The project shall be constructed in accordance with your application dated received March 20, 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. 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 if total impacts
to streams (now or in the future) exceed 150 linear 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.
Conditions of Certification:
1. In order to allow maximum flow in Third Creek, only one causeway will be allowed to be in place at any
given time.
2. 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 re-vegetated with appropriate native
woody species.
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. 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.
5. 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 modification to this certification will be required.
6. 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.

7. 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.
8. 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 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

21. The permittee 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.
22. The outside buffer, wetland or water boundary located within the construction corridor approved by this
certification 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.
23. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless
otherwise authorized by this certification.
24. The issuance of this certification does not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances that may be 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.
25. Native riparian vegetation must be re-established within the construction limits of the project by the end of
the growing season following completion of construction.
26. Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices in order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Sediment and
Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures
must be such that they equal, or exceed, the requirements specified in the most recent version of
the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all
construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or
leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Surface Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance
with the requirements of the Sedimentation Pollution Control Act.
27. The Permittee shall report any violations of this certification to the Division of Water Quality within 24
hours of discovery.
28. 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.
29. 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.
