Dear Mr. Willis
You have our approval, in accordance with the conditions listed below, for the following impacts for the purpose of
the replacement of Bridge No. 12 and Bridge No. 25 over Ahoskie Creek and associated overflow in Hertford
County:
Wetland Impacts in the Chowan River Basin

Total 0.05 0.21
Net Total 0.26 <0.01*
*impacts due to bridge pilings
The project shall be constructed in accordance with your application dated received March 1, 2011. After reviewing
your application, we have decided that these impacts are covered by General Water Quality Certification Number
3820. 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 NCDWQ 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 may be required as described in 15A NCAC 2H .0506 (h) (6) and (7).
Additional buffer impacts may require compensatory mitigation as described in 15A NCAC 2B.0200.
For this approval to remain valid, you must adhere to the conditions listed in the attached certification.

Condition(s) of Certification:
1. 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.
2. 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 NCDWQ 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,
NCDWQ may reevaluate and modify this certification.
3. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
4. 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.
5. 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.
6. 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.
7. 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.
& The post-construction removal of any temporary bridge structures must return the project site to its
preconstntction contours and elevations. The impacted areas shall be revegetated with appropriate native
species.
9. Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft
construction methods. More specifically, jetting or other methods of pile driving are prohibited without
prior written approval from NCDWQ.
10. Bridge deck drains shall not discharge directly into the stream. Stormwater shall 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.

11. 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.
12. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless
otherwise authorized by this certification.
13. 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.
14. 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.
15. Where placement of sediment and erosion control devices in wetlands and/or waters is unavoidable, they
shall be removed and the natural grade restored upon completion of the project.
16. Native riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
17. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited.
18. The Permittee shall report any violations of this certification to the Division of Water Quality within 24
hours of discovery.
19. A copy of this Water Quality Certification shall be maintained 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.
20. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify
NCDWQ when all work included in the 401 Certification has been completed.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms

This letter completes the review of the Division of Water Quality under Section 401 of the CleanWater Act. If you
have any questions, please contact Garcv Ward at [phone].
