Subject: NPDES Stormwater Permit Application
Additional Information Request
Rogers Energy Complex (Cliffside Steam Station)
Cleveland and Rutherford Counties
Dear Mr. Sideris:
The Division of Energy, Mineral and Land Resources' Stormwater Permitting Program (SPP)
received an application for an NPDES stormwater permit for this facility on August 4, 2014. We need
additional information from Duke Energy Progress, Inc. ("Duke") to continue processing that
application and developing a draft permit.
Please resubmit EPA Form 1 General, indicating in Section IX whether of not the facility is
located on Indian lands.
Please explain what is meant by "In developed areas" submitted as "Supplemental
Information under "GENERAL SITE INFORMATION" in the third paragraph of the first page.
Please explain what "DOT Regulations are followed" submitted as "Supplemental
Information in Section "YARD DRAINAGE BASIN," subsection "Significant Materials/Controls - Oil" in
the first paragraph. DOT regulates hazardous materials in transportation. I'm not aware of any
Federal or State DOT regulations for fuel oil storage tanks, a dispenser, and dikes.
Please clarify the third paragraph in Section "YARD DRAINAGE BASIN," subsection
"Significant Materials/Controls - Oil" that discusses "USED OIL" and "WASTE OIL." The first sentence
refers to a 4,000 gallon used oil storage tank. The fourth paragraph refers to a waste oil tank. It is
unclear as to whether or not you are describing one tank or two separate tanks - one for used oil and
another for waste oil.
In accordance with item V of the EPA Form 2F application, please confirm that Duke has
observed all stormwater outfall conveyances on the site and that Duke has reason to conclude that
the observed additional flow is groundwater only. If any other outfalls were not observed, or they
included non-stormwater flows, please amend the EPA Form 2F. If any other discharges have
occurred during dry periods please indicate how those discharges are currently permitted.

Our understanding was that Duke would follow the same format as the Riverbend
application in subsequent application submittals, including sample results from all stormwater
discharge outfalls. Please provide sampling results for all stormwater discharge outfalls at this site,
or provide a schedule for sampling the remaining outfalls and following up with the results.
Pleased clarify the Site Plan.
1. The plan shows a SW003, but does not show a drainage area 3, nor does the supplement
information discuss either SW003 or Drainage Area 3.
2. The supplement information discusses "Outfall SW015 (Drainage Area 15), but the plan does
not indicate a location for SW015.
3. The supplement information discusses "Outfall SW016 (Drainage Area 16), but the plan does
not indicate a location for SW016.
4. Neither the site plan nor the supplement information make mention of an SW013 or
Drainage Area 13. Are we to understand there is not a SW013 or Drainage Area 13?
Please provide analytical sampling results for stormwater discharges (SW001, SW002,
SW004, SW005, SW009, SW011, SW012, SW015, and SW016).
Please provide details (dates, location on site, drainage area impacted, etc.) about the
presence or any past storage and/or releases of polychlorinated biphenyl compounds (PCBs) on site.
If there were any known releases, please discuss actions taken to remediate any areas affected.
Include information about what drainage areas might have been impacted by PCBs.
Thank you for providing more recent copies of the annual certification all outfalls had been
inspected for non-stormwater discharges. All of the certifications indicated that no discharges were
occurring during periods of no precipitation. For future reference on other stormwater applications
for this facility or other Duke facilities, if any outfalls were not observed, or they included non-
stormwater flows, please amend your EPA Form 2F to report that. Also, if any discharges have
occurred during dry periods, be sure to indicate in the application how those discharges are or will
be permitted.
We are asking that you provide this information by September 22, 2014. Otherwise we will
return the application as incomplete. Also, please provide an electronic copy of all application
materials, including this additional information, along with your submittal. If you have any questions
about this matter, please contact me at (919) 807-6378 or bradley.bennett(@ncdenr.govor or Mike
Randall at (919) 807-6374 or mike.randall(@ncdenr.gov.
