The project shall be constructed in accordance with your application dated received September 18, 2008 After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Numbers 3701 and 3689 This certification corresponds to the Nationwide Permits 23 and 13 issued by the Corps of
Engineers This approval is also valid for the Neuse Riparian Buffer Rules (15A NCAC 2B 0233) 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 DWQ and submit anew 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 certification as well as those listed below
Conditions of Certification*
1 Compensatory mitigation for impacts to 1891 square feet of protected riparian buffers in Zone 1 at a 3 1 ratio and
3667 square feet of protected riparian buffers in Zone 2 at a 1 5 1 ratio shall be required We understand that you
have chosen to perform compensatory mitigation for impacts to protected buffers through use of the North Carolina
Ecosystem Enhancement Program (EEP) Mitigation for unavoidable impacts to Neuse Riparian Buffers shall be
provided in the Neuse River Basin and done in accordance with 15A NCAC 2B 0233 EEP has indicated in a letter
dated September 4, 2008 that they will assume responsibility for satisfying the compensatory mitigation
requirements for the above-referenced project, in accordance with the Tri-Party MOA signed on July 22, 2003 and
the Dual-Party MOA signed on April 12, 2004
2 Due to the possibility that compaction and/or other site alterations might prevent the temporary wetland impact
area from re-attaining Junsdictional wetland status, the permittee shall provide an update on the wetland areas at
these temporary impact sites no later than three years after protect completion This update will consist of
photographs and a brief report on the status of these temporarily impacted areas in re-attaining wetland jurisdictional
status If at the end of three years the wetland areas temporarily impacted by this project have not re-attained
jurisdictional wetland status, NC DWQ shall determine if compensatory wetland mitigation will be required
3 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
4 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
5 Bridge deck drams shall not discharge directly into the stream Stormwater shall be directed across the budge
and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated buffers, etc )
before entering the stream Please refer to the most current version of Stormwater Best Management Practices

6 If multiple pipes or barrels are required, they shall be designed to tmmnc natural stream cross section as closely as
possible including pipes or barrels at flood plain elevation and/or sills where appropriate Widening the stream
channel should be avoided Stream channel widening at the mlet or outlet end of structures typically decreases
water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage
7 Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes
aquatic life passage Bioengineering boulders or structures should be properly designed, sized and installed
8 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification
9 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 DOT
maintenance activities including mowing The area with non-mamtained buffers shall be permanently revegetated,
with native woody species before the next growing season following completion of construction
10 Pursuant to NCAC15A 2B 0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by the NCDWQ At this time, the NCDWQ 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
compronused and that discharge is released as diffuse flow
11 If concrete is used during construction, a dry work area shall be maintained to prevent direct contact between
curmg 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
12 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
13 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
14 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
15 The Permnttee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval
16 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
17 Heavy equipment shall be operated from the banks rather than in the stream channel in order to mimmuze
sedimentation and reduce the introduction of other pollutants into the stream
18 All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent
contamnnation of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials

certification
20 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited
21 The perm ittee 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
22 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1, unless otherwise
authorized by this certification
23 A copy of this Water Quality Certification shall be maintained on site at 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
24 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
25 The issuance of this certification does not exempt the Pernuttee from complying with any and all statutes, rules,
regulations, or ordinances that may be imposed by other government agencies (i 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
26 The Pernuttee shall report any violations of this certification to the Division of Water Quality within 24 hours of
discovery
27 Upon completion of the project (including any impacts at associated borrow or waste site), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify DWQ when
all work included in the 401 Certification has been completed
28 Native riparian vegetation (i e , 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
29 There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this
pernut 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
30 Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by
this Certification
