Federal officials are planning the second round of a Dow Chemical Co.-funded cleanup of the Tittabawassee River.
MLive.com reports Friday that crews are finishing work on the first section, a three-mile stretch next to Dow's Michigan Operations plant.
U.S. Environmental Protection Agency officials expect to have a plan finished within a couple of months for a four-mile section downstream. Work on that segment is expected to begin next spring.
It's part of a plan to remove dioxins and other contaminants from the Tittabawassee and Saginaw rivers, as well as Lake Huron's Saginaw Bay. Cleanup is expected to take several more years.
Midland-based Dow released dioxins into the environment through air and water emissions from the 1890s to the 1970s. Dioxin is a group of toxic byproducts from industrial processes.
