APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. M. L. Holder, P.E.
Division Engineer
N. C. Department of Transportation
Post Office Box 47
Shelby, North Carolina 28151-0047
Dear Mr. Holder:
You have our approval, in accordance with the attached conditions and those listed below, to impact two unnamed
tributaries to Lake Norman (29 linear feet of permanent impact and 60 linear feet of temporary impact for coffer dams) in
order to repair two undermined culverts on SR 1190 in Iredell County. The project must be constructed in accordance with
your application dated June 25, 2003 (received June 27, 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 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 211.0506 (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. Lake Norman and its tributaries are classified as WS-IV CA waters at these locations. NCDOT shall implement
Best Management Practices for the Protection of Surface Waters (NCDOT March 1997).
2. NCDOT shall comply with the requirements for WS-IV CA waters [15A NCAC 2B .0126 (3)(b) with regard to
riparian buffer requirements and stormwater controls.
3. All culverts 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 widening of the streambed). Existing stream dimensions
(including the pattern and profile) are to be maintained above and below locations of culvert extensions. The culvert
shall be designed to allow for fish and other wildlife movement as well as prevent headcutting of the streams.
4. NCDOT shall provide a written plan for stream stabilization should headcutting or destabilization result from these
construction activities.
5. The use of riprap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical. If
riprap is necessary, it must be limited to the stream bank above the high water mark. Riprap shall not be placed in the
stream bottom.
6. 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 materi

1-877-623-6748
7. All constructed stormwater conveyance outlets shall be directed to flow in a diffuse manner at non-erosive
velocities through the entire protected stream buffers without re-concentrating. If this is not possible it may
be necessary to provide stormwater facilities.
S. Riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of the project.
9. 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.
10. Upon completion of the project, the NCDOT or its authorized agent 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. Please include photographs of
the site.
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. Mike Parker of the Asheville Regional

The North Carolina Department of Transportation, Division of Highways, request the issuance of
a Section 404 Permit, Nationwide Permit 414, Linear Transportation Crossings, and 433,
Temporary Construction, Access, and Dewatering.
COUNTY: Iredell
LOCATION: Two sites on SR 1190, west of Mooresville
STREAM: Unnamed tributaries to Lake Norman, WS-1V CAWatershed (from Lyle
Creek to Cowan's Ford Dam), Catawba River Basin
PROJECT DESCRIPTION: The project consists of the replacement of two undermined pipes
on SR 1190. At the first site, a 50' long, 30" CMP will be replaced with a 60' long, 36" CMP
with five feet of riprap at outlet for structure protection. At the second site, a 60' long, 30" CMP
will be replaced with a 60' long, 36" CMP, also with five feet of riprap at outlet for structure
protection. There is a large scourhole at the pipe outlet of the first pipe that will be filled and
restructured to the normal upstream and downstream dimensions. A stream profile was
established by measuring the thalweg elevations at various points upstream and downstream of
the pipe. The proposed pipe will be buried 20% below the existing streambed elevation based
upon this profile. There is also a large scour hole at the outlet of the second pipe. The existing
pipe is perched approximately five feet above the scourhole bed elevation. A stream profile was

also established on the second unnamed tributary by measuring the thalweg elevations at several
several points upstream and downstream of the pipe. It was determined that the new pipe must be
installed on a 4.8% grade to position the pipe at the existing water level. The scourhole will be
left in place to act as a natural energy dissipater. Riprap will be embedded into the scour hole bed
in an effort to prevent future downcutting and stream destabilization. Both pipes will be installed
using the boring method since the road is a dead-end road in the heavily developed area
surrounding Lake Norman. Both projects are located further than 50 feet from the lake;
therefore, the 50-foot lake buffer will not be impacted. At both locations, the -200 square foot
staging area for the boring equipment will be located on the upstream side. It will temporarily
impact -20 linear feet of the stream. Temporary cofferdams will be utilized to manage the
watercourse during construction. Upon project completion, the area impacted by the temporary
cofferdams and temporary staging area will be restored to pre-construction conditions.
Appropriate erosion control measures will be in place during construction to protect downstream
water quality. I have enclosed a PCN application, a sketch of activities, and location maps
relative to the project.
The proposed project is located within a WS-IV CA watershed in the critical watershed area.
Based upon the "Guidelines for the Location and Design of Hazardous Spill Basins", which are
referenced in DOT's Best Management Practices for the Protection of Surface Waters, the
applicable locations for hazardous spill basins are at stream crossings on highways functionally
classified as a rural or urban arterial and where the stream crossing is within '/z mile of the critical
watershed area. Although the crossing is within the critical watershed area, SR 1190 is not
classified as a rural or urban arterial. Hazardous spill basins are not required for this project.
Enclosed is the NCDOT hazardous spill basin checklist.
A review of the Natural Heritage information for the T/SA species (threatened due to similarity of
appearance) listed for Iredell County, the bog turtle (Clemmys muhlernbergh), revealed no known
sites in the vicinity of the project areas. On-site surveys were conducted on August 13, 2002 and
April 22, 2003. Neither the bog turtle nor suitable habitat was observed at either project site. It
is anticipated that there will be no impact on this species or its habitat. A review of the available
information from the National Register of Historic Places was also conducted. It is anticipated
that no historic site will be impacted by the proposed project.
Your earliest consideration for this request would be greatly appreciated. Should you have any
questions, please call me at 704480-9020.

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.

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.
At both sites. there are large scour holes located at the existing pipe outlets. Due to the large size
of the scourhole at the first site, the scour hole will be filled and the stream channel restructured
to mimic the existing upstream and downstream dimensions. The existing pipe at the second site
is perched approximately five feet above the scourhole bed elevation. The new pipe is to be
placed at a 4.8% grade to position the pipe at existing water level. Due to this steep grade at
which the pipe will be placed, the scour hole at this site will be left to act as an energy dissipater.
Riprap will be embedded into the bed of the scour hole in an effort to prevent future downcutting
and stream destabilization. The replacement at both sites is to be done using the boring method
since SR 1190 is a dead-end road in the highly developed area surrounding Lake Norman.
Neither closure of the road nor the construction of a temporary detour is a viable option.

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/strm,izide.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.
IMPACTS < 150 FEET• MITIGATION NOT ANTICIPATED
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 littp://h2o.enr.st ite.nc.us/«-m/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
