* n/a = Bridge impact "allowable", no mitigation required
Total Buffer Impact for Project 4,640 square feet.
The project shall be constructed in accordance with your application dated received September 18, 2008 This
approval is 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 in your application (unless modified below)
Should your project change, you must notify the DWQ 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 in the future) exceed 1501mear 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 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 bndge
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 The post-construction removal of any temporary bridge structures must return the project site to its
preconstruction contours and elevations The impacted areas shall be revegetated with appropriate native species
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-mamtamed 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 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
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 geomorpluc conditions
10 The use of np-rap above the Normal High Water Mark shall be muumized 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
11 The Penmittee shall ensure that the final design drawings adhere to the permit 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
