Approval of 401 Water Quality Certification with Additional Conditions
Dear Mrs. Young:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 690 feet of streams for the purpose of
streambank stabilization at the subject properties, as described within your application
received by the N.C. Division of Water Quality (DWQ) on July 8, 2005. After reviewing
your application, we have decided that the impacts are covered by General Water
Quality Certification Number(s) 3376 (3376). The Certification(s) allows you to use
Nationwide Permit(s) 37 when issued by the US Army Corps of Engineers (USACE). In
addition, you should obtain or otherwise comply with any other required federal, state or
local permits before you go ahead with your project including (but not limited to) Erosion
and Sediment Control, Non-discharge, and stormwater regulations. Also, this
approval to proceed with your proposed impacts or to conduct impacts to waters
as depicted in your application shall expire upon expiration of the 404 or CAMA
Permit.
This approval is for the purpose and design that you described in your application. If
you change your project, you must notify us and you may be required to send us 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
conditions. If total fills for this project (now or in the future) exceed one acre of wetland
or 150 linear feet of stream, compensatory mitigation may be required as described in
15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in
the attached certification and any additional conditions listed below.
The Additional Conditions of the Certification are:

Amount
Approved Units Plan Location or Reference
Stream 690 feet North Toe River
2. Erosion & Sediment Control Practices
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. The reclamation measures and implementation must comply with the
reclamation in accordance with the requirements of the Sedimentation
Pollution Control Act.
3. No Waste, Spoil, Solids, or Fill of Any Kind.
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 Pre-Construction
Notification. 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.
Mitchell County:
Page 3 of 6
July 18, 2005
4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
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
Resources has released the project.
5. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification
or applicable Buffer Rules, and any subsequent modifications, the applicant is
required to return the attached certificate of completion to the 401/Wetlands Unit,
North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC,
27699-1650.
6. North Toe River is classified C, Trout. As such, the following Administrative Codes
apply: 15A NCAC 04B.0125 and 15A NCAC 0213.0211
7. Sediment and erosion control measures must be implemented prior to construction
and maintained on the sites to minimize sediment in downstream areas. Seeding for
a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous
cover should occur on all bare soil within five (5) days of ground disturbing activities
to provide long-term erosion control. The projects should be accomplished in stages
instead of leaving large tracts exposed to further storm events. Erosion control
matting should be used in conjunction with appropriate seeding on disturbed soils in
steep slope and riparian areas, unless authorized under Division of Land Resources
Erosion and Sediment Control approval. Matting should be secured in place with
staples, stakes, or, wherever possible, live stakes of native trees. Straw mulch and
tall fescue should not be used in riparian areas. In addition, because of an
anticipated difficulty in establishing ground cover during the winter, reseeding should
be conducted, as necessary, in the spring-time with a native annual and perennial
seed mix with a temporary nursery crop of wheat, millet or other grain.
8. Only clean, large, angular rock, large woody material, or other natural stream design
materials and techniques should be used for bank stabilization. Rock should not be
placed in the stream channel in a manner that constricts stream flow or that will
impede aquatic life movements during low flow conditions. Filter cloth should be
placed behind large rock that is used for bank stabilization. Properly designed rock
vanes should be constructed wherever appropriate on bank stabilization and
channel realignment stream reaches to improve channel stability and to improve
aquatic habitat. Root wads should be installed low enough in the bank so that a
significant portion (at least one-third) the root wad is inundated during normal flows.
Mitchell County:

July 18, 2005
9. The channel must be restored to a more stable condition. However, under no
circumstances should river rock, sand or other materials be dredged from the stream
channel under authorization of this permit except, if necessary, in the immediate
vicinity of the eroding banks for the explicit purpose of anchoring stabilizing or
flow/grade control structures or for reestablishing the natural and more stable stream
channel dimensions. Stream bed materials are unstable in flowing-water situations
and are unsuitable for bank stabilization. Stream dredging has catastrophic effects
on aquatic life and disturbance of the natural form of the stream channel can cause
downstream erosion problems. The natural dimension, pattern, and profile of the
stream upstream and downstream of the permitted area should not be modified by
widening the stream channel or changing its depth.
10. Stabilization measures should only be applied on or near existing erosion sites,
leaving other stable stream bank areas in a natural condition. Grading and
backfilling should be minimized and tree and shrub growth should be retained where
possible to ensure long term availability of stream bank cover for aquatic life and
wildlife. Backfill materials should be obtained from upland sites except in cases
where excess stream bed materials are available. Berms are not permitted because
they block the floodplain, constrict and accelerate flood flows, and often fail or
impede drainage during large flood events.
11. Repairs to eroded banks should be conducted in a dry work area where possible.
Sandbags or other clean diversion structures should be used where possible to
minimize excavation in flowing water. Channel realignments should be constructed
by excavating the new channel from downstream to upstream before connecting it to
the old channel.
12. Heavy equipment should be operated from the bank whenever possible. All
mechanized equipment operated near surface waters should be inspected and
maintained regularly to prevent contamination of stream waters from fuels,
lubricants, hydraulic fluids or other toxic materials. Equipment used in stream
channel must be clean, new or low hour equipment.
13.As long-term stream stability is a concern with this type of work, it is strongly
recommended that woody vegetation be established along stream banks where
possible. Any riparian vegetation planting should be performed in accordance with
the Guidelines for Riparian Buffer Restoration.
(htto://h2o.enr.state.nc.us/wro/odf/buffers.odf )
13. Monitoring
The Permittee shall examine the stabilization work done under this Certification
on an annual basis for three (3) years following the completion of the restoration
efforts. This field evaluation should note the condition and stability of the
measures installed and how well the repair is holding up. A written report must
be provided to DWQ's Asheville Regional Office by June 1St of each year. The
report must describe inspection results, include digital photographs, list the date
of inspection, and describe any needed repairs or corrections.
F
14.The permittee will provide on-site supervision of stability work including, but not
limited to bank re-sloping, in-stream structure placement, and riparian zone re-
establishment, by an appropriately trained individual.
Mitchell County:
Page 5 of 6
July 18, 2005
15. If pasture along the stream is to be used for grazing, the permittee must inform the
appropriate landowners that cattle should be prohibited from damaging riparian
areas and from de-stabilizing the stream banks and channel.
16. Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained
as diffuse flow at non-erosive velocities through the protected riparian zones
such that it will not re-concentrate before discharging into a stream.
17.Water Quality Certification Notifications
The permittee must provide a copy of this issued Water Quality Certification and
attached cover letter to each property owner where the approved work will be
performed.
18.Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
Violations of any condition herein set forth may result in revocation of this Certification
and may result in criminal and/or civil penalties. The authorization to proceed with your
proposed impacts or to conduct impacts to waters as depicted in your application and
as authorized by this Certification, shall expire upon expiration of the 404 or CAMA
Permit.
If you do not accept any of the conditions of this Certification (associated with the
approved wetland or stream impacts), 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.

9. Describe the existing conditions on the site and general land use in the vicinity of the project at
the time of this application:
Land use in the vicinity of the proposed project site consists ofprimarily residential and
agricultural uses. Portions of the North Toe River were heavily impacted during Tropical
Storms Frances and Ivan. In numerous locations, the river is clogged with woody and non-
native debris, reducing the hydraulic capacity of the channel. Additionally, three areas of
streambank erosion threaten the stability of adjacent properties and structures.
10. Describe the overall project in detail, including the type of equipment to be used:
The EJVP project area known as DSR No. M2004-13 is addressed by this permit application.
The project area consists of the North Toe River and its tributaries. The total estimated
disturbed area for activities covered under this PCN is approximately 0.9 acres. Since this is
less than the Erosion and Sediment Control Plan permitting threshold of I acre, a formal
approval of the Erosion and Sedinrerrt Control Plan elements of this proposal is not needed.
However, the total disturbed length of the buffer area for Work Areas # 1 and # 3 is more than
100 feet, therefore a formal request for a Trout waiver is being submitted.
The North Toe River is classified as `Class C' and Trout' waters throughout the project area.
The following activities are proposed in the project area:
1) Three distinct areas in need of stream bank stabilization have been identified, totaling
approximately 690 linear feet. High water flow has severely eroded stream banks in these
areas. In places, the riverbanks are over-steepened and very unstable, threatening
structures acrd property. Repairs in these areas will involve the following:
• Stabilize the channel in its post flood configuration using organic and rock structures.
• Stabilize the river banks by: removing unstable vegetation; stabilizing the toe of the
slope where necessary by placing large angular stone just above the water level, or by
the use offiber logs; backfrlling behind and above the stone with rocky debris removed
ftorn the floodplain or imported to the site; topping with planting media acrd planting
native vegetation.
2) Removal of organic, inineral, and non-native material from areas where the hydraulic
capacity of the stream channel has been reduced based upon evaluation of existing cross-
sections and regional curves.
3) Softening of rrrirror over-steepened banks acrd riparian plarrtirrg.
Work will include: strewn bank stabilization in several areas described below. Equipment
used to accomplish the above tasks includes: rubber tired skidders, 15 ton dump truck,
hydraulic track mounted excavator with thumb, and chainsaws.
The general location of the three stream batik repair areas is provided in Figures I - 4.
Representative photos front these areas are included as Figures 5 - 9. Repairs for each of the
areas are detailed in Figures 5A - 9A.
Streantbank Stabilization
Streanibank stabilization is needed oil approximately 690 feet of banks within the project area.
Stabilization is required at the three distinct locations shown in Figures 2 - 4.
Repairs at each of the three areas will generally include stabilizing the bank in its current
location. A key in trench will be excavated oil the outside of the curve at the base of the existing
slope as necessary. Large (three to four foot diameter) angular rock, large diameter logs
(greater than 2 feet), and/or natural fiber logs will be used to stabilize the toe of the bank at
high stress locations (e.g. the outside of bends). A second tier of material will be used, as
needed. The area behind the material will be backfilled with rocky debris material excavated
from the floodplain or imported material, and topsoil will be placed on the top of the
reconstructed bank to aid in the establishment of vegetation. Where sufficient space is
available a bankfull bench will be constructed in the fill area to increase hydraulic capacity and
enhance future bank stability. The area will be seeded with grasses upon completion of heavy
equipment work. With the landowner's permission, live stakes and bare root stock native trees
and shrubs will be planted on top of the bank stabilization work. In areas where high stress on
the toe is not expected (e.g. the inside of bends and straight sections with low banks), the use of
large material is not necessary, and logs or natural fiber logs will be used to provide the
necessary toe stabilization.
Work will be performed from the riverbank to the extent possible. In some locations, work will
occur in the dry above the normal water surface level. However, given the existing condition of
the stream bank and channel at these locations, it is likely that the stabilization of the toe of the
banks will occur in the wet. In such cases, sand bags, or the equivalent, will be used to deflect
water flow away from the work area, as well as prevent water from accumulating in the work
area. Standard erosion and sedimentation control measures, as subsequently described, will be
utilized throughout the project.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are threatening
structures. The proposed actions are not intended to enhance existing conditions or restore the
stream reaches using natural channel design techniques. Such activities would require detailed
engineering evaluation and design, which are beyond the intent of the EWP program.
On May 2, 2005, in anticipation of upcoming work under the EWP Program, the Board of
Commissioners of Mitchell County passed a resolution authorizing access to private land in
order to conduct EWP repairs. For this reason, individual Access Agreements are not
necessary for the work proposed in this PCN. A copy of the resolution is attached to this
application. A summary ofproperty owners is included as Table 1.

At the site, work shall proceed from downstream to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. TVork will proceed as follows at each work
area (as applicable):
1. Flag the work limits.
2. Mark live trees and shrubs to be protected.
3. Construct temporary construction entrancelexits where necessary.
4. Install sediment fence around staging areas.
5. At the end of each workday install erosion control matting on exposed soil using removable
stakes. Erosion control mats will be constructed of coir fiber or a coir fiber mixture fabric
for maximum erosion protection, vegetation establishment assistance, and for minimal
impact on wildlife.
6. During construction, place large boulders, logs, or fiber rolls at the toe of repaired
streambanks where necessary.
7. Fill and compact behind boulders, logs, or fiber rolls. Cover with topsoil, install erosion
control mat, and seed.
8. Inspect and maintain repairs.
A site-specific engineering design based on a specific storm event was not completed because
the EiVP program is not intended to fund stream restoration design or construction work.
Rather, the EIVP program is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and possible loss ofproperty or life. Because natural channel
design methods are beyond the scope of the EIVP program, published literature values were
consulted in order to specify the bank stabilization and erosion control materials and methods
described in this document. For example, we have specified that filter cloth will be placed
behind large rock used for streambank stabilization or for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. If root-wads are
used they will be installed so that at least 113 of the root is inundated during normal flows.
Clean, large, angular rock, large woody material, and natural fiber erosion control mats will be
used for streambank stabilization.
Once site construction has ceased, the banks of the restored channel will be seeded with a
native floodplain seed prix and the high stress areas will be lined with erosion control (EC)
matting to ensure bank stability. Furthermore, sod matting will be grubbed on-site and used
(when available) to line the near bank regions of the constructed/stabilized charnel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod-
matting in these high stress areas. Broadcast seeding rates will be as specified from the local
nursery, generally 15-20 lbs/acre depending on species. Native shrub and tree species will be
planted throughout the project reach at a rate of 320 stenns/acre, securing near bank areas and
providing fixture shading to tlne channel. Existing woody vegetation tivill be preserved io
minimize project impacts. The following steps will be observed with respect to vegetations:
1. Exposed soil will be covered with erosion control matting at the end of every workday.
Mats will be secured using removable stakes.
2. The project riparian zone and/or buffer areas will be re-vegetated with a combination of
native trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately following completion of the work in those areas. Tall
fescue will not be used in riparian areas.
3. When possible sod will be taken from adjacent areas (with landowner permission) and
placed on exposed soil to provide immediate stabilization within five days of ground
disturbing activities.
4. If sod is not available on-site temporary seeding will occur on all bare soil within five days
ofground disturbing activities to provide long-term erosion control. If sod is used, the bare
area left after removal of sod will be planted.
5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix
with a temporary nursery crop of wheat, millet, or other grain
6. Woody vegetation will be planted during the normal growing season assuming landowner
permission.
Renwval of Organic and Rocky Debris
The applicant recognizes that some woody debris in the riparian zone is a necessary component
of habitat integrity and will strive to remove only non-native objects and those debris elements
considered an immediate or impending threat to life and structures. Contractors performing
debris removal tasks will be instructed to access debris on both sides of the river from the bank
on which the debris is located. Contractors will be instructed specifically to keep heavy
equipment out of the river channel. In some circumstances, it is likely that chainsaw operators
or heavy equipment support personnel may need to get in the river to cut or help free debris jams
being removed. In addition, large debris being pulled from the riverbank may result in some
riverbank. scour. The applicant will instruct contractors performing the work to refrain from
cutting any live vegetation unless it is leaning toward the river at more than a 30-degree angle
and the river is entrenched or the riverbank is unstable at that point. Debris removed will be
hauled off site or chipped and disposed of in the food plain. In cases where it is determined that
large woody debris can be utilized in current or projected future bank stabilization work, such as
in log vanes or as root wads, these articles may be stored on site out of the foodway upon
landowner permission. All areas disturbed due to debris removal and equipment access will be
reshaped and reseeded. Access to the channel will be perpendicular to the channel. Precaution
will be taken to protect mast production and stream canopy trees. Dead trees that provide den
habitat and are determined to pose no hazard to the channel shall be protected.
Rocky debris within the food plain and channel that reduces the hydraulic capacity of the
charniiel will be removed using an excavator. The removal of rocky debris will proceed f 0772 the
stream channel back toward the streambank allowing the excavator to work on the debris pile.
The reconfigured (oodplain will be shaped in a manner intended to restore the hydraulic
capacity of the stream system. Rocky debris removed from the (oodplain will be used to
stabilize the streambank, or will be hauled offsite. At sites where there is no eroded streambank
in the immediate vicinity, the excavated material will be used to strengthen the natural berm of
the streambank or will be hauled off site. In no case shall the deposited material be placed at an
elevation higher than the existing streambanks.
11. Explain the purpose of the proposed work:
The work being described is exigency tivork under the Emergency JYatershed Protection program
to protect existing property and structures. Streambank stabilization will also prevent further
erosion and sedimentation to the North Toe River resource.
IV. Prior Project History

minimum necessary to allow for bank stabilization and debris removal sufficient to restore the
hydraulic capacity of the channel. Temporary grass cover shall be planted on all bare soil within
5 days ofground disturbing activities. Provided landowners give permission, herbaceous and
woody shrub and tree vegetation will also be installed on the riverbank upon completion of bank
stabilization work. Mitchell County will provide a site manager to routinely inspect and
supervise contractor work to help ensure impact avoidance instructions are being followed.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .05 00, 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.
