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
criteria and the state's 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.
4. Because the stormwater management plan approved by Harnett County is being used to meet
stormwater requirements on this project, you are required to submit a digital copy of the
approved stormwater management plan (SMP) including plan details on scaled plan sheets with
proof of Harnett County approval. The approved SMP shall be submitted to Chonticha McDaniel of
the DWR 401 and Buffer Permitting Branch (Chonticha.mcdaniel@ncdenr.gov) before any impacts
authorized in this certification occur. After it is approved, the SMP may not be modified without
prior written authorization from Harnett County. If modified, a digital copy of the approval letter
and the modified SMP shall also be submitted to the DWR 401 & Buffer Permitting Branch (at the
email address above) prior to the commencement of the modifications. [15A NCAC 02H .0506(b)
and 0507(c)]
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 (including
designated uses, numeric criteria, narrative criteria and the state's 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.
5. The permittee shall report to the DWR Fayetteville Regional 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.
6. 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).

streambanks or within wetlands.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
Justification: A project that affects waters shall not be permitted unless the existing uses (including
aquatic life propagation and biological integrity), and the water quality to protect such uses, are
protected. Protections are necessary to ensure any remaining surface waters or wetlands, and any
surface waters or wetlands downstream, continue to support existing uses during and after project
completion. 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

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.

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 criteria and the
state's 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.
e. Permanent maintained access corridors in wetlands and across stream channels shall be
restricted to the minimum width practicable and shall not exceed 30 feet wide except at
manhole locations.

g.
f. For all utility lines constructed within wetlands, an anti -seep collar shall be placed at the
downstream (utility line gradient) wetland boundary and every 150 feet up the gradient until
the utility exits the wetland. Anti -seep collars may be constructed with class B concrete,
compacted clay, PVC pipe, or metal collars. Wetland crossings that are directionally drilled, and
perpendicular wetland crossings that are open cut and less than 150 feet long do not require
anti -seep collars. The compacted clay shall have a specific infiltration of 1 X 10- 5 cm/sec or
less. A section and plan view diagram is attached for the anti -seep collars.
The following specifications shall apply to class B concrete:
i. Minimum cement content, sacks per cubic yard with rounded coarse aggregate 5.0
ii. Minimum cement content, sacks per cubic yard with angular coarse aggregate 5.5
iii. Maximum water -cement ratio gallons per sack 6.8
iv. Slump range 2" to 4"
v. Minimum strength - 28-day psi 2,500

The permittee shall have a specific plan for restoring wetland contours to pre -construction
conditions. Any excess material will be removed to a high ground disposal area.
The mixing of topsoil and subsoils within the wetlands along utility corridors shall be
minimized to the greatest extent practical. During excavation, the soils shall be placed on
fabric to minimize impacts whenever possible. Topsoil excavated from utility trenches will
be piled separately from subsoils and will be backfilled into the trench only after the
subsoils have been placed and compacted.
