Please find enclosed a permit modification request of the existing Maintenance Dredge Permit
(NC DWQ No. 2011-0905) for the mooring basin located at the U.S. Coast Guard (USCG)
Sector Field Office Fort Macon in Atlantic Beach, North Carolina. The USCG proposes to
deepen this existing mooring basin in order to accommodate the deeper draft requirements of two
new SENTINEL -class Fast Response Cutters (FRCs). These 154' -long FRCS are scheduled to
arrive in 2019 and will replace two existing 110' Island -Class patrol boats that are currently
moored in this basin. This permit modification request is also being submitted to the Army Corps
of Engineering Wilmington Field Office for their review and modification of their joint -permit
(USAGE Permit No. 2005-00748).
The USCG intends to complete dredging activities during the summer of 2017. We request your
authorization to dredge the mooring basin as described in this letter. If additional information is
required, please contact my representative, Mr. Richard Hylton, at [phone] or by e-mail
at [e-mail].
Sincerely,
CN

Fast Response Cutter Homeporting USCG Atlantic Beach, North Carolina
(Formerly known as: USCG Maintenance Dredge Small Boat Mooring, Atlantic Beach, Carteret Co.)
Fort Macon Creek (WOK 030503, 20-36-16, SA: HQW)
North Carolina DWQ Project #2011 0905
U.S. Army Corps of Engineers Action ID. No. 2005-00748
20 December 2016
Project Scope. The U.S. Coast Guard Sector (USCG) Sector Field Office (SFO) Fort Macon (Atlantic
Beach, North Carolina) intends to deepen its existing mooring basin in order to homeport two SENTINEL -
class Fast Response Cutter (FRC) vessels. The 154' -long FRCs (with a 26' beam), scheduled to arrive
in fiscal year 2019, would replace two existing 110' Island -Class patrol boats (WPBs, with a 21' beam)
currently homeported at Base Fort Macon. The FRCs are substantially larger than the WPBs they would
replace and would require land -side and water -side improvements. Notably, the FRCs draft three feet
more than the vessels currently at berth and therefore require deeper water in the vessel basin.
Proposed Modification. Based on recent discussions between NCDENR and Haskell's environmental
consultant (Johnson, Mirmiran & Thompson, Inc., or "JMT") the USCG proposes to modify the existing
permit (DWQ Project# 2011 0905; USACE Action ID 2005-00748) from an authorized depth in the
mooring basin of -12.0 feet mean low water (MLW) to a new authorized depth of -14.5 feet (MLW), with
1 foot of overdredge (see cross-sections in enclosed sheets). In addition, the USCG wishes to extend
the dredged area to approximately 100 feet to the north where waters are deeper and therefore navigable
for the FRCs (see enclosed sheets). The innermost area of the existing basin is not proposed to be
dredged deeper than its present condition. Dredging would likely be accomplished with a floating crane
equipment barge and a scour barge. A clamshell bucket attached to a crane on the equipment barge
would scoop up sediment from the basin floor and transfer the dredged material to the scour barge until
the desired depth is achieved. Dredged material would be offloaded from the barge to an on-site
dewatering cell developed at a suitable location, dewatered, and trucked to an authorized upland disposal
site, or transported directly to an authorized upland disposal site. The state's coastal program encourages
the disposal of beach quality material onto a beach. It is the Coast Guard policy to test and dispose of
dredge materials at a licensed/appropriate landfill. Additional information regarding sediment testing will
be provided under separate cover, following coordination with state and federal jurisdictions. Preliminary
sample locations for sediments are shown in Figure R-3.2 in the attached set of plans.
Permit Correspondence. Correspondence regarding the permit/action is listed in Table 1 below.

Environmental Assessment. The environmental assessment (EA) noted in the above table describes
the purpose and need for the FRC homeporting and evaluates the environmental effects of alternative
plans for homeporting the FRCs. This EA tiered from the Final Programmatic EIS (PETS) for the Integrated
Deepwater System Project (US Coast Guard 2002), which evaluated the potential environmental effects
associated with acquisition of new assets. USCG signed a Finding of No Significant Impact (FONSI) after
completion and review of the EA in August 2013. Scoping comments submitted to USCG were received
by
• US Army Corps of Engineers;
• US Fish and Wildlife Service;
• North Carolina Department of Administration, State Environmental Review Clearinghouse;
• North Carolina Department of Environment and Natural Resources, Division of Environmental
Assistance and Outreach;
• North Carolina Department of Environment and Natural Resources, Division of Coastal
Management;
• North Carolina State Historic Preservation Office;
• North Carolina Department of Transportation; and
• North Carolina, Division of Emergency Management, Floodplain
Management Program.
The North Carolina Department of Environment and Natural Resources, Division of Coastal Management
(NCDENR DCM) noted only two issues related to natural resources in response to the Draft EA. They
were the following:
Page 2

CWA Permit Modification for USCG Ft Macon
JMT Proposal number 16-1017-001
20 December 2016
1. Identify in EA if dredged material would be of beach quality. The state's coastal program
encourages the disposal of beach quality material onto a beach.
2. Identify if the homeporting of two vessels would have an effect on shellfish closures.
In response to the above, the Final EA indicated that USCG anticipates that based on analysis of
previously dredged material, it would not be suitable for beach disposal (Section 2.5, Alternative 2). The
Final EA also included an analysis (Section 3.7, Water Resources) to indicate that homeporting would
not have an effect on shellfish closures.
Summary of Effects: Water Resources. The EA concluded the following, with regard to potential effects
on water resources in the project area:
1. Construction activities would have temporary, minor, adverse impacts on local water quality.
BMPs and environmental conservation measures would minimize impacts on water quality,
particularly related to erosion control and the control of contaminant release.
2. Land -side actions associated with the project would not add more than 10,000 square feet of new
built upon area and would not disturb more than one acre. In addition, no new impervious surface
would be created, and storm water control would be designed to be equal to, or better than, the
previous development.
3. A permit from the USACE would be required for dredging and would contain terms and conditions
to minimize impacts on water quality.
4. Vessel operation and maintenance would continue to be subject to existing permits, procedures,
and regulations to avoid or minimize adverse water quality impacts.
5. Homeporting would not contribute to the listing of waters as impaired due to a loss of use for
shellfish harvesting.
Summary of Effects: Biological Resources. The EA concluded the following, with regard to potential
effects on biological resources in the project area:
1. The modified project would have no effect on federally listed piping plover, skipper, or sea turtles,
and may effect but is not likely to adversely affect West Indian manatee, shortnose sturgeon, and
Atlantic sturgeon.
2. Potential impacts on NOAA trust resources would occur from dredging and from land -side actions
that have the potential to introduce contaminants or sediment into Bogue Sound. However, BMPs
and environmental conservation measures would be implemented to protect water quality.
Page 3

CWA Permit Modification for USCG Ft Macon
JMT Proposal number 16-1017-001
20 December 2016
3. Dredging could impact NOAA trust resources that live in sandy substrate. These species are
mobile and to varying degrees would be able to escape the dredging. Species would be expected
to recolonize dredged areas.
4. No significant adverse impacts on marine mammals and migratory birds.
At this time, we wish to clarify two items listed above from the EA. First, regarding item 2 above, the word
"may" should replace "would:" we believe that due to the BMPs that will be utilized, any measureable
impact to NOAA trust resources due to contamination and/or sediment would be highly unlikely. Second,
regarding item 3 above, organisms living within the substrates that will be dredged will be impacted, but
populations of benthic infauna are expected to recolonize the area within one to three years. Mobile
species are anticipated to flee the area during construction, and return either following completion of
dredging or as food resources (benthic infauna and epifauna) recolonize the area.
Avoidance and Minimization of Impacts. As previously noted, the mooring basin was dredged in the
fall of 2012 (and subsequently maintenance -dredged) under the aforementioned permits. The terms and
conditions included in the existing Clean Water Action (CWA) Section 404 permit and CWA Section 401
Water Quality Certification will be adhered to, but for the modifications proposed in this letter. The terms
and conditions are included in Section 2.7 of the EA (Best Management Practices and Environmental
Conservation Measures). Those regarding water resources and biological resources are transcribed
below for convenience:
Water Quality. The Coast Guard would comply with storm water pollution prevention plan
requirements, applicable water discharge permit regulations (including 401 Water Quality
Certification), total maximum daily load limits, state and local water resource protection and erosion
reduction measures (including preparation of an erosion and sediment control plan if the project would
disturb one or more acres), and other water quality regulations. Conditions of these plans and permits
would include BMPs such as the following to minimize release of sediments and the subsequent
adverse effects on water quality, wetlands, and waters of the US:
1. Prevent demolition debris and construction materials from falling into Bogue Sound.
2. Cover soil stockpiles and exposed (graded) slopes.
3. Provide permanent ground cover within 15 days following completion of construction.
4. Install and maintain erosion and sedimentation controls between the construction site and
nearby surface waters to prevent an increase in sedimentation or turbidity within waters and
wetlands outside of the permitted area.
5. Use erosion control techniques such as mulching, filter fences, straw bales, or diversion
terracing.
6. Prior to commencing dredging activities, install floating turbidity barriers with weighted skirts
that extend to within one foot of the bottom around all work areas that are in or adjacent to
surface waters. These barriers will stay in place and be maintained until work has been
completed and all erodible materials have been stabilized.
7. If a dewatering system is used, all water collected from the system shall have a turbidity value
less than 25 NTU (Nephelometric Turbidity Units) before being discharged into the mooring
basin. In the event this threshold is exceeded, all operations must cease and appropriate
measures taken to restore conditions to within acceptable water quality standards.
8. Ensure construction equipment is in good repair, without leaks of hydraulic or lubricating fluids,
and use drip pans when vehicles are parked.
Page 4

CWA Permit Modification for USCG Ft Macon 20 December 2016
JMT Proposal number 16-1017-001
9. Perform fueling and maintenance of vehicles off-site or at designated areas with secondary
containment and stocked with spill response sorbent pads and equipment.
10. Develop and approve a hazardous materials control plan prior to construction. The plan would
include the handling, storage, cleanup, and disposal of petroleum products and other
hazardous substances used during construction.
11. Adhere to the Spill Prevention Response Plan and Spill Control and Countermeasures Plan
in the event of contaminant release.
Biological Resources. The following preliminary measures are included in the proposed action to
avoid significant adverse effects on listed species that may occur in the project area:
1. For the protection of anadromous fish, Atlantic and shortnose sturgeon, and the West Indian
manatee, no in -water work would be conducted from February 1 through July 31 of any year.
2. USCG and its contractors would employ the US Fish and Wildlife Service's (USFWS's)
Guidelines for Avoiding Impacts to the West Indian Manatee — Precautionary Measures for
Construction Activities in North Carolina Waters.
3. If construction activities occur during the migratory bird breeding season (spring to early
summer), prior to project implementation a survey would be conducted to determine if there
are any nests of migratory birds within the project area. If one or more nests of migratory birds
are present in the project area, halt construction activities until appropriate mitigation
measures are determined.
Mitigation of Impacts. No mitigation is proposed at this time.
