Environmental groups warn of proposed coal plant discharge into Missouri River

Environmental groups are sounding the alarm about a proposal by a plant near Sioux City to put water that's run through coal ash into the Missouri River. They say it would contain dangerous heavy metals that need to stay out of the river. The plant is George Neal Energy Center North in Sergeant Bluff, Iowa. The idea is to put coal ash leachate in the Missouri River. That's water that's run through coal ash.
