TPA
The US Coast Guard (USCG) proposes the maintenance dredging of the Walter Slough
navigation channel, which serves as access to USCG Station Oregon Inlet, and the station's'boat
basin, in Pamlico Sound, Dare County, North Carolina.
Enclosed please find a Pre-Construction Notification (PCN) form and a check in the amount of
$570 for the application fee.
Maintenance dredging, conducted on an as-needed basis, is necessary to maintain safe navigation
in the channel. The PCN form requests NC Division of Water Quality authorization for the
discharge of dredged material in:
© Open water at the nearshore disposal area off the north end of Pea Island,
o Open water under the Herbert C Bonner bridge, in existing scour holes around the bridge
supports
o Established control-of-effluent bird islands, initially and primarily Island D but possibly
other approved islands in the future
o Return water from upland confined disposal facilities (none exist at this time but one or
more may be utilized at some time in the future)
o Effluent/runoff from temporary high ground disposal sites, from which dredged material
will be removed to a permanent high ground location.
USCG has prepared an Environmental Assessment (EA) for the proposed project. The EA
identifies and discusses proposed dredging and disposal alternatives. USCG has also provided
an application for an individual permit to the Wilmington District Corps of Engineers Regulatory
Division and a determination that the proposed project is consistent with the North Carolina
Coastal Management Program to the NC Division of Coastal Management.
Thank you for your attention to this matter. Should you have any questions, please contact Mr.
Ray Pipak of my Central Engineering Unit in Cleveland at telephone [phone] or Jeff
Richter of the Wilmington District Corps of Engineers' Environmental Resources section at
telephone [phone].

Page 4 of 15
PCN Form - Version 1.3 December 10, 2008 Version
3e. Describe the overall project in detail, including the type of equipment to be used:
Maintenance dredging on an as-needed basis. Dredging will be conducted by most feasible method of dredging; either
hydraulic pipeline, mechanical (clamshell, dragline, etc), government owned special purpose (small hopper), commercial
or government-owned suction or draghead. Dredging will be conducted during established environmental window
(October 1 to Febraury 14). Method of disposal would be dependent on type of dredge used.
Disposal. Prior to past dredging events, sediments within the proposed project area were sampled. Locations and
results of the borings are attached (Attachment A). The majority of these past dredging events and borings have
indicated that the shoals were composed of sandy material. It appears that more fine-grained material is found in the
USCG basin (northeastern portion of Range 7).
Additional sampling would be conducted periodically to update knowledge of the sediment grain sizes in the areas to be
dredged and to determine appropriate disposal locations.
a) Control-of-Effluent Placement. Control-of-effluent disposal is a methodology involving discharge of dredged material
on an unconfined disposal site located on an island. In North Carolina, this methodology is usually employed for the
discharge of sandy material on sites considered to be nesting habitat for colonial waterbirds.
The dredging is performed by a dredge that conveys the dredged material to the disposal site via pipeline, resulting in a
slurry pumped to a sandy "high point" on the disposal site. The slurry is directed to run down from the high point. The
sandy material drops out, creating an unvegetated sandy dome, which becomes the desired nesting habitat. By the time
the remaining slurry gets to the surrounding waterbody, most if not all the sand has dropped out and only a fraction of the
water enters the waterbody.
Material containing less than 10% fine-grained material ("fine-grained" is defined as being less than 0.0625 mm in size) is
considered acceptable for placement on colonial waterbird nesting habitat.
Island D is the nearest and most appropriate control-of-effluent island. Island D has been used by the Corps numerous
times in the past for the discharge of sandy material dredged from nearby navigation channels. Prior to discharge, the
Corps coordinates with NC Wildlife Resources Commission (NCWRC) regarding the availability of the island for any
particular disposal event and to determine the appropriate location on the island for the discharge. This coordination
would occur for any discharge onto the island from the Walter Slough project.
b) Confined Upland Facility Disposal. Confined upland facility disposal involves the placement of dredged material on a
previously constructed site, enclosed by dikes or other barriers. This disposal method is usually used for non-sandy
material, and is most efficiently performed by a dredge that conveys the dredged material to the disposal site via pipeline.
When a slurry is discharged into the disposal facility, it is retained long enough for sediments to settle out. Water
detention and release are controlled by flashboard risers in the outfall structure. The remaining water contains minimal
suspended sediment and is discharged to the receiving waters in compliance with applicable water quality regulations.
Currently, there are no available confined upland facilities near the project site. One area, located north of the USCG
Station, has been used in the past but is presently unavailable for use. This unavailability will likely continue into the
foreseeable future. If a suitable site becomes available in the future, this method of disposal may be used. A site would
be considered suitable only after all necessary resource agency coordination has occurred and all necessary
authorizations and approvals have been received.
c) Temporary High Ground Placement with Subsequent Removal. This proposed disposal method is most suitable for a
job involving a relatively small amount of material that is excavated by mechanical means, when an offsite final disposal
location has been approved. Once excavated, material is transported to a temporary holding area before being removed
to the final disposal area. The temporary handling area is surrounded by silt fence and hay bales. Material is offloaded
from the dredge, scow, or barge by mechanical means either directly into dump trucks or onto the holding area, then
loaded into trucks and hauled off to a disposal site selected by the hauler. This method has been used for the three
previous Walter Slough maintenance dredge events. Although somewhat inefficient and requiring a good deal of
handling and movement of material, it has been a very effective method of removing shallow shoals when space, time,
and resources are limited and other methods of dredging are not readily available.
At this time, the most suitable temporary holding site is adjacent to the OIFC basin, which, given its proximity to the
portions of the channel that shoal most frequently, is the site most likely to be used for future occurrences of this disposal
alternative. Dare County is the most likely entity tha Yypyl r e dredged material from the site. The OIFC is on Bodie

The dredging history of Walter Slough shows that the earliest documented dredging in Walter Slough was in 1985, when
the USCG removed some 9,400 cubic yards in order to dock their vessels on the north side of Oregon Inlet, because the
channel on the south side had shoaled to the point of being undependable. In 1990, the State of North Carolina paid to
establish a channel for ferry boats, to compensate for the temporary closing of the Herbert C. Bonner Bridge (Highway
NC 12) over Oregon Inlet. In 1994, the USCG, Dare County and the State partnered to dredge Walter Slough. The
USCG contributed heavily to improving the channel into their new $4 million station next to the OIFC. Dare County and
the State jointly financed an emergency dredging job in 1996 to remove about 5,000 cubic yards from Walter Slough
trouble spots for the purpose of providing ferry boat access in the event that the Bonner bridge again became
impassable. In November 1998, Dare County, with financial assistance from the State, paid for the removal of about
19,000 cubic yards of dredged material from shoaled areas of Walter Slough. These emergency dredging operations
occurred as a result of pleas for help from the charter boat captains to Dare County and the State of North Carolina as
there is no formal agreement requiring these or any other government agency to perform maintenance on Walter Slough.
Prior to these efforts, all dredging in Walter Slough was done for either the USCG or North Carolina Department of
Transportation, not to help the charter fishing fleet at the OIFC.
As a result of shoaling impacting USCG navigation in Walter Slough, USCG requested and received a Nationwide Permit
Number (NWP) 35 maintenance dredging permit from the US Army Corps of Engineers Wilmington Regulatory Division
(COE-Reg) on June 20, 2007. The permit authorized the emergency dredging of shoals in the access channel, using
mechanical dredging methodology. The US Army Corps of Engineers Wilmington District (Corps), using the Corps'
debris boat "Snell", successfully completed the dredging work with deposition in the OIFC's parking lot, from where the
sandy material was removed by Dare County trucks. The project was completed in July 2007. Because the OIFC
parking lot is managed by NPS, its use was authorized by a Special Use Permit (SUP) from NPS.
A similar project was conducted in 2009, in response to shoaling in the navigation channel. COE-Reg stated that the
project remained authorized by NWP 35, and in coordination with North Carolina Division of Coastal Management
(NCDCM), the USCG determined that the proposed work was consistent with the North Carolina Coastal Management
Program, submitting a formal consistency determination by letter dated February 17, 2009. By letter dated March 25,
2009, NCDCM concurred with the consistency determination. NPS reissued the SUP. The "Snell" successfully
completed the dredging (temporary disposal in OIFC parking lot, material removed by Dare County trucks) in May 2009.
The same dredging and disposal methodologies were coordinated in 2010, with the project occurring in August and
September.
In February 2011, USCG requested assistance from the Corps in removing shoals in the navigation channel that prohibit
mooring of the USCG "Motor Life Boat" (Vessel specifics: 47-ft long, 4-6' draft) at Station Oregon Inlet. The Corps
determined that use of its special purpose (small shallow draft hopper) dredge "Currituck" with disposal in a scour hole on
the west side of the Herbert C. Bonner Bridge expeditious. Following state and federal resource agency coordination,
the "Currituck" dredged approximately 5,000 cubic yards of sandy material in 6 days, completing the work on March 2,
2011.

6. Future Project Plans
6a. Is this a phased project? ® Yes ? No
6b. If yes, explain.
Maintenance dredging will occur on an as-needed basis within established environmental windows. Any work that must
occur outside established windows will first be fully coordinated with state and federal resource agencies. Each iteration
of the project will be conducted in accordance with processes (dredging and disposal methodologies) identified in the
project description. Any different dredging or disposal methodology will be discussed with state and federal resource
agencies prior to being employed.

4g. Comments: The entire open water area identified will not be impacted each dredging iteration. Because the total amount
of material to be dredged at any one time is expected to be less than 10,000 cubic yards, it is expected that only one disposal
location would be used each time. Because dredging would occur on an as-needed basis, the shoaling rate affecting the
channel will dictate when dredging must occur. It is possible that no dredging may occur in certain years.
