APPROVAL of 401 WATER QUALITY CERTIFICATION with ADDITIONAL CONDITIONS
Mr. Clay Willis
NCDOT, Division 1
113 Airport Drive Suite 100
Edenton, NC 27932
Dear Mr. Willis:
You have our approval, in accordance with the attached conditions and those listed below, for the following
impacts:
Site Wetland
Fill
acres Wetland
Hand Clearing
acres
1 0.006
2 0.003
3 0.185
4 0.048
Total 024 0.24
Net Total Impacts 0.48
The project shall be constructed in accordance with your application dated received October 15, 2009 for
the purpose of replacing bridge number 32 over Trotman Creek on SR 1100 (Carters Road) in Gates
County. 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 issued by the US Army Corps of Engineers.
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 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.
1. 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.
2. 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.
3. 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.
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. 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.
6. 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.
7. The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings
submitted for approval.
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.
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. 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 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.

14. Native riparian vegetation (ex. list trees and shrubs native to your geographic region) must be
reestablished within the construction limits of the project by the end of the growing season following
completion of construction.
15. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated
with this certification 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.
16. 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.
17. 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.
18. 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 revegetated with appropriate
native species.
19. 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.
20. 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.
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.
?2. 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.
