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.
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.

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

GC4497
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 in area where topographic constraints
dictate culvert slopes will be 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.

and conditions of waters are suitable for all best uses.
12. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be
directed across the bridge and pre-treated through site -appropriate means to the maximum
extent practicable (e.g. grassed swales, pre -formed scour holes, vegetated buffers, etc.)
before entering the stream.

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: (2) 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.
21. Heavy equipment working in wetlands shall be placed on mats or other measures shall be
taken to minimize soil disturbance and compaction.

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.
22. In accordance with G.S 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.
