Improving land and water quality

We’re investing in our power plants to protect the environment and the communities we serve.

  • We are moving our power plant coal combustion residual materials to dry storage.
  • Our nearly $1 billion program is on time and under budget.
  • We are eliminating the use of ash ponds and other wet surface impoundments.
  • These projects meet new state water quality standards and the U.S. EPA’s Coal Combustion Residuals Rule.

Converting to dry management

We first embraced the idea of dry management for our coal combustion residuals, or CCRs, in 2008, well before the EPA’s CCR Rule. Already, our E.W. Brown, Mill Creek and Ghent power plants operate using dry handling and storage management, and our new dry management facility is nearly complete at our Trimble County power plant.

Protecting our community’s drinking water

Under our existing regulatory permits, we have monitored groundwater at some of our power plants since the 1980s to ensure drinking water for our community remains safe and is not impacted by our operations.

Herrington Lake Study

We’re committed to meeting or exceeding the requirements of our environmental permits at E.W. Brown Generating Station in order to ensure the water quality, aesthetics and recreational appeal of our beautiful Herrington Lake. Review the details of a recent lengthy and in-depth independent study.

Closing and capping our ash ponds and other impoundments

We are systematically closing out all of our remaining surface impoundments. Already, approximately one-half of these facilities are closed, and the other half are either under contract for closure or in the initial commercial phase of closure.

Impoundment Integrity Programs

We have stringent CCR management programs at our facilities. We monitor our CCR management facilities using weekly, monthly and annual inspection programs to ensure structural integrity. All of our management sites are inspected by state and federal agencies, third-party engineering firms, as well as our own engineers. As part of our inspection processes, we actively monitor our ash ponds, verify the structural integrity and conduct preventative maintenance.

Emergency Action Plans

We have emergency action plans for all LG&E and KU dams classified as “high” hazard, as defined by the CCR Rule.  It's important to note the hazard classification is not a measurement of the dam's structural integrity, but rather a classification of the potential for damage or other risks if the dam were to fail.  

Consistent with standard industry practice, these emergency action plans are closely managed and shared strictly with emergency management authorities responsible for responding at a company facility.

CCR Rule Compliance Data and Information

In our CCR Rule Compliance Data and Information section, you can access the company’s plans for compliance and information about each of LG&E and KU’s facilities regulated under the EPA's CCR Rule.
