The application provides adequate assurance that the discharge of fill material into the waters of the Cape Fear
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 received
December 1, 2009, with additional information received January 13, 2010, and February 12, 2010. Should your
project change, you are required to notify the NCD WQ 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). Additional buffer impacts may require compensatory mitigation as described
in 15A NCAC 02B.0268. 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. Modifications to this permit will be subject to Jordan Lake Buffer Rules as described in 15A NCAC 02B
.0268 and DWQ's Intermittent Stream Policy effective October 16, 2009.
2. The NCDOT Division Environmental Officer or Environmental Assistant will conduct a pre-construction
meeting with all appropriate staff to ensure that the project supervisor and essential staff understand the
potential issues with stream and pipe alignment at the permitted site. NCD WQ staff shall be invited to the
pre-construction meeting.
3. Compensatory mitigation for 856 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 August 18, 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.
4. All channel relocations will be constructed in a dry work area and stabilized before stream flows are
diverted. Channel relocations will be completed and stabilized, and must be approved on site by NCDWQ
staff, prior to diverting water into the new channel. Whenever possible, channel relocations shall be allowed
to stabilize for an entire growing season. Stream banks shall be matted with coir-fiber matting, unless rip
rap is approved. Rip-rap is allowed on the banks and in the stream bed for stream channel relocations at Site
1, 2, 3 and 5. Additional rip-rap may be allowed if it is necessary to maintain the physical integrity of the
stream, but the applicant must provide written justification and any calculations used to determine the extent
of rip-rap coverage requested. 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.
5. Three, one-foot sills shall be placed in the culvert at approximately 200' apart at site 5.
6. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that
precludes aquatic life passage. Any riprap placed below the normal high water mark in the channel bottom
shall be keyed into the stream bed and banks. Bioengineering boulders or structures should be properly
designed, sized and installed.
7. 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.
8. The stream channel shall be excavated no deeper than the natural bed material of the stream, to the
maximum extent practicable. Efforts must be made to minimize impacts to the stream banks, as well as to
vegetation responsible for maintaining the stream bank stability.
General Conditions:
9. 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.
10. 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.
11. 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.
12. 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.
13. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
14. 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. No temporary impacts have been approved for dewatering. If temporary impacts are
necessary, a modification to this permit will be required.
15. 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.
16. This approval will expire with the accompanying 404 federal permit.
17. 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.
18. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
19. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
20. 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 NCD WQ 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.
21. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by 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.
25. 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.
26. Native riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
27. 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.
28. 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: -
29. 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.
a. 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.
b. 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.
c. The reclamation measures and implementation must comply with the reclamation in accordance
with the requirements of the Sedimentation Pollution Control Act.
d. 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
expiation 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 150B 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.
