Total Buffer Impact for Project: 13271 square feet.
The project shall be constructed in accordance with your application dated received July 16, 2010, with additional
information dated received September 24, 2010, October 20, 2010, November 1, 2010, and February 10, 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. This approval is also valid for the Jordan Lake Riparian Buffer Rules (15A NCAC 2B .0267). 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 .0268. For this approval to remain valid, you must adhere to the conditions listed in the attached
certification(s) and any additional conditions listed below.
Condition(s) of Certification:
Project Specific Conditions
1. The permittee shall visually monitor the relocated channel and the existing stream every six months to
assess and ensure complete stabilization of the relocated stream segment. The monitoring shall be
conducted every six months for a minimum of 2 years after project completion. Pictures of the channel
shall be submitted to the Winston Salem Regional Office, Division of Water Quality, following each
inspection.
2. Compensatory mitigation for impacts to 978 square feet of protected riparian buffers in Zone 1 (2934
square feet of buffer mitigation) and 2782 square feet of protected riparian buffers in Zone 2 shall be
required (4173 square feet of buffer mitigation). We understand that you have chosen to perform
compensatory mitigation for impacts to protected buffers through use of the North Carolina Ecosystem
Enhancement Program (EEP). Mitigation for unavoidable impacts to Jordan Lake Riparian Buffers shall
be provided in the Cape Fear River Basin and done in accordance with 15A NCAC 2B.0267. EEP has
indicated in a letter dated August 31, 2010 that they will assume responsibility for satisfying the
compensatory mitigation requirements for the above-referenced project.
3. All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities,
unless otherwise approved by this certification.
4. 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 NCDOT 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.
5. Pursuant to NCAC15A 2B .0267, sediment and erosion control devices shall not be placed in Zone 1 of
any Jordan Buffer without prior approval by NCDWQ. At this time, 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.
6. 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.
General Conditions
7. Native riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
8. 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.
9. 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.
10. 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 first.
11. 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.
12. 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.
13. 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.
14. 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.
15. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
16. 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.
17. 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.
18. 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.
19. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
20. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited.
21. State or federal law is being violated, or that further conditions are necessary to assure compliance,
NCDWQ may reevaluate and modify this certification
22. 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.
23. 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.
24. The Permittee shall report any violations of this certification to the Division of Water Quality within 24
hours of discovery.
If you wish to contest any statement in the attached Certification you must file a petition for an administrative
hearing. You may obtain the petition form from the office of Administrative hearings.. You must file the petition
