The plant's proximity to the coast (within 10 km) means its discharge can influence the river's water quality and downstream ecosystems.

The plant discharges into the St. Lawrence River, which drains into the Gulf of St. Lawrence and the Atlantic Ocean. The river supports diverse aquatic life, including fish species such as lake sturgeon and walleye, and is an important migratory corridor for eels and salmon. The plant's coastal location means its effluent can affect the river's nutrient balance and downstream estuarine habitats.
