APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. Heath Slaughter, Division Environmental Officer
NCDOT Division 11
P.O. Box 250
North Wilkesboro, NC 28659
Dear Mr. Slaughter:
You have our approval, in accordance with the attached conditions and those listed below, to impact
90 linear feet of Cain Mill Branch in order to replace Bridge No. 138 on SR 1160 in Yancey County.
The project must be constructed in accordance with your application dated February 18, 2002
(received February 20, 2002). After reviewing your application, we have decided that this fill is
covered by General Water Quality Certification No. 3289, corresponding to the U.S. Army Corps of
Engineers Nationwide Permit Number 14. In addition, you must acquire any other federal, state or
local permits before you proceed with your project including (but not limited to): Sediment and
Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval will expire
with the accompanying 404 permit unless otherwise specified in the Water Quality Certification.
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 DWQ in writing 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 if total impacts to streams (now or in the
future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC
211.0506 (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.
1. Bridge demolition must follow NCDOT's BMP's for Bridge Demolition and Removal (final,
9/20/99).
2. Storm water must be directed to buffer areas or retention basins and must not be routed directly
into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they may be
utilized for storm water sheet flow.
3. Sediment and erosion control measures shall adhere to NCDOT's, Best Management Practices
for the Protection of Surface Waters (March 1997).
4. NCDOT is encouraged to use existing on-site vegetation and materials for streambank
stabilization and to minimize the use of rip rap.
5. The culverts shall be designed and constructed so that they can be installed one foot below
streambed grade to enable waters to transport sediment and ensure passage of all aquatic life. -
The dimension, pattern, and profile of the stream and floodplain above and below the structure
shall not be modified by widening the stream channel or reducing the depth of the stream.
Disturbed floodplain benching should be restored to natural geomorphic conditions in front of the
concrete headwall and upstream and downstream of the second. stormwater flow pipe.

919-733-1786 (phone), 919-733-6893 (fax), http://h2o.enr.state.nc.us/ncwetlands/
6. All work shall be performed during low flow conditions.
7. Live (wet) concrete shall not come into contact with the stream; this causes fish kills.
8. Disturbance of the stream channel must be limited to only what is necessary to perform the
culvert installation. 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.
Upon completion of the project, the NCDOT shall complete and return the enclosed
"Certificate of Completion" form to notify NCDWQ 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 NC 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 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 Ms. Cynthia Van Der Wiele at 919.733.5715

(DWQ Permit Fee $200)
The NC Department of Transportation is scheduled to replace Bridge #138 on SR 1160 in Yadkin
County. The existing structure is a 30-foot long single span bridge with timber abutments. The
proposed new crossing consists of (2) 50'x 95" x 67" CSPAs with a concrete headwall. Pipe #2
will carry stormwater only.
Miscellaneous rip-rap impacts will total 40 linear feet or less. New stream impacts = 90 In. feet.
The replacement of the existing bridge with the proposed CSPAs will require temporary
dewatering. An impervious sandbag dike will be constructed approximately 20 feet upstream of
the existing culvert to create a small pool. Clean water will temporarily be pumped around the
construction area and will be discharged into a buffer area -located approximately 90 feet
downstream of the sandbag dike. Any dirty water located inside the construction area will be
pumped into a silt bag. The dewatered area will total approximately 630 square feet or 0.015
acres. Once the new structure is in place, the impervious dike will be removed and
preconstruction streambed elevations will be restored.
R
Construction of this project will necessitate impacts to waters of the United States in the Yadkin, w
River Basin. The culvert in question will carry Cain Mill Branch (Class Q. The Division I 1
Environmental Officer reviewed this project for the presence of threatened and endangered
?A
species on February 14, 2002. The subject project has been determined to have no effect on' any'
federally listed endangered plant or animal species. Historic compliance work will be scheduled
and concurrence with the State Historic Preservation Office will be obtained if required.

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 not 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

Habitat Conservation Program
DATE: February 26, 2002
SUBJECT: NCDOT bridge replacement of No. 138 on SR 1160 over Cain Mill Branch,
Yadkin County
The North Carolina Department of Transportation (NCDOT) is requesting a concurrence
letter from the North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404 permit
from the U.S. Army Corps of Engineers. Biologists on staff with the NCWRC have reviewed
the proposed improvements and are familiar with habitat values of the project area. These
comments are provided in accordance with the provisions of the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d) and the Clean Water Act of 1977 (33 U.S.C.
466 et seq.).
NCDOT proposes to replace Bridge No. 138 with (2) 50'x 95" x 67" CSPAs with a
concrete headwall. The culvert instillation plus bank stabilization will impact 90 linear feet of
Cain Mill Branch. This project has the potential to impact Cain Mill Branch through off-site
sedimentation during construction and blockage of aquatic life movements through improper
placement of the culvert. While our preference would be to replace the bridge with another
spanning structure, we will not object to the project as proposed provided that the following
conditions are implemented:
Disturbance of the stream channel must be limited to only what is necessary
to install the culvert. Heavy equipment should be operated from the bank
rather than in the stream channel in order to minimize sedimentation and
reduce the likelihood of introducing other pollutants into the stream.
2. The pipes should be constructed so that all water flows through only
one cell during low flow conditions. At least one pipe should be buried
one foot into the substrate. The second pipe should be placed on the floodplain
bench and function only when the stream channel is at flood stage. Stream
Bridge No. 138, SR 1160 2 February 26, 2002
conditions above and below the "active" pipe should be maintained at pre-
construction channel widths and depths to provide sediment transport and
aquatic'life movement. Where disrupted, natural floodplain benching should be
restored.
3. Stringent erosion control measures should be installed where soil is disturbed
and maintained until project completion.
4. Temporary or permanent herbaceous vegetation should be planted on all bare soil
within 15 days of ground disturbing activities to provide long-term erosion control.
We encourage NCDOT to utilize onsite vegetation and materials for streambank
stabilization, to minimize the use of riprap (or hard stabilization methods) and to
maximize the use of native vegetation for stabilization and shade.
5. Work must be accomplished so that wet concrete does not contact stream
water.
6. Only clean, tear-free sandbags should be used as temporary fill for dewatering, and
should be removed without excessive disturbance of the natural stream bottom when
construction is completed. The streambed should be returned to pre-construction
conditions upon removal of the sandbags.
Thank you for the opportunity to review and comment on this project during the early
planning stages. If you have any questions regarding these comments, please contact me at (336)
527-1549.
