Download Data

Keystone Generating Station has 11 groundwater monitoring wells, 2 of which have been polluted above federal advisory levels based on samples collected between December 22, 2015 and October 12, 2017. Groundwater at this site contains unsafe levels of cobalt and radium.

Site description

Reliant Energy’s Keystone Generating Station is located in Indiana County, PA along the banks of Crooked Creek. The Keystone Plant began operating in 1967 and is capable of producing 1,872 MW from its two coal-fired units. The site contains two ash ponds and one onsite landfill. The Keystone plant ranks 10th in the nation for worst polluters of mercury according to the 2010 EIP report and 1st in annual toxic emissions as per the EPA’s 2009 Toxic Release Inventory. The EPA reported that the Keystone Generating Station released a total of 15.5 million pounds of the “most toxic air pollutants” as can be seen in their data and reports here: 2009 Toxic Release Inventory. The Keystone Plant Ash Ponds and Landfill are both regulated under the CCR rule. You can find the industry-reported data here. For more information on the adverse effects of coal-ash groundwater pollution, and information on Keystone Plant emissions, see EIP’s 2019 National Coal Ash Report.
