DWQ Project No. 011033
SR 1620 (Darnell-Woodie Road)
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 82
linear feet of Peak Creek, Laurel Fork and unnamed tributaries in order to improve SR 1620 (Darnell-
Woodie Road) in Ashe County. The project should be constructed in accordance with your application
dated 28 June 2001 (received 6 July 2001). 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 should 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 and submit a new application. - 1f 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 of total impacts to streams (now 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.
1. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the
brook and brown trout spawning season of October 15 through April 15, or as otherwise determined
by the North Carolina Wildlife Resources Commission, to protect the egg and fry stages of trout from
sedimentation during construction.
2. Storm water should be directed to buffer areas or retention basins and should not be routed directly
into streams.
3. Sedimentation and Erosion Control Guidelines for Sensitive Watersheds (15A NCAC 4B .0024) must
be implemented prior to any ground-disturbing activities to minimize impacts to downstream aquatic
resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil within
10 days of ground-disturbing activities to provide long term erosion control.
4. Culverts required for this project shall be installed in such a manner that the original stream profile is
not altered (i.e. the depth of the channel should not be reduced by a widening of the streambed) and
must insure passage for fish and other aquatic life. It should be noted that culverts at Sta. 20+40 and
Sta. 66+81 do not meet this criteria and must be amended during the construction project. Existing
stream dimensions are to be maintained above and below locations of culvert extensions.

Page 2 of 2_
5. All work shall be performed during low flow conditions.
6. All mechanized equipment operated near surface waters should be regularly inspected and maintained
to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic
materials.
7. The presence of equipment in the channels must be minimized. Under no circumstances should 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.
8. Mowing of existing vegetated buffers is strongly discouraged, so that they may be utilized for storm
water sheet flow.
9. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted
when practical. If necessary, rip-rap should be limited to the stream bank below the high water mark,
and vegetation should be used for stabilization above high water.
10. Rock silt screens at culvert outlets should be removed at project completion.
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 or Ms.
Jennifer Frye of the Winston-Salem Regional Office at 336.771.4600.

Subject: Nationwide Permit 414
SR 1620-A (Darnell-Woodie Road)
Ashe County, North Carolina
Dear Mrs. Manuele:

The NC Department of Transportation is scheduled to grade, drain, base, and pave primarily
along the existing roadway of SR 1620-A (Darnell-Woodie Road) in Ashe County. The paving
project will begin near the center of SR 1620 and will terminate at the intersection of SR 1620
and NC 18. This project will require the replacement of four (4) vet cross lines as shown below:
1) Replace existing 26'x 18" CMP at station 4+60 with a 50'x 36" CMP.
2) Replace existing 41'x24" CMP at station 64+70 with a 45'x 36" CMP.
3) Replace existing 41'x 24" CMP at station 75+30 with a 40'x 36" CMP.
4) Replace existing 55'x 48" CMP at station 83+50 with a 70'x 48" CMP.
Miscellaneous rip-rap impacts will total 40 linear feet or less (approximately 10 feet per crossing).
New stream impacts = 82 In. feet.
The wet crossing at station 4+60 carries an unnamed tributary of Peak Creek (Class: C, Trout +).
All of the remaining wet crossings carry different unnamed tributaries to Laurel Fork (Class: B,
Trout +). Since this is an existing roadway, the minor modifications proposed in this application
should not remove or degrade existing water quality uses. By utilizing the erosion control
measures outlined in the attachments to this application, downstream water quality standards will
be protected.

No Threatened or Endangered Species (or their critical habitat) will be impacted by this project.
Any widening of the existing roadway will be directed away from any adjacent creek whenever
possible with minimum fill placed in any buffer area. Pipe sizes used will be the minimum
necessary to create a safe roadway. The total project length is approximately 1.6 miles. Due to
the proposed work, we are requesting a 404 Nationwide Permit 914.
Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control
measures, pipe crossing drawings, buffer zone encroachment drawings, a marked county map, a
marked topography map and photographs.
By copy of this letter, it is requested that Mr. Ron Linville, Mountain Region Coordinator, with
the North Carolina Wildlife Resources Commission comment directly to you concerning the 404
Nationwide Permit application with a copy sent to me.
We will be requesting a variance from NCDENR, Land Quality Section for a temporary
encroachment into the trout water buffer zone of an unnamed tributary to Peak Creek (Class: C,
Trout +) from stations 2+00 - 4+50. In an attempt to minimize buffer impacts, the centerline of
the road has been shifted 3 feet away from the creek in this area. It is requested that Mr. Ron
Linville comment directly to me concerning this trout water buffer zone encroachment.
By copy of this letter, it is requested that Mr. Neil Trivette, Area Roadside Environmental
Engineer, comment on this project.
By copy of this letter, I am forwarding seven (7) copies of this application package to Cynthia
Van Der Wiele, NCDENR, Division of Water Quality, 401/Wetland Unit, for her review. A
$200.00 check is enclosed for the 401 certification processing fee. It is requested that any
comments related to the 401 certification be forwarded directly to the Corps with a copy sent to
me.
We would like to begin construction as soon as possible. If further information is required, please
let me know. Your early review and consideration will be greatly appreciated.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The existing roadway must be widened to achieve an acceptable section width, thus increasing
public safety. The existing pipes must also be upgraded for the same reason. By utilizing the
erosion control measures as shown in the attached drawings, adverse impacts to streams in the _
area will be minimized. Since this is an existing roadway, the stream impacts cannot be avoided.
However, the replacement pipe lengths will be the minimum needed to construct the widened
roadway. The centerline of the proposed has been shifted away from nearby streams to
minimize impacts to buffer zones.

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,
http://ii2o.enr.state.nc.us/newetiands/strm,Qide.litm1.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

Habitat Conservation Program ///'3 CC A ` -?
DATE: June 25, 2001
SUBJECT: North Carolina Department of Transportation (NCDOT), SR 1620, Darnell-
Woodie Road, Peak Creek and Unnamed Tributaries, Ashe 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.).
The proposed project consists of widening and paving SR 1620. Six culvert replacements will
affect 147 In. feet of Peak Creek and unnamed tributaries. In addition, NCDOT requests to
encroach on the trout water buffer zone from stations 38+50 - 40+50, 42+50 - 44+50 and from
84+50 - 87+00. Peak Creek supports a good Brook Trout population and, at the project location,
is on the edge of a High Quality Water Zone. A site visit revealed that the culverts at stations
20+40 and 66+81 currently have drop outlets (see appendix). This condition cannot persist
because it blocks aquatic life passage. We will not object to the project as proposed provided
that the following conditions are implemented:
1. Instream work and land disturbance within the 25-foot wide buffer zone are
prohibited during the brown and brook trout spawning season of October 15 through
April 15 to protect the egg and fiy stages of trout from off-site sedimentation during
construction.

2. 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.
3. The addition of pipes should ensure that all waters flow without freefalling or
damming on either end during low flow conditions. Pipes 36" or larger should be
buried approximately 1' into the streambed. Smaller pipes should be placed on grade
or preferably lower. The dimension, pattern, and profile of the stream above and
below the pipes should not be modified by widening the stream channel or reducing
the depth of the stream. Where disrupted, natural floodplain benching and aquatic
life passage should be restored.
4. Sediment and erosion control measures shall adhere to the design standards for
sensitive watersheds (15A NCAC 4B .0024).
5. Temporary or permanent herbaceous vegetation should be planted on all bare soil
within 10 days of ground disturbing activities to provide long-term erosion control.
NCDOT should utilize onsite native vegetation and materials for streambank
stabilization, rather than excessive riprap (or hard stabilization methods). Vegetation
provides bank stabilization, as well as shade for cooler water temperatures, and
riparian edge habitat. If riprap is used, it must be limited to the lower 1/3 of the
streambank.
6. If concrete will be used, work must be accomplished so that wet concrete does
not contact stream water. This will lessen the chance of altering the stream's
water chemistry and causing a fish kill.
7. Rock silt screens at culvert outlets should be removed at project completion.
8. Stormwater should be directed to buffer areas or retention basins and should not be
routed directly into streams.
9. Outside the moratorium period, we will allow temporary encroachment in the trout
buffer zone provided that areas within the buffers which have been cleared due to
grading requirements will be revegetated with riparian trees, shrubs, and
groundcovers, to match adjacent conditions.
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-
