EPA will collect information from electric utilities on the structural integrity of their coal ash impoundments and conduct on-site assessments. According to EPA [1], "The assessment and analysis of all such units located at electric utilities in the U.S. will be compiled in a report and made available to the public." The actions are in response to the 2008 coal ash spill [2] in Tennessee.
