Approval of 401 Water Quality Certification with Additional Condi'"iot10?DSTORM,NATER6RANCN
Dear Mr. Creighton:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 235 linear 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 12, 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
(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. 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 which 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 Approved (Units) Plan Location or Reference
Stream 235 (feet) Gouges Branch
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.
Buncombe County:
Page 3 of G
August 22, 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, rock bars, 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
Buncombe County:
Page 4 of 6
August 22, 2005
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.
C.
df )
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.
13.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.
14. 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.
Buncombe County:
Page 5 of 6
August 22, 2005
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.
16. 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 1508 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.

EWP 2005-18
This project area consists of approximately 75 linear feet of Gouges Branch. The project
area is located at 35.627361°N 82.680889°W. High-water flows have threatened private
property. Attachment 1 contains representative photos of the eroded area.
Repairs in this reach of stream will involve the following:
-Stabilize the channel in its pre-flood configuration using organic and rock structures
-Reseed and plant woody vegetation

Repairs in this reach of stream will involve the following:
-Debris Removal
-Stabilize the channel in its pre-flood configuration using organic and rock structures
-Reseed and plant woody vegetation
The techniques that will be utilized for the proposed repairs at the EWP site listed
above are described below.
Removal of Organic Debris
Fallen trees, limbs, and non-native material within the cross section of the existing or original
channel up to and including the debris line shall be removed. Any foreign debris (e.g. trash
appliances) will also be removed. Trees leaning over the channel whose near term fall is
apparent will be removed. These rooted trees will be cut three feet above the ground surface
and the root masses will be left in place. Disturbance of channel bottom and banks and
equipment access shall be held to the minimum necessary to allow the construction
equipment to remove the debris. All areas disturbed due to debris removal and equipment
access shall be reshaped and reseeded. Access to the channel will be perpendicular to the
channel so that cutting of trees is held to a minimum with precaution taken to protect mast
production and stream canopy trees. These trees will be cut off at ground level so re-
sprouting may occur after construction. Dead trees and small brush piles that provide den
habitat and are determined to pose no hazard to the channel will be protected. Woody debris
will be chipped and disposed of in upland areas or hauled offsite.
Page 3 of 10
Streambank Repair
When possible, excavation equipment will access strcambank 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.
An existing cross section and site specific design components are included in Attachments 1
and 2 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 stornl velocity and shear stress values were also calculated. This
information, in conjunction with the field investigation analysis, DSR notations, and agency
guidance and regulations, arc used to develop an appropriate strcambank stabilization design.
Additional information on general design features, erosion control practices and debris
removal practices is included in Attachment 3.
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 arc
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 permits 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. 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
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 NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration

General Notes
The Contractor shall make his own determination of the
existing subsurface conditions. In areas where proposed
construction may conflict with existing utilities, the Contractor
shall take all necessary precautions to avoid damage to the
utilities. Notify and locate all impacted utilities at least 48
hours prior to excavation. Any damage sustained to utilities
shall be repaired by or under the direction of the utility owner
at the Contractor's expense.
All existing facilities, including but not limited to sidewalks,
roads, lawns, landscape vegetation, etc., inside and outside of
construction limits that are disturbed under this contract shall
be reestablished and/or reconstructed to the original condition
at the Contractor's expense.
Construction Sequence
1. Begin work at the upstream end of the project reach.
2. Construct proposed structures according to the plans and
specifications.
3. Grade stream banks to proposed grade, and tie into
existing banks upstream and downstream.
4. Overbank areas (beyond top of bank) adjacent to the
project reach shall be graded for positive drainage toward
the stream.
5. Apply temporary stabilization to the disturbed areas at the
end of each work day.
6. Repeat steps 1 through 5 for each segment of the project
reach, working downstream.
Site Stabilization
1. Conduct soil test to confirm necessary lime and fertilizer
amendments. Appropriate lime and fertilizer shall be
applied prior to seeding and incorporated to a depth 3 to 5
inches below the surface.
2. Temporary stabilization will be applied to all disturbed
areas on a daily basis. Areas shall be seeded with rye
grass at a rate of 15 lbs./ac. and long straw or hay
mulched. Straw shall consist of thoroughly threshed wheat,
rye or oat straw, reasonably bright in color, and shall not
be musty, moldy, caked, decayed, or excessively dusty
and shall be free of noxious weed seeds.
3. Permanent soil stabilization shall be completed within 7
calendar days of initial soil disturbance or re-disturbance.
Planting and seeding shall be incorporated into the subsoil
at the rates prescribed on Figures 6, 7, and 8. Contractor
shall follow NCDWQ Guidelines for Riparian Restoration,
http://h2o.enr.state.nc.us/wrp/pdf/buffers.pdf
4. All earth fill in excess of 1 ft depth should be installed in
lifts of maximum 6-inches and mechanically compacted.
5. All rock used for bank stabilization and in-stream structures
shall be 3 ft to 4 ft angular rock.
6. Erosion Control (EC) Fabric shall be woven coir mat,
secured with dead stout stakes, and shall meet the
following standards:
50% open area (maximum)
0.5 inch maximum opening size
4.5 lbs. per sq. foot maximum sheer stress
10 fps minimum velocity
CLT/GENERAL NOTES_NF.DOC
USE OR DISCLOSURE OF DATA CONTAINED ON THIS SHEET IS SUBJECT TO
THE RESTRICTION ON THE TITLE PAGE OF THIS PROPOSAL.
7. Filter fabric shall be Amoco Propex 2002 woven geotextile
or equivalent. Cut excess filter fabric so no fabric is visible
after installation.
8. Seeded areas not specified for coir fabric, shall be
mulched with long straw or hay mulch immediately after
seeding areas at a rate of 2 tons/acre (uniform loose depth
of 1" to 2"). Straw shall consist of thoroughly threshed
wheat, rye or oat straw, reasonably bright in color, and
shall not be musty, moldy, caked, decayed, or excessively
dusty and shall be free of noxious weed seeds. Mulch
shall be secured with biodegradable netting (Robex Super
Flow or Equal).
9. The Contractor shall be responsible for maintaining seeded
areas until 95% vegetative cover is established. Should
any seeded area fail to germinate, or washing of any areas
occur requiring re-establishment of seeding, the Contractor
shall replace any lost soil material and re-seed and
re-mulch such areas at Contractor's expense.
Standard Erosion and Sediment Control Notes
1. The Contractor shall protect all points of construction
ingress and egress by installing a temporary construction
entrance as shown in details to prevent the deposition of
materials onto public roads. All materials deposited onto
public roads shall be removed immediately.
2. The Contractor shall re-vegetate or restore access roads
(including construction entrance) to match pre-construction
conditions.
3. The Contractor shall inspect daily and maintain
continuously in an effective operating condition all erosion
and sediment control measures until such times as they
are removed with prior permission from Engineer or
agency inspector.
4. The Contractor shall protect trees and landscaping not
marked for disposal from damage. Any damage that
occurs shall be repaired at the Contractor's expense.
5. Fencing shall be maintained for animal containment. The
Contractor shall provide temporary fencing to allow for
execution of the work. The Contractor shall keep
construction equipment away from livestock and take all
precautions to prevent injury to animals.

Organic Debris Removal
Standard Operation Procedures (SOP)
Emergency Watershed Protection (EWP) Stream Repair Projects
Buncombe 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 clopping, the chipper may follow the clean-up crew along the
length of the project reach. The Contractor is responsible to properly dispose of chips.
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
clopping 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.
Repair of any property damage resulting from debris removal is the sole responsibility of the
Contractor.
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.
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.
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.
THE CONTRACTOR WILL BEAR SOLE RESPONSIBILITY FOR SELECTING THE
METHOD OF DEBRIS DISPOSAL AND THE PROPER DISPOSAL OF THE DEBRIS.
Regardless of the disposal method selected, the contractor is expected to have or obtain
knowledge of ALL aspects of the selected disposal method including, but not limited to,
associated costs and equipment, and local, State and Federal regulations. The contractor
shall obtain ANY and ALL permits for the selected disposal method and bear the cost
for the permits. Debris disposal cost shall be included in the Bidders bid. No increase in
cost will be permitted should the contractor elect to change method of disposal after the
bid is submitted. Bidders are advised that special equipment may be required for off-
site burning of debris, including, but not necessarily limited to an air curtain burner.
PROVIDED EQUIPMENT & 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.
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.
• Tipping fees for disposal shall be paid by the Contractor.
• Any structural debris to be removed must be separated in the following manner
for disposal: a) clean metal (e.g. mobile home frames); appliances (e.g.
washer/dryer, a/c, water heater, etc.); and household debris. Clean metal which
is deemed 'recyclable' will have no associated tipping fees.
Stream Bed and Bank Repair Guidelines
0 All temporary stream crossings shall be installed as described in Figures 15 -18.
• 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.
• 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.
• Contractor shall install erosion control measures as outlined in Figures 10 -18.
SUPERINTENDENCE OF EOUIPMENT 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.
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.
EQUIPMENT
Equipment selection to complete the work is the Contractor's responsibility
