submitted for approval
4 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
5 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
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 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
15 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities unless
otherwise approved by this certification
16 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
17 Pursuant to 15A NCAC 213 0259(6) sediment and erosion control devices shall not be placed in 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
18 New roadside ditches must be in compliance with the nitrogen control and diffuse flow requirements outlined in
15A NCAC 2B 0259
19 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
20 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
21 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

methods More specifically betting or other methods of pile driving are prohibited without prior written
approval from NCDWQ
23 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by
NCDWQ in this certification
24 Bridge deck drains 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
25 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
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
