EAST CHICAGO, Ind. (AP) — The Environmental Protection Agency says dredging of a ship canal in northwest Indiana has begun as environmental regulators continue to study off-site disposal options for highly contaminated sediments.

The (Northwest Indiana) Times reports that Army Corps of Engineers contractors began dredging work at the Indiana Harbor Ship Canal in East Chicago on Monday. The Army Corps says removing the 120,000 cubic yards (91,750 cubic meters) of sediment will likely finish in the fall.

Natalie Mills is project manager for the Army Corps. She says sediment containing more than 50 parts per million of polychlorinated biphenyls won’t be dredged until off-site disposal is finalized.

The Army Corps has applied for a Toxic Substances Control Act permit. The EPA and the state Department of Department of Environmental Management are conducting a feasibility study and remedial design for removal of the sediment.
