Subject: Nationwide Permit 414
SR 1300 (B. H. Duncan Road)
Ashe County, North Carolina
Project Number: 11C.005112 (DWQ Permit Fee: $570)
Dear Mr. Matthews:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1300, B. H.
Duncan Road in Ashe County. Total project length is approximately 0.3 miles. The improved
section will be widened from 14 feet to 18 feet with impervious surface area increasing by 0.15
acres. This project will require the replacement of three wet pipes and the addition of two wet
pipes as shown below:
Stream Impacts:

this Station ft.

7+98 22'x 18" 90'x 24" 10 78

13+89 None 50'x 18" 10 60
15+55 28'x 18" 55'x 24" 10 37

Total Stream Impacts = 285 feet
Please note that all of these wet pipes carry 1' wide drainage from either wetlands or a spring.
The last 4 pipes are perched and likely will remain perched due to slope. The pipes at stations

13+00 and 13+89 were added to eliminate/reduce wet ditch flow emanating from the adjacent
wetland areas.
The replacement of the above noted wet pipes will require 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 all wet pipe replacement areas will be approximately
0.008 acres. Once the new pipes are in place, the impervious dikes will be removed and
preconstruction streambed elevations will be restored.
The wet pipes in question carry different unnamed tributaries to Wallace Branch (Class: C, Trout
+). This project was reviewed for the presence of threatened and endangered species on July 21,
2008. This project will have no effect on any federally listed endangered plant or animal species.
There is one property along the roadway that may have some historical significance. Additional
historic compliance work will be scheduled and concurrence with the State Historic Preservation
Office will be obtained prior to construction in this area.
In addition to the above noted piping impacts, there are several wetlands located adjacent to the
roadway that will be impacted at stations 8+00 (Lt.), 11+00 (Rt. & Lt.) and 13+00 (Rt. & Lt.).
Total impacts will be .12 acres. These areas are basically wet pasture patches dominated by
Juncus spp. with no canopy.
The project impacts are not significant 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. Note that we will be working within the
trout buffer zone of Wallace Branch from stations 0+00 - 8+00 (Rt.) and 13+00 - 16+32 (Rt.).
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.
Mr. Monte Matthews

NOTES FOR EROSION CONTROL PLAN
• Each Section under Construction shall be Seeded and Mulched within 30 Davs after Grubbing
Begins (Per STEP # 7 of the Erosion Control Design). See Phasing Sheet on Next Page for
Section Layouts.
• Temporary Kock Sediment Dam, Tvpe-B Used at ALL Locations as Shown. Please Pay Close
Attention to the Sizing, Some TRSD-B's are Greater/Smaller in Size than others. All TRSD-B's
are Designed on a 3 to L 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. A copy of the Designer Spreadsheets Hill be forwarded electronically to
the appropriate County Unit.
• 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 mac need to
be installed :Tong Silt Fence in Accordance with the Topographv of the Construction Limits.
• ALL. Pipe Locations May Slightly Vary Due to Any Grade Changes in the Proposed Roadway.
• .ALL Temporary Rock Sediment Danis 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].
• Wattles and PAR1 are required only for FIQ«', ORW, & Trout Water sheds. These type devices
are noted on EC plans with the appropriate symbol. Always apply PAM to any installed wattle.
Further installation clarification can be viewed on the Roadside Environmental website.
• Again rote that Entire Design is based around a 30 Day Construction Effort. Phasing IS
CRITICAL.
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

shorter, except as provided in 15A NCAC 413.0024 (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.
CONSTRUCTION SEQUENCE FOR INSTALLING ROADWAY
CULVERTS
1 - Clear only enough area and install the downstream measures such
as silt check dams, silt screens, and basins as noted on plans.
2 - Excavate the 2' base tail ditch.
3 - Excavate and install the roadway culvert.
4 - Install sediment control measures at inlet as noted on plans.
5 - Install additional pipe outlet protection and inlet protection as
noted.
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 constricted 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 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.
