Seminole Electric Cooperative, Inc.'s Seminole Generating Station is a 650-MW coal-fired power plant that began operating in 1984. The plant is located near the St. John's River just outside of Palatka, Florida. Waste from the plant is disposed of into an unlined flue gas desulfurization landfill, two unlined stormwater runoff ponds, and three lined process wastewater ponds. In 2004, Seminole Electric Cooperative constructed a groundwater collection system to capture contaminated groundwater from deep and shallow aquifers underlying the landfill.
Seminole Generating Station is among the U.S. Environmental Protection Agency's list of potential damage cases, indicating that it has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
