The project shall be constructed in accordance with your application dated received March 5, 2007 and addendum
received March 12, 2007. After reviewing your application, we have decided that these impacts are covered by
General Water Quality Certification Numbers 3494 and 3404. This certification corresponds to the Nationwide
Permit 3 and General Permit 31 issued by the Corps of Engineers. This approval is also valid for the Tar-Pamlico
Riparian 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 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 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. For the onsite wetland restoration site, NCDOT shall monitor vegetation success by visual observation and photo
documentation and will submit an annual report to DWQ. DOT shall monitor the site for a minimum of three years
or until the site is deemed successful in writing by DWQ.
2. Upon success of the onsite wetland restoration site, NCDOT will have 0.4 acres of riparian wetland restoration
credit available for use in the eight digit HUC 03020101.
3. 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.
4. Bridge deck drains should not discharge directly into the stream. Stormwater should be directed across. the
bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated buffers,
etc.) before entering the stream. Please refer to the most current version of Stormwater Best Management Practices.
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 deternune whether or not a permit modification will be required.
6. Riprap should 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.
7. For the 1091inear feet of streams being impacted due to site dewatering activties, the site shall be graded to its
preconstruction contours and revegetated with appropriate native species.
8. In accordance with commitments made in your application, due to potential sedimentation concerns resulting
from demolition of the bridges, where it is possible to do so, turbidity curtains will be used to minimize
sedimentation in the stream.

22. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification..
23. 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.
24. 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.
25. 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.
26. Native riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction.
27. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this
perrnit without appropriate modification. Should 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.
28. 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.
29. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by
this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they
shall be removed and the natural grade restored upon completion of the project.
