Coal Combustion Residuals Impoundment Reports

As part of the U.S. Environmental Protection Agency’s ongoing national effort to assess the management of coal combustion residuals (CCR), EPA is releasing the final contractor reports assessing the structural integrity of impoundments and similar management units containing coal combustion residuals, commonly referred to as “coal ash,” at facilities. Most of the impoundments have a “high” or “significant” hazard potential rating.
