Site description

General James M. Gavin Power Plant, originally owned by American Electric Power and sold to Lightstone Generation LLC in 2017, is in Cheshire, Ohio along the Ohio River in Galla County. The power plant is one of the largest coal-fired plants in the nation with two generating units capable of generating 1,300-MW of electricity each (2,600-MW total). AEP constructed the plant in 1974 and renovated it in the mid-1990s.

The plant currently disposes of coal ash in a residual waste landfill and a separate bottom ash pond. The residual waste landfill, which contains flue gas desulfurization wastes including fly ash, covers around 255 acres and fills three valleys. The plant's bottom ash pond is located on the south side of the plant and covers nearly 85 acres. A third disposal area northwest of the currently active landfill, Stingy Creek Dam, is currently closed but received fly ash until 1994. The U.S. Environmental Protection Agency categorized both the active landfill and bottom ash pond as having high hazard dams. In 2002, American Electric Power bought the town of Cheshire for $20 million dollars in order to resolve numerous citizen complaints about air pollution from the plant. Gavin Power Plant’s Fly Ash Reservoir, Residual Waste Landfill and Bottom Ash Complex are all regulated under the CCR-rule.
