The plant's coastal location within 10 km of the lake underscores the importance of effective treatment to protect water quality and aquatic life.

The plant discharges into the Lake Superior basin, one of the world's largest freshwater lakes. Lake Superior's cold, deep waters support a unique ecosystem including lake trout, whitefish, and other native species. The watershed is ecologically sensitive, with wetlands and forests that filter runoff and provide habitat. Protecting water quality is critical for downstream communities and the overall health of the Great Lakes system.
