Dear Sir
You have our approval in accordance with the attached conditions and those listed below to fill or otherwise
impact 0 034 acre of 404 wetland (permanent impacts) 0 014 acre of 404 wetland (temporary impacts) 297 linear
feet of perennial stream channel (permanent impacts) 23 linear feet of intermittent stream channel (temporary
impacts) 23 344 square feet of Zone 1 Neuse River basin protected riparian buffer (permanent impacts) and
23 405 square feet of Zone 2 Neuse basin protected riparian buffer (permanent impacts) to construct a residential
subdivision as described in your application received by the Division of Water Quality (DWQ) on December 6
2011 and additional information received by DWQ on January 10 2012 After reviewing your application we
have decided that the impacts are covered by General Water Quality Certification Number(s) 3821 (GC3821)
The Certification(s) allows you to use Nationwide Permit(s) NW29 when issued by the US Army Corps of
Engineers (USACE) This letter shall also act as your approved Authorization Certificate for impacts to the
protected riparian buffers per 15A NCAC 2B 0233 In addition you should obtain or otherwise comply with any
other required federal state or local permits before you go ahead with your project including (but not limited to)
Erosion and Sediment Control and Non discharge regulations Also, this approval to proceed with your
proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon
expiration of the 404 Permit
This approval is for the purpose and design that you described in your application If you change your project
you must notify us and you may be required to send us 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
conditions If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of
stream compensatory mitigation may be required as described in 15A NCAC 2H 0506 (h) This approval
requires you to follow the conditions listed in the attached certification and any additional conditions listed

2 No Waste Spoil Solids or Fill of Any Kind
No waste spoil solids or fill of any kind shall occur in wetlands waters or riparian areas beyond the
footprint of the impacts depicted in the Pre Construction Notification All construction activities
including the design installation operation and maintenance of sediment and erosion control Best
Management Practices shall be performed so that no violations of state water quality standards statutes
or rules occur
3 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 Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times
4 Sediment and Erosion Control Measures
Sediment and erosion control measures shall not be placed in wetlands or waters without prior approval
from the Division If placement of sediment and erosion control devices in wetlands and waters is
unavoidable design and placement of temporary erosion control measures shall not be conducted in a
manner that may result in dis equilibrium of wetlands or stream beds or banks adjacent to or upstream
and down stream of the above structures All sediment and erosion control devices shall be removed and
the natural grade restored within two (2) months of the date that the Division of Land Resources or locally
delegated program has released the project

5 Mitigation (Buffer and Stream)
You are required to mitigate for impacts to the streams and protected riparian buffers
The required mitigation to compensate for 297 linear feet of stream impacts is proposed at 2 1 ratio for a
total of 594 linear feet of stream channel credits of which 297 linear feet of stream channel is required by
DWQ under this 401 Water Quality Certification We understand that you intend to purchase credits
from the Forrest Creek Stream Mitigation Bank in Orange County located in HUC 03020201 to meet this
mitigation requirement The letter (dated December 7 2011) from the Bank Sponsor EBX EM LLC
included in your application packet states that mitigation is currently available for transfer
The required mitigation to compensate for Zone 1 of the protected riparian buffers is 56 517 square feet
and for Zone 2 of the protected riparian buffer is 13 863 square feet as required under this Authorization
Certificate and 15A NCAC 2B 0233 We understand that you intend to purchase credits from the
Wildlife Neuse River Riparian Buffer & Nutrient Umbrella Mitigation Bank — Little River Farm
Mitigation Site located in HUC 03020201 to meet this mitigation requirement The letter (dated January
12 2012) from the Bank Sponsor Wildlands Southeast Holdings I LLC included in your application
packet states that 70 380 square of buffer mitigation credits are available for this project
These contributions of both stream and buffer credit has been determined by the DWQ to be a suitable
method to meet the mitigation requirement Until the EBX EM LLC and Wildland Southeast Holdings I
LLC receive and clear their respective checks and proof of payment has been provided to this Office no
impacts specified in this Authorization Certificate shall occur For accounting purposes, this 401
Water Quality certification and Authorization Certificate authorizes payment into the Forrest
Creek Stream Mitigation Bank and Wildlife Neuse River Riparian Buffer &Nutrient Umbrella
Mitigation Bank — Little River Farm Mitigation Site to meet the following compensatory mitigation
requirements
6 Diffuse flow (DWQ Reviewed Plans)
All stormwater shall be directed as diffuse flow at non erosive velocities through the protected stream
buffers and will not re concentrate before discharging into the stream as identified within 15A NCAC 2B
0233(5) or if this is not possible it is necessary to provide stormwater facilities that are considered to
remove nitrogen
In an effort to comply with the diffuse flow provision of the Buffer Rule (15A NCAC 02B 0233 (5)) you
have provided the DWQ with level spreader designs received by the DWQ on July 16 2008 The DWQ
believes that if implemented as per these plans diffuse flow can be achieved However if diffuse flow
as per 15A NCAC 02B 0233(5) is not achieved then the DWQ shall be notified and corrective actions to
restore diffuse flow shall be taken if necessary to impede the formation of erosion gullies At no time
shall stormwater from the proposed development be piped directly through the buffer without prior DWQ
written authorization
7 Stormwater management plan (No Further Approval Needed)
• The approved SMP must be constructed and operational before any permanent building or other
structure is occupied at the site If a development is phased then the approved SMP for each future
phase must be constructed and operational before any permanent building or other structure associated
with that phase is occupied
• The approved SMP as well as drainage patterns must be maintained in perpetuity
MA
Page 4
• The SMP may not be modified without prior written authorization from the SMP approval authority If
the SMP falls under another state stormwater program then a copy of the approval letter and the
modified SMP must be submitted to the Wetlands Buffers Stormwater Compliance and Permitting
Unit (WeBSCaPe) prior to commencement of the modifications
8 Protective Fencing
The outside buffer wetland or water boundary and along the construction corridor within these
boundaries approved under this authorization shall be clearly marked with orange warning fencing (or
similar high visibility material) for the areas that have been approved to infringe within the buffer
wetland or water prior to any land disturbing activities to ensure compliance with 15 NCAC 2H Section
0500
