The U.S. House of Representatives has appropriated $300,000 to investigate why steel pilings at the Port of Duluth and Superior are corroding up to 10 times faster than expected.
Congressman Jim Oberstar of Duluth, Minn. said he’s confident the Senate will pass its own version of the Energy and Water Development Appropriations Bill and start the money flowing. The U.S. Army Corps of Engineers will conduct the research.
Researchers could get another $100,000 in state funding under a bill that’s now in a House conference committee.
A study prepared for the Corps said replacing the steel pilings alone could cost more than $100 million.
