8. PROJECT SUMMARY:
The applicant is proposing agitation and water injection maintenance dredging along the northwest
leg, west leg, east leg, Range C, barge berths and fuel docks along Radio Island and the barge berth
areas within Newport River.
9. Narrative Description
The NC State Ports Authority is proposing agitation and water injection maintenance dredging
along the NC State Ports Authority property in Morehead City and along Radio Island.
The Morehead City Land Use Plan classifies this property as Port Mixed Use, with all
AEC's classified Conservation. This section of the Newport River and Morehead City
Channel/Bogue Sound is not designated as Primary Nursery Area and is closed to the taking of
shellfish. Both water bodies carry a water classification of SC. Substrate in the Newport River and
the Morehead City Channel/Bogue Sound area is mostly sand and silt. No SAV's or shellfish beds
were observed within the proposal project area.
10. Proiect Description:
The existing major permit # 51-87 was issued on August 16, 2006, a renewal on August 19, 2013,
a minor modification on 11/10/14, a second renewal on 12/8/15 and is set to expire on December
31, 2017. It authorized upland development and an additional docking facility.
The applicants are asking for a major modification to permit #51-87 for agitation and water
injection maintenance dredging along all portions of the NC State Ports Authority properties. Per
the applicant this is to help maintain the authorized depths of both deep draft -45' +2 (berths 1,2,3
and the east turning basin), shallow draft -35' +2 (berths 4-7, west turning basin, barge fleeting
areas, barge dock) and along the Radio Island aviation fuel terminal to a depth of -38' +2.
11. Anticipated Impacts:
The maintenance excavation within Newport River/MHC Channel/Bogue Sound would
temporarily disturb a total of 10,282,000fft2 of deep draft and shallow draft areas and sand and silt
bottom habitat. The maintenance excavation would not remove any sediment from the system due
to the method of dredging, with the material suspended in the water column. The increases in
suspended sediment and turbidity levels from the dredging will be temporary, occur while the
dredging operation is taking place and should be minimal given the bottom composition.
Maintenance excavation would occur as needed to maintain the operation of these areas as
historically done through the general permit process. Previous employments of agitation method
of dredging in this area has not had any known impacts on resources.

Subject: Port of Morehead City Agitation Maintenance and Water Injection Dredging, CAMA
Major Permit Modification (# 51-87)
Dear Heather Styron,
On behalf of the North Carolina State Ports Authority, Dial Cordy and Associates Inc. is pleased
to submit this CAMA Major Permit modification (# 51-87) to the Division of Coastal Management
for review and permit issuance.
The Port of Morehead City has used agitation maintenance dredging in emergency situations
(CAMA MP #122-04) to supplement the United States Army Corps of Engineers (USACE)
maintenance dredging to prevent the loss of vessel throughput due to sediment accumulation
around its berths. As part of the additional conditions stipulated in DCM CAMA Major Permit
(#122-04), the port is requesting a modification to CAMA Major Permit (# 51-87) to include the
use of agitation maintenance and water injection dredging (also known as scour jet dredging) as
maintenance techniques to be used during the dredge window of August 1St to March 31St during
ebb tides only. The proposed action is part of the long-term maintenance plan to fully maintain
authorized depths and prevent the loss of commerce. The port is also requesting the use of
current and proposed maintenance techniques to maintain the authorized depth of the turning
basins within the inner harbor.
Included with this letter are the following documents for your review and consideration: MP1 and
MP2 forms for the proposed permit modification to CAMA Major Permit (# 51-87). Also available
are the Essential Fish Habitat Assessment (EFH) and Biological Assessment (BA) as requested
by the USACE during the scoping meeting held May 25, 2016. The EFH and BA will be delivered
to the USACE Wilmington District office in paper and disk form. We look forward to working with
you to complete the proposed permit modification.

5. Activities and Impacts
a. Will the project be for commercial, public, or private use? ®Commercial ®Public/Government
❑Private/Community
b. Give a brief description of purpose, use, and daily operations of the project when complete.
The primary purpose and need of the NCSPA is to fully maintain authorized depths of both deep draft -45 +2 ft (Berths 1, 2,
and 3 and the East Turning Basin) and shallow draft -35+2 ft [Berths 4 through 7 and West Turning Basin,Barge Fleeting
areas, Barge Dock (-12 +2 ft) and Aviation Fuel Terminal (-38 +2 ft)] year-round, maximizing vessel tonnage capabilities.
Berths 8 and 9 are used by the US Military and therefore are federally maintained to a depth of -35 +2 ft MLLW. Sediment
accretion within berthing areas results in losses of real and marketable tonnage capabilities and a reduction in a vessel's
benefit/cost financial analysis.
The Port is proposing the use of agitation maintenance dredging techniques [Towing I-beam sled, sweeping I -Beam and
Water Injection (Scour dredging)] as a means to fully maintain congressionally authorized depths. It is expected that these
techniques will be operational only once or twice annually and will follow agency guidelines previously set for agitation
maintenance dredging (AMD) and water injection dredging (WID) at the Port of Wilmington, such as operation during falling
tides only, and any new requirments. The limited spatial area and temporal duration of events, as well as good
engineering/best management practices, minimizes the potential effects of AMD and WID on soft bottom habitat present in
the project areas (please refer to project narrative for a more detailed description of proposed use).
c. 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 stored.
Agitation maintenance dredging promotes natural downstream movement of unconsolidated alluvial material that has
precipitated within the Port of Morehead City's (POMC) berths. If unaddressed, the precipitants will accumulate reducing
authorized working depths. A decrease in authorized working depths will reduce tonnage throughput and operational
economic values. The proposed water injection dredging method utilizes hydrodynamic principles in a cost-effective
approach with reduced environmental impacts compared to conventional dredging techniques such as trailing suction hopper
dredges, cutter head dredges and clamshell dredges. The POMC is proposing to use AMD and WID to fully maintain depths
of their berths, quays, and turning basins to prevent loss of commerce. The WID technique utilizes high volumes of low
pressure water pumped through a series of nozzles on a horizontal jet bar to disrupt the internal friction and cohesive
properties of the sediment to create a fluidized soil layer (density current). This layer of sediment remains close to the
channel bottom and moves out of the project area via gravity driven density current and remains within the hydrologic system
allowing for natural deposition downstream. Like other methods of agitation dredging, the material does not have to be
removed from the system, which serves to reduce typical costs associated with dredging and transporting dredged sediment.
The port is proposing this dredging method as supplemental to the annual dredging performed by the USACE and is
expected to be used 1-2 times annually during environmental dredging windows. Specific reaches that have accumulated
sediment between 6-12 inches will be dredged on an as needed basis reducing the spatial extent per dredging event. The
water injection system will consist of a barge mounted (see project narrative for detailed description) system and will be
moored or dry docked at one of the NCSPA's facilities.

PROJECT NARRATIVE
PROPOSED ACTION
The Proposed Action by the North Carolina State Ports Authority (NCSPA) at the Port of
Morehead City (POMC) is to modify the existing Coastal Area Management Act (CAMA) Major
Permit 51-87 to include agitation maintenance dredging (AMD) and water injection dredging
(WID) within the inner harbor at the POMC (Figure 1). The AMD will be performed by towing an
-beam sled (Figure 2) behind a tug boat. The I-beam agitates the accumulated alluvial material
during an ebbing tide, thus perpetuating the natural downstream sediment cycle. The WID will
be performed from a small barge equipped with a series of hydraulic jets mounted on a boom
that suspends fine sediments into the lower water column where they can travel away from the
project area on an outgoing tide (Figures 3 and 4).
The POMC's inner harbor is divided into four segments: Northwest Leg, West Leg, Range C,
and East Leg. Within these segments are nine berths comprising 5,366 feet (ft.) of wharf
frontage. Additionally, the POMC currently has two berths (The Aviation Fuel Terminal
authorized to 38'+2 and Barge Dock 12'+2') along the eastern side of Range C on Radio Island.
The POMC has both shallow draft and deep draft channels, Berths 1, 2, and 3 have
congressionally authorized depths of 45+2 ft. and Berths 4 through 9 are authorized to 35+2 ft.
The East turning basin has a depth of 45+2 ft. (1,350 ft. diameter) and the West turning basin
has a depth of 35+2 ft. (1,000 ft. diameter). Currently, AMD has only been authorized on a per
event basis (CAMA Major 122-04 Emergency modification) and the Division of Coastal
Management has requested the POMC address shoaling on a long term basis.
Agitation maintenance dredging is accomplished by deploying a large I-beam sled (Figure 2) or
sweeping an I-beam along the bottom, thereby resuspending sediments that have settled along
the berths. When AMD is deployed along the port's berths, it drags material from the berths out
into the channel during an ebb tide cycle continuing the natural sediment process downstream.
This method utilizes simple technology to alleviate the reduced depth due to natural sediment
accumulation. It is typically, deployed behind a tug boat along specific reaches that have shoaled
faster than surrounding areas. During a traditional dredging event, significant costs are incurred
by barging and removing sediment. For this reason, the cost associated with AMD and WID
dredging is reduced significantly and sediments continue along their natural cycle.
Water injection dredging, also known as scour jet dredging, is a relatively new dredging
technique developed 25 years ago. Water injection dredging can be a very efficient dredging
method that utilizes hydrodynamic principles in a cost-effective approach with reduced
environmental impacts compared to conventional dredging techniques such as trailing suction
hopper dredges, cutter head dredges, and clamshell dredges. This technique utilizes high
volumes of low pressure water pumped through a series of nozzles on a horizontal jetbar to
disrupt the internal friction and cohesive properties of the sediment to create a fluidized soil
layer (Figure 3). This layer of sediment remains close to the bottom and moves out of the
project area via gravity -driven density current and remains within the hydrologic system allowing
for natural deposition downstream. Like agitation dredging, the fine material does not have to

be removed from the system, which serves to reduce typical costs associated with dredging and
transporting dredged sediment.
The POMC proposes the techniques of AMD and WID as supplemental to the United States
Army Corps of Engineers' (USACE) maintenance dredging. These techniques will be deployed
on an as needed basis that is expected to occur once or twice per year. The AMD technique of
dragging an I-beam sled has already been deployed successfully, with no deleterious effects to
Essential Fish Habitats (EFHs), through an emergency modification to CAMA Major Permit 122-
04.
Habitat in Action Area
The Newport River Estuary is tripartite in nature consisting of the: (1) Newport river estuary that
extends from the Beaufort Inlet inland to the town of Newport; (2) portion of Bogue sound
extending from Beaufort Inlet west to a point west of Broad Creek near the Intercostal Waterway
Marker 33 and; (3) Back Sound and North River from Beaufort Inlet to a line between "Bottle
Run Point" and Harkers Island. The Newport River Estuary is dominated by semidiurnal tidal
cycle and has a water volume calculated at 168 x 106 m3 (220 x 106 yards3), (Kirby -Smith and
Costlow 1989). Sediments along the outer channel are dominated by course sands from the
middle of Range C to the Beaufort Inlet. Finer grained sediments are found around the POMC's
berths and quays, especially in the Northwest and East Legs, where water flows are reduced
due to depth and tidal hydrology. Finer grained sediments from the upper reaches of the
Newport River eventually settle in these areas of reduced water flow.
As described by Wolf Technologies Inc. (USACE 2008), the POMC sediment composition
varied with sample location around the POMC's berths and quays. The Northwest and East
Legs primarily consisted of silty sands, however a portion of the West Leg and Range C
consisted of poorly sorted course sands. The mean of 25 samples collected from the POMC's
berths, quays, and turning basins revealed 78% (by weight) of material collected from
vibracores passed through a 0.18mm sieve. This data suggests the berths and quays surround
the POMC are compatible for WID. Unlike WID, AMD's efficiency is not restricted to specific
grain sizes and is therefore also compatible with the sediments located within the POMC's
berths, quays, and turning basins.
The primary factors affecting the estuarine benthic community species occurrence, distribution
and abundance includes sediment grain -size and organic content, sediment depositional rates,
dissolved oxygen (DO) and salinity. Alexander et al. (1983) described the infauna community
characteristics in the lower estuary of the Newport River as adaptable to a wide range of
environmental conditions. Sampling of the lower Newport River Estuary was dominated by
polychaetes (48%) and gastropods (28%). Characteristic fauna included Ilyanassa obsolete,
Tagelus spp., Neris falsa, and Amphirite ornate. These species are considered proficient at
recovering from bottom disturbances. Epibenthic species living on the sediment generally
include gastropods, amphipods, and some insect larvae. Other more motile epibenthic species

such as juvenile fish, crabs, and shrimp vertically migrate within the water column on a daily
basis. The general condition of an area is reflected in the benthic community's health; whereas,
the epibenthic community present provides insight on the movement and timing of post -larvae
and juvenile fish species important both commercially and recreationally (Mallin et.al. 2000).
Although no benthic sampling has been conducted directly within the anchorage or berth
locations, it is highly likely that the benthic community includes species commonly preyed upon
by local fish populations. Due to the consistent level of vessel activity and annual dredging at
the NCSPA terminals, the benthic foraging habitat in these areas is probably significantly less
diverse and abundant than downstream of the port, even when considering the rapid rate of
recovery to disturbances by these opportunistic species common to this softbottom habitat.
The South Atlantic Fishery Management Council (SAFMC) has designated several Habitat
Areas of Particular Concern (HAPCs) within North Carolina waters. South Atlantic Area Wide
HAPCs are "state -designated areas of importance to managed species." North Carolina's state -
designated nursery areas, as depicted in Figure 4, are considered HAPC for post larvae/juvenile
and subadult white shrimp (Litopenaeus setiferus) and brown shrimp (Farfantepenaeus
aztecus). North Carolina's tidal inlets, state -designated nursery areas, and submerged aquatic
vegetation (SAV) are considered HAPCs for red drum (Sciaenops ocellatus) [South Atlantic
Region (SAR) 2008]. Due to the location of the POMC along the eastern edge of Bogue Sound
and within the Newport River estuary, the sparse occurrence of SAV in relatively close proximity
to the POMC is a possibility. The most current SAV data from the North Carolina Division of
Marine Fisheries (NCDMF) (17 September 2014) shows the closest SAV being along the fringe
of Brandt Island to the south of the POMC.
Submerged aquatic vegetation, oyster/shell bottoms, and state -designated nursery areas are
considered HAPCs for the snapper -grouper complex. Mud bottoms and riverine habitat are
considered HAPC's for developmental stages of the gray snapper (Lutjanus griseus) post
larvae/juveniles and adults respectively (SAFMC 1998, SAR 2008). There is currently no
Anadromous Fish Spawning Area within proximity of the POMC. The closest anadromous fish
spawning area in relation to the POMC is within the tributaries of the Neuse River (NCDMF
2007), (Figure 5).
The primary conservation measures minimizing potential direct, indirect, and cumulative effects
by AMD and WID within the soft bottom habitats are the proposed supplemental scheduling, the
limited area of proposed dredge use, operational conditions limiting dredging to only during
falling tides, and the specific targeting techniques that will be applied. The proposed use area
will be restricted to the dockside dredging prism adjacent to all berths and to the turning basins.
By scheduling these techniques with a falling tide, unconsolidated sediment is diffused along the
bottom and continues downstream, thereby alleviating the need for multiple agitations of the
same sediment load. The falling tide windows also limit potential benthic effects operationally to
approximately a 12 -hour day. It is expected that these types of AMD/WID will be implemented
one to two times a year. Agitation maintenance dredging and WID operational goals are one to
two days per each of the one to two annual events. The limited spatial area and temporal

duration of events, as well as good engineering/best management practices, minimizes the
potential effects of AMD and WID on soft bottom habitat present in the project areas.
Project Effects
This section includes a discussion of known or probable effects of the proposed agitation
maintenance and water injection dredging on water quality, and the potential direct and
temporal effects on marine resources including macroinvertebrates and managed fish and
shellfish species. A Biological Assessment has been prepared for sturgeon species, as well as
an EFH Assessment. Both are available for agency review and use.
Agitation maintenance dredging and WID could potentially affect the estuarine/riverine water
column and unvegetated mud/sand bottoms present in and adjacent to the berths, quays and
turning basins. A potential temporary effect of AMD would be a tidally dispersed sediment
plume. Dredging -induced far -field dispersion plumes are often controlled by specialized
dredging equipment with managed production rates. Though successful in reducing sediment
plume concentrations, such efforts do not eliminate sediment resuspension. During WID
operations, a fluidized soil layer (density current) is created that remains just above the bed and
flows under combined forces of gravity and pressure difference of surrounding ambient water.
A potential temporary effect would be a tidally dispersed suspended sediment plume from the
water/density-current interface and the density current potentially settling outside the channel
basin. Best management practices, specialized dredging equipment, and dredge -master's
experience help to reduce suspended sediment concentrations above three meters (m) off the
substrate. Though successful in reducing suspended sediment concentrations, such efforts do
not eliminate the potential for sediment resuspension. The sediment plume's movement is
primarily tied to gravitational settling and local horizontal advection effects. The gravitational
settling rates are dependent on both the sediment composition and suspended sediment
concentration. Several 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 vicinity (Bohlen 2002).
Water injection dredging is a relatively new technique, and as such, documented environmental
studies within estuarine environments are extremely limited. Due to the limited studies available
and the similarities to other forms of AMD, environmental studies used to describe the effects of
WID include conventional AMD techniques and WID techniques. Law Engineering and
Environmental Services, Inc. (LAW) implemented 11 water quality monitoring efforts associated
with pre-, during-, and post -AMD events from July 1998 to August 1999. The surface, mid -
column, and bottom water quality sampling for turbidity, DO, and temperature indicated spatial
and temporal variations in the immediate downstream vicinity of an active AMD operation and at
one berth downstream (approximately 800 ft.) of the operation. Turbidity data collected showed
that the re -suspended unconsolidated alluvial material tidally moved along the bottom and did
not migrate into the mid and upper water columns before dispersion within the natural
downstream flow. The monitoring further revealed no substantial changes in temperature or DO
(LAW 1998 and 1999a -f).

Effects of agitation dredging were monitored for six dredge events in the Savannah River during
2000-2001 [Applied Technology and Management (ATM) 2002], which have been summarized
in an EFH assessment prepared for the Georgia Port Authority [MG Associates (MGA) 2011].
Based on field monitoring data for total suspended solids (TSS), I—beam dragging resulted in an
increase in TSS levels no greater than 300 milligrams per liter (mg/1). The worst-case scenario
observed in the Savannah River was TSS levels of only 150 mg/I 2,000 ft downstream from the
dredged area. An analysis of the plume geometry generated by the I-beam dragging showed
that the high levels of TSS (> 300 mg/1) were limited to 1,500 ft downstream of dredging, with
the widest point of the plume being less than 400 ft across (less than 50% of river width), and
the height of the 300 mg/I plume being less than four feet off the bottom (less than 10% of water
depth). Compared to the 2000-2001 actual data collected during the dredge events, the
calculated plume limits are consistent, showing the primary effects limited to within six feet of
the bottom and the high concentration plume cross-section being less than five percent of the
river cross-sectional area. The model results were found to be conservative in that they
overestimated the actual plume size seen during the ATM study. The author concluded that
TSS concentrations generated from I-beam dragging are quite similar to fluctuations in TSS
caused by spring tide events or the passage of large vessels in the channel and generally much
less than can be generated during major storm events. For DO, ATM (2002) did not show a
measurable effect from I-beam dragging that was significantly different from natural variations
occurring in the river. They concluded that agitation dredging does not have a significant
adverse effect on DO.
The USACE published a report within the Engineering Research and Development Center
(ERDC) where Acoustic Doppler Current Profilers (ADCP) were deployed around a WID project
in Michoud Channel, Louisiana. Back -scatter plots from the ADCP indicated that sediment
remained close to the bottom, between 0.91-1.52m (Pollock et al. 2005), adding further benefit
over traditional dredging. Niskin bottle sampling showed a sharp drop in TSS from 193 mg/I at
2.1 m above the channel bed to slightly higher than background levels at 36 mg/I at 5.8m above
the channel bed.
The most productive WID event recorded by the ERDC occurred in the Mississippi River Gulf
Outlet in August 2003. During the dredging, ERDC personnel collected Niskin Bottle samples in
close proximity to the dredge and analyzed them for TSS. The samples showed TSS levels as
high as 384 and 324 mg/I near the bottom on the channel and 26 and 35 mg/I for the mid water
column at the same sample locations (Welp 2003).
The POMC berth depths are maintained in conjunction with the federally authorized Morehead
City Harbor maintenance dredging. Therefore; as stipulated in 15A NCAC 03R .0103 which
delineates the extents of the Newport River's Primary Nursery Areas (PNA), the proposed
Dredge area is not within a NCDMF primary or secondary nursery area and thus outside a
HAPC. Additionally, there are no SAVs or oyster bars within the proposed action areas. The
action area is not within any associated species spawning area as delineated in 15A NCAC 03R
.0115 and 15A NCAC 10C .0603 Anadromous Fish Spawning Areas. The closest delineated
anadromous fish spawning area to the POMC is the Neuse River.

Figure 1 depicts the POMC's proposed dredging footprint along the eleven berths (Berths 1
through 9, Aviation Fuel Terminal and Barge Dock) and the turning basins. The aquaculture
resources/habitat, with potential direct effects from AMD and WID operations, include the
estuarine/riverine water column and the unvegetated mud/sand bottom. Potential indirect
effects are possible within the federal channel's adjacent water column. Neither Morehead City
Harbor nor the beaches of Bogue Banks or Shackleford Banks are located within a designated
PNA (15 NCAC 3B .1405).
The potentially indirectly affected estuarine marshes are immediately across from the northwest
leg in Sugarloaf Island; however, the marsh complex is located behind a sand beach therefore
limiting the potential effects. Brant Island is located south of the POMC and the associated
marsh complex is also buffered from any direct effects by a sand beach face. A small fringing
marsh is located to the west of the POMC along the northeast portion of Radio Island. The
greatest potential indirect effect on tidal marshes would be a tidally migrating sediment
dispersion plume. As the proposed AMD and WID techniques are implemented to continue the
natural downstream movement of the unconsolidated sediment, the deposition of sediment
within the shallow fringing marshes is highly unlikely. Considered HAPCs, the nearest NCDMF
designated PNA is approximately two miles upstream of the east leg behind Morehead City
along Crab Point Bay. Due to the proposed use of AMD/WID techniques during falling tides, the
diffuse nature of the sediment, the estuary's high tidal velocity, and the limited supplemental use
of AMD or WID; sediment accumulation within the downstream wetland fringes is not anticipated
and indirectly effecting upstream PNAs is extremely unlikely.
The AMD and WID techniques may affect the managed invertebrate species using the
estuarine/riverine water column habitat. The water column acts as the transport medium
between the ocean and estuarine/riverine systems. The managed invertebrate species
reproduce offshore during the spring and early summer months and larvae are then carried by
wind and tidal currents into the estuaries. These earlier life stages have the least capability for
avoiding water column disturbances. The adult and juvenile motility would allow for operation
avoidance during late fall migrations. Potential larval effects from turbidity may occur during
AMD and WID operations; however, the minor supplemental use, operational techniques, and
operational areas would minimize the potential for effects during implementation.
Many commercial and/or recreational fish species would be included as associated species.
The project area is adjacent to a spawning area (North River) as delineated in 15A NCAC 03R
.0115 and 15A NCAC 10C .0603 Anadromous Fish Spawning Areas. The North Carolina
Wildlife Resources Commission (NCWRC) and North Carolina Marine Fisheries Commission
(NCMFC) have designated most of the North River as a PNA and secondary nursery area. The
closest PNAs and secondary nursery areas to the POMC are located in the Newport River
(Figure 4). The Atlantic States Marine Fisheries Commission (ASMFC) oversees and manages
many of these commercially and recreationally important anadromous species such as
American shad (A/osa sapidissima), alewife, hickory shad (A. mediocris) and blueback herring
(A. aestivalis) (ASMFC 2012). The above-mentioned species represent the common taxa found
in the epibenthic sampling; however, a total of 74 species or genera representing 34 families
have been collected during studies by Hetler and Chester (1990) in the Beaufort Inlet.

The AMD and WID operation could have potential indirect effects on estuarine/riverine marshes
and PNAs; each providing potential shelter and foraging habitats for the developing shrimp life
stages. Significant turbidity effects from AMD and WID operations on these habitats are not
anticipated. There are no oyster rock habitats within the proposed dredge areas and the
nearest PNA is approximately two miles northwest of the POMC. The closest known SAV is an
isolated patch along the fringe of Brandt Island (approximately 360m south _of the POMC). The
proposed AMD and WID's limited spatial and temporal extents as well as good engineering/best
management practices will continue to minimize the potential for WID effects on managed
invertebrate species near the POMC within the Newport River Estuary.
Agitation maintenance dredging and WID could have potential indirect effects on proximal soft
bottoms, wetland fringes, and downstream water columns each providing potential pathways
and foraging habitats for invertebrates, coastal demersal, costal pelagic, snapper/grouper
juveniles, highly migratory species and associated species. Potential turbidity effects on these
managed species and habitats would not be anticipated. The AMD and WID's minimum
duration and frequency of use, spatial extents, as well as good engineering/best management
practices would- continue to minimize the potential for dredging effects on managed
snapper/grouper species within the Newport River and near the POMC.
The POMC's North Carolina Division of Coastal Management Major Permit #122-04 emergency
modification was issued 24 August 2016 to allow a temporary agitation maintenance event. The
permit enforced certain stipulations for AMD implementation, such as dredging only during ebb
tide and not -to -exceed dredging limits. These conservation stipulations were followed and the
dredging event was successfully concluded without incident. Good engineering practices and
best management practices will be implemented in order to ensure potential fisheries, managed
species, and associated species effects from WID and other AMD activities are minimized to the
greatest extent practicable.
Listed below are conservation measures that will be adhered to, resulting in the avoidance and
minimization of potential EFH, managed species, and associated species effects.
• Proposed AMD and WID use area is within the POMC dockside dredging prism
immediately adjacent to Berths 1 through 9, Radio Island T -head, barge berths, and the
East and West turning basins.
• Proposed operational use will be during falling tides only.
• The proposed use will be restricted to the USACE's environmental window of Aug 1 -
March 31
• Maintenance dredging activities will also be aligned with this window. Dredging that
occurs outside of this window must have prior approval from the USACE and NCDCM in
coordination with the NCDMF and NMFS.
• The frequency of use will be restricted to one to two times, with each event duration
lasting one to two days.

Agitation maintenance dredging and WID could have potential temporary effects on fisheries
habitats, managed species, and associated species within the proposed localized dredging
prism. The potential effects on the estuarine/riverine, water column, and un -vegetated mud
bottoms would be spatially and temporally minimized through continued good operational efforts
and continued agency coordination. There are no SAVs, shellfish, or hardbottom habitat
located within the proposed dredging locations and the nearest NCDMF designated PNA is
approximately two miles upstream.
In 2006 and in 2012, EFH assessments were prepared and accepted by the National Marine
Fisheries Service (NMFS) for the Port of Wilmington for AMD: "NMFS agrees with the NC State
Ports Authority that, as currently utilized, adverse impacts to EFH and associated managed
species from this infrequently used dredging technique are within acceptable limits." The
addition of AMD and WID to the POMC's maintenance dredging techniques will provide the
NCSPA with several methods to address sediment accumulation and maintain fully authorized
depths. When reviewed by the NMFS, the use of AMD and WID techniques will follow
scheduling approved through corroboration with agencies opinions. Due to the proposed
infrequent use, the results of studies conducted in the Cape Fear River and Savannah River,
the limited spatial extents and best management practices; it is unlikely the
managed/associated species will experience any significant adverse effects from the use of
AMD or WID within the estuarine/riverine water column, or unvegetated mud bottom resources
occurring in the action area.
