Approval of 401 Water Quality Certification with Additional Con di4trup. WATER QUALITY
%ETLANDS A140 STOPJAVATER BRANCH
Dear Mr. Nicholson:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 2,625 feet of streams for the purpose of
streambank stabilization and woody debris / trash removal, at the subject properties, as
described within your application received by the N.C. Division of Water Quality (DWQ)
on August 31, 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 that you described in your application. As "stable"
and "pre-storm" are not interchangeable terms, all work must be to ensure
stability, regardless of channel location. Additionally, channels cannot be
returned to it's pre-storm location unless there is documented instability is
submitted and approved as part of the application package. If you change your
project beyond the activities authorized below, 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:
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 2,625 (feet) North Fork, South -Fork & Mills
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.
Henderson County:
Page 3 of 6
September 9, 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. 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.
7. 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.
8. The channel must be restored to a more stable condition. However, under no
circumstances should river rock, sand or other materials be dredged (excavated)
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 re-establishing the natural and more

stable stream channel dimensions. Streambed 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.
9. 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.
10. 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.
11. 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.
12. Riparian Zone Replanting
Replanting of vegetation within disturbed areas located within 25 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.)Guidelines for Riparian Buffer Restoration.
(http://h2o.enr.state.nc.us/wra/odf/buffers.ndf 1
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.
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.
Henderson County:
Page 5 of 6
September 9, 2005
13. 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.
14. 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.
15. 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.

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 proposed projects will
take place within areas impacted by hurricanes during 2004.
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.
Page 5 of 5
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://ii2o.enr.state.nc.us/ncwetlands/strmgide.htini.
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. No mitigation is proposed for this project
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

Emergency Watershed Protection Program
Henderson County, North Carolina
Mills River, South Fork Mills River, North Fork Mills River
Nine stream reaches on three stream channels are being targeted for repair under the Emergency
Watershed Protection program. The three stream channels are Mills River (five reaches), North
Fork Mills River (two reaches), and South Fork Mills River (two reaches). At the request of the
U.S. Fish and Wildlife Service (USFWS), in-stream surveys for the federally Endangered
species, Appalachian elktoe (Alasrnidonta raveneliana) were conducted within these stream
channels. A separate report outlining the findings of this effort was submitted to the USFWS
and the U.S.D.A. Natural Resources Conservation Service. Each project is briefly described
below.
Mills River
Five stream reaches of Mills River are targeted for repair.
Two sites (42, 43) are located on the reach of Mills River between the City of Hendersonville
Water Supply Intake located 0.1 mile downstream of NC 191 and a point 0.7 mile upstream of
the mouth of Mills River, which has a Best Usage Classification of WS-III, and is not a
designated Trout water.
One site (Site 131) is located on the reach of Mills River between its source and a point 0.5 mile
upstream the NC 191 has a Best Usage Classification of WS-II;Tr;HQW, and is a designated
Trout water.
Two sites (149, 151) are located on the reach of Mills River between a point 0.5 mile upstream
of NC 191 and the City of Hendersonville Water Supply Intake located 0.1 mile downstream of
NC 191, which has a Best Usage Classification of WS-II;Tr;HQW;CA and is a designated Trout
water.
A brief description of each project follows.
Site 42 is approximately 400 linear feet in length. Proposed work for this reach includes debris
removal, bank stabilization and revegetation. Deflector stones will be utilized to protect stream
banks. Mussel surveys conducted in this reach produced no Appalachian elktoe, but did produce
36 live slipper shells (Alasmidonta viridis). A tagged, live Appalachian elktoe was noted
upstream of this reach during a separate survey effort. Consultation with USFWS will be
required for this site. Adjacent land use for this reach includes commercial agriculture and
residential yards.
Site 43 is approximately 400 linear feet in length. Proposed work for this reach includes bank
stabilization and revegetation. Deflector stones will be utilized to protect stream banks. Mussel
surveys conducted in this reach produced no Appalachian elktoe, but did produce 11 live slipper
shells. Consultation with USFWS will be required for this site. Adjacent land use for this reach
includes commercial agriculture.
Site 131 is approximately 100 linear feet in length. Proposed work for this reach includes debris
removal, bank stabilization and revegetation. As part of this work, a gravel bar will be removed.
Surveys were conducted within this reach for Appalachian elktoe. No individuals of this species
were noted, however, one live slipper shell was noted. The site is potentially suitable habitat for
Appalachian elktoe and will require on-site consultation with the USFWS. Adjacent land use for
this reach includes commercial agriculture.
Site 149 is approximately 250 linear feet in length. Proposed work for this reach includes debris
removal, bank stabilization and revegetation. Deflector stones will be utilized to protect stream
banks. Mussel surveys within this reach produced one live Appalachian elktoe and 21 live
slipper shells. Consultation with USFWS will be required for this site. Adjacent land use for
this reach includes commercial agriculture.
Site 151 is approximately 275 linear feet in length. Proposed work for this reach includes debris
removal, bank stabilization and revegetation, and removal of a gravel bar. Mussel surveys
within this reach produced on live, tagged Appalachian elktoe (Tag No. A-186) located
approximately 400 meters downstream of the repair area. Consultation with USFWS will be
required for this site. Adjacent land use for this reach includes commercial agriculture.
North Fork Mills River
Two stream reaches on the North Fork Mills River are targeted for repair. These areas are
located on the reach of North Fork Mills River, between the North Fork Mills River Recreation
Area Swimming Pool intake and Mills River, which has a Best Usage Classification of WS-
II;Tr;HQW and is a designated Trout water. A brief description of each project follows.
Site 129 is approximately 200 linear feet in length. Proposed work for this reach includes debris
removal, removal of gravel bars, bank stabilization and revegetation. Deflector stones will be
utilized to protect stream banks. Mussel surveys conducted within this reach produced no
evidence of any mussel species. Adjacent land use for this reach includes commercial
agriculture.
Site 130 is approximately 100 linear feet in length. Proposed work for this reach includes bank
stabilization and revegetation. Deflector stones will be utilized to protect stream banks. Mussel
surveys conducted within this reach produced no evidence of any mussel species. Adjacent land
use for this reach includes forested areas.
South Fork Mills River
Two reaches of South Fork Mills River are targeted for repair. These areas are located on the
reach of South Fork Mills River between the upstream side of the mouth of Queens Creek to
Mills River, which has a Best Usage Classification of C;Tr;HQW, and is a designated Trout
water. A brief description of each project follows.
Site 45 is approximately 600 linear feet in length. Proposed work for this reach includes debris
removal, bank stabilization and revegetation, and installation of one in-stream structure (J-hook).
Mussel surveys conducted within this reach did not produce evidence of any mussel species.
Adjacent land use for this reach includes commercial agriculture.
Site 46 is approximately 300 linear feet in length. Proposed work for this reach includes bank
stabilization and revegetation, and installation of two in-stream structures (cross vanes). Mussel
surveys conducted in this reach produced no evidence of any mussel species. Adjacent land use
for this reach includes commercial agriculture.

There could be difficulty in spreading Big Bluestein seed with a hand held centri0tgal
seeder because efarough seed coat, light density andthepresence ofawms. This species
could be dropped from the mixture or spread separately by hand.
• These are to be used as temporary cover and the following is provided as a guide to
assist in making the decision where to use each and when to use them.
• Japanese and Foxtail Millet are to be used as temporary cover ally June I. Ei [her
may be used or they may be used together at half the normal rate when used
singularly. Choose Japanese Millet on wctsites and FoxtailMillet on dnsites. If
the site is characterized by both moisture regimes and separating the plant
selection proves to be impractical, then use the mix.
• Objections may be raised to using either plant due to non-nativity. Japanese
millet does have the potential to be a wad. If there is an objection to Japanese
Millet drop it from the specification and select Foxtail Millet as a substitute.
Foxtail Millet does not have the potential to become a weed and is in the same
category of usefulnar as a cool season small grain.
• Select Oats or Rye as the temporary cover after August 1. Oats have a slightly
better chance at providing useful cover on wetter sites than does Rye. These may
be selected singularly or in a mix combined at half the singular rate for each to
make a full seeding application tale.
• All seeding applications shall include temporary cover mixtures.
