Subject: Nationwide Permit #14
SR I I69B (West Pine Swamp Road)
Ashe County, North Carolina
Project Number: 11C.005078 (DWQ Permit Fee: $240)
Dear Mr. Matthews:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1169B, West Pine
Swamp Road in Ashe County. Total project length is approximately 0.78 miles. The improved section
will be widened from 16 feet to 18 feet with impervious surface area increasing by 0.19 acres. This project
will require 0.03 acres of wetland fill adjacent to station 15+50 (It.) as well as the replacement of four wet
pipes as shown below:

Total Stream Impacts =130 feet
There appears to be a spring located under the existing road at this location. A 6" plastic under drain
pipe is stubbed out of our fill but the pipe inlet can't be located. There is no stream channel on the cut
slope side so dewatering this site by traditional methods is not possible. Since there is no channel up
slope, there is no reason to bury this pipe extension. As a result, sedimentation impacts associated with
this pipe replacement should be minimal. We will install a rock silt check in the channel downstream of
the road. This class B stone and gravel will be placed on top of geotextile fabric so that it can all be
reclaimed after turbidity levels stabilize,

The replacement of the remaining wet pipes will require traditional temporary dewatering. An impervious
sandbag dike will be constructed upstream of the existing culverts to create a small pool. Clean water will
temporarily be pumped around the construction areas and will be discharged downstream. Any dirty water
located inside of the construction areas will be pumped into a silt bag if necessary. Total dewatered area
for these wet pipe replacement areas will be approximately 0.024 acres. Once the new pipes are in place,
the impervious dikes will be removed and preconstruction streambed elevations will be restored.
The wet pipe at station 16+55 carries the West Fork of Pine Swamp Creek (Class: C, Trout +). The
remaining wet pipes carry different unnamed tributaries to the West Fork of Pine Swamp Creek. This
project was reviewed for the presence of threatened and endangered species on May 13, 2008. 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 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. Please note. that a trout buffer variance will be requested for land
disturbance activities near station 15+50 (lt.).
By copy of this letter, I am forwarding five (5) copies of this application package to Brian Wrenn,
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,
Heath Slaughter
Division Environmental Officer

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 ping len hs will be the minimum needed to
safely construct the paved roadway All appropriate BN4Ps 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 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.state.nc.us/ncwetlands/strmgide.html.
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.

SECTION 1042
RIP RAP MATERIALS
1042-1 PLAIN RIP RAP
Stone for plain rip rap shall consist of field stone or rough
unhewn quarry stone. The stone shall 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 shall 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 shalt 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 storm.
4. Newly constructed channels shall be constructed with side slopes no
steeper than 2:1, unless slopes are to be stabilized by methods other than
vegetation
5. A ground cover sufficient to restrain erosion must be provided for any
disturbed area.

NOTES FOR EROSION CONTROL PLAN
• Each Section Under Construction Shall be Seeded and Mulched Within 30 Days After Grubbing
Begins (Per STEP # 7 of the Erosion Control Design). See Phasing Sheet on Next Page for Section
Layouts.
• 9' X 3' X 2' Temporary Rock Sediment Dam, Type-B Used at Most ALL Locations as Shown. ALL
are Greater Than or Equal to the Required Storage Given in STEP # 7 of the Designer Spreadsheet.
Please Pay Close Attention to the Sizing, Some TRSD-B's are Greater in Size. All TRSD-B's are
Designed on a 3 to 1 Length to Width Ratio.
• 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. More Outlets Devices may need to be
Installed Along Silt Fence in Accordance with the Topography of the Construction Limits.
• ALL Pipe Locations May Slightly Vary Due to Any Grade Changes in the Proposed Roadway.
• ALL Temporary Rock Sediment Dams Shall Have Core Fiber Baffles Placed According to
Specifications.
? 0' to 10' Long will need 1 Baffle
? 10' to 20' Long will Need 2 Baffles
? 20' and Longer will need 3 Baffles
• If You Have Questions Pertaining to the Erosion Control Design Contact David Wayne at (336) 903-
9140 or Scott Pipes [phone].
• Again Note that Entire Design is Based Around a 30 Day Construction Effort. Phasing IS CRITICAL.
• We will now be using wattles with PAM on all Trout and HQW waters. On the REU website you will
find an installation and spacing guide. Use PAM 705. This will be mandated on all ditchline and pipe
sections that drain directly into the Trout/HQW stream. See E/C Plans for further reference.

Revised 41912008
EROSION CONTROL SCHEDULE
(1) All adequate temporary erosion control measures will be installed before
clearing and grubbing operations begin.
(2) As construction progresses, temporary and permanent erosion
control devices shall be installed in a timely matter, according to
any special permit requirements and or requirements set out in
G.S. 113A-57.
MANDATORY STANDARDS FOR LAND-DISTURBING ACTIVITY
Pursuant to G.S. 113A-57 (3), Provisions for a ground cover
sufficient to restrain erosion must be accomplished within 30
working days or 120 calendar days following completion of
construction or development, whichever period is shorter, except as
provided in 15A NCAC 4B .0024 (e).
DESIGN STANDARDS IN SENSITIVE WATERSHEDS
Pursuant to G. S. 113A-57 (3) provisions for a ground cover
sufficient to restrain erosion must be provided for any portion of a
land-disturbing activity in a HQW zone within 15 working days or
60 calendar days following completion of construction or
development, whichever period is shorter.
(3) All siltation and erosion control devices shall be properly maintained until
no longer needed.
(4) On projects performed by D. 0. T. Maintenance Forces, request will
promptly be made to the Division Roadside Environmental Unit for stage
and permanent seeding.
(5) Any removal of siltation devices will be based on the condition of
established ground cover of that area the device is serving.
