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]
9. Erosion and sediment control practices must be in full compliance with all specifications

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.
10. 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]
11. 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:

12. 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)]
13. 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 .0200]
14. This Certification does not relieve the applicant of the responsibility to obtain all other
required Federal, State, or Local approvals.
15. Mr. J. Alex Rosser and Piedmont Triad Airport Authority shall conduct construction activities

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 .0200] 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. J. 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. J. Alex Rosser and Piedmont Triad Airport Authority in writing, shall be provided to the

the Clean Water Act, and shall also become conditions of the 404 Permit for the project.
16. 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)]
17. 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
02H.05061

Non-compliance with or violation of the conditions herein set forth may result in revocation of
