U.S. Steel to close iron and steel-making operations in Hamilton

U.S. Steel plans to close its iron and steel-making operations in Hamilton by the end of the year, but coke production at the plant will continue, officials say.

Mario Longhi, CEO of U.S. Steel Corp., said in a conference call Tuesday that it will close the operations by Dec. 31.

Forty-seven non-union employees will be "affected," according to U.S. Steel spokeswoman Courtney Boone.

“Notice will be provided to those employees affected, and every effort will be made to reassign them," she told CBC News. “The permanent shutdown affects the iron and steel-making operations, which have been on temporary idle since late 2010.”

The blast furnace steel shop and casters will be permanently shut, she said. “Coke making and finishing at the Hamilton works will continue.”

The company said it will take a non-cash charge in its fourth quarter of approximately $225 million related to the decision.

U.S. Steel acquired the integrated steel-making operations when it bought Stelco, one of Canada's largest steel manufacturers, in 2007.

The company's website says it employs approximately 2,200 people at the 445-hectare production complex.
