* n/a =Total for Site is less than 1/3 acre and 1501inear feet of impact, no mitigation required
Total Buffer Impact for Project: '7251 square feet.
The project shall be constructed in accordance with your application dated received June 15, 2006.. After reviewing
your application, we have decided that these impacts are covered by General Water Quality Certification Number
3494. This certification corresponds to the Nationwide Permit 3 issued by the. Corps of Engineers.. This approval is
also valid for the Tar-Pamlico Riparian Buffer Rules (15A NCAC 2B.0250). 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.

Alan W. Klimek, P.E. Director
Division of Water Quality
1. All stormwater runoff shall be duected as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
2. All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the.
preconstruction contours and revegated. 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.
3. Pursuant to NCAC 15A 2B.0259(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Tar-Pamlico 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.
4. 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..
5. 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.
6. The permittee will need to adhere to all appropriate in-water work moratoriums (including the use of pile. driving
or vibration techniques) prescribed by the NC Wildlife Resources Commission, the US Fish and Wildlife Service,
and National Marine Fisheries Service.. No in-water work is permitted between February 15 and June 15 of any
year, without prior approval from the NC Division of Water Quality and the NC Wildlife Resources Commission.
In addition, the permittee shall conform with the NCDOT policy entitled "Stream Crossing Guidelines for
Anadromous Fish Passage (May 12, 1997) at all times.
7. If concrete is used during construction, a dry work area should be maintained to prevent direct contact between
curing concrete and stream water. Water that inadvertently contacts uncured concrete should 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 should not be modified.
Disturbed floodplains and streams should 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. 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.
12. 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.

13. 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.
14. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
15. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
16. 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.
17. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification..
18. 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.
19. 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.
20. Upon completion of the project, the NCDOT Division Engineer (or whomever is the authorized agent if a non-
DOT project) shall complete and return the enclosed "Certification of Completion Form" to notify DWQ when all
work included in the 401 Certification has been completed..
21. Native riparian vegetation must be reestablished within the construction limits. of the project by the end of the
growing season following completion of construction.
22. 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. be located in wetlands or streams,
compensatory mitigation will be required since that is a direct impact from road construction activities.
23. 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.
