The plant discharges into the Loire estuary, a major river system that drains into the Bay of Biscay and the Atlantic Ocean. The estuary is a dynamic ecosystem that supports diverse aquatic life, including migratory fish such as salmon and eels. Its coastal location requires careful management of nutrient and pollutant loads to prevent eutrophication and protect marine habitats.
