The International Joint Commission was established by the 1909 Boundary Waters Treaty of the United States and Canada. The treaty recognizes that each country is affected by the other's actions in the lake and river systems along their common border. Its primary purpose is to prevent and resolve disputes concerning these shared waters. In 1972, the governments of the United States and Canada signed the Great Lakes Water Quality Agreement. In 1978, the governments signed a new Agreement which included additional commitments to rid the Great Lakes of persistent toxic substances. Its purpose is to restore and maintain the chemical, physical and biological integrity of the waters of the Great Lakes basin ecosystem. IJC was given the responsibility to assess and evaluate the governments' programs and progress under the 1972 Agreement and assist in its implementation. In 1987, the governments signed a Protocol that included a commitment to report on progress and calling on IJC to review Remedial Action Plans being developed and implemented for the 42 identified Areas of Concern in the Great Lakes basin. The Commission has initiated a process for examining progress in specific Areas of Concern and open lake waters, called the Status Assessment process. The St. Marys River Area of Concern is the second such assessment.
Introduction
Remedial Action Plans and Areas of Concern
The goal of Remedial Action Plans (RAPs) is to restore and protect beneficial uses in 42 identified Areas of Concern (AOCs) within the Great Lakes basin. AOCs are geographic areas where human activities have caused or are likely to cause impairment of beneficial uses or the area's ability to support aquatic life. Table 1 presents, pursuant to Annex 2 of the Great Lakes Water Quality Agreement (Agreement), the 14 possible beneficial use impairments, their status as documented in the Stage 1 RAP for the St. Marys River AOC, the International Joint Commission's (IJC) Stage 1 review comments, and recommendations based on these comments. The United States and Canada (the Parties), in cooperation with state and provincial governments, agreed to develop and implement RAPs in a 1987 protocol to the Agreement. Each RAP is to embody a systematic and comprehensive ecosystem approach to restoring and protecting beneficial uses and serve as an important step toward virtual elimination of persistent toxic substances. Further, the Parties, in cooperation with state and provincial governments are to ensure that the public is consulted in all actions undertaken pursuant to Annex 2 of the Agreement.
The IJC is to review and comment on RAPs during three stages of development: when the definition of the problem has been completed; when remedial and regulatory measures are selected; and when monitoring indicates that impaired beneficial uses have been restored. In 1996, after more than ten years of reviewing and assisting in development of RAPs, and expressing concern with overall progress in development and implementation of cleanup and prevention strategies in some AOCs, IJC adopted a new initiative to examine progress toward restoration of beneficial uses by initiating status assessments in individual AOCs in an attempt to enhance the restoration process.
The St. Marys River AOC represents an ideal opportunity for the Parties to engage in a truly binational exercise in environmental restoration. Recommitment by the agencies to a partnership effort focused toward achieving implementation is required. The recent signing of the Four Agency Framework of Roles and Responsibilities for the Implementation of the Detroit River, St. Clair River and St. Marys River Shared Remedial Action Plans is symbolic of this needed recommitment. In particular, the leadership section of the Four Agency Framework details actions that are necessary in the St. Marys AOC.
The Status Assessment Process
Status assessments are intended to: examine progress toward restoration and protection of beneficial uses, assess program implementation relative to remedial and preventive actions; and identify and make recommendations on specific activities that could be taken to overcome obstacles and make measurable progress in restoring uses in the area. These status assessments are not comprehensive environmental audits, but assessments of ongoing efforts and activities of the responsible governments and organizations. Objectives of the status assessment process include collecting information on and transferring successful methods and experiences among different AOCs, and facilitating constructive interaction among various agencies and organizations that may have limited opportunity to exchange ideas.

The St. Marys River Area of Concern
Setting and Sources of Contamination
The binational St. Marys River Area of Concern extends from Whitefish Bay at a line drawn between Point Iroquois (Michigan) and Gros Cap (Ontario) to lines from Quebec Bay (Ontario) and Humbug Point (Ontario) on the St. Joseph Channel and respectively, Point Aux Frenes (Michigan) and Hay Point (Ontario) on the West Neebish Channel (OMOE and MDNR 1992). There are about 15,000 people living in the Sault Ste. Marie, Michigan and its vicinity and approximately 81,000 people living in the Sault Ste. Marie, Ontario and its vicinity.
The St. Marys River AOC has two major industrial dischargers. Algoma Steel Corporation and the St. Marys Paper Company are both located in Sault Ste. Marie, Ontario. These dischargers have represented major sources of contaminants to the St. Marys River. Emissions from Algoma Steel Corporation are also a source of the persistent toxic substances, benzene and polycyclic aromatic hydrocarbons (PAHs). There is no major industry on the U.S. side although the Cannelton Industries Superfund site is located on the grounds of a former tannery.
Sault Ste. Marie, Ontario operates two water pollution control plants (WPCP). Of these, the East End WPCP has primary treatment technology. Sault Ste. Marie, Michigan operates one wastewater treatment plant. There are sanitary sewer overflows and combined sewer overflows in the Ontario-side and Michigan-side, respectively. In addition, small treatment plants serve the communities of Richards Landing and Hilton Beach on the Ontario side of the St. Marys River. A third plant for the community of Echo Bay is under construction.
A recent report by the governments of Canada and Ontario (1998) states "Fish advisories for walleye, longnose sucker, and chinook are due to mercury and PAHs from discharges such as Algoma Steel, St. Marys Paper, and the East End WPCP". This statement conflicts with a comment from the governments of Canada and Ontario regarding the Commission's Status Assessment. The comment letter (Governments of Canada and Ontario, 1998) states "The sport fish advisories in the St. Marys River are primarily due to mercury contamination and we believe that local sources within the AOC are not responsible". At this time, it remains unclear which statement is accurate.
The Stage 1 RAP documented contaminated sediment problems on the Ontario side from the Algoma Slip to sites downstream including Bellevue Marine Park, Little Lake George and Lake George. On the U.S. side, contaminated sediment problems were noted at the Cannelton Industries Superfund site, Lake Nicolet and Munuscong Lake. Current information regarding the level of contamination is unavailable for Ontario sites except results from a 1995 survey of Bellevue Marine Park were made available in February 1998 in a report undertaken on behalf of the Ontario Ministry of Environment (OMOE) entitled "1995 Survey of St. Marys River Benthos in the Vicinity of Bellevue Marine Park" (Kilgour and Morton 1998). This report states "The study demonstrated that the St. Marys River in the vicinity of Bellevue Marine Park is still significantly contaminated with metals, oil and grease, total petroleum hydrocarbons, PAHs and nutrients." The report also noted "Contaminant concentrations have generally been reduced from 1987 . . ." No sampling was undertaken in 1995 regarding stations further downstream from the industrial sources. Accordingly, the current status of these downstream sites is not possible to discern. The Stage 1 RAP did note that "Complete recovery of the benthic communities occurs in the lower section of Lake George, 24 kilometers (15 miles) downstream from the industrial discharges."
The dischargers noted above contribute to concerns regarding impacts on aquatic life and human health. The existence of a local source for atmospheric loadings of persistent toxic substances is an additional concern due to these loadings' contribution to the human health concerns or the impairment of beneficial uses within the AOC. Boom and Marsalek (1987) studied the accumulation of PAHs in the snowpack of Sault Ste. Marie, Ontario over a 2.5 month period and determined about 90 kg/year of PAHs would fall in the area annually. No recent estimates of PAH loading in Sault Ste. Marie, Ontario are available.
Human Health Considerations
Citizens have expressed concern regarding emissions from industry, consumption of environmentally contaminated fish, beach closures, and potential exposure to bacteria and other contaminants through the use of raw river water for drinking water. Possible human health effects due to local sources of air pollution are a transboundary concern within the AOC. PAHs and benzene in emissions are of particular interest to the IJC. A recent report by Canada and Ontario (1998) cited local dischargers as sources of mercury. The IJC's Stage 1 RAP review stated "Human health concerns in the AOC are numerous and go beyond the use impairments that have been identified for this RAP." Possible neurobehavioral effects from consuming environmentally contaminated fish have been documented in the Great Lakes Basin (Johnson et al. 1997, Lonky et al. 1996, Jacobson et al.1984).
St. Marys River Assessment History
IJC's first examination of water quality conditions in the St. Marys River took place in 1912 in response to a request from the governments of the United States and Canada to examine the extent and causes of pollution in the Great Lakes. Water quality problems related to raw sewage were identified in the St. Marys River and other connecting channels in the basin. Although problems relating to raw sewage have been substantially corrected in most areas and water borne disease epidemics eliminated, other problems, such as the presence of persistent toxic substances, have been subsequently identified in the St. Marys River and in other areas of the Great Lakes basin. These problems became the subject of the 1978 Agreement and the 1987 Protocol.
A Stage 1 RAP (problem identification) for the binational St. Marys River Area of Concern was submitted for IJC review on May 11, 1992. Identified sources of pollution were: contaminated sediment; point source discharges from municipal and industrial sources including sanitary and combined sewer overflows; and non point sources of pollution from such sources as urban storm-water runoff including air deposition of toxic substances. Environmental issues of concern included: changes in fish community structure; loss of fish and wildlife habitat; impact on biota from impaired sediment quality; and adverse impacts of exotic species. IJC's review comments were submitted to the Parties on August 10, 1993. The current status of RAP implementation as defined by Environment Canada and the Ontario Ministry of Environment is presented in Table 2. Reservations regarding the accuracy of Table 2 in regard to the status of beneficial use impairments have been expressed by representatives of other implementing agencies and the BPAC.
Current Status Assessment
This current status assessment of the St. Marys River AOC was conducted between May 1997 and October 1998 and included consultation between IJC Commissioners and citizens, representatives of government agencies, local industries, municipalities, Native Americans/First Nations, and the Binational Public Advisory Council. In addition to this public consultation, IJC's Science Advisory Board conducted a public meeting concerning issues of scientific relevance to the development and implementation of the RAP.
Table 2. Environment Canada and Ontario Ministry of Environment RAP Implementation Status
An examination was conducted in the following areas: funding; institutional structure; roles of the Parties, jurisdictions and other sectors; and public consultation. This evaluation examines activities within the AOC that foster restoration of beneficial uses and is not confined to activities conducted as part of the RAP.
Findings: The IJC's Status Assessment examined the successes and obstacles in the restoration process for the St. Marys River AOC. Examples of both are detailed below in order to document and promote successful activities and help overcome the obstacles.
Notable Successes: Numerous advances toward restoration of the St. Marys River AOC were recognized during the Status Assessment. Notable successes are detailed below:
Obstacles to AOC Restoration and IJC Recommendations
Obstacles to a timely restoration of beneficial uses in the St. Marys River AOC were noted during the Status Assessment process. Presented below are key obstacles and IJC recommendations.
Ineffectual Coordination Between Agencies: Existing coordination mechanisms across the Canada/United States border have not resulted in a satisfactory degree of communication in this binational AOC. Frequent staff changes including at least seven changes in the Ontario RAP coordinator position have undoubtedly hindered coordination efforts. Recent activities related to preparation of the Stage 2 RAP have raised additional questions. Concerns have been voiced by agency and BPAC representatives in regard to content of the proposed outline for the Stage 2 RAP document. As outlined in the Four Agency Framework (Four Agency Framework) of Roles and Responsibilities for the Implementation of the Detroit River, St. Clair River and St. Marys River Shared Remedial Action Plans (Environment Canada et al. 1998), OMOE and Environment Canada have the primary responsibility for the administration of shared activities for the St. Marys RAP. Data gaps and concerns over certain environmental problems have lingered since preparation of the Stage 1 RAP document. In fact, neither the Michigan Department of Environmental Quality nor the BPAC supported the submission of the Stage 1 RAP to the IJC for review and comment.
The IJC understands that the St. Marys River BPAC outlined its concerns especially in regard to completion of a contaminated sediment management plan and the continued release of raw sewage and resultant impacts in a letter dated June 15, 1998. Concern regarding OMOE's activities in the AOC was expressed as long ago as 1992. The IJC is concerned that a commitment to an expedient completion of a Stage 2 document may, in reality, hinder the long-term process of restoring the beneficial uses in the St. Marys River AOC. The IJC believes that time and effort spent now to fully consider and respond to comments of other agencies will represent an investment toward future implementation of remedial actions. In an August 10, 1998 letter, Environment Canada and Ontario Ministry of Environment state "The Canadian agencies have since 1995 developed a good working relationship with Michigan Department of Environmental Quality and U.S. EPA". However, based on IJC observations, there was a serious question regarding the presence of effective coordination. For example, the IJC observed that in responding to the opportunity to comment on its Status Assessment, no obvious coordination between agencies in Canada and the United States occurred. Subsequent to receiving comments from the agencies, a representative of the IJC met with representatives from Environment Canada, Michigan Department of Environmental Quality, and Ontario Ministry of Environment to review their comments and current status of their relationship. Although there may be disagreement between the agencies on the past status of their interactions, it is clear that subsequent to the commencement of this assessment and signing of the Four Agency Framework in the spring of 1998, active staff-level interaction has been occurring between Michigan and Ontario regarding the development of the Stage 2 RAP and other AOC issues. The IJC strongly encourages the agencies to continue to build and sustain these relationships.
Recommendation:
Inadequate Consultation with Citizens: Canadian agencies indicate that they have provided, on the average, $35,000 (Cdn.) annually since 1988 toward the purpose of public consultation. The outcome of these expenditures remains unclear. Numerous lead agency staffing changes and an apparent lack of oversight have contributed to problems regarding consultation with the public. As the IJC has previously noted, stable, locally-based agency support (IJC 1998) is the most preferred staffing option. Personnel involved in AOC restoration activities which forego this approach must be aware that extraordinary effort may be needed to achieve adequate consultation with the public. Numerous lead agency staffing changes have contributed to problems regarding consultation with citizens. According to members of the BPAC, there is not only a low level of public awareness regarding the AOC and goals for restoration, but there is a perception of abandonment of citizens' interests by the government agencies. This perception may be based on the limited contact by lead agency personnel over the past four years. Representatives of key industries have not participated in the BPAC for several years. It is unclear if lead agency personnel have taken any action to ensure acceptance and encouragement of participation by industry on the BPAC. The situation regarding public consultation appears to have improved during the Status Assessment process. It remains unclear if necessary resources are devoted to public consultation. Recently, the U.S. Environmental Protection Agency provided a $15,000 (U.S.) grant to assist the BPAC and it has made an additional $10,000 grant available to the BPAC through the Michigan Department of Environmental Quality.
Regardless of the level of support that has been provided, the IJC, during its Status Assessment, heard a litany of complaints regarding the lack of agency attention to environmental concerns of citizens. Annex 2 of the Agreement requires consultation with citizens in regard to all actions undertaken pursuant to the Annex. Informing citizens of actions taken cannot be regarded as consultation. Too little effort has been devoted to the important task of public consultation. Establishing or regaining the public trust in the AOC may prove to be a lengthy and time-consuming process.
Recommendation:
Need to Quantify Environmental Benefits of Remedial Actions: Several significant remedial actions have already been undertaken in the AOC and it appears that no reader-friendly tracking of success/progress that could be readily available to local residents has been developed and implemented. During the Status Assessment, it became apparent that government and industry successes and developments were not being transferred to interested citizens, agencies, elected officials, etc. The lack of information flow across the border was especially obvious. In particular, this shortcoming appears a detriment to the encouragement of responsible industry actions. If significant improvements to their operations that result in the enhancement of environmental conditions are not adequately recognized, can they be expected to eagerly undertake expensive improvements in the future? Tracking and reporting of these activities could be undertaken more cost-effectively if they are linked to ongoing public consultation efforts. Since government has a regulatory or oversight role, this function might best be accomplished by an independent local entity.
Recommendation:
Monitoring of Environmental Conditions: Questions and concerns exist in regard to contaminated sediment conditions and emissions to the atmosphere by local industry. Bacteria levels due to sanitary sewer overflows in Sault Ste. Marie, Ontario, and resultant human health concerns in regard to the use of raw river water for drinking are ongoing issues. Due to limited available data, the current status of these concerns is difficult to ascertain. It is also unclear how previous staffing reductions in the Sault Ste. Marie office of OMOE will affect future monitoring efforts.
When the Stage 1 was completed, benthic community recovery was noted 24 kilometers (15 miles) downstream from the industrial discharges. Due to the lack of an ongoing sediment quality monitoring program, the present extent of benthic community impairment is unknown. The most recently completed sampling focussed only on the Bellevue Marine Park vicinity. Because of the lack of available information, the extent of recovery in regard to benthic community degradation could not be confirmed during the Status Assessment process. This deficiency, unless corrected, will also preclude tracking of future environmental improvements that may accrue due to planned remedial actions.
Recommendation:
Sewage Treatment Plant Upgrades: Planning and Funding: During its examination of infrastructure needs and improvement plans for Sault Ste. Marie, Ontario, and Sault Ste. Marie, Michigan, the IJC found planning to be uncertain in regard to upgrading the East End WPCP from primary treatment technology to secondary treatment technology. Discussion with OMOE regarding this situation yielded a statement that talks of funding an upgrade were premature until flows to the plant were controlled. The overflow of raw sewage is a concern of local citizens and the IJC. Plans for controlling excess flows and upgrading the East End plant should be fully explored through inter-agency discussions and the public could be informed of the costs and benefits of this undertaking.
Recommendations:
Involvement of Native Americans/First Nations: While undertaking this status assessment, IJC found no evidence of specific outreach programs directed at the most impacted subset of the AOC's population, the Native American/First Nation population. Representatives of Native Americans/First Nations expressed to the IJC their perception of abandonment by agencies. According to the BPAC, Aboriginal lands in Michigan and Ontario continue to be affected by the release of raw sewage during wet weather flow conditions.
Recommendation:
Concluding Remarks
There are unresolved issues and opportunities for the restoration of beneficial uses in the AOC even though the geographic area and number of responsible parties are well defined. In addition to specific actions, fuller public and industry involvement and consultation are needed and achievable. The cooperation that appears to be developing between agencies should be extended by specifically designed programs in a binational context to engage citizens of the region and specific interests such as industry, fishing community and aboriginal peoples. As the IJC has witnessed in other AOCs, budget cutbacks, staffing reductions and changes, and changing priorities have seriously impacted the RAP process. The IJC notes these changes often occur without publicity or consultation. Despite these challenges, there are notable advancements toward environmental restoration in the AOC. And yet, even these advancements have gone without notice or publicity.
The St. Marys River AOC is an ideal opportunity for a truly binational exercise in environmental restoration. Recommitment by the agencies to a partnership effort focused toward achieving implementation is required. The recent signing of the Four Agency Framework can provide impetus toward achieving this recommitment. In particular, the leadership section of the Four Agency Framework details actions that are needed in the St. Marys AOC. Promised necessary actions include:
needs and gaps; and
