Annex 4: Areas of Concern

The purpose of this Annex is to restore water quality and ecosystem health in Areas of Concern.

Areas of Concern (AOCs) are geographic areas in the Great Lakes that were identified in the mid-1980s because water quality and ecosystem health had been severely degraded by human activities to the point that beneficial uses were impaired. Restoring these areas not only benefits the local community, it also contributes to improving water quality and ecosystem health throughout the Great Lakes. Forty-three locations were formally recognized as AOCs by Canada and the United States pursuant to the 1987 Protocol to the Canada-United States Great Lakes Water Quality Agreement: 12 in Canada, 26 in the United States and five binational AOCs that are shared by the two countries.

The environmental degradation within AOCs is primarily a legacy of the past caused by industrial activities, agriculture, urban and rural runoff, municipal wastewater effluents, land-use planning and practices on urban and rural lands. These past practices resulted in degraded water quality, contaminated river and lake sediment, and severely impacted fish and wildlife populations and habitats.

Working with community members and local governments, Canada and Ontario are implementing Remedial Action Plans (RAPs) to restore beneficial uses within the AOCs. Considerable progress has been made and, by 2010, three of the Canadian AOCs had been fully remediated and officially delisted (no longer deemed to be an AOC): Collingwood Harbour in 1994, Severn Sound in 2003, and Wheatley Harbour in 2010. Two additional Canadian AOCs have had all recommended remedial actions completed and have been recognized as being in recovery: Spanish Harbour in 1999 and Jackfish Bay in 2011. Environmental monitoring is continuing to confirm restoration of water quality and ecosystem processes.

In the remaining Canadian and binational AOCs, continued efforts are needed to complete implementation of the RAPs to restore ecosystem quality. This Annex includes initiatives that directly support the restoration and protection of environmental quality and beneficial uses in AOCs. This will contribute to the long-term goal of delisting the remaining AOCs and ensuring that environmental improvements achieved through the AOC process are sustained.
