APPROVAL of 401 Water Quality Certification with Additional Conditions: MODIFICATION
Mr. Mike Pettyjohn, P.E.
Division Engineer WETLANDS GROUP
N C Department of Transportation
Post Office Box 250
North Wilkesboro, North Carolina 28659 DEC 1 .9 X003
Dear Mr. Pettyjohn: WATER QUALM SECF'l0IV
You have our approval, in accordance with the attached conditions and those listed below, to incur new impacts to
0.0847 acres of wetland in addition to the 99 linear feet of previously authorized impacts to unnamed tributaries to
Helton Creek (59 feet of new pipe and 40 feet of riprap) in order to improve SR 1527A (Helton Creek Road) in Ashe
County. The project must be constructed in accordance with your original application dated April 18, 2002 (received
April 26, 2002) and the new application dated October 22, 2003, (received October 24, 2003), 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 Nos. 3404 and 3366, corresponding to the U.S. Army Corps
of Engineers Nationwide Permit Numbers 14 and 33. 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 of 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
water 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 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 Division of Land Resources has
released the project.
4. Helton Creek and its tributaries are classified as C-trout + waters. NCDOT shall use Best Management Practices
for the Protection of Surface Waters (NCDOT March 1997) and Sedimentation and Erosion Control Guidelines for
Sensitive Watersheds [15ANCAC 4B.0124 (a)-(d)].
5. The "+" indicates that these streams are subject to special management conditions and drain to Outstanding
Resource Waters according to the DWQ stream classification schedule. You will be required to contact WRC to
determine what, if any, special management conditions apply to this location.
6. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 10 days of ground
disturbing activities to provide long-term erosion control. NCDOT is encouraged to use onsite vegetation and
materials for streambank stabilization when practicable.
7. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the trout spawning
season of October 15 through April 15, to protect the egg and fry stages of trout from off-site sedimentation,
during construction.
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 sheet flow.
10. Where fish passage is present or where significant aquatic life may be present upstream (and where practicable),
culverts should be oversized and buried to prevent perched culverts. If oversized piping cannot restore aquatic life
passage by reconnecting the stream ecosystem, riprap installation should be accomplished in a manner to provide
or restore water channels downstream to help facilitate aquatic life movement.
11. Where practicable, 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 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. These
measurements must be based on natural thalweg depths. 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. All waters must flow
through without freefalling or damming on either end of the culverts during low flow conditions, to maintain
aquatic life and/or fish passage.
12. The dimension, pattern and profile of the stream, above and below the crossing, 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.
13. Any riprap used must not interfere with aquatic life passage during low flow conditions.
14. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water. This will
lessen the chance of altering the stream's water chemistry and causing a fish kill.
15. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize
sedimentation and reduce,the likelihood of introducing other pollutants into the stream.
16. 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.
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 culverts.

Mr. Mike Pettyjohn

18. All work shall be performed during low flow conditions.
19. 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.

Subject: Nationwide Permit #14 MODIFRICATION
SR 1527A (Helton Creek Road)
Ashe County, North Carolina
Project Number: 110.005022 (DWQ Permit Fee: $200)
Dear Mr. Thomas:
On April 18, 2002, The NC Department of Transportation requested a permit to grade, drain,
base and pave SR 1527A in Ashe County. Since that time additional right-of-way has be acquired
through stations 37+50 - 44+00. A driveway running parallel to the roadway near station 38+00
will prevent widening on the cut side since doing so will undercut the above noted driveway. As a
result, construction of this section will require filling a small part of a bottomland hardwood forest
adjacent to the toe of the fill slope. Total wetland fill will be 0.0847 acres.
Construction of this project will require impacts to waters of the United States in the New River
Basin. This project was reviewed for the presence of threatened and endangered species on
March 6, 2002. The subject project will have no effect on any federally listed endangered plant or
animal species. According to the NCDOT web site, the NCDOT Historical Architecture Section
has reviewed this project and determined that there are no NR/SL/DOE properties along this
roadway that will be impacted by the proposed project.
Since this is an existing roadway, the minor modifications proposed in this application should not
remove or degrade existing water quality uses. By utilizing the erosion control measures outlined
in the initial erosion control plan, downstream water quality standards will be protected. All
appropriate BMPs will be used during construction.

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.nc.us/ncwetlands/strmgide.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

DWQ Project No. 020651
SR 1527A (Helton Creek Road)
APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. Heath Slaughter, Division Environmental Officer
NCDOT Division 11
P.O. Box 250
North Wilkesboro, NC 28659
Dear Mr. Slaughter:
You have our approval, in accordance with the attached conditions and those listed below, to impact
99 linear feet of unnamed tributaries to Helton Creek in order to improve SR 1527A (Helton Creek
Road) in Ashe County. The project must be constructed in accordance with your application dated
April 18, 2002 (received April 26, 2002). After reviewing your application, we have decided that this
fill is covered by General Water Qu4lity Certification No. 3375, 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 of 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 mast follow the conditions listed in the
attached certification and any additional conditions listed belotiv.
1. NCDOT shall use 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) must be implemented 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 to provide long term
erosion control.
2. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the
trout spawning season of October 15 through April 15, or other conditions as determined by the
North Carolina Wildlife Resources Commission, to protect the egg and fry stages of trout from
sedimentation during construction.
3. Riparian vegetation must be reestablished within the construction limits of the project by the end
of the growing season following completion of construction.
4. NCDOT is encouraged to use existing on-site vegetation and materials for stream bank
stabilization and to minimize the use of rip rap. i

Dear Mr. Slaughter:
You have our approval, in accordance with the attached conditions and those listed below, to impact
99 linear feet of unnamed tributaries to Helton Creek in order to improve SR 1527A (Helton Creek
Road) in Ashe County. The project must be constructed in accordance with your application dated
April 18, 2002 (received April 26, 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 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 of 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. NCDOT shall use 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) must be implemented prior to any ground-disturbing activities to minimize
impacts To downsfream aquatic resources. Temporary or permanent herbaceous vegetation shall
be planted on all bare soil within 10 days of ground-disturbing activities to provide long term
erosion control.
2. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the
trout spawning season of October 15 through April 15, or other conditions as determined by the
North Carolina Wildlife Resources Commission, to protect the egg and fry stages of trout from
sedimentation during construction.
3. Riparian vegetation must be reestablished within the construction limits of the project by the end
of the growing season following completion of construction.

Subject: Nationwide Permit #14
SR 1527A (Helton Creek Road)
Ashe County, North Carolina
Project Number: 6.712089T (DWQ Permit Fee: $200)
Dear Mrs. Manuele:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1527A in
Ashe County. Total project length is approximately 1.25 miles. This project will require the
replacement of four (4) wet cross lines as shown below:
1) Replace existing 24'x 24" CMP at station 1+67 with a 45'x 24" CMP.
2) Replace existing 32'x 24" CMP at station 27+69 with a 45'x 36" CMP.
3) Replace existing 35'x 24" CMP at station 35+58 with a 45'x 24" CMP.
4) Replace existing 25'x 24" CMP at station 61+45 with a 40'x 24" CMP.
Miscellaneous rip-rap impacts will total 40 linear feet or less. New stream impacts = 91n. feet.
Construction of this project will necessitate impacts to waters of the United States in the New
River Basin. Each of the above noted wet cross lines carry different unnamed tributaries to
Helton Creek (Class: C, Trout +). The Division 11 Environmental Officer reviewed this project
for the presence of threatened and endangered species on March 6, 2002. The subject project has
been determined to have no effect on any federally listed endangered plant or animal species.
According to the NCDOT web site, the NCDOT Historical Architecture Section has reviewed
this project and determined that there are no NR/SL/DOE properties along this roadway that will
be impacted by the proposed project (see attachment).

Since this is an existing roadway, the minor modifications proposed in this application should not
remove or degrade existing water quality uses. Any widening of the existing roadway will be
directed away from any adjacent creek whenever possible with minimum fill placed in any buffer
area. Pipe sizes used will be the minimum necessary to create a safe roadway. By utilizing the
erosion control measures outlined in the attachments to this application, downstream water
quality standards will be protected. All appropriate BMPs will be used during construction.
Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control
measures, a marked county map, a marked topography map and photographs.
By copy of this letter, it is requested that Mr. Ron Linville, Mountain Region Coordinator, with
the North Carolina Wildlife Resources Commission comment directly to you concerning the 404
Nationwide Permit application with a copy sent to me. Please note that a buffer zone
encroachment variance will be requested from stations 3+00 - 12+50, 17+50 - 34+00, 43+50 -
47+00 and 53+00 - 60+00. The centerline of the road will be shifted 4' away from the creek
through these areas (see attached cross-sections).
By copy of this letter, I am forwarding seven (7) copies of this application package to Cynthia
Van Der Wiele, NCDENR, Division of Water Quality, 401/Wetlands Unit, for her review. It is
requested that any comments related to the 401 certification be forwarded directly to me with a
copy sent to the US Army Corps of Engineers.
We would like to begin construction as soon as possible. If further information is required, please
let me know. Your early review and consideration will be appreciated.

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

TO: Jean Manuele, USACOE
Raleigh Regulatory Field Office
FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: Apri 125, 2002
SUBJECT: North Carolina Department of Transportation (NCDOT), NCSR1527A,
Unnamed Tributaries Helton Creek, Ashe County
NCDOT proposes to grade, drain, base, and pave primarily along the existing Helton
Creek Road right-of-way. Biologists with the North Carolina Wildlife Resources
Commission are familiar with habitat values in the area. These comments are provided in
accordance with the provisions of the Fish and Wildlife Coordination Act (48 Stat. 401,
as amended; 16 U.S.C. 661-667d) and the North Carolina Environmental Policy Act
(G.S. 113A-1 through 113A-10; NCAC 25).
NCDOT proposes to replace and upsize several existing culverts while completing the
project. Miscellaneous riprap impacts are indicated to be 40 linear feet. Total new
stream impacts will be 99 linear feet. Helton Creek is Delayed Harvest trout water. The
creek supports wild rainbow and brown trout.
Based on our review of the submittal and our knowledge of trout in the area, we will not
object to the project provided the following conditions are implemented:
1. Instream work and land disturbance within the 25-foot wide buffer zone are
prohibited during the trout spawning seasons of October 15 through April 15
to protect the egg and fry stages of trout.
2. The use of riprap in the channel should be avoided to the extent practicable.
3. Culverts 48" or larger should be buried approximately F into the streambed.
Culverts less than 48 inches in diameter should be buried to a depth equal to
NCSR 1527A, Helton Creek Road 2 April 25, 2002
or greater than 20% their size to allow for aquatic life passage. The
dimension, pattern, and profile of the streams should not be modified by
widening the stream channel or reducing the depth of the stream. Previously
disturbed floodplains and streams should be restored to natural geomorphic
conditions whenever practicable.
2. If any concrete will be used, work must be accomplished so that wet concrete
does not contact stream water. This will lessen the chance of altering the
stream's water chemistry and causing a fish kill.
3. Heavy equipment should be operated from the bank rather than in the stream
channel in order to minimize sedimentation and reduce the likelihood of
introducing other pollutants into the stream.
4. Stringent erosion control measures should be installed where soil is disturbed
and maintained until project completion.
5. 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. We encourage NCDOT to utilize onsite vegetation and materials for
streambank stabilization when practicable.
Thank you for the opportunity to review and comment on this project during the early
planning stages. If you have any questions regarding these comments, please contact me
at 336/769-9453.
