The project shall be constructed in accordance with your application dated received March 12, 2010 and
amendments dated received May 4, 2010 and May 24, 2010. After reviewing your application, we have decided that
these impacts are covered by General Water Quality Certification 3704. This certification corresponds to the
General Permit 31 issued by the Corps of Engineers. This approval is also valid for the Neuse Riparian Buffer Rules
(15A NCAC 2B .0233). 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 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 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 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.
3. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of
discovery.
4. The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings
submitted for approval.
5. 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.
6. 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.
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. Unless otherwise approved in this certification, placement of culverts and other structures in open waters and
streams 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 NCDWQ. If this condition is unable to be met due to bedrock or other limiting features encountered
during construction, please contact NCDWQ for guidance on how to proceed and to determine whether or not a
permit modification will be required.
9. 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.
10. 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.
11. 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.
12. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
13. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
14. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification.

15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
21. New roadside ditches must be in compliance with the nitrogen control and diffuse flow requirements outlined in
15A NCAC 2B .0233.
22. Pursuant to NCAC15A 2B .0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by the NCDWQ. At this time, the NCDWQ has approved no sediment and
erosion control devices in Zone I, 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.
23. All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the
preconstruction contours and revegetated. 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.
24. 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.

25. 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.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
