Iowa Environmental Groups Sue State Over Coal Ash Pollution Permits
Environmental groups in Iowa, including the Iowa Environmental Council (IEC), Environmental Law and Policy Center (ELPC), and Sierra Club, have filed a lawsuit against the Iowa Department of Natural Resources (DNR). The lawsuit challenges the DNR's approval of permits that allow hazardous disposal practices at the Ottumwa coal ash landfill. This landfill, associated with the Ottumwa coal-burning power plant co-owned by Alliant Energy and MidAmerican Energy, is accused of polluting Iowa's groundwater and waterways with toxic heavy metals such as arsenic, mercury, and lead. These pollutants pose significant health risks to local communities, fish, and wildlife. The groups are demanding that the DNR enforce federal discharge limits adopted in 2024, which require facilities to stop discharging coal ash leachate as soon as possible. However, the current permits lack a timeline for compliance.
