Dear Mr. McIntire:
The Division hereby withdraws the letter sent to you dated August, 28, 2014 that attempted to define
operatingconditions to allow the initiation of coal ash removal underyour existing NPDES permits. The
letter is being withdrawn due to concerns that were raised by the EPA in the attached September 16, 2014
letter.
Notwithstanding the delay in removing coal ash associated with a modification of your permits, NCDENR
agrees with EPA's suggestion that a modification process may be a better vehicle to initiate this work. If
you have any questions about this letter or the additional application requirements, please contact me at
(919) 807 -6309, or via a -mail at ieff.poupart()ncdenr :moo
Sincerely,
Jeff Poupart

Dear Mr. McIntire:
This letter is to clarify operating conditions for NPDES Permits issued to the above listed facilities. The
Permittne is authorized by the existing NPDES wastewater permits to decant all the wastewater in the ash
pond above the ash level provided the supernatant is directed through the same discharge point and
monitored in accordance with the NPDES permit requirements.
The Permittec is prohibited from removing wastewater by dredging the ash, excavating the trenches, or
any other mechanical movement of the ash. Duke Energy shall submit the chemical characterization of
the interstitial ash water from the ash basin and predicted volume of wastewater that will be generated by
mechanical dewatering.
If you have any questions about this letter, please contact me at (919) 807 -6309, or via e-mail at
