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 40
linear feet of unnamed tributaries to Bill White Creek in order to improve SR 1145 (H. M. Homey Road)
in Avery County. The project must be constructed in accordance with your application dated May 29,
2002 (received June 3, 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. Riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
2. NCDOT is encouraged to use existing on-site vegetation and materials for stream bank stabilization
and to minimize the use of rip rap.
3. The dimension, pattern, and profile of the stream and floodplain above and below the structure shall
not be modified by widening the stream channel or reducing the depth of the stream.
4. Culverts 48" and larger should be buried approximately one foot into the streambed. Culverts less
than 48" in diameter should be buried to a depth equal to, or greater than, 20% of their size to allow
for passage of aquatic life. ,
5. Previously disturbed floodplains and stream channels should be restored to their natural geomorphic
conditions whenever practicable.
6. All work shall be performed during low flow conditions.
7. 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.
8. 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 MAT,
materials.

SR 1145 (H. M. Homey Road) UED
Avery County, North Carolina -- -
Project Number: 6.722285 (DWQ Permit Fee: $200)
Dear Mrs. Manuele:
The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1145 in ,
Avery County. The roadway will be widened from 12 feet to 16 feet. This project will also
require the replacement of two (2) wet cross lines as shown below:
1) Replace existing 30'x 15" CMP at station 13+65 with a 40'x 18" CMP.
2) Replace existing 30'x 24" CMP at station 17+50 with a 40'x 36" CMP.
Miscellaneous rip-rap impacts will total 20 linear ft. or less. New stream impacts = 40 linear feet.
Construction of this project will necessitate impacts to waters of the United States in the Catawba
River Basin. Both of the above noted cross lines carry different unnamed tributaries to Bill White
Creek (Class: Q. The Division 11 Environmental Officer reviewed this project for the presence
of threatened and endangered species on May 16, 2002. The subject project will have no effect
on any federally listed endangered plant or animal species. Historic compliance work will be
scheduled and concurrence with the State Historic Preservation Office will be obtained if
required.
The project impacts are minor in nature and should not remove or degrade existing water quality
uses. 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.

VIII. Mitigation
S
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 C4rolina, 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
a separate sheet if more space is needed.

PIPE INSTALLATION
1. Install erosion control devices. In streams, where necessary, rock silt
`screens will be used and installed prior to pipe replacement or any
work being done to channel.
2. Remove material and existing pipe while limiting, as much as
possible, material and sediment from entering a stream and/or
escaping from project.
3. Prepare pipe foundation while again taking care to limit, as much as
possible, material and sediment from entering a stream and/or
escaping from project. Where possible, new grade will be below
existing stream bed. If needed, bedding material will be clean stone.
4. Place the new pipe and compact backfill.
5. Install slope protection on outlet and inlet ends of pipe. Also
complete installation of erosion control measures and perform
maintenance as needed on existing measure.
6. Establish permanent vegetation as soon as possible.
7. Remove rock silt screens as soon as possible after vegetation is
established. Prior to removal of rock silt screens any accumulated silt
must be removed.
GENERAL NOTES ON EROSION CONTROL
a
Silt Basin Type B's will be constructed to the dimension of six feet by three
feet by three feet unless otherwise noted on the plans.
Where slope protection treatment is required, Section 868 and Section 1042 of
the 1990 Standard Specifications for Roads and Structures will be followed.
Any material obtained from the project must be clean before being placed.
Generally, the order of installation of the erosion control measures will be as
follows:
Temporary Silt Basins shall be installed before clearing and
grubbing begins.
Silt Fences and Temporary Silt Ditches shall be installed after
clearing and before grading.
Temporary Stone Ditch Checks shall be installed as soon as
ditchline is established.
Pipe Outlet and Inlet Protection will be done as soon as the pipe
is installed.
Seeding and other permanent erosion control measures are to be
implemented as soon as practical.

Raleigh Regulatory Field Office
FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: June 10, 2002
SUBJECT: North Carolina Department of Transportation (NCDOT), SRI 145, UT Bill White Creek,
Avery County
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). The NCDOT proposes to replace two (2) existing
CMPs with larger diameter CMPs. Additional impacts will be 20 linear feet of pipe and 20 linear feet of
riprap.
We will not object to the project provided the following conditions are implemented:
1. Culverts less than 48 inches in diameter should be buried to a depth equal to or greater than
20% their size to allow for aquatic life passage. These measurements must be based on
natural thalweg depths.
2. The dimension, pattern, and profile of the stream above and below the pipes 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.
3. If 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.
4. 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.
5. Stringent erosion control measures should be installed where soil is disturbed and maintained
until project completion.
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. 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.
