ALGOMA STEEL REPORTS INCIDENT AT COKE-MAKING PLANT

In the early hours of Saturday, Jan. 20, 2024, there was a collapse of a structure supporting utilities piping at Algoma Steel Group Inc.'s coke-making plant. There have been no injuries, and the Algoma Steel team is managing the occurrence with the safety of its employees and the community as its highest priority.

The incident resulted in a coke oven gas main failure generating abnormal coke oven gas flaring and air emissions. Additionally, a quantity of effluent left the site early this morning and entered the adjacent waterway. The source of the discharge has been identified, and containment efforts are under way.

Algoma Steel has notified community and regulatory stakeholders, and is working to mitigate and monitor any possible impacts to the environment, its community and continuing operations.

While coke production is currently interrupted, all other departments are operating normally. Algoma Steel advises that it has adequate coke supply on hand, and it does not anticipate an impact on customer shipments at this time.

Algoma Steel is performing a comprehensive assessment of the damage, and is focused on managing the occurrence in the safest possible manner, ensuring the seamless continuation of operations and safeguarding public safety, and minimizing any environmental impact.
