Should your project change you must notify the DWQ 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) For this approval to remain valid you must adhere to the
conditions listed in the attached certif► ►cation

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
3 The Perm►ttee shall ensure that the final design drawings adhere to the certifi ►cation and to the drawings
submitted for approval

or vibration techniques) prescribed by the NC Wildlife Resources Commission and NC Division of Marine
Fisheries No in water work is permitted between February 15 and June 15 of any year without prior approval
from the NC Division of Water Quality and the NC Wildlife Resources Commission In addition the permittee
shall conform with the NCDOT policy entitled Stream Crossing Guidelines for Anadromous Fish Passage
(May 12 1997) at all times
5 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
6 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
7 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
8 The dimension pattern and profile of the stream above and below the crossing shall not be modified
Disturbed floodpla►ns and streams shall be restored to natural geomorphic conditions
9 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
10 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
11 No rock sand or other materials shall be dredged from the stream channel except where authorized by this
certification
12 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited

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 The outside buffer wetland or water boundary located within the construction corridor approved by this
certification 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
15 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
16 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
17 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
18 Strict adherence to the most recent version of NCDOT s Best Management Practices For Bridge Demolition
and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality
Certification
19 The post construction removal of any temporary bridge structures must return the project site to its
