* n/a =Bridge impact allowable; no mitigation.
Total Buffer Impact for Project: 3,918 square feet.
The project shall be constructed in accordance with your application dated received April 1, 2008 and additional
information received April 10, 2008. This approval is also valid for the Tar-PamlicoRiparian 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 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 150 linear feet, compensatory mitigation maybe 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 Authorization:
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.

before entering the stream. Please refer to the most current version of Stormwater Best Management Practices.
3. 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.
4. 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.
5. Pursuant to NCACISA 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.
6. All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
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
floodplains and streams shall be restored to natural geomorphic conditions.
10. 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.
11. The Pernuttee 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 miiumize
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.
