Site descriptionSeminole Electric Cooperative, Inc.'s Seminole Generating Station is a 1,276-MW coal-fired power plant with two units that began operating in 1984. The plant is located near the St. John's River just outside of Palatka, Florida in Putnam County. Waste from the plant is disposed of in an unlined flue gas desulfurization landfill, two unlined storm water 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.
