Total Buffer Impact for Project: 2,000 square feet.
The project shall be constructed in accordance with your application dated received January 22, 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 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 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. 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.
3. For any streams being impacted due to site dewatering activties, the site shall be graded to its preconstruction
contours and 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-maintained buffers shall be permanently revegetated,
with native woody species before the next growing season following completion of construction.
6. Pursuant to NCACISA 2B.0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse 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
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 Permittee 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.
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 mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
17. A copy of this Water Quality Certification shall be maintained on site at 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.
18. 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.
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. Upon completion of the project (including any impacts at associated borrow or waste site), 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.
22. Native riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction.
23. 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, or access roads to waste or borrow sites, be
located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road
construction activities.
