The Meramec River supports diverse aquatic life and is an important recreational resource for the region. The plant's operations help protect water quality in this ecologically sensitive watershed.

The plant discharges into local streams that drain to the Meramec River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Meramec River watershed supports diverse aquatic species and is a key habitat for freshwater mussels and fish. Protecting water quality in this basin is critical for downstream ecosystems and recreational uses.
