The Lake Roosevelt National Recreation Area in Washington has welcomed many tourists to its sparkling waters and sandy beaches for decades. These popular waterfronts have also been polluted by waste dumped into the Columbia River from the world’s largest lead and zinc smelter in Trail, British Columbia. This pollution is a type of fine black sand known as “slag.” The State of Washington and the Colville Indian Tribes filed suit against the Canadian company, Teck Metals Ltd., demanding that the company pay to clean up the pollution pursuant to the U.S. Superfund law. Now, a U.S. District Judge must decide whether or not the federal court has jurisdiction over this Canadian company. The company argues that jurisdiction is improper because Teck Metals is a Canadian corporation that does not do business in Washington and asserting jurisdiction over the company would interfere with the sovereign authority of Canada. However, the State believes that because Teck Metals has already acknowledged that it released pollution into the state of Washington, it is subject to U.S. jurisdiction & U.S. environmental laws.
