APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. J. B. Setzer, P.E.
Division Engineer
N C Department of Transportation
253 Webster Road
Sylva, North Carolina 28779
Dear Mr. Setzer:
You have our approval, in accordance with the attached conditions and those listed below, to impact 29 linear feet of two
(2) unnamed tributaries to Big Creek (29 linear feet of new culvert), in order to make improvements to NCSR 1332
(Waterville Road) in Haywood County. The project should be constructed in accordance with your application dated
April 20, 2005 (received April 27, 2005), including the environmental comments made in the application letter. After
reviewing your application, we have decided that this fill is covered by General Water Quality Certification No. 3404,
corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you must acquire any
other federal, state or local permits before you proceed with your project including (but not limited to) Sediment and
Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval will expire with the
accompanying 404 Permit unless otherwise specified in the Water Quality Certification.
This approval is valid solely for the purpose and design described in your application (unless modified below). Should
your project change, you must notify the DWQ in writing and submit 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 the
conditions. If total wetland fills for this project (now or in the future) exceed one acre, or if total impacts to streams (now
or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any
additional conditions listed below.
1. 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. Any reclamation measures and implementation must comply with the reclamation in accordance with the
requirements of the Sedimentation Pollution Control Act.
2. No waste, spoil, solids, or till of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the
impacts depicted in the Preconstruction Notice Application. 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.
3. 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 Quality has released the project.
4. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the trout-spawning
season of January 1 through April 15, to protect the egg and fry stages of trout from off-site sedimentation during
construction of the roadway.
5. The NCDOT shall use Best Management Practices for the Protection of Surface Waters (NCDOT August 2003) and
Sedimentation and Erosion Control Guidelines for Sensitive Watersheds [15A NCAC 4B .0124 (a)-(e)]. Temporary
or permanent herbaceous vegetation should be planted on all bare soil within 5 days of ground disturbing activities to
provide long-term erosion control. Erosion control mating 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 or wherever possible,
live stakes of native trees.
6. Culverts that are less than 48-inches in diameter should be buried to a depth equal to or greater than 20% of their size
to allow for aquatic life passage. Culverts that are 48-inches in diameter or larger should be buried at least 12 inches
below the stream bottom to allow natural stream bottom material to become established in the culvert following
installation and to provide aquatic life passage during periods of low flow. This may require increasing the size of the
culvert to meet flow conveyance requirements. If any of the existing pipes are perched, they shall be removed and
replaced, or re-installed correctly, unless demonstrated that this is topographically unfeasible.
7. The dimension, pattern and profile of the stream, above and below this work, should not be modified by widening the
stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural
geomorphic conditions.
8. Stormwater shall be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for
the purpose of pre-treating stormwater runoff, and must not be routed directly into streams. Mowing of existing
vegetated buffers is strongly discouraged, so that they may be utilized for stormwater diffuse flow.
9. Removal of vegetation at the stream crossing and adjacent to streams should be minimized. Native trees and shrubs
(e.g. Rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be
planted along the streambank to reestablish the riparian zone and to provide long-term erosion control in the vicinity
of the road crossing and along the streams within dedicated rights of way.
10. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and
vegetation should be used for stabilization above the high water elevation. Riprap should not be place in stream
channels in such a manner that it impedes aquatic life passage. Any rocks placed on the bank should be backed with
filter cloth and should be clean and sediment free.
11. Rock check dams at culvert outlets should be removed at project completion to avoid impeding the movement of
aquatic life.
12. If concrete is used during culvert installation (e.g., headwalls), a dry work area must be maintained to prevent direct
contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be
discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
13. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize
sedimentation and to reduce the likelihood of introducing other pollutants into the stream.
14. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
15. Excavation in the stream channel should be conducted in the dry, if possible. Sandbags, cofferdams, flexible pipe or
other diversion structures should be used to minimize excavation in flowing water.
16. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is
strictly prohibited.
Mr. J. B. Setzer, P.E.

17. The presence of equipment in the channels must be minimized. Under no circumstances must rock, sand or other
materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate
vicinity of the bank stabilization work. fn-stream dredging has catastrophic effects on aquatic life, and disturbance of
the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting other
landowners.
18. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for
permitted areas associated with the bank stabilization work.
19. All work shall be performed during low flow conditions (below bankfull).
20. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion " form
to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall
complete the attached form and return it to the Transportation Permitting Unit of the NC Division of Water Quality
upon completion of the project. The NCDOT is strongly advised to send in photographs upstream and downstream of
each structure to document correct installation.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.

Subject: Nationwide 14 Permit Application
SR 1332 - Waterville Road
Haywood County
State Project No. 14C.044072 (DWQ Minor Permit Fee $200)
Dear Ms. Pennock:
The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, and
pave SR 1332, Waterville Road, in Haywood County from the end of pavement for a distance of
2.64 miles. This proposal entails widening and paving the existing gravel road to a standard 18-
foot roadway. The proposed improvements of SR 1332 have been identified as necessary
maintenance and safety improvements. Funds have been allocated for this project, and NCDOT
would like to perform these activities sometime during the 2005-06 paving season.
I am sending a straight-line diagram with the proposed erosion control and construction-limits
along this project. In addition, I am sending a typical section of the road, cross sections,
drawings for pipe culvert replacements as well as a marked county map and USGS quad map.
We propose to install the new culverts slightly below the existing streambed elevations where
bedrock is not encountered to minimize impacts to aquatic habitats and allow the existing stream
gradients to remain as unchanged as physically possible.
The North Carolina Natural Heritage Database was checked for records of threatened and
endangered species. There were no records of threatened and endangered species listed for the
unnamed tributaries of Big Creek. Additionally, there are no records of threatened and
endangered species for the entire Big Creek watershed. The unnamed tributaries are small (2-3
feet in width). The impacts from two pipe replacements will be minimal. For these reasons,
there will be "no effect" on threatened or endangered species.
`?
Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation
Office (SHPO) and the Office of State Archaeology determines that further investigations are
required, NCDOT will conduct the appropriate site investigations and obtain compliance from
SHPO prior to project construction.
The best management practices will be used to minimize and control sedimentation and erosion
on this project. The construction foreman will review all erosion control measures daily to
ensure sedimentation and erosion is being effectively controlled. If the planned devices are not
functioning as intended, they will be immediately replaced with better devices. The rock silt
screens and other erosion control devices will be in place prior to pipe culvert construction and
will remain in place until the project is stabilized.
Impacts to Waters of the United States
The unnamed tributaries of Big Creek are 2-3 feet wide and have perennial flow: The channel
substrate is composed primarily of boulders and cobble. The substrate of one channel at the inlet
is bedrock. The channels lack vegetation. For these reasons, we believe that these streams are
under the jurisdiction of the U. S. Army Corps of Engineers. In order to construct the project in
accordance with our current secondary road standards, it will be necessary to impact waters of
the United States in the French Broad River Basin. Specifically, NCDOT is requesting to
extend/replace two metal culverts in unnamed tributaries to Big Creek (DWQ Class C Tr HQW).
Listed below is a summary of the proposed impacts.

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.
Impacts cannot be avoided Culverts must be extended in order to gain the necessary width
to improve SR 1332 to current NCDOT standards All pipe extensions will be placed below the
existing stream bed gradient so natural substrate can be re-established.
VIR Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 5 of 9
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 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
htt_o flh2oenr.state_ncus/ncwetlands/strm<,ide.html.
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.
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
(919) 715-0476 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the

XI. Stormwater (required by DWQ)
Describe impervious acreage (both 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.
Stormwater will be diverted throw hg settling, basins or grass lined buffers prior to entering
streams See erosion control plan)
X11. 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.
No wastewater will be generated from the proposed project
XIll. 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. 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
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

Erosion Control Schedule
• Install erosion control measures according to plans in all outlets and at other
discharge points after clearing but before grubbing
• Clear and clean outfall ditches leaving side slopes at an angle that can be retained by
vegetation. These areas will require stage seeding and mulching.
• Begin grading of roadway ditches. Place erosion control measures along roadway
ditches as grading progresses and conditions allow.
• Seed and mulch all disturbed areas as soon as any phase of grading is completed.
(Note there are 15 working days/30 calendar days to complete seeding and mulching.
A working day is defined as a day exclusive of Saturday or Sunday during which
weather conditions or soil conditions permit land-disturbing activity.)
• Clean out and/or rework all temporary erosion control measures after any significant
rainfall event (or as otherwise needed). These measures should be maintained until a
permanent vegetative cover is established.
Wet Pipe Installation Schedule
• Install erosion control devices.
• Remove material and existing pipe while limiting, as much as possible, material and
sediment from entering the stream and/or escaping from the project.
• Prepare pipe foundation while taking care to limit material and sediment from
entering the stream and/or escaping from the project. Where possible new grade
should be below the existing streambed. If needed, bedding material will be clean
stone (especially in Trout and HQW waters).
• Place new pipe and compact fill.
• Install slope protection on outlet and inlet ends of pipe. Also complete installation of
erosion control measures and perform maintenance as needed on existing measures.
• Establish permanent vegetation as soon as possible.
Environmentally Sensitive Areas:
This project is located in an "Environmentally Sensitive Area". This designation requires
special procedures to be used for clearing and grubbing, temporary stream crossings, and
grading operations within the area identified on the plans. This also requires special
procedures to be used for seeding and mulching and staged seeding within the project.
Clearing and Grubbing:
In areas identified on the erosion control plans as "Environmentally Sensitive Areas",
clearing operations can be performed, but not grubbing operations until immediately prior
to beginning grading operations as described in Section 200, Article 200-1, in the
Standard Specifications. The "Environmentally Sensitive Area" shall be defined as a 50
foot buffer zone on both sides of the stream (or depression), measured from top of
streambank, (or center of depression). Only clearing operations (not grubbing) shall be
allowed in this buffer zone until immediately prior to beginning grading operations.
Erosion control devices shall be installed immediately following the clearing operation.
Grading:
Once grading operations begin in identified "Environmentally Sensitive Areas", work
will progress in a continuous manner until complete. All construction within these areas
must progress in a continuous manner such that each phase is complete and areas
permanently stabilized prior to beginning of next phase. Failure to complete any phase of
construction in a continuous manner in "Environmentally Sensitive Areas" as specified
will be just cause for the Engineer to direct the suspension of work in accordance with
Section 108-7 of the Standard Specifications.
Temporary Stream Crossings:
Any crossing of streams within the limits of this project must be accomplished in
accordance with Section 107-13(b) of the Standard Specifications.
Seeding and Mulching:
Seeding and mulching shall be performed in accordance with Section 1660 of the
Standard Specifications and vegetative cover sufficient to restrain erosion shall be
installed immediately following grade establishment.
Seeding and mulching shall be performed on the areas disturbed by construction
immediately following final grade establishment. No appreciable time shall lapse into the
contract time without stabilization of slopes, ditches and other areas within the
"Environmentally Sensitive Areas" as indicated on the E.C. Plans.
Stage Seeding:
The work covered by this section shall consist of the establishment of a vegetative cover
on cut and fill slopes as grading progresses. Seeding and mulching shall be done in
stages on cut and fill slopes which are greater than 20 feet in height or greater than 2 acres
in area. Each stage shall not exceed the limits stated above.
