APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Holder:
You have our approval, in accordance with the attached conditions and those listed below, to permanently
impact 120 linear feet (If) (60 If for culvert installation, 50 If for floodplain bench creation, and 10 If for
inlet/outlet stabilization using riprap) and temporarily impact 40 If (temporary cofferdam installation) of
Robinette Creek, a perennial stream. The impacts are proposed in order to replace a deteriorating bridge with
a double barrel concrete culvert as described in your application received by the Division of Water Quality
(DWQ) on August 22, 2005. The location of the project is State Road 1310 (Robinette Road) in Alexander
County. After reviewing your application, we have determined that this project is covered by Water Quality
General Certification Number 3404. This certification corresponds to Regional General Permit 198200031
issued by the U.S. Army Corps of Engineers (USACE). Please note that you should get any other federal,
state or local permits before proceeding with your project, including those required by (but not limited to)
Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed regulations.
This approval is valid solely for the purpose and design that you described in your application (unless modified
below) and will expire with the associated USACE 404 permit unless otherwise specified in the Water Quality
Certification. Should your project change, you must notify the DWQ in writing and you may be required to
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 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 remain valid, you must adhere to the conditions listed in the attached certification and those listed
below:
Due to the streambed elevation at the inlet end of the proposed culvert, DWQ will not require the burial of the
culvert in the streambed at the inlet end of the pipe. The outlet end of the pipe must be placed below the
elevation of the streambed by one foot to allow for low flow passage of water and aquatic life. All structures
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). Design and placement of culverts and other
structures including temporary erosion control measures 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 (including pattern and profile) are to be maintained above and
below locations of each culvert. The applicant may be required to provide evidence that the equilibrium has
been maintained, if requested in writing by the DWQ.

2. Riprap must not interfere with thalweg performance and aquatic life passage during low flow conditions.
3. Disposal of old bridge material into surface waters is not allowed. Strict adherence to the USACE guidelines
for bridge demolition will be required.
4. Erosion and sediment control practices must utilize Best Management Practices (BMP) and be in full
compliance with all specifications governing the proper design, installation, and operation and maintenance of
such BMP in order to protect surface water standards:
a. 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 pit sites, and waste pile (spoil)
projects, including contractor-owned or leased borrow pits associated with the project.
b. 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.
c. The reclamation measures and implementation of these measures must be in accordance with the
requirements of the Sedimentation Pollution Control Act.
5. Heavy equipment must be operated from the banks rather than in the stream channel, when possible, in
order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream.
6. Temporary dewatering sites must be restored to pre-existing conditions unless more natural geomorphic
conditions can be provided.
7. No live or fresh concrete shall come into contact with waters of the state until the concrete has hardened.
8. The dimension, pattern and profile of the stream above and below the crossing should not be modified.
Disturbed floodplains and streams should be restored to natural geomorphic conditions.
9. 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.
10. All work shall be performed during low or normal flow conditions.
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited.
12. 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 30 days after the Division of Land Resources has
released the project.
13. The North Carolina Department of Transportation (NCDOT) and its contractors and/or agents shall not
excavate, fill or perform mechanized land clearing at any time in the construction or maintenance of this
project within waters and/or wetlands, except as authorized by this Certification, or any modification to this
Certification (e.g., no work shall occur outside of the footprint of the plans provided). In addition, there shall
be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this
Certification without appropriate modification. If this occurs, compensatory mitigation may be required since it
is a direct impact from road construction activities.

Page.3
14. Upon completion of the project, the applicant shall complete and return the enclosed "Certificate of
Completion" form to notify DWQ when all work included in the 401 Certification has been completed. Please
include photographs upstream and downstream of the structure to document correct installation.
15. Continuing Compliance. NCDOT shall conduct its activities in a manner so as not to contravene any state
water quality standard [including any requirements for compliance with section 303(d) of the Clean Water Act]
and any other appropriate requirements of state and federal law. If DWQ determines that such standards or
laws are not being met (including the failure to sustain a designated or achieved use) or that state or federal
law is being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate
and modify this certification to include conditions appropriate to assure compliance with such standards and
requirements in accordance with 15 A NCAC 2H.0507(d). Before codifying the certification, DWQ shall notify
NCDOT and the USACE, provide public notice in accordance with 15A NCAC 2H.0503, and provide
opportunity for public hearing in accordance with 15A NCAC 2H.0504. Any new or revised conditions shall
be provided to NCDOT in writing, shall be provided to the USACE for reference in any permit issued pursuant
to Section 404 of the Clean Water Act, and shall also become conditions of the 404 Permit for 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

SUBJECT: Bridge #85 replacement, SR 1310 (Robinette Rd), Alexander County
Dear W. Lund:
The North Carolina Department of Transportation requests authorization to replace a deteriorating bridge
on SR 1310 (Robinette Rd) in Alexander County. NCDOT proposes to replace the existing 20' x 20'
bridge with a 60-foot long, double CMPA. The main flow pipe dimensions are 142" x 91" and the
flood flow pipe dimensions are 117" x 79". Although, the stream in the immediate vicinity of the
bridge is not a steep gradient section, the project site is located in the Brushy Mountain area of northern
Alexander County and there is a steeper gradient section upstream of the bridge that appears to have a
definite riffle/pool sequence (see attached upstream photo). The scope of work will result in permanent
fill impacts to Robinette Creek, which is classified as Class B waters by the Division of Water Quality.
A thalweg profile was conducted to determine the streambed elevations on which to base the one-foot
pipe burial. It was discovered that the proposed pipe inlet invert, if placed one foot below the existing
streambed elevation would be lower than the proposed pipe outlet invert elevation. (See enclosed sketch
sheet 4 with thalweg and proposed pipe elevations). Therefore, based upon the existing streambed
elevations, it is proposed that the main flow pipe inlet be placed on streambed grade and the pipe outlet be
buried one foot below the existing streambed elevation. The flood flow pipe will be placed - one foot
higher than the main flow pipe. Riprap faced bankfull benches will be constructed upstream and
downstream of the flood flow pipe to maintain normal channel dimensions and direct flow through the
main flow pipe. Stream destabilization does not appear to be an issue based upon the calculated slopes of
the existing stream and the proposed pipe.
Temporary cofferdams will be necessary for the staged construction of the double pipe. Upon
construction completion, areas impacted by the cofferdams will be restored to pre project conditions.

Pond Creation: NO POND IMPACTS
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands

local stormwater requirement, etc.):.
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
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.
Due to the financial considerations, the lower cost alternative of the double pipe is proposed for
this bridge replacement A bottomless arched culvert was also considered for this location;
however, borings of the site indicated that the bedrock in the area was too deep. A stream survey
was conducted (thalwegprofile and upstream/downstream cross-sections) to determine adequate
pine sizes to carry normal stream flow and bankfull flow. The "normal" stream width was
determined to be -12 feet' therefore a 142" wide pipe will be installed for the main flow
channel Bankfull width was determined to be -20 feet; therefore, the second flood flow Ripe
will 11 T' wide which will provide a 21 foot bankfull width.
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.
Page 5 of 9
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/strmaide.htmi.
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.
