c. Reclamation measures and implementation must comply with the reclamation in
accordance with the requirements of the Sedimentation Pollution Control Act and
the Mining Act of 1971.
d. Sufficient materials required for stabilization and/or repair of erosion control
measures and stormwater routing and treatment shall be on site at all times.
11. Sediment and erosion control measures shall not be placed in wetlands or waters unless
otherwise approved in this Certification. 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 DEMLR or
the locally delegated program has released the specific area within the project. [15A NCAC
02H .0501 and .0502]

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. [15A
NCAC 02H .0506(b)(3) and (c)(3)]
13. 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. [15A NCAC 02B .0200]

Placement of culverts and other structures in waters, streams must be below the elevation of
the streambed by one (1) 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 48 inches, to allow
low flow passage of water and aquatic life.
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 rip rap or other bank hardening
methods.
15. Any riprap used for stream stabilization shall be of a size and density to prevent movement by
wave action, current action, or stream flows and consist of clean rock or masonry material
free of debris or toxic pollutants. Riprap shall not be installed in the streambed except in
specific areas required for velocity control and to ensure integrity of bank stabilization
measures. [15A NCAC 02H 0506(b)(2)]
16. A one-time application of fertilizer to re-establish vegetation is allowed in disturbed areas,
but is restricted to no closer than 10 feet from waters. Any fertilizer application must comply
with all other Federal, State and Local regulations. [15A NCAC 02B .0200]

spans the entire bed and both banks of the stream, is only used for a road, driveway or path
crossing, and is not mitered to follow the stream pattern. Impacts for dam footprints and
flooding will count toward the threshold for stream impacts, but flooding upstream of the dam
will not count towards mitigation requirements as long as no filling, excavation, relocation or
other modification of the existing stream dimension, pattern or profile occurs. Any filling,
excavation, relocation or other modification of the existing stream (other than flooding) must
re-establish the same dimensions, patterns and profiles of the existing channel (or those of a
stable reference reach if the existing channel is unstable)
Isolated Lakes and Ponds ' -- Impacts to isolated waters other than streams and wetlands as
determined by the Division of Water Quality shall be measured as area. Permanent and/or
temporary water impacts shall be enumerated on the entire project for all impacts proposed
regardless of which 404 Nationwide Permits are used (if any). Any activity that results in a
loss of use of aquatic functions including but not limited to filling, draining, and dredging shall
be considered waters impacts.
Isolated and Other Non-404 Wetlands - Impacts to isolated and other non-404 wetlands as
determined by the Division of Water Quality shall be measured as area. Permanent and/or
temporary wetland impacts shall be enumerated on the entire project for all impacts. Any
activity that results in a loss of use of wetland functions including but not limited to filling,
excavating, draining, and flooding shall be considered wetland impacts. Impacts to wetlands
shall include activities that change the hydrology of a wetland.
2. No Impacts Beyond those Authorized in the Written Approval or Beyond the Threshold of Use
of this Permit
No waste, spoil, solids, or fill of any kind shall occur in isolated and other non-404 wetlands,
isolated waters, or isolated riparian areas beyond the footprint of the impacts depicted in the
Pre-Construction Notification, as authorized in the written approval from the Division, or
beyond the thresholds established for use of this Permit without written authorization,
including incidental impacts. All construction activities, including the design, installation,
operation, and maintenance of sediment and erosion control Best Management Practices,
shall be performed so that no violations of state water quality standards, statutes, or rules
occur. Approved plans and specifications for this project are incorporated by reference and
are enforceable parts of this permit.

If activities must occur during periods of high biological activity (Le. 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.
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.
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

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.
In accordance with 15A NCAC 02H .1305 (c) & (d), 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 total wetland impacts, including all impacts to
404 and non-404 wetlands (see examples in "Attachment B" at the end of this Permit). If
collective wetland impacts, including 404 and non-404 wetlands, are equal to or greater than
one (1) acre, compensatory mitigation is required. If the project requires a mitigation plan, but
is otherwise below the written approval thresholds described above, the applicant may
provide a courtesy copy of the Pre-Construction Notification along with a copy of the
mitigation plan. For linear, public transportation projects, impacts equal to or exceeding 150
linear feet per stream shall require mitigation.
Emmmfi�=

Buffer mitigation may be required for any project with Buffer Rules in effect at the time of
application for buffer impacts resulting from activities classified as "Allowable with Mitigation"
within the "Table of Uses" section of the Buffer Rules or require a variance under the Buffer
Rules,
A determination of buffer, wetland and stream mitigation requirements shall be made for any
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 for written Division 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.
11. Relocated stream designs should include the same dimensions, patterns, and profiles as the
existing channel (or a stable reference reach if the existing channel is unstable), to the
maximum extent practical. The new channel should be constructed in the dry and water shall
not be turned into the new channel until the banks are stabilized. Vegetation used for bank
stabilization shall be limited to native woody species, and should include establishment of a
30-foot wide wooded and an adjacent 20-foot wide vegetated buffer on both sides of the
relocated channel to the maximum extent practical. A transitional phase incorporating
appropriate erosion control matting materials and seedling establishment is allowable,
however matting that incorporates plastic mesh and/or plastic twine shall not be used in
wetlands, riparian buffers or floodplains as recommended by the North Carolina Sediment
and Erosion Control Manual, Rip-rap, A-Jacks, concrete, gabions or other hard structures
may be allowed if it is necessary to maintain the physical integrity of the stream; however, the
applicant must provide written justification and any calculations used to determine the extent
of rip-rap coverage. Please note that if the stream relocation is conducted as a stream
restoration as defined in the US Army Corps of Engineers Wilmington District, April 2003
Stream Mitigation Guidelines (or its subsequent updates), the restored length may be used
as compensatory mitigation for the impacts resulting from the relocation.
12, Stormwater Management Plan Requirements
All applications shall address stormwater management throughout the entire project area per
the 401 Stormwater Requirements, referenced herein as "Attachment A" at the end of this
Permit.
13. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed
across the bridge and pre-treated through site-appropriate means (grassed swales, pre-
formed scour holes, vegetated buffers, etc.) before entering the stream. Please refer to the
most current version of Stormwater Best Management Practices, Exceptions to this condition
require written approval by the Division.
14. 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.
15. If this General Permit 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 Permit shall only be utilized from natural high ground to natural
high ground.
16. 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 Drovertv or of individual lots. whichever is ar)l)ropriate. A
sample deed notification can be downloaded from the Division's web site at

streams, rivers and tidal waters in areas that are not subject to a state Riparian Area
Protection Rule or other more stringent vegetated setback requirements. The width of
the setback shall be measured horizontally from the normal pool elevation of impounded
structures, the top-of-bank of streams and rivers, and the mean high waterline of tidal
waters, perpendicular to shoreline. Vegetated setback and filters required by state rules
or local governments may be met concurrently with this requirement and may contain
coastal, isolated or 404 jurisdictional wetlands. Non-jurisdictional portions of the
vegetated setback may be cleared and graded, but must be planted with and maintained
3
