Jordan Lake Riparian Buffer Impacts (Allowable)
Total Buffer Impact for Project: 3,625 square feet.
The project shall be constructed in accordance with your application dated received March 20, 2014. After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Number 3886. 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 NCDWR 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 02B .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
I . For the 24 linear feet of streams being impacted due to site dewatering activities, the site shall be graded to
its preconstruction contours and revegetated with appropriate native species.
General Conditions
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 downstream of the above
structures. The applicant is required to provide evidence that the equilibrium is being maintained if requested
in writing by the NCDWR. If this condition is unable to be met due to bedrock or other limiting features
encountered during construction, please contact the NCDWR for guidance on how to proceed and to
determine whether or not a permit modification will be required.
2. 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.
3. 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.

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.
3. 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.
4. 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.
5. 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.
6. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
7. 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.
8. 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.
9. 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.
10. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.
i
12. 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 the NCDWR 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, the NCDWR
may reevaluate and modify this certification.
13. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification..
14. 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.
15. 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.
16. 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.
17. The Permittee shall report any violations of this certification to the Division of Water Resources within 24
hours of discovery.
18. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDOT
Division Engineer, applicant or agent of, shall complete and return the enclosed "Certification of Completion
Form" to notify the NCDWR when all work included in the 401 Certification has been completed.
19. Native riparian vegetation must be reestablished in the riparian areas within the construction limits of the
project by the end of the growing season following completion of construction.
1
20. 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.
21. 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.
22. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved
by this Certification.
23. All stormwater runoff shall be directed as sheetflow through stream buffers at non - erosive velocities, unless
otherwise approved by this certification.
24. 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 Oermanently 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.
25. Pursuant to 15A NCAC 213 .0267, sediment and erosion control devices shall not be placed in Zone 1 of any
Buffer without prior approval by the NCDWR. At this time, the NCDWR 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.
26. Any modifications to this 401 Water Quality Certification that propose additional stream impacts or increased
impervious surface requiring additional stormwater management may be subject the Jordan Water Supply
Nutrient Strategy (15A NCACO2B .0267). The NCDOT shall coordinate with the NCDWR prior to
submitting a modification request to determine the applicability of the Jordan Water Supply Nutrient
Strategy. This condition does not apply to major modifications for additional sections of the project that were
covered under the Finding of No Significant Impact or approved in the Avoidance and Minimization stage of
the project.
