A cascade of coal ash, dirt and mud fell into the shore of Lake Michigan yesterday after a large section of bluff collapsed beside the We Energies Oak Creek Power Plant in Milwaukee County, Wisconsin. It is unknown how much coal ash fell from the pile, but the spill left behind a debris field about 120 yards long, the Milwaukee-Wisconsin Journal Sentinel reports.
"Based on our land use records it is probable that some of the material that washed into the lake is coal ash," We Energies spokesman Barry McNulty told the Journal Sentinel. "We believe that was something that was used to fill the ravine area in that site during the 1950s. That's a practice that was discontinued several decades ago."
