GAO Reports on What Happens to All the Coal We Burn

And its not a pretty picture

In the flurry of Senate news, I overlooked the fact that the Government Accountability Office (GAO) issued a report last Friday on coal ash storage and disposal in the U.S. as requested by the Senate Environment and Public Works Committee and Committee on Oversight and Government Reform in the wake of last Christmas's devastating spill at a TVA facility in Kingston, Tennessee.

This earlier post on some testing EPA has ordered at an AEP coal ash storage facility on the West Virginia-Ohio border lays out part of the story. But the GAO's own summary does an admirable job of succinctly stating the bare facts:

(1) The exact number of surface impoundments at utility coal fired power plants is not known. However, the Environmental Protection Agency (EPA) is currently undertaking an effort to identify the number and location of all surface impoundments in the United States and, as of September 14, 2009, had identified over 580 surface impoundments nationwide.

(2) Problems that have been identified with the storage of coal ash include potential structural defects and other risks of collapse of the surface impoundment, such as at TVA Kingston Facility; health and environmental risks from [coal combustion residue] CCR storage due to potential leaching of contaminants into surface or groundwater from unlined or failed liners at surface impoundments, landfills, or sand and gravel pits; and potential risks from the discharge of wastewater containing CCR into surface waters from surface impoundments. EPA is currently analyzing the structural hazards and environmental risks associated with surface impoundments.

(3) EPA does not directly regulate CCR disposal in surface impoundments or landfills to prevent releases or a catastrophic spill, and states have a variety of regulatory controls on surface impoundments. EPA is developing proposed regulations but, as part of this effort, needs to address issues of federal and state roles for control and enforcement.

The full report, issued last Friday October 30th, can be read here. And an excellent overview of the findings from Facing South, here.
