The application provides adequate assurance that the discharge of fill material into the waters of the Cape River
Basin in conjunction with the proposed development will not result in a violation of applicable Water Quality
Standards and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not violate
the applicable portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance
with the application and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your application dated March 25, 2009,
with additional information received April 14, 2009, May 4, 2009, and July 29, 2009. Should your project change,
you are required to 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 any additional wetland impacts, or stream impacts, for this project (now or in the future) exceed one
acre or 150 linear feet, respectively, additional compensatory mitigation may be required as described in 15A NCAC
2H .0506 (h) (6) and (7). For this approval to remain valid, you are required to comply with all the conditions listed
below. In addition, you should obtain all other federal, state or local permits before proceeding with your project
including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge and Water Supply
watershed regulations. This Certification shall expire on the same day as the expiration date of the corresponding
Corps of Engineers Permit.
Condition(s) of Certification:
Project Specific Conditions
1. Compensatory mitigation for 423 linear feet of impact to streams is required. We understand that you have
chosen to perform compensatory mitigation for impacts to streams through the North Carolina Ecosystem
Enhancement Program (EEP), and that the EEP has agreed to implement the mitigation for the project. EEP
has indicated in a letter dated April 30, 2009 that they will assume responsibility for satisfying the federal
Clean Water Act compensatory mitigation requirements for the above-referenced project, in accordance with
the Tri-Party MOA signed on July 22, 2003 and the Dual-Party MOA signed on April 12, 2004.
2. At site 3, channel relocations shall be completed and stabilized, and approved on site by DWQ staff, prior to
diverting water into the new channel. If matting is used on stream banks, it shall be limited to coir-fiber.
Vegetation used for bank stabilization shall be limited to native riparian vegetation, and should include
establishment of a vegetated buffer on both sides of the relocated channel to the maximum extent practical.
Also, rip-rap is allowable on the stream banks to the extent requested in the permit application, however it
shall not be placed in the stream bed.
General Conditions
3. Unless otherwise approved in this certification, placement of culverts and other structures in waters,
streams, and wetlands 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 NCD WQ. 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.
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 the rip rap does not impede aquatic
life passage.
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. 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.
7. 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.
8. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
9. 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.
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. 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 NCDWQ 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,
NCDWQ may reevaluate and modify this certification.
15. 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.
16. 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.
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. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify
NCDWQ when all work included in the 401 Certification has been completed.
20. Native riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
21. 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.
22. 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.
23. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved
by this Certification.
Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal
and/or civil penalties. This Certification shall become null and void unless the above conditions are made
conditions of the Federal 404 and/or Coastal Area Management Act Permit. This Certification shall expire upon the
expiration of the 404 or CAMA permit.
If this Certification is unacceptable to you have the right to an adjudicatory hearing upon written request within sixty
(60) days following receipt of this Certification. This request must be in the form of a written petition conforming to
Chapter I50B of the North Carolina General Statutes and filed with the Office of Administrative Hearings, 6714
Mail Service Center, Raleigh, N.C. 27699-6714. If modifications are made to an original Certification, you have
the right to an adjudicatory hearing on the modifications upon written request within sixty (60) days following
receipt of the Certification. Unless such demands are made, this Certification shall be final and binding.
