a copy of this Certification and is responsible for complying with all conditions. [15A NCAC
02H .0507(d)(2)].
If you are unable to comply with any of the conditions of the attached Water Quality General
Certification or with the additional conditions itemized below, you must notify the Mooresville
Regional Office within 24 hours (or the next business day if a weekend or holiday) from the time
the permittee becomes aware of the circumstances.
The permittee shall report to the Mooresville 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.
Additional conditions [15A NCAC 02H .0507(c)]:
1. Diversion ditches and other stormwater conveyances as related to the sediment and erosion
control measures shall be matted and/or stabilized to reduce sediment lost and turbidity. This
includes interior/exterior slopes of sediment basins. 15A NCAC 02H .05606 (b)(3) and (c) (3)
Justification: Failure to reduce erosion of runoff conveyances and to provide for maximum
reduction of erosion on areas not related to ongoing construction, shortens basin holding times,
increases turbidity of discharge and creates a greater potential of bypass discharge.
2. Bare/fill slopes in excess of 10 feet in height and within 30 feet of surface water shall be matted.
15A NCAC 02H .0506 (b)(1) and15A NCAC 02H .502 (c)
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
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. 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.
Justification: Turbidity can affect the growth rate of algae (micro -aquatic plants) and
other aquatic plants in streams and lakes due to a decrease a decrease in the amount of light for
photosynthesis. Turbidity can also increase water temperature because suspended particles
absorb more heat.
3. Stormwater discharge at this site shall be constructed in a manner such that the potential
receiving streams (of the discharge) will not be impacted due to sediment accumulations,
scouring or erosion of the stream banks. 15A NCAC 02B .0203

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.
4. WORK in wet: This authorization exempts the Permittee from meeting Condition II.9 in the
attached General Certification #4134 for the placement of in -stream structure material into
waters. 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 exemption does not authorize the use of
equipment within the stream channel for any other purpose such as a haul road, access,
streambank reshaping 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 stream banks such as toe protection and bank sloping. All reasonable steps
must be taken to limit the amount of disturbance in the channel and to therefore reduce
downstream turbidity during construction. This exemption does not relieve the Permittee of
meeting stream standards as indicated in 15A NCAC 02B. [15A NCAC 02H .0506(f)]
5. The permittee shall report to the DWR Mooresville 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).
Citation: 15A NCAC 02H.0506; 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 (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.
7. All activities shall be in compliance with any applicable State Regulated Riparian Buffer Rules in
Chapter 2B of Title 15A in the North Carolina Administrative Code.
Citation: 15A NCAC 02H.0506(b); 15A NCAC 02H.0507(c)
Justification: The referenced Riparian Buffer rules were adopted to address water quality
impairments and further protect existing uses.
8. When applicable, all construction activities shall be performed and maintained in full
compliance with G.S. Chapter 113A Article 4 (Sediment and Pollution Control Act of 1973).
Regardless of applicability of the Sediment and Pollution Control Act, all projects shall
incorporate appropriate Best Management Practices for the control of sediment and erosion so
that no violations of state water quality standards, statutes, or rules occur.

Design, installation, operation, and maintenance of all sediment and erosion control measures
shall be equal to or exceed the requirements specified in the most recent version of the North
Carolina Sediment and Erosion Control Manual, or for linear transportation projects, the North
Caroline Department of Transportation Sediment and Erosion Control Manual.
All devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil)
sites, including contractor -owned or leased borrow pits associated with the project. Sufficient
materials required for stabilization and/or repair of erosion control measures and stormwater
routing and treatment shall be on site at all times.
For borrow pit sites, the erosion and sediment control measures shall be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Surface Mining Manual. Reclamation measures and implementation shall comply with the
reclamation in accordance with the requirements of the Sedimentation Pollution Control Act
and the Mining Act of 1971.
9. Erosion control matting that incorporates plastic mesh and/or plastic twine shall not be used
along 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 impacts.
10. 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.
11. If concrete is used during construction, then all necessary measures shall be taken to prevent
direct contact between uncured or curing concrete and waters of the state. Water that
inadvertently contacts uncured concrete shall not be discharged to waters of the state.

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 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.
12. 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.
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, and the
