Snapshot

Clifty Creek Power Plant has 6 groundwater monitoring wells, 5 of which have been polluted above federal advisory levels based on samples collected between January 14, 2010 and November 11, 2014. Groundwater at this site contains unsafe levels of manganese, arsenic and boron.

Site description

Indiana-Kentucky Electric Corporation's Clifty Creek Power Plant is located on the Ohio River in Madison, Indiana. The plant has six coal-fired electric generating units capable of generating 217 MW each. According to the site's 2015 fugitive dust plan, the plant uses around 3 million tons of coal per year.

The plant has three coal ash disposal areas: a residual waste landfill, a boiler slag pond, and a landfill runoff collection pond. The landfill contains boiler slag, fly ash, gypsum, and other coal combustion waste from the plant. The landfill runoff collection pond was formerly used for fly ash disposal but now collects runoff from the landfill and surrounding area.

The U.S. Environmental Protection Agency (EPA) in 2009 rated the landfill as having a significant hazard dam due to potential impacts to the Ohio River if the dam should fail. Clifty Creek Power Plant is on EPA's list of potential damage cases, indicating that its landfill has likely impacted groundwater.
