NORTH CAROLINA 401 WATER QUALITY CERTIFICATION
THIS CERTIFICATION is issued in conformity with the requirements of Section 401
Public Laws 92-500 and 95-217 of the United States and subject to the North Carolina Division
of Water Quality (DWQ) Regulations in 15 NCAC 2H, Section .0500. It is issued to N.C.
Division of Water Resources to dredge 529,000 cubic yards of material in Dare County pursuant
to an application filed on the 15' day of December 1998 to conduct maintenance dredging in
Roanoke Sound and Shallowbag Bay.
The application provides adequate assurance that the discharge of fill material into the
waters of Roanoke Sound and Shallowbag Bay in conjunction with the proposed development
will not result in a violation of applicable Water Quality Standards and discharge guidelines.
Therefore, the State of North Carolina certifies that this activity will not violate the applicable
portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in
accordance with the application and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your
application, as described in the Public Notice. If you change your project, you must notify us
and send us a new application for a new certification. If the property is sold, the new owner must
be given a copy of the 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,
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 below. In addition, you
should get any other federal, state or local permits before you go ahead with your project
including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge
and Water Supply watershed regulations.
Condition(s) of Certification:
Appropriate sediment and erosion control practices which equal or exceed those
outlined in the most recent version of two manuals. Either the "North Carolina
Sediment and Erosion Control Planning and Design Manual" or the "North Carolina
Surface Mining Manual" (available from the Division of Land Resources in the
DEHNR Regional or Central Offices). The control practices shall be utilized to prevent
exceedances of the appropriate turbidity water quality standard (50 NTUs in all fresh
water streams and rivers not designated as trout waters; 25 NTUs in all lakes and
reservoirs, and all saltwater classes; and 10 NTUs in trout waters);
2. All sediment and erosion control measures placed in wetlands or waters shall be
removed and the natural grade restored after the Division of Land Resources has
released the project;
3. Measures shall be taken to prevent live or fresh concrete from coming into contact with
waters of the state until the concrete has hardened;
4. Should waste or borrow sites be located in wetlands or other waters, compensatory
mitigation
will be required since it is a direct impact from road construction activities;
x
5. A minimum two foot free board shall be maintained in all upland diked disposal sites at
all times.
6. A post-dredging survey shall be submitted to DWQ's Washington Regional Office
within 30 days of the completion of the project.
7. Dredging depth must be maintained at a depth of twelve feet for the Manteo to
Wanchese channel and 10 feet for the North channel. A maximum of two foot
overdredge is allowable for this project.
Violations of any condition herein set forth shall result in revocation of this Certification
and may result in criminal and/or civil penalties. This Certification shall become null and void
unless the above conditions are made conditions of the Federal 404 and/or coastal Area
Management Act Permit. This Certification shall expire upon expiration of the 404 or CAMA
permit.
If this Certification is unacceptable to you have the right to an adjudicatory hearing upon
written request within sixty (60) days following receipt of this Certification. This request must
be in the form of a written petition conforming to Chapter 150B of the North Carolina General
Statutes and filed with the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C.
27611-7447. If modifications are made to an original Certification, you have the right to an
adjudicatory hearing on the modifications upon written request within sixty (60) days following
receipt of the Certification. Unless such demands are made, this Certification shall be final and
binding.
This the 26' day of January 1998

Raleigh, North Carolina 27607
Dear Mr. Dorney:
DEC l 5
i
Please reference the application of the North Carolina Division of Water Resources for
Department of the Army (DA) authorization and a State Water Quality. Certification to undertake
maintenance dredging activities within Roanoke Sound and Shallowbag Bay, located near Nags
Head and Manteo, in Dare County, North Carolina. Your receipt of this letter verifies your
acceptance of a valid request for certification in accordance with Section 325.2(b)(ii) of our
administrative regulations.
We are considering authorizing the proposed activity pursuant to Section 404 of the Clean
Water Act, and we have determined that a water quality certification is required under the
provisions of Section 401 of the same law. A Department of the Army permit will not be
granted until the certification has been obtained or waived.
In accordance with our administrative regulations, in most cases, 60 days after receipt
of a request for certification is a reasonable time for State action. Therefore, if you have
not acted on the request, or asked for an extension of time, by February 4, 1999, the
District Engineer will deem that waiver has occurred.
Questions or comments may be addressed to Mr. Raleigh Bland, Washington Regulatory
Field Office, Regulatory Division, telephone [phone], extension 23.
Sincerely,
Raleigh Bland, P.W.S.

Maintenance Dredging of Manteo to
Wanchese and North Channels
Project Description
Purpose
The purpose of this project is to perform maintenance dredging of the Manteo to
Wanchese and North navigation channels. This maintenance will provide safe navigation for
boats and ships, including the Elizabeth II, the State historic ship which draws approximately 8.5
feet of water. The locations of these channels are shown in Figure 1. Complete dredging of the
Manteo to Wanchese channel was last done in 1985; partial dredging of the North channel was
done in 1989; and shoals in both channels were dredged in 1994.
Use
The Manteo to Wanchese and North Navigation Channels are used by the Elizabeth II,
recreational power and sailboats, fishing boats, and tour and party boats. Dare County is trying
to attract some of the boats and ships traveling the Intercoastal Waterway from the Alligator
River Channel to the North and Manteo to Wanchese Channels. The maintenance of these two
channels is critical to this effort. It is also critical for,the efficient operation and sailing of the
Elizabeth II, which has been hitting bottom when trying to use these channels. The Manteo to
Wanchese and North channels were authorized to be 12 feet and 10 feet deep, mean low water,
respectively. For the past 14 years, however, the State has maintained the Manteo to Wanchese
Channel to 10 feet deep, and the North Channel to 9 feet. The proposed dredging would deepen
the Manteo to Wanchese channel to 12 feet, and the North Channel to 10 feet. The current
controlling depths of these two channels are approximately 6.0 feet and 5.0 feet, mean low water,
respectively.
Methods of Construction
The maintenance dredging of these two channels will be accomplished using a hydraulic
dredge with a cutter head that breaks up the bottom so that it can be transported in a slurry
through a pipeline. The disposal site for material pumped from the North Channel (and possibly
a portion of the Manteo to Wanchese Channel south of the Highway 64-264 Bridge) will be to
Nags Head beach. The pipeline will pass under major highways through culverts. See Figures 2
through 7. The disposal site for material from the Manteo to Wanchese Channel will be high
ground diked areas located on Roanoke Island shown in Figures 8 through 13. Volumes of the
high ground sites are listed in Table 1. The water in the pipeline will drain into the ocean during
beach disposal and drain into either Shallowbag Bay or Croatan Sound during high ground
disposal. The material placed on the beach will be shaped by a bulldozer to create a berm
approximately 75 wide as shown in Figure 7. The material placed in the high ground disposal
areas, after the water in these areas is allowed to drain away, will be mixed with the sandy
material in the dikes and then leveled and seeded. Sedimentation and erosion control measures
will be employed during dike construction and throughout the dredging period.
