Re: Dan River Landfill Cell 1 Supplemental Chimney Drains Permit No.: 7906-INDUS
Dan River Steam Station
Rockingham County
Eden, North Carolina 27288
Dear Mr. Frost,
On June 19, 2017, two significant rainfall events resulted in the breach of CCR material out of
Cell 1 of the Dan River Landfill. CCR material from the breach was contained within the
footprint of future Cells 2 and 3 and properly disposed of in a timely manner. To prevent recurrence, the landfill operations team recommended installing two supplemental chimney
drains in Cell 1.
Attached is the chimney drain detail and approximate locations in Cell 1. Once the chimney
drains are installed, record drawings with the actual locations will be submitted to the Solid Waste Section for documentation. This letter serves as a request for concurrence from the
NCDEQ Division of Waste Management Solid Waste Section to install the supplemental
chimney drains in Cell 1 of the Dan River Landfill.
Duke Energy is committed to excellent environmental stewardship and cooperation with the Division regarding the operation, maintenance, safety, and integrity of all of its facilities. We
look forward to continuing to work with you regarding environmental concerns.
If you have any questions or comments related to the submittal of this document please do not
hesitate to contact Melonie Martin at 336-445-0610 or melonie.martin@duke-energy.com.
Respectfully submitted,
Melonie Martin
