This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the NCDWR and submit a new application. If the property is sold, the
new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as
described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
conditions listed in the attached certification(s) and any additional conditions listed below.
Condition(s) of Certification:
Project Specific Conditions
1. None
General Conditions
Unless otherwise approved in this certification, placement of culverts and other structures in open waters and
streams shall be placed below the elevation of the streambed by one foot for all culverts with a diameter
greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48
inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other
structures including temporary erosion control measures shall not be conducted in a manner that may result in
dis- equilibrium of wetlands or streambeds or banks, adjacent to or upstream and downstream of the above
structures. The applicant is required to provide evidence that the equilibrium is being maintained if requested
in writing by the NCDWR. If this condition is unable to be met due to bedrock or other limiting features
encountered during construction, please contact the NCDWR for guidance on how to proceed and to
determine whether or not a permit modification will be required.
2. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact
between curing concrete and stream water. Water that inadvertently contacts uncured concrete shall not be
discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
3. During the construction of the project, no staging of equipment of any kind is permitted in waters of the
U.S., or protected riparian buffers.
4. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams shall be restored to natural geomorphic conditions.
5. The use of rip -rap above the Normal High Water Mark shall be minimized. Any rip -rap placed for stream
stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life
passage.
6. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
7. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures
from the most current version of the NCDOT Construction and Maintenance Activities manual such as
sandbags, rock berms, cofferdams and other diversion structures shall be used to prevent excavation in
flowing water.
8. Heavy equipment shall be operated from the banks rather than in the stream channel in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream.
9. All mechanized equipment operated near surface waters must be regularly inspected and maintained to
prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
10. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
11. Discharging hydroseed mixtures and washing out hydroseeders and other, equipment in or adjacent to surface
waters is prohibited.

12. If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as
closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate.
Widening the stream channel should be avoided. Stream channel widening at the inlet or,outlet end of
structures typically decreases water velocity causing sediment deposition that requires increased maintenance
and disrupts aquatic life passage.
13. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes
aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed.
14. For the 10 linear feet of streams being impacted due to site dewatering activities, the site shall be graded to its
preconstruction contours and revegetated with appropriate native species.
15. The stream channel shall be excavated no deeper than the natural bed material of the stream, to the maximum
extent practicable. Efforts must be made to minimize impacts to the stream banks, as well as to vegetation
responsible for maintaining the stream bank stability. Any applicable riparian buffer impact for access to
stream channel shall be temporary and be revegetated with native riparian species.
16. The permittee and its authorized agents shall conduct its 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. If the NCDWR determines that such
standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State
or federal law is being violated, or that further conditions are necessary to assure compliance, the NCDWR
may reevaluate and modify this certification.
r
17. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification. i
18. A copy of this Water Quality Certification shall be maintained on the construction site at all times. In
addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained with
the Division Engineer and the on -site project manager. ' ,
19. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts
to areas within the fencing are prohibited unless otherwise authorized by this certification.
20. The issuance of this certification does not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances that may be imposed by other government agencies (i.e. local, state, and
federal) having jurisdiction, including but not limited to applicable buffer rules, stormwater management
rules, soil erosion and sedimentation control requirements, etc.
21. The Permittee shall report any violations of this certification to the Division of Water Resources within 24
hours of discovery.
22. The post - construction removal of any temporary bridge structures must return the project site to its
preconstruction contours and elevations. The impacted areas shall be revegetated with appropriate native
species.
23. Strict adherence to the most recent version of NCDOT's Best Management Practices For Bridge Demolition
and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality
Certification. P
24. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed across the bridge
and pre - treated through site - appropriate means (grassed swales, pre - formed scour holes, vegetated buffers,
etc.) before entering the stream. Please refer to the most current version of Stormwater Best Management
Practices.
25. Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft
construction methods. More specifically, jetting or other methods of pile driving are prohibited without prior
written approval from the NCDWR first.

i
i
26. No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter surface
waters. This water shall be captured, treated, and disposed of properly.
27. A turbidity curtain will be installed in the stream if driving or drilling activities occur within the stream
channel, on the stream bank, or within 5 feet of the top of bank. This condition can be waived with prior
approval from the NCDWR.
28. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify the
NCDWR when all work included in the 401 Certification has been completed.
29. Native riparian vegetation must be reestablished in the riparian areas within the construction limits of the
project by the end of the growing season following completion of construction.
30. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with
this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or
borrow sites, be located in wetlands or streams, compensatory mitigation will be required since that is a direct
impact from road construction activities.
31. Erosion and sediment control practices must be in full compliance with all specifications governing the
proper design, installation and operation and maintenance of such Best Management Practices in order to
protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and
maintained in accordance with the most recent version of the North Carolina Sediment and Erosion
Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures
must be such that they equal, or exceed, the requirements specified in the most recent version of the
North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all
construction sites, borrow sites, and waste pile (spoil) projects, including contractor -owned or leased
borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Surface Mining
Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance with
the requirements of the Sedimentation Pollution Control Act.
32. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved
by this Certification.
