Authority, who have authorization to place fill within or otherwise impact 0.9 acres of
404 /wetland and 1,796 linear feet of stream, as described within your application received by the
N.C. Division of Water Quality (Division) on June 14, 2011, by Public Notice issued by the USACE
on June 24, 2011 and received by the DWQ on June 24, 2011, and by additional information
received on August 30, 2011, September 15, 2011, January 4, 2013 and February 11, 2013.
The application and supporting documentation provides adequate assurance that the proposed
work will not result in a violation of applicable Water Quality Standards and discharge
guidelines. Therefore, the State of North Carolina certifies that this activity will not violate the
applicable portions of Sections 301, 302, 303, 306, 307 of PL 92 -500 and PL 95 -217 if conducted
in accordance with the application, the supporting documentation, and conditions hereinafter
set forth.
This approval is for the purpose and design that you described in your application and as '
described in the Public Notice. 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. Any new owner must notify the Division and request the Certification be issued in
their name. 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
02H .0506 (h). This approval requires you to follow the conditions listed in the certification
below.
Conditions of Certification:
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:

3. Stormwater Management
Before any permanent impervious surface (i.e., building, roadway, taxiway, tarmac or other
similar surface) is installed as part of any phase of the project described in this certification,
the applicant must meet all of the following:
• The Stormwater Management Plan (SMP) must be approved in writing by the City of
Asheville. A copy of the approval letter and approved SMP must be submitted to the
Division prior to installation of any impervious surface within the project site. If the
project is phased, then the approved SMP for each phase must be submitted to the
Division prior to installation of any impervious surfaces associated with that phase.
• The'approved Stormwater best management practices (BMPs) must be constructed
and operational before any permanent building or other structure is occupied or
becomes operational. If the project is phased, then the approved BMPs for each
future phase must be constructed and operational before any permanent building or
other structure associated with that phase is occupied or becomes operational.
• The approved SMP, phased or otherwise, as well as drainage patterns must be
maintained in perpetuity.
• The SMP may not be modified without prior written authorization from the SMP
approval authority.

4. Sediment and Erosion Control
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 and if applicable, comply with the specific conditions and
requirements of the NPDES Construction Stormwater Permit issued to the site:
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.
S. 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 404 /401Permit Application. 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.
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 Land Resources (DLR) or locally delegated program
has released the specific area within the project.
7. Construction Stormwater Permit NCGO10000
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

Asheville Airport Runway Rehabilitation Parallel
Taxiway and Cargo Hold Expansion (West)
Page 6 of 8
February 22, 2013
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 /wci/ws /su /npdessw#tab -w.
8. Culvert Installation
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved
BMP measures from the most current version of NCDOT Construction and Maintenance
Activities manual
(http: / /www.ncdot.org /doh /operations /BMP manual /download /BMP Manual.pdf)
such as sandbags, rock berms, cofferdams and other diversion structures shall be used to
prevent excavation in flowing water.
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section dimensions,
pattern, and longitudinal profile) must be maintained above and below locations of each
culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as
to prevent head cutting of the streams. If any of the existing pipes are or become perched,
the appropriate stream grade shall be re- established or, if the pipes installed in a perched
manner, the pipes shall be removed and re- installed correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the
stream up or down stream of the culvert(s). Existing stream dimensions (including the cross
section dimensions, pattern and longitudinal profile) shall be maintained above and below
locations of each culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed
below the elevation of the streambed by one 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. Design and placement of culverts
and other structures including temporary erosion control measures shall not be conducted in
a manner that may result in dis- equilibrium of wetlands or streambeds or banks, adjacent to
or upstream and down stream of the above structures. The applicant is required to provide
evidence that the equilibrium shall be maintained if requested in writing by DWQ.
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. If rip -rap is necessary, it shall not be placed in the stream bed, unless specifically
approved by the Division of Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions.

9. 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.
10. Continuing Compliance
Mr. Lew Bleiweis and Asheville Regional 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 law and federal law. 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 to include
conditions appropriate to assure compliance with such standards and requirements in
accordance with 15A NCAC 02H .0507(d). Before modifying the Certification, the Division
shall notify Mr. Lew Bleiweis and Asheville Regional 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. Lew Bleiweis and Asheville Regional 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.
11. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained jurisdictional
wetlands, waters and protective buffers in order to assure compliance for future wetland,
water and buffer impact. These mechanisms shall be put in place at the time of recording of
the property, or of individual lots, whichever is appropriate. A sample deed notification can
be downloaded from the Wetlands, Buffers, Stormwater, Compliance and Permitting Unit
web site at: http: / /portal.ncdenr.orpJweb /wq /swp /ws/ 401 /certsandpermits /apply /forms.
