Dear Mr.Poupart:
In accordance with the requirements of Part III,Section D of NPDES wastewater permit NC0024406, Duke Energy
Carolinas, LLC (DEC) is hereby providing notice of closure for wastewater treatment components at our Belews
Creek Steam Station. As part of a Water Re-Route Project being undertaken to assure compliance with the Federal
Coal Ash Residual (CCR) rule for this facility, DEC will be closing the Constructed Wetlands. Wastewater
currently directed to the wetlands will be redirected to the ash basin and then to a new retention basin being
constructed in the footprint of the current wastewater treatment system wetlands. More details about that basin will
be provided in the upcoming submittal for NPDES renewal later this year. This work does not change the final
outfall discharge point of any flows at Belews Creek.
Details of the current status of the treatment units and the current plan for closure are:
• Constructed Wetlands. Constructed Wetlands receive flow from consolidated sump which includes
collection of wastewater from the sanitary waste system, stormwater collection pond (stormwater runoff
from gypsum and limestone stockpiles), limestone unloading facility sump, and leachate and contact
stormwater from FGD residual and Craig Road Landfills prior to discharge to Ash Basin, The plan for
closing the constructed wetlands is remove any residuals and dispose of off-site by a licensed contract
disposal firm, than the treatment unit will be replaced with retention basins which will discharge to Dan
River through permitted NPDES Outfall 003.
Please accept this letter as meeting the permit requirement to provide 90-days notice of closure for a wastewater
treatment system. If you have any questions regarding the closure of these treatment units, please contact Joyce
Dishmon at(336)394-5524,or via email at [e-mail].
