I�otal Stream Impacts: 14ri linear teet
The projec[ shall be constructed in accordance with your applica[ion dated November 17, 2017. 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 Pemiit 14 issued by the Corps of Engineers. In addition,
you should acquire any other Yederal, state or Iocal permits before you proceed with your project including (but no[
limited to) Sediment and Erosion Control, NomDischarge and Water Supply Watershed regulations. This approval
will expire with the accompanying 404 pemiit.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notif'y 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 fuwre) exceed one acre, or of total
impacts to streams (now or in the fumre) eaceed 300 linear feet, compensatory mitigation may be required as
described in I SA NCAC 2H .0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
condi[ions listed in the attached certification(s) and any addi[ional conditions listed below.

Project Specific Conditions
1. Bridge demolition 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)]
2. Culverts shall be placed below the elevation of the streambed by one foot 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 down stream of the above structures. The applicant is required to provide evidence that the
equilibrium is being maintained if requested in writing by the NCDWR. If this condition is unable to be met due to
bedrock or other limiting features encountered during construction, please contact the 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)]
3. The culvert shall be designed to mimic natural stream cross section as closely as possible including 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)]
4. 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)]
5. For the 10 linear feet of streams being impacted due to site dewatering, the site shall be graded to its
preconstruction contours and revegetated with appropriate native species. [15A NCAC 02H.0506(b)(2)]
6. 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)]
7. This project has the potential to impact trout waters. No construction activities shall begin until the NCWRC
makes a determination regarding moratoria. Should the NCWRC determine that a moratorium is applicable, then the
requirements of any moratorium(s) shall be a condition of this 401 Certification. If the NCDOT does not wish to
honor the moratorium, then a written modification shall be submitted. [15A NCAC 02H .0506(b)(2) and 15A NCAC
04B.0125]
Condition(s) of Certification:
General Conditions
1. 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]
2. 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)]
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 down stream 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)] �
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 fnal 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. 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
contamination 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/flagging prior to any land disturbing
activities. Impacts to areas within the marked areas 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 NCDOT 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(�]
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 02H.0506(b)(2)]
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 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 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. 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(b)(3) and (c)(3)]
