Total Wetland Impact for Project: <0.01 acres.
The project shall be constructed in accordance with your application dated March 30, 2009 and received
by the Division of Water Quality April 6; 2009. After reviewing your application, we have decided that
these impacts are covered by General Water Quality Certification Number 3689, 3704, and 3688. This
certification corresponds to the Nationwide Permits 13, 14, and 33, respectively. 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). For this
approval to remain valid, you must adhere to the conditions listed in the attached certification.
Condition(s) of Certification:
1. The permittee shall use /Design Standards in Sensitive Watersheds/ [15A NCAC 413.0124(a)-
(e)]. Temporary cover (wheat, millet, or similar annual grain) or permanent herbaceous cover
should be planted on all bare soil within 15 days of ground disturbing activities to provide long-
term erosion control. Erosion control matting should be used in conjunction with appropriate
seeding on disturbed soils in steep slope and riparian areas. Steep slopes are defined as those
slopes graded at an angle which cannot retain vegetative cover. Matting shall be secured in place
with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue shall
not be used in riparian areas. However, due to the size of the project, NC DOT shall not be
required to meet 15A NCAC 413 .0124(a) regarding the maximum amount of uncovered acres.
2. Two copies of the final construction drawings shall be furnished to NCDWQ Central Office prior to
the pre-construction meeting. The permittee shall provide written verification that the final
construction drawings comply with the permit drawings contained in the application dated March

30, 2009. Any deviations from the approved drawings are not authorized unless approved by the
NC Division of Water Quality.
3. The outside buffer, wetland of 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.
4. Bridge deck drains should 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
5. No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter
surface waters. This water shall be captured, treated, and disposed of properly.
6. For projects impacting waters classified by the NC Environmental Management Commission as
Trout Jr), High Quality Waters (HQW), or Water Supply I or II (WSI, WSII) stormwater shall be
directed to vegetated buffer areas, grass-lined ditches or other means appropriate to the site for the
purpose of pre-treating storm water runoff prior to discharging directly into streams. Mowing of
existing vegetated buffers is strongly discouraged.
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. 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.
9. 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.
10. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit
drawings submitted for approval.
11. 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.
12. 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.
13. No rock, sand or other materials shall be dredged from the stream channel except where authorized
by this certification.
14. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent
to surface waters is prohibited.
15. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless
otherwise authorized by this certification..

16. 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.
17. 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.
18. The Permittee shall report any violations of this certification to the Division of Water Quality
within 24 hours of discovery.
19. 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.
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 to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699. This certification and its
conditions are final and binding unless you ask for a.hearing. This letter completes the review of the
Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please
contact Amy Euliss at [phone].
