2. At all three pipe locations, the streams are extremely sinuous. Care must be taken by NCDOT to align the pipes
as best as possible to ensure stability of the channel above and below the pipes. Some channel relocation or
modification may be necessary to prevent future stream is =stability, NCDOT,staff shall address pipe alignment at
each site upon pipe installation and if necessary, the NCD(~T Division Environmental Officer, NCDOT
Environmental Specialist, or NCDWQ staff will be consulted to review the alignment prior to final road grading
and paving. ~ -
3. At various locations along this new road extension, the stream channel is parallel,'and immediately adjacent to,
the road fill slope .and construction area. Extra care will be necessary in desigiii7g, installing, and maintaining
proper erosion control measures to ensua-e no impacts to stream at these locations. Should if become necessary to
provide addlional stream stabilization al these parallel locations, a permit modific~~tion will be required.
4. Erosion arid~'sediment control practices must be in full coripliance 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 implen ~ntation must comply with the reclamation in accordance with the
requirements of the Sedimentation PoII;:`tion Control Act.
5. No waste, spoil, solids, or fill of any kind si5a11 occur in wetlands,_ waters, or riparian areas beyond.the footprint of
the impacts depicted in the Preconstructiort,~Totice Application. All construction activities, including- the design,
installation, operation, and maintenance c-' sediment and erosion control Best Management Practices, shall be
performed so that no violations of state water quality standards, statutes, or rules occur.
6. 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 within six months of the completion of the project.
7. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing
season following completion of construction.
8. Stormwater should be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site
for the purpose of pre-treating. stormwater runoff, and must not be routed directly into streams. Mowing of
existing vegetated buffers is strongly discouraged, so that they maybe utilized for stormwater sheet flow.
9. Where practicable, 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. This may require increasing the size of the culvert to
meet flow conveyance requirements. If any of the existing pipes are perched, they shall be removed and replaced,
and re-installed correctly, unless demonstrated that this is topographically unfeasible. All waters must flow
through without freefalling or damming on either end of the culverts during low flow conditions, to maintain
aquatic life and/or fish passage.
10. 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. "

11. Disturbed floodplains and streams should be restored to natural geomorphic conditions.
12. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical.
If rip-rap is necessary, it must be limited to the stream bank below the high water mark, and vegetation must be
used for stabilization above high water. Any rip-rap used must not interfere with aquatic life passage during low
flow conditions.
13. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water. This will
lessen the chance of altering the stream's water chemistry and causing a fish kill.
14. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize
sedimentation and reduce the likelihood of introducing other pollutants into the stream.
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. The presence of equipment in the channels must be minimized. Under no.circumstances must rock, sand or other
materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate
vicinity of the culverts.
17. Temporary dewatering sites must be restored to preexisting conditions unless more natural geomorphic conditions
can be provided.
18. All work shall be performed during low flow conditions.
19. Upon completion of the project, the NCDOT shall complete 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.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to
Chapter 15.OB of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please contact Sue Homewood at 336-771-4964 or at [e-mail].
Sincerely,
~~
