The project shall be constructed in accordance with your original application dated received March 8, 2006, your
modification request dated received April 11, 2007, and re-issuance request dated received January 9, 2008. After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Number 3704. This certification corresponds to the Nationwide Permit 14 issued by the Corps of Engineers. This
approval is also valid for the Neuse Riparian Buffer Rules (15A NCAC 2B .0233). 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 certification replaces the previous versions issued Apri124, 2006 and April 17,
2007.
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 1501inear 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 as well as those listed below.
Conditions of Certification:
1. Placement of culverts and other structures in waters, streams, and wetlands shall be placed below the elevation of
the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert
diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life.
Design and placement of culverts and other structures including temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or banks, adjacent to or
upstream and down stream of the above structures. The applicant is required to provide evidence that the
equilibrium is being maintained if requested in writing by DWQ. If this condition is unable to be met due to
bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on
how to proceed and to determine whether or not a permit modification will be required.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
