would be required under EPA rules". The lawsuit between Cominco and the Colville Confederated Tribes sparked more tensions between Canada and the U.S. over transborder environmental laws. As a Canadian company, Cominco felt that their operation was being unfairly targeted because the lawsuit was ordering them to follow an American governing body's orders to clean up Lake Roosevelt. Cominco also objected to the implication in the lawsuit that it was the only company responsible for the pollution of Lake Roosevelt. In 1994, Cominco stopped depositing smelting byproducts into the Columbia River and in 2004 reportedly spent about $1 billion modernizing the Trail plant and reducing its emissions.
