Subject: Duke Energy Progress, Inc.
L. V. Sutton Energy Complex NPDES Permit NC0001422
Application Update in Response to NCDENR Notice of Modification
Dear Mr. Poupart:
Duke Energy Progress (DEP) hereby provides this update to the NPDES permit application,
originally submitted on July 28, 2014 in response to DENR's Notice of Modification dated March
14, 2014. We have also included the Major NPDES Modification fee of$1032.00. This
application update includes sample data for Outfall 001, as requested by your office, to
complete EPA Form 2C, Section V. The cooling pond at Sutton Plant has not discharged
through Outfall 001 since November 5, 2013. Therefore a representative sample was collected
inside the outfall structure of the cooling pond.
As you are aware, DEP is planning to remove coal combustion residuals (CCR) from the site in
the near future. We plan to discharge the wastewater generated by the dewatering and removal
of ash from the site through existing Outfall 004. We have characterized the wastewater to be
generated by sampling free water and entrapped, or interstitial, water in the ash basins. The
attached document provides an overview of our intended dewatering process and definitional
language regarding the wastewaters to be generated through this process. We expect that the
free water will meet current NPDES permit limits, but that additional treatment may be needed
as dewatering proceeds.

Sutton Dewatering Plan Synopsis
At the present time Duke Energy is expecting to discharge the wastewater generated from the removal
of ash (including dewatering of ash basins to allow excavation and dewatering of excavated ash prior to
being loaded onto trucks or rail cars)from the site through the current Outfall 004. It is anticipated that
as dewatering proceeds, Duke may bring in additional treatment may be needed to meet permit
discharge limits at Outfall 004.
The following definitions may be useful as you consider these activities:
Ash basin free water: Water in an ash basin located above the settled layer of ash. Ash basin
free water has undergone treatment in the ash basin, has the same general characteristics as
water discharged when the facility was active sluicing ash to the ash basing is largely devoid of
Total Suspended Solids and meets all applicable NPDES permit limits.
Ash basin interstitial water: Water in an ash basin that is located within the pore space of
accumulated wastewater sludge or slurry. Ash basin interstitial water must be removed by
some means such as trenching, well points, etc. and would likely require additional treatment
before being�released to the environment.
The process we envision for dewatering the ash basins to enable excavation and ash removal is as
follows:
The Sutton Plant has two Ash Basins on site, and they are referred to as the 1971 Basin and the 1984
Basin.The 1971 Basin contains a small storm water basin on the western side which we refer to herein
as the Outer 1971 Basin.The 1984 Basin contains an Interior Containment Area (ICA)that was
constructed in 2006. Based on data from July 2014, the 1971 Basin contains approximately 362
thousand gallons of free water and the 1984 Basin contains approximately 65 million gallons of free
water.
For the dewatering project,free water would be discharged only through existing Outfall 004 in the
North 1984 Basin.There is an existing splitter structure at Outfall 004 which allows for the discharge to
be routed directly to the cooling pond or bypassed to Outfall 001 (to the Cape Fear River). During
dewatering,the bypass to Outfall 001 will remain closed. Water will be discharged only to the Cooling
Pond from Outfall 004.
Free water dewatering will occur simultaneously in the 1984 and 1971 Basins. Water from the Outer
1971 Basin will be pumped,into the Inner 1971 Basin at an initial design flow rate of 575 gallons per
minute(gpm). Outer 1971 Basin free water will be pumped to the Inner 1971 Basin using a temporary
diesel pump with a screened floating intake. The water level in the basin on September 9, 2014 was
20.6 ft and the basin bottom elevation (as shown in historic drawings) is 11.5 ft.

Sutton Dewatering Plan Synopsis
There are currently two 12 in diameter ductile iron pipes that discharge to the southern tip of the 1971
Basin. These pipes convey stormwater collected from the West Retention Pond and the Fue'I Tank
Containment Area to the basin. To reduce the impact of stormwater from these pipes saturating the
dike walls in the narrow basin channel during the dewatering phase,the 12 in diameter pipes will be
modified to extend into a culvert pipe. The culvert will extend from approximately the-outlet location of
the 12 in pipes, along the narrow channel section of the Outer 1971 Basin and terminate into the main
body of the Outer 1971 Basin.
Free water from the Inner 1971 Basin'will be pumped directly to the North 1984 Basin at an initial-design
flow rate of 785 gpm. Free water from the Inner 1971 Basin will be pumped to the North 1984 Basin
using a temporary diesel pump with a screened floating intake. Water accumulated in the South 1984
Basin will be pumped to the Inner 1971 Basin or the area will be filled such that it will sheet flow to the
Inner 1971 Basin.
Similarly, water from the 2006 ICA will be pumped to the North 1984 Basin at an initial design flow rate
of 500 gpm. Free water in the 2006 ICA will be pumped to the North 1984 Basin using a temporary
diesel,pump with a'screened floating intake. The discharge hose will feed into the 2006 ICA discharge
tower.
The North 1984 Basin will be dewatered through,Outfall 004 via two temporary diesel pumps operated
at a combined.1,400 gpm , each with screened floating intakes. The pumps will operate in parallel and
discharge through a single hose to the North 1984 Basin discharge tower(Outfall 004).
All,pumps will be controlled,to stop at a user-defined level,set point which is set manually every 7 days.
The maximum free water drawdown rate will be one foot over seven days. If the free water level is
drawn down below the set elevation in 7 days or�less,the pumps will stop. At the end of each 7 day
period,the set point will be reset to 1 ft below the current water level. Following free water removal,
accumulated storm-water will be removed at a maximum rate of 2 feet over 1 day.
Historical discharge rates from.Outfall'004 were examined to ensure that dewatering discharge rates do
not exceed historical discharge rates. The average Outfall 004 discharge rate from January 2012,through
November 2013 is 4.05 million gallons per day(MGD),or 2,810 gpm . The design pumping rate from the
duplex pumps in the North 1984 Basin to the,Outfall 004 discharge tower is 1,400 gpm. The maximum
discharge rate of these pumps is 2,525 gpm at 2,200 rpm and 10 ft of suction lift.
The North 1984 Basin pumps will be controlled with a real-time total suspended solids(TSS) meter.A
real-time pH meter will control a carbon dioxide injection system to maintain pH between 6.0 and 9.0
standard units (SU). The sensors for the real-time TSS and pH meters will be inserted directly into the
discharge piping.
In addition to the real-time monitoring, handheld TSS and pH meters will be used daily for field
measurement of samples taken from sample port located on the discharge piping manifold of the North
1984 Basin dewatering pumps. The handheld TSS meter will undergo laboratory validation and site-

specific field verification. Daily pH monitoring will be conducted with a portable pH meter. Discharge
flow rates will be monitored daily using an inline flow meter, a handheld flow meter,or a v-notch
discharge weir. Staff gauges will be used to monitor daily water levels within the North 1984 Basin.
Normal monitoring required by the N'PDES permit will continue uninterrupted during the dewatering
process.
As the dewatering process transitions from the free water phase to the interstitial,water phase it is
anticipated that a filtration system will be used to maintain compliance with permit limits. Please
include a provision in the modified permit to allow the use of a coagulant or flocculent from the state's
approved list to facilitate the filtration process if,needed.
We have included a process flow diagram and basin map as attachments,for your reference.
