10. The Permittee shall take all reasonable measures to construct in -stream structures while keeping
heavy equipment out of the stream channel. Only equipment that is being used to install structures
may enter the stream channel. This approval does not authorize the use of equipment within the
stream channel for any other purpose such as haul road, access, streambank shaping, etc.
Equipment shall access the stream at the closest point possible to reduce impacts to the stream bed.
The majority of stream flow shall be diverted around work areas along the streambanks such as toe
protection and bank sloping. Approved best management practices from the most current version of
the NC Sediment and Erosion Control Manual, or the NC Department of Transportation Construction
and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams, and other diversion
structures shall be used to minimize excavation in flowing water. All reasonable steps must be taken
to limit the amount of disturbance in the channel and to therefore reduce downstream turbidity
during construction. This approval does not relieve the Permittee of meeting stream standards as
indicated in 15A NCAC 02B.

receiving water shall not exceed 50 Nephelometric Turbidity Units (NTU) in streams not designated
as trout waters and 10 NTU in streams, lakes, or reservoirs designated as trout waters, for lakes and
reservoirs not designated as trout waters, the turbidity shall not exceed 25 NTU; if turbidity exceeds
these levels due to natural background conditions, the existing turbidity level shall not be increased.
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. 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.

deleterious substances, or colored or other wastes: only such amounts as shall not render the waters
injurious to public health, secondary recreation, or to aquatic life and wildlife, or adversely affect the
palatability offish, aesthetic quality, or impair the waters for any designated uses. As cited in
Wetland Standards: (c)(1) Liquids, fill or other solids, or dissolved gases shall not be present in
amounts that may cause adverse impacts on existing wetland uses, and (3) Materials producing
color or odor shall not be present in amounts that may cause adverse impacts on existing wetland
uses.
15. All proposed and approved 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.

Justification: A project that affects waters shall not be permitted unless the existing uses, 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 after project completion.
17. Any rip -rap 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 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)
Justification: Surface water quality standards require that conditions of waters be suitable for all best
uses provided for in state rule, and that activities must not cause water pollution that precludes any
best use on a short-term or long-term basis. 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.
18. 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.

Justification: Surface water quality standards require that conditions of waters be suitable for all best
uses provided for in state rule, and that activities must not cause water pollution that precludes any
best use on a short-term or long-term basis. 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.
19. 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 be performed in a manner to prevent, to the maximum extent practicable,
contamination of surface waters by fuels and oils.

Justification: Person(s) owning or having control over oil or other substances upon notice of
discharge must immediately notify the Department, or any of its agents or employees, of the nature,
location, and time of the discharge and of the measures which are being taken or are proposed to be
taken to contain and remove the discharge. This action is required in order to contain or divert the
substances to prevent entry into the surface waters. 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.
22. The permittee and their authorized agents shall conduct all activities in a manner consistent with
State water quality standards (including any requirements resulting from compliance with §303(d)
of the Clean Water Act), and any other appropriate requirements of State and Federal Law.
