Today, the U.S. Environmental Protection Agency added the Upper Columbia River Site in northeast Washington to the Superfund National Priorities List, the list of sites throughout the United States and its territories where historic releases of hazardous substances, pollutants, or contaminants pose significant threats to human health and the environment.

EPA has determined that soils within the site are contaminated with lead and arsenic and pose an unacceptable risk to residents at affected properties, particularly to children and women of childbearing age. Additionally, sediments in the river are contaminated with metals, including zinc, copper, cadmium, selenium, lead and mercury, that pose a risk to fish, wildlife, birds, and other organisms that live in and along the river.

The primary source of contamination at the site is the Teck Metals Ltd. smelting facility in Trail, British Columbia, approximately 10 river miles upstream of the international boundary. The former Le Roi smelter in Northport, Washington, also contributed contamination.

“EPA’s decision to list the Upper Columbia River Site on the National Priorities List will strengthen and boost our collective efforts to address a legacy of contamination at the site,” said Washington Governor Jay Inslee. “By unlocking additional federal resources, this move will help ensure that this part of our state is home to a thriving economy and ecosystem for generations to come.”

"The Colville Tribes is pleased to hear that the EPA has listed the Upper Columbia River as a Superfund site,” said Jarred-Michael Erickson, the Chairman of the Confederated Tribes of the Colville Reservation. “The river has been used for decades as a waste disposal site and that pollution not only damaged the physical river, but has also cost the Tribes enormously in terms of lost use and enjoyment of the river. Past leaders and staff of the Colville Tribes initiated and sustained the work of cleaning up the river, and today the Colville Tribes has been in litigation with Canadian company Teck Resources Limited for over 20 years to make them take responsibility for remediation of the river under United States environmental law and for damages to natural resources. While that litigation continues, a Superfund listing will unlock access to funds necessary for a thorough remediation of the river, and the listing reflects the high priority for cleanup that this site deserves. Everyone is better served if we clean the river now rather than pass the problem on to future generations."

“The Spokane Tribe supports EPA acting now to place the Site on the NPL,” said Gregory Abrahamson, Chairman of the Spokane Tribal Business Council. “The Upper Columbia River site includes areas within the Spokane Tribe's traditional homeland and current Spokane Reservation whose natural resources have been and continue to be integral to our subsistence and culture since time immemorial. Historic and ongoing releases of hazardous substances to the site threaten or directly affect the health and welfare of our members, our economic security, and the Spokane Tribe's political integrity. Assessing the nature and extent of such contamination and any associated risks it poses to tribal health and resources is as imperative today as it was in 2003, when the Spokane Tribe first supported EPA's proposed placement of the site on the NPL. Nearly 20 years later, the RI/FS process is ongoing, and we urge EPA to further investigations of downstream river areas proximate to the Spokane Reservation. We remain acutely concerned that many more generations of the Spokane people must endure uncertainty about Site conditions and risks due to the presence of hazardous substances. Listing will also allow funding for EPA to better characterize the nature and extent of risks posed by hazardous substances at the Site, particularly in the downriver reservoir areas proximate to the Spokane Reservation, and to fund participation in the remedial process by affected state and tribal governments - including the Spokane Tribe – if Teck refuses to fund them.”
