Engineers, consultants, utility representatives and other scientists in the coal ash industry gathered in Tampa, Florida on February 3 and 4th to attend the workshop on “Current Issues in Ponded CCP’s." The University of Kentucky Center for Applied Energy Research (UK CAER) and the American Coal Ash Association (ACAA) co-hosted the 1 1/2 day event that was held in conjunction with ACAA’s annual meeting. Additionally, the Electric Power Research Institute (EPRI) was a workshop sponsor and co-organizer.

Expert speakers from the CAER and industry gave technical presentations to a crowd of 192 attendees. Those presentations included:

  • Nature of Ponds, Sediments, Structure of Ponds - by Dr. Robert Jewell, UK CAER
  • The Recovery and Beneficiation of Ponded Fly Ash - by Dr. Tom Robl, UK CAER
  • Slope Stability Considerations under the CCR Rule - by Mr. John Seymour - Geosyntec
  • Progress Report on Seismic Shear Wall Stabilization of Perimeter Dikes and Loose Sand Foundation by Deep Mixing Method (DMM) - Experiences from Ongoing Construction at TVA's Colbert Ash Pond 4 - by Bill Walton, GEI
  • The New Regulatory Regime - The New Rules Summary - by Mr. John Ward, John Ward, Inc
  • Framework for Evaluating the Relative Impacts of Surface Impoundment Closure Options - by Ms. Ari Lewis, Gradient
  • Groundwater Monitoring and Statistical Analysis Under the CCR Rule - by Mr. Bruce Hensel, EPRI
  • Corrective Action at CCP Ponds - by Ken Ladwig, EPRI
  • In-Situ Stabilization/Solidification of Coal Ash Residuals - by Adam Chwalibog, Arcadis U.S., Inc.
  • North Carolina's Unprecedented Scope, Schedule, and Scrutiny: Insights for the Industry - by Dr. John Daniels, UNCC
  • Pond Closures: How to Avoid "Breaking the Bank" - by Mr. Mark Rokoff, AECOM




The UK CAER’s Environmental and Coal Technologies Group investigates all aspects of coal combustion by-product utilization (flyash). As such, it generates information for the transfer of new ideas to benefit the innovative utilization, handling, storage and disposal of CCBs.

The American Coal Ash Association, established in 1968, is a nonprofit trade association devoted to recycling the materials created when we burn coal to generate electricity. Our members comprise the world's foremost experts on coal ash (fly ash and bottom ash), and boiler slag, flue gas desulfurization gypsum (FGD or "synthetic" gypsum), and other flue gas materials captured by emissions controls.
