CONDITIONS OF CERTIFICATION [15A NCAC 02H .0507(c)]:
1. Stormwater Management: The applicant may provide documentation that the project will not impair
water quality to the receiving stream(s) from stormwater runoff or provide an approved stormwater
management plan. Any high density project and/or project that exceeds density thresholds must
provide a stormwater management plan for the entire project, for review and approval including all
forms and pertinent items that complies with the high density development requirements. Low
density development shall meet all condition for stormwater management required by the state and
be reviewed if required. The plan may be approved by the Division, State Stormwater Program or a
local delegated authority. The plan shall consider the impact of the volume and velocity of discharge
and runoff to the receiving stream and adjacent riparian areas to prevent scouring and erosions of the
features.

5. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the footprint of
the approved impacts (including temporary impacts). Citation: 15A NCAC 02H .0506; 15A NCAC 02H
.0507(c)
6. Culverts (temporary/permanent) 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. If the
width of the culvert is wider than the stream channel, the culvert shall include multiple boxes/pipes,
baffles, benches and/or sills to maintain the natural width of the stream channel. If multiple
culverts/pipes/barrels are used, low flows shall be accommodated in one culvert/pipe and
additional culverts/pipes shall be installed such that they receive only flows above bankfull.
Placement of culverts and other structures in streams shall be below the elevation of the streambed
by one foot for all culverts with a diameter greater than 48 inches, and 20% of the culvert diameter
for culverts having a diameter less than or equal to 48 inches, to allow low flow passage of water
and aquatic life. If the culvert outlet is submerged within a pool or scour hole and designed to
provide for aquatic passage, then culvert burial into the streambed is not required.
For structures less than 72" in diameter/width, and topographic constraints indicate culvert slopes
of greater than 2.5% culvert burial is not required, provided that all alternative options for flattening
the slope have been investigated and aquatic life movement/connectivity has been provided when
possible (e.g. rock ladders, cross -vanes, sills, baffles etc.). Notification, including supporting
documentation to include a location map of the culvert, culvert profile drawings, and slope
calculations, shall be provided to DWR 30 calendar days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required, provided that there is
sufficient documentation of the presence of bedrock. Notification, including supporting
documentation such as a location map of the culvert, geotechnical reports, photographs, etc. shall
be provided to DWR a minimum of 30 calendar days prior to the installation of the culvert. If
bedrock is discovered during construction, then DWR shall be notified by phone or email within 24
hours of discovery.
Installation of culverts in wetlands shall ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions. When roadways, causeways, or other fill
projects are constructed across FEMA-designated floodways or wetlands, openings such as culverts
or bridges shall be provided to maintain the natural hydrology of the system as well as prevent
constriction of the floodway that may result in destabilization of streams or wetlands.
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. Citation: 15A
NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
7. 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. Citation: 15A 02H .0506(b); 15A NCAC

9. All proposed and approved temporary (including fill/culverts/riprap) impacts shall be removed and
the impacted area(s) 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 and
allow to naturalize. Citation: 15ANCACO2H.0506(b);15ANCACO2H.0507(c)
10. Any rip -rap required for proper culvert placement, stream stabilization, or restoration areas shall be
restricted to the area approved within the application.. Soft/natural stabilization shall be utilized to
the maximum extent practicable. All rip -rap shall be placed such that the original streambed
elevation and streambank contours are restored and maintained and shall consist of clean rock or
masonry material free of debris or toxic pollutants. Placement of rip -rap or other approved
materials shall not result in de -stabilization of the stream bed or banks upstream or downstream of
the area or be installed in a manner that precludes aquatic life passage. Citation: 15A NCAC
02H .0506(b); 15A NCAC 02H .0507(c)
11. Any rip -rap used for shoreline or streambank 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. Citation: 15A NCAC 02H .0506(b), 15A NCAC 02H .0507(c), 15A NCAC 02B .0201
