APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. J. J. Swain, Jr., P.E.
Division Engineer
N C Department of Transportation
Post Office Box 3279
Asheville, North Carolina 28802
Dear Mr. Swain:
You have our approval, in accordance with the attached conditions and those listed below, to impact 20 linear feet of two
(2) unnamed tributaries to the North Toe River and replace the culverts, without extension, at Stations 2+50 and 7+60,
both unnamed tributaries to the North Toe River (20 linear feet of new pipe, replace pipe at two (2) stream crossings and
temporary stream dewatering), in order to make improvements to NCSR 1186 (Johnson Road) in Mitchell County. The
project should be constructed in accordance with your application dated January 30, 2006 (received February 2, 2006),
including the environmental comments made in the application letter. 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. In addition, you must 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 in writing and submit a new application. If 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 if total impacts to streams (now
or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 211 .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. 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.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be
such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina
Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow
sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the
project.
c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual.

d. Any reclamation measures and implementation must comply with the reclamation in accordance with the
requirements of the Sedimentation Pollution Control Act.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the
impacts depicted in the Preconstruction Notice Application. All construction activities, including the design,
installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be
performed so that no violations of state water quality standards, statutes, or rules occur.
3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable.
If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed
and the natural grade restored within six months of the date that the Division of Land Quality has released the project.
4. Sediment and erosion control measures for sensitive watersheds [15A NCAC 04B .0124 (a)-(e)] must be used prior to
construction and maintained until any disturbed soils are permanently stabilized. Temporary or permanent
herbaceous vegetation. should be planted on all bare soil within fifteen (15) days of ground disturbing activities to
provide long-term erosion control. Erosion control mating should be used in conjunction with appropriate seeding on
disturbed soils in steep slope and.riparian areas. Matting should be secured in place with staples, stakes or wherever
possible, live stakes of native trees. Tall fescue should not be used in riparian areas. Riparian vegetation must be
reestablished within the construction limits of the project by the end of the growing season following completion of
construction.
5. Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater than 20% of their size to
allow for aquatic life passage. Culverts that are 48-inch diameter or larger should be buried at least 12 inches below
the stream bottom to allow natural stream bottom material to become established in the culvert following installation
and to provide aquatic life passage during periods of low flow. This may require increasing the size of the culvert to
meet flow conveyance requirements. If any of the existing pipes are perched, they shall be removed and replaced, and
re=installed correctly, unless demonstrated that this is topographically unfeasible.
6. Rock-check dams at culvert outlets should be removed at the project completion to. avoid impeding the movement. of
aquatic life.
7. The. dimension, pattern and profile of the stream, above and below the culverts, should not be modified by widening
the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural
geomorphic conditions.
8. Stormwater shall be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for
the purpose of pre-treating stormwater runoff, and must not be routed directly into streams. Mowing of existing
vegetated buffers is strongly discouraged, so that they may be utilized for stormwater diffuse flow.
9. Removal of vegetation at the stream crossings and adjacent to streams should be minimized. Native trees and shrubs
(e.g. Rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be
planted along the streambank to reestablish the riparian zone and to provide long-term erosion control in the vicinity
of the road crossing and along the streams within dedicated rights of way, if possible.
10. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and
vegetation should be used for stabilization above the high water elevation. Riprap should not be place in stream
channels in such a manner that it impedes aquatic life passage.
11. Heavy equipment should be operated from the bank rather than in the stream channels in order to minimize
sedimentation and to reduce the likelihood of introducing other pollutants into the stream. This equipment should be
inspected daily and maintained to prevent contamination of stream waters from leaking fuels, lubricants, hydraulic
fluids, or other toxic materials.
12. Excavation of the stream crossings and relocations should be conducted in the dry, if possible. Sandbags, cofferdams,
flexible pipe or other diversion structures should be used to minimize' excavation in flowing water.
13. If concrete is used during culvert construction (e.g., headwalls), a dry work area should be. maintained ,to, prevent
direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should
not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
14. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is
strictly prohibited.
15. The presence of equipment in the channels must be minimized. Under no circumstances must 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. In-stream dredging has catastrophic effects on aquatic life, and disturbance of the natural
form of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners.

16. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for
permitted areas associated with the culvert extensions.
17. All work shall be performed during low flow conditions (below bankfull).
18. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion " form
to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall
complete the attached form and return it to the Transportation Permitting Unit of the NC Division of Water Quality
upon completion of the project. The NCDOT is strongly advised to send in photographs upstream and downstream of
each structure to document correct installation.
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 Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.

Subject: Nationwide Permits #14 & # 33
SR 1186, Johnson Road
State Project No. 13C.061021 (DWQ Minor Permit Fee $200)
Mitchell County, NC
Dear Mr. Lund:
I have enclosed a straight-line diagram with erosion control plan, a PCN application for
NWP #14 & #33, and a vicinity map relative to the proposed project on SR 1186,
Johnston Road, Mitchell County, NC.'
Johnson Road is currently a 12 - 14 foot wide gravel road. Division of Highways plans to
pave a majority of the road at the existing width; however, the typical section will be
increased where possible to improve road safety. Grading will be light.
We propose to extend two (2) pipe culverts on Unnamed Tributaries (UTs) to the North
Toe River. Total culvert extensions will be 20 linear feet. The UT of the North Toe
River at Site 1 is an approximately 2-3 foot wide creek with some evidence of riffle/pool
habitats, and cobblestone substrate. The UT of North Toe River at Site 2 is an
approximately 1 foot wide feature with some evidence of riffle/pool habitats and
cobblestone substrate. Both of the UTs at Site 1 and Site 2 cross beneath the adjacent
railroad tracks prior to crossing beneath Johnson Road. We additionally propose to
replace two pipes at existing tributary crossings.
No stream relocation will be performed for the project. Existing channel morphology
will be maintained upstream and downstream of the culverts. The culverts will be placed
below existing streambed elevation. Riparian vegetation will be reestablished along
disturbed areas associated with the culvert extensions. Stormwater will be diverted
through grass-lined ditches or vegetated buffers prior to entering streams.

NCDOT requests by copy of this letter that US Fish and Wildlife Services evaluate the
project and we request concurrence on May Affect/ Not likely to Adversely Affect for the
Appalachian elktoe (Alasmidonta raveneliana). The culvert replacements are located
adjacent to the North Toe River, a known location for the Appalachian elktoe
(Alasmidonta raveneliana). The proposed project contains minimal in stream work
consisting of replacing two culverts on Unnamed Tributaries of the North Toe River and
replacing two existing culverts on Unnamed Tributaries of the North Toe River. High
Quality Water erosion control measures will be implemented to limit potential
sedimentation from the project.
As a part of the 401 Certification process, a copy of the application will be forwarded to
the NC State Historic Preservation Office as required by Section 106 of the National
Historic Preservation Act of 1966 and GS 121-12(a).
By copy of this letter, we request David McHenry, North Carolina Wildlife Resources
Commission Coordinator, to comment directly to the Corps concerning the permit
request.
By copy of this letter, we are asking Ed Ingle, Area Roadside Environmental Engineer, to
comment on the above project. Temporary encroachment into the buffer zone of the
North Toe River (Station 0+00 - Station 19+00) will be required for the entire project.
The UTs are classified as trout. A buffer variance will be required.
By copy of this letter, I am forwarding seven (7) copies of the application package to
Brian Wrenn, NC Division of Water Quality, 401/Wetland Unit and an additional copy to
Mike Parker, NC DWQ Asheville Regional Office for review and comment. Please
charge the application-processing fee of $200.00 to WBS element # 13C.061021. Please

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 secondary road
must be improved to meet current safety standards for raved roads. The pipe culvert extensions
requested are the minimum necessary to establish an appropriate typical section for the roadway.
The pipes to be replaced are damaged. Riparian vegetation will be established on disturbed areas
associated with the project 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 January 15, 2002, 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 NCEEP 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/strmEide.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,
Page 6 of 9
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.
We propose reforesting approximately 100 linear feet of NCDOT ROW along the North Toe
River as mitigation for the proposed impacts We propose to utilize native vegetation on
these areas of reforestation to help stabilize the banks adjacent to the road. We will utilize
Type 1 streambank reforestation as detailed on the attached stream reforestation detail sheet.
If this proposal is not acceptable we propose to utilize the Ecosystem Enhancement Program
(EEP) for the mitigation requirements for the proposed impacts. NCDOT will be
coordinating with the EEP to obtain the appropriate mitigation credits.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP

3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as. identified
within 15A NCAC 213.0242 or.0244, or.0260.
Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The existing compacted gavel roadway acts as
an impervious surface. Paving of the roadway should eliminate sedimentation from fines
associated with gavel surface treatment. The roadway surface will be 40% of right of way
acreage Stormwater will be diverted through settling basins or grass lined buffers prior to
entering the streams.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.

Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
ht!p://h2o.enr.state.nc.us/newetlands. If no, please provide a short narrative description:
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
With regard to hazardous mill basins, the road is not classified as an arterial route: therefore
hazardous spill basins are not required.

EROSION CONTROL PLAN SHEET
Generally, the order of installation of the erosion control measures will be as
follows: 41
Temporary silt basins shall be installed before clearing and
grubbing begins.
Silt fences and temporary silt ditches shall be installed after
clearing and before grading.
Temporary stone ditch checks shall be installed as soon as
ditch line is established.
Pipe outlet and inlet protection will be done as soon as the
pipe is installed.
Seeding and other permanent erosion control measures are
to be implemented as soon as practical. ,
Temporary rock silt checks (type B) will be spaced as required
by percent of grade as described on page VI-16 in the Erosion
And Sedimentation Guidelines.
No. 5 stone, or equivalent, will be used in conjunction with
temporary rock silt check Type-B in locations where water is
leaving the project or entering a pipe.
Silt basin size is 9'x3'x2' for 75 feet of disturbed ditch line unless otherwise
noted.
I8D4
Silt basin (Type B) are designed for 420ftubic feet per acre every storm event
and cleaned out when half full.
Per permit conditions for Corps of Engineers and the Wildlife Resources
Commission, all pipes in streams must be buried 12" below streambed
elevation.

PIPE INSTALLATION NOTES
4
1) Install erosion control devices. In streams, where necessary, rock silt
screen will be used.
2) Remove material and existing pipe while limiting, as much as possible,
material and sediment from entering the stream and/or escaping from project.
3) Prepare pipe foundation while again taking care to limit, as much as possible
material and sediment from entering the stream and/or escaping from project.
Where possible, new grade will be below existing streambed. If needed,
bedding material will be clean stone.
4) Place the new pipe and compact backfill.
5) Install slope protection on outlet and inlet ends of pipe. Also complete
installation of erosion control measures and perform maintenance as needed
on existing measures.
6) Establish permanent vegetation as soon as possible.

Asheville Field Office
FROM: Ron Linville Regional Coordinator xp?
Habitat Conservation Program
DATE: February 7, 2006
SUBJECT: North Carolina Department of Transportation (NCDOT), SRI 186, Johnson Road,
Unnamed Tributaries North Toe River, Mitchell County
NCDOT proposes to replace and/or extend culverts on SRI 186. Biologists with the North
Carolina Wildlife Resources. Commission are familiar with habitat values in the 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 North Carolina Environmental
Policy Act (G.S. 113A -I through 113A-10; NCAC 25). Removal of the existing bridge will not
impact waters.
The project involves extending two culverts by ten (10) feet each and removing and replacing
(R&R) two culverts. All three culverts are associated with tributaries of the North Toe River and
its floodplain. The North Toe in the project area supports populations of the Appalachian elktoe,
Alasmidonta ravenehana (NCE, FE).
Based on our review of the submittal, we will not object to the project provided the following
non-prioritized conditions are implemented:
1. The USFWS must concur with the project pursuant to requirements of the US
Endangered Species Act. We recommend that before doing any in channel work
where suitable mussel habitats are present, the streams should be surveyed for
mussels. If any mussels are found in the work area, they must be relocated by fully
authorized and properly trained biologists.
2. Culverts 48" or larger should be buried approximately V into the streambed.
Culverts less than 48 inches in 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.

Telephone: [phone] • Fax: [phone]
ti SRI 186, Johnson Road, North Toe Raver -Page 2 - February 7, 2006
3. The dimension, pattern, and profile of the stream above and below the crossings
should not be modified by widening the stream channels or reducing the depth of the
streams. Where practicable, floodplain benching must be restored or maintained to
ensure water depth and to restrict the width of the base flow channel.
4. Any riprap used must not interfere with aquatic life passage during low flow
conditions.
5. 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.
6. 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.
7. Heavy equipment should be new or low-hour, clean and well maintained. Spill
containment materials should be readily available on the site for use should any
petroleum spillage occur.
8. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion. Sediment and erosion control measures shall
adhere to the design standards for sensitive watersheds (15A NCAC 4B .0124).
9. Temporary or permanent herbaceous vegetation should be planted on all bare soil
within five (5) days or less if possible of ground disturbing activities to provide long-
term erosion control. Any vegetation removal and land disturbance must be
accomplished concurrently. We encourage NCDOT to utilize onsite vegetation and
materials for streambank stabilization when practicable.
10. As indicated, NCDOT should restore an undisturbed forested buffer along the North
Toe River.
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 3361769-9453.
