5. 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 for this
project. 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.
Approved plans and specifications for this project are incorporated by reference and are
enforceable parts of this permit. [15A NCAC 02H .0501 and .0502]
6. 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. If applicable, the project must comply with the specific conditions
and requirements of the NPDES Construction Stormwater Permit issued to the site and the
following requirements [15A NCAC 02H .0506(b)(3) and (c)(3)]:
a. 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.
b. 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.
c. 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.
d. Sufficient materials required for stabilization and/or repair of erosion control
measures and stormwater routing and treatment shall be on site at all times.
6. Sediment and erosion control measures shall not be placed in wetlands or waters.
Exceptions to this condition require application submittal to and written approval by the
Division. 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, stream beds, or
banks, adjacent to or upstream and downstream 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 Energy, Mineral and Land Resources (DEMLR) or
locally delegated program has released the specific area within the project. [15A NCAC 02H
.0501 and .0502]

7. An NPDES Construction Stormwater Permit is required for construction projects that disturb
one (1) or more acres of land. This Permit allows stormwater to be discharged during land
disturbing construction activities as stipulated in the conditions of the permit. If your
project is covered by this permit, full compliance with permit conditions including the
erosion & sedimentation control plan, inspections and maintenance, self-monitoring, record
keeping and reporting requirements is required. A copy of the general permit
(NCG010000), inspection log sheets, and other information may be found at:
http://Portal.ncdenr.org/web/wq/ws/su/npdessw#tab-w. 15A NCAC 02H .0506(b)(5) and
(c)(5)]
8. All work in or adjacent to stream waters shall be conducted so that the flowing stream does
not come in contact with the disturbed 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. [15A
NCAC 02H .0506(b)(3) and (c)(3)]
9. If concrete is used during the construction, then all necessary measures shall be taken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state
due to the potential for elevated pH and possible aquatic life/fish kills. [15A NCAC 02B .02001
10. Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered and to allow for aquatic life movement during low flows. Existing
stream dimensions (including the cross section dimensions, pattern and longitudinal profile)
must be maintained above and below locations of each culvert. [15A NCAC 02H .0506(b)(2)
and (c)(2)]
Placement of culverts and other structures in waters, streams must be below the elevation
of the streambed by one (1) foot for all culverts with a diameter greater than 48 inches, and
20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to
allow low flow passage of water and aquatic life.
Installation of culverts in wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. Additionally, when
roadways, causeways, or other fill projects are constructed across FEMA -designated
floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the floodway that
may result in destabilization of streams or wetlands.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable instead of rip rap or other bank hardening
methods.

11. All temporary fill and culverts shall be removed and the impacted area returned to natural
conditions, within 60 days of the determination that the temporary impact is no longer
necessary. The impacted areas shall be restored to original grade, including each stream's
original cross sectional dimensions, plan form pattern, and longitudinal bed and bed profile,
and the various sites shall be stabilized with natural woody vegetation (except approved
maintenance areas) and restored to prevent erosion. [15A NCAC 02H .0506(b)(2) and (c)(2)]
12. All temporary pipes/culverts/riprap pads etc, shall be installed in all streams as outlined in the
most recent edition of the North Carolina Sediment and Erosion Control Planning and Design
Manual so as not to restrict stream flow or cause dis-equilibrium. [15A NCAC 02H .0506(b)(2)
and (c)(2)]
13. Any riprap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All riprap shall be buried and/or "keyed in" such that the original
stream elevation and streambank contours are restored and maintained. Placement of riprap
or other approved materials shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area. [15A NCAC 02H .0506(b)(2)]
14. Any riprap used for stream stabilization shall be of a size and density to prevent movement by
wave action, current action, or stream flows and consist of clean rock or masonry material
free of debris or toxic pollutants. Riprap shall not be installed in the streambed except in
specific areas required for velocity control and to ensure integrity of bank stabilization
measures. [15A NCAC 02H .0506(b)(2)]
15. A one-time application of fertilizer to re-establish vegetation is allowed in disturbed areas
including riparian buffers, but is restricted to no closer than 10 feet from top of bank of
streams. Any fertilizer application must comply with all other Federal, State and Local
regulations. [15A NCAC 02B.0267(6) and 15A NCAC 02B.0231)
16. This Certification does not relieve the applicant of the responsibility to obtain all other
required Federal, State, or Local approvals.
17. Mr. Alex Rosser and Piedmont Triad Airport Authority shall conduct construction activities in a
manner consistent with State water quality standards (including any requirements resulting
from compliance with section 303(d) of the Clean Water Act) and any other appropriate
requirements of State and Federal law. [15A NCAC 02B .02001 If the Division 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, the Division may reevaluate and modify this Certification.
Before modifying the Certification, the Division shall notify Mr. Alex Rosser and Piedmont
Triad Airport Authority and the U.S. Army Corps of Engineers, provide public notice in
accordance with 15A NCAC 02H .0503 and provide opportunity for public hearing in
accordance with 15A NCAC 02H .0504. Any new or revised conditions shall be provided to
Mr. Alex Rosser and Piedmont Triad Airport Authority in writing, shall be provided to the U.S.

Army Corps of Engineers for reference in any Permit issued pursuant to Section 404 of the
Clean Water Act, and shall also become conditions of the 404 Permit for the project.
18. This approval is for the purpose and design described in your application and as described in
the Public Notice. The plans and specifications for this project are incorporated by reference
and are an enforceable part of the Certification. If you change your project, you must notify
the Division and you may be required to submit a new application package with the
appropriate fee. If the property is sold, the new owner must be given a copy of this
Certification and is responsible for complying with all conditions. Any new owner must notify
the Division and request the Certification be issued in their name. [15A NCAC 02H .0501 and
.0502]
19. The applicant and/or authorized agent shall provide a completed Certificate of Completion
Form to the DWR 401 & Buffer Permitting Branch within ten days of project completion
(available at: http://portal.ncdenr.org/web/wq/swp/ws/401/certsandpermits/apply/forms).
[15A NCAC 02H .0502(f)]
20. This certification grants permission to the director, an authorized representative of the
Director, or DENR staff, upon the presentation of proper credentials, to enter the property
during normal business hours. [15A NCAC 02H .0502(e)]
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 or CAMA Permit. The
conditions in effect on the date of issuance shall remain in effect for the life of the project,
regardless of the expiration date of this Certification. [15A NCAC 02H .0507(d)(2) and 15A NCAC
