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 modification application dated
received December 5, 2008 and additional information received electronically January 8, 15, and 16,
2005. Should your project change, you are required to 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 any additional wetland 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 Storm Water, 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.
Conditions of Certification:
The natural rock energy dissipator proposed at Permit Site #16 (Permit Drawing Sheet 14 of 31) shall
be constructed per Detail Sheet 2 -K. Rock used to construct the dissipator and associated "rock sill"
shall be constructed so that low flow passage of water or aquatic life is impeded.
2. A natural rock energy dissipator (Detail Sheet 2 -K) is proposed on the stream bank, in a level area for
constructability (per NCDOT staff) at Permit Site #2 (Permit Drawing Sheet 16 of 31, - YRPC -). The
dissipator is designed such that storm flows will be directed upstream once they exit the dissipator.
NCDOT is advised that if the stream destabilizes in this area due to backwater or other conditions
caused by the dissipator alignment, corrective actions to stabilize the stream will be required.
3. Two (2) ditch lines are proposed on the stream banks at Permit Site #2 (Permit Drawing 16 of 31, -
YRPC -) which discharge into the stream at nearly right angles. NCDOT is advised that if stream bank
destabilization occurs as a result of the ditch line alignments, corrective actions to stabilize the stream
will be required.
4. The stream is relocated to a ditch line at Permit Site #13 (Permit Drawing 24 of 31) and then conveyed
into the natural stream. The ditch line appears to discharge to the natural stream at nearly a right
angle. NCDOT is advised that if stream bank destabilization occurs as a result of the ditch line
alignment, corrective actions to stabilize the stream will be required.

Three (3) overflow culverts will be installed at Permit Site #5 (Permit Drawing 26 of 31). An "overflow
channel" is depicted on the outlet end of the overflow culverts. Per NCDOT staff, no excavation or
other earthwork will be required to tie the "overflow channel" into the existing stream. If excavation or
other earthwork is required, on the streambanks or in the stream, to provide a connection from the
overflow channel to the stream, a detail shall be provided to ensure that no additional jurisdictional
impacts will be incurred and the stream will remain stable.
6. Class B riprap is proposed for the channel relocation at Permit Site 14 (Permit Drawing 28 of 31) and
the outfall from the associated ditch line. 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. In addition, riprap shall be of sufficient size
such that it is not carried downstream by normal stream flow.
7. At locations where ponds will be drained, proper measures will be taken to drain the pond with limited
impact to upstream and downstream channel stability as well as to native aquatic species. Proper
measures will be taken to avoid sediment release and/or sediment accumulation downstream as a
result of pond draining. If typical pond draining techniques will create significant disturbance to native
aquatic species, additional measures such as collection and relocation may be necessary to prevent a
significant fish kill. NCDOT shall consult with the NC Wildlife Resources Commission Staff to
determine if there are any sensitive species, and the most appropriate measures to limit impacts to
these species.
8. A sill shall be placed on one of the box culverts to maintain the natural stream dimension at Permit
Sites 2 (Permit Drawing 16 of 31) and 7 (Permit Drawing 30 of 31).
9. Placement of culverts and other structures in waters, streams and wetlands shall be below the
elevation of the streambed by one (1) foot for all culverts with a diameter greater than 48 inches and 20
percent of the culvert diameter for culverts having a diameter of less than 48 inches, to allow for 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
disequilibrium of wetlands or streambeds or banks, adjacent to or upstream and downstream of the
above structures. The applicant is required to .provide evidence that the equilibrium is being maintained
if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting
features encountered during construction, please contact the NCDWQ for guidance on how to proceed
and to determine whether or not a modification to this certification will be required.
10. Compensatory mitigation for 4,234 linear feet of streams and 3.97 acres of impacts to riverine wetlands
is required. We understand that you have chosen to perform compensatory mitigation for impacts to
wetlands 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 October 22,
2008, 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.
11. Due to the possibility that compaction and/or other site alterations might prevent the temporary wetland
impact areas from re- attaining jurisdictional wetland status, the permittee shall schedule an agency field
meeting with the NC Division of Water Quality to determine if the wetland areas temporarily impacted
by this project have re- attained jurisdictional wetland status. If the temporarily impacted wetland areas
have not re- attained jurisdictional wetland status, NC Division of Water Quality shall determine if
compensatory wetland mitigation will be required.
12. 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.

13. During construction of the project, no staging of equipment, of any kind, is permitted in waters of the
U.S. or protected riparian buffers.
14. The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings
submitted for approval.
15. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact
between curing concrete and surface waters. 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.
16. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams should be restored to natural geomorphic conditions.
17. 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 the 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.
18. 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.
19. 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.
20. No rock, sand or other materials shall be dredged from the stream channel except where authorized by
this Certification.
21. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited.
22. Native riparian vegetation must be re- established within the construction limits of the project by the end
of the growing season following completion of construction.
23. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated
this permit without appropriate modification. Should 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.
24. 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 water 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.

25. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise
approved by this Certification.
26. 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 governmental 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.
27. The Permittee shall report any violations of this certification to the Division of Water Quality within 24
hours of discovery.
28. A copy of this Water Quality Certification shall be posted 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.
29. Upon completion of the project, 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.
30. 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), that State or Federal law is being violated, or that further conditions are necessary to
assure compliance, DWQ may re- evaluate and modify 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 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.
