Total Stream Impact for Project: 25 linear feet.
The project shall be constructed in accordance with your application dated received June 26, 2019. After
reviewing your application, we have decided that these impacts are covered by General Water Quality
Certification Number 4085. This certification corresponds to the Nationwide Permit 3 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 300 linear 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 and any
additional conditions listed below.

Conditions of Certification:
Project Specific Conditions
Due to the existing geomorphological conditions at the site as described in your application
received on June 26, 2019, the pipe replacement will not meet the burial requirement of GC
4085 of 1 foot. The proposed culvert will be buried 1 foot at the inlet invert and will be on a 2
percent slope, resulting in the outlet being pipe being approximately on grade. The culvert
shall be installed per the proposed plan (dated 6/25/2019) and 10 linear feet of rip rap and
flowable fill at the downstream pipe outlet. There will be an additional 15 feet of temporary
stream impact due to site dewatering. If any compliance issues with the culvert occur, DWR
may require DOT to submit a modification of this culvert design. [I 5A NCAC
02H.0506(b)(2)]
General Conditions
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 0213.0200]
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 (c)(2)]
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)].
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)]
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)]
DocuSign Envelope ID: E4AFC5AE-53AE-494B-9E8B-52FA9E6832F1
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. [I 5A 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
NCDOT Division Engineer 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(f)]
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.023 1 (a)(6)]
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)]
DocuSign Envelope ID: E4AFC5AE-53AE-494B-9E8B-52FA9E6832F1
21 Erosion and sediment control practices must be in full compliance with all specifications
