Dear Mr. Pettyjohn:
You have our approval, in accordance with the attached conditions and those listed below, to incur the following impacts
in order to pave, widen and improve traffic safety on SR 1116 (Boone Gap Rd) in Wilkes County.
• 128 linear feet of new piping impacts to three unnamed tributaries to Big Warrier Creek (96 feet of new pipe impacts
and 30 feet of rip-rap impacts); and
• Temporary dewatering impacts of approximately 0.015 acres at station 79+11.
The project shall be constructed in accordance with your application dated February 6, 2006. After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification Nos. 3404 and 3366,
corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 14 and 33 respectively. 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 federal permit. This condition supercedes condition No. 19 in the General Certification 3404, and
condition No. 12 in General Certification 3366.
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 Division of Water Quality (Division) and submit a new application. If the
property is sold, the new owner must be given a copy of this approval letter and certifications, 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 2H .0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the conditions
listed in the attached certification and any additional conditions 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.

SR 1116 (Boone Gap Road)
Wilkes County, North Carolina
Project Number: 11C.097083 (DWQ Permit Fee: $200)
Dear Mr. Thomas:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1116,
Boone Gap Road in Wilkes County. Total project length is approximately 1.60 miles. The
roadway width will increase from 16' to 18' and be paved. Impervious surface area will increase
by 0.39 acres. This project will require the replacement of three (3) wet pipes as shown below:

Station Number Existing Structure
Size Proposed Pipe
Size Riprap Impacts
feet Total Impacts at
this Station ft.
31+77* 28'x48" 100'x48" 10 82
37+13 40'x36" 60'x48" 10 30
79+I1 36'x60" 40'x60" 10 14
Total Stream Impacts = 126 feet
* The proposed pipe skew and subsequent pipe length at station 31+77 are necessary in order to
keep the curve at this location from getting sharper and therefore becoming a public safety issue.
The replacement of the existing wet pipe at station 79+11 will require temporary dewatering. An
impervious sandbag dike will be constructed approximately 20 feet upstream of the existing
structure to create a small pool. Clean water will temporarily be pumped around the construction
area and will be discharged into a buffer area downstream. Any dirty water located inside the
construction area will be pumped into a silt bag. The dewatered area at station 79+11 will total
approximately 0.015 acres. Once the new structure is in place, the impervious dike will be
removed and preconstruction streambed elevations will be restored.

Construction of this project will require impacts to waters of the United States in the Yadkin
River Basin. All wet pipes carry different unnamed tributaries of Big Warrior Creek (Class: C).
This project was reviewed for the presence of threatened and endangered species on February 2,
2006. This project will have no effect on any federally listed endangered plant or animal species.
The State Historic Preservation Office has reviewed this project and did not request any survey
work.
The proposed project should not remove or degrade existing water quality uses. Pipe sizes used
will be the minimum necessary to create a safe roadway. All pipes with a slope greater than 6%
will remain perched and an energy dissipator pad will be installed at the pipe outlet. By utilizing
the erosion control measures outlined in the attachments to this application, downstream water
quality standards will be protected. All appropriate BMPs will be used during construction.
Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control
measures, 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.
By copy of this letter, I am forwarding seven (7) copies of this application package to John
Hennessy, NCDENR, Division of Water Quality, 401/Wetlands Unit, for his review. It is
requested that any continents related to the 401 certification be forwarded directly to me with a
copy sent to the US Army Corps of Engineers.
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 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.
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
safely construct the paved roadway. All appropriate BMPs will be used during construction
Vili. Mitigation
DWQ - In accordance with 15A NCAC 21-1 .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

MEMORANDUM
TO: John Thomas, Permit Coordinator
Raleigh Office. U.S. Ann Corps of Engineers
?.". ?"
FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: February 7, 2006
SUBJECT: SRI 116, Boone Gap Road, Unnamed Tributary Big Warrior Creek, Wilkes County
North Carolina Department of Transportation (NCDOT) is requesting a letter of concurrence from the
North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404 permit from the U.S. Amly
Corps of Engineers. The NCWRC has reviewed information provided by the applicant, and field
biologists on our staff are familiar with habitat values of the project area. These comments are provided
in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 ct. seq.) and the Fish and
Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The project will grade, base, drain and pave SRI 116. Three existing pipes will be replaced with longer
and upgraded piping. Temporary dewatering will be necessary. Total impacts will be 126 linear feet of
stream. No trout arc known for these waters.
Based on the information provided by the applicant and our knowledge on the range of trout in the project
area, we do not believe this project will cause significant effects to waters supporting trout. Therefore, we
do not object to the project as proposed providing that pipes arc installed in a manner to promote aquatic
life passage to the extent practicable, including creation of base channels in rock dissipater pads. Where
possible, culverts 48 inches diameter or larger should be buried a foot into the strcambcd. Culverts less
than 48 inches diameter should be buried to a depth equal to or greater than 20% their size to allow for
aquatic life passage. These measurements must be based on natural thalweg depths.
Thank you for the opportunity to review and comment on this project. If you have any questions
regarding these comments, please contact me at 336/769-9453.
