3 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
4 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification
5 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
6 Pursuant to NCAC15A 2B 0259(6), sediment and erosion control devices shall not be placed in Zone 1 of any Tar-
Pamlico 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 mnpacts, 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
7 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
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 The use of np-rap above the Normal High Water Mark shall be mrm sized Any np-rap placed for stream
stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage
I1 The Permrttee shall ensure that the final design drawings adhere to the perrrut and to the permit drawings
submitted for approval
12 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
13 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
14 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
15 No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification
16 Discharging hydroseed rmxtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited
