 Cleanup work on a three-mile stretch of the Tittabawassee River along the Dow Chemical Co. plant in Midland is scheduled to being in the spring.

It is one of the first steps in a several-year initiative of the Environmental Protection Agency and Dow Chemical Co. to clean the river of contaminants, which include dioxins and furans.

Diane Russell, remedial project manager at the EPA’s Saginaw Field Office, said the Segment 1 project will take two construction seasons to complete. While dioxins are not a focus in the section, the cleanup will target several different contaminants, including arsenic, that in the stretch of river.

Russell provided an overview of the 2012 plan at Monday's Saginaw-Tittabawassee Rivers Contamination Community Advisory Group meeting at Saginaw Valley State University.

Dow Chemical has acknowledged leaking dioxins and furans, chemical byproducts of the chlorine manufacturing process and combustion, among other chemicals into the Tittabawassee River from the late 1890s to the 1970s.

The cleanup, including interim work to prevent residents from coming into contact with contaminated soil, began in January.

Construction work for the next river section, Segment 2, likely will not start until 2014, when Segment 1 is complete, Russell said. Segment 3 should start in 2015. EPA officials will plan for both sites in the year prior. The agency sectioned off the river into the approximately 3- to 4-mile segments to manage the cleanup, she said.

Segment 3 runs through Freeland.

Russell said the EPA will complete the evaluation of sediment traps and address any highly-contaminated areas throughout the cleanup process as necessary in 2012.

In 2011, the EPA planned for Segment 1 cleanup, and Dow workers cleaned a heavily-contaminated island in the Tittabawassee River in Saginaw Township and many high-use properties along the river to prevent residents from coming into contact with contamination.
