Total Stream Impact for Project: 143 linear feet.
The project shall be constructed in accordance with your application dated July 31, 2015. After reviewing your
application, we have decided that these impacts are covered by General Water Quality Certification Number 3886
which correspond to the Nationwide/General Permits 14 issued by the Corps of Engineers. 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 li»ear feet, compensatory mitigation may be required as
described in 15A NCAC 2H .0506 (h) (6) and (7). 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. As a condition of this 401 Water Quality Certification, the 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. NCDOT shall be in compliance with the NCS000250 issued to the NCDOT, including the applicable
requirements of the NCGO 10000. Please note the extra protections for the sensitive watersheds as Mill
Creek is Trout waters and drains to the South Fork New River which is classified as High Quality Waters
(HQW). [15A NCAC 4B.0124(a)-(e)]
3. This project has the potential to impact trout waters or other aquatic species of concern. 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. [f the NCDOT does not wish to honor the moratorium, then a written
modification shall be submitted.
4. For the 81 linear feet of streams 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)]
5. The culvert shall be designed to mimic natural stream cross section as closely as possible. Widening the
stream channel should be avoided. [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 responsib!e 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. 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)]
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.0200J

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. [ I SA 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. 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)]
8. 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)]
9. 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)]
10. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited. [15A NCAC 02H.0506(b)(3)]
1 l. 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
C?ean Water Act) and any other appropriate requirements of StatP and Federal law. If the ?`1CDWR
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]
12. 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)]
13. 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)]
14. 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]
15. 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.
16. The Permittee shall report any violations of this certitication to the Division of Water Resources within
24 hours of discovery. [ l5A NCAC 02B.0506(b)(2)]

17. 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(fl]
18. 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)(3)]
19. 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)]
20. 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.
