RIPARIAN RESTORATION AND CREATION ACTIVITIES CERTIFICATION
GENERAL CERTIFICATION FOR STREAM RESTORATION, ENHANCEMENT AND
STABILIZATION PROJECTS AND WETLAND AND RIPARIAN RESTORATION AND
CREATION ACTIVITIES INCLUDING THOSE ELIGIBLE FOR CORPS OF ENGINEERS
NATIONWIDE PERMIT NUMBERS 13 (BANK STABILIZATION) AND 27 (WETLAND AND
RIPARIAN RESTORATION AND CREATION) AND REGIONAL PERMIT 197800080
(CONSTRUCTION AND MAINTENANCE OF BULKHEADS)
This General Certification is issued in conformity with the requirements of Section 401, Public
Laws 92-500 and 95-217 of the United States and subject to the North Carolina Division of Water
Quality Regulations in 15A NCAC 2H .0500 and 15A NCAC 26 .0200 for the discharge of fill
material to waters as described in 33 CFR 330 Appendix A (B) (13) and (27) of the Corps of
Engineers regulations (i.e. Nationwide Permit Numbers 13 and 27) and Regional Permit
197800080. The category of activities shall include stream bank stabilization or stream
restoration activity as long as impacts to waters or significant wetlands are minimized. This
Certification replaces Water Quality Certification (WQC) Number 3399 issued March 2003. This
WQC is rescinded when the. Corps of Engineers reauthorize Nationwide Permits 13 or 27 or
Regional Permit 197800080 or when deemed appropriate by the Director of the Division of Water
Quality (DWQ).
The State of North Carolina certifies that the specified-category of activity will not violate
applicable portions. of Sections 301, 302, 303, 306 and 307 of the Public Laws 92-500 and 95-217
if conducted in accordance with the conditions set forth.
Conditions of Certification:
1. Wetland and/or riparian area restoration and creation projects which are for
compensatory mitigation or compensatory mitigation credit (and not including
projects that only involve stream restoration or enhancement work described in
condition nos. 2 and 3 below) that are proposed under this General Certification
require written application to and approval from the Division of Water Quality. All
applications for written DWQ approval will be reviewed and a response will be
prepared within 30 days of stamped receipt of the application in the Division of
Water Quality's Central Office in Raleigh. This 30-day period does not include time
spent by the application or DWQ's response within US Postal Service or North
Carolina's Mail Service Center mail systems;
Wetland and riparian area restoration and creation projects (not including projects
that involve work in or impacts to streams) which are not for compensatory
mitigation or compensatory mitigation credit proposed under this General
Certification do not require written application to and approval from the Division of
Water Quality. In these cases, the applicant is required to notify the Division in
writing with three copies of project specifications before the impactoccurs. If the
Division determines that the project would not result in an ecologically viable wetland
and riparian area, then the Division shall prepare a response to notify the applicant
in writing within 30 days of DWQ's receipt of the notification. In such cases, the
applicant will be required to submit a formal application and pay of the appropriate
fee, and DWQ will be required to process the application through normal
procedures;
2. Proposed stream restoration projects (as defined and limited below), that do not
disturb wetlands and that are not being conducted for compensatory mitigation or
compensatory mitigation credit do not require written application to and approval

WQC #3495
from the Division of Water Quality, and, therefore, do not require payment of an
application fee to the Division of Water Quality. Projects that are intended for
compensatory mitigation or compensatory mitigation credit, that are intended to
resolve a violation, or that are in association with a development project shall require
an application, fee, and written concurrence from the Division of Water Quality.
Stream restoration is defined as the process of converting an unstable, altered or
degraded stream corridor, including adjacent riparian zone and floodprone areas to
its natural or referenced, stable conditions considering recent and future watershed
conditions. This biological and chemical integrity, including transport of water and
sediment is produced by the stream's watershed in order to achieve dynamic
equilibrium. The applicant is required to notify the Division in writing with three
copies of detailed restoration plans and specifications before the impact occurs. If
the Division determines that the project does not meet the above definition of stream
restoration, then the Division shall notify the applicant in writing within 30 days of
receipt of the application. In such cases, the applicant will be required to submit a
formal application and pay of the appropriate fee, and DWQ will be required to
process the application through normal procedures;
3. Stream enhancement projects (as defined and limited below), that do not disturb
wetlands and that are not being conducted for compensatory mitigation or
compensatory mitigation credit and do not include any stream channel relocation, do
not require written application to and approval from the Division of Water Quality,
and, therefore, do not require payment of an application fee to the Division of Water
Quality. Projects that are intended for compensatory mitigation or compensatory
mitigation credit, that are intended to resolve a violation, or that are in association
with a development project shall require an application, fee, and written concurrence
from the Division of Water Quality.
4. Stream enhancement is defined as the process of implementing stream
rehabilitation practices in order to improve water quality andlor ecological function.
These practices must only be conducted on streams that are not experiencing
severe aggradation or erosion. Stream enhancement does not include the relocation
of the stream channel. Stream enhancement bank stabilization techniques include
the use of woody vegetation as the primary means of long term stability, and "soft"
techniques such as root wads that encourage the establishment of dense woody
vegetation. Stream enhancement techniques do not typically include the use of
stream bank or bed hardening techniques such as rip-rap or other rock, gabion,
block or concrete structures. However, enhancement activities may also include the
placement of in stream habitat or grade control structures such as cross vanes, j-
hookvanes, and wing deflectors that do not affect the overall dimension, pattern, or
profile of a stable stream.
The applicant is required to notify the Division in writing with three copies of detailed
enhancement plans and specifications before the impact occurs if the stream
enhancement project disturbs greater than 500 feet of stream bank or if the project
proposes the use of in stream structures. If the Division determines that the project
does not meet the above definition of stream enhancement, then the Division shall
notify the applicant in writing with an explanation within 30 days of receipt of the
notification to require application and payment of the appropriate fee;
5. Stream stabilization projects that include the use of any structure or fill in the existing
stream bed or disturb greater that 500 feet of stream bank that are proposed under
this General Certification require written application to and approval from the
Division of Water Quality.

WQC #3495
Stream stabilization is defined as the in-place stabilization of an eroding stream
bank using measures that consist primarily of "hard" engineering, such as but not
limited to concrete lining; rip rap or other rock, and gabions. The use of "hard"
engineering will not be considered as stream restoration or enhancement;
6. Impacts to any stream length in the Neuse, Tar-Pamlico or Randleman River Basins
(or any other major river basins with Riparian Area Protection Rules [Buffer Rules] in
effect at the time of application} requires written concurrence for this Certification
from DWQ in accordance with 15A NCAC 2B.~200. Activities listed as "exempt"
from these rules do not need to apply for written concurrence under this
Certification. New development activities located in the protected 50-foot wide
riparian areas (whether jurisdictional wetlands or not} within the Neuse and Tar-
Pamlico River Basins shall be limited to "uses" identified within and constructed in
accordance with 15A NCAC 2B .0200. All new development 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;
7. In order for the above conditions to be valid, any plans not requiring written
concurrence to use this Certification must be built according to the plans provided to
the Division of Water Quality. If written concurrence is required, then the project
must be built and maintained according to tf~e plans approved by the written
concurrence and. Certification from the Division of Water Quality;
8. Appropriate sediment and erosion control practices which equal or exceed those
outlined in the most recent version of the "North Carolina Erosion and Sediment ~-
Control Planning and Design Manual" or "North Carolina Surface Mining Manual" ~-
whichever is more appropriate (available from the Division of Land Resources at the
DENR Regional and Central Offices} shall be designed, installed and maintained
properly to assure compliance with the appropriate turbidity water quality standard
(50 NTUs in streams and rivers not designated as trout waters by DWQ; 25 NTUs in
all saltwater classes and all lakes and reservoirs; l0 NTUs in DWQ-classified trout
waters};
9. All sediment and erosion control measures placed in wetlands or waters shall be
removed and the original grade restored after the Division of Land Resources or
delegated program has released the project;
10. Any rip-rap shall be of such a size and density so as not to be able to be carried off
by wave or current action 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. If rip-rap is to be installed within the streambed, the amount
and location must be approved in writing by the Division of Land Resources and
Division of Water Quality. However rock vanes, wing deflectors, and similar
structures for grade control and bank protection are acceptable;
11. Measures shall be taken to prevent live or fresh concrete from coming into contact
with freshwaters of the state until the concrete has hardened;
12. If an environmental document is required, this Certification is not valid until a Finding
of No Significant Impactor Record of Decision is issued by the State
Clearinghouse;

WQC #3495
13. Additional site-specific conditions may be added to projects which require written
concurrence under this Certification in order to ensure compliance with all applicable
water quality and effluent standards;
14. Projects with any impacts to streams, wetlands, and/or waters that have received a
Notice of Violation from the Division of Land Resources and/or the Division of Water
Quality are required to submit a complete application and receive written
concurrence to use this Certification regardless of the proposed impact amount to
streams, wetlands, and~,waters;
15. Concurrence from DWQ that this Certification applies to an individual project shall
expire three years from the date of the cover letter from DWQ or the notification sent
to DWQ;
16. Standard Erosion and Sediment Control Practices:
Erosion and sediment control practices must be in full compliance with all
specifications governing the proper design, installation and operation and
maintenance of such Best Management Practices:
a. Erosion and sediment control measures for the project must be designed,
installed,. operated, and maintained in accordance with the most recent version
of the North Carolina Sediment and Erosion Control Planning and Design
Manual
b. Design, installation, operation, and maintenance of the sediment and erosion
control measures must be such that they equal, or exceed, the requirements
specified in the most recent version of the North Carolina Sediment and Erosion
Control Manual. The devices shall be maintained on all construction sites,
borrow sites, and waste pile (spoil) projects, including contractor-owned or
leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be
designed, installed, operated, and maintained in accordance with the most
recent version of the North Carolina Surface Mining Manual.
d. Reclamation measures and implementation must comply with the reclamation in
accordance with the requirements of the Sedimentation Pollution Control Act.
e. Sufficient materials required for stabilization and/or repair of erosion control
measures and stormwater routing and treatment shall be on site at all times.
17. No Impacts Beyond those in Application
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian
areas beyond the footprint of the impacts depicted in the Pre-construction
Notification. 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.
18. No Sediment and Erosion Control Measures in Wetlands
Sediment and erosion control measures shall not be placed in wetlands or waters to
the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources or locally delegated program has released the project.
