheet piling on a work barge in the
river.
• Placement of 142 sheets of sheet
piling (equivalent to approximately 290 feet) along the east bank of
the river
• Grading for all three cells
of the Reach D Sediment Dewatering Pad
•
Pouring of concrete for the sump within the settling pond cell at
the Sediment Dewatering Pad
•
Installation of liners for water decanting cell of the Sediment
Dewatering Pad
• Establishment of The
Sediment Transfer Line from the Reach D Sediment Removal area to the
Sediment Dewatering Pad
• Establishment of
electrical service lines in the Sediment Dewatering
Pad
• Establishment of air monitoring
stations throughout the Reach D project area
|
|
Dow's contractor will continue to place sheet piling in the river
prior to comencement of dredging operations. Contractors
will also continue completion of the Sediment Dewatering Pad and the
Sediment Transport Line. Additional Dow contractor
personnel are scheduled to be mobilized to the site the week of July
23. |

Review and approval of the Project Work Plan and
associated Site-Specific Health and Safety Plan by U.S.
EPA is pending. |
