"Indiana’s biggest utility can’t make its customers pay more than $200 million in costs related to cleaning up its toxic coal ash, according to a ruling Thursday from the Indiana Supreme Court.
That’s because Duke Energy did not follow the correct process to do so, the Court said.
Much of Duke’s electricity comes from burning coal, which produces coal ash. This ash contains a dangerous mix of heavy metals and toxic chemicals such as arsenic, boron, lead and mercury. Sampling shows these toxins have been leaching into groundwater near sites around Indiana where the ash was dumped."
