Subject: Revised Interim Monitoring Plans for 14 Duke Energy Facilities
Yd 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. DEQ may elect
to require establishment of surface water monitoring program in the future related to the ongoing
IMPs or corrective action performance monitoring. The requirement for an annual monitoring
report for each respective coal facility as set forth in the May 1, 2017 letter submitted will be due
April 30, 2019.
The attached revised facility IMPS shall be conducted on a quarterly basis 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.
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].
