The project shall be constructed in accordance with your application received Apri124,2017 and modification
request received January 31, 2018. After reviewing your application, we have decided that these impacts are
covered by General Water Quality Certification Number 4135. This certification corresponds to the Nationwide
Permit 14 issued by the Corps of Engineers. This approval is also valid for the Neuse Riparian Buffer Rules (15A
NCAC 2B.0233). In addition, you should acquire any other federal, state or loca] permits before you proceed with
your project including (but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply
Watershed regulations. This approval will expire with the accompanying 404 permit.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the NCDWR and submit a new application. If the property is sold, the
new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the future) exceed I50 linear feet, compensatory mitigation may be required as
described in 15A NCAC 2H .0506 (h) (6) and (7). Additional buffer impacts may require compensatory mitigation
as described in 15A NCAC 2B.0233. For this approval to remain valid, you must adhere to the conditions listed in
the General Certification and any additional conditions listed below.
Conditions of Certification:
I. Channel relocations shall be built as described in your application. Channels shall be completed and fully
stabilized, prior to diverting water into the new stream. Stream banks shall be matted with coir-fiber
matting. Vegetation used for bank stabilization shall be limited to native riparian vegetation, and should include
establishment of a vegetated buffer on both sides of the relocated channel to the maximum extent practical. Also, rip-
rap may be allowed if it is necessary to maintain the physical integrity of the stream, but the applicant must be able to
provide written justification and any calculations used to determine the extent of rip-rap coverage requested. Once the
stream has been turned into the new channel, it may be necessary to relocate stranded fish to the new channel to
prevent fish kills. [15A NCAC 02H .0506(b)(3)] .
2. For all areas permitted as Temporary riparian buffer impacts, the areas shall be seeded, stabilized and revegetated
upon completion of the project. Native riparian vegetation (trees and shrubs native to your geographic region) must be
reestablished in the riparian areas by the end of the growing season following completion of construction. [15A
NCAC 2B.0233] �
3. Upon completion of the project, the permittee shall schedule a site visitwith a DWR representative to confirm both
the stability of the channel relocation as well as revegetation of the Temporary Riparian Buffer impacts.
4. Pursuant to 15A NCAC 2B.0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by the NCDWR. At this time, the NCDWR has approved no sediment and
erosion control devices in Zone 1, outside of the approved project impacts, anywhere on this project. Moreover,
sediment and erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not
compromised and that discharge is released as diffuse flow.
5. All stormwater runoff shall be directed as sheetflow through stream buffers at non-erosive velocities, unless
otherwise approved by this certification. [ISA NCAC 2B.0233]
6. All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the
preconstruction contours and revegetated. Maintained buffers shall be permanently revegetated with non-woody
species by the end of the growing season following completion of construction. For the purpose of this condition,
maintained buffer areas are defined as areas within the corridor that will be subject to regular corridor maintenance
activities including mowing. The area with non-maintained buffers shall be permanently revegetated with native
woody species before the next growing season following completion of construction. [15A NCAC 2B.0233]
7. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact between
curing concrete and stream water. Water that inadvertently contacts uncured concrete shall not be discharged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills. [15A NCAC 02B.0200]
8. During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or
protected riparian buffers. [15A NCAC 02H.0506(b)(2)]
9. The dimension, pattern and profile of the stream above and below any crossings shall not be modified. Disturbed
floodplains and streams shall be restored to natural geomorphic conditions. [15A NCAC 02H.0506(b)(2)]
10. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for stream
stabilization shall be placed in stream channels in such a manner that it,does not impede aquatic life passage. [15A
NCAC 02H.0506(b)(2)] "
11. The Permittee shall ensure that the final desib drawings adhere to the permit and to the permit drawings
submitted for approval. [I SA NCAC 02H .0507 (c) and I SA NCAC 02H .0506 (b)(2) and (c)(2)]
12. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from
the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms,
cofferdams and other diversion structures shall be used to prevent excavation in flowing water. [15A NCAC
02H.0506(b)(3) and (c)(3)]
13. Heavy equipment shall be operated from the banks rather than in the stream channel in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream. [15A NCAC 02H.0506(b)(3)]
14. Al] mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. [15A NCAC
02H.0506(b)(3)]
15. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification. [15ANCACO2H.0506(b)(3)]
16. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters
is prohibited. [15A NCAC 02H.0506(b)(3)]
17. The permittee and its authorized agents shall conduct its 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 NCDWR determines that such standards or laws are not being
met (including the 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, the NCDWR may reevaluate and modify this certification. [15A
NCAC 02B.0200]
18. A copy of this Water Quality Certification shall be maintained on the construction site at all times. In addition, the
Water Quality Certification and all subsequent modifications, if any, shall be maintained with the on-site project
manager. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
19. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization, including all non-commercial borrow and waste sites associated with the project, shall be clearly marked
by highly visible fencing prior to any land disturbing activities. Impacts to areas within the fencing are prohibited unless
otherwise authorized by this certification. [15A NCAC 02H.0501 and .0502]
20. The issuance of this certification does not exempt the Permittee from complying with any and all statutes, rules,
regulations, or ordinances that may be imposed by other government agencies (i.e. local, state, and federal) having
jurisdiction, including but not limited to applicable buffer rules, stormwater management rules, soil erosion and
sedimentation control requirements, etc.
21. The Permittee shall report any violations of this certification to the Division of Water Resources within 24 hours of
discovery. [15A NCAC 02B.0506(b)(2)]
22. Upon completion of the project (including any impacts at associated borrow or waste sites), the permittee shall
complete and return the enclosed "Certification of Completion Form" to notify the NCDWR when all work included in
the 401 Certification has been completed. [15A NCAC 02H.0502(fl]
23. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this
permit without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow sites, be
located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road
construction activities. [15A NCAC 02H.0506(b)(3) and (c)(3)]
24. 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 in order to protect surface waters
standards [15A NCAC 02H.0506(b)(3) and (c)(3)]:
a. The 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. The 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 Contro! 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. The reclamation measures and implementation must comply with the reclamation in accordance with the
requirements of the Sedimentation Pollution Control Act.
25. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this
Certification. [15A NCAC 02H.0506(b)(3) and (c)(3)]
