EPA proposes adding the Upper Columbia River, WA to Superfund List
The U.S. Environmental Protection Agency announced today it is proposing to
add the Upper Columbia River Site in northeast Washington to the National
Priorities List, the list of hazardous waste sites in the United States
eligible for cleanup financed under the federal Superfund Program.
“Today’s action builds on decades of efforts to clean up the river and
protect the health of people who live, work, and recreate in and near the
Upper Columbia,” said EPA Region 10 Administrator Casey Sixkiller.
“Listing this site on the National Priorities List unlocks the full suite of
tools and resources of EPA’s Superfund program to address this complex site
and take additional steps to protect young children from harmful levels of
lead.”
The agency has determined that soils contaminated with lead and arsenic pose
unacceptable risk to residents at affected properties, particularly to
children. EPA determined that soil in at least 194 residential areas contain
lead at levels that exceed the agency’s new screening level for residential
lead contamination.
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.
In November 2023 letters to Washington Governor Inslee, Chairman
Jarred-Michael Erickson of the Confederated Tribes of the Colville
Reservation, and Chairman Gregory Abrahamson of the Spokane Tribal Business
Council, EPA requested concurrence with its plans to propose listing the site
on the NPL. EPA received responses from the Governor and the two Tribes
concurring with EPA’s assessment that the NPL is the best way to ensure
cleanup of lead and other metals that pose risks to people and the environment
in the study area.
Governor Inslee responded, “The legacy of contamination and risks to human
health and the environment justify adding the site to the National Priorities
List. It is time to turn needed attention to clean up the Upper Columbia River
Site for all who depend on it as a treasured natural and cultural resource.”
“Historical disposal and discharges of wastes and emissions from smelter
operations have contaminated the UCR Site and pose a risk to human health as
well as to the sovereignty and economic security of the Colville Tribes,”
said Jarred-Michael Erickson, Chairman of the Confederated Tribes of the
Colville Reservation. “An NPL listing will allow access to resources that
are much needed for remediation of the UCR Site.”
“The Tribe supports EPA acting now to propose placing the Site on the
NPL,” said Gregory Abrahamson, Chairman of the Spokane Tribal Business
Council. “Once listed, EPA will have access to the Superfund to timely
proceed with remedial actions.”
In 2006 EPA and Teck Metals Ltd. entered into a Settlement Agreement along
with Teck American Inc. and U.S. Department of Justice, to complete studies
that establish the nature and extent of contamination. These ongoing studies
include human health and ecological risk assessments. The Human Health Risk
Assessment was completed in 2021, showing unacceptable risks to people’s
health caused primarily by lead and other metals to a lesser extent. The
ecological risk assessments are underway.
The enforceable agreement does not require Teck to complete a comprehensive
cleanup of the site. Listing the site on the NPL allows EPA to access
Superfund dollars for cleanup activities which can also help ensure a more
timely cleanup.  
Public comment period and next steps
The proposal announced today will be published in the federal register and a
60-day public comment period will follow from March 7 – May 6, 2024.
For more information on this site, the Federal Register notice, and how to
submit comments, visit the EPA website on Current NPL Updates: New Proposed
NPL Sites and New NPL Sites.
For information on Upper Columbia River site background and ongoing studies
visit the Upper Columbia River Study Area website.
Upon completion of the comment period and review of the public comments, EPA
will determine whether to officially list the site to the NPL. A final
decision could come as early as September 2024.
Background on Superfund and the National Priorities List
Nationwide, thousands of contaminated sites, from landfills to processing
plants to manufacturing facilities, exist due to hazardous waste being dumped,
left out in the open, or otherwise improperly managed. President Biden’s
Bipartisan Infrastructure Law accelerates EPA’s work to clean up this
pollution with a $3.5 billion investment in the Superfund Remedial Program.
This historic investment strengthens EPA’s ability to tackle threats to
human health and the environment at Superfund National Priorities List sites.
The law also reinstates the Superfund chemical excise taxes, making it one of
the largest investments in American history to address legacy pollution.
Background on health risks from lead exposure
Lead poses a health risk to people through direct contact and incidental
ingestion of soil, including from yards, gardens, and/or play areas. In
infants and children, lead can severely harm mental and physical development –
slowing down learning and damaging the brain. In adults, lead can cause
increased blood pressure, heart disease, decreased kidney function, and
cancer.
EPA has updated its residential soil lead guidance, a significant milestone in
the agency-wide?Strategy to Reduce Lead Exposures and Disparities in U.S.
Communities. EPA made this change because protecting children from lead
exposure is a top priority, and because the science has shown that lead
exposure is harmful to children’s health at lower levels than was reflected
in previous agency guidance in 1994.  
EPA makes cleanup decisions specific to each site, including setting cleanup
levels, using site-specific factors such as risk factors, community input, and
the level of lead that was already in the area (called the background
level).
