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.
18. 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.

Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. Activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. As cited in Stream Standards: (12) Oils,
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 of fish, 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.

21. 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.

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.
22. 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.

not be present in amounts that may cause adverse impacts on existing wetland uses.
23. Heavy equipment working in wetlands shall be placed on mats or other measures shall be taken to
minimize soil disturbance and compaction.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c); 15A NCAC 028 .0231
Justification: Wetland standards require maintenance or enhancement of existing uses of wetlands
such that hydrologic conditions necessary to support natural biological and physical characteristics are
protected; populations of wetland flora and fauna are maintained to protect biological integrity of the
wetland; and materials or substances are not present in amounts that may cause adverse impact on
existing wetland uses.
24. In accordance with 143-215.85(b), the permittee shall report any petroleum spill of 25 gallons or
more; any spill regardless of amount that causes a sheen on surface waters; any petroleum spill
regardless of amount occurring within 100 feet of surface waters; and any petroleum spill less than 25
gallons that cannot be cleaned up within 24 hours.

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.
25. 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.
