Dear Sir:
You have our approval, in accordance with the attached conditions and those listed below, to fill or otherwise
impact 0.06 acre of 404 wetlands (permanent impacts) for commercial development, as described in your
application dated June 27, 2012 and received by the Division of Water Quality (DWQ) on June 28, 2012 and
additional information received August 24, 2012. After reviewing your application and additional information,
we have decided that the impacts are covered by General Water Quality Certification Number(s) 3890 (GC3890).
The Certification(s) allows you to use Nationwide Permit(s) NW39 when issued by the US Army Corps of
Engineers (USACE). 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, Non -
discharge regulations, and Jordan buffer impacts. 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
below.
The Additional Conditions of the Certification are:
1. Impacts Approved

footprint of the impacts depicted in the Pre - Construction Notification. All construction activities,

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

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;
