coal ash

The northwest Indiana utility NIPSCO is working to repair a seawall on the site of its Michigan City coal plant. Activists worry the wall could fail, sending coal ash into Trail Creek and Lake Michigan.

Coal ash is the waste leftover from burning coal — which can contain toxic heavy metals like mercury, cadmium and arsenic. Flooding could damage the caps that cover the coal ash ponds, causing the ash to leak out and pollute waterways nearby.

The environmental group alleges the Eagle Valley Generating Station in Martinsville discharges untreated wastewater into a stretch of the White River, just upstream of Martinsville’s municipal wells.

Power providers in Kentucky and Indiana say some federal restrictions on coal ash and greenhouse gas pollution should end.

New rules from the Environmental Protection Agency will extend federal regulations of coal ash at active and inactive coal-burning plants and disposal sites throughout the country.

Coal ash was used as construction fill in hundreds of properties in the Town of Pines in Northwest Indiana.

According to the American Coal Ash Association, the use of coal ash as fill went up by 40 percent from 2020 to 2021 following several years of declines.

Scientists, lawmakers and business leaders joined together to talk about how to better manage Indiana’s water.

Groups concerned about coal ash pollution are asking the governor to veto a bill that wouldn’t let Indiana set stricter coal ash rules than federal ones.

AES Indiana converted its Eagle Valley plant from coal to natural gas seven years ago. But there is still coal ash at the site and monitoring data shows it’s leaching toxic heavy metals into the groundwater — like arsenic, boron, lithium, mercury and molybdenum.
