This approval is only valid for the purpose and design that you submitted in your application dated received April
29,2022. Should your project change,you are required to 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 any additional wetland impacts,or stream impacts,for this
project(now or in the future)exceed one acre or 150 linear feet,respectively,additional compensatory mitigation
may be required as described in 15A NCAC 2H.0506(h)(6)and(7).
For this approval to remain valid,you are required to comply with all the conditions listed below. In addition,you
should obtain all other federal, state or local permits before proceeding with your project including(but not limited
to)Sediment and Erosion control,Coastal Stormwater,Non-discharge and Water Supply watershed regulations.
This Certification shall expire on the same day as the expiration date of the corresponding Corps of Engineers
Permit.
This Water Quality Certification neither grants nor affirms any property right,license,or privilege in any lands
or waters,or any right of use in any waters. This Water Quality Certification does not authorize any person to
interfere with the riparian rights,littoral rights,or water use rights of any other person and does not create any
prescriptive right or any right of priority regarding any usage of water. This Water Quality Certification shall not be
interposed as a defense in any action respecting the determination of riparian or littoral rights or other rights to water
use. No consumptive user is deemed by virtue of this Water Quality Certification to possess any prescriptive or
other right of priority with respect to any other consumptive user regardless of the quantity of the withdrawal or the
date on which the withdrawal was initiated or expanded. Upon the presentation of proper credentials,the
Division may inspect the property.
Conditions of Certification:
1. When final design plans are completed for Phase II,a modification to the 401 Water Quality Certification shall
be submitted to the NC Division of Water Resources. Final designs shall reflect all appropriate avoidance,
minimization,and mitigation for impacts to wetlands,streams,and other surface waters. No construction activities
that impact any wetlands,streams,surface waters,or buffers located in Phase II shall begin until after the permittee
applies for,and receives a written modification of the 401 Water Quality Certification from the NC Division of
Water Resources.
2. Compensatory mitigation for impacts to 0.25 acres of wetlands is required. We understand that you have chosen
to perform compensatory mitigation for impacts to wetlands through the North Carolina Division of Mitigation
Services(DMS)(formerly NCEEP),and that the DMS has agreed to implement the mitigation for the project. DMS
has indicated in a letter dated March 30,2022 that they will assume responsibility for satisfying the federal Clean
Water Act compensatory mitigation requirements for the above-referenced project,in accordance with DMS's
Mitigation Banking Instrument signed July 28,2010.
3.All portions of the proposed project draining to 303(d)listed impaired watersheds shall be designed,constructed,
and operated with sediment and erosion control measures that meet Design Standards in Sensitive Watersheds(15A
NCAC 4B .0124). However,due to the size of the project,NC DOT shall not be required to meet 15A NCAC
4B .0124(a)regarding the maximum amount of uncovered acres. Stormwater shall be treated using appropriate best
management practices(e.g.,vegetated conveyances,constructed wetlands,detention ponds,etc.)to the maximum
extent practicable,prior to discharging to surface waters.
4.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 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)]

5.If multiple pipes or barrels are required,they 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 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 all 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)]
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. 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]
10.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)]
11.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)]
12.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)]
13.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)]
14.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)]
15.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)]
16.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)]
17.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)]
18.Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited. [15A NCAC 02H.0506(b)(3)]
19.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)]

20.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]
21.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)]
22.The outside buffer,wetland or water boundary located within the construction corridor approved by this
authorization,including all non-commercial borrow and waste sites associated with the project, 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]
23.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.
24.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)]
25.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)]
26.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)]
27.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
