AEC HAZARD NOTICE
Project Is In An: X_ Ocean Erodlble Area --High Hazard Flood Area --Inlet Hazard Area
Applicant: — Dare
Property Address: —Oregon Inlet, Dare County
Date Lot Was Platted: —NlA—
This notice is intended to make you, the applicant, aware of the
special risks and conditions associated with developmentin this
area, which is subject to natural hazards such as storms, erosion
and currents. The rules of the Coastal Resources Commission
require thatyou receive EmA PC HazardNotice and acknowledge
that notice in writing before a permit for development dan be
issued.
The Commission's rules on building standards, oceanfront
setbacks and dune altetations are designed to minimize, but not
eliminate, property loss from hazards. By granting permits, the
Coastal Resources Commission does not guarantee the safety of
the development and assumes no liability for future damage to
the development. Permits issued in the Ocean lfazard Area of
Environmental Concern include the condition that structuresbe
relocated or dismantledifthey become imminently threatened by
changes in shoreline configuration. The structure(s) must be
relocated or dismantled within two (2) years of becoming
imminently threatened, and in any case upon its collapse or
subsidence.
The best available information, as accepted by the Coastal
Resources Commission, indicates that the annual long-term
average ocean erosion rate for the adjacent property is
_ 2-a6.5_ feet per year.
The rate was established by careful analysis of aerial photographs
of the coastline taken over the past 50 years.
Studies also indicate that the shoreline could move as much as
—5-80___. feet landward in a major storm.
The flood waters in a major storm are predicted to be about
—12—feet deep in this area.
Preferred oceanfront protection measures arebeach nourishment
and relocation of threatened structures. Hard erosion control
struchnes such as bulkheads, seawalls, revetments, groins, jetties
and breakwaters are prohibited. Temporary sand bags may be
authorized under certa'ruconditions.
The applicant mustacknowledge this information andrequuements
by signing this notice in the space below. Without the proper
signature, the licaH will not be complete.
Applicant Signature IDate
SPECIAL NOTE: This hazard notice is required for development
in aroassobject tosuddea and massivestorms and erosion. Permits
issued for development in thisarea expire on December 31 ofthe
third year following lire year in which the permit was issued.
Shortly before work begins on the project site, the Local Permit
Officer must be contacted to determine the vegetation line and
setback distance at your site. If the property has seen little change
since the timeofpermit issuance, and the proposed development
can still meet the setback requirement, the LPO will inform you
that you may begin work. Substantial progress on -the project
must be made within 60 days of this setback determination, or
the setback must be remeasured. Also, the occurrence ofamajor
shoreline change as the result of a storm within the 60-day period
will necessitate remeasurement of the setback. It is important
thatyou checkwith the LPO before the permit expires forofficial
approval to continue the work after the permit has expired.
Generally, if foundation pilings have been placed and substantial
progress is continuing, permit renewal can be authorizei. It is
unlawful to continueworkafter porrnit expiration.

2.1.1 5b. Give a brief description of purpose, use, and daily operations of the project when
complete.
Dredging is necessary to maintain safe and reliable transportation routes through waterways.
Oregon Inlet is no exception. Despite considerable efforts on the part of the USACE, State, and
Dare County, shoaling continues to impede mariners and has resulted in the U.S. Coast Guard's
inability to properly position navigation buoys within the channel. As a result, the risk of damage
to vessels and injury to people continues. Since the 1960's, over 25 people have died and 22 boats
have been lost within the inlet (Dare County, 2018).
Oregon Inlet is considered one of the most commercially vital shallow draft inlets along coastal
North Carolina (Dumas, 2014). Numerous business sectors rely on the ability to safely navigate
this waterway on a regular basis. As such, maintaining safe navigation from Pamlico Sound to the
Atlantic Ocean via Oregon Inlet is critical for the local, regional, and state's economy.
Between 1995 and 2012, the US Army Corps of Engineers, State of North Carolina, and Dare
County have spent an average of approximately $6.25 million per year on dredging Oregon Inlet.
The economic impact of Oregon Inlet to Dare County, however, is very significant and far
outweighs the historic costs necessary to keep the inlet passable via dredging (Dumas et al, 2014).
A recent economic study of the inlet suggested that under recent conditions (when the inlet is
navigable —40% of the time), five business sectors (commercial fishing, seafood
packing/processing, boat building and support services, recreational fishing, and tournament
fishing) contribute an economic impact of $403.5 million in revenues while supporting 3,319 jobs
in Dare County. When incorporating nearby counties including Dare, Currituck, Camden,
Pasquotank, Perquimans, Tyrell, and Hyde, the regional economic impact of the inlet amounts to
$423.3 million while supporting 3,601 jobs. At a larger scale, the study cites an overall statewide
economic impact of $548.4 million and 4,348 jobs. If the inlet were to be navigable 85-100% of
the time over the course of a year, the 2014 study stated that these business sectors could potentially
provide a total annual economic impact of 5,120 jobs and $642.2 million to Dare County, 5,590
jobs and $678.4 million to the region, and 5,397 jobs and $693.0 million to the state of North
Carolina (Dumas et al, 2014).
The economic impact of Oregon Inlet to Dare County prompted the County to partner with the
North Carolina Division of Water Resources (NC DWR) to provide supplemental funding for
Oregon Inlet starting in 2016. The annual report prepared by the NC DWR, which was required
by SL 2013-360, Section 14.22, indicates a Dare County contribution of $884,000 matched with
$1,768,000 by the State to contribute an additional $2,625,000 to the USACE for Oregon Inlet
maintenance in FY 16/17.

Even with the state and Dare County taking initiatives to provide the necessary supplemental
funding to maintain the Oregon Inlet Channel, dredge plant availability has become the primary
reason for not being able to maintain dependable navigation through the inlet. The USACE
Wilmington District dredge plants are in high demand to maintain navigation channels throughout
the East and Gulf Coast including other channels throughout North Carolina. Demand has
increased recently given the ability of other communities to provide supplemental funding for
USACE dredges to conduct navigation maintenance in channels vital to their communities.
Recognizing the need for greater dredging capacity, Senate Bill 99 of Session 2017 was passed by
the North Carolina Senate and provides for the construction of a Public -Private Partnership (PPP)
dredge that can be utilized to maintain shallow draft navigations channels within the state including
Oregon Inlet. Section 13.7(a-h) of the bill states:
... the maintenance of the state's shallow draft navigation channels in a manner that keeps
those channels navigable and safe and minimizes their closure or degradation is a vital
public purpose and proper governmental function and that declines in federal funding and
dredging activity have significantly and adversely impacted the ability of the federal
government to maintain these channels in a timely manner. The resulting deterioration in
these channels damages the significant portion of the economy of the State's coastal
regions that is dependent on the use of the navigation channels by watercraft. Therefore,
it is the policy of the State to support and, when necessary to meet the public purposes set
forth in this subsection, to supplement federal maintenance of the navigational channels.
The bill authorized the allocation of up to $15 million of State funds to be provided, in the form
of a forgivable loan to a private partner for the construction and operation of a dredge capable of
maintaining shallow draft navigation channels throughout the state. The legislation further
authorized the Oregon Inlet Task Force to solicit proposals through an RFP, through which a
private partner could be selected. Proposals were solicited from interested companies and the
Oregon Inlet Task Force selected a private partner to work with. However, prior to significant
investments being made by the dredge partner for planning, design, and construction of a dredge
plant, it is necessary to have permits in place for the maintenance work for which the dredge is
being constructed.
In 2018, Dare County sought to obtain the permits and authorizations required to utilize the PPP
dredge to supplement the USACE's efforts to maintain safe navigation within the confines of
Oregon Inlet and certain connecting channels on a year-round basis. The need of this action was
to maintain the county's, region's, and state's economic viability while preserving environmental
quality and human safety. The specific areas to be dredged under the County's permits included
the same locations as defined in the USACE authorization:
"...a 14 feet deep by 400 feet wide channel through Oregon Inlet and the ocean bar. An
approximate 16, 050 foot -long portion of the channel from Oregon Inlet to Hell's Gate (12-

feet deep by 100 feet wide) and an approximate 2,850 foot -long portion of Old House
Channel (12 feet deep by 100 feet wide) in Dare County" (USACE, 2004).
Given that the channel through Oregon Inlet and the ocean bar as well as the channel from Oregon
Inlet to Hell's Gate are both maintained to follow "best water" and are not in a fixed position, a
channel corridor was defined by the County in which maintenance dredging would be performed
such that it would align with the channel parameters stated above. The nearshore disposal sites
proposed by Dare County for use by the PPP dredge were similar to what the USACE was
previously authorized. Specifically, these disposal areas included the nearshore disposal off the
north end of Pea Island and in deep scour holes around the remaining portion of the Herbert C.
Bonner Bridge.

2.1.2 5c. Describe the proposed construction methodology, types of construction equipment
to be used during construction, the number of each type of equipment and where it is to be

Dredging will be performed on a year-round basis by a newly constructed privately owned hopper
dredge. As stated below in the response to item 6a, the dredge will be outfitted with a number of
specifications that will minimize the risk of impacts to a number of threatened or endangered
species that may be present during dredge operations. This Major Permit Modification includes
the request for operating the PPP dredge for sidecast dredging. Sidecast dredging by the PPP
dredge would be limited for use in areas where the PPP is unable to operate as a special purpose
dredge due to shoaled in conditions. As such, sidecast dredging would be used solely for the
establishment of a pilot channel of sufficient depth for the PPP to then operate as a special purpose
dredge.Sidecast dredging will only occur outside of the fisheries moratorium of April 1 through
July 31. As such, dredged material will be disposed via sidecasting, at the nearshore disposal
location off Pea Island, and/or along the bridge pilings at the remaining portions of the original
Bonner Bridge. No equipment will be stored on the land. When not in use, the dredge will be
docked at a marina or moored in proximity to Oregon Inlet.
2.1.3 6a. Project Narrative
In 2019, Dare County was issued a CAMA Major Permit to utilize the PPP dredge in the same
manner and under the similar conditions as what is currently authorized for USACE to perform
maintenance dredging within the waters in proximity to Oregon Inlet, as defined in the 2004
FONSI. The dredging conducted by the privately owned dredge would not replace dredging
performed by the USACE dredge fleet; rather it would complement the USACE's existing efforts.
Scoyin2 and Consultation History
An interagency scoping meeting convened on September 25, 2018 to discuss the County's initial
proposal to obtain permits to operate the PPP dredge within confines of the channels associated
with Oregon Inlet. During the meeting, it was determined that a CAMA Major Permit, NC DWR
General Water Quality Certificate, and NC State Historic Preservation Office's (SHPO)
concurrence would be required. In addition, from the federal side, a Department of Army (DA)
Individual Permit complying with Section 10 of the Rivers and Harbors Act and Section 404 of
the Clean Water Act would be required. Concurrences would also be needed from USFWS and
NMFS to comply with Section 7 of the Endangered Species Act (ESA) and the Magnuson -Stevens
Fishery Conservation and Management Act. Furthermore, an Environmental Assessment (EA)
would be required to satisfy the requirements of the National Environmental Policy Act (NEPA).
A subsequent meeting was convened on October 29, 2018 between the County and representatives
of Wilmington District's Civil Works and Regulatory Division to discuss the procedural aspects
of the proposed project and to ensure that the actions associated with the proposed project will
strictly adhere to the conditions set forth for the authorized federal project.

Permit applications were subsequently submitted to DCM, USACE, and the NPS. The USACE
and NPS also received the associated EA entitled " Oregon Inlet Channel Maintenance Utilizing a
New Privately Owned Hopper Dredge" (Appendix A) in January 2019. On June 24, 2019, the
Division of Coastal Management (DCM) issued a CAMA Major Permit to the County for the use
of the PPP dredge. Along with CAMA Major Permit #49-19, the County received additional
permits and authorizations to allow for this action including an Individual Permit from the
Department of Army (#SAW-2019-0175) on April 20, 2020, 401 Water Quality Certificate
#20190264 issued by the North Carolina Division of Water Resources on April 26, 2019, and
National Park Service (NPS) FONSI and Special Use Permit #USA20-9500-008.
On March 1, 2021, a second interagency scoping meeting was held to discuss additional actions
the County was considering for which permit modifications may have been requested. These
various actions that were being considered to improve the County's ability to maintain the
navigability within the channels in proximity to Oregon Inlet included increasing the allowable
depth of the ocean bar channel, widening the channel that parallels the Marc Basnight bridge, allow
for the use of sidecast dredging, and utilize the contract dredge Atchafalaya during times when the
PPP dredge is unavailable. After receiving feedback from the meeting attendees and a subsequent
conversations with the USACE and NPS held on March 8, 2021, the County decided to only pursue
permit modifications for two of the additional actions being considered; namely the use of side -
cast dredging under specific conditions to excavate a pilot channel in order for the dredge to
operate as a special purpose (hopper dredge) and to expand the authorized dredging within the
Oregon Inlet ocean bar channel east of Basnight Bridge to a depth of minus 14 feet plus 2 feet,
which is within the authorized depth of the federal project. Details of these two proposed permit
modifications and their anticipated environmental impacts are provided in the following sections.
A pre -filing notification was submitted to the Division of Water Resources (DWR) on July 1, 2021.
As described above, two scoping meetings attended by DWR were held on September 25, 2020
and March 2, 2021 in regards to this project. The project proponent hereby certifies that all
information contained herein is true, accurate, and complete to the best of my knowledge and
belief. The project proponent hereby requests that the certifying authority review and take action
on this CWA 401 certification request within the applicable reasonable period of time.
Proiect Description
The dimensions of the channels in which maintenance dredging was permitted for followed the
USACE authorization, which was defined in a 2004 FONSI as "... a 14-feet deep by 400-feet wide
channel through Oregon Inlet and the ocean bar. An approximate 16,050-foot-long portion of the
channel from Oregon Inlet to Hell's Gate (12-feet deep by 100-feet wide) and an approximate
2,850-foot-long portion of Old House Channel (12-feet deep by 100-feet wide) in Dare
County". Because the USACE authorization allows for the maintenance dredging following best
water, the footprints of the areas to be dredged are not fixed. Rather, a bathymetric survey is
performed prior to each dredge event in an effort to determine the location of the best water for
the channel. As such, for this proposed project, a "dredge corridor" was developed and will serve
as the domain in which dredging could be performed in the future (Figure 1).

In order operate in the most efficient manner and to meet the County's stated purpose and need of
maintaining the economic viability of the county, region, and state while preserving environmental
quality and human safety, the County is seeking the ability to use the PPP dredge to maintain a
depth of -14 ft. MLW + 2 ft of overdepth within the ocean bar channel (currently permitted to -14
ft. MLW) and perform sidecast dredging to excavate pilot channels. Both actions are described in
detail below.
Increasing the permissible dredging depth within the ocean bar channel:
The County's permit currently allows for the Oregon Inlet ocean bar channel to be dredged to -14
ft MLLW without any allowable overdepth. This area is defined as the channel extending east
from the Basnight Bridge out through the inlet past the ocean bar. In 2002, a FONSI issued by the
Coastal Protection Engineering of North Carolina

USACE entitled "Manteo (Shallowbag) Bay Project Maintenance of Oregon Inlet Bar Channel,
Channel Widener" allowed for the USACE Navigation dredge fleet to increase the dredging depth
from -14 ft MLW to an "allowable overdepth dredging to 17 ft MLW". Figure 3 shows a cross
section depicting the increase depth, as shown in the 2002 FONSI. Keeping with the spirit of
having the ability to maintain this channel in the same manner as the USACE, the County requests
the ability to dredge to -14 ft MLLW with 2 ft allowable overdepth. Though the federal
authorization allows for dredging to a depth of -14 ft. MLLW + 3 ft. allowable overdepth, the
County is limiting the request to -14 ft. MLLW + 2 ft. of allowable overdepth due to Section §
143-215.73F of the North Carolina General Statute, which defines a "shallow draft navigation
channel" as a waterway with a maximum depth of 16 ft.

Perform sidecast dredging by the PPP dredge:
The USACE has historically relied upon the use of their fleet of special purpose dredges and sidecast dredges
to assist with the channel maintenance in the project area. Since 1973, sidecast dredges Merritt, Schweizer,
and Fry, have operated within the inlet complex. These dredges often cut a pilot channel through the shoaled
portions of the channels to allow special purpose dredges or larger contract hopper dredges, which require
deeper water, to work in the inlet channel. For example, the USACE special purpose dredge Murden requires
a depth of 4'3" when empty and 8'6"when loaded. The Currituck, the USACE's other special purpose dredge
used to maintain Oregon Inlet, requires 3'4" when empty and 76" when loaded. Therefore, a sidecaster dredge
is sometimes used to dredge a pilot channel allowing the special purpose dredge to more efficiently operate.
As stated in the USACE's 1992 FONSI "Maintenance Dredging and Dredged Material Disposal Plan- Oregon
Inlet and Vicinity", sidecast dredging is typically limited to the removal of isolated shoals when operating in
the channels west of Oregon Inlet. The 2004 FONSI issued by the USACE entitled "Use of Government Plant
to Dredge in Federally Authorized Navigation Projects in North Carolina" states that sidecast dredging is
authorized for the ocean bar channel as well as the channel connecting Oregon Inlet to Old House Channel.
At the time of the initial permit request, the PPP dredge was still in the conceptual design phase. However,
since that time, the design has been completed and the dredge is being constructed with the capability of
conducting sidecast dredging as well as operating as a special purpose dredge. The County is requesting a
permit modification that would allow the PPP dredge to perform sidecast dredging in the same locations as
described within the 2004 USACE FONSI: the ocean bar channel, the channel connecting Oregon Inlet to Old
House Channel and Range 1 within Old House Channel (Figure 1). Sidecast dredging by the PPP dredge
would be limited for use in areas where the PPP is unable to operate as a special purpose dredge due to shoaled
in conditions. As such, sidecast dredging would be used solely for the establishment of a pilot channel of
sufficient depth for the PPP to then operate as a special purpose dredge. Because the dredge is currently under
construction and therefore has not operated as a special purpose dredge, it's precise depth requirements are not
yet known. Recognizing the fact that the new dredge's design is similar to the USACE's existing special
purpose dredge fleet, the proposed action will limit sidecast dredging to cut a pilot channels into "hotspots"
where shoals have reduced channel depths to less than 8'. Figure 3 depicts a hypothetical location where the
PPP dredge could operate as a sidecast dredge within the navigation channel just west of the Basnight Bridge
based on a bathymetric survey conducted by the USACE on June 15, 2015. This figure is provided as an
example of how the proposed action might be implemented based on current conditions. In addition, the
County agrees not to conduct these sidecast activities between April 1 and July 31 without notification to the
DCM and Corps of Engineers Regulatory Division in coordination with the appropriate resource agencies.

Environmental Consequences of the Prouosed Actions
The environmental consequences associated with increasing the dredging depth within the ocean bar channel
and allowing for the PPP dredge to perform sidecast dredging to excavate pilot channels are described below.
Increasing the permissible dredging depth within the ocean bar channel:
Increasing the permissible maximum channel maintenance depth from -14 ft MLLW to -14 ft MLLW with 2
ft allowable overdepth is not anticipated to cause any additional environmental consequences. The 2002
USACE FONSI entitled "Manteo (Shallowbag) Bay Project Maintenance of Oregon Inlet Bar Channel,
Channel Widener" evaluated the environmental consequences of the proposed actions within the document
(including increasing the authorized depth from -14 ft MLW to -17 ft MLW) and did not identify any
environmental concerns associated with the increased depth within that document. It should also be noted that
in 1970, Congress authorized the dual jetties project at Oregon Inlet which included an increase of the depth
of the ocean bar navigation channel from 14 feet to 20 feet. On September 21, 2001, the Corps issued
Supplement No. 2 General Design Memorandum (GDM) and Final Supplement III Environmental Impact
Statement (EIS) which stated that the dual jetties and the 20-foot navigation channel are economically justified
and environmentally acceptable (although the jetty project was never constructed and the 20' channel was
never dredged).

Today, despite regular maintenance dredging within the channel to the east of the Basnight Bridge by the
USAGE, reliable long-term navigability remains a challenge due to shifting sediments and constant shoaling.
This shoaling is attributed to sediment transport through and around the inlet complex. The position and
alignment of the ocean bar channel has been documented to be unstable within the shoal complex (Cleary and
Marden, 2004). Due to the fluctuation of sediment transport rates and the shortness of the channel compared
to the width of the ebb shoals, the channel's position and orientation change frequently. Furthermore, changes
in the volume of the ebb -tidal delta appear to be cyclical and are related to the numerous storms that affect this
area. Wave data gathered by the USACE's Wave Information Studies program from WIS Station 63223,
located offshore from Oregon Inlet, indicates that significant wave heights at Oregon Inlet average about 3 feet
with yearly extreme significant wave heights of at least 10 feet. Wave heights exceeding 5 feet occur
approximately 10% of the time in the project area.
Because tidal inlet systems, including Oregon Inlet, are subject to continuous morphological changes under
the action of tides, waves and transported sediments, any benthic organisms that reside in this dynamic
environment must be quite resilient. As such, the constituents of softbottom communities change with natural
shifting patterns of sediment erosion or deposition (Street et al., 2005). Regardless of the dredging depth,
dredging material from the Ocean Bar Channel will cause an immediate removal of infaunal and non -motile
epibenthic organisms from the softbottom community. However, the dredged areas would be anticipated to
repopulate rapidly as benthic organisms are transported back with migrating sediments. Increasing the
permissible dredging depth from -14 ft MLLW to -14 ft MLLW with 2 ft allowable overdepth would not be
expected to impact benthic organisms.
Federally threatened and endangered species that may occur in proximity to Oregon Inlet are presented in
Table 1. The proposed increase in dredging depth within the ocean bar channel would not be expected to
impact any of these species.

Perform sidecast dredging by the PPP dredge to excavate pilot channels:
Sidecast dredging within the channels in proximity to Oregon Inlet has been performed for decades by the
USACE. The impacts of this action have been assessed in several Biological Assessments, Biological
Opinions, and Environmental Assessments including:
• 1998 USACE Biological Assessment (BA): "Use of Sidecast Dredges Frv. Merritt. Schweizer. and the
Split -Hull Dredge Currituck in Coastal United States Waters "
This BA evaluated the use of the sidecast dredges Fry, Merritt and Schweizer, and the split hull
hopper dredge Currituck that are used throughout the United States' east coast to maintain adequate
depths in navigation channels through shallow draft coastal inlets. The BA analyzed potential impacts
associated with the proposed action on listed species under the NMFS purview that may be in the
project area. The BA concluded that the continued use of the USACE sidecast dredge vessels to maintain
shallow draft coastal inlets along the eastern seaboard on a year-round basis was not likely to adversely
affect any listed species.
• 1999 NMFS Biological Opinion (BO): "Use of Sidecast Dredges Frv. Merritt. Schweizer. and the
Split -Hull Dredge Currituck in Coastal United States Waters "
Based on the consideration of the best available information, the NMFS concluded that the
year-round operation of the hopper dredge Currituck and the sidecast dredges Fry, Merritt and
Schweizer to maintain coastal inlets on the eastern seaboard of the United States may affect, but is not
likely to adversely affect the continued existence of listed species under NMFS purview.
• 2004 EA: "Use of Government Plant to Dredge in Federally Authorized Navigation Proiects in North
Carolina "
This EA addressed the proposed use of government owned dredge plant that included the Merritt or
Fry or similar sidecast dredge and the Currituck or similar special purpose dredge to dredge small and/or
isolated, regularly occurring shoals in federally authorized navigation projects within the USACE,
Wilmington District in North Carolina. Because the intent of the action was to remove shoals
expeditiously that have rapidly developed, the proposed dredging could occur at any time of the year.

• 2004 FONSI: "Use of Government Plant to Dredge in Federally Authorized Navigation Projects in
North Carolina"
Agency and public coordination of the EA resulted in the following project commitments,
facts and conclusions leading to the Finding of No Significant Impact:
• No biological moratoria are proposed.
• The proposed activities are entirely comparable to, and fall within, the scope of past activities
and effects that have been previously extensively analyzed by NMFS. The March 9, 1999
ESA consultation included with the EA concluded that dredging of small North Carolina inlet
channels and navigation channel with the USACE dredge plant would be unlikely to
adversely affect ESA -listed species under NMFS purview. In addition, no new species that are
likely to occur in the action area have been listed or critical habitat designated that would alter
NMFS's previous conclusions.
• The impact summary for the proposed actions stated that the proposed actions would not
cause any significant adverse impacts to Essential Fish Habitat (EFH), Habitat Areas of
Particular Concern (HPAC), or EFH species. Impacts that do occur would be expected to be
minor, temporary, and only short lived on an individual and cumulative effects basis.
• Based on information provided in the EA, USFWS concurred that the project as described in
the EA was not likely to adversely affect any federally listed endangered or threatened
species, their formally designated critical habitat, or species currently proposed for federal
listing under the ESA.
Potential environmental impacts associated with sidecast dredging are primarily associated with increases in
turbidity and sedimentation due to the resuspension of the dredged material. While minor turbidity through the
resuspension of sediments in the water column would be anticipated to occur, turbidity levels during sidecast
dredging may exceed the State standard of 25 Nephelometric Turbidity Units only in the immediate vicinity
of the discharge slurry. Turbidities in the area of any discharges are expected to return to ambient levels shortly
after cessation of dredging activities. Suspended sediment in the water column can block available light for
photosynthesis and therefore reduce the benthic primary productivity by submerged aquatic vegetation (SAV).
The magnitude of the impact depends somewhat on the temporal length of the dredging/discharge activity.
Furthermore, the suspended sediment is not expected to remain suspended in the water column given the
characteristics of the material being dredged and discharged. SAV resources are located in proximity to the
project area (Figure 4), however, no sidecast dredging would occur directly within any sea grass beds. In
addition, in order to reduce potential impacts, when possible, the use of a sidecast dredge will include
positioning of the discharge pipe into the deepest water. Conditions that would preclude this would be if winds
and/or currents would redeposit this material back into the recently dredged area. The decision as to whether
this positioning can be done will be left up to the dredge captain, but the need to avoid deposition in shallow
water to the maximum extent practicable will be emphasized each time a sidecast dredge is used.

Several typical estuarine dredging projects have shown sediment -settling rates ranging from
centimeters/second to meters/second resulting in settlement primarily within the dredge site's immediate area
(Bohlen, 2002). The relatively large grain sizes within the plume settle more rapidly. Coarse sand (>2
millimeters) and gravel settle almost immediately, often with a distance of less than 50 meters from the dredger
(Challinor, 2000). Because of the sandy nature of the material and the locations in which disposal would occur,
elevated turbidity levels would be expected to quickly dissipate and minimize impacts to nearby SAV
resources.
Scientific data are very limited with regard to the effects of sidecasted material on fishery resources. These
effects may be similar, on a smaller scale, to the effects of storms; storm effects may include increased turbidity
and sediment load in the water column and, in some cases, changes in fish community structure (Hackney et
al., 1996). However, like with any dredge, entrainment of fisheries resources by a sidecast dredge is also a
consideration. The NC Division of Marine Fisheries (DMF) recommends a moratorium on dredging during
time periods that are critical to fisheries resources. In particular, it has been recognized that a large portion of
the project area is within a Blue Crab Spawning Sanctuary (Figure 5). Because it is recognized that blue crabs
and other important fishery resources utilize the inlet complex for spawning activities during the summer
months, a moratorium on sidecast dredging will be imposed between April 1 and July 31 to minimize impacts
to these resources.
The federally threatened and endangered species that may occur in proximity to Oregon Inlet as presented in
Table 1 would not be expected to be impacted by the use of sidecast dredging by the PPP within the
channels.

Impacts to Cultural Resources
Dredging has occurred extensively within Oregon Inlet and its connecting channels by the USACE since the
project was originally authorized in 1950. As such, this repeated dredging activity would have disturbed,
damaged, or destroyed shipwreck resources unless scour associated with inlet movement re -deposited vessel
remains at depths below the limits of dredging. The 2008 US Department of Transportation Environmental
Impact Statement (EIS), drafted to support the Bonner Bridge replacement effort, concluded "The North
Carolina Office of State Archaeology site files contain no record of terrestrial or submerged cultural resources
in the Bonner Bridge project area and the associated APE". In addition, the 1991 USACE archeological survey
performed during investigations regarding the proposed dual jetties project in Oregon Inlet revealed the
presence of no historically important resources as well. Therefore, no cultural resources are anticipated to
impacted by the proposed actions of deepening the ocean bar channel or utilizing the PPP dredge for sidecast
dredging.

9. PROJECT DESCRIPTION:
Oregon Inlet is located between Bodie Island to the north, which is part of Cape Hatteras National
Seashore, and Pea Island National Wildlife Refuge, which is located south of the inlet in Dare County.
While primarily undeveloped, a former U.S. Coast Guard Station is located on Pea Island. The building is
listed on the National Register of Historic Places. Oregon Inlet Fishing Center is located immediately
north of the project vicinity on the sound side of Bodie Island and Oregon Inlet Campground is located on
the south end of the island to the east of the Fishing Center. The Basnight Bridge spans the inlet
connecting the two islands via NC Highway 12.Oregon Inlet is a highly trafficked means of access
between the Atlantic Ocean and Pamlico Sound, both by commercial and recreational vessels. The current
bridge has constrained navigation from the ocean to sound and the inlet's interior channels through a
primary navigation span measuring 130' in width. The inlet is currently maintained by the U.S. Army
Corps of Engineers (USACE) Wilmington District via special purpose hopper and sidecast dredges, as
authorized under the Corps' 2004 Finding of No Significant Impact (FONSI) and DCM Federal
Consistency Determination DCM 2004-0061. This authorization allows for year-round dredging at
Oregon Inlet. Since 2016, Dare County and the State of NC (through the Division of Water Resources)
have contributed supplemental funding to the USACE for maintenance of the inlet. However, concerns
regarding continued federal dredge plant availability led to the allocation of $15 million from the State's
Shallow Draft Navigation Channel Dredging and Aquatic Weed Fund to be provided to Dare County as a
local partner for the purchase of a privately -owned hopper dredge for maintenance of the shallow draft
navigation channels and permits to be issued for Dare County to conduct dredging assuming the same
conditions as the federal authorization. State CAMA/Dredge & Fill Permit No. 49-19 was issued to Dare
County on June 24, 2019, The USACE permit (SAW-2019-0175) was issued on April 20, 2020 and the
NC Division of Water Resources issued the 401 Water Quality Certification on April 26, 2019 (Project #
2019 0264).
The project boundaries extend from the Ocean Bar Inlet Channel to Hells Gate Channel to Old House
Channel. While channels lengths and locations vary due to the federal channel authorization following
deep water rather than a fixed location, Oregon Inlet and the ocean bar was previously authorized to a
maximum width of 400 feet and a depth of -14' MLLW. The channel from Oregon Inlet to Hell's Gate is
referenced in the federal authorization as approximately 16,050 feet in length, 100' in width, and dredged
to a depth of -12' MLLW. Old House Channel Range I is authorized at 100' wide and at a depth of -12'
MLLW, and at 2,850 feet in length. Due to the fluctuation in the location of deep water over the years,
federal dredging of Old House Channel expanded from Range 1 to include Range 2 and Manteo Channel
Range 17 Extension; however only Range 1 was included in the County's permit authorization. Dredging
in the inlet and connecting channels was authorized to be conducted by hopper dredge meeting federal
dredge plant specifications, with dredged material disposal at a 5000' length near -shore area south of
Oregon Inlet and adjacent to the north end of Pea Island, or in deep scour holes beneath the remaining
portion of the Herbert C. Bonner Bridge, as needed. Historically, the USACE has dredged the project area
at Oregon Inlet frequently in an effort to maintain navigation.
The waters of Oregon Inlet and Old House Channel fall within the Pasquotank River Basin, as classified
by the NC Division of Water Resources (DWR). The waters adjacent to Oregon Inlet are classified as SA
by the DWR. The NC Marine Fisheries Commission has NOT designated the area to be impacted as a
Primary Nursery Area, and the area is open to the harvesting of shellfish.

Dare County Oregon Inlet Channel Maintenance Project- Major Mod 49-19
Page Three
PROPOSED PROJECT:
An interagency scoping meeting was held on March 1, 2021 to discuss the proposed actions. At that time,
the applicant was proposing to deepen the ocean bar channel, add the use of sidecast dredging, and was
also considering channel widening and a proposal to allow the use of an additional (private) special use
dredge plant. In response to agency feedback and subsequent discussions with the USAGE, the applicant
has eliminated channel widening and the use of the other dredge plant and is now proposing to increase
the depth of the ocean bar channel through the addition of a 2' overdepth allowance and also allow for the
limited use of a sidecast dredging in all authorized channels.
As proposed, the modification would allow for an increase in ocean bar channel excavation to a depth of
-14' MLLW +2' overdredge allowance. The applicant states this is in beeping with the USACE's
authorization to dredge the ocean bar channel to -14' MLLW with a 3' overdredge allowance, and they
are reducing the proposed overdredge allowance to 2' to conform with the state's definition of a shallow
draft navigation channel (see p. 14 of Narrative). Use of the sidecast dredge would be limited to the
shallower shoaled areas having channel depths Iess than 8' where a pilot channel is needed to
accommodate the special purpose hopper dredge's deeper draft. The applicant has also committed to a
moratorium of April I through July 31 for sidecast dredging to minimize impacts to fisheries resources,
unless otherwise coordinated with the USACE and DCM, in consultation with the appropriate resource
agencies.
Otherwise, all other project specifications remain unchanged.
10. ANTICIPATED IMPACTS
The proposed changes would not increase the previously authorized areas to be impacted, but the first
project was originally projected to result in impacts to up to 167 acres of submerged bottom. Up to 287
acres of nearshore disposal site was originally identified as potentially impacted, as well as an
unquantified area at the remaining Bonner Bridge bents in cases of scour holes. However, it should still
be noted that actual impacts will be dependent on future conditions at time of work and are subject to vary
due to the location of the deep water channel. All channels widths remain unchanged, as do excavation
depths for Hells Gate and Old House Range I Channels. Increasing channel depth is not expected to result
in any significant impacts. The sidecast dredging would result in temporary increases in turbidity. The
applicant has stated that every effort would be made to discharge dredged material into deeper water,
when possible. The moratorium between April I and July 31 for sidecast dredging is also intended to
minimize potential impacts to fisheries resources.
