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 be valid, you must follow the conditions listed in the attached certification and any
additional conditions listed below.
Condition(s) of Certification:
1. 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.
2. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this
Certification.
3. 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.
4. This project has the potential to impact trout waters. No construction activities shall begin until the NCWRC makes a
determination regarding moratoria. Should the NCWRC determine that a moratorium is applicable, then the
requirements of any moratorium shall be a condition of this 401 Certification. If NCDOT does not wish to honor the
moratorium, then a written modification shall be requested.
5. The permittee shall use /Design Standards in Sensitive Watersheds/ [15A NCAC 4B.0124(a) -(e)] in areas draining to
(trout) waters. However, due to the size of the project, NC DOT shall not be required to meet 15A NCAC 4B
.0124(a) regarding the maximum amount of uncovered acres. Temporary cover (wheat, millet, or similar annual
grain) or permanent herbaceous cover shall be planted on all bare soil within 15 business days of ground disturbing
activities to provide erosion control.
Tall fescue shall not be used in the establishment of temporary or permanent groundcover within riparian areas. For
the establishment of permanent herbaceous cover, erosion control matting shall be used in conjunction with an
appropriate native seed mix on disturbed soils within the riparian area and on disturbed steep slopes with the
following exception. Erosion control matting is not necessary if the area is contained by perimeter erosion control
devices such as silt fence, temporary sediment ditches, basins, etc. Matting should be secured in place with staples,
stakes, or wherever possible, live stakes of native trees. Erosion control matting placed in riparian areas shall not
contain a nylon mesh grid, which can impinge and entrap small animals. For the establishment of temporary
groundcover within riparian areas, hydroseeding along with wood or cellulose based hydro mulch applied from a
fertilizer- and limestone -free tank is allowable at the appropriate rate in conjunction with the erosion control
measures. Discharging hydroseed mixtures and wood or cellulose mulch into surface waters in prohibited. Riparian
areas are defined as a distance 25 feet landward from top of stream bank.

6. 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.
7. 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.
8. 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.
9. 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 NCDWQ first.
10. 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.
11. All bridge construction shall be performed from the existing bridge, - temporary work bridges, temporary causeways,
or floating or sunken barges. If work conditions require barges, they shall be floated into position and then sunk. The
barges shall not be sunk and then dragged into position. Under no circumstances should barges be dragged along the
bottom of the surface water.
12. 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 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.
13. 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 stream bank stability. Any applicable riparian buffer impact for access to stream channel shall be
temporary and be revegetated with native riparian species.
14. 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.
15. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and
red maple) must be reestablished within the construction limits of the project by the end of the growing season
following completion of construction.
16. 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.
17. Rip -rap 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.
18. Heavy equipment shall be operated from the banks rather than in the stream channels in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream.
19. 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.
20. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted
for approval.
21. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is
prohibited.
22. 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.
23. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
24. 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.

25. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification.
26. 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.
27. 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.
28. 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 NCDWQ determines that such standards or laws are not being
met (including the failure to sustain a designated or achieved use) or that State of Federal law is being violated, or that
further conditions are necessary to assure compliance, NCDWQ may reevaluate and modify this certification.
29. The issuance of this certification does not exempt the Permittee form complying with any and all statutes, rules,
regulations or ordinances that may be imposed by othef 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.
30. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 -hours of
discovery.
31. 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 NCDWQ when all
work included in the §401 Certification has been completed.
Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or
civil penalties. This Certification shall become null and void unless the above conditions are made conditions of the -
Federal 404 and/or Coastal Area Management Act Permit. This Certification shall expire upon the expiration of the 404
or CAMA permit.
