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 wet surface impoundments.

Closure Construction
Closure construction projects are well underway at our Green River power plant. The photo on the left was taken in the winter of 2017, while the photo on the right was taken in the fall of 2018.

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

We are operating our E.W. Brown, Ghent, Mill Creek and Trimble County power plant’s new CCR treatment and dry processing facilities, and we constructed new state-of-the-art process water treatment facilities at each station to treat waters that come in contact with CCR materials. 

Cane Run before and after
Before and after: At our now-retired Cane Run power plant, we have closed and capped the ash pond and dry landfill. In these photos, you can see what these projects looked like during and after construction.

Mill Creek

  • Closure construction plans are underway, with four of five CCR impoundments already closed, with the last impoundment planned for closure in 2021. 
  • Additionally, in 2019 we constructed a new process-water treatment system to treat waters that come in contact with CCR materials prior to the impoundments being closed. 

Ghent

  • Closure construction plans are underway, with one impoundment already closed. Three of the remaining four impoundments at the plant have started closure activities. 
  • We’re already operating new CCR treatment facilities at the plant, and in 2020, we began operating  a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash ponds being closed.   

Trimble County

  • In 2019, we completed construction of new CCR treatment facilities and a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash pond being closed. 

E.W. Brown

  • Closure construction plans have begun at E.W. Brown.
  • We are already operating new CCR treatment facilities at the plant.
  • We reduced the size of our landfill by a third, eliminating an entire section that’s no longer needed.
  • We constructed a new process-water treatment system to treat waters that come in contact with CCR materials prior to the ash pond being closed, and this system is expected to be fully operating later this year.

Cane Run, Green River, Pineville and Tyrone

  • We closed and capped the ash pond, smaller process ponds and dry landfill at our retired coal-fired Cane Run power plant, and in 2019, we also closed impoundments located at our retired Green River, Pineville and Tyrone power plants.
