KOCHVILLE TWP — The U.S. Environmental Protection Agency is seeking public comment on the Segment 1 cleanup of the Tittabawassee River.
The segment is a 3-mile section of the river adjacent to Dow Chemical Co.’s Midland plant. The area is contaminated with several different chemicals, including arsenic. Dioxins and furans are not EPA’s major concern at this location, said Remedial Project Manager Mary Logan last month.
The comment period is open and ends Aug. 31. View the full cleanup documents here.
Segment 1 is divided into six areas called sediment management areas, and the EPA recommends four different cleanup methods.
• Segment management area 1: Place a clean cap over contaminated sediment to isolate and stabilize it.
• Segment management areas 2 and 3: Remove and treat a pollutant called dense nonaqueous phase liquid, a liquid, tarry substance heavier than water. Isolate other contaminated sediment with sheet pile and a cap, and capture and treat water within the sediment
• Segment management areas 4 and 5: Place a clean cap over contaminated sediment.
• Segment management area 6: Dredge and dispose some contaminated sediment, remove and treat dense nonaqueous phase liquid, isolate remaining contaminated sediment with sheet pile and a cap, and capture and treat water within the sediment
There are no residential properties on either side of the river in that
Work at the Tittabawassee River this year is the start of an interim cleanup to protect residents from coming into contact with dioxins, furans and other harmful pollutants in the flood plain. In coming years, Dow and the EPA will complete a full and complete cleanup of the Tittabawassee and Saginaw rivers.
Dioxins are furans are chemical byproducts of combustion. Dow has acknowledged releasing the chemical into the Tittabawassee River from the 1930s to the 1970s.
Anyone wishing to comment in person can attend a meeting at 6:30 p.m. Tuesday at Saginaw Valley State University’s Curtiss Hall, 7400 Bay in Kochville Township.
Earlier that day, EPA and Michigan Department of Environmental Quality representatives are hosting an informal session to speak with residents from 2 p.m. to 4 p.m. Tuesday at the Dow Memorial Library, 1710 W. Saint Andrews in Midland.
