Approval of 401 Water Quality Certification with Additional Conditions
Dear Mr. Vena:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.03 acres of wetlands by fill; 6.03 acres of wetlands by permanent
conversion; and 4.10 acres of wetlands by temporary impacts. This approval also authorized 880 feet of
temporary stream impacts for replacement of existing 4 -inch gas line with new 6 -inch gas line on
existing and new right -of -way, as described within your application dated September 9, 2013 and
received by the N.C. Division of Water Resources (DWR) on September 12, 2013. After reviewing your
application, the proposed impacts are covered by General Water Quality Certification Number(s) 3884
(GC3884). The Certification(s) allows you to use Nationwide Permit(s) 12 when issued by the US Army
Corps of Engineers (USACE). 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, Non - discharge, and Tar River Riparian Buffer rules. 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
The following impacts are hereby approved as long as all of the other specific and general conditions
of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved
including incidental impacts:
2. Erosion & Sediment Control Practices
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 and the Mining
Act of 1971.
e. If the project occurs in waters or watersheds classified as Primary Nursery Areas (PNAs),
Trout Jr), SA, WS -I, WS -11, High Quality (HQW), or Outstanding Resource (ORW) waters,
then the sediment and erosion control requirements contained within Design Standards in
Sensitive Watersheds (15A NCAC 04B .0124) supersede all other sediment and erosion
control requirements.
3. 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 and authorized by this written
approval, including incidental impacts. 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.

4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters without prior approval
by DWR. If placement of sediment and erosion control devices in wetlands and waters is unavoidable,
then 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
downstream of the above structures. All devices shall be removed and the natural grade restored within
two (2) months of the date that the Division Energy, Mining and of Land Resources has released the
project.
5. If concrete is used during the construction, then a dry work area should be maintained to prevent
direct contact prevent direct contact between curing concrete and stream water. Water that
inadvertently contacts uncured concrete should not be discharged to surface waters due to the
potential for elevated pH and possible aquatic life /fish kills.
6. Work in the Dry
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved best
management practices from the most current version of the NC Sediment and Erosion Control
Manual, or the NC DOT Construction and Maintenance Activities Manual, such as sandbags,. rock
berms, cofferdams, and other diversion structures shall be used to minimize excavation in flowing
water.
7. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification or applicable
Buffer Rules, and any subsequent modifications, the applicant is required to return the attached
certificate of completion to the 401 Oversight/Express Review Permitting Unit, North Carolina
Division of Water Resources, 1650 Mail Service Center, Raleigh, NC, 27699 -1650.
8. Diffuse Flow
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 .0259(5)
9. The applicant/permittee and their authorized agents shall conduct all 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 the Division determines that such standards or laws are not being met, including 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, then the Division may reevaluate and modify this General Water
Quality Certification.
Violations of any condition herein set forth may result in revocation of this Certification and may result in
criminal and /or civil penalties. The authorization to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application and as authorized by this Certification shall expire upon
expiration of the 404 Permit.
