The Illinois Environmental Protection Agency has announced a public comment period and a public hearing notice on a Dynegy plan to stabilize the Middle Fork River at the retired Vermilion Power Station near Oakwood.

The Illinois Supreme Court is being asked to settle a fight between two of the state’s environmental regulators. At issue is whether certain waste disposal sites should have to do groundwater testing.

The Illinois Environmental Protection Agency is asking the Attorney General’s office to temporarily shut down a Chicago-area chemical plant. The agency says that plant is releasing an illegal amount of cancer-causing fumes into the air.

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.

The Illinois Environmental Protection Agency has issued a violation notice to Vistra Energy Corporation for alleged violations of the Illinois Environmental Protection Act at the Vermilion Power Station near Oakwood, Illinois. In May the Illinois EPA conducted a stream survey of the Middle Fork Vermilion River near three coal ash ponds owned by Vistra, and found water with “heavily stained reddish-brown discoloration” seeping from the riverbank. The violation notice says the seeps were discharging into the river, staining sediment and rocks, and creating “offensive conditions in the Middle Fork.”
