Approval of 401 Water Quality Certification with Additional Conditions
Dear Mr. Hilliard:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 73 linear feet of streams for the purpose of
stream stabilization at the subject property, as described within your application
received by the N.C. Division of Water Quality (DWQ) on May 1, 2006. After reviewing
your application, we have decided these impacts are covered by General Water Quality
Certification Number(s) 3494 (GC3494). The Certification (s) allows you to use
Nationwide Permit(s) 3 when issued by the US Army Corps of Engineers (USAGE). 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
Approved (Units) Plan Location or Reference
Stream 73(feet) N. 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.
North Hills Trail Bridge
Page 3 of 6
May 22, 2006
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. Construction in this creek and disturbance within a 25-foot trout buffer should be
avoided during the October 15 to April 15 trout spawning period to avoid adverse
effects of sediment on eggs and larvae.
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
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.
Should large, angular rock, large woody material, or other natural stream design
materials and techniques not be sufficient for long term stability of the stream and
adjacent roadway, and concrete be incorporated into the design, measures which
would prevent surface waters from coming into contact with live concrete.
North Hills Trail Bridge

May 22, 2006
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. No backfilling
of stream bed materials is allowed under this authorization.
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. Sandbags or
other clean diversion structures should be used 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. Exposure of equipment to
surface waters must be minimized to the maximum extent possible.
13. Disturbed stream banks and a 25-foot vegetated zone (as required under the Trout
regulations), or the widest width that is practical under the site conditions, must be
restored 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 edge 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. 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.)
North Hills Trail Bridge
Page 5 of 6
May 22, 2006
14. If 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. Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 213. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
17. 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 or locally delegated program has released the project.

Enclosed are seven (7) copies of a Pre-construction Notification (PCN) and a $200 application
fee for the construction of a new trail bridge over the North Mills River, on the Pisgah Ranger
District of the Pisgah National Forest, in Henderson County, North Carolina. The purpose of the
project is to replace a trail bridge which was damaged by the remnants of Hurricanes Francis,
Ivan, and Jeanne which impacted the area in September 2004. This project includes construction
of new abutments, installation of a new prefabricated steel truss bridge, minor utility line
relocation, rip-rap bank protection, minor trail reconstruction, and site restoration.
Based on our review of the authorized Nationwide Permits (NWP) we believe this project is
covered under NWP 3. As required by General Condition #3404 and PCN instructions, we are
requesting Section 401 water quality certification for this project. Concurrent with this
application, the PCN has been submitted to the US Army Corps of Engineers for Section 404
permit approval

9. Describe the existing conditions on the site and general land use in the vicinity of the
project at the time of this application:
Page 2 of 10
The project bridge spans the North Mills River at the North Mills Recreation Area. The
previous bridge was severely damaged by debris in the flooding of September 2004.
Debris carried in the flood waters dislodged one of the existing bridge piers. The
recreation area sits in stands of hardwood and mixed conifer timber, with under brush of
laurel and rhododendron. The soils are clayey silts, overlying cobble rock. This trail
loop is used by thousands of visitors each year to view the unique flora in the area, (the
pink flower).
10. Overall project description in detail including the type of equipment to be used:
The new planned bridge will be a steel truss bridge with a span of 85 feet, with wood
deck and steel railings. The structure will have cast-in-place, structural concrete
abutments. There is access to both sides of the river via an road bridge. It is anticipated
that the builder will set the bridge the bridge in two pieces, even though there is the
access to both abutments for heavy equipment access. In order to protect the historical
rock retaining wall (south bank) mid stream support will most likely be employed.
Usually, the mid stream support consists of an oversized steel "sawhorse" type structure
with adjustable legs (necessary for adjustment to stream bottom). This structure is set in
the stream to support one half of the span until the second half can be placed. Excavation
will be necessary on the north side of the river in order to key the machine-placed riprap
for the north abutment. Riprap will also be placed for about 35 feet downstream from the
north abutment to repair erosion that occurred in the September 2004 high water event.
There will be no riprap placed on the south stream bank as the existing historical wall
continued to be utilized for abutment protection. The two midstream piers that support
the existing water/sewer piping will be removed. The new piping will be suspended on
hangers under the deck of the new structure. Erosion and sedimentation control will be
maintained throughout this project primarily through proper water management,
construction sequencing, proper staging and stockpiling material, and the maintenance at
all times, of suitable channel capacity for expected flow events. No equipment, fuels,
lubricants, or other potential sources of water pollution will be stored in areas that could
be flooded during this project. Work within the wetted perimeter of the stream will not
be allowed from October 15`h -April 15`h'
11. Purpose of the proposed work:
The North Mills River Trail Bridge connects the campground areas and day-use areas at
this site. The trail is used by recreationists of all types, and during the winter months
after the camping season passes, provides access by sportsmen. This bridge will be ADA
accessible providing access to the entire recreation site. Placement of the designed riprap
will prevent erosion of the abutments and the continued bank erosion. The new bridge
will afford a larger stream cross sectional area in case of future high water and will sit
approximately 4 feet higher than the old bridge.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine; delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: 1).North Abutment: Placement
of Riprap. Riprap extends approximately 12 additional feet downstream at this abutment to
repair bank erosion from 9/2004 storms. 2). Temporary mid-span support during bridge
halves placement necessary for protection of the historic CCC wall. 3). Removal of
damaged in-stream piers. Total disturbance area in acres: 0.013

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/ncwettands/sti-mgide.htm].
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.
N/A
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
website at http://h2o.enr.state.ne.us/wip/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A

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 2B .0242 or.0244, or.0260. N/A
XI. Storm water (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. N/A
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.
Contract requires portable sanitation facilities for employees.
XIII. Violations (required by DWQ)
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
http://h2o.enr.state.ne.us/ncwet]ands. 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

* Bridge replacement is associated with a designated trout stream. The trout moratorium applies
here - work will not be conducted during October 15 through April 15 (spawning period), on rainy
days, or at elevated levels of flow.
** The proposed project activities have been cleared by the Heritage Resources specialist with the
following mitigation: a qualified archaeologist or certified Heritage Resource Technician (HRT)
must monitor the proposed activities at the time of implementation. The archaeologist or HRT must
provide a report of the monitoring activity and its findings to the Forest Archaeologist or his
1
representative for inclusion in the project file. If cultural resources are discovered during the
implementation, all activities must stop and the Forest Archaeologist or his representative needs to
be contacted immediately. Any further data recovery and site mitigation will be initiated at the
direction of the Forest Archaeologist or his representative.
I have reviewed the information noted above and I recommend that this project be implemented.
