Closing and capping our ash ponds and other impoundments

Environmental coordinator standing in front of ash pond

As a result of the EPA's more stringent CCR Rule standards, we -- along with other utilities across the country -- launched aggressive projects to systematically close out all of our remaining ash ponds and surface impoundments.

Green River power plant
Approximately one-fourth of our impoundments are already closed and half are under contract for closure. 

Once processed, the dry materials will be stored on site at our power plants or beneficially reused offsite for materials, such as concrete, wallboard or fertilizer.

In some instances, we also are building new treatment and dry storage facilities. Currently, LG&E and KU’s CCR Rule Program and dry storage projects are on time and under budget. 

Cane Run before and after
Before and after: At our now-retired Cane Run power plant, we have closed and capped the ash pond, smaller process ponds and dry landfill.

  • Closure construction projects are underway, with one pond already closed. 
  • The engineering and construction for new CCR removal and treatment facilities are in progress. 
  • Additionally, we will be constructing a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash pond being closed. The new system is expected to be complete in 2019.

  • Closure construction projects are underway. 
  • We’re already operating new CCR removal and treatment facilities at the plant, and we’ll construct a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash pond being closed.  It’s expected to be complete in 2019.

  • We’re already operating new CCR removal and treatment facilities at the plant.
  • We also recently announced plans to reduce the size of our landfill by a third, eliminating an entire section that’s no longer needed. 
  • We’ll construct a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash pond being closed.  It also is expected to be complete in 2019.
