Long known to be contaminating groundwater, the coal ash ponds at Colstrip Power Plant are on a leaked EPA list of 160 contaminated ponds for which it wants to see closure plans. The state has its own coal ash cleanup program separate from the EPA. The state of Montana hasn’t taken that on,” said Sarah Seitz, DEQ’s go-to officer on Colstrip ash ponds. In November 2020, DEQ selected a cleanup plan for the ash ponds that served the oldest of Colstrip’s four units. Environmentalists say they were pleased to see the Colstrip ash ponds on the EPA’s list.
