The project shall be constructed in accordance with your application dated received April 29, 2010. 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 Neuse Riparian Buffer Rules (15A NCAC 213.0233). 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 NCDW Q 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 0213.0242. For this approval to remain valid, you must adhere to the conditions listed in
the attached certification and any additional conditions listed below.
Conditions of Certification:
1. Compensatory mitigation for impacts to 21 square feet of protected riparian buffers in Zone 1 and 1360 square feet
of protected riparian buffers in Zone 2 shall be required. In accordance with 15A NCAC 02B.0242(9), riparian
vegetation reestablishment shall include a minimum of at least 2 native hardwood tree species planted at a density -
sufficient to provide 320 trees per acre at maturity. All on-site mitigation sites shall be protected in perpetuity by a
conservation easement or through NCDOT fee simple acquisition and recorded in the NCDOT Natural Environment
Unit mitigation geodatabase. . . _ .
2. The perrnittee shall monitor the buffer mitigation site. Monitoring shall consist of visual review with photo points
for channel stability and vegetation survival. An annual report shall be submitted to NCDWQ for a period.of:3 years
showing monitoring results, survival rate/ success of tree and vegetation establishment, and that diffuse flow through
the riparian buffer has been maintained. The first annual report shall be submitted within one year of final planting.
Failure to achieve a buffer density of 320 trees per acre after 3 years will require the annual report to provide
appropriate remedial actions to be implemented and a schedule for implementation. Approval of the final annual
report, and a formal "close out" of the mitigation site by NCDWQ is required. ...
3. 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.
4. 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.
5. For any streams being impacted due to site dewatering activities, the site shall be graded to its preconstruction
contours and revegetated with appropriate native species.
6. All storinwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
7. 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.
8. Pursuant to NCAC 15A 2B.0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by NCDWQ. At this time, 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 I is not compromised and that
discharge is released as diffuse flow.
9. 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.
10. 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.
11. 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.
12. 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.
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.
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. 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.
17. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.:
18. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited:
19. 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 (includinn the failure to sustain a designated or achieved use) or that State or federal law is heing violated, or that
further conditions are necessary to assure compliance, NCDWQ may reevaluate and modify this certification.
20. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise ..
authorized by this certification..
21. 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.
22. 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.
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 Pemuttee 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 (i.e., trees and shrubs native to your geographic region) 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:
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.
29. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by
this Certification.
If you do not accept any of the conditions of this. certification; you may ask for an adjudicatory _hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms to
Chapter 150B of the North Carolina. General Statutes to the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, N.C. 27699. This certification and its conditions are final and binding unless you ask for a heating.
This letter completes the review of the Division of Water Quality under. Section 401 of the Clean Water Act. If you
have any questions, please contact Rob Ridings at 919-733-9817.
