Closing and capping our CCR impoundments

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.

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.

Today, open greenspaces -- with native grasses and pollinators -- are located within the footprint of our retired coal-fired power plants as well as several safely closed CCR impoundments.

We’re in the final stages of closing all of our wet CCR storage impoundments. As of April 2021, none of LG&E and KU's wet CCR storage impoundments receive CCR materials and about 75% are closed; the remaining facilities are either under contract for closure or in advanced commercial phases of closure. The remainder of our closure projects are expected to be complete by 2025.
