9. An NPDES Construction Stormwater Permit (NCG010000) is required for construction
projects that disturb one (1) or more acres of land. The NCG010000 Permit allows
stormwater to be discharged during land disturbing construction activities as stipulated in
the conditions of the permit. If the project is covered by this permit, full compliance with
permit conditions including the erosion & sedimentation control plan, inspections and
maintenance, self-monitoring, record keeping and reporting requirements is required. [15A
NCAC 02H .0506(b)(5) and (c)(5)]
10. All work in or adjacent to streams shall be conducted so that the flowing stream does not
come in contact with the disturbed area. Approved best management practices from the
most current version of the NC Sediment and Erosion Control Manual, or the NC DDT
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams,
and other diversion structures shall be used to minimize excavation in flowing water. [15A
NCAC 02H .0506(b)(3) and (c)(3)]
11. Culverts shall be designed and installed in such a manner that the original stream profiles are
not altered and allow for aquatic life movement during low flows. The dimension, pattern,
and profile of the stream above and below a pipe or culvert shall not be modified by widening
the stream channel or by reducing the depth of the stream in connection with the
construction activity. The width, height, and gradient of a proposed culvert shall be such as to
pass the average historical low flow and spring flow without adversely altering flow velocity.
[15A NCAC 02H .0506(b)(2) and (c)(2)].
Where multiple pipes or barrels are proposed, they shall be designed to mimic the existing
stream cross section as closely as possible including pipes or barrels at flood plain elevation
and/or sills where appropriate. Widening the stream channel shall be avoided.
If bedrock is discovered during construction, then DWR shall be notified by phone or email
within 24 hours of discovery.
The establishment of native woody vegetation and other soft stream bank stabilization
techniques shall be used where practicable instead of rip -rap or other bank hardening
methods.
12. Application of fertilizer to establish planted/seeded vegetation within disturbed riparian
areas and/or wetlands shall be conducted at agronomic rates and shall comply with all
other Federal, State and Local regulations. Fertilizer application shall be accomplished in a
manner that minimizes the risk of contact between the fertilizer and surface waters. [15A
NCAC 0213.0200 and 15A NCAC 026 .0231]

13. If concrete is used during construction, then all necessary measures shall be taken to prevent
direct contact between uncured or curing concrete and waters of the state. Water that
inadvertently contacts uncured concrete shall not be discharged to waters of the state. [15A
NCAC 0213 .0200]
14. No temporary impacts are allowed beyond those included in this Certification. All temporary
fill and culverts shall be removed and the impacted area shall be returned to natural
conditions within 60 calendar days after the temporary impact is no longer necessary. The
impacted areas shall be restored to original grade, including each stream's original cross
sectional dimensions, planform pattern, and longitudinal bed profile. All temporarily
impacted sites shall be restored and stabilized with native vegetation. [15A NCAC 02H
.0506(b)(2) and (c)(2)]
15. All proposed and approved temporary pipes/culverts/rip-rap pads etc. in streams shall be
installed as outlined in the most recent edition of the North Carolina Sediment and Erosion
Control Planning and Design Manual or the North Carolina Surface Mining Manual or the
North Carolina Department of Transportation Best Management Practices for Construction
and Maintenance Activities so as not to restrict stream flow or cause dis-equilibrium during
use of this Certification. [15A NCAC 02H .0506(b)(2) and (c)(2)]
16. Any riprap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All riprap shall be buried and/or "keyed in" such that the original
stream elevation and streambank contours are restored and maintained. Placement of riprap
or other approved materials shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area. [15A NCAC 02H .0506(b)(2)]
17. Any rip -rap used for stream or shoreline stabilization shall be of a size and density to prevent
movement by wave, current action, or stream flows and shall consist of clean rock or masonry
material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed
except in specific areas required for velocity control and to ensure structural integrity of bank
stabilization measures. [15A NCAC 02H .0506(b)(2)]
18. All mechanized equipment operated near surface waters shall be inspected and maintained
regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids,
or other toxic materials. Construction shall be staged in order to minimize the exposure of
equipment to surface waters to the maximum extent practicable. Fueling, lubrication and
general equipment maintenance shall not take place within 50 feet of a waterbody or
wetlands to prevent contamination by fuels and oils. [15A NCAC 02H .0506(b)(3) and (c)(3)
and 15A NCAC 0213 .0211 (12)]

19. Heavy equipment working in wetlands shall be placed on mats or other measures shall be
taken to minimize soil disturbance. [15A NCAC 02H .0506(b)(3) and (c)(3)]
20. In accordance with 143-215.85(b), the applicant shall report any petroleum spill of 25
gallons or more; any spill regardless of amount that causes a sheen on surface waters; any
petroleum spill regardless of amount occurring within 100 feet of surface waters; and any
petroleum spill less than 25 gallons that cannot be cleaned up within 24 hours.
21. Mr. Steve Cahoon and Duke Energy shall conduct construction activities in a manner
consistent with State water quality standards (including any requirements resulting from
compliance with section 303(d) of the Clean Water Act) and any other appropriate
requirements of State and Federal law. [15A NCAC 0213.0200] If the Division determines that
such standards or laws are not being met (including the failure to sustain a designated or
achieved use) or that State or federal law is being violated, or that further conditions are
necessary to assure compliance, the Division may reevaluate and modify this Certification.
Before modifying the Certification, the Division shall notify Mr. Steve Cahoon and Duke
Energy and the U.S. Army Corps of Engineers, provide public notice in accordance with 15A
NCAC 02H .0503 and provide opportunity for public hearing in accordance with 15A NCAC
02H .0504. Any new or revised conditions shall be provided to Mr. Steve Cahoon and Duke
Energy in writing, shall be provided to the U.S. Army Corps of Engineers for reference in any
Permit issued pursuant to Section 404 of the Clean Water Act, and shall also become
conditions of the 404 Permit for the project.
22. Upon completion of all permitted impacts included within the approval and any subsequent
modifications, the applicant shall be required to return a certificate of completion (available
on the DWR website https:lledocs.deg.nc.gov/Forms/Certificate-of-Completion). [15A NCAC
02H .0502(f)]
23. If the property or project is sold or transferred, the new Permittee shall be given a copy of
this Certification (and written authorization if applicable) and is responsible for complying
with all conditions. [15A NCAC 02H.0501 and .0502]
24. This Certification does not relieve the applicant of the responsibility to obtain all other
required Federal, State, or Local approvals before proceeding with the project, including
those required by, but not limited to Sediment and Erosion Control, Non -Discharge, Water
Supply Watershed, and Trout Buffer regulations.
