This approval requires you to follow the conditions listed in the certification below.
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 thatexceeds 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.

.0607(h)
Justification: In order to protect against impairment of water quality standards and best usage of
receiving and downstream waters, water quality based management practices must be
employed to protect against direct or indirect discharge of waste or other sources of water
pollution. Surface water quality standards require that conditions of waters be suitable for all
best uses provided for in state rule (including, at minimum: aquatic life propagation, survival,

and maintenance of biological integrity, wildlife, secondary contact recreation, agriculture) and
that activities must not cause water pollution that precludes any best use on a short-term or
long-term basis. In determining that the proposed activity will comply with state water quality
standards (in
antidegradation policy), the Division must evaluate if the activity has avoided and minimized
impacts to waters, would cause or contribute to a violation of standards, or would result in
secondary or cumulative impacts
2.Diversion Ditches and other storm water conveyances as related to the sediment and erosion
control measures shall be matted and/or stabilized to reduce sediment loss and turbidity.This
includes interior/exterior slopes of sediment basins.
Citation: 15A NCAC 02H .0506 (b)(3) and (c)(3)
Justification: Failure to reduce erosion of runoff conveyances and to provide for maximum
reduction of erosion on areas not related to ongoing construction, shortens basin holding times,
increases turbidity of discharge and creates a greater potential of bypass discharge.
3.Bare/fill slopes in excess of 10 feet in height and within 30 feet of surface waters shall be
matted.
Citation: 15A NCAC 02H .0506 (b)(1) and 15A NCAC 02H .502 (c)
Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. In determining that the proposed activity will
comply with state water quality standards(including designated uses, numeric criteria, narrative
avoided and minimized impacts to waters, would cause or contribute to a violation of standards
or would result in secondary or cumulative impacts
4.The permittee shall report to the DWR MooresvilleRegional Office any noncompliance with,
and/or any violation of, stream or wetland standards \[15A NCAC 02B .0200\], including but not
limited to sediment impacts to streams or wetlands. Information shall be provided orally within
24 hours (or the next business day if a weekend or holiday) from the time the permittee became
aware of the non-compliance circumstances.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
Justification: Timely reporting of non-compliance is important in identifying and minimizing
detrimental impacts to water quality and avoiding impacts due to water pollution that precludes
any best use on a short-term or long-term basis.
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).

12.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 flowand 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.
rt
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.
