U.S. Steel has idled the “B” Battery at its Clairton Coke Works near Pittsburgh following a “release of excess pressure” inside a section of the battery on Feb. 5.

“The battery has been taken off-line and will remain off-line until a root cause can be determined and any necessary and appropriate repairs can be made,” a USS spokeswoman said in a statement to SMU.

“This is a rare occurrence that was isolated to a small area of the plant, and there is no risk to the community,” she added.

The Pittsburgh-based steelmaker stated it followed all safety and environmental protocols and is conducting a thorough investigation.

“Some employees were taken to a local hospital where they underwent evaluations. They were released and allowed to return to work,” the spokeswoman said.

She noted that over the last five years, U.S. Steel has invested over $750 million in improvement projects at its Mon Valley Works facilities. This includes roughly $100 million annually being spent at the Clairton facility on environmental compliance.
