DWQ Project No. 020814
SR 1251 (Chestnut Park Road)
APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. C. R. Styles, P.E., District Engineer
NCDOT
P.O. Drawer 250
Bryson City, NC 28713
Dear Mr. Styles:
You have our approval, in accordance with the attached conditions and those listed below, to impact 25
linear feet of an unnamed tributary to Richland Creek in order to improve SR 1251 (Chestnut Park Road)
in Haywood County. The project should be constructed in accordance with your application dated May
17, 2002 (received May 22, 2002). After reviewing your application, we have decided that this fill is
covered by General Water Quality Certification No. 3375 corresponding to the U.S. Army Corps of
Engineers Nationwide Permit Number 14. In addition, you should 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 only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us, in writing, and 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 wetland fills for this project
(now or in the future) exceed one acre or stream impacts 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. NCDOT shall implement Best Management Practices for the Protection of Surface Waters (NCDOT
March 1997) and Sedimentation and Erosion Control Guidelines for Sensitive Watersheds (15A
NCAC 4B .0024) prior to any ground-disturbing activities to minimize impacts to downstream
aquatic resources. Temporary or permanent herbaceous vegetation shall be planted on all bare soil
within 10 days of ground-disturbing activities (due to the presence of B waters) to provide long term
erosion control.
2. Where practicable, storm water should be directed to buffer areas or retention basins and must not be
routed directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that
they may be utilized for storm water sheet flow.
3. The pipes required for this project shall be installed in such a manner that the original stream profiles
are not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed).
Existing stream dimensions are to be maintained above and below locations of each culvert. The
culvert shall be installed one foot below the stream to allow for fish and other wildlife movement. If
the existing pipe is perched, it shall be removed and replaced, and installed correctly.
4. All work shall be performed during low flow conditions.

5. 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.
6. 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.
7. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted
when practical. If necessary, rip-rap must be limited to the stream bank below the high water mark,
and vegetation must be used for stabilization above high water.
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. 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.
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 that 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 Ms. Cynthia Van Der Wiele at 919.733.5715 or Mr.

Attention: Mr. John Hendrix
Subject: Proposed Construction of SR 1251 in Haywood Co.
State Project No. 6.942144(DWQ Minor Permit Fee $200.00)
Dear Mr. Hendrix:
The North Carolina Department of Transportation is proposing to grade, drain, base and
pave primarily along the existing roadway of SR 1251, Chestnut Park Rd. in Haywood County.
In order to construct this project in accordance with our current secondary road standards, and'
due to the extension of one (1) pipe culvert in an unnamed tributary to Richland Creek (DEM
Class B), we are requesting authorization under Section 404 of the Clean Water Act.
I am sending a straight-line diagram with our proposed erosion control and construction
limits at various sites along this project. In addition, a typical section of the road, drawings for
the culvert extension in the unnamed tributary to Richland Creek, general notes and standards
on erosion control measures, and a marked County Map are enclosed. We propose to install
the new culvert slightly below the existing stream bed elevation where bedrock is not
encountered to minimize impact to Wildlife habitat and allow the existing stream gradient to
remain as unchanged as physically possible.
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 controls are being effectively controlled. If the planned
devices are not functioning as intended, they will immediately be replaced with better devices.
The silt fences and other erosion control devices will be in place prior to pipe installation and will
remain in place until the project is stabilized.

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
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.ne.us/ncwetlands/stnngide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
.description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

Page 8 of 12
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http•//h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
