The application provides adequate assurance that the discharge of fill material into the waters of the Neuse River
Basin in conjunction with the proposed activity will not result in a violation of applicable Water Quality Standards
and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not violate the
applicable portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance
with the application and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your application dated received January
27, 2020 and revised application submitted March 12, 2020. Should your project change, you are required to notify
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 any additional
wetland impacts, or stream impacts, for this project (now or in the future) exceed one acre or 300 linear feet,
respectively, additional 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 are required to comply with all the conditions listed below. In addition, you should
obtain all other federal, state or local permits before proceeding with your project including (but not limited to)

Condition(s) of Certification:
Compensatory mitigation for impacts to 2.5 acres of riparian wetlands shall be required. We understand
that you have chosen to perform compensatory mitigation for impacts to wetlands through use of the
North Carolina Division of Mitigation Services (DMS) (formerly NCEEP), and that the DMS has agreed
to implement the mitigation for the project. The DMS has indicated in a letter dated October 3, 2019 that
they will assume responsibility for satisfying the federal Clean Water Act compensatory mitigation
requirements for the above -referenced project, in accordance with DMS's Mitigation Banking Instrument
signed June 14, 2016.
2. 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), 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.
3. Adherence to The Guidelines for Avoiding Impacts to the West Indian Manatee: Precautionary Measures
for Construction Activities in North Carolina Waters will be required throughout construction.
4. Due to the possibility that compaction and/or other site alterations might prevent the temporary wetland
impact area from re -attaining jurisdictional wetland status; the permittee shall provide an update on the
wetland areas temporarily impacted at Site 2. This update shall be conducted two growing seasons after
completion of the work at Site 2 and shall consist of photographs and a brief report on the progress of the
areas in re -attaining wetland jurisdictional status. Upon submission of this update to the NCDWR, the
permittee shall schedule an agency field meeting with the NCDWR to determine if the wetland areas
temporarily impacted by this project have re -attained jurisdictional wetland status. If the wetland areas
temporarily impacted by this project have not re -attained jurisdictional wetland status, the NCDWR shall
determine if compensatory wetland mitigation is to be required. [15A NCAC 02H.0506(c)(2)]
5. 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.
6. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
7. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization 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]
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. Unless otherwise approved in this certification, placement of culverts and other structures in open waters
and streams shall be placed 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 48 inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and
other structures including temporary erosion control measures shall not be conducted in a manner that may
result in dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and downstream of
the above structures. The applicant is required to provide evidence that the equilibrium is being
maintained if requested in writing by NCDWR. If this condition is unable to be met due to bedrock or
other limiting features encountered during construction, please contact NCDWR for guidance on how to
proceed and to determine whether or not a permit modification will be required. [I 5A NCAC
02H.0506(b)(2)]
10. If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as
closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate.

Widening the stream channel should be avoided. Stream channel widening at the inlet or outlet end of
structures typically decreases water velocity causing sediment deposition that requires increased
maintenance and disrupts aquatic life passage. [15A NCAC 02H.0506(b)(2)]
11. 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)]
12. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams shall be restored to natural geomorphic conditions. [15A NCAC
02H.0506(b)(2)]
13. 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)]
14. 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)]
15. 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. [I 5A NCAC
02H.0506(b)(2)]
16. As a condition of this 401 Water Quality Certification, the bridge demolition and construction must be
accomplished in strict compliance with the most recent version of NCDOT's Best Management Practices
for Construction and Maintenance Activities. [15A NCAC 02H .0507(d)(2) and 15A NCAC 02H
.0506(b)(5)]
17. Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft
construction methods. More specifically, jetting or other methods of pile driving are prohibited without
prior written approval from the NCDWR first. [ 15A NCAC 02H.0506(b)(2)]
18. All bridge construction shall be performed from the existing bridge, temporary work bridges, temporary
causeways, or floating or sunken barges. If work conditions require barges, they shall be floated into
position and then sunk. The barges shall not be sunk and then dragged into position. Under no
circumstances should barges be dragged along the bottom of the surface water. [I 5A NCAC 02H
.0506(b)(3)]
19. A turbidity curtain will be installed in the stream if driving or drilling activities occur within the stream
channel, on the stream bank, or within 5 feet of the top of bank. This condition can be waived with prior
approval from the NCDWR. [I 5A NCAC 02H .0506(b)(3)
20. 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. To meet the requirements of NCDOT's NPDES permit
NCS0000250, please refer to the most recent version of the North Carolina Department of Transportation
Stormwater Best Management Practices Toolbox manual for approved measures. [15A NCAC 02H

preconstruction contours and elevations. The impacted areas shall be revegetated with appropriate native
species including woody species. [15A NCAC 02H .0506(b)(2)]
22. 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]
23. Design, installation, operation, and maintenance of all sediment and erosion control measures shall be
equal to or exceed the requirements specified in the most recent version of the North Carolina Sediment
and Erosion Control Manual, or for linear transportation projects, the NCDOT Sediment and Erosion
Control Manual.
24. All devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) 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.
25. 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.
26. 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)]
27. Erosion control matting in riparian areas shall not contain a nylon mesh grid which can impinge and
entrap small animals. Matting should be secured in place by staples, stakes, or wherever possible live
stakes of native trees. Riparian areas are defined as a distance 25 feet from top of stream bank. [ 15A
NCAC 02B.0224, .0225]
28. 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 from wetlands and waters
and the natural grade restored within two (2) months of the date that the Division of Energy, Mining and
Land Resources (DEMLR) or locally delegated program has released the specific area within the project.
[15A NCAC 02H.0506(b)(3) and (c)(3)]
29. 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.
30. All stormwater runoff shall be directed as sheetflow through stream buffers at non -erosive velocities,
unless otherwise approved by this certification. (15A NCAC 2B.0233)
31. New roadside ditches that do not control for nitrogen and attenuate flow before discharging through the
riparian buffer are prohibited [15A NCAC 2B.0233(6)]
32. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless
otherwise authorized by this certification. [15A NCAC 02H.0506(b)(2)]
