along streambanks or within wetlands. [15A NCAC 02B .0201]
12. An NPDES Construction Stormwater Permit (NCG010000) is required for construction projects
that disturb one (1) or more acres of land. The NCG010000 Permit allows stormwater to be
discharged during land disturbing construction activities as stipulated in the conditions of the
permit. If the project is covered by this permit, full compliance with permit conditions

diversion structures shall be used to minimize excavation in flowing water. [15A NCAC 02H
.0506(b)(3) and (c)(3)]
14. Application of fertilizer to establish planted/seeded vegetation within disturbed riparian areas
and/or wetlands shall be conducted at agronomic rates and shall comply with all other Federal,

shall be restored to original grade, including each stream's original cross sectional dimensions,
planform pattern, and longitudinal bed profile. All temporarily impacted sites shall be restored
and stabilized with native vegetation. [15A NCAC 02H .0506(b)(2) and (c)(2)]

Maintenance Activities so as not to restrict stream flow or cause dis-equilibrium during use of
this Certification. [15A NCAC 02H .0506(b)(2) and (c)(2)]
18. 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)]
19. Any rip -rap used for stream or shoreline stabilization shall be of a size and density to prevent
movement by wave, current action, or stream flows and shall consist of clean rock or masonry
material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed
except in specific areas required for velocity control and to ensure structural integrity of bank
stabilization measures. [15A NCAC 02H .0506(b)(2)]
20. This Certification does not relieve the applicant of the responsibility to obtain all other required
Federal, State, or Local approvals before proceeding with the project, including those required
by, but not limited to Sediment and Erosion Control, Non -Discharge, Water Supply Watershed,
and Trout Buffer regulations.
21. All mechanized equipment operated near surface waters shall be inspected and maintained
regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids, or
other toxic materials. Construction shall be staged in order to minimize the exposure of
equipment to surface waters to the maximum extent practicable. Fueling, lubrication and
general equipment maintenance shall not take place within 50 feet of a waterbody or wetlands
to prevent contamination by fuels and oils. [15A NCAC 02H .0506(b)(3) and (c)(3) and 15A NCAC
02B .0211 (12)]
22. Heavy equipment working in wetlands shall be placed on mats or other measures shall be taken
to minimize soil disturbance. [15A NCAC 02H .0506(b)(3) and (c)(3)]

24. Mr. J. 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 .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

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.
25. Upon completion of all permitted impacts included within the approval and any subsequent
modifications, the applicant shall be required to return a certificate of completion (available on
the DWR website https://edocs.deg.nc.gov/Forms/Certificate-of-Completion). [15A NCAC 02H

Certification (and written authorization if applicable) and is responsible for complying with all
conditions. [15A NCAC 02H .0501 and .0502]
27. This Certification neither grants nor affirms any property right, license, or privilege in any
waters, or any right of use in any waters. This Certification does not authorize any person to
interfere with the riparian rights, littoral rights, or water use rights of any other person and this
Certification does not create any prescriptive right or any right of priority regarding any usage
of water. This Certification shall not be interposed as a defense in any action respecting the
determination of riparian or littoral rights or other rights to water use. No consumptive user is
deemed by virtue of this Certification to possess any prescriptive or other right of priority with
respect to any other consumptive user regardless of the quantity of the withdrawal or the date
on which the withdrawal was initiated or expanded.
28. 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)]
