III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no laxger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are

(Note -this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The USCG Station Emerald Isle facility has been in place
since the early 1940s. Basin is a fixed location but access channel follows naturally deep
water. Residential property exists around the Station and private docks have been
constructed into the channel. Shoaling occurs on a routine basis gradually impeding
navigation. Recent survey~August 2007) shows that shoaling in access channel is beginning
to pinch at one or more~oints Beach disposal area is routinely used for disposal of beach
quality material dredged by Corps of Engineers from AIWW and Bowe Inlet Sidecast
dredging performed by Corps of Engineers in adjacent waters (Bogue Inlet) almost every
year in between contracted dred~-inQa projects Nearshore disposal area has not been used in
recent past. DAs 60 and 61 have been used for disposal of dredged material but have not
been used in past 5 years. Recent (May 22 2007) sediment testing shows that material in
basin and channel is beach quality sand (less than 10% fine grained sediments).
10. Describe the overall project in detail, including the type of equipment to be used: On an as-
needed basis over next 10 years USCG will have maim dredging of basin and access channel
performed. Ideally USCG will partner with US Army Corps of Engineers maim hydraulic
pipeline dredging contracts in nearby portions of AIWW and/or Bogue Inlet Disposal from
these would preferably be on existing federal beach disposal are on west end of Emerald Isle
However if material not beach quality sand it would go in a confined upland facility In
situations where hydraulic pipeline dredge can't be contracted work could be done by
mechanical dredge, with disposal in same location. In between contracted dredge events if
shoaling impedes navigation in basin or channel USCG would contract with Corps for use of
govt owned dredge plant either Sidecast or special purpose (small shallow-draft hopper
with disposal in either adiacent waters (Sidecast) or nearshore (~ecial purpose) area in 6-10
feet of water off western end of Emerald Isle.
11. Explain the purpose of the proposed work: Maintain safe navigation in USCG basin and
access channel over next 10 years for~urpose of allowing USCG to execute their mission in
area of responsibility.
1~. Priar Projeci ;F3istory

authorized and maintained channels.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
Proposed project is planned to occur on an as-needed basis over next 10 years. After 10 years,
an extension of the authorization will be requested. Although unlikely, if work outside
advertised scope is necessary, additional authorization would be requested
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Proposed maintenance dyed ing of
basin and access, with preferable discharge of sandy dredged material on an existing beach
disposal area, previously used for the disposal of beach quality material from the the
maintenance Bred ing of the AIWW and Bowe Inlet. In certain circumstances disposal
could occur in adjacent water (sidecast dredge), in nearshore disposal area (mechanical or
special purpose dredgel, or in confined upland facility. If material is not beach quality it
would be placed in confined inland facility. Work would occur on an as-needed basis over
next 10 years, ideally in conjunction with a contracted Corps of Engineers maintenance
dredrin~ project in nearby waters. Quantities to be dredged for each event will be unknown
until just prior to dredging event.
2. individually list wetland impacts. Types of impacts include, 'uut are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

VII. Impact Justification (Avoidance and Minimization)
Expected pond surface area:
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. Project involves maintenance
dredging of existin navigation channels in naturally occurring deep water to the maximum
extent practical and disposal within previously authorized disposal areas and/or using methods
that have been .determined to have minimal and short-lived impacts. No beach disposal will
occur outside the established environmental window of Nov 16 to April 30 unless all resource
a~ency approvals are received
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 January 15, 2002, mitigation will be required when
Updated 11/1/200
Page 10 of 14

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 NCEEP 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.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.
No mitigation will be constructed as the project involves maintenance dredging and disposal
of dredged material in previouslyused areas and/or using methods that have been determined
to have minimal and short-lived impacts. To the maximum extent practical, work will occur
during times of low biological activity, and sandy material will be returned to the ocean front
shoreline.
2. Mitigation may also. be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP

Project involves maintenance dredging of an existing navigation channel and basin for use by
€ISCG. Private docks presently constructed in channel. Little if any room for add' 1 docks, but
proposed basin and channel maintenance in itself would not encourage any new construction
XV_ Wither Circumstances (optional}:
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
Proposed project is presently not included in upcoming contracted maintenance dredging_project
scheduled for winter 2007. However Auk 2007 survey shows shoaling is creating several pinch
points in access channel. By letter dated September 21, 2007, USCG requested emer ency
permit authorization to side-cast dredge these shoals in late Fall -early Winter 2007.
