Subject Property: Green River EWP (DSR 2005-17)
DWQ Project # 05-0987
Polk County
Approval of 401 Water Quality Certification with Additional Conditions
Dear Mr. Talbert:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 150 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 June 14, 2005. After
reviewing your application, we have decided that the impacts are covered by General
Water Quality Certification Number(s) 3367 (3367). 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, but not the design, that you described in III. 10. of your
application. (Nothing in this approval should be interpreted as giving permission
to remove bedload material form the existing channel, nor allowing for the
construction of berms which would not allow the stream access to it's
floodplain.) 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:

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 150 feet Green 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.
e

June 20, 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. 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
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.
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 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. Disturbed stream banks and a 25-foot vegetated zone, 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
Polk County:
Page 5 of 6
June 20, 2005
(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.
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. 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.)
17. 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 at http://h2o.enr.state.nc.us/ncwetlands. The text of
the sample deed notification may be modified as appropriate to suit to this
project.
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.
19. 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.

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
The proposed site consists of light residential uses. The stream and stream banks were
heavily impacted during Tropical Stones Frances and Ivan. Extensive stream bank erosion
threatens the stability of existing structures.
9. Describe the overall project in detail, including the type of equipment to be used:
EWP 2005-17
This project area includes approximately 150 linear feet of Green River bank. The project
area is located at 35°18'39"N 82°3.0' 18"W. High-water flows have resulted in erosion and
caused damage to the adjoining pasture. Attachment 1 contains representative photos of the
project area.
Repairs in this reach of stream will involve the following:
- Stabilize the channel in its pre-flood configuration using organic structures
- Remove woody debris from the channel and adjoining floodplain
- Reseed and plant woody vegetation
The techniques that will be utilized for the proposed repairs at the EWP site listed
above are described below.
Streambank Repair
When possible, excavation equipment will access streambank repair areas from the dry and
will not track into the stream channel. Most of the steep eroded streambanks are opposite or
adjacent to the debris removal areas. At these areas, the rocky material removed from the
floodplain will be used to stabilize the stream bank, with the addition of large boulders along
the toe of the slope as necessary to stabilize and protect the toe. Where suitable material is
available, rock vane and root wads will be installed in the restored bank section to reduce
bank stress and provide stability to the unconsolidated fill (typical structure cross-sections
and plan views are included in Exhibit 3).
An existing cross section and site specific design components are included in Attachment I
for each of the impacted channel sections requiring stabilization. Drainage areas of project
areas are also included in those attachments. The drainage area is used to determine the
design storm peak flow using USGS Rural Regression equations for the Blue Ridge-
Piedmont. Design storm velocity and shear stress values were also calculated. This
information, in conjunction with the field investigation analysis, DSR notations, and agency
guidance and regulations, are used to develop an appropriate streambank stabilization design.
Additional information on general design features, erosion control practices and debris
removal practices is included in Attachment 2.
Page 3 of 10
Equipment that may be used to accomplish the above listed tasks includes; rubber tired
skidders, 15 ton dump truck, hydraulic track mounted excavator with thumb, and chainsaws.
10. Explain the purpose of the proposed work:
The work addressed in this application is intended to improve post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are
threatening structures or other property. The proposed actions are not intended to enhance
existing conditions or restore 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.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date pen-nits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.

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. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must 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

local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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.
When at all possible equipment will be kept out of the stream channel, stream crossings will be
minimized, and no excavation will be below the existing channel bed. When at all possible
stream material will be moved from dry areas to banks, minimizing the movement of wet (or
below water line) stream material. Creating wide, shallow channels will be avoided. Temporary
and/or permanent herbaceous vegetation shall be planted on all bare soil within 15 days of
ground disturbing activities. Rocky material shall not be used for bank stabilization above the
normal high water mark. Large rocky material will be brought in to stabilize the toe of impacted
streambanks where necessary.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors

Definition Small temporary stone dams constructed across a drainageway.
Purpose To reduce erosion in a drainage channel by restricting the velocity of flow in
the channel.
Conditions Where Thispractice may beused as a temporary or emergency measure to liMiEerosion
Practice Applies by reducing flow in small open channels. Limit drainage areas to 2 acres or less.
Do not use check dams in live streams.
Check dams may be used to:
• reduce flow in small temporary channels that are degrading, but, where
permanent stabilization is impractical due to their short period of useful-
ness;
• reduce flow in small eroding channels where construction delays or
weather conditions prevent timely installation of nonerosive liners.
Planning Check dams are an expedient way to reduce gullying in the bottom of channels
Considerations that wilt be filled or stabilized at a later date. It is usually better to line the chan-
nel or divert the flow to stabilize the channel than to install check dams.
However, under circumstances where this is not feasible, check dams may be
helpful. .
Design Criteria
Check dams installed in grass-lined channels may kill the vegetative lining if
submergence after rains is too long and/or silting is excessive. All stone and
riprap mustbe removed if mowing is planned as part of vegetative maintenance.
Consider the alternative of protecting the channel bottom with materials such.
as riprap, concrete, fiberglass mat, or other protective linings in combination
with grass before selecting check dams.
The following criteria should be used when designing a check dam:
• Ensure that the drainage area above the check dam does not exceed 2
acres.
• Keep the maximum height at 2 ft at the center of the dam.
• Keep the center of the check. dam at least 9• inches lower than the outer
edges at natural ground elevation.
• Keep the side slopes of the dam at 2:1 or flatter.
• Ensure that the maximum spacing between dams places the toe of the
upstream dam at the same elevation as the top of the downstream dam
(Figure 6.83a).
• Stabilize overflow areas along the channel to resist erosion caused by
check dams.
6.83.1
Figure 6.63a Space check dams in a channel so that the crest of downstream dam Is at elevation of the too of upstream dam.
• Use 4 to 15-inch stone (N.C. Department of Transportation class 1 or class
B erosion control stone).
• Key the stone into the ditch banks and extend it beyond the abutments a
minimum of 18 inches to avoid washouts from overflow around the dam.
-- - - - - Construction-1: Place-stone-to-the•lines-and-dimensions-shown iwthe plan on a filter fabric-'-- --------
SPeCItICatIOnS. foundation.
2. Keep the center stone section at least 9'inches below natural ground level
where the dam abuts the channel banks.
3. Extend stone at least 1.5 ft beyond the ditch banks (Figure 6.83b) to keep
overflow water from undercutting the dam as it re-enters the channel.
4. Set spacing between dams to assure that the elevation at the top of the lower
dam is the same as the too elevation of the tipper dam.
5. Protect the channel downstream from the lowest check dam, considering that
water will flow over and around the dam (Practice 6.41, Outlet Stabilization
Structure).
6. Make sure that the channel reach above the most upstream dam is stable.
7. Ensure that channel appurtenances, such as culvert entrances below check
dams, aro not subject to damage or blockage from displaced stones.
Maintenance Inspect check dams and channels for damage after each runoff event.
Anticipate submergence and deposition above the check dam and erosion from
high flows around the edges of the dam. Correct all damage immediately. If
significant erosion occurs between dams, install a protective riprap liner in that
portion of the channel (Practice 6.3 1, Riprap-lined and Paved Channels).
Remove sediment accumulated behind the dams as needed to prevent damage
to channel vegetation, allow the channel to drain through the stone check dam,
and prevent large flows from carrying sediment over the dam. Add stones to
dams as needed to maintain design height and cross section.

Organic Debris Removal
Standard Operation Procedures (SOP)
Emergency Watershed Protection (EWP) Stream Repair Projects
McDowell County, North Carolina
SCOPE OF WORK
The work shall consist of the cleanup of designated stream areas by the removal and
disposal of trees, logs, stumps, brush, tops, rubbish, and other debris deposited in the
stream channel and floodplain by the storms of September 8 and 16, 2004.
CLEARING AND DEBRIS REMOVAL
Debris removal crews shall remove only that material which has been clearly marked by a
representative of McDowell County and/or CH2M HILL, INC (Representative) as indicated
by flagging and/or orange/red spray paint. ONLY marked debris is to be removed.
Representative cannot authorize additional work. Any work that will result in an increase in
cost must be submitted to CH2M HILL for approval prior to starting such work. In the event
that the contractor uses on-site chipping, the chipper may follow the clean-up crew along the
length of the project reach. The Contractor is responsible to properly dispose of clops.
Proper disposal may include spreading on site or removing off-site. On-site disposal requires
written approval by the property owner. Unless specifically requested to leave the chips in a
pile by a property owner the chipper shall make reasonable efforts to spread the chips as
chipping progresses.
Chippers and other heavy equipment will be staged and used at least 30-feet from the top of
the streambank or on existing paved or graveled areas prepared in accordance with standard
details described in Figure 18 (Attachment 1).
Repair of any property damage resulting from debris removal is the sole responsibility of the
Contractor.
All debris removal shall be within the included sites as identified in this solicitation and as
directed by the Representative. For bid preparation purposes, the Representative has
marked and identified debris to be removed. Removed debris shall be placed only in
those areas as directed by the Representative. For Bid purposes, debris staging areas are
assumed to be within 300 feet of top of bank. On-site burning is not allowed. Fallen
trees, limbs and dislodged brush within the cross section of the existing or original
channel up to and including the debris line of the subject storm shall be removed. Any
foreign (man-made) debris washed in from upstream, shall be removed. Marked trees
severely undercut by stream bank erosion and trees severely leaning over the channel
whose near term fall is apparent shall be removed.
In general, Contractor clearing will be limited to the cutting of severely damaged trees
leaning across the channel, and other trees as needed to gain access for equipment to points
of channel blockage.
P:\PolkCountyNorthCarol\327550\Permits\PCN's_Polk_Complete\Polk_FinaIPCN_DSR_17\Attcll_2\Debris Removal
SOP_final.doc 1
Disturbance of the channel bottom and banks, and equipment access areas shall be held
to the minimum necessary to allow the construction equipment to remove the debris and
shall be consistent with all state and federal permits. All areas disturbed due to debris
removal or equipment access shall be reshaped and reseeded in accordance with
standard details described in Figures 7-18 (Attachment 1).
Access to the channel will generally be perpendicular to the channel so cutting of trees is
held to a minimum with precaution taken to protect mast producing and stream canopy
trees. Un-marked dead trees that provide den habitat and are determined to pose no
hazard to the channel shall be protected. As such, the contractor will only remove marked
debris. The contractor will exercise care in the areas of existing crops to minimize
damages.
PROVIDED EOUIPMENT & FACILITIES
The Contractor shall provide adequate sanitary facilities for equipment operators and
work crews. Portable facilities shall be provided at the worksite and arrangements made
for proper servicing. A portable facility will be provided within 1,000 feet of the
equipment and/or work crews at all times.
COMMUNICATIONS
Each mechanized piece of equipment and each work crew shall be equipped with a two
way, battery operated radio. Radios shall be FM, have a minimum range of 5 miles.
Radios shall be maintained "on" and in the receive mode at all times while the operator is
at the site. Batteries shall be recharged overnight or as needed. An extra set of fully
charged batteries shall be maintained on board the equipment at all times. Radios shall
be equipped with clip-on hand mikes or headsets. Radios shall be maintained in good
operating condition and equipment operators shall be knowledgeable in the use and care
of the radios. Each Contractor site supervisor shall also maintain a secondary
communication system compatible with the Representative's system.
Brush Removal Guidelines
• Small diameter brush and limbs (less than four inches in diameter) that will not
cause damage if remobilized by high water will be cut into short lengths (five feet
long or less) and left in place.
• All marked, dislodged or uprooted larger diameter brush will be removed from
the channel or streambank and chipped in designated areas greater than 30-feet
from the top of the bank.
• Saplings and shrubs with an intact root system are not to be removed.
P:\PolkCountyNorthCarol\327550\Pemlits\PCN's_Polk_Complete\Polk_FinaIPCN_DSR_17\Attch_2\Debris Removal
SOP_final.doc 2
Tree Removal Guidelines
• Trees will be chipped in designated areas greater than 30-feet from the top of the
streambank. Chippers and/or tub grinders may be staged on-site with written
consent from the property owner or at a central location approved by the County.
• Larger diameter trees may be pulled to the chipper using a mechanized winch
provided the process does not create excess disturbance to the streambank.
• Marked trees whose near term fall is apparent should be cut at the marked
location, which will be indicated by a painted ring around the trunk at least three-
feet above the ground surface. The root system shall not be removed from the
streambank.
• As approved by the Representative, larger diameter trees that cannot be moved
using hand equipment will be cut to manageable lengths and removed.
• The sale of chips or firewood is not allowed.
Foreign Debris and Trash Removal Guidelines
• Foreign (manmade) debris and trash will be bagged in orange trash bags where
possible.
• Filled trash bags will be removed from the channel and transported directly
offsite by the Contractor to the local landfill.
• Large debris must be loaded into a dump truck or roll-off container and
transported to the local landfill for disposal.
• Local landfill is located at McDowell County Landfill. Tipping fees are $ 32/ ton,
which shall be paid by the Contractor.
Stream bed and Bank Repair Guidelines
• All temporary stream crossings shall be installed as described in Figures 15 -18
(Attachment 1).
• All Stream embankments disturbed by Contractor activities, denuded, or left bare
as a result of debris removal shall be regraded, planted, and erosion control fabric
installed as described in Figures 6, 7, and 9 -12 (Attachment 1).
• Temporary staging, chipping, and work access points shall be regraded and
grassed using a native grass/herb mix as outlined in Figures 6, 7, and 16 -18
(Attachment 1).
P:\PolkCountyNorthCarol\327550\Permits\PCN's_Polk_Complete\Polk_FinaIPCN_DSR_I7\Attch_2\Debris Removal
SOP_final.doe 3
• Contractor shall install erosion control measures as outlined in Figures 10 -18.
SUPERINTENDENCE OF EQUIPMENT AND WORK CREWS
Any contractor providing three (3) or more pieces of equipment or five (5) or more work
crew or equipment operators shall provide a non-working crew superintendent in
addition to the required laborers and operators. The contractor shall designate in writing
the names of the crew superintendent and an alternate prior to award of the contract. The
crew superintendent shall provide on-site supervision of work crews and equipment
operators. The crew superintendent shall be responsible for the safety of work crews and
for the location and servicing of portable sanitary facilities. He/she shall be equipped
with a portable communication as specified above.
The crew superintendent shall communicate with the Representative to assure that work
crews and equipment are performing at a satisfactory level. The crew Superintendent
shall coordinate with the Representative to schedule equipment and operators for each
days work and as far in advance as possible. The superintendent shall be responsible for
keeping up with the daily operating times of all work crews and equipment and shall
maintain a log of daily equipment and work crew operations. He/she shall coordinate
daily with the Representative to concur on actual footage of streambank cleared.
WORK DIRECTION
Contractors and equipment operators will not perform activities requested or instructed
by landowners or others at the worksite, except as confirmed by the assigned
Representative.
ENVIRONMENTAL CONSIDERATIONS
Earth moving equipment will cross and operate in the stream flow only when necessary
and only when directed to do so by the Representative. Equipment shall be maintained
to prevent fuel, oil and lubricant spills in the vicinity of the stream. Refueling, repairs
and lubrication will be performed at safe distances from the stream and only at locations
approved by the Representative.
Should fuel leaks, oil leakages or hydraulic pipe rupture occur during construction, the
operators will immediately remove the equipment to a "safe" area and proceed with
repairs. The Representative will direct operators to remove equipment from the stream
whenever a leak is observed or suspected.
P:\PolkCountyNorthCarol\327550\Pemiits\PCN's_Polk_Complete\Polk_Fina]PCN_DSR_17\Attch_2\Debris Rcmoval
SOP_final.doc 4
SAFETY
Contractor shall be responsible for the safe execution of this work and conform to all
applicable state and federal regulations. Additionally, at work sites, where equipment
will be operating on public roads, flagmen shall be stationed to warn oncoming traffic of
congestion, construction road signs shall be in place and a means of removing sediment,
mud or rocks from roadways shall be established. Residue deposited on roadways may
be removed by sweep machine, manual sweeping methods or pressurized water. The
contractor will be responsible for the implementation of these measures.
Chain saw operators will be expected to perform debris removal operations during
periods of extreme weather conditions and in areas of deep and fast moving water. The
contractor is responsible for providing the necessary equipment, clothing and other gear
to insure that laborers can perform effectively and safely under these conditions. The
Contractor shall determine if working conditions are hazardous and/or of sufficient
extreme to prevent efficient and effective operation. When such conditions exist, the
Contractor shall shut down work crews until conditions improve.

`A11: Attached is an electronic copy of the letter and information sheet
sent to the 19 counties and one town that have contracts with NRCS for
stream clearing projects. Those letters went out over the Secretary's
signature on Friday. We will hand-deliver a memo containing the same
basic information to the mountain area legislators tomorrow. We are
also working with the Governor's office on a news release; I am not sure
how soon that will go out. Give me a call if you have any questions.
Thanks for working toward getting meetings set up. Robin.

RE: Emergency Watershed Protection Stream-Clearing Projects
Dear
I know that County experienced stream damage as a result of the fall
hurricanes. Our department would like to work closely with your county to insure that
stream restoration projects receiving state and federal funds under the Emergency
Watershed Protection (EWP) program move as smoothly as possible through the
environmental review and permitting process. I have enclosed for your information a
brief summary of the types of permits and approvals that may be required for these
projects. For projects that involve work directly affecting the streambed, the United
States Army Corps of Engineers will be the primary environmental permitting agency.
For those projects, our staff in the Division of Water Quality and the Division of Land
Resources play a supporting role and issue related state approvals.
I have asked our staff to meet with all of the western counties, either individually or in
small groups, to talk about each county's proposed stream restoration projects and answer
your questions about permit requirements. Our staff will ask the Corps of Engineers and
Soil and Water Conservation staff to join in those meetings in an effort to put together a
plan of action for reviewing and approving stream restoration projects as quickly as
possible. You should receive a telephone call from DENR staff soon to talk about a date
and time that would be convenient to meet and talk about your projects.
I have also directed our staff to waive fees for state water quality certifications (under
Section 401 of the Clean Water Act) and for approval of erosion and sedimentation
February 25, 2005

control plans for stream-clearing projects funded under EWP. Fees will be waived for all
EWP permit s requested by September 1, 2005.
I hope these efforts will ease the burden on county governments already challenged by
the demands of reconstruction and recovery. If we can help you in any other way, please
do not hesitate to call. I have asked Assistant Secretary Robin Smith to be a. primary
contact on these projects for DENR; you can reach Ms. Smith at (919) 715-4141. The
enclosed information sheet also provides contact information for DENR staff in both the
Asheville and Winston-Salem Regional Offices and for the Corps of Engineers office in
Asheville.
Sincerely,
William G. Ross, Jr.
