Approval of 401 Water Quality Certification with Additional Conditions
Dear Mrs. Lawhern:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 95 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 August 23, 2005. After
reviewing your application, we have decided these 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 that you described in your application. If you change
your project beyond this approval, 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

1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific
and general conditions of this Certification (or Isolated Wetland Permit) are met.
No other impacts are approved including incidental impacts:
Amount Plan Location or Reference
Approved (Units)
Stream 95 (feet) South 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.
Yancey County:

September 2, 2005
4. No Sediment & Erosion Control Measures wIn 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: Construction in this creek and disturbance within a 25-foot trout buffer should be
avoided during the January 1 to April 15 rainbow trout spawning period to avoid
adverse effects of sediment on eggs and larvae. However, Wildlife Resources
Commission will not object to construction of Natural Resources Conservation
Service "urgent and compelling" sites during the spawning period provided these
projects are, to the extent appropriate and practical, constructed by: (1) using flow
diversion structures such as sand bags, (2) placing large-sized rock toes and filter
cloth backing for stabilization sites before backfilling, and (3) excavating new
channel alignments in dry areas. Construction at the other non-"urgent and
compelling" sites should not occur during the spawning period to minimize the
potential adverse effects of multiple construction activities on trout resources in this
creek.
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. 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
djfficulty 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.
Yancey County:

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 fife 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.
9. The channel should 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. In 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 should not be permitted
because they block the floodplain, constrict and accelerate flood flows, and often fail
and sometimes 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 equjpnient 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. Disturbed stream banks and a 3D-foot vegetated zone (as required under the ORW
regulations), or the widest width that is practical under the site conditions, should be
restored where possible along the construction sites to natural riparian conditions
with native trees and shrubs (e.g., silky dogwood, rhododendron, dog hobble, red
maple, silky willow, tag alder, black willow, sycamore) to provide long-term bank
stability and stream shading. Note, silky dogwood, silky willow and black willow can
be planted as live stakes collected during the dormant growing season. Cuttings
should be randomly planted on four (4) foot centers from the waters edQ.e to the top
of the bank. Trees should be planted on ten (10) to twelve (12) foot centers. Stream

banks in these areas should also be seeded with a native annual and perennial seed
mix with a temporary nursery crop of wheat, millet or other grain.
i 14.lf pasture along the stream is to be used for grazing, a fence must be constructed
outside of the riparian zone and the stream to prevent livestock from entering these
areas. '
15. 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. If this is not
possible, it may be necessary to provide stormwater facilities that are considered
to remove nitrogen. This may require additional approval from this Office.
16. Riparian Zone Replanting
Replanting of vegetation within disturbed areas located within 30 feet of the
streambank associated with any land disturbing activity, repair, replacement
and/or maintenance must be done in a manner consistant with the Guidelines
for Riparian Buffer Restoration immediately following construction. (Please
see attached.)
i 45, Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands, waters and protective woody riparian zones in order to
assure compliance for future wetland, water and buffer impact. These
mechanisms shall be put in place prior to impacting any wetlands, waters and/or
buffers approved for impact under this Certification Approval and Authorization
Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site athttp://h20.enr.state.nc.us/ncwetlands. The text of
the sample deed notification may be modified as appropriate to suit to this
project.
17. Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 28. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
18. No Sediment and Erosion Control Measures in Wetlands
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 C?r locally delegated program has released the project.

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 of residential forestland and
agricultural uses. This area of Rock Creek was heavily impacted during Tropical Storms
Frances and Ivan. Severe streambank erosion and channel relocation threatens the stability
of adjacent properties and structures.
8. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Notification (PCN) form addresses one area of EWP repair activity on
. Rock Creek (see Figure 1) within the area known as DSR 44. Additional repairs within DSR 44
will be addressed in separate submittals.
During the flooding associated with Tropical Storms Frances and Ivan large woody debris
created a blockage in the channel approximately 150 feet upstream from the confluence of Rocky
Creek and South Toe River. The blockage facilitated the deposition of river rock. The channel
eventually filled with rock to the top of bank, it then overtopped the bank and is currently flowing
overland through a densely forested area. The resulting undefinedflow results in ongoing
erosion and sedimentation of the South Toe River.
Total disturbed areafor the channel relocation area is less than I-acre. Since the total
disturbed area is less than the Erosion and Sediment Control Plan permitting threshold of 1
acre, aformal approval of the Erosion and Sediment Control Plan elements of this proposal is
not needed. However, the proposed riparian area disturbance is less than the permitting
threshold of 100 linear feet, so a Trout Waiver will not be appliedfor.
All work will be performed as per conversations between Altamont Environmental, US Army
Corps of Engineers, NC Wildlife Resources Commission, and on-site consultation with the US
Fish and Wildlife Service personnel on other EWP sites in this watershed. Work will include
stream bank stabilization in the area described below as well as localized removal of organic and
mineral debris and stream bank re-vegetation.
Rock Creek is classified as 'Class C', 'Trout' and Outstanding Resource Waters (ORW)
throughout the project area. No listed species or their habitats occur in this area according to
the US Fish and Wildlife Service response to the EWP Environmental Checklist on February 2,
2005.
The following activities are proposed in the project area:
1) Rock debris will be removedfrom approximately 95 linear feet of channel to allow water to
return to its pre-flood location.
2) Removal of organic, mineral, and non-native material from areas where the hydraulic
capacity of the stream channel has been reduced based upon evaluation ojexisting cross-
sections and regional curves.
3) Softening of minor over-steepened banks and riparian planting.
3
Work lrill include: stream 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.
Dze general location of the stream bank repair area is provided in Figures 1 & 2.
Representati....e photosfrom these areas are included as Figures 3 - 4. Repairsfor each of the
srreambank stabilization sites are detailed in Figures 3A - 4A.
Streamhallk Stahilizatkm
Srreambank stabilization is needed on approximately 95 feet of banks within the project area.
StabilizaTion is required at the one distinct location shown in Figure 2.
Repair at the area will generally include stabilizing the bank in its current location. A key in
trench will be excavated on 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 nawral 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. TVhere sufficient space is available a banlifull bench
lrill be constructed in the fill area to increase hydraulic capacity and enhance future bank
stability. The area will be seeded lvith grasses upon completion of heavy equipment work. With
the landoH"/zer '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 fi'om 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 stream banks 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 Jfay 2, 2005, in anticipation of upcoming work under the EWP Program, the Board of
Commissioners ofJlitclzell County passed a resolution authorizing access to private land in
order to conduct EWP repairs. For this reason, individual Access Agreements are not
4
necessary for the work proposed in this PCN A copy of the resolution is attached to this
application. A summary of property owners is included as Table 1.
At the site, work shall proceedfrom downstream to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. Work 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 entrance/exits 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 coil' fiber or a coil' 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
stream banks 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 EWP program is not intended to fund stream restoration design or construction work.
Rather, the EWP program is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and possible loss of property or life. Because natural channel
design methods are beyond the scope of the EWP 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 usedfor stream bank stabilization or for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. Ifroot-wads are
used they will be installed so that at least 1/3 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 mix 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 channel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabriclsod-
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
5
planted throughout the project reach at a rate of 320 stems/acre, securing near bank areas and
providingfuture shading to the channel. Existing woody vegetation will be preserved to
minimi=e project impacts. The following steps .will be observed with respect to vegetation:
1. E'(posed soil will be covered with erosion control matting at the end of every workday.
JIats ,rill be secured using removable stakes.
2. The project riparian =one and/or buffer areas will be re-vegetated with a combination of
nati,'e trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary
natire grass mixture immediately following completion of the work in those areas. Tall
fescue will not be used in riparian areas.
3. 1Jt7ICn 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 acth'i!ies.
4. If sod is not available on-site temporary seeding will occur on all bare soil within five days
of ground dislllrbing 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 necessmy, 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.
Remul'al of Org(]Jzic (]JuJ Rocky Debris
TIle applicant recognizes that some woody debris in the riparian zone is a necessmy 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 hemy 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 ,vill instruct contractors performing the work to refrain from
cutting any lire vegetation unless it is leaning toward the river at more than a 3D-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 flood plain. In cases where it is determined that
large woody debris can be utilized in current or projectedfuture bank stabilization work, such as
in log vanes or as root ,rads, these articles may be stored on site out of the floodway 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.
RocJ...y debris within the flood plain and channel that reduces the hydraulic capacity of the
channel will be remOl'ed using an excm'ator. The removal of rocky debris will proceed from theAstream channel back tOli'ard the streambank allowing the excavator to work on the debris pile,
6
The reconfigured floodplain will be shaped in a manner intended to restore the hydraulic
capacity of the stream system. Rocky debris removed from the floodplain will be used to
stabilize the stream bank, 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 stream bank or will ,be hauled off site. In no case shall the deposited material be placed at an
elevation higher than the existing stream banks..
9. Explain the purpose of the proposed work:
The work being described is exigency work under the Emergency Watershed Protection program
to protect existing property and structures. Stream bank stabilization will also prevent further
erosion and sedimentation to the South Toe River resource.
