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 Pernut 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, as well as the incorrect buffer impacts issued January 10, 2008.
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 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.

8. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
9. 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.
10. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
12. The pernuttee and its authorized agents shall conduct its activities in a manner consistent with State water
quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and
any other appropriate requirements of State and Federal law. If DWQ determines that such standards or laws are not
being met (including the failure to sustain a designated or achieved use) or that State or federal law is being violated,
or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification.
13. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification..
14. A copy of this Water Quality Certification shall be posted on the construction site at all times. In addition, the
Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer
and the on-site project manager.
15. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to
areas within the fencing are prohibited unless otherwise authorized by this certification.
16. Upon completion of the project, the NCDOT Division Engineer shall complete and return the enclosed
"Certification of Completion Form" to notify DWQ when all work included in the 401 Certification has been
completed.
17. Native riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction.
18. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this.
permit without appropriate modification. Should waste or borrow sites be located in wetlands or strearns,
compensatory mitigation will be required since that is a direct impact from road construction activities.
19. The issuance of this certification does not exempt the Permittee from complying with any and all statutes, rules,
regulations, or ordinances that maybe imposed by other government agencies (i.e. local, state, and federal) having
jurisdiction, including but not limited to applicable buffer rules, stormwater management rules, soil erosion and
sedimentation control requirements, etc.
20. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of
discovery.
21. All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
