Snapshot

Thomas Hill Energy Center has 6 groundwater monitoring wells, 3 of which have been polluted above federal advisory levels based on samples collected between August 21, 2016 and September 12, 2017. Groundwater at this site contains unsafe levels of sulfate, lithium, cobalt and arsenic.

Site description

Associated Energy Cooperative’s Thomas Hill Energy Center is located in Randolph County, MO adjacent to the 1.5 billion gallon Thomas Hill Reservoir. Thomas Hill has been in operation since 1966 and currently operates two coal-fired units that generate a combined 1,135 MW. Thomas Hill Energy Center is one of the few plants in the country that burns “clean coal,” a refined form of coal known for releasing more NOx emissions than coal’s unrefined form. Thomas Hill operates an onsite Ash Pond System that is regulated under the CCR rule. You can find the industry-reported data here. For more information on Thomas Hill Energy Center, see EIP’s 2019 National Coal Ash Report.
