MINNEAPOLIS (AP) — Officials from Great Lakes states are making a renewed push to win approval of a long stalled proposal for adding a new lock to the Soo Locks complex, a chokepoint that connects Lake Superior to the lower Great Lakes.
Only one of the two working locks there handles large iron-ore boats. A Homeland Security study says an unplanned six-month closing of the Poe Lock due to an accident or terrorist attack would shut down much of the U.S. steel industry. The resulting economic shockwaves could cost the country 11 million jobs. That’s more than the Great Recession. A Treasury Department report projects a net economic benefit of up to $1.7 billion from a new Soo Lock.
A look at some of the questions the project presents:
THE SOO LOCKS
The Soo Locks at Sault Ste. Marie, Michigan, carry all the shipping traffic between Lake Superior and the rest of the Great Lakes, including ships bound for the Atlantic Ocean — making more than 10,000 one-way trips and taking about 80 million tons of cargo annually.
The cargo consists mostly of iron ore and coal, but also includes grain and even wind-turbine blades. Boats longer than 730 feet or wider than 75 feet, which carry about 85 percent of the cargo passing through the locks, are too big for the MacArthur Lock. The big concern is that nearly all iron ore mined in the U.S. goes through the locks on the way to steel mills elsewhere, mostly on boats that must use the Poe Lock instead.
The U.S. Army Corps of Engineers doesn’t have an official price tag for a new lock, but similar projects have cost about $1 billion, said Lynn Rose, spokeswoman for the Corps’ Detroit district.
A Department of Homeland Security study from 2015 called the Poe Lock “the Achilles heel of the North American industrial economy.”
It concluded that an unexpected six-month shutdown of the lock would be “catastrophic” because of the disruption to the supply chain that extends from the iron mines of Minnesota and Michigan, to the steel mills of the Great Lakes region, onward to manufacturers that depend on steel — especially the automakers. It projected a $1.1 trillion loss in gross domestic product.
“Almost 11 million people in the United States and potentially millions more in Canada and Mexico would become unemployed due to the production stoppage, and the economy would enter a severe recession,” the report said.
“There are no plans or solutions that could mitigate the damage to the manufacturing industries dependent on this supply chain.”
Vanta Coda, executive director of the Duluth Seaway Port Authority, said he’s often asked if he believes that figure.
He said his reply is always: “What if it’s only 5 (million)? What if it’s only six? What if it’s only eight?” No matter what, he said, the risk is too great to ignore.
Congress first authorized a new Poe-sized lock in 1986 but never designated a way to pay for it. A bipartisan group of lawmakers led by Sen. Debbie Stabenow, D-Michigan, and Rep. Jack Bergman, R-Michigan, introduced legislation in June to try again.
They won backing on Monday from the Great Lakes Commission. The commission, which includes officials from eight states and two provinces, is holding its annual meeting this week in Duluth.
The vice chairman of the group, John Linc Stine, said there are reasons for hope because there’s a growing consensus about the danger of economic vulnerability and the need for redundancy. But Stine, who’s also commissioner of the Minnesota Pollution Control Agency, acknowledged there’s a lot of competition for federal infrastructure dollars.
THE ECONOMIC BENEFIT
Modernizing the Soo Locks made a Treasury Department-commissioned list last fall of 40 proposed projects that would have major economic significance. It projected the net economic benefit of rehabilitating the Poe Lock or adding another lock at $600 million to $1.7 billion.
The Poe Lock is nearly 50 years old while the MacArthur Lock is more than 70 years old. The report said the Poe Lock are expected to have to be shut down with increasing frequencty.
But infrastructure “serves in silence,” Coda said. People don’t think about it until something goes wrong, he said.
Backers of a new lock are hoping they don’t have to wait for a catastrophe.
“We can’t wait until it breaks,” Coda said.
