regulations This approval will expue with the accompanying 404 permit
l

1 The issuance of this certification does not exempt the Perm►ttee from complying with any and all statutes rules regulations or
ordinances that may be imposed by other government agencies (i a local state and federal) having jurisdiction including but not
limited to applicable buffer rules stormwater management rules soil erosion and sedimentation control requirements etc
2 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 DWQ 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 DWQ may reevaluate and modify this certification
3 The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings submitted for approval
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 downstream of the
above structures The applicant is required to provide evidence that the equilibrium is being maintained if requested in writing by
NCDWQ If this condition is unable to be met due to bedrock or other limiting features encountered during construction please
contact NCDWQ for guidance on how to proceed and to determine whether or not a permit modification will be required
5 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
6 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
7 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
8 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
9 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
10 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
11 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
12 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification
13 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited
14 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1 unless otherwise authorized by this
certification
15 The outside buffer wetland or water boundary located within the construction corridor approved by this certification 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
16 Native riparian vegetation (ex list trees and shrubs native to your geographic region) must be reestablished within the
construction limits of the project by the end of the growing season following completion of construction

Page 3 of 5
17 There shall be no excavation from or waste disposal into .jurisdictional wetlands or waters associated with this certification
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
18 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
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
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
19 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
20 Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life
passage Bioengineering boulders or structures should be properly designed sized and installed
21 New roadside ditches must be in compliance with the nitrogen control and diffuse flow requirements outlined in 15A NCAC 2B
0233
22 Pursuant to NCAC15A 2B 0233(6) sediment and erosion control devices shall not be placed in Zone 1 of any Neuse Buffer
without prior approval by the NCDWQ At this time the 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
23 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 DOT 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
24 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities unless otherwise approved
by this certification
25 The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of discovery
26 Upon completion of the project (including any impacts at associated borrow or waste site) the NCDOT Division Engineer shall
complete and return the enclosed Certification of Completion Form to notify DWQ when all work included in the 401
Certification has been completed
27 A copy of this Water Quality Certification shall be maintained on site at 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
