Teck Trail Operations insists it has taken steps to ensure the health of the Columbia River.
This as the Colville Tribes have filed a final brief in their US Court of Appeals battle with the local smelter.
Teck won’t comment on the case while it’s before the courts.
But they say they’ve spent over $80 million US on a remedial investigation and feasibility study to determine if historical practices have impacted the river.
The Colville Tribes feel teck has been avoiding its obligations to clean the river.
