Condition(s) of Certification:
Project Specific Conditions
1. For the 40 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. [15A NCAC 02H.0506(b)(2)]
2. 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 iiue to the
potential for elevated pH and possible aquatic life and fish kills. [15A NCAC 02B.0200]
3. 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. Any applicable riparian buffer impact for
access to stream channel shall be temporary and be revegetated with native riparian species. [15A NCAC
02H.0506(b)(2)]
4. This project has the potential to impact trout waters or other aquatic species of concern. No construction
activities shall begin until the NCWRC makes a determination regarding moratoria. Should the NCWRC
determine that a moratorium is applicable then the requirements of any moratorium(s) shall be a condition
of this 401 Certification. [15A NCAC 02H .0506(b)(2) and 15A NCAC 04B.0125]
5. Stormwater shall be directed to vegetated buffer areas, grass-lined ditches or other means appropriate to
the site for pre-treating storm water runoff prior to discharging directly into streams. Mowing of existing
vegetated buffers is strongly discouraged. [15A NCAC 02B.0224 and 0225]
6. The permittee shall use Design Standards in Sensitive Watersheds (15A NCAC 4B.0124[a]-[e]) in areas
draining to Trout waters. NCDOT shall be in compliance with the NCS000250 issued to the NCDOT,
including the applicable requirements of the NCGO 10000.
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 NCDWR. If this condition is unable to be met due to bedrock or other limiting
features encountered during construction, please contact NCDWR for guidance on how to proceed and to
determine whether or not a permit modification will be required. [15A NCAC 02H.0506(b)(2)]
2. 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. [15A NCAC 02H.0506(b)(2)]
3. 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. [15A NCAC
02H.0506(b)(2)]
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 it does not impede aquatic life
passage. [15A NCAC 02H.0506(b)(2)]
5. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
6. 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. [ISA NCAC 02H.0506(b)(3) and (c)(3)]
7. 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. [15A NCAC
02H.0506(b)(3)]
8. 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. [15A
NCAC 02H.0506(b)(3)] �
9. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification. [15A NCAC 02H.0506(b)(3)]
10. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited. [15A NCAC 02H.0506(b)(3)]
11. 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. [15A NCAC 02B.0200] '
12. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification. [15A NCAC 02H.0506(b)(2)]
13. 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. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and
��)�2)� '
14. 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. [15A NCAC
02H.0501 and .0502] '
15. 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.
16. The Permittee shall report any violations of this certification to the Division of Water Resources within 24
hours of discovery. [15A NCAC 02B.0506(b)(2)] "

project by the end of the growing season following completion of construction. [15A NCAC 02B.506(b)(2)]
19. 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. [15A NCAC 02H.0506(b)(3) and (c)(3)]
20. Erosion and sediment conhol practices must be in full compliance with all specifications goveming the proper
design, installation and operation and maintenance of such Best Management Practices in order to protect
