Condition(s) of Certi�cation:
Project Specific Conditions
1. As a condition of this Riparian Buffer Authorization, the bridge demolition and construction must be
accomplished in strict compliance with the most recent version of NCDOT's Best Management Practices
for Construction and Maintenance Activities. [15A NCAC 02H .0507(d)(2) and 15A NCAC 02H
- .0506(b)(5)]
2. The post-construction removal of any temporary bridge structures must return the project site to its
preconstruction contours and elevations. The impacted areas shall be revegetated with appropriate native
species. [15A NCAC 02H .0506(b)(2)] _
3. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed across the
bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated
buffers, etc.) before entering the stream. To meet the requirements of NCDOT's NPDES permit
NCS000250 please refer to the most recent version of the North Carolina Department of Transportation
Stormwater Best Management Practices Toolbox manual for approved measures. [15A NCAC 02H
.0507(d)(2) and 15A NCAC 02H .0506(b)(5)]
4. All stormwater runoff shall be directed as sheetflow through stream buffers at non-erosive velocities, unless
otherwise approved by this certification. [15A NCAC 2B.0267]
5. 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. [15A NCAC 2B.0267]
6. Pursuant to 15A NCAC 2B .0267, sediment and erosion control devices shall not be placed in Zone 1 of any
Jordan Lake 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.
7. Any modifications to this Riparian Buffer Authorization which may propose 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.
General Conditions
1. 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. 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.
[15A NCAC 02B.0200]
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. [15A NCAC 02H.0506(b)(2)]
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. [15A NCAC
02H.0506(b)(2)]
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.
[15A NCAC 02H.0506(b)(2)]
6. 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)]
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 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. [15A NCAC 02H.0506(b)(3) and (c)(3)]
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. [15A NCAC 02H.0506(b)(3)] ,
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. [15A
NCAC 02H.0506(b)(3)]
10. 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)]
11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited. [15A NCAC 02H.0506(b)(3)]
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. [15A NCAC 02B.0200]
13. All fll 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)]
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. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506
(b)(2) and (c)(2)]
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 activ,ities. Impacts
to areas within the fencing are prohibited unless otherwise authorized by this certification. [15A NCAC
02H.0501 and .0502]
16. The issuance of this certifcation 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 cerkification to the Division of Water Resources within 24
hours of discovery. [15A NCAC 02B.0506(b)(2)]

Division Engineer (or appointee) 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. [15A NCAC
02H.0502(�]
19. Native riparian vegeta[ion must be reestablished in the riparian areas wi[hin the cons[ruction limits of the
project by the end of the growing season following completion of cons[ruction. [I SA NCAC 02B.0267(10)]
20. There shall be no excavation from, or was[e disposal into, jurisdictional wetlands or wa[ers associa[ed with
this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow
sites, be located in wedands or streams, compensatory mitigation will be required since that is a direct impact
from road construction activities. [ISA NCAC 02H.0506(b)(3) and (c)(3)]
21. Erosion and sedimen[ control practices mus[ be in full compliance with all specifications governing the proper
design, installation and operation and maintenance of soch Best Management Practices in order to protect
