Driven by customer demand and as part of the Company's ordinary course of business planning, U. S. Steel has begun the process to restart the operation of one of two blast furnaces (“B”) at Granite City Works.

“After several months of carefully analyzing customer demand, we made the decision to restart a blast furnace,” said David B. Burritt, President and CEO of U. S.
