Sylva, North Carolina 28779 VVA16?
Dear Mr. Watson:
You have our approval, in accordance with the attached. conditions and those listed below, to incur the following
impacts in order to make improvements to NCSR 1509B (Crabtree Mountain Road), in Haywood County:
• 34 linear feet of new piping impacts to two (2) unnamed tributaries to Thickety Creek at Station Nos. 12+24 and
61+53;
Relocate 130 linear feet of an unnamed tributary to Thickety Creek between Stations 12+50 and 13+80.
The project must be constructed in accordance with the application dated March 25, 2004 (received March 31, 2004),
including the environmental commitments 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.
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 wastes, spoil, solids, or fill 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 N. C. Division of Land
Quality has released the project.
4. NCDOT shall comply with any conditions or moratoriums requested by the NC Wildlife Resources
Commission.
5. The stream relocation must be constructed in a dry work area and stabilized before the stream flow is diverted.
Vegetation used for bank stabilization shall be limited to native woody species and should include a vegetated
riparian buffer on both sides of the stream to the maximum extent possible.
6. If the NCDWQ determines that the stream relocation area has become unstable, NCDOT will be required to
stabilize this area. Should repairs be necessary, NCDOT must submit all repair designs to and.receive approval
from the North Carolina Division of Water Quality, before the repair work is performed.
7. The natural dimension, pattern and profile of the stream above and below the culverts should not be modified
by widening the stream channel or changing the depth of the stream.
8. Riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction.
9. Stormwater should 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.
10. Culverts that are less than 48-inch 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-inch 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, and re-installed correctly, unless demonstrated that this is
topographically unfeasible.
11. 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.
12. 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.
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 of the stream crossings and relocations 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. If concrete is used during culvert installation (e.g., headwalls), a dry work area should 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.

17. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is strictly prohibited. .
18. 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 culverts. Instream dredging has catastrophic effects on aquatic life and disturbance of
the natural form of the stream channel will likely cause downstream erosion problems, possible affecting other
land owners.
19. Rock check dams at culvert outlets should be removed at project completion to avoid blocking movement of
aquatic life.
20. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone,
except for permitted areas associated with culvert conditions.
21. All work shall be performed during low flow conditions (below bankfull).
22. 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 401/Wetlands Unit of the NC
Division of Water Quality upon completion of the project. 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 1509 - Crabtree Mountain Road
Haywood County
State Project No. 14C.044088 (DWQ Major Permit Fee $475)
Dear Mr. Lund:
The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, and
pave SR 1509, Crabtree Mountain Road, in Haywood County. This proposal entails widening
and paving the existing gravel road to a standard 18-foot roadway. The proposed improvements
of SR 1509 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 2004 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 and the channel change 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
culvert at Site 3 is perched and cannot be corrected due to bedrock, the steepness of the fill slope,
or surrounding terrain. Natural channel design techniques (pattern, dimension, and profile) will
be used when relocating the stream and the new stream banks will be stabilized with erosion
control matting and vegetation. No threatened or endangered species are known to be present in
or near the project area; therefore, no significant impacts are anticipated from project
construction. 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
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 UT to Thickety Creek
(DWQ Class C). Listed below is a summary of the proposed impacts.

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 1509 to current NCDOT standards All pipe extensions will be placed below the
existing stream bed adient so natural substrate can be re-established.
VIII. Mitigation
Page 5 of 8
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
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.:

Summary of Stream Impairment and Restoration Goals:
The existing stream section to be relocated to allow roadway widening is in a pasture and is entrenched.
The reference reach is immediately upstream of the section to be relocated. It extends into a wooded
mountain cove Above the reference reach it is steeper and has characteristics of an A" type stream.
The measured bankful dimensions were slightly less than the regional curve while the bankful flow
calculated from the Manning Equation was slightly greater than the regional curve. The design bankful
flow was targeted at slightly greater than the existing due to the possibility of development in the watershed.
The existing pipe is to be extended upstream 20 feet The channel change ends at the beginning of the
proposed pipe extension Cross vanes and fiber matting are used for stability.
