Subject: Revised Interim Monitoring Plans for 14 Duke Energy Facilities
2nd Quarter 2018
Dear Mr. Draovitch:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
LINDA CULPEPPER
Interim Director
The North Carolina Department of Environmental Quality (DEQ) is providing the attached revised
Interim Monitoring Plans (IMPs) for the respective coal ash facilities. Per our agreement, DEQ
will be providing Duke Energy with updated IMPs quarterly until the individual facility Corrective
Action Plans are approved, and Duke Energy will include and begin sampling any newly installed
groundwater assessment wells as part of the facility IMP which DEQ will formally include in the
subsequent IMPs.
The attached IMPs only contain references to groundwater monitoring locations. Sampling at
surface water locations that were identified as part of the May 1, 2017 communication from DEQ
to Duke Energy regarding revised IMPs at the facilities is expected to continue pending further
notice. For clarification, we have also provided the minimum expected groundwater sampling
analyte list.
The attached revised facility IMPs shall be conducted on a quarterly basis commencing the fourth
quarter of calendar year 2017 pursuant to 15A NCAC 02L .0110, until Corrective Action Plans
are approved for the individual facilities or as directed otherwise by DEQ. The quarterly sampling
events will be conducted in conjunction with planned compliance monitoring sampling events for
three quarters during the calendar year, supplemented with an additional sampling event conducted
at each facility in order to provide four rounds of monitoring data to evaluate seasonal fluctuations
during a year-long timeframe. If sampling an individual groundwater location is problematic,
please contact the appropriate Regional Office.
Since Duke Energy is in the process of submitting Comprehensive Site Assessments, the
requirement for an annual monitoring report submitted by April 30th for each respective coal
facility as set forth in the May 1, 2017 letter will be extended to a date in 2018 that will be later
defined.

In order to optimize the groundwater monitoring at each facility, DEQ will be removing the
groundwater monitoring condition from the NPDES permits as they are reissued. Duke Energy
shall continue to monitor the compliance wells separately under the individual NPDES permits
until the NPDES permits are reissued with no groundwater monitoring condition. At that time,
the compliance wells shall continue to be monitored per the attached revised IMPS under the
authority of 15A NCAC 02L .0110.
DEQ is open to consider further optimization of the IMPs following a qualitative and quantitative
review of site-specific data. A thorough analysis of spatial and temporal trends related to
contaminant distribution that include determination of background conditions and identification of
areas impacted by coal. ash residuals must be provided as a decision framework to support
improvements to long-term monitoring programs.
If you have any questions, please feel free to contact the appropriate Regional Office or Steve
Lanter (Central Office) at [phone].
Sincerely,
S. ykierman, P.G.
