Executive Summary
As the Great Lakes Binational Toxics Strategy (GLBTS) broadens its scope from a focus on the Level 1 substances to
encompass substances of emerging concern, the governments and stakeholders have acknowledged the need to
modify the way they both operate and report on progress.
In light of the evolving mandate of the GLBTS, the Parties have also agreed to institute reporting and operational
changes in order to ensure the continued effectiveness and success of the Strategy:
To improve the tracking of progress in reducing legacy and emerging substances, the Parties have agreed to
prepare a Status Report once every two years, with a more robust formal GLBTS Progress Report in alternate years.
This change takes effect now, with this 2008 GLBTS Status Report replacing the 2008 annual progress report. The
2009 GLBTS Biennial Progress Report will be available in 2010.
To improve the efficiency and ensure the continued effectiveness of the Strategy, the frequency of Workgroup and
Stakeholder Forum meetings and the means by which they meet have been changed.
The GLBTS and its stakeholders have accomplished much over the past decade to continually improve the health
of the Great Lakes. As it adapts to a broadened scope, the GLBTS will remain an open and transparent process,
building on its tradition of continuous multi-stakeholder engagement, and continue to pursue the systematic
sharing of information that empowers both voluntary and regulatory activities.

Introduction
Signed in 1997 by Environment Canada (EC) and the United States
Environmental Protection Agency (US EPA), the Great Lakes Binational
Toxics Strategy (GLBTS, or Strategy) established U.S. and Canadian
challenge goals for 12 Level 1 persistent toxic substances, and targeted
a list of Level 2 substances for pollution prevention measures. Over the
past 11 years, the governments of Canada and the United States, along
with stakeholders from industry, academia, state/provincial and local
governments, Tribes, First Nations, and environmental and community
groups have worked together to achieve these goals. Thirteen of the
original seventeen challenge goals have been met, and significant
progress has been made toward the remaining four. Under the Strategy,
EC and US EPA also agreed
to consider additional
substances that may present
threats to the Great Lakes
ecosystem. This status
report describes recent
progress and recognizes
that the challenge ahead
for the GLBTS is to identify
and address potential new
chemical threats to the
Great Lakes Basin.
The Level 1 substances consist
of: mercury, polychlorinated
biphenyls (PCBs), dioxins and
furans, hexachlorobenzene
(HCB), benzo(a)pyrene (B(a)P),
octachlorostyrene (OCS),
alkyl-lead, and five pesticides:
chlordane, aldrin/dieldrin, DDT,
mirex, and toxaphene.
A Changing GLBTS
EC and US EPA recognize the accomplishments of the GLBTS to reduce and eliminate Level 1 substances in the
Great Lakes. While Level 1 substances have declined in the Great Lakes over the past several years (Table 1), a
variety of new substances of emerging concern have been detected, including brominated flame retardants
and perflurochemical compounds (GLBTS 2006 Annual Progress Report, Chapter 8, Environmental Indicators of
Progress). In light of these detections, in 2008, the GLBTS
Integration Workgroup decided to shift the focus of the
GLBTS to substances of emerging concern. In addition,
the Integration Workgroup decided to reduce the
frequency of face-to-face meetings, to consider making
greater use of electronic means of communications such
as teleconferences and webinars, and to modify the way
it reports on progress.
The GLBTS is a voluntary forum in which a variety of
stakeholders collaborate to share information and
devise mitigation strategies to address persistent toxic
substances which impact the Great Lakes Basin. As the
GLBTS moves forward to address substances of emerging
concern, EC and US EPA seek to retain its key attributes:
an open and transparent process, continued multi-
stakeholder engagement, and the systematic sharing of
information to empower both voluntary and regulatory
actions.
GLBTS Annual Reports
As the GLBTS transitions from a focus on the
Level 1 substances to substances of emerging
concern, EC and US EPA have decided, with
concurrence from stakeholders, to change the
reporting mechanisms for the GLBTS.To lessen
the burden of publishing the traditional GLBTS
progress report annually, the governments will
now prepare a formal progress report once
every two years and a less formal status report
in alternate years. This change takes effect now,
with this 2008 GLBTS Status Report replacing the
2008 annual progress report. The 2009 GLBTS
Biennial Report will be available in 2010.
-------
Substance/Sector Group
In September 2007, EC and US EPA commenced the GLBTS Substance and Sector Groups. Recognizing the
mutual interests of the Substance and Sector Groups, the two workgroups were subsequently combined into
one Substance/Sector workgroup to more effectively undertake the exploration of substances of emerging
concern, which may present threats to the Great Lakes ecosystem, and to explore mitigation strategies and other
management options that GLBTS stakeholders might pursue to address these substances.
Rationale
Consistent with the objectives of the Great Lakes Water Quality Agreement (GLWQA), and the Strategy, the
objective of the Substance/Sector Group is to protect and ensure the health and integrity of the Great Lakes
ecosystem through the identification and prevention of the release of toxic substances into the Great Lakes. Under
the Strategy, EC and US EPA are directed to consider substances of emerging concern that may pose threats to the
Great Lakes Basin ecosystem, and to explore mitigation strategies, where warranted.The Strategy also challenges
the Parties to consider"whether new substances which present threats to the Great Lakes ecosystem should be
considered for inclusion on the Level 1 or 2 lists."
Activities
Terms of reference for the Substance/Sector Group have been outlined in a draft Guide to the Substance and Sector
Groups. The group has developed a Binational Framework for Identifying Substances of Potential Threat to the Great
Lakes Basin. In consultation with stakeholders, several substances profiles are being developed to evaluate this
Framework. The Substance/Sector Group meets on a quarterly basis.
The following Substance/Sector Group meetings were held in the past year:
November 30,2007 teleconference
June 2-3,2008 meeting, Burlington, Ontario
August 7,2008 teleconference
September 25,2008 meeting, Chicago, Illinois
December 2-3, 2008 meeting, Chicago, Illinois
In addition, the Substance/Sector Group reported its progress and discussed future directions at GLBTS Integration
Group Meetings.
Next Steps
The Substance/Sector Group currently meets on a quarterly basis. In conjunction with Canadian and U.S. national
programs, the Parties plan to select a number of candidate substances to evaluate through the Framework
and, in consultation with stakeholders, consider potential
management options, as warranted. In the future, the
group intends to develop management actions to address
substances of emerging concern that may be undertaken by
the Parties and stakeholders within the GLBTS.
Future efforts of the Substance/Sector Group are expected
to align with work being undertaken by other existing Great
Lakes programs, such as ongoing monitoring and surveillance
efforts, and the GLWQA, which is currently under review with
amendments on the horizon.The Substance/Sector Group's
work will also help inform a renewed 2010 Canada-Ontario
Agreement Respecting the Great Lakes Basin Ecosystem (COA). Waterfallon the Cypress Riveri Ontario. Photo courtesyof Tim

Changes to the Integration Workgroup
and Stakeholder Forum
The Integration Workgroup will reduce its schedule of quarterly face-to-face meetings to semi-annual meetings,
and a Stakeholder Forum will be convened annually in conjunction with an Integration Workgroup meeting.
Greater use of telecommunications will be considered by both.
Progress of the Level 1 Workgroups
Level 1 workgroups will continue to interact on an as-needed basis, through the use of video conferences and
webinars. Progress toward the Level 1 challenge goals is presented in the table on page 3. Additional activities
undertaken by the Level 1 workgroups in the past year are described below.
Mercury Workgroup
The Mercury Workgroup contributed to the
development of a Great Lakes Mercury in Products
Phase-Down Strategy sponsored by the Great Lakes
Regional Collaboration (GLRC). Implementation of the
strategy has begun in the Great Lakes states ("Great
Lakes Mercury in Products Phase-Down Strategy"
19 June 2008 ). I n
addition, a new GLRC-sponsored strategy has been
initiated, the Great Lakes Mercury Emission Reduction
Strategy. Input for this Strategy will be solicited
from stakeholders on an ongoing basis through the
Mercury Workgroup. Mercury Workgroup activities
have decreased in the past year as both Canada and
the United States have met their challenge goals. In
place of regular workgroup meetings, the Mercury
Workgroup plans to periodically organize and/or
sponsor larger science and policy conferences. It
will continue to share information on efforts related
to reducing and tracking mercury releases in the
environment, in addition to focusing increased
attention on global releases.
PCB Workgroup
In September 2008, EC published new PCB regulations in Canada Gazette 11 that are expected to help Canada meet
its challenge goal of a 90% reduction of high-level PCBs in service. Regulation requires that equipment containing
high-level PCBs and low-level PCBs in sensitive locations be phased out by December 2009. Equipment containing
low-level PCBs in all other locations must be phased out by December 2025.The rule also limits the maximum
duration of storage of PCBs by generators to 1 year, 1 year at an authorized transfer station, and 2 years at disposal
facilities.
The PCB Workgroup will continue to seek commitments to reduce PCBs through PCB reduction commitment
letters and other PCB phase-out efforts, and to publicize voluntary achievements in PCB reduction.The workgroup
has developed a software tool to assist companies in evaluating the costs and benefits of PCB use, storage, phase-
out and elimination programs.The tool is expected to be freely available to the public. US EPA is considering ways
to more broadly communicate its availability.
Mercury Collection Programs
In Canada, the Clean Air Foundation operates two
voluntary mercury collection programs: Switch Out and
Switch the'Stat. Since 2001, as a result of participation
by more than 600 automotive recyclers across Canada,
the Switch Out program has collected more than
200,000 mercury-containing switches from end-of-life
vehicles (-170 kg of mercury). The Switch Out program
recovered approximately 31 kg of mercury from more
than 36,500 switches in the past year. The Switch the
'Stat program has collected more than 17,100 mercury-
containing switches from thermostats since its launch in
April 2006, 72% of which were recovered in the past year
(-31 kg of mercury).
In the United States, Bowling Green State University
(BGSU) in Ohio has operated an Elemental Mercury
Collection and Reclamation Program since 1998. The
free program collects and recycles uncontaminated
elemental mercury that is present in a variety of devices,
including thermometers, thermostats, and mercury
switches, as well as bulk mercury. To date, the program
has collected over 23,000 Ibs of elemental mercury for
recycling.
-------
To prioritize remaining opportunities for PCB source reductions, the PCB Workgroup has begun to collect and
assess information on sources of PCBs other than PCB-containing transformers and capacitors. The workgroup
is also investigating the status of facilities that purchased PCBs from Monsanto in the 1970s, in an effort to
determine the fate of the PCBs and to identify sites that may warrant investigation or maybe in need of clean-up
(e.g., abandoned sites with PCB contamination or equipment).
Due to the progress achieved, the PCB Workgroup has reduced its number of face-to-face meetings from two to
one per year. With the new Canadian PCB regulation in place, the workgroup believes that it would be valuable for
Canada to share their PCB phase out knowledge and experience at this meeting.
Dioxin/Furan Workgroup
In December 2007, the Dioxin/Furan Workgroup decided to move to inactive status. Both Canada and the United
States have met their goals for dioxins/furans, reducing releases by approximately 90% to 28 g TEQ in Ontario
and 1,422 gTEQ nationwide in the United States.Through a Decision Tree exercise, the workgroup identified ten
of the top twelve sources as low priorities for the GLBTSto address. Most sources are being managed by existing
programs. Recognizing that historical sources of dioxins/furans remain in the environment and that they can
continue to be released from small sources, the Dioxin/Furan Workgroup co-chairs will continue to track progress
on dioxins/furans through release inventories and environmental monitoring data.The co-chairs may reactivate
the workgroup, if warranted, as new issues arise. The co-chairs will also investigate potential opportunities to
reduce agricultural waste burning and other poorly characterized sources of dioxins/furans. The largest source of
quantified dioxin releases remaining in both countries is household garbage burning.The Burn Barrel Subgroup
continues to address the use of burn barrels and other open burning issues, but now reports to the HCB/B(a)P
Workgroup.
HCB/B(a)P Workgroup
US EPA and Environment Canada support several programs that help reduce releases of HCB and B(a)P from diesel
engines, residential wood stoves and fireplaces, scrap tire piles, steel mills, and other sources. The workgroup is
evaluating the use of coal tar sealants as a source of B(a)P in the United States, and will begin to review the use of
coal tar sealants in Ontario. The workgroup has also updated release inventories for sources of HCB and B(a)P.The
most recent inventory of HCB sources in Ontario totals 13 kg (29 Ibs) of releases, a relatively low level of release,
but another 8 kg (18 Ibs) must be reduced to meet Canada's HCB challenge goal. Approximately 60,000 Ibs of
B(a)P are released to the Great Lakes region annually. Major sources of B(a)P in Ontario include residential wood
combustion, use of creosote-treated railway ties, and cokemaking in the steel manufacturing sector (although
release estimates for this sector are under review). The workgroup will continue its efforts to improve the accuracy
of the United States and Canadian HCB and B(a)P emission inventories to ensure that all significant emission
sources have been identified and integrated, including a study of emissions from certified wood stoves and new
studies to measure the impacts of wood smoke and other air pollutants. The workgroup will continue to pursue
emission reduction activities from significant B(a)P source sectors. The workgroup will also continue to support
actions that impact HCB releases to the Great Lakes Basin, such as full life-cycle management of PCP-treated
wood products, modeling of HCB to the Great Lakes from North American sources, solicitation of voluntary HCB
reductions from chemical companies, and the efforts of the Burn Barrel Subgroup. The HCB/B(a)P Workgroup has
also reduced the number of face-to-face meetings from two to one per year.
Burn Barrel Subgroup
The Burn Barrel Subgroup continued efforts to reduce emissions from open garbage
burning. Consultation with Great Lakes states, tribes, and Province of Ontario indicated
that there was value in continuing to address the burn barrel issue and to consider
broadening the scope of the subgroup's efforts to include other pollutants and related
uncontrolled combustion issues.The subgroup held three teleconferences during
2008 and developed a scoping document that identifies objectives and activities to
implement under the expanded scope of the subgroup. The subgroup will continue to photo courtesy of Patrick Atagi
hold regular conference calls to share information and identify issues for further action. American Chemistry Council
-------
Progress Toward the Long-Range
Transport Challenge
Under the Strategy, EC and US EPA committed to assessing atmospheric inputs of Strategy substances to the
Great Lakes by evaluating and reporting on the contribution and significance of long-range transport of Strategy
substances from worldwide sources. An example of research efforts conducted in support of this challenge is EC's
Emission Inventory and Multiple Pathways Modeling ofHCB to the Great Lakes from North American Sources, which
used an atmospheric transport model and emission inventories. The major findings of this study are summarized
below.
(1) Given that HCB strongly persists in the environment, and that North American industrial emissions (reported by
US EPA and EC and in the literature) accounted for a lower HCB level in the atmosphere than the air concentrations
measured throughout the 2000s, the main source of HCB emissions in North America can be attributed to the past
use of HCB as a fungicide in agriculture.
(2) Given the very long half life of HCB in air and the long period that has elapsed since its ban for agricultural use,
air concentrations of HCB across North America have become fairly uniform and stable, and may be a significant
source of HCB to the Great Lakes environment.
(3) On an annual basis, the Midwest United States (specifically states adjacent to the Great Lakes) and Ontario
sources have been the leading contributors to atmospheric and Great Lakes basinwide HCB levels. Sources in the
Northwest United States were the second major source of HCB over the Great Lakes, followed by sources in the
Canadian Prairies and the Southwest United States.
(4) Computation of the HCB soil/air fugacity ratio indicated that strong volatilization took place from the spring to
autumn in most regions of the United States, whereas Canada (except for southern Ontario) remained a receptor
of HCB deposition.
(5) In 2000, Lake Michigan received the largest dry deposition of HCB, followed by Lakes Superior, Huron, Erie, and
Ontario. For the same year, Lake Michigan also received the greatest wet deposition, followed by Lakes Erie, Huron,
Superior, and Ontario (Figure 1). Both dry and wet deposition to the lakes, in 2001, were considerably lower than
those in 2000, but followed almost the same deposition sequence of lakes as those in 2000.
(6) The highest HCB loading due to the net gas (water/air) exchange in 2000 was found over Lake Superior,
followed by Lakes Erie, Michigan, Huron, and Ontario. For 2001, the largest gas exchange flux was found in Lake
Erie (Figure 2). Overall, the results clearly indicate that the Great Lakes had become sources of HCB in the 2000s,
where volatilization dominates the net gas exchange.

-------
The sink to source reversal of HCB in the Great Lakes likely suggests that lakes have been undergoing a "self-
cleaning" process since the 2000s. While this long-range transport study identified sources of HCB that could
be contributing to the Great Lakes levels, it was not an attempt at identifying human or biota effects. However,
decreasing depositions combined with volatilization dominating water/air exchange implies that more HCB are
evaporating from lake waters, a positive trend with respect to the Great Lakes fisheries and drinking water. By
contrast, the lands in the upper Great Lakes ecosystem, namely in northern Ontario where temperatures are lower,
are still HCB receptors.
Progress in Remediating
Contaminated Sediment
In 20071, approximately 960,000 yd3 of contaminated
sediment were remediated from eleven U.S. sites and one
Canadian site in the Great Lakes Basin. Remedial action
was initiated for the first time in 2007 at three U.S. sites and
one Canadian site. Five U.S. sites completed their remedial
actions in 2007.Three U.S. sites, each under a different
cleanup authority, continued to make progress on their
remedial actions. Highlights of sediment assessment and
remediation activities undertaken in the Canadian and U.S.
Great Lakes Basin are presented below.

Bay of Quinte (Trent River) -As part of the ongoing monitoring work to assess sediment quality,
elevated levels of dioxins and furans were found in sediment at the mouth of the Trent River in 2001. An
Ecological Risk Assessment completed in 2007 predicted that there is negligible risk to piscivorous wildlife
and fish exposed to the contaminated sediment. As such, monitored natural recovery was chosen as the
preferred management option for this site. Source track down is continuing in the area.
Wheatley Harbour - An Ecological Risk Assessment undertaken in 2007 concluded that there is negligible
risk of PCB effects to piscivorous wildlife in the Muddy Creek wetland. Therefore, the Wheatley Harbour
Implementation Team recommended that no further action is required prior to delisting this Area of
Concern.
Niagara River (Lyons Creek, East & West) -Arsenic-contaminated sediment from Lyons Creek West was
excavated (300 cubic metres) in the summer of 2007 and placed in a secure landfill facility. Management
options are being developed in consultation with various stakeholders to address PCB-contaminated
sediments in Lyons Creek East and Lyons Creek West (the watercourse is bisected by the Welland Canal).
U.S. Update
In 2008, the US EPA's Research Vessel Mudpuppy assisted in the assessment of ten contaminated sediment
sites in the Great Lakes Basin.
Allied Paper, Inc./Portage Creek/Kalamazoo River, Kalamazoo, Michigan - A Time Critical Removal
Action (TCRA) was implemented in April 2007 by Georgia-Pacific and Millennium Holdings contractors
as a result of agreements negotiated by the two companies along with US EPA Superfund, Michigan
Department of Environmental Quality, and Natural Resource Trustees. Approximately 37,000 yd3 of PCB-
contaminated sediment were dredged from the Kalamazoo River in a 1.2 mile area near Plainwell, Ml.
PCB-contaminated sediments were sent to a TSCA permitted disposal facility and solid waste landfills in
Michigan.

• Ashtabula River, Ashtabula, Ohio - The Ashtabula River Great Lakes Legacy Act project was a
collaborative effort between the US EPA and the Ashtabula River Partnership (represented by the
Ashtabula City Port Authority). In 2007, over 435,000 yd3 of PCB-contaminated sediment were dredged
utilizing a 12-inch hydraulic cutterhead dredge. Production dredging was followed by cleanup dredging
utilizing an 8-inch hydraulic dredge outfitted with the Vic Vac® suction system. Dewatered sediments
remained in geotextile tubes within theTSCA permitted landfill facility constructed as part of the
remediation project, and will be covered and capped in 2009.
Tittabawassee River, Reach D & Reach O, Midland, Michigan - In July 2007, the US EPA and the
Dow Chemical Company signed two consent orders to address elevated levels of dioxin-contaminated
sediment within the Tittabawassee River. Approximately 12,000 yd3 of soft bottom deposits were
removed from Reach D using a GPS-guided hydraulic dredge system. Sediment was pumped via pipeline
to a containment facility for dewatering. Reach O was segregated into five removal management units
separated by sheet piling. Over 16,000yd3 of sediment were dry-excavated from Reach O. All sediments
were disposed of at Dow's Salzburg Landfill.
The chart below presents the cumulative volume of sediment remediated in the United States since 1997. US
EPA and its partners have now remediated more than 10% of the estimated volume of sediments requiring
remediation in the U.S. Great Lakes Basin.The Great Lakes Legacy Reauthorization Act of 2008 was signed into law
on October 8,2008, thereby extending funding for two years at a level of $54 million per year.
