Subject: Nationwide Permit #14
SR 2148 (Oak Hollow Road)
Wilkes County, North Carolina
Project Number: 110.097127 (DWQ Permit Fee: $240)
Dear Mr. Matthews:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 2148, Oak
Hollow Road in Wilkes County. Total project length is approximately 0.82 miles. The roadway
will be ~ti7dened from 16 feet to 18 feet with impervious surface area increasing by 0.2 acres. This
project will require the replacement of one wet pipe as shown below:

Impacts (feet) Total Impacts at
this Station (ft.)
19+0~ 30'x 24" 60'x 24" 10 40

Total Stream Im acts = 40 feet
The replacement of the above noted wet pipe will require temporary dewatering. An impervious
sandbag dike will be constructed upstream of the existing culvert to create a small pool. Clean
water will temporarily be pumped around the construction area and will be discharged
downstream. Any dirty water located inside of the construction area will be pumped into a silt
bag if necessary. Total dewatered area will be approximately 0.002 acres. Once the new pipe is
in place, the impervious dike will be removed and preconstruction streambed elevations will be
restored.

The wet pipe in question carries an unnamed tributary to Elkin Creek (Class: WS-II, HQW). This
project was reviewed for the presence of threatened and endangered species on January 16, 2008.
This project will 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.
The project impacts are minor in nature and should not remove or degrade existing water quality
uses. Pipe sizes used will be the minimum necessary to create a safe roadway. 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 five (5) copies of this application package to John
Hennessy, NCDENR, Division of Water Quality, 401/Wetlands Unit, for his review. It is
requested that any comments 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.
Sincerely,
~~

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 existingroadway 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

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 ~k~atershed.
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.state. nc. us/ncwetlands/strm~ide. html.
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.

unhewn quarry stone. The stone shalt be sound, tough, dense,
resistant to the action of air and water, and suitable in all other
respects for the purpose intended. Where broken concrete from
demolished structures or pavement is available, it may be used
in place of stone provided that such use meets with the approval
of the Engineer. However, the use of broken concrete which
contains reinforcing steel will not be permitted.
The stone or broken concrete shalt be graded to meet the
following requirements:
1. For Class 1 Rip Rap -The stone shall vary in weight
from 5 to 200 pounds. At least 30 percent of the total
weight of the rip rap shall be in individual pieces
weighing a minimum of 60 pounds each. Not more
than 10 percent of the total weight of the rip rap may
be in individual pieces weighing less than 15 pounds
each.
2. For Class 2 Rip Rap - Stone shall vary in weight from
25 to 250 pounds. At least 60 percent of the total
weight of the rip rap shall be in individual pieces
weighing a minimum of 100 pounds each. Not more
than 5 percent of the total weight of the rip rap may
be in individual pieces weighing less than 50 pounds
each.

HIGH QUALITY WATERS
1. Uncovered areas are limited at any given time to a maximum total area of
20 acres.
2. Erosion and sedimentation control measures shall be designed to provide
protection from the 25-year storm.
3. Large Type-A basins shall be designed and constructed with a settling
efficiency of at least 70% for the 40 micron soil particle size transported
by runoff from the 2-year storn~.
4. Newly constricted channels shall be constructed with side slopes no
steeper than 2:1, unless slopes are to be stabilized by methods other than
vegetation
5. Aground cover sufficient to restrain erosion must be provided for any
disturbed area.

NOTES FOR EROSION CONTROL PLAN
• Each Section Under Constriction Shall be Seeded and Mulched ~b'ithin 30 Days After Grubbing
Begins (Per STF,P # 7 of the Lmsion Control Design). Sec Phasing Sheet on Nest Page for Section
Layouts.
• 9' X 3' ~ 2' Temporary Rock Sediment Dam, Type-B Used at ALL Locations as Shown. ALL are
Greater Than or Equal to the Required Storage Given in STEP # 7 of the Designer Spreadsheet.
• If a Temporary Silt Ditch is Used in Place of Temporary Silt Fence, Then .ALL Rock Silt Checks Type
B & A Need to be Placed in TSD Per STEP # 3 & 5 (Respectively) of the Erosion Control Designer
Spreadsheet.
• Outlet Devices Along Silt Fence May Need to be Relocated Only to be Placed in the Low Point of Fill
Section or to the Most Appropriate Location in the Field.
• ALL Pipe Locations 1\1ay Slightly Varv Due. to Any Grade Changes in the Proposed Road~~°ay.
ALL Tempor~r~~ Rock Sediment Dams Shall Hai e C~~rc Fiber Baft7es Placed recording to
Specifications.
/ 0' to 10' tong will need 1 Battle
/ 10' to 20' Long will Need 2 Baffles
/ 20' and Longer will need 3 Baff]es
• If A'ou Have Questions Pertaining to the Erosion Control Design Contact David y~'avne at (336) 903-
9140 or Scott Pipes [phone].
• Again Note that Entire Design is Based ~'~round a 30 Day Construction Effort. Phasing IS CRITICAL.
