Environmental groups criticize Ameren's plan to cap legacy coal ash sites rather than excavate the toxic material
from St. Louis Post-Dispatch
At Ameren's coal-fired power plants, decades of leftover ash fills massive storage ponds acres in size and dug up to 100 feet deep into the flood plains along major rivers — leak-prone sites that critics say pollute groundwater and adjacent waterways. But despite concerns and objections, that's where Ameren's legacy coal ash will remain, the St. Louis-based utility announced Aug. 30, outlining a plan to cover its ash ponds while leaving the material in the ground and continuing to monitor groundwater.
