The project shall be constructed m accordance with your application dated received October 16 2012 After
reviewing your application we have decided that these impacts are covered by General Water Quality Certification
Number 3883 This certification corresponds to the Nationwide Permit 3 issued by the Corps of Engineers This
approval is also valid for the Tar Pamlico Riparian Buffer Rules(15A NCAC 2B 0259) 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 m your application(unless modified below)
Should your project change you must notify the NCDWQ 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 m the future)exceed 150 linear feet compensatory mitigation may be required as
described m 15A NCAC 2H 0506(h)(6)and(7) Additional buffer impacts may require compensatory mitigation
as described in 15A NCAC 2B 0260(9) For this approval to remain valid you must adhere to the conditions listed
m the attached certification and any additional conditions listed below
Conditions of Certification
1 Strict adherence to the most recent version of NCDOT s Best Management Practices For Bridge Demolition and
Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality Certification
2 Bridge deck drams shall not discharge directly into the stream Stormwater shall be directed across the bridge and
pre treated through site appropriate means(grassed swales pre formed scour holes vegetated buffers etc)before
entering the stream Please refer to the most current version of Stormwater Best Management Practices
3 Bridge piles and bents shall be constructed using driven piles(hammer or vibratory)or drilled shaft construction
methods More specifically jetting or other methods of pile driving are prohibited without prior written approval from
NCDWQ first
4 No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter surface waters This
water shall be captured treated and disposed of properly
5 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by NCDWQ in
this certification
6 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities unless
otherwise approved by this certification
7 All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the
preconstruction contours and revegetated Maintained buffers shall be permanently revegetated with non woody
species by the end of the growing season following completion of construction For the purpose of this condition
maintained buffer areas are defined as areas within the transportation corridor that will be subject to regular NCDOT
maintenance activities including mowing The area with non maintained buffers shall be permanently revegetated with
native woody species before the next growing season following completion of construction
8 Pursuant to 15A NCAC 2B 0259(6) sediment and erosion control devices shall not be placed m Zone 1 of any
Tar Pamlico Buffer without prior approval by NCDWQ At this time NCDWQ has approved no sediment and erosion
control devices in Zone 1 outside of the approved project impacts anywhere on this project Moreover sediment and
erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not compromised and that
discharge is released as diffuse flow
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 madvertently contacts uncured concrete shall not be discharged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills
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

11 The dimension pattern and profile of the stream above and below the crossing shall not be modified Disturbed
floodplams and streams shall be restored to natural geomorphic conditions
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 m stream channels in such a manner that it does not impede aquatic life passage
13 The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval
14 All work m or adjacent to stream waters shall be conducted m 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
15 Heavy equipment shall be operated from the banks rather than in the stream channel in order to mmimize
sedimentation and reduce the introduction of other pollutants into the stream
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
17 No rock sand or other materials shall be dredged from the stream channel except where authorized by this
certification
18 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited
19 The permittee and its authorized agents shall conduct its activities m 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 NCDWQ 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 NCDWQ may reevaluate and modify this certification
20 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1 unless otherwise
authorized by this certification
21 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 Engmeer
and the on site project manager
22 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 disturbmg activities Impacts to areas
within the fencing are prohibited unless otherwise authorized by this certification
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 Quality within 24 hours of
discovery
25 Upon completion of the project(mcludmg any impacts at associated borrow or waste sites) the NCDOT Division
Engineer shall complete and return the enclosed Certification of Completion Form to notify NCDWQ when all work
included in the 401 Certification has been completed

riparian areas within the construction limits of the project by the end of the growing season following completion of
construction
27 Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this
Certification

28 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
29 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
