Tittabawassee River Floodplain

EPA, working with the Michigan Department of Environmental Quality, has a cleanup planfor contaminated soil in frequently flooded areas along the Tittabawassee River downstream from Midland. Many properties in the Tittabawassee River floodplain will be affected by EPA's cleanup decision. The multi-year floodplain cleanup will start in 2015.

The Tittabawassee River floodplain starts in Midland below the Dow Chemical Co. plant and extends through Midland and Saginaw counties.

EPA has selected a plan to clean up dioxin-contaminated soil from the Tittabawassee River Floodplain.

The floodplain includes about 4,500 acres and extends along 21 miles of the river below the Dow Chemical Co. plant in Midland. EPA's floodplain cleanup will protect all people who live, work and play along the Tittabawassee River.

Not all areas in the floodplain will need a cleanup. Because floodplain land is used in different ways, EPA’s plan uses a combination of steps. In homeowners' yards that are maintained for typical backyard uses, if tests show a contamination level greater than 250 parts of dioxin in a trillion parts of soil – or ppt – soil will be dug up and hauled away. Soil will be replaced and grasses and plants restored. For other areas such as farms, parks, commercial properties and natural areas, if tests show a contamination level greater than 2,000 ppt, soil will either be dug up and hauled away or covered with clean soil. EPA will work with each property owner on the right approach and after cleanup, these areas will be replanted.

Under a legal agreement with EPA, Dow will implement the cleanup with EPA oversight (see Consent Order below).
