1 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 (► a local state and federal)
having jurisdiction including but not limited to applicable buffer rules stormwater management rules soil
erosion and sedimentation control requirements etc
2 The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of
discovery
3 The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings
submitted for approval
4 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) or that State or federal law
is being violated or that further conditions are necessary to assure compliance DWQ may reevaluate and
modify this certification
5 All portions of the proposed project draining to 303(d) listed watersheds that are impaired due to biological
criteria exceedances shall not discharge stormwater directly to surface waters Stormwater shall be treated
using appropriate best management practices (e g vegetated conveyances constructed wetlands detention
ponds etc ) prior to discharging to surface waters
6 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
7 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
8 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
9 During the construction of the protect no staging of equipment of any kind is permitted in waters of the U S or
protected riparian buffers
10 The dimension pattern and profile of the stream above and below the crossing shall not be modified
Disturbed floodplams and streams shall be restored to natural geomorphic conditions
11 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

Page 3 of 5
12 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
13 No rock sand or other materials shall be dredged from the stream channel except where authorized by this
certification

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

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
19 New roadside ditches must be in compliance with the nitrogen control and diffuse flow requirements outlined in
15A NCAC 2B 0259
20 Native riparian vegetation (ex list 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
21 There shall be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this
certification 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
