All proposed fill or modification of wetlands and/or waters, including streams and streambanks,
under this General Certification requires application to, and written approval from the Division of
Water Quality (the "Division"), regardless of the purpose of the restoration, enhancement,
stabilization, or creation activity.
Bank Stabilization projects qualifying for Nationwide Permit 13 for erosion protection of up to 500
feet of stream banks to protect property are exempt from the requirement for written approval.
Any impacts to riparian buffers associated with this work in the Neuse, Tar-Pamlico, Randleman
and Catawba River Basins (or any other basins with Riparian Area Protection Rules [Buffer - - R -
Rules] in effect at the time of application [in accordance with 15A NCAC 2B .0200]) will require
written approval, unless the activities are listed as "EXEMPT" from these Rules.
In accordance with North Carolina General Statute Section 143-215.3D(e), written approval for a
401 Water Quality General Certification must include the appropriate fee. If a project also
requires a CAMA Permit, then one payment to both agencies shall be submitted and will be the
higher of the two fees.
Conditions of Certification:
1. Activities shall meet the definitions, design, and monitoring protocols specified within the US
Army Corps of Engineers Wilmington District Regulatory Guidance Letter (RGL02-02) and
the Stream Mitigation Guidelines (April 2003) or any subsequent updates to these
documents.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas

Water Quality Certification No. 3689
Water Quality Certification No. 3689
Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
3. 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. 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.
b. 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 Caroling Surface Mining Manual.
c. Reclamatior measures and implementation must comply 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, except for publicly
funded linear transportation projects when materials can be accessed offsite in a timely
manner..
e. If the project occurs in waters or watersheds classified as Primary Nursery Areas
(PNA's), Trout Jr), SA, WS-I, WS-II, High Quality (HQW), or Outstanding Resource
(ORW) waters, then the sediment and erosion control requirements contained within
Design Standards in Sensitive Watersheds (15A NCAC 04B.0124) supercede all other
sediment and erosion control requirements.
4. No Sediment and Erosion Control Measures in Wetlands or Waters
Sediment and erosion control measures should not be placed in wetlands or waters outside
of the permitted impact areas without prior approval by the Division. If placement of sediment
and erosion control devices in wetlands and waters is unavoidable, design and placement of -
temporary erosion control measures shall not be conducted in a manner that may result in
dis-equilibrium of wetlands or stream beds or banks, adjacent to or upstream and down
stream 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 or locally delegated program has released the project.
5. Construction Stormwater Permit NCG010000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of
Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program,
an NPDES General stormwater permit (NCG010000) administered by the Division is
automatically issued to the project. This General Permit allows stormwater to be discharged
during land disturbing construction activities as stipulated by conditions in the permit. If your
project is covered by this permit [applicable to construction projects that disturb one (1) or
more acres], full compliance with permit conditions including the sedimentation control plan,
self-monitoring, record keeping and reporting requirements are required. A copy of this
permit and monitoring report forms may be found at
httallh2o.enr.state.nc.us/su/Forms Documents.htm.
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.
Water Quality Certification No. 3689
Water Quality Certification No. 3689
6. Construction Moratoriums and Coordination
If activities must occur during periods of high biological activity (i.e. sea turtle or bird nesting),
then biological monitoring may be required at the request of other state or federal agencies
and coordinated with these activities. This condition can be waived through written
concurrence on a case by case basis upon reasonable justification.
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. This condition can be waived through written concurrence on a case by case
basis upon reasonable justification.
Work within the twenty-five (25) designated trout counties or identified state or federal
endangered or threatened species habitp.i shall be coordinated with the appropriate W RC,
USFWS, NMFS, and/or DMF personae'..
NC Wildlife Resources Commission will not object to construction of Natural Resources
Conservation Service (NRCS) 'urgent and compelling' sites during the spawning period
provided these projects are, to the extent appropriate and practical, constructed by:
a. Using flow diversion structures such as sandbags;
b. Placing large-size rock toes and filter cloth backing for stabilization sites before
backfilling; and
c. Excavating new channel alignments in dry areas.
Construction at non= urgent and compelling' sites shall not occur during the spawning period
to minimize the potential adverse effects of multiple construction activities on trout or
anadromous fish resources in this stream.
7. Work in the Dry
All work in or adjacent to stream waters shall be conducted in a dry work 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 submittal to, and approval
by, the Division.
8. Riparian Area Protection (Buffer) Rules
Activities located in the protected 50-foot wide riparian areas (whether jurisdictional wetlands
or not) within the Neuse, Tar-Pamlico, Randleman, Catawba (or any other basin with buffer
rules), shall be limited to "uses" identified within and constructed in accordance with 15A
NCAC 2B .0233,.0259, .0250 and .0243, 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. Water Supply Watershed Buffers
The 100-foot wide (high-density development) or the 30-foot wide vegetative buffer (all other
development) must be maintained adjacent to all perennial waters except for allowances as
Water Quality Certification No. 3689
Water Quality Certification No. 3689
provided in the Water Supply Watershed Protection Rules [15A NCAC 2B .0212 through
.0215].
10. If concrete is used during the construction, then a dry work area should be maintained to
prevent direct contact between curing concrete and stream water. Water that inadvertently
contacts uncured concrete should not be discharged to surface waters due to the potential for
elevated pH and possible aquatic life/ fish kills.
11. 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.
12. If an environmental document is required under NEPA or SEPA,-then this General
Certification is not valid until a Finding of No Significant Impact or Record of Decision is
issued by the State Clearinghouse.
13. Additional site-specific conditions may be added to the written approval attached to this
Certification in order to ensure compliance with all applicable water quality and effluent
standards.
14.This Certification shall expire three (3) years from the date of the approval letter from DWQ or
on the same day as the corresponding Nationwide Permit. In accordance with General
Statute 136-44.76, certifications issued to the NCDOT shall expire only upon expiration of the
federal 404 Permit. The conditions in effect on the date of issuance of Certification for a
specific project shall remain in effect for the life of the project, regardless of the expiration
date of this Certification. If the construction process for approved activities will overlap the
expiration and renewal date of the corresponding 404 Permit and the Corps allows for
continued use of the 404 Permit, then the General Certification shall also remain in effect
without requiring re-application and re-approval to use this Certification for the specific
impacts already approved.
15. The applicant/permittee and their authorized agents shall conduct all activities in a manner
consistent with State water quality standards (including any requirements resulting from
compliance with §303(d) of the Clean Water Act), and any other appropriate requirements of
State and Federal Law. If the Division determines that such standards or laws are not being
met, including failure to sustain a designated or achieved use, or that State or Federal law is
being violated, or that further conditions are necessary to assure compliance, then the
Division may reevaluate and modify this General Water Quality Certification.
16. Certificate of Completion
When written authorization is required for use of this certification, upon completion of all
permitted impacts included within the approval and any subsequent modifications, the
applicant shall be required to return the certificate of completion attached to the approval.
One copy of the certificate shall be sent to the DWQ Central Office in Raleigh at 1650 Mail
Service Center, Raleigh, NC, 27699-1650.
Non-compliance with or violation of the conditions herein set forth by a specific project shall result
in revocation of this Certification for the project and may also result in criminal and/or civil
penalties.
