Remedial Action Plan for the St. Lawrence River Area of Concern

St. Lawrence River Remedial Action Plan

The St. Lawrence River at Cornwall, Akwesasne, and Massena was designated as an Area of Concern (AOC) in 1985 by the governments of Canada and the United States in cooperation with the International Joint Commission (IJC). Beginning in the 1970s, the IJC identified 42 problem areas or Areas of Concern in the Great Lakes where waters were considered heavily polluted. Of these, 17 were located in Canada and 5 were located in boundary waters shared between the U.S. and Canada. The most heavily impacted areas of the St. Lawrence River at Cornwall, Akwesasne and Massena forms one of these 5 bi-national AOCs. A Remedial Action Plan process was initiated in 1986 for the St. Lawrence River (Canadian side) and was developed by what was then Environment Canada, the Ontario Ministry of Environment and Energy, the Ontario Ministry of Natural Resources, and the Mohawk Council of Akwesasne in conjunction with the St. Lawrence River Public Advisory Committee. The goal was to characterize the water quality issues and identify specific remedial actions needed to improve the health of the River.

Oversight Committee

St. Lawrence River Restoration Council

The St. Lawrence River Restoration Council (SLRRC) was formed in 1998 in order to oversee and address identified ecological challenges or Beneficial Use impairments (BUIs) that have been identified within the St. Lawrence River Area of Concern at Cornwall and Akwesasne. Over the years, SLRRC membership has been made up of federal and provincial government agencies, the Mohawk Council of Akwesasne, Saint Regis Mohawk Tribe, Raisin Region Conservation Authority (RRCA), the municipalities of Cornwall and South Glengarry, the River Institute and other local environmental groups, and industry.
