John Seymour Leads Course on Structural Integrity Considerations Under the CCR Rule

John Seymour will serve as an instructor at the American Coal Ash Association (ACAA) & University of Kentucky Center for Applied Energy Research, sponsored by the Electric Power Research Institute (EPRI), "Workshop on Current Issues in Ponded CCPs" meeting in Tampa, Florida on February 3, 2016.

His topic is "Structural Integrity Considerations under the CCR Rule." John will consider the significant requirements to evaluate the "structural integrity" (slope stability and hydraulic spillway capacity) of existing CCR surface impoundments under the U.S. EPA Coal Combustion Residuals (CCR) Rule. Structural integrity includes both the minimum factors of safety for slope stability and the capacity of spillways to pass the required storm flows. The important elements of the work required to meet the structural integrity criteria, including the time to reach conclusions, will be presented to allow for comprehension of the magnitude of potential outcomes. The potential outcomes include: i) acceptable conditions, and ii) modifications required. If modifications are required, a timeline of events will be provided that will demonstrate the importance to act immediately. Approaches to meet the requirements of the structural integrity criteria will be presented. The Rule was published in April 2015 and was effective on October 19, 2015.
