As discussed with the North Carolina Department of Environmental Quality (NCDEQ) on
October 25, 2019, Duke Energy requests the concurrence for the installation of four additional
groundwater monitoring well at the Asheville Steam Electric Plant to support the assessment of
the Coal Pile. The Asheville coal plant decommissioning will begin in January 2020. To safely
perform the decommissioning activities, the groundwater monitoring wells CPA-2D/BR and
CPA-4D/BR are proposed for abandonment by the end of December 2019. Due to the
abandonment of CPA-2D/BR and CPA-4D/BR, Duke Energy is proposing to install two
additional monitoring well clusters (CPA-5D/BR and CPA-6D/BR) outside of the plant
decommissioning area and to provide additional monitoring points. The attached figure includes
the location of the well clusters proposed for abandonment and the proposed locations of the
new well clusters.
The new monitoring wells will be installed and sampled in accordance with the Asheville Coal
Pile Soil and Groundwater Assessment Technical Memorandum (SynTerra, June 2018)
(Memo), as approved by NCDEQ on July 31, 2018. Soil sampling will be conducted as part of
the well installation activities, as per the Memo.
If you have any questions or need any clarification regarding the information provided, feel free
to contact me at [e-mail] or at 980-373-6636 at your convenience.
