The Illinois Environmental Protection Agency will have a public hearing on a proposal by Dynegy Midwest Generation, LLC to stabilize the Middle Fork River at the retired Vermilion Power Station near Oakwood. The hearing will be Tuesday, March 26, at Danville Area Community College. The state has also opened up public comment on the proposal until April 25. Dynegy has applied for a permit to construct a 1,900-foot long wall of rock on the river. Construction would require excavation of the river bottom up to seven feet deep, and replacing river sediments with 20,240 cubic yards of rock materials.
