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.
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.
