shall not exceed 25 NTU; if turbidity exceeds these levels due to natural background conditions,
the existing turbidity level shall not be increased.
10. In-stream structures installed to mimic natural channel geomorphology such as cross-vanes,
sills, step-pool structures, etc. shall be designed and installed in such a manner that allow for
continued aquatic life movement.
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. Ensuring that in-stream structures
are installed properly will ensure that surface water quality standards are met and conditions of
waters are suitable for all best uses.
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

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. Ensuring that structures are installed
properly in waters will ensure that surface water quality standards are met and conditions of
waters are suitable for all best uses.
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.
