We have advised the Ontario Ministry of Environment and Climate Change that we were required to extend coking times at our No.2 and No.3 Coke Plants, which can increase stack emission opacity.

The extended times are due to an unexpected coal quality issue that required our teams to redirect coal from the process, and required longer coking times for the coal already in the ovens.

We have advised Ministry officials that we have responded immediately and expect the stack opacity to reduce over the next 72 hours.
