Tittabawassee river clean-up and dioxin information
The Dow Chemical Company (Dow), began operations of the Midland Plant in 1897. The 1,900-acre facility borders the east side of the Tittabawassee River and the south side of the city of Midland. Starting in the early 1900’s, Dow began the manufacturing of chlorine-based products, which resulted in the formation of inadvertent byproducts called dioxins and furans. Liquid wastes from the facility were discharged directly into the river, causing elevated dioxin levels in and along the Tittabawassee River and downstream areas. These waste disposal practices have resulted in on- and off-site contamination that settled in sediments and built-up in riverbanks and floodplain areas. Off-site contamination extends over 50 miles downstream through the Tittabawassee and Saginaw Rivers and into Saginaw Bay.
In 2010, Dow, the Department of Environment, Great Lakes, and Energy (EGLE), and the United States Environmental Protection Agency (U.S. EPA), entered an Administrative Settlement Agreement and Order on Consent (AOC) for the Tittabawassee and Saginaw Rivers and Floodplains, and Saginaw Bay federal Superfund site. The AOC clarifies Dow’s clean-up obligations to address the Midland and downstream floodplain areas contamination that resulted from historic operations. In addition, Dow is responsible to take actions under a Natural Resource Damage Assessment under the supervision of the U.S. Fish and Wildlife Service.

Dioxin information
Dioxins are a group of chemically related compounds that are persistent environmental pollutants. Dioxins are found throughout the world in the environment, and they accumulate in the food chain, mainly in the fatty tissue of animals. More than 90% of human exposure is through food, mainly meat and dairy products, fish and shellfish. For more information, visit EGLE’s dioxin webpage.
What is EGLE doing?
On January 18, 2022, EGLE, the Department of Health and Human Services (DHHS), and the Department of Agriculture and Rural Development (MDARD), hosted a public meeting on raising chickens and livestock in Midland and Downstream river areas.
The following links were also shared in the public meeting presentation and in the meeting chat:
