certifies that this activity will not violate the applicable portions of Sections 301, 302, 303, 306, 307 of
PL 92-500 and PL 95-217 if conducted in accordance with the application and conditions hereinafter set
forth.
This approval is only valid for the purpose and design that you submitted in your application, as described
in the Public Notice. Should your project change, you are required to notify the DWQ 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 any additional wetland impacts,
or stream impacts, for this project (now or in the future) exceed one acre or 1501inear feet, respectively,
additional compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and (7).
For this approval to remain valid, you are required to comply with all the conditions listed below. In
addition, you should obtain all other federal, state or local permits before proceeding with your project
including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge and
Water Supply watershed regulations. This Certification shall expire three years from the date of the cover

1. Prior to incurring impacts anywhere on the project, a revised natural channel design shall be
submitted to, and approved by, the NC Division of Water Quality. The revised plan shall
include proposed construction plans that describe how DOT plans to conduct phased
construction of the new stream channel and control downstream transport of sediment in
Michael Branch. Please describe how the phased construction of the stream relocation, the
stream meanders, and the bank stabilization and vegetation will be conducted in a dry work
area as detailed in Condition 8. of the General Conditions. The revised plan shall be submitted
to the NC Division of Water Quality within thirty (30) days of the issuance of this Certification.
A copy of the revised stream design and construction plan shall also be submitted to the NC
Wildlife Resources Commission.
2. The dimension, pattern and profile of the stream above and below the crossing should not be
modified by widening the stream channel or reducing the depth of the stream. Disturbed
floodplains and streams should be restored to natural geomorphic conditions. All stream
relocation and restoration activities shall comply wit the final natural channel design plans
approved by the NC Division of Water Quality.
General Conditions of Certification:
3. Construction will be conducted in such a manner as to prevent a significant increase in turbidity
outside the area of construction orconstruction-related discharge. 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
assure compliance with the appropriate turbidity water quality standard.
a. The erosion and sediment control measures for the project must equal or exceed the
proper design, installation, operation and maintenance outlined in the most recent version of
the North Carolina Sediment and Erosion Control Planning and Design Manual. These
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.
b. For borrow pit sites, the erosion and sediment control measures must equal or exceed the
proper design, installation, operation and maintenance outlined in the most recent version of
the North Carolina Surface Mining Manual. The reclamation measures and implementation
must comply with the reclamation in accordance with the requirements of the Sedimentation
Pollution Control Act.
4. All sediment and erosion control measures shall not be placed in wetlands or waters to the
maximum extent practicable. If placement of sediment and erosion control devices in wetlands
and waters is unavoidable, they shall be removed and the natural grade restored after the
Division of Land Resources has released the project.
5. If an environmental document is required, this Certification is not valid until a FONSI
or ROD is issued by the State Clearinghouse. All water quality-related conditions of the
FONSI or ROD shall become conditions of this Certification.

6. No live or fresh concrete shall come into contact with waters of the state until the concrete has
hardened.
7. There shall be no excavation from or waste disposal into jurisdictional wetlands or waters
associated with this permit without appropriate modification of this permit. Should waste or
borrow sites be located in wetlands or stream, compensatory mitigation will be required since it
is a direct impact from road construction activities.
8. All channel relocations will be constructed in a dry work area, and stabilized before stream
flows are diverted. Channel relocations will be completed and stabilized prior to diverting
water into the new channel. Whenever possible, channel relocations shall be allowed to
stabilize for an entire growing season. Vegetation used for bank stabilization shall be limited to
native woody species, and should include establishment of a 30 foot wide wooded and an
adjacent 20 foot wide vegetated buffer on both sides of the relocated channel to the maximum
extent practical. A transitional phase incorporating coir fiber and seedling establishment is
allowable. Also, rip-rap may be allowed if it is necessary to maintain the physical integrity of
the stream, but the applicant must provide written justification and any calculations used to
determine the extent of rip-rap coverage requested. ,
9. Upon completion of the project, the NCDOT shall cotiiplete and return the enclosed
"Certification of Completion Form" to notify DWQ when all work included in the 401
Certification has been completed. The responsible party shall complete the attached form and
return it to the 401/Wetlands Unit of the Division of Water Quality upon completion of the
project.
10. Placement of culverts and other structures in waters, streams, and wetlands must be placed
below the elevation of the streambed to allow low flow passage of water and aquatic life unless
it can be shown to DWQ that providing passage would be impractical. 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 down stream of the above structures. The applicant is required to
provide evidence that the equilibrium shall be maintained if requested in writing by DWQ.
11. 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.
12. All temporary fills in wetlands and surface waters shall be removed upon completion of the
project. In addition, the post-construction removal of any temporary bridge structures or fill
will need to return the project site to its preconstruction contours and elevations. The
revegetation of the impacted areas with appropriate native species will be required.
13. Riparian vegetation must be reestablished within the construction limits of the project by the
end of the growing season following completion of construction.
14. Any riprap used must not interfere with thalweg performance and aquatic life passage during
low flow conditions.

15. 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.
16. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or
adjacent to surface waters is prohibited.
17. Two copies of the final construction drawings shall be furnished to NCDWQ prior to the pre-
construction meeting. Written verification shall be provided that the final construction
drawings comply with the attached permit drawings contained in the application dated May 11,
2004.
18. The outside buffer, wetland or water boundary located within the construction corridor
approved by this authorization shall be clearly marked by orange fabric fencing prior to any
land disturbing activities.
19. NCDOT, 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 law and Federal law. If
DWQ 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 lbw is being violated, or that further
conditions are necessary to assure compliance, DWQ may reevaluate and modify this
certification to include conditions appropriate to assure compliance with such standards and
requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the certification,
DWQ shall notify NCDOT and the US Army Corps of Engineers, provide public notice in
accordance with 15A NCAC 2H.0503 and provide opportunity for public hearing in accordance
with 15A NCAC 2H.0504. Any new or revised conditions shall be provided to NCDOT in
writing, shall be provided to the United States Army Corps of Engineers for reference in any
permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions
of the 404 Permit for the project.
20. A copy of this Water Quality Certification shall be posted 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.
21. Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater
than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch in diameter or
larger should be buried at least 12 inches below the stream bottom to allow natural stream
bottom material to become established in the culvert following installation and to provide
aquatic life passage during periods of low flow. These measurements must be based on natural
thalweg depths.
