SUBJECT: Dan River Bends Culvert Repair
APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Messenger:
You have our approval, in accordance with the attached conditions, to place a culvert in 30 linear feet and to stabilize
119 linear feet of perennial streams in order to conduct culvert repairs at the Dan River Bends in Stokes County, as
described in your application received by the Division of Water Quality on January 30, 2004. After reviewing your
application, we have determined that this fill is covered by General Water Quality Certification Number 3376 (GC 3376)
which can be viewed on our web site at http//h2o.enr.state.nc.us/ncwetlands. This Certification allows you to use
Nationwide Permit Number 3 when it is issued by the U.S. Army Corps of Engineers. In addition, you should get any other
federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion
Control, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying
404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us in writing and you may be required to send us a new application for a new certification. If the
property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for
complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the
conditions listed in the attached certification, as well as the additional condition listed below:
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.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the
impacts depicted in the Pre-construction Notice Application. All construction activities, including the design,
installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be
performed so that no violations of state water quality standards, statutes, or rules occur;

3. 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 date that the Division of Land Resources has released the project;
4. Culverts required for this project shall be installed in such a manner that original stream profiles are not altered. Existing
stream dimensions (including the cross section dimension, pattern, and longitudinal profile) are to be maintained above
and below the locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as
well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate
stream grade shall be re-established. If the pipes are installed in a perched manner, the pipes shall be removed and re-
installed correctly.
The culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream up-or down-
stream of the culvert(s). Existing stream dimensions (including the cross section dimension, pattern and longitudinal
profile) are to be maintained above and below locations of each culvert.
Native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable
instead of rip-rap or other bank hardening methods. If rip-rap is necessary, it shall not be placed in the stream bed,
unless specifically approved by the Division of Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately
accommodate high water or flood conditions;
5. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the
401 Certification has been completed.
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 150B 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 telephone Daryl Lamb in our Winston-Salem Regional Office at 336-771-4600 or Cyndi Karoly in the
Central Office in Raleigh 919-733-9721.

at the time of this application: This site is conservation land that is wooded and has a small
grassy open area. A narrow gravel drive leads to an existing canoe access. Site access is
Page 2 of 8
limited due to a locked entrance gate. Nearby land use is forest agriculture and a few
residences.
10. Describe the overall project in detail, including the type of equipment to be used:
This project proposes to repair an undersized culvert that is washing out on the driveway that
leads to a canoe access. A second culvert will be placed in the bottom of the channel with
the existing culvert placed at a higher elevation to carry flood flows. Culvert alignment will
direct flows toward the center of the channel instead of the downstream bank Damage to the
downstream bank will be repaired as part of this project. Repairs consist of laying back
slopes, revegetating the banks, toe protection and a deflector vane to keep stream power
centered in the stream channel. Proposed work will be done with a small backhoe working
from the top of the bank. Some gravel may be used as bedding for the new culvert. 11. Explain the purpose of the proposed work: Repairs are proposed to increase the storm flow
conveyance where an undersized culvert was installed, repair flood damage to the access
drive, and repair downstream bank scour.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are riot limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.stdte.nc.us/ncwetlands/strmgide.html.
