Duke Energy (NYSE: DUK) has released inspection results of its coal ash basin pipes to the North Carolina Department of Environment and Natural Resources (NCDENR).
The third party inspections show that the infrastructure is safe, however, some areas of water infiltration were found. Duke said it is already developing engineering plans to repair or close certain pipes and to continue monitoring the others.
"These pipe inspections, and the steps we're taking to address any issues, demonstrate our ongoing commitment to safely managing coal ash at all of our basins," said Lynn Good, Duke Energy President and CEO.
Although NCDENR said that the officials did not find any public health or safety issues, the agency issued eight Notices of Deficiency. Duke will have to submit engineering assessments and repair plans for:
- Marshall Steam Station in Catawba County;
- Riverbend and Allen Steam Stations in Gaston County;
- Buck Steam Station in Rowan County; and
- Cliffside Steam Station in Rutherford and Cleveland counties.
NCDENR also issued three inspection letters requesting additional information on pipes at the Buck, Riverbend and Marshall Steam Stations.
