APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Gregory Taylor
Town of Ocean Isle Beach
3 West Third Street
Ocean Isle, NC 28469
Dear Mr. Taylor:
You have our approval, in accordance with the attached conditions and those listed
below, to dredge up to 625,000 square feet of bottoms for the purpose of performing
maintenance dredging in canals along the AIWW in Ocean Isle as described in your
application dated November 27, 2000 as revised on March 6, 2001. After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification
Number 3274. 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 Water shed regulations. This
approval will expire when the accompanying 404 or CAMA permit expires unless
otherwise specified in the General 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 and you
may be required to 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,
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.
Dredging shall be done as modified in the March 6, 2001 letter from Criser and Troutman
Consulting Engineers.
2. Upon completion of the project, the party in question shall complete and return the
enclosed "Certification of Completion Form" to notify DWQ that all the 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 Division of Water Quality.
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, P.O. Box 27447,
Raleigh, N.C. 27611-7447. This certification and its conditions are final and binding unless
you ask for a hearing.

Re: Dredge Permit Application
Town of Ocean Isle Beach, NC
DWQ Project #001482 (Brunswick County)
COE# 200100169
Dear Mr. Dorney:
In response to your letter dated January 16, 2001, and on behalf of the Town of
Ocean Isle Beach, North Carolina, we offer this letter in response to your preliminary
comments and the attached revised drawings.
We have spoken with the Town concerning the proposed width of 40' for canal
#21 and propose to change the canal width from 40' to 25' feet as an alternative dredge
design width with the eastern edge of the dredge cut remaining in the same location.
We feel that this revised width will protect against taking any of the wetlands during
dredging and would also be a minimum width that the Town could live with. We have
also indicated that the dredge limits would shift accordingly where the canal necks-
down in order to prevent disturbing of wetlands.
We also propose to stabilize the existing 12" diameter CMP stormwater pipe
located at the head of Canal #21 by requiring installation rip-rap in order to prevent
further erosion around the pipe. The base of the rip-rap would terminate at the end of
the pipe and would taper back to meet existing grade. See details on attached drawing.
Please let me know if additional drawings are required for your further review
or if you need additional information, as the Town desires to actively pursue this
project. Otherwise, we trust that you have sufficient information stating our
clarifications to the permit application.

CERTIFIED MAIL-RETURN RECEIPT REQUESTED
Mr. Gregory Taylor
Town of Ocean Isle Beach
3 West Third Street
Ocean Isle Beach, NC 28469
Dear Mr. Taylor:
The Division of Water Quality has reviewed your plans to dredge 652,000 square feet of bottom
located at canals between Caseway Drive and Concord Street in Brunswick County for maintenance
dredging as described in your application dated November 27, 2000. Insufficient evidence is present in our
files to conclude that your project must be built as planned in waters and/or wetlands in accordance with
15A NCAC 2H .0506. Therefore, unless modifications of the proposal are made as described below, we
will have to move toward denial of your 401 Certification as required by 15A NCAC 2H .0507(e) and will
place this project on hold as incomplete until we receive this additional information, we are requesting (by
copy of this letter) that the U.S. Army Corps of Engineers place your project on administrative hold.
Please provide us with information supporting your position that states your project must be
constructed as planned and that you have no practicable alternative to placing fill in these waters and/or
wetlands. Specifically can you narrow the proposed dredging of canal #21 in order to protect the wetlands
found in this area? Also the head of the canal will need to be stabilized to prevent erosion from the
stormwater pipe. Any documentation such as maps and narrative that you can supply to address alternative
designs for your project may be helpful in our review of your 401 Certification.
Please respond within three weeks of the date of this letter by sending a copy of this information.to
me and Ms. Joanne Steenhuis, of the Wilmington Regional Office at [phone]. If we do not hear
from you in three weeks, we will assume that you no longer want to pursue this project and we will consider
the project as withdrawn. I can be reached at 919-733-9646 if you have any questions.

Re: Dredge Permit Application

Dear Mr. Dorney: COE* 200100169
In response to your letter dated January 16, 2001, and on behalf of the Town of
Ocean Isle Beach, North Carolina, we offer this letter in response to your prelin teary
comments and the attached revised drawings.

We have spoken with the Town concerning the proposed width of 40' for canal
#21 and propose to change the canal width from 401 to 25' feet as an alternative dredge
design width with the eastern edge of the dredge cut remaining in the same location.
We feel that this revised width will protect against taking any of the wetlands during
dredging and would also be a minimum width that the Town could live with, We have
also indicated that the dredge limits would shift accordingly where the canal necks-
down in order to prevent disturbing of wetlands.
We also propose to stabilize the existing 1211 diameter CMP storrnwater pipe
located at the head of Canal #21 by requiring installation rip-rap in order to prevent
further erosion around the pipe, The base of the rip_rap would ten"inatie at the end of
the pipe and would taper back to meet existing grade. See details on attached drawing.
Please let me know if additional drawings are required for your further review
or if you need additional information, as the Town desires to actively pursue this
Project Otherwise, we trust that you have sufficient information stAting our
clarifications to the permit application.

Dear Mr. Haggett:
Reference the application of the Town of Ocean Isle Beach for a Department of the Army
permit to perform maintenance dredging on a man-made canal system along with entrance
channels of the Atlantic Intracoastal Waterway in Ocean Isle Beach, Brunswick County, North
Carolina.
The Federal agencies have completed review of the proposal as presented by the application
and your field investigation report.
We recommend that the following conditions be included in the State authorization:
1. In order to protect juvenile fish populations, no excavation or filling will be permitted
between the dates of April I and September 30 of any year without the prior approval of the
North Carolina Division of Coastal Management.
2. All excavated materials will be confined landward of the mean high water (MHW)
elevation contour and any regularly or irregularly flooded vegetated wetlands.
3. All excavated materials will be confined landward of the mean high water (MHW)
elevation contour within adequate dikes or other retaining structures to prevent spillover of solids
into any vegetated wetlands or surrounding waters.
4. The terminal end of the pipeline from the dredge into the diked retention area will be
positioned at or greater than 50 feet from any part of the dike and a maximum distance from
spillways to prevent dike erosion and to allow adequate settlement of suspended solids.
5. A water control structure will be installed at the intake end of the effluent pipe leading
from the retention area in order to ensure maximum settlement of suspended solids.
No excavated or fill materials will be placed at any time in any vegetated wetlands or
waters.
7. No vegetated wetlands will be excavated or filled.
8. Excavation will not exceed -6 feet below the elevation of mean low water (MLW).
9. The temporary placement or double handling of excavated or till materials within waters
or vegetated wetlands is not authorized.
10. This permit does not authorize the interference with any existing or proposed Federal
project, and the permittee will not be entitled to compensation for damage or injury to the
authorized structure or work which may be caused from existing or future operations undertaken
by the United States in the public interest.
11. No attempt will be made by the permittee to prevent the full and free use by the public
of all navigable waters at or adjacent to the authorized work. Use of the permitted activity must
not interfere with the public's right to free navigation on all navigable waters of the United States.
12, The permittee shall comply with the attached list of United States Coast Guard
Regulations.
13. No excavated or fill material will be placed in any location or in any manner so as to
impair surface water flow into or out of any wetland area.
14. The activity will be conducted in such a manner as to prevent a significant increase in
turbidity outside the area of construction or construction-related discharge. Increases such that
the turbidity in the waterbody is 50 NTU's or less in all rivers not designated as trout waters by
the North Carolina Division of Environmental Management (NCDEM), 25 NTU's or less in all
saltwater classes and in all lakes and reservoirs, and 10 NTU's or less in trout waters, are not
considered significant.
15. This Department of the Army permit does not obviate the need to obtain other Federal,
State or local authorizations required by law.
16. This permit does not authorize interference with any existing or proposed Federal
projects.
17. In issuing this permit, the Federal Government does not assume any liability for:
a. Damages to the permitted project or uses thereof as a result of other permitted or
unpermitted activities or from natural causes.
b. Damages to the permitted project or uses thereof as a result of current or future
Federal activities initiated on behalf of the general public.
c. Damages to other permitted or unpermitted activities or structures caused by the
authorized activity.
d. Design and construction deficiencies associated with the permitted work.
this permit.
Damage claims associated with any future modification, suspension, or revocation of
18. The permittee understands and agrees that, if future operations by the United States require
the removal, relocation, or other alteration, of the structure or work herein authorized, or it, in the
opinion of the Secretary of the Army or his authorized representative, said structure or work shall
cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be
required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural
work or obstructions caused thereby, without expense to the United States. No claim shall be made
against the United States on account of any such removal or alteration.
In addition, the permittee shall notify

9. PROJECT DESCRIPTION
The Town of Ocean Isle Beach is proposing maintenance dredging of six man-made, "natural" canals and
the connecting channels into the Atlantic Intracoastal Waterway. The canals are located between
Causeway Drive and Concord Street on the island of Ocean Isle, Brunswick County. In addition, the
Town proposes maintenance dredging of two entrance channels into the concrete canal system between
Concord and Lee Street (labeled as entrance canal number 8 and 3). These canals were originally
constricted prior to 1978. Previous maintenance dredging permits have been issued for all areas with the
possible exception of the upper end of Canal #21 near the head of Laurinburg Street. This area was
previously separated from the rest of the canal system by a plug. The plug has been mostly removed, but
the connection remains narrow and transitions into a natural shoreline with a marsh fringe on both sides
of the water body. It is unlikely that this area can be dredged to 40' wide without excavating wetlands.
These man-made canals border narrow residential lots developed with single family residences. The
"Commercial Canal", # 22, borders Causeway Drive and various businesses. The canals vary in width
from 80' - 110' (except as noted above on Canal #21). The shorelines along the canals are almost all
stabilized by bulkhead structures. Some lots have Spartina alte iflora marsh between their bulkhead and
the open water. These marsh fringes range in width from 0-20'. No disturbance of these marsh fringes
is proposed.
The applicant is proposing to dredge a channel 40' wide by 6' deep down the center of the canals and out
to the deep water connection to the Atlantic Intracoastal Waterway. A typical cross-section of the
proposed work is shown on Sheet 3 of 5 of the plans. The proposed dredging would be widened to a
flared expansion at the Waterway connection of 80' wide. This 80' flared feature has been requested in
previous applications, but subsequently limited to the 40' width due to potential impacts to shellfish
resources.
An estimate of 16,300 linear feet of canal is to be dredged to a width of 40'. The average existing water
depth is -2.3 at low tide. The applicant is requesting to dredge to a depth of -6' at low tide. The
consulting engineer estimates that there will be 76,000 cubic yards of spoil material to be excavated to
reach the desired -6' low tide depth. The dredging would be accomplished by hydraulic dredge. The
Town has permission to pump the spoil material into an existing diked spoil disposal area accessed off
of the end of Lee Street. The spoil island has been divided into thirds with an earthen dam separating
the western 1/3 that is to be used in this project. This one third portion of the spoil island designated
for use is approximately 6.8 acres in size. See Sheet 3 of 5 of the plans for the location of the disposal
area and Sheet 4 of 5 for the plan view and cross sections. The project engineer has submitted plans for
excavating some of the existing spoil material out of the basin and onto the dam - thereby increasing the
height of the dam while creating more storage room for new spoil. Supporting calculations have been
submitted for review.
The waters of the man-made canals have been classified as SA by the Division of Water Quality. They
are closed to the taking of shellfish and are not a designated Primary Nursery Area. However, the
adjoining waters of the Atlantic Intracoastal Water are open to the taking of shellfish as determined by
the Shellfish Sanitation Section.
TOWN OF OCEAN ISLE BEACH

10. ANTICIPATED EVIPACTS
Approximately 652,000 square feet of shallow bottom would be dredged as a result of this proposal. The
dredging will result in temporary increased turbidity in the project area. Of the 652, 000 square feet to
be dredged, approximately 24,000 square feet has no history of maintenance dredging (although it is a
man-made canal). If the dredging of this 24,000 square feet is allowed, the proposed width may need to
be significantly reduced to lessen impacts to coastal marsh fringes. Provided the work is done in the
Winter during a lower biological activity period, no other long term adverse impacts are expected.
Approximately 296,208 square feet of high ground will be filled for the spoil disposal. Sediment Control
devices will be necessary around the spoil disposal area until disturbed soil on the dam has been stabilized
with vegetation sufficient to restrain erosion.

MAINTENANCE DREDGING 2000 - "NATURAL" CANALS
TOWN OF OCEAN ISLE BEACH
OCEAN ISLE BEACH, NORTH CAROLINA
Background
The small boat access `natural' canals and the entrance canals to the "concrete"
canals which were created in the 1960's are located directly off the AIWW and have
shoaled over the years since their last dredging, especially in the heads of these canals
as well as at the entrance canal where normal traversing tides flow across the mouths of
these canals. These tides have deposited material, thereby resulting in inadequate draft
depths in areas along these canals. It is proposed to accomplish maintenance dredging
in these canals in the approximate footprint of previous CAMA permits.
Project Description
It is proposed to use a hydraulic pipeline dredge to remove spoil from these
"natural' canals and entrance canals as shown on the maps contained in this
application package. All materials excavated will be pumped to the western third of
the existing dredge spoil -disposal island located at the end of Lee Street which was also
utilized during the previous dredging event in 1996. Pipeline corridors willbe
established to ensure that no marsh areas or sensitive vegetation will be crossed in any
} case during the .operation. All dredging will be done during the winter season when
biological life in the surrounding waters willbe at a minimum.
Environmental hnPacts
Since the dredging will be performed during minimal activities of biological life,
it is our belief that environmental.impacts resulting from the dredging activities
proposed in this projectin general will be relatively minimal. Much of the canal
' bottoms to be dredged consist of sand, sediment, and detritus and have been
previously dredged in the past.

material to be placed in the disposal facility is not
contaminated and is compatible with management plans for the
facility. The first step in this process is to submit a grain
size analysis report on the material to be dredged. The results
of the grain size analysis will, in part, determine the need for
any additional chemical testing. At least one composite sample,
consisting of at least five grab samples, shall be taken at each
major shoaling location at the rate of one composite sample per
10,000 cubic yards of material to be dredged. If the project is
maintenance, surface grabs are sufficient. If the project
involves new work, grabs for the composite sample must consist of
full dredging depth cores.
.The grain size analysis consists of a minimum of 6 U. S.
Standard Sieve Sizes (4,10,40,60,100,and 200) with a gradation
plotted for each composite sample (sample included as (Exhibit
3). If the grain size analysis indicates that the average amount
of the samples passing the 1200 sieve (i.e. sediment --ner than
sand) is 10 percent or less, no additional analysis is required.
If greater than 10 percent, an evaluation must be completed to
provide an initial determination of the probability or
contamination of the material to be dredged (Exhibit -^_)
identifies typical considerations. The Grantee will need to
contract with qualifed firms for both the grain size analysis and
the evalutation for the potential contamination.
g. The Grantee shall be responsible for any repairs
required to the dike, spillway and/or spillway effluent pipe
located within the disposal site as a result of its activities.
Repairs shall be completed to the satisfaction of the Wilmington
District.
h.. The Grantee shall make payment to the Finance and
Accounting Officer, U. S. Army Engineer District, Wilmington for
disposal material placed on the licensed premises. Payment at
shall be shade at the current disposal fee rate of $1..50 per cubic
yard. Payment for disposal shall be based on contractor payment
invoices or actual before and after dredge surveys and shall be
made within 30 calendar days of completing dredging operations.
Under certain conditions the disposal fee can be partially offset
or waived entirely. If the dikes or spillway requires
substantial repairs in order for the disposal area to be usable
the Grantee may submit invoices reflecting these costs and
receive credit against the disposal fee. Credit will not be
given for any repairs to the dikes or spillway required as a
result of the Grantees dredging operation. Also, 'if any or all
of the dredged material can be removed within 180 calendar days
of the completion of the dredging operation, credit will be given
at the rate of $1.50 per cubic yard for the amount removed. The

canals :and entrance canals as shown on the attached maps contained in this application package.
All materials excavated will be pumped to the western third of the existing dredge spoil disposal
island located at the end of Lee Street which was also utilized during the previous dredging event
in 1996. Pipeline corridors will be established to ensure that no marsh areas or sensitive
vegetation will be crossed in any case during the operation. All dredging will be done during the
winter season when biological life in the surrounding waters will be at a minimum.
It is our feeling that environmental impacts resulting from the dredging activities
proposed in this project in general will be relatively minimal and since the dredging will be
performed during minimal activities of biological life. Much of the canal bottoms to be dredged
_ consists of sand, sediment and detritus and has been previously dredged in the past

Dear Mr. Dorney:
Reference the application of Town of Ocean Isle Beach for Department of the Army
authorization and a State Water Quality Certification to perform maintenance dredging on
a man-made canal system along with entrance channels off the Intracoastal Waterway in
Ocean Isle Beach, Brunswick 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 Section 10 of the Rivers and Harbors 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.
According to our administrative regulations, 60 days is reasonable for State action.
Therefore, if you have not acted on the request, or asked for an extension of time, by
January 26, 2001, the District Engineer will deem that waiver has occurred.
