The treated effluent from etangs Mingan is discharged into the St. Lawrence River, which flows into the Gulf of St. Lawrence and eventually the Atlantic Ocean. The St. Lawrence River is a major waterway supporting diverse aquatic life, including fish species such as Atlantic salmon and sturgeon, and is an important migratory corridor for birds.

The plant discharges into the St. Lawrence River, a major river that drains into the Gulf of St. Lawrence and the Atlantic Ocean. The St. Lawrence River supports a rich ecosystem, including fish populations like Atlantic salmon and lake sturgeon, and provides critical habitat for migratory waterfowl. The downstream environment includes the Gulf of St. Lawrence, an ecologically sensitive marine area that sustains fisheries and marine mammals.
