Subject: Revised Interim Monitoring Plans for 14 Duke Energy Facilities
4'' Quarter 2018
Dear Mr. Draovitch:
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 or as directed otherwise by DEQ, 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 currently participating in reviews to optimize the groundwater monitoring programs at the
Duke Energy coal ash facilities. This review process will result in revisions to the current
groundwater monitoring programs until corrective action is implemented at the respective facilities
and may streamline the effort related to quarterly IMP changes.
If you have any questions, please feel free to contact the appropriate Regional Office or Steve
Lanter (Central Office), at [phone].
Sincerely,
`Y
