Total Stream Impact for Project: 25 linear feet.
The project shall be constructed in accordance with your application dated received August 2, 2019. After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Number 4132. 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 150 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
August 2, 2019, the pipe replacement will not meet the burial requirement of GC 4132 of 1 foot. The
proposed culvert extension will be connected to the existing pipe and will be on a 1.25 percent slope,
resulting in the outlet being perched approximately 0.5' above the natural streambed elevation. The plan also
includes two 18" RCP (one at 24' and one at 40') within the lateral ditches and connecting to the 24" RCP
by a 4'X4'X4' junction box. The culvert shall be installed per the proposed plan (dated 08/02/2019) and 5
linear feet of rip rap and flowable fill at the downstream pipe outfall. If any compliance issues with the
culvert occur, DWR may require DOT to submit a modification of this culvert design. [15A 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)]
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. [I 5A NCAC 02H.0506(b)(3)]
DocuSign Envelope ID: 36107728-A5CC-4F3C-B926-613F6A981994
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 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.0231(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. [ I 5A 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.
DocuSign Envelope ID: 36107728-A5CC-4F3C-B926-613F6A981994
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)]
