POLREP #7 - 9/28/2007
On-Scene Coordinator - James Augustyn/Brian Schlieger
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 soil from an eroding river bank within Reach JK of the Tittabawasse River near Midland, Michigan. 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.
Reach JK will be divided into two areas. The area along the river bank where contaminated soil will be excavated will be designated JK-1, and an area further back from the river bank where clean soil will be used to cap contaminated soil will be designated JK-2.
On-Scene Coordinator (OSC) Jim Augustyn is providing oversight with assistance from U.S. EPA's START Contractor, Weston Solutions, Inc.
The following tasks are currently on going:
- Installation of an irrigation system to water vegetation planted as part of the Site Restoration Activities.
- Placing of a mulch blanket over the JK-1 area.

The following tasks have been completed by Dow's contractor during the period from September 20 - 26, 2007:

Topsoil was placed just south of the parking area location in JK-2 from where the gravel was removed. Additional site activities included the completion of the chain linked fence around the JK-2 wooded area and crews planted trees in the JK-1 area.
- Saturday, Sept 22nd: The planting of 110 ball rooted trees in the JK-1 area was completed.
- Monday, Sept 24th: Dow's contractor continued placing topsoil on the Site. Dry grass seed/ wetland mix was planted at both JK-1 and JK-2 non-wooded areas. Additional site activities included grading of the newly constructed parking area and relocating the silt curtain from the water's edge to the east edge of the bench area (fish gravel mix area) in JK-1.
- Tuesday, Sept 25th: The placement of topsoil on the Site was completed. Seeding of grass / wetland grass was also completed in JK-1 and JK-2 areas. Mulch blanket was laid down on approximately half of JK-1 and all the newly planted trees were watered. Grading of the parking area was also completed.
- Wednesday, Sept 26th: Dow's contractor continued to lay mulch blanket in the JK-1 area. Grass / wetland grass was placed along the eastern edge of the mulch blanket. The crew also assembled an irrigation system to water vegetation planted as part of the Site Restoration Activities.

The following tasks are soon to be implemented:
- Placement of straw mulch on the JK-2 non-wooded area.
- Planting of bare rooted trees in late October or early November as part of the Site Restoration Activities.
- Removal of sediment fence around the perimeter of the site once the grass has begun to grow.
