Hi guys,
I'm sorry, I'm not sure which of you handles this- but I just realized you weren't copied on it and I'm not sure if your
project works folks coordinate with you directly or not. Our state resources agencies were okay with it (WRC and DMF)-
just wanted to make sure you were aware and didn't have any questions or concerns with them conducting this event in
a couple weeks.

in 15A NCAC 04B 0124, Design Standards in Sensitive Watersheds.
3. No Sediment and Erosion Control Measures in Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters.
Exceptions to this condition require application submittal to and written approval by the
Division. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, then design and placement of temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands, stream beds, or banks,
adjacent to or upstream and downstream of the above structures. All sediment and erosion
control devices shall be removed and the natural grade restored within two (2) months of the
date that the Division of Land Resources (DLR) or locally delegated program has released
the specific area within the project.
4 Construction Stormwater Permit NCG010000
An NPDES Construction Stormwater Permit is required for construction projects that disturb
one (1) or more acres of land. This Permit allows stormwater to be discharged during land
disturbing construction activities as stipulated in the conditions of the permit. If your project
is covered by this permit, full compliance with permit conditions including the erosion &
sedimentation control plan, inspections and maintenance, self -monitoring, record keeping
and reporting requirements is required. A copy of the general permit (NCG010000),
inspection log sheets, and other information may be found at
http://portal.ncdenr.o[qlweb/wq/ws/su/n dessw#tab-w.
The North Carolina Department of Transportation (NCDOT) shall be required to be in full
compliance with the conditions related to construction activities within the most recent version
of their individual NPDES (NCS000250) stormwater permit.
5. Construction Moratoriums and Coordination
If activities must occur during periods of high biological activity (i e. sea turtle nesting, fish
spawning, or bird nesting), then biological monitoring may be required at the request of other
state or federal agencies and coordinated with these activities.
All moratoriums on construction activities established by the NC Wildlife Resources
Commission (WRC), US Fish and Wildlife Service (USFWS), NC Division of Marine Fisheries
(DMF), or National Marine Fisheries Service (NMFS) to lessen impacts on trout, anadromous
fish, larval/post-larval fishes and crustaceans, or other aquatic species of concern shall be
implemented. Exceptions to this condition require written approval by the resource agency
responsible for the given moratorium.
Water Quality Certification No. 3900

Water Qualitv Certification No. 3900
Work within the twenty-five (25) designated trout counties or identified state or federal
endangered or threatened species habitat shall be coordinated with the appropriate WRC,
USFWS, NMFS, and/or DMF personnel.
6. Dredging shall not cause Shellfish Closures
The effluent water from the dredge spoil should not be released into open shellfish waters.
Shellfish Sanitation and the Division of Water Quality must be notified if this is to occur.
7. Work in the Dry
All work in or adjacent to stream waters shall be conducted so that the flowing stream does
not come in contact with the disturbed area. Approved best management practices from the
most current version of the NC Sediment and Erosion Control Manual, or the NC DOT
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams,
and other diversion structures shall be used to minimize excavation in flowing water.
Exceptions to this condition require application submittal to and written approval by the
Division.
8. Riparian Area Protection (Buffer) Rules
Activities located in the protected riparian areas (whether jurisdictional wetlands or not),
within the Neuse, Tar -Pamlico, or Catawba River Basins or in the Randleman, Jordan, or
Goose Creek Watersheds (or any other basin or watershed with buffer rules) shall be limited
to "uses identified within and constructed in accordance with 15A NCAC 02B .0233, .0259,
0243, .0250, .0267 and .0605, and shall be located, designed, constructed, and maintained
to have minimal disturbance to protect water quality to the maximum extent practicable
through the use of best management practices. All buffer rule requirements, including diffuse
flow requirements, must be met.
9. If concrete is used during the construction, then all necessary measures shall be taken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state
due to the potential for elevated pH and possible aquatic life/ fish kills.
10. Compensatory Mitigation
In accordance with 15A NCAC 02H .0506 (h), compensatory mitigation may be required for
losses of equal to or greater than 150 linear feet of streams (intermittent and perennial)
and/or equal to or greater than one (1) acre of wetlands. For linear public transportation
projects, impacts equal to or exceeding 150 linear feet per stream shall require mitigation.
Buffer mitigation may be required for any project with Buffer Rules in effect at the time of
application for activities classified as "Allowable with Mitigation" or "Prohibited" within the
Table of Uses.
A determination of buffer, wetland, and stream mitigation requirements shall be made for any
General Water Quality Certification for this Nationwide and/or Regional General Permit.
Design and monitoring protocols shall follow the US Army Corps of Engineers Wilmington
District Stream Mitigation Guidelines (April 2003) or its subsequent updates. Compensatory
mitigation plans shall be submitted to the Division for written approval as required in those
protocols. The mitigation plan must be implemented and/or constructed before any impacts
occur on site. Alternatively, the Division will accept payment into an in -lieu fee program or a
mitigation bank. In these cases, proof of payment shall be provided to the Division before
any impacts occur on site.
Water Quality Certification No. 3900 4

11. Placement of Culverts and Other Structures in Waters and Wetlands
Culverts required for this project shall be designed and installed in such a manner that the
original stream profiles are not altered and allow for aquatic life movement during low flows.
Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal
profile) must be maintained above and below locations of each culvert.
Placement of culverts and other structures in waters and streams must be below the
elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches,
and 20 percent of the culvert diameter for culverts having a diameter less than or equal to 48
inches, to allow low flow passage of water and aquatic life.
When topographic constraints indicate culvert slopes of greater than 5%, culvert burial is not
required, provided that all alternative options for flattening the slope have been investigated
and aquatic life movement/ connectivity has been provided when possible (rock ladders,
crossvanes, etc). Notification to the Division including supporting documentation to include a
location map of the culvert, culvert profile drawings, and slope calculations shall be provided
to the Division 60 days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required provided that there
is sufficient documentation of the presence of bedrock. Notification to the Division including
supporting documentation such as, but not limited to, a location map of the culvert,
geotechnical reports, photographs, etc shall be provided to the Division a minimum of 60
days prior to the installation of the culvert. If bedrock is discovered during construction, then
the Division shall be notified by phone or email within 24 hours of discovery.
If other site -specific topographic constraints preclude the ability to bury the culverts as
described above and/or it can be demonstrated that burying the culvert would result in
destabilization of the channel, then exceptions to this condition require application submittal
to, and written approval by, the Division of Water Quality, regardless of the total impacts to
streams or wetlands from the project.
Installation of culverts in wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. Additionally, when
roadways, causeways, or other fill projects are constructed across FEMA-designated
floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the floodway that may
result in destabilization of streams or wetlands.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable instead of riprap or other bank hardening
methods.
12. All temporary fill and culverts shall be removed and the impacted area returned to natural
conditions within 60 days of the determination that the temporary impact is no longer
necessary. The impacted areas shall be restored to original grade, including each stream's
original cross sectional dimensions, plan form pattern, and longitudinal bed and bed profile,
and the various sites shall be stabilized with natural woody vegetation (except for the
approved maintenance areas) and restored to prevent erosion.
13, All temporary pipes/ culverts/ riprap pads etc, shall be installed in all streams as outlined in
the most recent edition of the North Carolina Sediment and Erosion Control Planning and
Design Manual or the North Carolina Surface Mining Manual so as not to restrict stream flow
or cause dis-equilibrium during use of this General Certification.
Water Quality Certification No. 3900

Water Quality Certification No. 3900
14. Any riprap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All rip -rap shall buried and/or "keyed in" such that the original stream
elevation and streambank contours are restored and maintained. Placement of rip -rap or
other approved material's shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area.
15. Any rip -rap used for stream stabilization shall be of a size and density so as not to be able to
be carried off by wave, current action, or stream flows and consist of clean rock or masonry
material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed
except in specific areas required for velocity control and to ensure structural integrity of bank
stabilization measures.
16, If this Water Quality Certification is used to access building sites, then all lots owned by the
applicant must be buildable without additional impacts to streams or wetlands. The applicant
is required to provide evidence that the lots are buildable without requiring additional impacts
to wetlands, waters, or buffers if required to do so in writing by the Division. For road
construction purposes, this Certification shall only be utilized from natural high ground to
natural high ground.
17. Deed notifications or similar mechanisms shall be placed on all retained jurisdictional
wetlands, waters, and protective buffers within the project boundaries in order to assure
compliance for future wetland, water, and buffer impact. These mechanisms shall be put in
place at the time of recording of the property or of individual lots whichever is appropriate. A
sample deed notification can be downloaded from the Division's web site at
http //portal ncdenr org/web/wq/swp/ws/401/certsandpermits/apply/forms. The text of the
sample deed notification may be modified as appropriate to suit to a specific project.
Documentation of deed notifications shall be provided to the Division upon request.
18. If an environmental document is required under the National or State Environmental Policy
Act (NEPA or SEPA), then this General Certification is not valid until a Finding of No

New Hanover County, Carolina Beach Inlet:
Email Transmittal
On 6 October, the US Army Corps of Engineers (USACE) notified New Hanover County (NHC)
of a potential November maintenance dredging opportunity for the Carolina Beach Inlet (CBI).
The special purpose dredge Murden is scheduled to leave the area in late November for Dare
County and the Northeast. Considering the Murden's travel path, the US Coast Guard's (USCG)
ongoing asset requirement and current inlet template conditions; a mid to late November hopper
dredging event with inshore dredge material management site (IDMMS) usage is advantageous.
NHC and the USACE are proposing a three to six -day maintenance dredging event predicated on
the Murden's availability and schedule. The proposed event would make use of the IDMMS as
authorized by the NC Division of Coastal Management (NCDCM) Permit 50-16, expiration date
12/2020 (NHC's renewal request in progress). However, the November availability of a USACE
hopper dredge could place the proposed maintenance event outside NHC's IDMMS'
environmental window. Understanding the USACE's dredge plant forecasting challenges, NHC
is requesting an early November out of window event as an operational precaution. In support of
the potential out of window maintenance event, NHC is providing supplemental documentation
as previously requested by the NC Division of Coastal Management (NCDCM), the NC Division
of Marine Fisheries (NCDMF) and the National Marine Fisheries Service (NMFS).
Supplemental Documentation
Statement of purpose and need specific to this event:
• Maintaining CBI as an ocean accessible route from Myrtle Grove Sound and adjacent
NHC estuarine areas;
• Responding to shoaled conditions and the USCG's mandated year-round aids to
navigation (ATONs) access and
• Implementing a resource conservation and adaptive dredge material management
alternative, the IDMMS.
Dredge and disposal schedule for proposed work:
• A three to six -day maintenance event making use of the IDMMS;
• The Murden mobilizing from the local shipyard in mid to late November and
• CBI maintenance dredging occurring in November followed by the Murden's
demobilization to the Northeast.

ESTIMATED AVAILABLE SPACE @ -14 FT IN
PROPOSED PLACEMENT AREA AS OF April 7-9, 2020:
74,062 CY
BOX CUT
IDMMS inset:
• Before dredge surveys will be scheduled with updated template dredge volumes;
• The IDMMS deposition location and capacity will be re -mapped;
• The last IDMMS usage was in April 2020 and
• A post -construction survey and summary will be provided.
Volume estimate of IDMMS placement:
• CBI's IDMMS deposition authorization is 75,000 cubic yards within CB's three-year
coastal storm damage reduction (CSDR) project cycle. The IDMMS has approximately
31,000 cubic yards of authorized deposition remaining in the current three-year cycle;
• The USACE's Coastal Engineering opinion of the IDMMS inset's deposition capacity
will be requested;
• The dredge event is potentially 6 days at 12-hour days. If the Murden were to maximize
72 hours of dredging at —200 cubic yards/hour, the event volume managed would be
approximately 14,400 cy, well within DCM's regulatory stipulations.
Record of most recent sand recvcling from the IDMMS:
• The last recycling/reuse of beach quality sand from the CSDR's IDMMS occurred in
early 2019 and is scheduled again for FY22.
Forecast of next disposal event planned for the IDMMS:
• As per the USACE's upcoming shipyard visits and the fleet's US East Coast
responsibilities, the USACE will continue abbreviated but repetitive visits within NC's
shallow draft inlets;
• The US East Coast scheduling of the USACE's dredge fleet is completely a USACE
responsibility;
• In efforts to meet the USCG's mandate for the buoy tender Bayberry's access, CBI
maintenance is tentatively targeted every eight to ten weeks and
• NHC prefers and requests USACE special purpose dredges using the IDMMS, resulting
in improved operational efficiency (reduced dredge plant travel time), improved sediment
management (pre -staged recycling within the IDMMS) and reduced environmental
effects (avoiding surf -zone nearshore nursery areas and nearshore staging areas).

Given the USACE's special purpose dredge fleets' schedules/timelines and in keeping with the
NCDCM Major Permit 50-16 stipulations, NHC is requesting the agencies accept this transmittal
as NHC's pre -construction IDMMS communication.
NHC thanks all for your consideration!
