Dynegy’s Coal Ash Threat
Dynegy’s Coal Ash Threat
Dynegy owns three coal ash impoundments in the floodplain of the Middle Fork of the Vermilion River in Vermilion County, Illinois. These pits are just upstream from Kickapoo State Park, and 12 miles from the City of Danville's riverfront development project. They contain a mix of coal ash materials (including fly ash, bottom ash, boiler slag, and other materials) with different chemical compositions (because of different types of coal burned over the power plant’s lifetime).
Two of the three pits are unlined and are leaking coal ash pollutants into the groundwater and the Middle Fork River. The third sits over mine voids created by prior mining, raising questions about its long-term stability.
There are already visible seeps along the bank, and detectable impacts in the water and aquatic life. This means that heavy metals in coal ash are currently placing the Middle Fork and adjacent groundwater at risk. A recent study by the Illinois Natural History Survey has documented elevated levels of coal ash contaminants in aquatic organisms downstream from the site.
What is Coal Ash?
Coal ash is a byproduct of burning coal. It contains toxic substances like mercury, arsenic, selenium, cadmium and chromium. When these materials leach into surface and groundwaters, they contaminate drinking water and natural ecosystems. Coal ash pollutants can cause cancer as well as damage to nervous systems and other organs, especially in children. Coal ash also can also harm and kill wildlife, especially fish and other water-dwelling species.
A Disaster Waiting to Happen
Because all three coal ash pits lie within the floodplain of the river, floodwaters and high water tables are a threat to their foundations and structural integrity. During a flood, the power of the river cuts new channels, and the embankments of the pits are eroding from the river. Steel gabions, constructed in 1978 to support these embankments, are crumbling as leachate from the ponds is corroding the metal structure and wastewater is draining into the river.
If just a little over 1% of Dynegy’s coal ash entered the river, it would be comparable to the volume of Duke Energy's 2014 Dan River spill that sent coal ash 70 miles downstream.

A breach of these pits could send millions of cubic yards of toxic ash down the river much like recent catastrophes in Tennessee and North Carolina. The 2014 Duke Energy spill in North Carolina sent 46,000 cubic yards of toxic waste into the Dan River, which traveled 70 miles downstream. A spill such as this on the Middle Fork could leave massive cleanup costs to taxpayers, and Illinois’ only National Scenic River and adjacent wildlife and recreation areas would be devastated. The City of Danville is purchasing land along both sides of the river for its new riverfront project, and would be severely impacted by a spill.
Dynegy closed its Vermilion coal-fired power plant in 2011. Now, as part of its closure plan, Dynegy wants to cap these pits and leave the toxic waste in the floodplain. In order ensure the long-term protection of the Middle Fork and avoid massive expenditures, complete removal of this dangerous waste from the floodplain is essential. The Illinois EPA is currently reviewing Dyngey's plan for closing its toxic coal ash pits. It's important that we urge Illinois Governor Rauner to call the IEPA and tell them to require Dynegy to remove its coal ash from the floodplain, and place it in properly-constructed, lined basins on their property, far from the river.
