Batteries #13 and #14 to be Hot Idled

08/26/2025

U. S. Steel on Wednesday plans to begin the process of removing the coke from batteries #13 and #14 to inspect for any damage to the ovens and determine if they can be repaired. The next step in that process is placing them into a hot idle state to maintain their integrity. No coking or production will be taking place. Without placing them on hot idle, the batteries will not be able to function ever again. We expect this process to take a few days, and we do not expect any elevated non-particulate pollution as a result of this process.  There is potential for some ashy particles to be released as the coke is removed from the ovens.

U. S. Steel is working to mitigate any potential emissions and keeping ACHD informed. We will provide additional updates as they become available.
