II. GENERAL CONDITIONS:
1. When written authorization is required, the plans and specifications for the project are
incorporated into the authorization by reference and are an enforceable part of the
Certification. Any modifications to the project require notification to DWR and may require
an application submittal to DWR with the appropriate fee. [15A NCAC 02H .0501 and .0502]
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the
footprint of the impacts (including temporary impacts) as authorized in the written approval
from DWR; or beyond the thresholds established for use of this Certification without
written authorization. [15A NCAC 02H .0501 and .0502]
No removal of vegetation or other impacts of any kind shall occur to state regulated riparian
buffers beyond the footprint of impacts approved in a Buffer Authorization or Variance or
as listed as an exempt activity in the applicable riparian buffer rules. [15A NCAC 02B .0200]
3. In accordance with 15A NCAC 02H .0506(h) and Session Law 2017-10, compensatory
mitigation may be required for losses of greater than 300 linear feet of perennial streams
and/or greater than one (1) acre of wetlands. Impacts associated with the removal of a
dam shall not require mitigation when the removal complies with the requirements of Part
3 of Article 21 in Chapter 143 of the North Carolina General Statutes. Impacts to isolated
and other non-404 jurisdictional wetlands shall not be combined with 404 jurisdictional
wetlands for the purpose of determining when impact thresholds trigger a mitigation
requirement. For linear publicly owned and maintained transportation projects that are not
determined to be part of a larger common plan of development by the US Army Corps of
Engineers, compensatory mitigation may be required for losses of greater than 300 linear
feet per perennial stream.
Compensatory stream and/or wetland mitigation shall be proposed and completed in
compliance with G.S. 143-214.11. For applicants proposing to conduct mitigation within a
project site, a complete mitigation proposal developed in accordance with the most recent
guidance issued by the US Army Corps of Engineers Wilmington District shall be submitted
for review and approval with the application for impacts.
4. All activities shall be in compliance with any applicable State Regulated Riparian Buffer
Rules in Chapter 2 of Title 15A.
5. When applicable, all construction activities shall be performed and maintained in full
compliance with G.S. Chapter 113A Article 4 (Sediment and Pollution Control Act of 1973).
Regardless of applicability of the Sediment and Pollution Control Act, all projects shall
incorporate appropriate Best Management Practices for the control of sediment and
erosion so that no violations of state water quality standards, statutes, or rules occur. [15A
NCAC 02H .0506(b)(3) and (c)(3) and 15A NCAC 02B .0200]

sites, including contractor -owned or leased borrow pits associated with the project.
Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times.
For borrow pit sites, the erosion and sediment control measures shall be designed,
installed, operated, and maintained in accordance with the most recent version of the
North Carolina Surface Mining Manual. Reclamation measures and implementation shall
comply with the reclamation in accordance with the requirements of the Sedimentation
Pollution Control Act and the Mining Act of 1971.
If the project occurs in waters or watersheds classified as Primary Nursery Areas (PNAs), SA,
WS-I, WS-II, High Quality Waters (HQW), or Outstanding Resource Waters (ORW), then the
sedimentation and erosion control designs shall comply with the requirements set forth in
15A NCAC 0413.0124, Design Standards in Sensitive Watersheds.
6. Sediment and erosion control measures shall not be placed in wetlands or waters except
within the footprint of temporary or permanent impacts authorized under this Certification.
Exceptions to this condition require application to and written approval from DWR. [15A
NCAC 02H .0501 and .0502]
7. Erosion control matting that incorporates plastic mesh and/or plastic twine shall not be
used along streambanks or within wetlands. Exceptions to this condition require
application to and written approval from DWR. [15A NCAC 026 .0201]
8. An NPDES Construction Stormwater Permit (NCG010000) is required for construction
projects that disturb one (1) or more acres of land. The NCGO10000 Permit allows
stormwater to be discharged during land disturbing construction activities as stipulated in
the conditions of the permit. If the 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. [15A
NCAC 02H .0506(b)(5) and (c)(5)]
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. [15A NCAC 02H
.0506(b)(5) and (c)(5)]

GC4137
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 to and written approval from DWR.
[15A NCAC 02H .0506(b)(3) and (c)(3)]
10. If activities must occur during periods of high biological activity (e.g. 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. [15A NCAC 02H
.0506(b)(2) and 15A NCAC 04B .0125]
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) shall be implemented. Exceptions to
this condition require written approval by the resource agency responsible for the given
moratorium. A copy of the approval from the resource agency shall be forwarded to DWR.
Work within a designated trout watershed of North Carolina (as identified by the
Wilmington District of the US Army Corps of Engineers), or identified state or federal
endangered or threatened species habitat, shall be coordinated with the appropriate WRC,
USFWS, NMFS, and/or DMF personnel.
11. Culverts 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. The dimension,
pattern, and profile of the stream above and below a pipe or culvert shall not be modified
by widening the stream channel or by reducing the depth of the stream in connection with
the construction activity. The width, height, and gradient of a proposed culvert shall be
such as to pass the average historical low flow and spring flow without adversely altering
flow velocity. [15A NCAC 02H .0506(b)(2) and (c)(2)]
Placement of culverts and other structures in streams shall be below the elevation of the
streambed by one foot for all culverts with a diameter greater than 48 inches, and 20% 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.
If multiple pipes or barrels are required, they shall be designed to mimic the existing stream
cross section as closely as possible including pipes or barrels at flood plain elevation and/or
sills where appropriate. Widening the stream channel shall be avoided.
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 (e.g.
rock ladders, cross vanes, etc.). Notification, including supporting documentation to include
a location map of the culvert, culvert profile drawings, and slope calculations, shall be
provided to DWR 60 calendar days prior to the installation of the culvert.
Page 5 of 9

GC4137
When bedrock is present in culvert locations, culvert burial is not required provided that
there is sufficient documentation of the presence of bedrock. Notification, including
supporting documentation such as, a location map of the culvert, geotechnical reports,
photographs, etc. shall be provided to DWR a minimum of 60 calendar days prior to the
installation of the culvert. If bedrock is discovered during construction, then DWR 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 to and
written approval from DWR.
Installation of culverts in wetlands shall ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. When roadways,
causeways, or other fill projects are constructed across FEMA-designated floodways or
wetlands, openings such as culverts or bridges shall 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 shall be used where practicable instead of rip -rap or other bank hardening
methods.
12. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be
directed across the bridge and pre-treated through site -appropriate means to the maximum
extent practicable (e.g. grassed swales, pre -formed scour holes, vegetated buffers, etc.)
before entering the stream. Exceptions to this condition require application to and written
approval from DWR. [15A NCAC 02H .0506(b)(5)]
13. Application of fertilizer to establish planted/seeded vegetation within disturbed riparian
areas and/or wetlands shall be conducted at agronomic rates and shall comply with all
other Federal, State and Local regulations. Fertilizer application shall be accomplished in a
manner that minimizes the risk of contact between the fertilizer and surface waters. [15A
NCAC 02B .0200 and 15A NCAC 02B .0231]
14. If concrete is used during 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.
[15A NCAC 02B .0200]
15. All proposed and approved temporary fill and culverts shall be removed and the impacted
area shall be returned to natural conditions within 60 calendar days after the temporary
impact is no longer necessary. The impacted areas shall be restored to original grade,
including each stream's original cross sectional dimensions, planform pattern, and
longitudinal bed profile. For projects that receive written approval, no temporary impacts
are allowed beyond those included in the application and authorization. All temporarily
Page 6 of 9

GC4137
impacted sites shall be restored and stabilized with native vegetation. [15A NCAC 02H
.0506(b)(2) and (c)(2)]
16. All proposed and approved temporary pipes/culverts/rip-rap pads etc. in streams shall be
installed 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 or the
North Carolina Department of Transportation Best Management Practices for Construction
and Maintenance Activities so as not to restrict stream flow or cause dis-equilibrium during
use of this Certification. [15A NCAC 02H .0506(b)(2) and (c)(2)]
17. Any rip -rap 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 be placed such that the original stream
elevation and streambank contours are restored and maintained. Placement of rip -rap or
other approved materials shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area or in a manner that precludes aquatic life passage.
[15A NCAC 02H .0506(b)(2)]
18. Any rip -rap used for stream or shoreline stabilization shall be of a size and density to
prevent movement by wave, current action, or stream flows and shall 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. [15A NCAC 02H .0506(b)(2)]
19. Applications for rip -rap groins proposed in accordance with 15A NCAC 07H .1401 (NC
Division of Coastal Management General Permit for construction of Wooden and Rip -rap
Groins in Estuarine and Public Trust Waters) shall meet all the specific conditions for design
and construction specified in 15A NCAC 07H .1405.
20. All mechanized equipment operated near surface waters shall be inspected and maintained
regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids,
or other toxic materials. Construction shall be staged in order to minimize the exposure of
equipment to surface waters to the maximum extent practicable. Fueling, lubrication and
general equipment maintenance shall be performed in a manner to prevent, to the
maximum extent practicable, contamination of surface waters by fuels and oils. [15A NCAC
02H .0506(b)(3) and (c)(3) and 15A NCAC 026 .0211 (12)]
21. Heavy equipment working in wetlands shall be placed on mats or other measures shall be
taken to minimize soil disturbance. [15A NCAC 02H .0506(b)(3) and (c)(3)]
22. In accordance with 143-215.85(b), the applicant shall report any petroleum spill of 25
gallons or more; any spill regardless of amount that causes a sheen on surface waters; any
petroleum spill regardless of amount occurring within 100 feet of surface waters; and any
petroleum spill less than 25 gallons that cannot be cleaned up within 24 hours.
