If total wetland fills for this project (now or in the future) exceed one acre or if 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 those listed
below
1 Riprap used for bank stabilization shall be Class II as indicated in the plans with the exception of the bank stabilization
provided at the meander bend of Permit Site 2 which shall be Class I
2 The intermittent stream relocation shall be constructed as depicted on Detail A on the plans Coir fiber matting shall be
used to stabilize the stream channel and banks and properly secured to prevent movement downstream Additionally
the streambanks must be temporarily seeded with a riparian seed mix and live stakes shall be installed on the banks for
stability
3 The use of riprap above the normal high water mark shall be minimized Any nprap placed for stream stabilization shall
be placed in stream channels in such a manner that it does not impede aquatic life passage
4 The post construction removal of any temporary bridge structures must return the project site to its preconstruction
contours and elevations The impact areas shall be revegetated with appropriate native species
5 Strict adherence to the most recent version of NCDOT s Best Management Practices for Bridge Demolition and
Removal approved by the U S Army Corps of Engineers is a condition of the 401 Water Quality Certification
6 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 scourholes vegetated buffers etc ) before entering
the stream Please refer to the most current version of Stormwater Best Management Practices
7 Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft construction
methods More specifically betting or other methods of pile driving are prohibited without prior written approval from
NCDWQ first
8 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 properly disposed of
9 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by NCDWQ in this
certification
0
10 All bridge construction shall be performed from the existing bridge temporary work bridges temporary causeways or
floating or sunken barges If work conditions require barges they shall be floated into position and then sunk The
barges shall not be sunk and then dragged into position Under no circumstances should barges be dragged along the
bottom of the surface water All materials used for causeway construction must be properly removed from the -
stream upon completion
11 Heavy equipment shall be operated from the banks rather than in the stream channel in order minimize sedimentation
and reduce the introduction of other pollutants into the stream
12 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification
13 Temporary dewaternng sites must be restored to pre existing conditions unless more natural geomorphic conditions can
be provided
14 If concrete is used during construction a dry work area should be maintained to prevent direct contact between curing
concrete and stream water Water that inadvertently contacts uncured concrete should not be discharged to surface
waters due to the potential for elevated pH and possible aquatic life and fish kills
15 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 the 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

16 The dimension pattern and profile of the stream above and below the crossing should not be modified Disturbed
floodplains and streams should be restored to natural geomorphic conditions
17 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
18 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1 unless otherwise authorized
by this certification
19 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is

season following completion of construction
22 Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable If
placement of sediment and erosion control devices in wetlands and waters is unavoidable they shall be removed and
the natural grade restored within 30 days after the Division of Land Resources has released the project
23 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
