9. PROJECT DESCRIPTION
The project site is located at 1002 South Front Steet, adjacent to the Cape Fear River, in Wilmington, New Hanover
County. To locate the property from the Wilmington DCM Office, travel north on Cardinal Dr. Ext. and turn left on to
Market St. Drive 0.4 miles and turn right on to Martin Luther King Jr. Parkway (US -74W). Travel 5.5 miles and then
continue on to N 3rd St., staying on N. 3rd St. for 1.5 miles. Take a left turn on to Castle St., and after 0.2 miles turn left
on to S. Front St. Continue 0.4 miles down S. Front St. and Colonial Terminals, Inc. will be on the right-hand side of
the road. The project is located on the east bank of the Cape Fear River, just south of the Cape Fear Memorial Bridge
and is approximately 38.6 acres, averaging approximately 6' above normal high water (NHW). The site has been
utilized for commercial berthing operations since the early 1970's to unload and store petroleum products. Existing
structures include: office buildings, timber pier, liquid bulk storage containers, load -out towers, and railway. The
application states the material comes in on freight tankers and is unloaded at the existing dock via pipeline. From there,
the material would be fed into the storage containers then transported to the load -out tower where it is deposited into
trucks and/or railcars for off-site transportation.
The existing shipping pier, measuring approximately 280' in length by 7' in width, which terminates onto a "T -head"
platform measuring approximately 586' in length by 7' in width. The existing facility extends to the US Army Corps of
Engineers (USACE) Wilmington Harbor Line. State Permit No. 106-74 was originally issued to Union Oil Co. —
Chemical Division on June 26, 1974 for excavation of a berthing area at their terminal site along the Cape Fear River,
which was then transferred to Colonial Terminals, Inc. (JLM Terminals, Inc.) on February 17, 1993. State Permit No.
106-74 was modified on October 29, 2002 to allow for expansion of the authorized berth area (-900' in length by 50'
in width) to -38' below MLW. State Permit No. 106-74 was renewed on April 5, 2007 and was due to expire on
February 28, 2012. State Permit No. 106-74 was last renewed and modified on September 19, 2012 for an increased
excavation depth to -42' + 2' overdredge allowance @ MLW. State Permit No. 106-74 is subject to Session Law 2009-
406, and as amended by Session Law 2010-177, the Permit Extension Act, and is now scheduled to expire on
December 31, 2016.
Upland vegetation consists of wild grasses and hardwood species located on the western portion of the site. Existing
coastal wetlands on the site includes a border of Smooth Cordgrass (Spartina alterniora), Phragmites, Spike Grass
(Distichlis spicata), Saltmeadow Cordgrass (Spartina patens), and Groundsel Tree (Baccharis halimifolia) that is
approximately 30 ft. in width and 2000 ft. in length.
The waters of the Cape Fear River (in the vicinity of the project) are classified SC, by the N.C. Division of Water
Resources. The area is designated as a Primary Nursery Area (PNA), by the N.C. Division of Marine Fisheries and
these waters are CLOSED to the harvesting of shellfish. The City of Wilmington Land Use Plan classifies the area as
Conservation.
PROPOSED PROJECT
The applicant is proposing a major modification to State Permit #106-74 to incorporate the use of agitation dredging to
maintain an existing shipping berth within the Cape Fear River. The agitation dredging proposed is similar to what is
currently authorized to the NCSPA (State Permit No.47-87): mechanical agitation via a sled or sweeping beam towed
by a tug or similar vessel. The applicant states that the sled and the beam method would utilize a similar type sled used
in the Savanna Georgia harbor and in over 50% of Wilmington's deep water berths on the Cape Fear River. The
proposed sled is a triangular shape and constructed with steel beams (See photograph of sled on Page A2 of 7 of the
Project Narrative). The proposed sled would have a 15 to 20 foot base and a 15 to 20 foot height frame, with a total
weight of approximately 5,000 lbs., and 1 to 2 inch diameter rods attached to the beams would aid in the agitation of
the deposited sediments. The applicant intends for the sled to be pulled by a tug or work boat using a cable. The
application states that these units have been shown to be effective in maintaining berths with widths greater than 100'
to the edge of the shipping channel.

Colonial Terminals, Inc. (Philip Watts) c/o Gary Greene Engineering
Page Three
As stated, the existing berth is approximately 900' in length by 50' in width. The application states that material would
be re -suspended back into the river system during an ebb tide with the proposed agitation dredging methods. The
shoaling rate within this segment of the river is such that accelerated maintenance dredging has been necessary in order
that the applicant and other facilities along this segment of the river to avoid a potential safety hazard for grounding of
vessels on the shoaling area while attempting to unload within this berth. It should be noted that the NC DCM along
with other state and federal resource agencies receive maintenance excavation requests from the NCSPA on an annual
basis to address the dangerous accelerated shoaling within their berths. The applicant states that over 50% of the
Wilmington Harbor deep water berths are currently authorized for agitation dredging using mechanical or hydraulic
methods. (See Sheets A3 of 7).
10. ANTICIPATED IMPACTS
Excavation within the existing berth along this segment of the Cape Fear River would result in material re -suspended
back into the river system through mechanical agitation dredging. The same method was evaluated for The NCSPA
(State Permit No.47-87), which is located downstream from the project site. State Permit No. 47-87 was issued to the
applicant via a variance through the Coastal Resources Commission (CRC). This proposal does not differ in concept
from the method authorized under State Permit No. 47-87. In effect, the agitation dredging would sweep accumulating
fines from the berth area to avoid the creation of shoaled areas, which could result in unsafe terminal operations. Based
on information presented by the agent and information on agitation dredging in use in other facilities within this
segment of the river, it is anticipated that there would not be adverse impacts associated with the operation of this
system. The potential for short term sediment suspension impacts is certainly much more acceptable than the
possibility of product loss due to vessel damage resulting from grounding.
The application also states that biological monitoring and study reports were compiled by Law Engineering in 1998 for
facilities such as the NCSPA. The application states that the monitoring was done before, during and after the dredging
events. Based on the results of the reports, the data indicated that "dredging apparently caused no significant affect on
temperature", "The peak turbidity values measured during and after dredging do not indicate a correlation to dredging
activity", "Dredging appears to have no significant impact on dissolved oxygen at the depths and locations sampled",
and "the scope and analytical sampling procedures, and analytical parameters are adequate to measure the water
impacts of agitation dredging". The applicant also references the Biological Assessment for Short Nose and Atlantic
Sturgeons Port of Wilmington and other Private Terminals prepared by Dial Cordy and Associates in 2014, which
reported similar results for mechanical dredging at the Port of Wilmington and the Petroleum Fuel and Terminals
berths.

EXISTING CONDITIONS OF PERMIT:
Colonial received permit 106-74 in May 1992 for transfer of the permit from JLM Terminals to Colonial
with the following stipulations associated with dredging.
1) This minor modification authorizes the expansion of the existing berthing area to the following dimensions:
900 feet long by 50 feet wide by 38 feet deep.
2) In order to protect juvenile shrimp and finfish populations, no dredging will be permitted between February
15 and May 31 of any year without prior approval of the Division of Coastal Management, in consultation with
the Division of Marine Fisheries.
3) All excavated materials will be confined on high ground above mean high water and landward of regularly
or irregularly flooded marsh behind adequate dikes or other retaining structures to prevent spillover of solids into
any marsh or surrounding waters.
4) The disposal area effluent will be contained by pipe, trough, or similar device to a point beyond the mean low
water level to prevent gully erosion and unnecessary siltation.
5) The terminal end of the pipeline will be positioned at or greater than 50 feet from any part of the dike and a
maximum distance from spillways to allow adequate settlement of suspended sediments.
6) A water control structure will be installed at the intake end of the effluent pipe to assure compliance with
water quality standards.
7) No excavated or fill material will be placed at any time in any vegetated wetlands or surrounding waters of
the state.
8) Excavation will not exceed 38 feet below the mean low water level. In no case shall the depth of excavation
exceed the depth of connecting waters.
9) The activity will be conducted in such a manner s 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 25 NTUs
or less in all saltwater classes are not considered significant.
12) The spoil disposal areas shall be inspected and approved by a representative of the Division of Coastal
Management prior to the commencement of any dredging activities.
The permit was renewed and modified on September 19, 2012 with the modification increasing authorized
excavation depth to -44 feet (42' depth of excavation with a 2' overdredge allowance). The expiration of the
permit is December 31, 2016.
The area to be dredged along with the location of the Corps of Engineers Eagle Island disposal site is
identified in the attached permit drawings P1 and P2.

PROPOSED MODIFICATION TO PERMIT:
The requested modification is to add an option to the permit which would authorize the use of agitation
dredging techniques utilizing mechanical agitation via a sled or sweeping beam towed by a tug or similar
vessel.
Below are two photographs which illustrate equipment typically used for mechanical agitation. On the
left is a sled that is utilized in the Savannah Georgia harbor (similar equipment used in Wilmington NC
harbor). The sled is pulled by a tug or work boat using a cable as shown, or similar for connection. The
illustrated sled is typical, of most used, which is a triangular shape and constructed with steel beams /
shapes. Some sleds will add 1 to 2 inch diameter rods attached to the beams to aid the agitation of the
deposited sediments. Typical dimensions for the triangular shaped sled are a 15 to 20 feet base and a 15
to 20 feet height providing a total weight of approximately 5000 lbs.
The photograph on the right is a barge outfitted with pulleys and winches for dragging a beam with the
barge towed by a tug or work boat vessel. Both the sled and the beam would be lowered into the water
at the berth and pulled along the length of the berth at the mud line during ebb tides re -suspending the
sediments.

ENVIRONMENTAL IMPACTS FROM THE PROPOSED MODIFICATION:
With mechanical agitation dredging methods currently employed near the proposed site and at other
harbors in southeastern United States, the potential impact at the Colonial site will be based on these other
sites noting the locations that are permitted and the studies / data from these sites .
Permitted Agitation Dredging Locations
Agitation dredging utilizing mechanical methods are currently permitted at locations in the Wilmington,
NC and Savannah Ga harbors.
In the Wilmington harbor, a summary of deep water berths (maintained dredge depth > 32 feet MLW)
is noted below along with length of berth and length currently permitted for agitation dredging method.
The lengths for the berths were obtained from the Corps of Engineers'�(t�t�Center's "Port
Facility Spreadsheet" supplemented by permit data for the Surry6�rtYe sland terminals.

Narrative for Colonial Terminals Inc's Proposed
Maintenance Dredge Permit Modification
Summing the lengths, over 50% of the
Wilmington harbor deep water berths are
currently permitted for mechanical agitation
dredging. It should be noted that no dredging
companies are based in Wilmington with
equipment suitable for dredging the above
berths.
In Savannah, over 28,000 feet of deep water
berths have utilized agitation dredging via
mechanical methods. Similar to Wilmington,
there are no dredging companies with
equipment suitable for dredging the deep
water berths.

Similarities of Proposed Site to Existed Permitted Sites
In the Wilmington harbor, the Colonial site is similar to the permitted sites as follows:
• Site is on the Cape Fear River with similar channel and berth project design depths as the
permitted sites at the NC State Port, Buckeye and Altamar berths which are less than 1/2
nautical mile of the site;
• site experiences similar channel currents, tidal fluctuations, water quality and vessel traffic
at the permitted sites at the NC State Port, Buckeye and Altamar berths;
• site has been dredged with sediments deposited on Corps of Engineers' Eagle Island disposal
site similar to the permitted sites at the NC State Port, Buckeye and Altamar berths with
sediment testing to verify suitability of the sediments; and
• site experiences similar sedimentation rates as the permitted sites at the NC State Port,
Buckeye and Altamar berths.
Other similarities to be noted are:
• Site is located on a river located in excess of 10 nautical miles from the ocean similar to the
permitted sites located in both the Wilmington and Savannah harbors; and
• site is located in a harbor where no dredging companies with equipment suitable for dredging
the deep water berths are based similar to the permitted sites located in both the Wilmington
and Savannah harbors.
Data on Environmental Impact of Proposed Action
Monitoring and studies of the other sites have been performed as follows:
1) Agitation Sled Dredging Water Quality Assessment Port of Wilmington (NCSPA), Law
Engineering, 1998'. This report was prepared for the North Carolina State Ports Authority
permit approval for agitation dredging at the Wilmington terminal berths with monitoring
during July 1998 before, during and after dredging. In the Results / Conclusions section
of the report, Law notes a) "...dredging apparently caused no significant affect on water
temperature"; b) "The peak turbidity values measured during and after dredging do not
indicate a correlation to dredging activity"; c) "Dredgi�=JM0421j-

analytical sampling procedures, and analytical parameters are adequate to measure the water
impacts of agitation dredging".
2) Savannah Harbor Agitation Dredging Agitation Environmental Study, EMC 1993 2. This
study was performed to develop information on the environmental status of the Savannah
Harbor as it pertains to agitation dredging. The study included the analysis of sediment and
water samples for contaminants; analysis of fish tissue for bio -accumulation of
contaminants; bioassays to determine lethal effects of re -suspended sediment on organisms;
monitoring two dredging events to determine dissolved oxygen and other instantaneous
effects of dredging; and assessment of the cumulative impacts of dredging.
Monitoring during the two dredging events included the dredged site and a control site in
a slip away from the dredging site. Monitoring results indicated that the control site
consistently exhibited the higher values for metals. The bioassay tests exposed sheepshead
minnows to various concentrations of the effluent collected from turbidity plumes collected
during an agitation dredging event; and the report concluded that water from the plume
exhibited no toxicity.
With regards to turbidity, the report noted the following: "The effects of agitation dredging
on turbidity were most evident in near bottom samples. Turbidity is naturally higher near
the bottom for the following reasons: fresh, less turbid, water lies over more saline water
which traps silt and clay particles. Differential settling of silt and clay particles allows them
to accumulate near the bottom. Bottom resuspension of silt and clay particles also occurs
making bottom waters more turbid. However, as currents increase, turbidity levels increase
throughout the water column. Plumes of turbidity were not constant or consistent which
indicates that the plumes of high turbidity dissipated quickly through dilution by
surrounding less turbid water." With regard to DO, the report noted .."During both
dredging events, dissolved oxygen (DO) levels decreased as turbidity increased. However,
DO levels were never recorded below 3.0 mg/1. This level is not considered to be
threatening to marine life."
The report at the end of the `Conclusions' section stated .."Continuation of agitation
dredging will not result in long-term deleterious impacts."
3) Agitation Dredge Evaluation, Savannah Harbor Ecosystem Restoration Project, 2002 3.
With approximately 15 permits for agitation dredging in the Savannah harbor, the Savannah
District of the US Army Corps of Engineers developed a scope of work in 1989 to assess
the potential effects of agitation dredging. The three major components of the study were
a) determine aquatic resources in the river at risk from the effects of agitation dredging and
conduct a literature review of published effects levels on these resources; b) conduct field
studies to determine the level of temperature, DO, salinity, turbidity and selected chemical
parameters associated with the `plume' produced by agitation dredging including relative
effects in comparison the background levels; and c) determine the potential for effects on
the identified aquatic resources from observed effects produced by agitation dredging
events.

Contract work included the firms of Dial Cordy and ATM with continuous monitoring
equipment deployed in May 2000. Field reconnaissance work began in July 2000 along
with data collection in the fall of 2000 and spring of 2001. After receiving comments to
draft reports, a final report was submitted to the Savannah District in June 2002. In section
10.2 `Conclusions' of the report, the following was noted.
- "While short-term water column effects of elevated TSS concentrations have been identified by
this and previous studies, no unacceptable adverse effects have been identified by this study as
a result of agitation dredging."
- "Water quality profiles taken down river sometimes indicate that agitation dredge operations
create a near field and brief DO depression.... DO depressions downstream of agitation dredge
operations were equal to or DO concentrations were similar to concentrations observed in
background profiles."
- "The conclusion, therefore, is that dissolved oxygen depression or increase, while observed in
some cases, is not a significant effect of agitation dredging generally."
- "Considering the duration of exposure, season, life stage, volume of water body and percent of
suitable aquatic affected, there is not convincing evidence that agitation dredging activity as it
is performed in the Savannah Harbor creates unacceptable adverse impacts on aquatic
resources."
4) Impact of dredging including agitation methods on Shortnose and Atlantic Sturgeons for
Port of Wilmington and Other Private Marine Terminals, January 2014 4. A study that
included essential fish habitat impact and biological assessment of maintenance dredging
was performed for the NC State Port and private terminals including the Petroleum Fuel &
Terminal berth. The report concluded the following:
Maintenance dredging either through use of a hydraulic cutterhead dredge, clamshell or with
Ibeam dragging will result in elevated TSS and turbidity levels for a short duration ranging from
10 to 15 days for hydraulic or clamshell to less than a day or so for I-beam dragged at each
terminal. Due to the small footprint during I-beam dragging and because of tidal effects and the
dynamic nature of sediment plumes, a single location in the water column will not be affected
by a plume for more than a few hours. Dredging is not expected to result in depressed DO levels
during dredging most of the year, other than during the late summer/early fall when water
temperatures are higher and DO lower (Mallin 2013). Dissolved oxygen levels during the 1999
monitoring of agitation dredging at the POW were not depressed and did not go below 5 mg/1
or show any correlation to temperature or turbidity (NCDENR 2009 and LAW 1999).
Maintaining the anadromous fish in -water construction moratorium from February 1 through
September 30 of each year helps ensure that the potential summer DO sag is not further
depressed by dredging and thereby adversely affecting the behavior or health of sturgeon.
In March 2014, the National Marine Fisheries Service (NMFS) accepted the report and
recommended that operations be performed on falling tide, be 5000 feet apart for
simultaneous events and no agitation outside dredging window without roval from
NMFS. pECE1V

Summarizing the above, reports and monitoring of agitation dredging via mechanical methods indicate
that no adverse impacts are expected. Note that these agitation operations have continued for a
minimum of fifteen years in Wilmington without any reported incidents nor the requirement for
additional studies nor monitoring. In Savannah, subsequent reviews by the Georgia Environmental
Protection Division regarding agitation has resulted in determinations to continue the agitation
operations.
Based on the above, agitation dredging as proposed for the Colonial Terminals Inc terminal is not
expected to result in any adverse impacts.
Proposed Frequency
As noted below, typical deposition rates are approximately 1 foot in the first months. With this
deposition rate, it is desirable to perform agitation dredging on a frequency of six to eight weeks
depending on actual deposition incurred. The reasoning for this frequency is for the following:
• minimizing impact on available ship draft at the berth;
• minimizing the duration required of agitation dredging to achieve desired depth; and
• minimizing the consolidation of the sediments to aid in re -suspension of same.
It is acknowledged that any agitation dredging should not occur during spawning and other critical
habitat periods in the river; therefore, restrictions for dredging during segments of the year would
necessitate coordination with and prior approval from the Division of Coastal Management, through
the Division of Marine Fisheries using parameters such as, but limited to, current and forecasted water
temperatures.
JUSTIFICATION:
The berth at the Colonial terminal in Wilmington experiences shoaling sufficient to hinder the operation
of the terminal due to lack of available draft. In the initial months, the rate of deposition is as much as one
foot per month (based on bathymetric monitoring) followed by a reduced rate in the latter months. The
justification for allowance of agitation dredging is based on availability of equipment to economically
dredge the berth at desired frequencies and economic impact due to lack of sufficient vessel draft at the
berth.
With no equipment based in the Wilmington harbor, deep water terminals rely on dredging equipment
being available in the harbor only when the Corps of Engineers performs maintenance dredging of the
adjacent federal channels. The Corp of Engineers does make efforts to coordinate with the terminals
concerning dredging; however, scheduling can be beyond both the Corps and dredge contractor's control.
This can result in long periods between dredging activities at the berth. For example, the dredge may be
available to dredge the berth at the beginning of the Corps' contract one year. But on the following year,
it may not be available until after the Corps' contract. This can result in as much as 16 months between
dredging events at the berth. With a 16 month period, the berth may only have an available draft of less
than 34 feet mean low water which impacts the ability to schedule ships to call the terminal.
With the limited number of dredging companies that can perform deepwater dre~ the amount of
dredging performed annually in the United States, the availability of ic&&v4W#,CeTf�,c laze to the
Wilmington harbor is limited and most often none would be available. In order tomoh}ze a dredge to

Narrative for Colonial Terminals Inc's Proposed Colonial Terminals Inc,
Maintenance Dredge Permit Modification Wilmington, NC
the site from it's home base, Charleston SC would the least distance. The time to travel to the site and
travel back to the operations base would be a total of eight days at a cost of $1,600,000 5. Considering the
total yardage of dredged material is typically less than 10,000 cubic yards, the mobilization cost (would
have to add three to four days for set up and removal of pipe) per yard would be prohibitive to dredge
outside of a Corps of Engineers contract if a dredge were available.
Unlike liquid bulk and most general cargo where ships call at multiple ports of call at both origin and
destination countries / regions, vessels in the dry bulk trades will typically call on only one port at cargo
origin and destination. Also, ships are chartered for these trades in advance and are expected to carry a
set tonnage. Therefore, it is necessary for berths utilized for dry bulk cargoes to provide the noted draft
provided in port directories. An loss of one foot of draft can result in a loss of up to 2000 tons of cargo
capacity for the ship. Considering the value of most dry bulk cargoes, it is necessary for shippers to
utilize the largest ship capacity possible. Therefore, the loss of vessel draft capability at the berth can
result in shippers directing cargo to other terminals creating significant economic impact to the terminal.
SUMMARY:
The typical shoaling rates at the Colonial berth combined with the limited availability of dredging
equipment, in the Wilmington harbor, to provide maintenance dredging impacts the terminal operations.
In order to maintain available draft at the berth, modification of the permit to authorize agitation dredging
utilizing mechanical methods is requested. These agitation methods have been employed at other nearby
and southeastern locations. Previous studies / monitoring at these locations, which are similar to Colonial,
indicate that allowing agitation dredging at the Colonial Inc terminal is not expected to result in any
adverse impacts.
Anticipated and requested frequency for agitation dredging at the berth would be every six to eight weeks.
This requested frequency recognizes that any agitation dredging should not occur during spawning and
other critical habitat periods in the river. Therefore, restrictions for dredging will necessitate coordination
with and prior approval from the Division of Coastal Management, through the Division of Marine
Fisheries for set periods annually.
