Purpose
This report is an update on work efforts in the
Columbia River Basin to reduce toxic contaminants
which threaten the health of people, fish and wildlife
in the Basin. This work has been led through a broad
effort based on coordination and partnerships by
the Columbia River Toxics Reduction Working Group
(Working Grout . Since 2005, the Working Group
has been working collaboratively to develop and
implement toxics reduction and assessment actions
including: water quality monitoring, agricultural best
management practices (BMPs) and performance-
based certification programs, green infrastructure,
green chemistry, public education, collection and
disposal of pesticides and pharmaceuticals, and the
clean-up of contaminated sites.
Specifically, this report provides information derived
from the Working Group partners on the most
successful actions in reducing and assessing toxics
since 2010 and the work efforts that are needed to
reduce toxics in the Basin to benefit human health
and the health of fish and wildlife.
Background on the
Columbia River Basin
The Columbia River Basin is one of the world's great
river basins in watershed size, river volume, and
environmental and cultural significance. Covering
nearly 260,000 square miles - approximately the
size of the state of Texas - the Columbia River Basin
is the nation's sixth largest watershed. The Basin
drains portions of Canada's British Columbia province
and seven U.S. states, but mostly Montana, Idaho,
Washington, and Oregon. Within its boundaries lies
multiple tribal reservations and 45 million acres of
tribaliy co-managed land. The Basin contains great
geographic and land-use diversity, including alpine
peaks, forested slopes, semi-arid grassland and
rangeland, arable agricultural land, and an extensive
estuary. From its source in the Canadian Rockies,
the mainstem Columbia River flows more than
1,200 miles to the Pacific Ocean. Its average annual
flow - 270,000 cubic feet per second - makes it
the United States' fourth largest river by discharge.
Significant tributaries include the Kootenay, Pend
Oreille, Spokane, Okanagan, Yakima, Snake, John Day,
Deschutes, Willamette, and Cowlitz Rivers.
Toxic Contaminants
Are a Priority Focus
The Basin's aquatic ecosystem is critical to supporting
the fish and wildlife and over 8 million people who
reside within the watershed and depend on its
resources for their health and livelihood. There is
concern about the health of the Basin's aquatic
ecosystem and the potential risk to human health due
to the presence of toxics found in the fish, wildlife,
water, and sediment.
Toxic contamination is a human health risk and key
environmental justice issue for tribal people and other
high fish-consuming populations. Columbia River
salmon and steelhead runs were once the largest in
the world. As many as 16 million fish would return
annually to spawn in the Basin. Columbia River tribes
have depended on native fish species, including
(but not limited to) salmon, steelhead, sturgeon,
and lamprey for thousands of years for spiritual,
cultural, and nutritional sustenance. Human activities
including hydrologic modifications for flood control
and power generation, industry, urban development,
mining, and agricultural practices have affected fish
spawning and rearing habitat, blocked or impeded
fish passage, and contributed toxic contaminants that
have impaired water quality. As a result, many of the
Basin's salmon and steelhead stocks are threatened
or endangered. The Columbia River Basin Fish and
Wildlife Program does not include actions to assess or
reduce toxics. Many scientists believe that recovery of

salmon, steelhead, and other fish populations cannot
be achieved without reducing toxics in water and
sediment.
In 1992, the Environmental Protection Agency's
(EPA) National Study of Chemical Residues in Fish
found bioaccumulative toxics in Columbia River Basin
fish tissue. Recognizing the historic importance of
fish in the diets of tribal people and the potential
human health impacts of toxics, the Columbia River
Inter Tribal Fish Commission (CRITFC) and EPA
developed the 1994 Fish Consumption Survey of
the Umatilla, Nez Perce, Yakama, and Warm Springs
Tribes of the Columbia River Basin which found that
tribal people were consuming 9 to 12 times more
fish than the average US resident. EPA and CRITFC
followed up that study with the Columbia River
Fish Contaminant Study 1996-1998 which found 92
pollutants in fish from 24 tribal fishing sites, including
contaminants with human health impacts such as
polychlorinated biphenyls (PCBs), dioxin, mercury,
dichlorodiphenyltrichloroethane (DDT), and furans.
Convened in 2005, the Working Group has played
an important role in facilitating information sharing
and collaboration between entities and individuals
throughout the Basin. The Working Group led
the development of the 2009 Columbia River
Basin State of the River Report for Toxics which
addressed four contaminants: DDT, PCBs, mercury,
and polybrominated diphenyl ethers (PBDEs) and
the risk they pose to people, fish and wildlife,
and highlighted successful efforts to reduce those
contaminants. The 2009 report was followed by the
2010 Columbia River Basin Toxics Reduction Action
Plan, which identified sixty-one actions needed across
five categories: increasing public understanding to
reduce toxics; increasing toxics reduction actions;
conducting monitoring to identify sources and
reduce contaminants; developing a regional research
program; and developing a shared data management
system. In 2014, the Working Group released its
Strategy for Measuring, Documenting, and Reducing
Chemicals of Emerging Concern, providing an
outline for a research and monitoring strategy and
a characterization of the impacts of chemicals of
emerging concern on human health, aquatic life and
terrestrial wildlife.

Columbia River Basin
Restoration Act-Clean
Water Act Section 123
On December 9, 2016, Congress passed the Columbia
River Basin Restoration Act (CRBRA) as part of the
Water Resources Development Act (WRDA), also
known as the Water Infrastructure Improvements for
the Nation (WIIN) Act of 2016. The WRDA was signed
into law by the President on December 16, 2016.
The legislation focuses on the U.S. portion of the
Columbia River Basin including the States of Oregon,
Washington, Idaho, and Montana. The newly created
Section 123 of the Clean Water Act (CWA) directs
EPA to establish a Columbia River Basin Restoration
Program which includes a Working Group that is
representative of states, tribal governments, industry,
and other entities. Clean Water Act Section 123
also directs EPA to develop a voluntary, competitive
grant program for "environmental protection and
restoration programs throughout the Basin." The
CRBRA is the first legislation to officially designate
the national importance of Columbia River Basin
restoration. Many entities in the Basin who recognized
that the current Columbia River Basin Fish and
Wildlife Program has not addressed toxics reduction
supported the legislation as a critical opportunity to
better assess and reduce toxic contaminants in water
and fish.

The Government Accountability Office (GAO)
began an investigation of Columbia River Basin
restoration efforts in early 2017. Released in August
2018, GAO's final report, Columbia River Basin:
Additional Federal Actions Would Benefit Restoration
Efforts, recommended that EPA develop a program
management plan for implementing the CWA Section
123 Columbia River Basin Restoration Act with a
schedule of actions to be undertaken by EPA. In
January 2019, Congress appropriated $1 million to
EPA for implementation of the Act.
Representative Working Group and
Competitive Grant Program
EPA is working to implement the Columbia River Basin
Restoration Program including the establishment of a
representative Working Group and the development
of a competitive grant program. CWA Section 123
directs the EPA Administrator to convene a Columbia
River Basin Restoration Working Group. Participation
in the Working Group is voluntary and invited entities
may decline to participate. EPA plans to launch a
voluntary, competitive grant program in the Fall of
2019 following the Act's requirements on federal cost
share and geographic allocations within the Basin.
Eligible grant recipients are expected to include
states, tribal governments, regional water pollution
control agencies and entities, local governments,
nongovernmental organizations, and soil and water
conservation districts.
Status Report
In October 2018, the Columbia River Toxics Reduction
Working Group agreed to revisit the 2010 Columbia
River Basin Toxics Reduction Action Plan and work
with EPA to provide a status report on major
accomplishments in toxics reduction, monitoring,
and prevention across the Basin as well as significant
needs for future work to reduce and assess toxic
contaminants. This report reflects a summary of
interviews conducted between April and June 2019.
Appendix A includes the interview methodology and
the names of individuals, and their respective entities,
that were interviewed for this report.
Summary of Major Accomplishments
Since the release of the 2010 Action Plan, Working
Group partners and other interested parties noted the
following major successes and accomplishments:
¦	Columbia River Toxics Reduction Working Group
¦	Passage of the Columbia River Basin Restoration
Act, Clean Water Act Section 123
¦	Safer Chemical Alternatives
¦	Pollution Prevention Programs
¦	Oregon's Pesticide Stewardship Partnerships
¦	Performance-Based Agricultural Certification Programs
¦	Regulatory Actions
¦	Site-Specific Clean-up Actions
Columbia River Toxics Reduction Working Group
Major accomplishments include the 2009 Columbia
River Basin State of the River Report for Toxics,
the 2010 Columbia River Basin Toxics Reduction
Action Plan, and regular check-ins with state, tribal,
and federal executives in the Basin to reaffirm a
commitment to toxics reduction. In 2014, the Working
Group and EPA developed the Columbia River Strategy
for Measuring, Documenting and Reducing Chemicals
of Emerging Concern. Another key success was the
2014 Pesticide Stewardship Partnership Workshop in
Walla Walla, Washington. Agricultural producers, the
U.S. Department of Agriculture's National Resources
Conservation Service, industry representatives and
state, tribal, and federal leaders assembled to share
information on pesticide reduction best management
practices (BMPs). In partnership with the Northwest
Power and Conservation Council, the Working Group
produced the 2018 Polycyclic Aromatic Hydrocarbons
(PAHs) Toxic Contaminant Story Map as a pilot
mapping tool to display PAH monitoring data in water
and sediment throughout the Basin, educate the

public on aquatic and public health impacts of PAHs,
and identify how PAHs get into the environment
through the burning of coal, oil, gas, wood, and other
carbon-based materials.
Passage of the Columbia River Basin Restoration
Act, Clean Water Act Section 123
The passage of the Act was a major accomplishment
as a demonstration of political commitment to
address water quality concerns, particularly toxic
contamination, in the Basin. The Legislation provides
a framework for future funding of toxic reduction,
monitoring, and outreach actions.
Safer Chemical Alternatives
Green chemistry seeks to design chemicals and
processes that are safer, healthier, and more
sustainable. Certification programs such as EPA's
Safer Choice, Washington Department of Ecology's
(Ecology) Quick Chemical Assessment Tool, and similar
chemical hazard tools developed by Northwest Green
Chemistry and other organizations help consumers
and businesses select less toxic alternatives to
traditional products. State agencies in Oregon and
Washington have leveraged their buying power by
establishing institutional procurement policies that
require the purchase of environmentally preferable
products. In Idaho and Washington, green chemistry
programs are reducing toxics in high school
classrooms.
Pollution Prevention Programs
Partners throughout the Basin are working with
residents and local businesses to identify sources of
toxics, reduce toxic runoff or discharges and prevent
the use of toxic materials through voluntary technical
assistance programs, such as Idaho's pollution
prevention programs, Ecology's Local Source Control
Program, and Missoula County's HazWaste Days.
Idaho Department of Environmental Quality
coordinates collection and diversion events for
household hazardous waste, safely disposing of
motor oil, mercury, pharmaceuticals and other
materials that would otherwise be dumped into
landfills or down storm or sewer drains. The Missoula
Valley Water Quality District runs similar hazardous
household waste collection events as a critical
pollution prevention measure to protect the region's
shallow, sole source drinking water aquifer. Through
partnerships with local governments, Ecology's
Local Source Control Program provides free, on-site
assistance to help businesses in Spokane and Clark
Counties resolve pollution issues by reviewing spill
prevention practices, providing stormwater best
management practices, and locating recycling or
disposal resources.
Oregon's Pesticide Stewardship Partnerships
Through the Oregon Pesticide Stewardship
Partnership Program, state agencies partner with
landowners and growers, watershed councils
and other natural resource organizations, tribal
governments, and soil and water conservation
districts to reduce pesticide levels while measuring
improvements in water quality. The Program works
on a voluntary basis with farmers to implement
proper storage, handling procedures and application
methods for pesticides, and safely dispose of unused
agricultural chemicals.

Performance-Based Agricultural
Certification Programs
Voluntary performance-based certification programs,
such as Salmon Safe, have proven effective in
improving water quality by promoting soil and water
conservation and reducing the discharge of toxics,
such as actively used and legacy pesticides, from
agricultural lands.
Regulatory Actions
In 2018, the Oregon Department of Environmental
Quality updated its 1200-Z general industrial
storm water permits in accordance with a settlement
agreement with Columbia Riverkeeper and Northwest
Environmental Defense Center. The revised permits
provide special protections for impaired waterbodies,
increase the required reporting frequency, and
establish procedures to investigate if more stringent
numeric permit limits for certain toxic stormwater
pollutants are feasible.
Through the work of the Spokane River Toxics
Reduction Task Force, six additional watersheds
have Total Maximum Daily Loads (TMDLs) for toxics:
Mission Creek (a tributary to the Wenatchee River),
(Photo by Jason Faucera)
Lake Chelan, and the Yakima, Okanagan, Walla Walla,
and Palouse Rivers. TMDLs can guide toxics reduction
efforts and permitting limits to attain water quality
standards that protect people, fish and wildlife.
Site-Specific Clean-up Actions
Ecology's Toxics Cleanup Program remediates soils at
contaminated sites to prevent the release of toxics.
Additional investigation and site characterization
activities were required by Ecology at two sites
adjacent to the mainstem Columbia River in Klickitat
County-the Goldendale Aluminum Plant and the
Burlington Northern Santa Fe site near Wishram,
Washington.
Progress was made at three sites in Montana under
EPA's Superfund Program's National Priorities List
for cleanup and remediation actions. Following the
removal of the Milltown Dam at the confluence of
the Blackfoot and Clark Fork Rivers in 2008, more
than 2 million cubic yards of toxic reservoir sediments
contaminated by historic mining activities were
removed. The Smurfit-Stone Mill near Missoula was
proposed for listing; and the Columbia Falls Aluminum
Company site near Glacier National Park was added
to the National Priorities List. Both these sites have
undergone initial site characterization and risk
assessment.
Summary of Significant
Needs Looking Forward
As the Columbia River Basin Restoration Program
is implemented, the following significant needs to
address toxics were identified. These needs reflect
the geographic, political, and land use diversity of the
Basin and the multiple strategies required to address
the sources of toxic contaminants found throughout
the Basin:
¦	Systematic, Coordinated Monitoring
¦	Agricultural Best Management Practices
¦	Green Infrastructure
¦	Pollution Prevention Programs
¦	Public Education and Outreach
¦	Leadership and Resources
Systematic, Coordinated Monitoring
Monitoring of water, sediment, and biota is critical
to identify sources of toxic contamination, detect
trends through time and space, and evaluate the
effectiveness of management actions on a short- and
long-term basis. There is a need to work toward a
6

-------
continuous, system-wide program for priority toxic
contaminants and to monitor for contaminants of
emerging concern (e.g. nanoparticles, glyphosate,
pharmaceuticals, and per- and polyfluoroalkyl acids
(PFAS), among others). In portions of the upper basin
affected by historic and active mining operations,
there is a need to monitor for heavy metals and other
toxics to identify sources and prioritize site-specific
cleanup activities.
Agricultural Best Management Practices
Irrigated and non-irrigated agriculture can degrade
water quality by contributing soil contaminated with
pesticides and toxic organic compounds to nearby
waters in irrigation return flows and runoff from
fields. Agricultural best management practices can
be used to improve water quality, often with the
added benefits of conserving water and soil and
improving soil fertility. Successful programs, such as
Oregon's Pesticide Stewardship Partnership Program
and performance-based farm certifications, should
be increased throughout the Basin to include new
partner organizations, crop types, and agricultural
practices.
Yakima Basin Agricultural
BMP Success Story
The implementation of best management practices
in Washington's Yakima River Basin to control soil
erosion and reduce pesticide runoff was a major
success. The work was the result of a collaborative
partnership between Washington Department of
Ecology, Yakima Valley growers, water purveyors,
local conservation districts, and the Confederated
Tribes and Bands of the Yakama Nation. The goal of
the project was to lift the fish advisory for DDT on the
Yakima River within 20 years.
To prevent the discharge of contaminant-laden
sediment in irrigation return flows — a major source
of DDT - local growers upgraded to drip irrigation
on 8,000 acres of hops and installed vegetated
buffer strips to keep soil on the fields. Following
implementation of the BMPs, suspended sediment
loading to the Lower Yakima River decreased 67 to
80 percent during the irrigation season and total DDT
concentrations in fish were reduced 30 to 85 percent.
Fish advisories for DDT on the Yakima River were lifted
5 years after the project started - 15 years earlier than
their initial goal!
2019 Status Update:
Columbia River Basin Toxics Reduction

-------
Green Infrastructure
In urban landscapes, the installation of green
infrastructure has proven to be effective in reducing
the discharge of contaminated runoff from impervious
surfaces such as roads and roofs. Local governments
and industries should expand the use of bioswales,
constructed wetlands, planter boxes, downspout
disconnection and other methods to infiltrate toxic-
containing runoff before it reaches local waterways.
Pollution Prevention Programs
Preventing pollution is essential to reducing actively
used toxics. Local source control and pollution
prevention programs should be expanded to identify
and address toxics before they reach waterways.
Examples of successful programs include pesticide
collection events, pharmaceutical take-back programs,
and no-cost technical assistance.
Public Outreach and Education
There is a need to raise awareness about toxics
contamination in the Basin, both to encourage
behavior change and to educate people about the
impacts of toxics on their health. Due to higher
exposure rates to toxics and the associated increased
health risks, there is a need for increased outreach
to high fish consuming populations, including many
tribal members, about the presence of toxics in the
river and fish tissue. Additionally, public workshops to

Conclusion
This report provides a summary of input from the
Working Group partners on the most successful
actions in reducing and assessing toxics since 2010
and priority efforts still needed to reduce toxics in
the Basin. Working Group partners identified current
resources as insufficient for the efforts needed to
reduce toxics in the Basin to protect people, fish and
wildlife.
The passage of the Columbia River Basin Restoration
Program, Clean Water Act Section 123, anchors the
strong commitment by many partners to a geographic
and holistic approach to improving water quality
and ecosystem health in the Basin. EPA is committed
to work with a collaboration of state, tribal, local,
and federal government agencies; business and
industry; non-governmental organizations; private
citizens and others; in the years ahead to reduce toxic
contamination in the Columbia River Basin.
engage farmers about the contribution of toxics from
agricultural fields and how to implement BMPs could
be expanded in the Basin.
Leadership and Resources
Reducing toxics contamination in the Columbia
River Basin will require political leadership, effective
coordination, and resources. In the past, federal,
state, tribal and regional executives convened on
a periodic basis to reaffirm their commitment to
working together to reduce toxics to protect human
health and the Columbia River's ecosystem. This level
of leadership is greatly needed to ensure successful
implementation of the CRBRA as work efforts move
forward. Section 123 describes a broad coalition of
states, federally recognized tribes, local governments,
soil and water conservation districts, electric,
water and wastewater utilities, non-governmental
organizations, landowners and private citizens, and
the Lower Columbia Estuary Partnership, in addition,
partnerships must also be strengthened among
federal agencies and regional entities such as the
Northwest Power and Conservation Council and tribal
consortia who represent tribal governments across
the Basin.
