The costs of closing a coal ash waste site
Who pays and for how long?

At Dynegy's coal ash ponds at the Vermilion Power Station, toxic pollution is already impacting groundwater and the Middle Fork River. The company is preparing several options for completely closing the site, including removing the coal ash, or simply capping the ponds and leaving the coal ash in place. Both options have costs; the question is who pays how much, and when.

Since 1955 the Vermilion Power Plant has been storing toxic coal ash in three ponds next to the Middle Fork Vermilion River near Oakwood, Illinois

Loose regulations allow coal ash to threaten river
Middle Fork River at risk from Dynegy coal ash ponds

Each year thousands of families boat down the Middle Fork branch of the Illinois Vermilion River below an embankment that holds back 3.3 million cubic yards of toxic coal ash sludge stored in three large ponds. Coal ash pollution is leaching into the river, and the riverbank is eroding under the ponds. We examine what's a stake in this investigative report.

Residents, environmentalists worry about a possible collapse

Environmentalists and community members in Vermilion County have expressed deep concern over the pollution from toxic chemicals seeping from large coal ash ponds into the Middle Fork River in Vermilion County. But engineering experts warn there may be a greater risk posed by the collapse of the riverbank holding back more than 600 million of gallons of toxic coal ash.
