The project shall be constructed in accordance with your application dated received November 3, 2016. After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Number 3886. 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 .02B .0233). In addition, you should acquire
any other federal, state or local 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 150 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 02B. 0233. For this approval to remain valid, you must adhere to the conditions listed in
the attached certification(s) and any additional conditions listed below.
Condition(s) of Certification: Project Specific Conditions
1. All stormwater runoff shall be directed as sheetflow through stream buffers at non-erosive velocities,
unless otherwise approved by this certification. (15A NCAC .02B .0267)
2. 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 transportation corridor
that will be subject to regular NCDOT 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 .02B .0267) ,
3. Pursuant to 15A NCAC 02B .0233(6), sediment and erosion control devices shall not be placed in Zone 1
of any 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.
4. 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)]
5. Culvert barrels 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)]
6. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that
precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized
and installed. [15A NCAC 02H.0506(b)(2)]
7. For the 581inear feet of stream being impacted due to site dewatering activities, the site shall be graded to
its preconstruction contours and revegetated with appropriate native species. [15A NCAC 02H.0506(b)(2)]
8. The stream channel shall be excavated no deeper than the natural bed material of the stream, to the
maximum extent practicable. Efforts must be made to minimize impacts to the stream banks, as well as to
vegetation responsible for maintaining the stream bank stability. Any applicable riparian buffer impact for
access to stream channel shall be temporary and be revegetated with native riparian species. [15A NCAC
02H.0506(b)(2)]
9. Stormwater shall be directed to vegetated buffer areas, grass-lined ditches or other means appropriate to
the site for the purpose of pre-treating storm water runoff prior to discharging directly into streams.
Mowing of existing vegetated buffers is strongly discouraged.
10. NCDOT shall be in compliance with the NPDES Permit NCS000250 issued to the NCDOT, including the
applicable requirements of General Permit NCGO1000 for Construction Activities.
11. Tall :fescue shall not be used in tfie establishment of temporary or permanent groundcover within riparian
areas. For the establishment of permanent herbaceous cover, erosion control matting shall be used in
conjunction with an appropriate native seed mix on disturbed soils within the riparian area and on
disturbed steep slopes with the following exception. Erosion control matting is not necessary if the area is
contained by perimeter erosion control devices such as silt fence, temporary sediment ditches, basins, etc.
Matting should be secured in place with staples, stakes, or wherever possible, live stakes of native trees.
Erosion control matting placed in riparian areas shall not contain a nylon mesh grid,. which can impinge
and entrap small animals. For the establishment of temporary groundcover within riparian areas,
hydroseeding along with wood or cellulose based hydro mulch applied from a fertilizer- and limestone-
free tank is allowable at the appropriate rate in conjunction with the erosion control measures.
Discharging hydroseed mixtures and wood or cellulose mulch into surface waters in prohibited. Riparian
areas are defined as a distance 25 feet landward from top of stream bank.
General Conditions
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.
[15A NCAC 02H.0506(b)(2)]
2. 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]
3. 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)]
4. 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)]
5. 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)]
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
(�)(2)l ,
7. 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)]
8. 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)]
9. All mechanized equipment operated near surface waters must be regularly inspected and maintained to
prevent contacnination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
[15A NCAC 02H.0506(b)(3)]
10. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification. [15A NCAC 02H.0506(b)(3)]
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited. [15A NCAC 02H.0506(b)(3)]
12. 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]
13. 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)]
14. 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 Division Engineer and the on-site project manager. [15A NCAC 02H .0507(c) and 15A NCAC 02H
.0506 (b)(2) and (c)(2)]
15. 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]
16. 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.
17. 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)]
18. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDaT
Division Engineer (or appointee) 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] �
19. Native riparian vegetation must be reestablished in the riparian areas within the construction limits of the
project by the end of the growing season following completion of construction. [15A NCAC
02B.0267(10)]
20. 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)]
21. 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 Contro! Planning and Desrgn Manual.
b. T'he 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) projecu, 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 Caro[ina Su{jace
Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance
with the requirements of the Sedimentation Pollution Control Act.
22. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise
approved by this Certification. [15A NCAC 02H.0506(bx3) and (c)(3)]
