NEW YORK — A dock wall at ArcelorMittal USA Inc.’s Burns Harbor, Ind., facility collapsed Tuesday morning while cargo was being offloaded from a vessel.

The incident didn’t affect production or the facility’s ability to serve customers, a spokeswoman for the Chicago-based company told AMM in an e-mail.

There has been no impact on the Port of Indiana and the company is waiting for the U.S. Coast Guard to inspect the vessel, she added.
