March 9, 2009 Coal Ash Information Request Letter

Highlights

On March 9, 2009, EPA issued Information Request Letters to electric utilities that have surface impoundments or similar units that contain coal combustion residuals.  The letters request information to assist EPA in evaluating the structural integrity of these management units. EPA, working closely with other federal agencies and the states, will review the information provided by the facilities to identify impoundments or similar units that need priority attention.  As part of this assessment effort, EPA will also be visiting many of these facilities to see first hand that the management units are structurally sound.  EPA will require appropriate remedial action at any facility that is found to pose a risk for potential failure.

The December 2008 release of coal ash from TVA's Kingston, Tennessee facility flooded more than 300 acres of land, damaging homes and property.  Coal ash from the release flowed into the Emory and Clinch rivers, filling large areas of the rivers and resulting in fish kills.

EPA is also developing regulations to address the management of coal combustion residuals. EPA anticipates having a proposed rule ready for public comment by the end of the year.

Assessment and analysis of surface impoundments or similar units resulting from this letter will be used in a report that will be made available to the public.
