Structural Stormwater Best Management Practices (BMPs)
The North Carolina Global TransPark (NCGTP) operates and maintains a total of three (3) structural
stormwater BMPs that collect and treat stormwater runoff from the airport runway, buildings, and parking
areas prior to discharge into surface waters (Table 1). The stormwater runoff that is discharged from the
structural BMP's and other areas within the NCGTP is conveyed to surface waters through a series of
grassed swales and ditches into the Briery Run watershed (south of the runway) or Stonyton Creek
watershed (north and east of the runway) (Figure 1). These streams flow into Jericho Run and then into
the Neuse River approximately seven miles east of the NCGTP. The discharge from a fourth stormwater
BMP, a dry extended detention basin, flows into the City of Kinston wastewater collection system.
Three types of structural BMPs are employed at the NCGTP: 1) oil and water separators; 2) wet detention
basins; and 3) dry extended detention basins. In addition, all fuel tanks are located within concrete
containment structures. This document identifies the location of each stormwater BMP, stormwater
outfalls, receiving waters, and summarizes the current operation and maintenance procedures.
In addition to the stormwater BMP's described below, there are other stormwater BMP's located within
the NCGTP NPDES stormwater permit boundary that are operated and maintained by NCGTP tenants.
For example, three stormwater wetlands have been constructed for the Spirit Aerosystem facility. Fuel
containment structures and oil/water separators are located at other facilities such as the Division of
Forest Resource complex and the Mountain Air Cargo building. NCGTP understands that these BMP's
must be identified and included in the Stormwater Master Plan.
It is the long-term objective of the NCGTP, through a comprehensive stormwater management program,
to protect, maintain, and enhance public health, safety, and general welfare, and to protect the quality of
the environment by establishing minimum requirements and procedures to control the adverse effects of
increased stormwater runoff associated with land development. Detailed operation and maintenance
procedures will be developed and implemented for all structural BMP's as a component of the NCGTP
Stormwater Master Plan.
Oil/Water Separators
An oillwater separator has been installed to treat stormwater runoff from aircraft fueling areas, de-icing
pad, maintenance areas, and buildings associated with the General Aviation Ramp (Figure 2). The
effluent from the runway oil/water separator flows through grassed swales into a roadside ditch and
eventually into a UT of Briery Run (Figure 1, Outfall B). The effluent from the oil/water separators
located inside buildings GTP-2 and GTP-4 discharge into the wastewater.collection system of the City of
Kinston WWTP (Figures 3 and 4).
Wet Detention Basins
A total of two wet detention basins have been installed at the NCGTP to treat stormwater from two
buildings, maintenance areas, and parking lots. At the GTP-2 building, stormwater from the building and
1

►f
}1;
parking lots is conveyed to the basin through pipes (Figure 3). Stormwater runoff from the maintenance
area at the rear of the building flows through a grassed swale prior to entering the basin. The discharge
from this basin flows into a roadside ditch and eventually flows into an unnamed tributary of Stonyton
Creek (Figure 1, Outfall Q.
At the North Cargo building, stormwater from the building and parking lots is conveyed to the wet
detention basin through pipes (Figure 5). The discharge from this basin is conveyed through a series of
ditches into an unnamed tributary of Stonyton Creek (Figure 1, Outfall A).
Dry Extended Detention Basins
One dry extended detention basin is located at GTP-4 on the northeast side of the building (Figure 4).
The primary purpose of this BMP is to provide overflow storage for the wet/dry sumps that are a
component of the fire suppression system for GTP-4. In the event that the automated fire suppression
system is activated, foam and water that exceeds the capacity of the wet/dry sumps flows into the dry
detention basin. In the event that the volume of discharge and/or rainfall exceeds the capacity of the dry
detention basin, the dry detention basin discharges into the oil/water separator and then into the
wastewater collection system of the City of Kinston WWTP.
Oneration and Maintenance
Runoff control measures such as grassed swales, ditches and other outlet channels have been established
throughout the NCGTP property. These features convey stormwater flow to appropriate stormwater BMP
areas and to stormwater outfalls. NCGTP personnel check the condition of the outlet channels on the
property and perform maintenance such as clearing vegetation when necessary. Channels are inspected
annually to identify impediments to stormwater flow.
OiVWater separators and all associated piping, valves, etc. are inspected at least annually for evidence of
free product or debris. In addition oil/water separators are inspected immediately after a spill or other
event that results in the discharge of pollutants being discharged into the oil/water separator. If present,
free product and debris are pumped out by a licensed waste hauler. Debris not contaminated by
petroleum products are removed and disposed of in a licensed landfill.
Wet detention ponds are inspected on an as needed basis but at least annually to ensure that the inlet and
outlets are free of debris and litter. If present, debris and litter not contaminated by petroleum products are
removed and disposed of in a licensed landfill.
Fuel containment structures, including valves and locks, are inspected after each rainfall. If free product
is not present, the stormwater is discharged into an adjacent grassed swale or ditch. If free product is
present, free product and debris are pumped out by a licensed waste hauler.

NCGTP Stormwater Ordinance
On August 5, 2010 the Executive Committee of the NCGTP Board of Directors approved
revisions to the NCGTP Exclusive Development Ordinance, including the addition of the
Stormwater Control and Watercourse Buffer Ordinance (attached). As stated in Section 1, this
ordinance is intended to protect water quality in the Neuse River Basin from additional nitrogen
pollution generated from new development and to preserve existing riparian buffers in that basin.
To achieve these purposes, this section establishes performance standards that: 1) limit the
amount of nitrogen in stormwater runoff; 2) controls stormwater peak runoff rates; 3) promotes
the use of best management practices; and 4) protects existing riparian buffers.

C-1-5 Stormwater Control and Watercourse Buffer Ordinance
Section 1. Title; Purpose.
(a) Title. This chapter shall constitute and be known and may be cited as the "Stormwater
Control and Watercourse Buffer Ordinance" of the North Carolina Global TransPark (NCGTP).
(b) Purpose. This section is intended to protect water quality in the Neuse River Basin from
additional nitrogen pollution generated from new development and to preserve existing
riparian buffers in that basin. To achieve these purposes, this section establishes performance
standards that: limit the amount of nitrogen in stormwater runoff; controls stormwater peak
runoff rates; promotes the use of best management practices; and protects existing riparian
buffers.
Section 2. Definitions.
As used in this chapter, unless the context clearly indicates otherwise, the terms, phrases and
words, and their derivatives, have the meaning given herein:
Best Management Practice or BMP. Stormwater and runoff pollution control devices or
practices designed to reduce the amount of flow or pollutants contained in discharges to the
stormwater conveyance system and receiving waters, which meet standards outlined in the
North Carolina Division of Water Quality Stormwater Best Practices Manual, July 2007.
Buffer. An area of natural or planted vegetation through which stormwater runoff flows in a
diffuse manner so that the runoff does not become channelized and which provides for
infiltration of the runoff and filtering of pollutants. The buffer is measured landward from the
normal pool elevation of impounded structures and from the bank of each side of streams and
rivers.
Environmental Compliance Officer. A person or company retained by NCGTP to review and
implement the NCGTP stormwater master plan. All NCGTP development plans must be
submitted to the Environmental Compliance Officer for review and. approval before
commencing construction.
Ephemeral (Stormwater) Stream. A feature that carries only Stormwater in direct response to
precipitation with waters flowing only during and shortly after large precipitation events. An
ephemeral stream may or may not have a well-defined channel, the aquatic bed is always
above the water table, and Stormwater runoff is the primary source of water. An ephemeral
stream typically lacks the biological, hydrological, and physical characteristics commonly
associated with the continuous or intermittent conveyance of water.
Impervious Surface. Any material that significantly reduces and prevents natural infiltration of
water into the soil. Impervious surfaces include but are not limited to roofs, patios, balconies,
decks, streets, parking areas, driveways, sidewalks, and any concrete stone, brick, asphalt, or
compacted gravel surface.
Intermittent Stream. A well-defined channel that contains water for only part of the year,
typically during winter and spring when the aquatic bed is below the water table. The flow may
be heavily supplemented by Stormwater runoff. An intermittent stream often lacks the
biological and hydrological characteristics commonly associated with the conveyance of water.
Land -Disturbing Activity. Any use of the land by any person in recreational, industrial,

3U
educational, service, institutional, office, industrial, or commercial development, road
construction and maintenance that results in a change in the natural cover or topography or
alters the natural structure of the land mass and that causes or contributes to sedimentation.
Maintain or Maintenance. Any action necessary to keep stormwater control measures and
devices in proper working condition, so that such facilities shall continue to comply with the
standards of this chapter to prevent failure of stormwater control measures and devices and
functions as intended. Maintenance includes activities undertaken to prevent failure of
stormwater control measures and devices, and includes maintenance activities identified in
approved stormwater control plans and maintenance manuals, and the North Carolina Division
of Water Quality Stormwater Best Practices Manual, July 2007.
New Development. Any development for a project requiring site plan approval or similar
approvals by the NCGTP, which, in the case of office, institutional, commercial, or industrial
development will result in land disturbance of greater than one-half acre. New development
shall include redevelopment but shall not include agriculture, mining or forestry activities.
North Carolina Global TransPark (NCGTP). That entity created by enabling legislation in 1991
(NCGS Chapter 63A) to perform essential governmental and public functions related to
development of an air cargo facility in Kinston North Carolina. The NCGTP Authority Board (the
Authority) is the governing body for the TransPark.
Off -Site Stormwater Control Facilities. The overall design, construction and maintenance of
one (1) or more devices and measures and associated drainage easements, conduits, inlets,
channels, pipes and ditches, filters, buffers, bioretention areas, and ponds necessary to collect,
convey, store, and control stormwater runoff and pollutants from more than one (1)
development site. Stormwater control facilities serving contiguous properties consisting of
more than one (1) tenant site are examples of off -site stormwater control facilities.
On -Site Stormwater Control Facilities. The overall design, construction and maintenance of
one (1) or more devices and measures and associated drainage easements, conduits, inlets,
channels pipes, ditches, filters, buffers, bioretention areas, stormwater wetlands, and ponds
necessary to collect, convey, store, and control stormwater runoff and pollutants within and for
a single tenant site.
Perennial Stream. A well-defined channel that contains water year round during a year of
normal rainfall with the aquatic bed located below the water table for most of the year.
Groundwater is the primary source of water for a perennial stream, but it also carries
stormwater runoff. A perennial stream exhibits the typical biological, hydrological, and physical
characteristics commonly associated with the continuous conveyance of water.
Pre -Development Conditions. The land use, drainage, and impervious surface conditions
existing on the site at the time plans are submitted for approval.
Post -Development Conditions. Pre -development conditions together with the land use,
drainage and impervious conditions that would exist on the site if all proposed development
plans for the site are fully completed.
North Carolina Division of Quality Stormwater Best Practices Manual, July 2007. A manual
adopted by the NCGTP by reference, as fully set forth in this section which includes plan and
data submission requirements, presents design procedures and criteria for conducting natural,
hydrologic and hydraulic evaluations, best management practice designs, standards for
managing the volume and quality of stormwater runoff, and standards.
11

Regional Stormwater Control Facilities. The overall design, construction and maintenance of
measures and devices and associated drainage easements, conduits, inlets, channels, pipes,
ditches, filters, buffers, bioretention areas, and ponds necessary to collect, convey, store, and
control stormwater runoff and pollutants within or outside a development and for one (1) or
more developments, as shown on the NCGTP stormwater master plan and approved by the
North Carolina Division of Water Quality.
Riparian Surface Water. Actual surface water that is shown as a feature on either the most
recent version of (a) the Lenoir County soil survey map prepared by the Natural Resources
Conservation Service of the United States Department of Agriculture; or (b) the most recent
version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the
United States Geologic Survey (USGS) except for the following surface waters:

stream.
(2) Man-made ponds and lakes located outside natural drainage ways.
(3) Ephemeral (stormwater) streams.
Stormwater Master Plan. A conceptual plan approved by the NCGTP Authority and the North
Carolina Division of Water Quality, which establishes stormwater control policies and
recommendations for all land owned or controlled by NCGTP. This plan may be expanded as
additional property is acquired, or may include an entire watershed or region as an alternative
to individual site specific stormwater control plans. This expansion of jurisdiction will only be
implemented upon approval by the NCGTP Authority, with concurrence from the North
Carolina Division of Water Quality. The purpose of the stormwater master plan is to meet or
exceed stormwater requirements of the Neuse River Basin Nutrient Sensitive Waters
Management Strategy in a more coordinated and cost effective manner through the use of
regional stormwater control facilities as opposed to the exclusive use of on -site or off -site
stormwater control facilities.
Stormwater Control Plan. The set of drawings and other documents that comprise all of the
information and specifications for the drainage systems, structures, concepts, techniques,
measures and devices that will be used to control nitrogen loads and stormwater runoff on a
site specific basis as required by this chapter and the North Carolina Division of Water Quality
Stormwater Best Practices Manual, July 2007. Also included are the supporting engineering
calculations, input data for any computer analyses, and results of any computer analyses.
Section 3. Applicability
All new development within the NCGTP complex shall, prior to the approval of a site plan or
similar plan of any type, comply with the requirements of the Neuse River Basin Nutrient
Sensitive Waters Management Strategy as specified in 15A NCAC 2B .0235 and these
regulations herein. In addition, each new development will be required to submit a site specific
Stormwater Control Plan prior to commencement of construction. Where these requirements
conflict with or differ from other regulatory requirements including, but not limited to, the
NCGTP stormwater master plan or Lenoir County, the stricter of the requirements shall control.
It is the intent of the NCGTP Authority to regulate stormwater and tenant usage on a regional
or watershed basis. Initially, NCGTP will regulate tenants on lands owned and controlled by
NCGTP, with options to expand jurisdiction based on additional property acquisitions, or within
the defined watershed surrounding NCGTP. ' A stormwater master plan will define
7

implementation strategies. Any expansion of jurisdiction is subject to review by the North
Carolina Division of Water Quality.
Section 4. Nitrogen Control Requirements.
(a) Compliance with State Standards. No new development or expansion of an existing
development, use, facility, building, structure, nor any new or expanded vehicular surface area
shall contribute a nitrogen export load exceeding ten (10) pounds per acre per year per project
at an individual tenant site. Cumulative development loads will not exceed three and six -tenths
(3.6) pounds per acre per year for the entire NCGTP complex.
(b) Alternate Means of Compliance
(1) Utilize NCGTP Nitrogen Allocations. The NCGTP proposes to utilize current nitrogen
allocations for the entire NCGTP complex primarily to meet NCGTP facility and
infrastructural needs. Developers shall have the option of requesting access to
remaining NCGTP nitrogen allocations from the NCGTP Environmental Compliance
Officer. Access to and use of NCGTP nitrogen allocations is at the discretion of the
NCGTP Executive Director, with approval by the Authority, and may not exceed the
total allocation for the entire NCGTP complex.
(2) Payment to North Carolina Riparian Buffer Restoration Fund or other Third Party

NCGTP Stormwater Ordinance
On August 6, 2010 the Executive Committee of the NCGTP Board of Directors approved
revisions to the NCGTP Exclusive Development Ordinance, including the addition of the
Stormwater Control and Watercourse Buffer Ordinance (attached). As stated in Section 1, this
ordinance is intended to protect water quality in the Neuse River Basin from additional nitrogen
pollution generated from new development and to preserve existing riparian buffers in that basin.
To achieve these purposes, this section establishes performance standards that: 1) limit the
amount of nitrogen in stormwater runoff; 2) controls stormwater peak runoff rates; 3) promotes
the use of best management practices; and 4) protects existing riparian buffers.

C-1-5 Stormwater Control and Watercourse Buffer Ordinance �' '�""�
Section 1. Title; Purpose.
(a) Title. This chapter shall constitute and be known and may be cited as the "Stormwater
Control and Watercourse Buffer Ordinance" of the North Carolina Global TransPark (NCGTP).
(b) Purpose. This section is intended to protect water quality in the Neuse River Basin from
additional nitrogen pollution generated from new development and to preserve existing
riparian buffers in that basin. To achieve these purposes, this section establishes performance
standards that: limit the amount of nitrogen in stormwater runoff; controls Stormwater peak
runoff rates; promotes the use of best management practices; and protects existing riparian
buffers.
Section 2. Definitions.
As used in this chapter, unless the context clearly indicates otherwise, the terms, phrases and
words, and their derivatives, have the meaning given herein:
Best Management Practice or BMP. Stormwater and runoff pollution control devices or
practices designed to reduce -the amount of flow or pollutants contained in discharges to the
Stormwater conveyance system and receiving waters, which meet standards outlined in the
North Carolina Division of Water Quality Stormwater Best Practices Manual, July 2007.
Buffer. An area of natural or planted vegetation through which stormwater runoff flows in a
diffuse manner so that the runoff does not become channelized and which provides for
infiltration of the runoff and filtering of pollutants. The buffer is measured landward from the
normal pool elevation of impounded structures and from the bank of each side of streams and
rivers.
Environmental Compliance Officer. A person or company retained by NCGTP to review and
implement the NCGTP stormwater master plan. All NCGTP development plans must be
submitted to the Environmental Compliance Officer for review and approval before
commencing construction.
Ephemeral (Stormwater) Stream. A feature that carries only stormwater in direct response to
precipitation with waters flowing only during and shortly after large precipitation events. An
ephemeral stream may or may not have a well-defined channel, the aquatic bed is always
above the water table, and stormwater runoff is the primary source of water. An ephemeral
stream typically lacks the biological, hydrological, and physical characteristics commonly
associated with the continuous or intermittent conveyance of water.
Impervious Surface. Any material that significantly reduces and prevents natural infiltration of
water into the soil. Impervious surfaces include but are not limited to roofs, patios, balconies,
decks, streets, parking areas, driveways, sidewalks, and any concrete stone, brick, asphalt, or
compacted gravel surface.
Intermittent Stream. A well-defined channel that contains water for only part of the year,
typically during winter and spring when the aquatic bed is below the water table. The flow may
be heavily supplemented by stormwater runoff. An intermittent stream often lacks the
biological and hydrological characteristics commonly associated with the conveyance of water.
Land -Disturbing Activity. Any use of the land by any person in recreational, industrial,
5

H
educational, service, institutional, office, industrial, or commercial development, road
construction and maintenance that results in a change in the natural cover or topography or
alters the natural structure of the land mass and that causes or contributes to sedimentation.
Maintain or Maintenance. Any action necessary to keep stormwater control measures and
devices in proper working condition, so that such facilities shall continue to comply with the
standards of this chapter to prevent failure of stormwater control measures and devices and
functions as intended. Maintenance includes activities undertaken to prevent failure of
stormwater control measures and devices, and includes maintenance activities identified in
approved stormwater control plans and maintenance manuals, and the North Carolina Division
of Water Quality Stormwater Best Practices Manual, July 2007,
New Development. Any development for a project requiring site plan approval or similar
approvals by the NCGTP, which, in the case of office, institutional, commercial, or industrial
development will result in land disturbance of greater than one-half acre. New development
shall include redevelopment but shall not include agriculture, mining or forestry activities.
North Carolina Global TransPark (NCGTP). That entity created by enabling legislation in 1991
(NCGS Chapter 63A) to perform essential governmental and public functions related to
development of an air cargo facility in Kinston North Carolina. The NCGTP Authority Board (the
Authority) is the governing body for the TransPark.
Off -Site Stormwater Control Facilities. The overall design, construction and maintenance of
one (1) or more devices and measures and associated drainage easements, conduits, inlets,
channels, pipes and ditches, filters, buffers, bioretention areas, and ponds necessary to collect,
convey, store, and control stormwater runoff and pollutants from more than one (1)
development site. Stormwater control facilities serving contiguous properties consisting of
more than one (1) tenant site are examples of off -site stormwater control facilities.
On -Site Stormwater Control Facilities. The overall design, construction and maintenance of
one (1) or more devices and measures and associated drainage easements, conduits, inlets,
channels pipes, ditches, filters, buffers, bioretention areas, stormwater wetlands, and ponds
necessary to collect, convey, store, and control stormwater runoff and pollutants within and for
a single tenant site.
Perennial Stream. A well-defined channel that contains water year round during a year of
normal rainfall with the aquatic bed located below the water table for most of the year.
Groundwater is the primary source of water for a perennial stream, but it also carries
Stormwater runoff. A perennial stream exhibits the typical biological, hydrological, and physical
characteristics commonly associated with the continuous conveyance of water.
Pre -Development Conditions. The land use, drainage, and impervious surface conditions
existing on the site at the time plans are submitted for approval.
Post -Development Conditions. Pre -development conditions together with the land use,
drainage and impervious conditions that would exist on the site if all proposed development
plans for the site are fully completed.
North Carolina Division of Quality Stormwater Best Practices Manual, July 2007. A manual
adopted by the NCGTP by reference, as fully set forth in this section which includes plan and
data submission requirements, presents design procedures and criteria for conducting natural,
hydrologic and hydraulic evaluations, best management practice designs, standards for
managing the volume and quality of stormwater runoff, and standards.
0

Regional Stormwater Control Facilities. The overall design, construction and maintenance of
measures and devices and associated drainage easements, conduits, inlets, channels, pipes,
ditches, filters, buffers, bioretention areas, and ponds necessary to collect, convey, store, and
control stormwater runoff and pollutants within or outside a development and for one (1) or
more developments, as shown on the NCGTP stormwater master plan and approved by the
North Carolina Division of Water Quality.
Riparian Surface Water. Actual surface water that is shown as a feature on either the most
recent version of (a) the Lenoir County soil survey map prepared by the Natural Resources
Conservation Service of the United States Department of Agriculture; or (b) the most recent
version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the
United States Geologic Survey (USGS) except for the following surface waters.
(1) Man-made channels, such as ditches and canals, other than a modified natural
stream.
(2) Man-made ponds and lakes located outside natural drainage ways.
(3) Ephemeral (stormwater) streams.
Stormwater Master Plan. A conceptual plan approved by the NCGTP Authority and the North
Carolina Division of Water Quality, which establishes stormwater control policies and
recommendations for all land owned or controlled by NCGTP, This plan may be expanded as
additional property is acquired, or may include an entire watershed or region as an alternative
to individual site specific stormwater control plans. This expansion of jurisdiction will only be
implemented upon approval by the NCGTP Authority, with concurrence from the North
Carolina Division of Water Quality. The purpose of the stormwater master plan is to meet or
exceed stormwater requirements of the Neuse River Basin Nutrient Sensitive Waters
Management Strategy in a more. coordinated and cost effective manner through the use of
regional stormwater control facilities as opposed to the exclusive use of on -site or off -site
stormwater control facilities.
Stormwater Control Plan. The set of drawings and other documents that comprise all of the
information and specifications for the drainage systems, structures, concepts, techniques,
measures and devices that will be used to control nitrogen loads and stormwater runoff on a.
site specific basis as required by this chapter and the North Carolina Division of Water Quality
Stormwater Best Practices Manual, July 2007. Also included are the supporting engineering
calculations, input data for any computer analyses, and results of any computer analyses.
Section 3. Applicability
All new development within the NCGTP complex shall, prior to the approval of a site plan or
similar plan of any type, comply with the requirements of the Neuse River Basin Nutrient
Sensitive Waters Management Strategy as specified in 15A NCAC 213 .0235 and these
regulations herein. In addition, each new development will be required to submit a site specific
Stormwater Control Plan prior to commencement of construction. Where these requirements
conflict with or differ from other regulatory requirements including, but not limited to, the
NCGTP stormwater master plan or Lenoir County, the stricter of the requirements shall control.
It is the intent of the NCGTP Authority to regulate stormwater and tenant usage on a regional
or watershed basis. Initially, NCGTP will regulate tenants on lands owned and controlled by
NCGTP, with options to expand jurisdiction based on additional property acquisitions, or within
the defined watershed surrounding NCGTP. A stormwater master plan will define

implementation strategies. Any expansion of jurisdiction is subject to review by the North
Carolina Division of Water Quality.
Section 4. Nitrogen Control Requirements.
(a) Compliance with State Standards. No new development or expansion of an existing
development, use, facility, building, structure, nor any new or expanded vehicular surface area
shall contribute a nitrogen export load exceeding ten (10) pounds per acre per year per project
at an individual tenant site. Cumulative development loads will not exceed three and six -tenths
(3.6) pounds per acre per year for the entire NCGTP complex.
(b) Alternate Means of Compliance
(1) Utilize NCGTP Nitrogen Allocations. The NCGTP proposes to utilize current nitrogen
allocations for the entire NCGTP complex primarily to meet NCGTP facility and
infrastructural needs. Developers shall have the option of requesting access to
remaining NCGTP nitrogen allocations from the NCGTP Environmental Compliance
Officer. Access to and use of NCGTP nitrogen allocations is at the discretion of the
NCGTP Executive Director, with approval by the Authority, and may not exceed the
total allocation for the entire NCGTP complex.
(2) Payment to North Carolina Riparian Buffer Restoration Fund or other Third Parry
Mitigation Providers. Developers shall have the option of offsetting their nitrogen
export load limitations of subsection (a) above by paying monies to the North Carolina
Riparian Buffer Restoration Fund based on the latest fee adopted by the State or
engage other third party mitigation providers approved by NCGTP and the North
Carolina Division of Water Quality. A one-time offset payment may be paid to bring the
nitrogen export load down from ten (10) pounds per acre per year to three and six -
tenths (3.6) pounds per acre per year. Installation of NCGTP approved on -site
stormwater control facilities or payments or a combination of both may be used.
(3) Stormwater Master Plan. Developments that comply with the NCGTP stormwater
master plan approved for NCGTP may be exempted from the requirements of
subsection (a) above. Compliance with the stormwater master plan shall include the
installation within the development of all stormwater control measures shown in the
stormwater master plan, approved use of regional stormwater control facilities,
payment of fees in lieu of installation when allowed by NCGTP or the North Carolina
Division of Water Quality, use of NCGTP nitrogen allocations if allowed by the NCGTP,
and payment of any applicable drainage fees.
(c) Procedures. The nitrogen export calculations shall be made using procedures outlined in
the North Carolina Division of Water Quality Stormwater Best Practices Manual, July 2007.
(d) Time of Submission. The applicant shall submit nitrogen export calculations for pre -
development and post -development conditions at each tenant site or for each project and
demonstrate compliance with this section prior to the approval of a site plan of any type, as
part of plan submission. All calculations are to be reviewed by the NCGTP Environmental
Compliance Officer.
(e) Approved BMPs.
8

lZi
(1) The Best Management Practices that may be used to reduce nitrogen in
stormwater runoff include but are not limited to the following: wet detention ponds,
constructed wetlands, open channel practices (water quality swales), riparian buffers,
vegetated filter strips with level speader, bioretention cells (rain gardens), and sand
filters. The BMP nitrogen removal efficiencies shall be as listed in the North Carolina
Division of Water Quality Stormwater Best Practices Manual, July 2007. Use of all BMP
measures is subject to review and approval by the NCGTP Environmental Compliance
Officer.
(2) Proprietary or Demonstration BMPs must be approved by the NCGTP
Environmental Compliance Officer, with concurrence from the North Carolina -Division
of Water Quality for general use and must be designed in accordance with any
guidelines established by the Division, and any manufacturer's guidelines and
specifications that are not inconsistent with the Division's guidelines.
Section 5. Peak Runoff Control Requirements.
(a) Standards. New development must discharge the storage volume at a rate equal to or less
than the pre -development peak runoff rate for the one year, 24-hour storm event. If the post -
development peak runoff rate does exceed pre -development rates, on -site stormwater control
facilities shall be provided such that there is no net increase.
(b) Procedures_. The peak flow calculations shall be made using procedures outlined in the
North Carolina Division of Water Quality Stormwater Best Practices Manual, July 2007.
(c) Time of Submission. The applicant shall submit peak flow calculations for the pre -
development and post -development conditions prior to the approval of a site plan of any type
as part of plan submission. All calculations are subject to review and approval by the NCGTP
Environmental Compliance Officer.
(d) Exemptions. New development is exempted from these peak runoff control requirements if
the overall impervious surface within the development is less than fifteen (15) percent and the
remaining pervious portions of the site are utilized to the maximum extent practical to convey
and control the stormwater runoff, as determined by the NCGTP Environmental Compliance
Officer.
(e) Stormwater Master Plan. Developments that comply with the stormwater master plan
approved for NCGTP may be exempted from the requirements of section (a) above. Compliance
with the NCGTP stormwater master plan shall include the installation within the development
of all on -site stormwater control facilities shown in the stormwater master plan, payment of
fees in lieu of installation, , and payment of any applicable drainage fees.
Section 6. Stormwater Control Plan.
(a) General Requirements. The Stormwater Control Plan for each facility shall be designed
to meet the requirements of the Neuse River Basin - Nutrient Sensitive Waters Management
Strategy (15A NCAC 2B .0235 4(a)(i) and (ii). All structural BMPs shall be designed and
maintained in accordance with the North Carolina Division of Water Quality Stormwater Best
Practices Manual, July 2007.
(b) Maintenance Manual and Budget. The Stormwater Control Plan shall include an
operation and maintenance manual and proposed budget.The maintenance manual shall
contain a narrative describing each installed measure and device and design specifications. The
0

maintenance manual shall indicate for each installed measure and device what operation and
maintenance actions are needed and what specific quantitative criteria will be used to
determine when these actions will be taken. The budget shall include both annual costs, and a
fund for structural and vegetative replacement, periodic sediment and contaminant removal,
major repairs and replacement.
Section 7. Buffer Requirements.
(a) Buffer. The applicant shall show on all site development plans, 50-foot wide riparian buffers
directly adjacent to riparian surface waters (perennial and intermittent streams, lakes, ponds
and estuaries) as defined in Section 2 unless exempted by the North Carolina Division of Water
Quality. Exemptions will be coordinated between the NCGTP Environmental Compliance
Officer and the Division of Water Quality and subsequently documented.
(b) Calculation Next To Riparian Surface Water. For streams, ponds, lakes, or similar
impoundments, the buffer shall begin at the most landward limit of the normal water level (top
of the bank for intermittent and perennial streams) and extend landward, measured
horizontally on a line perpendicular to the surface water.
(c) No Impact/Determination. The applicant shall demonstrate that the new development
does not impact the Neuse buffer. Land disturbing activities that may impact Neuse Buffer
systems are subject to review by the NCGTP Environmental Compliance Officer and will be
coordinated with the North Carolina Division of Water Quality prior to impact approval.
Section S. Incorporation of the North Carolina Division of Water Quality Stormwater Best
Practices Manual, July 2007.

Subject:
RE. GTP Starmwater permit
�- 63 70
Good Afternoon Ron & Mike:
Here are some comments/questions about the draft permit & Ron's follow-up package:
The Draft Permit (from Mike's 6/8/10 email): '
1) Part I, Permit Coverage: need a specific reference to Oil/Water Separators, need to decide if separate NPDES
permit will be required, Military Base permits have language re oil/water separators that might be appropriate
for GTP permit.
2) Part I, (4): GTP needs to provide list of all current tenants by type & SIC #; DWQ can then decide, with help from
GTP, which if any current tenants need separate NCS, or NCG permits.
3) Part 11, Section A, (7): re post -construction site runoff control program — Sect B, (2) (e) gives GTP 24 months to'
implement; we should reconsider this "time lapse", Structural BMP's have already been installed at GTP;
probably to meet Neuse NSW requirements. We should not #ait 2 years before we require BMPs for new
development.
4) Section C, Monitoring Requirements: this section speaks to monitoring sw outfalls where deicing occurs; which
is only (1) of several SDO. This approach effectively eliminates analytical sampling for all other SDO's. If the
waiver stipulated in Section C,(1)(f) is exercised, then No monitoring will occur. To be consistent with other
permits, I think this permit should require some monitoring from the other SDO's, and/or require some
monitoring from this designated deicing outfall, even in the absence of deicing operations. Shouldn't BM levels
be required for the other SDO's ?
5) Section C, (4)(a) Qualitative Monitoring: The visual inspections (assuming done properly) at all the SDO's on a
quarterly basis, is very basic & probably the most cost effective way to monitor what kind of sw impacts'a facility
may be having on surrounding waters. We need to remove some of the "open-ended" language here and send
a clear message to the permittee, "go look at your SDO's regularly".
6) Section C,(4)(e): qualitative monitoring at the "deicing outfail" should be conducted during a "measurable
runoff event" and within 60 minutes following the deicing activities.
7) Section D, (1): requires annual compliance evaluation of entire facility; take the specific reference to deicing out
of No. 1 and place it as a separate item in (2)(g). As worded, it conditions annual compliance evaluations to
deicing & inclement weather.
8) Section E: "average of 4 quarterly monitoring events" to determine bench markk-exceedance ?? I have not seen
this wording before; does not seem appropriate to average quarterly monitoring results; should be based on (2)
consecutive events that exceed BM levels, just as stipulated in other permits.
9) Part IV,(3): Deicing Usage: annual usage rates may not tell us everything we want to know. Needs to require
specific (daily) usage rates be recorded.
10) Part IV,(12): This definition is right on target; it should be included in all NPDES permits. Reporting spills should
be to 24 hour State Emergency Response Center 800 # and/or appropriate Regional Office during normal
business hours.
Ron, I reviewed the figures & O/M documents you sent by email 12/13/10. Very briefly:
(1) I understand the SW Master Plan is being "worked on"; what is the time table for completion ?
(2) Oil/Water Separator probably needs separate NPDES, or we need to decide if it can be covered under this
individual NCS permit ? are there other O/W separators, existing or proposed ?

(3) The O&M documents need to be drafted with specifics for each of the identified BMP's . You could use the
0&M templates from our website; if slight modifications are needed to accommodate GTP circumstances, that
may be OK.
(4) Each BMP needs design specs, proper O&M with inspection frequencies, and owner/engineers inspection to .
determine they are properly built. '
(5) Inspections of BMP's should be amended from annually; along the lines of monthly, or quarterly.
(6) "Stormwater Control & Watercourse Buffer Ordinance": This whole document appears to be tailored to meet
requirements of Neuse SW & Buffer Rules; while I understand that approach; this document needs to be
amended/expanded to include requirements of NPDES, Phase 2 rules.
Ron, I think a follow-up meeting with you, Mike & I would be helpful in clearing up any remaining questions. Mike, I
don't know the status of the draft permit/public notice, but we probably need to talk soon.

PART I PERMIT COVERAGE
1. During the period beginning on the effective date of the permit and lasting until expiration, North
Carolina Global TransPark Authority is authorized to discharge stormwater from the storm sewer
system, construction activities, and industrial activities identified herein, to receiving waters,
designated as Wheat Swamp, Stonyton Creek, Briery Run and Gum Swamp Drainage Basins, in
the Neuse River Basin. Such discharge will be controlled, limited and monitored in accordance
with the permittee's Comprehensive Stormwater Management Program Report, herein referred to
as the Stormwater Management Plan (SWMP). The SWMP includes components of the
permittee's NPDES Stormwater Permit Application, NPDES Stormwater Permit Application
Comprehensive Stormwater Management Program Report and any approved modifications, and
the permittee's industrial stormwater control plan. The requirements in this permit apply to
stormwater discharges associated with industrial activity from Air Transportation facilities
identified by the SIC Codes in Major Group 45, namely air transportation, scheduled, and air
courier (SIC 4512 and 4513); air transportation, non scheduled SIC 4522); airports, flying fields,
except those maintained by aviation clubs, and airport terminal services including: air traffic
control, except government; aircraft storage at airports;; airbiitupholstery repair; airfreight
handling at airports; airport hangar rental; airport leasing, if o0g0mg airport; airport terminal
services; and hangar operations; and airporf and aircraft,service and maintenance including:
aircraft cleaning and janitorial service; aircraft servicing/repairing, except on a factory basis;
vehicle maintenance shops; material handlingefacilities;;equipment clearing operations; and
airport and aircraft deicing/anti-icing. (SIC�4581?) The types of activities that Air Transportation
facilities are primarily engaged in are:
1:
(a) Servicing, repairingor maiiitaining;'acircraft and ground vehicles,
(b) Equipment clean ing,and;mamtenaace (including vehicle and equipment rehabilitation
mechanical repairs, painting, fueling, and lubrication), and
(c) Deicinglanti-icingyoperationsn Deicing will generally be used to imply both deicing
(removing frost,5now or ice) and anti -icing (preventing accumulation of frost, snow or
ice) activities. /`:i
All discharges authorized"heiein shall be adequately managed in accordance with the terms and
conditions of this permit. Any other point source discharge to surface waters of the state is
prohibited unless it is an allowable non-stormwater discharge or is covered by another permit,
authorization, or approval.
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.
4. This permit covers activities associated with the discharge of stormwater from the storm sewer
system and industrial activities identified herein within the jurisdictional area of the permittee as
described in the approved SWMP. The permit applies to current and future jurisdictional areas
of the permittee, as well as areas that seek coverage under this permit through inter -local or other
similar agreements with the permittee. Agreements for coverage under this permit must be
approved by the Division of Water Quality, herein referred to as the Division. If a tenant
obtains authorization under this permit and develops a Plan for discharges from the
commercial tenant's own areas of the airport, that Plan must be coordinated and
integrated with the Plan for the entire airport. The Director may require a tenant to apply
for and obtain an individual permit or an alternative General Permit for industrial
activities outside the scope of this permit per Part I - Permit Coverage, paragraph 1 above.
Part I Page 1 of 3

Permit No. NCS000516
The Division may deny or revoke coverage under this permit for separate entities and require
independent permit coverage as deemed necessary. In addition, the permittee may petition the
Division to revoke or deny coverage under this permit for specific entities.
6. Under the authority of Section 402(p) of the Clean Water Act and implementing regulations 40
CFR Part 122, 123 and 124, North Carolina General Statutes 143-215.1 and Session Law 2006-
246 and in accordance with the approved SWMP, all provisions contained and referenced in the
SWMP are enforceable parts of this permit. The permittee will develop and implement its
approved SWMP in accordance with Section 402(p)(3)(B) of the Clean Water Act, provisions
outlined by the Director, and the provisions of this permit.
This permit includes provisions to ensure that discharges do not cause or contribute to
exceedances of water quality standards. This permit sets technology -based limitations in the form
of Best Management Practices that apply to all pollutants associated with industrial activity. The
permit requires the development and proper implementation of, ,the SWMP. The purpose of the
SWMP is to reduce the discharge of pollutants from,the storrmwater sewer system to the
maximum extent practicable, to protect water quality, anclAo satisfy tt a applicable water quality
requirements of the Clean Water Act. Implementation;of best management practices consistent
with the provisions of the SWMP constitutes'compliance with the standard of reducing pollutants
to the maximum extent practicable. Successive it" rations of the SWMP and other components of
X F-W.
this permit will be driven by the objective ofassuringthat discharges do not cause or contribute
to the violation of water quality standards,Arough the -expansion and tailoring of management
measures within the scope of the SWMP;
8. If at any time the Division determine"(s)o that;the,permittee's discharge causes or contributes to an
exceedance of applicable water qualtty:standards, the permittee must take corrective actions and
conduct follow-up monitoring..I.f the Division makes the determination that the permittee's
discharge causes or contributes to�ari exceedance of a water quality standard, the permittee must
comply with any requirements or schedules, including submitting additional information
concerning the potential cause of the exceedance.
9. The permit authorizes the -point source discharge of stormwater runoff from the storm sewer
system and industrial activities identified herein. In addition, discharges of non-stormwater are
also authorized through the storm sewer system of the permittee if such discharges are;
(a) Permitted by, and in compliance with, another NPDES discharge permit including
discharges of process and non -process wastewater, and stormwater associated with
industrial activity; or
(b) Determined to be incidental non-stormwater flows that do not significantly impact water
quality and may include:

12 If a wasteload allocation (WLA) has been established that applies to the permittee's discharge,
the permittee must develop and implement all necessary controls to meet that allocation. The
permittee must verify that their discharge complies with the WLA through the appropriate
discharge monitoring. Failure to comply with a relevant WLA is a violation of this permit. If the
permittee has properly complied with the requirements of this permit, and finds that the
applicable TMDL does not specify a wasteload allocation or other requirements either
individually or categorically for the permittee's discharge (including disallowing such
discharge), compliance with this permit will be deemed adequate to meet the requirements of the
TMDL.
If a TMDL has not been established that applies to the permittee's discharge the permittee must
comply with the requirements of this permit and any additional conditions stipulated by the
Division. If the permittee has properly complied with all such requirements then compliance with
this permit will be deemed adequate to meet the requirements for discharging to an impaired

SWMP and to assist in knowing when additional corrective action may be necessary to protect
water quality. If the average of four quarterly;discharge samples exceed a benchmark
concentration the permittee must review their SWMP and BMPs to determine whether any
improvement or additional controls''are needed to reduce that pollutant in the stormwater
discharge(s). failure to
�undertakend document the review, take the necessary corrective
actions, or follow notiflcat�on prgcedures stipulated in this permit are violations of this permit.
SECTION B: STORMWATER MANAGEMENT PROGRAM
1. The permittee musffdevelop,,implement, and enforce a storm water management program
KJ-designed to reduce the discharge of pollutants from the MS4 to the maximum extent practicable
n�rq
(MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the
l Clean Water Act. The storm water management program should include management practices;
control techniques and system, design, and engineering methods; and such other provisions as the
�f✓ permitting authority determines appropriate for the control of such pollutants. The storm water
management program must include the following information for each of the six minimum
control measures described in Section B.2 of this permit:
(a) The best management practices (BMPs) that the permittee or another entity will
implement for each of the storm water minimum control measures;
(b) The measurable goals for each of the BMPs including, as appropriate, the months and
years in which the permittee will undertake required actions, including interim
milestones and the frequency of the action; and
(c) The person or persons responsible for implementing or coordinating the BMPs for the
stormwater management program.

(vi) Address the following categories of non -storm water discharges or flows (i.e.,
illicit discharges) only if identified as significant contributors of pollutants to the
MS4: water line flushing, landscape irrigation, diverted stream flows, rising
ground waters, uncontaminated ground water infiltration (as defined at 40 CFR
§35.2005(20)), uncontaminated pumped ground water, discharges from potable
water sources, foundation drains, air conditioning condensation, irrigation water,
springs, water from crawl space pumps, footing drains, lawn watering, individual
residential car washing, flows from riparian habitats and wetlands, dechlorinated
swimming pool discharges, and street wash water (discharges or flows from fire
fighting activities are excluded from the effective prohibition against non -storm
water and need only be addressed where they are identified as significant sources
of pollutants to waters of the United States).
(vii) The permittee may also develop a list of other similar occasional incidental non -
storm water discharges (e.g. non-commercial or charity car washes, etc.) that will
not be addressed as illicit discharges. These non -storm water discharges must not

be reasonably expected (based on information available to the permittees) to be
significant sources of pollutants to the Municipal Separate Storm Sewer System,
because of either the nature of the discharges or conditions established for
allowing these discharges to the MS4 (e.g., a charity car wash with appropriate
controls on frequency, proximity to sensitive waterbodies, BMPs on the wash
water, etc.). The permittee must document in the SWMP any local controls or
conditions placed on the discharges. The permittee must include a provision
prohibiting any individual non -storm water discharge that is determined to be
contributing significant amounts of pollutants to the MS4.

(vii) Spill Prevention and Response Plan. The Spill Prevention and Response Plan
(SPRP) shall incorporate an assessment of potential pollutant sources based on a
materials inventory of the facility. Facility personnel (or the team) responsible
for implementing the SPRP shall be identified in a written list incorporated into
the SPRP. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through
spills or exposure of materials associated with the facility operations. The SPRP
must be site stormwater specific. Therefore, an oil Spill Prevention Control and
Countermeasure plan (SPCC) may be a component of the SPRP, but may not be
sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference
into the SPRP. Response procedures must include notification of appropriate
facility personnel, emergency agencies, and regulatory agencies, and procedures
for stopping, containing and cleaning up spills. Employees who may cause,
detect or respond to a spill or leak must be,;lrained in these procedures and have
necessary spill response equipment available. Include contact information for
individuals and agencies that must be,nat'ified inAe event of a spill in the Plan

(D) Evaluate whether excessive application of deicing chemicals occurs and
adjust as necessary, consistent with considerations of flight safety.
(E) Develop and implement a plan for the minimization of the release of
materials used for de-icing into the stormwater system. This plan shall
address:
• The current use and practices employed at the airport for the control
and minimization of entry of the de-icing materials into the
stormwater system; and
• The means that may be practicable for modifying current use and
practices to collect the runoff that occurs during and following the
application of the de-icing materials.
• Feasible alternatives to the use of urea and glycol -based deicing
chemicals to reduce thpggregate amount of deicing chemicals used
and/or lessen the'ienvronmental3ampact, consistent with
considerations of AQt�safety.
A�.^'.IItEi
• Airport authcri ices mus determine annually the usage rate o
deicinglanti-icingah�micals at their facility. The total amount of
deicinglanti-icing chemicals used at an airport facility is the
cumul�aiv eamount used by the airport authority and each tenant of
the Airport facility. In determining the fluid amounts of deicinglanti-
icingchemicals used at a facility, operators should use the pre-
dilution�;volume.
(vi) Prepare estimates of annual pollutant loadings discharged to storm sewer
systems or surface waters resulting from discharges of spent deicing/anti-icing
chemicals"from the facility. The loading estimates shall reflect the amounts of
"UX.40—
deicing/anti-icing chemicals discharged to separate storm sewer systems or
surface waters.
SECTION C: MONITORING REQUIItEMENTS
Benchmark Monitoring where Deicing/Anti-icing Activities Occur
(a) The permittee must monitor those outfalis from the airport facility that collect runoff
from areas where deicing/anti-icing activities occur (SIC 4512-4581) for all benchmark

time period provided a deicing event occurs, except as provided in Part 1I Section C,
Paragraph 3.
(c) Submit results from all benchmark monitoring to the Division.
(d) If the monitoring values exceed the benchmark the permittee must review their SWMP
within 14 days to determine if it satisfies the requirements of this permit. The permittee
must document the date and findings of their review. If the permittee determines that the
SWMP satisfies the requirements of this permit, the permittee must document the
justification for this determination. If the permittee determines that the SWMP does not
satisfy the requirements of Part II the permittee must initiate corrective action.
(f) The permittee may exercise a waiver of�the benchmark monitoring requirements at a
facility that is inactive and unstaffed, as long as there arJno industrial materials or
activities exposed to stormwater. Iftliepermitteeexercises this waiver, the permittee
must maintain a certification with the`S,WMP stating that the site is inactive and
unstaffed, and that there are no induArria1,materials or activities exposed to stormwater.

The permittee must sign and certifythellwai'�er.
(g) Where two or more outfalls,discharge substantially identical effluents, based on
similarities of the industrial activities�lignificant materials, size of drainage areas, and
n ^If r
stormwater management practices.occurring within the drainage areas of the outfalls, the
permittee may conduct visual,monitoring of the discharge at just one of the outfalls and
report that the results'also apply to the substantially identical outfall(s), provided the
permittee documents in the SWMP the following: locations of the outfalls, why the
outfalls are expected to discharge substantially identical effluents, estimates of the size
of the drainage area (m square feet) for each of the outfalls, and an estimate of the runoff
coefficient•of the'dr'ainage areas (low: under 40 percent; medium: 40 to 65 percent; high:
K� _'-
above 65 percent).
2. Discharges to Impaired Receiving Monitoring is required for discharges to impaired waters
unless the permittee documents that there is no exposure of the pollutant of concern to
stormwater at the permittee's site.
(a) The permittee must submit results from all monitoring to the Division. Discharge
Monitoring Reports shall be delivered to the Division no later than 30 days from the date
the facility receives the sampling results from the laboratory.
(b) For discharges that are conveyed directly or indirectly to impaired waters, monitoring for
the pollutant of concern must be conducted at a minimum of once each permit year
throughout the term of the permit. This monitoring requirement is waived after one year
if the pollutant of concern is not detected in the permittee's stormwater discharge.
(c) For discharges that are conveyed directly or indirectly to waters for which EPA has
approved or established a TMDL with a wasteload allocation applicable to the
permittee's discharge (either specifically or categorically), monitoring for the wasteload
allocation pollutant of concern must be conducted, consistent with any instructions in
TMDL documentation. If the TMDL documentation does not specify monitoring

requirements, monitoring for the pollutant of concern must be conducted at a minimum
ofonce each permit year throughout the term of the permit, unless this permit already
assigns the permittee's discharge a benchmark for the pollutant of concern, in which case
the permittee must follow the benchmark monitoring schedule. The monitoring year
begins on the day the permittee's discharge is authorized. This monitoring must be
conducted in addition to all other monitoring requirements prescribed in this permit.
Monitoring of a pollutant of concern for which the discharge has been assigned a
wasteload allocation cannot be waived unless the WLA is specified only in terms of
BMPs, in which case the monitoring requirement is waived after one year if the pollutant
of concern is not detected in the stormwater discharge and the permittee documents that
the permittee has adopted the required BMPs.
Monitoring Instructions
(a) The permittee must sample in accordance with thefollowing provisions:
i. Take a minimum of one grab sample:fidaa discharge resulting from a storm

The 72-hour storm interval isSwaive¢d, when the preceding measurable storm did
not yield a measurable discharge, or, ifyou are able to document that less than a
72-hour interval is representatimfor local storm events during the sampling
period. '
ii. Take the+grab sample during the first 30 minutes of the discharge. If it is not
possibWtutakeith". sample during the first 30 minutes, sample during the first

Qualitative Monitoring Requirements
(a) The permittee must perform and document quart visual examination of a
stormwater discharge associated with industrial activity fro each outf 1, except as
provided for in Part II.C.3(c), Adverse Weather Conditions. The visual examination must
be made during daylight hours. If no storm event resulted in runoff during daylight hours
from the facility during a monitoring quarter, the permittee is excused from the visual
monitoring requirement for that quarter, provided the permittee documents that no runoff
occurred.
(b) Qualitative monitoring requires a visual inspection of each stormwater outfall regardless
of representative outfall status. Qualitative monitoring is for the purpose of evaluating
the effectiveness of the SWMP and assessing new sources of stormwater pollution. No
analytical tests are required. Qualitative monitoring shall be performed at each
f \ 141
stormwater discharge outfall regardless of representative outfall status.. -Visual
examinations must be made on samples c 11-cted within.the first minute (or as soon
r�
thereafter as practical, but not to exce r le r)"ofwhen the runoff or snowmelt begins
discharging form the outfall. All samples must be collected from a storm event discharge
that is greater than 0.1 inch in magn✓tiid`e�arid,that occurs at least 72 hours from the
previously measurable (greater thad O?`t inch rainfall) storm event. The 72-hour storm
v
interval is waived when the preceding measurable storm did not yield a measurable
discharge, or if it can be documented that -less than a 72-hour interval is representative
for local storm events during'�the'sampling period. The examination must document
observations of eolor, odor, clairity'-:floating solids, settled solids, suspended solids,
foam, oil sheen,' and other obvious indicators of stormwater pollution.
.,fix, ,,,�
(c) In the event an,atypicaUcondition is noted at a stormwater discharge outfall, the
permittee shall documentrhe suspected cause of the condition and any actions taken in
response to the discovery. This documentation will be maintained with the SWMP.
(d) Visual examination reports must be maintained onsite with the SWMP. The report must
include the examination date and time, inspection personnel, nature of the discharge (i.e.,
runoff or snow melt), visual quality of the stormwater discharge (including observations
of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen,
and other obvious indicators of stormwater pollution), and probable sources of any
observed stormwater contamination.
(e) All qualitative monitoring will be performed four times per year, once in the periods of
January —March; April -- June; July — September; and October— December. In the
January — March period the qualitative monitoring shall be performed when de- II
icing/anti-icing is occurring, when possible. '1k AQ- 4,6,,`T otcuy-5 y7
(f) If the permittec's qualitative monitoring indicates either that existing stormwater BMPs
are ineffective, or that significant stormwater contamination is present, the permittee
shall investigate potential causes, evaluate the feasibility of corrective actions, and
implement those corrective actions appropriate.
(g) The permittee may exercise a waiver of the visual monitoring requirements at a facility
that is inactive and unstaffed, as long as there are no industrial materials or activities
exposed to stormwater. If the permittee exercises this waiver, the permittee must
Part II Page 12 of 15

Permit No. NCS000516
maintain a certification stating that the site is inactive and unstaffed, and that there are no
industrial materials or activities exposed to stormwater. The permittee must sign and
certify the waiver.
Part 11 Page 13 of 15

Permit No. NCS000516
SECTION D: COMPLIANCE EVALUATION OF INDUSTRIAL ACTIVITIES
1. The permittee must conduct a comprehensive site compliance evaluation of airport facilities
subject to industrial stormwater permitting requirements at least once a year. Conduct annual site
compliance evaluations during periods of actual deicing operations. If not practicable during
U/ active deicing or the weather is too inclement, conduct annual site compliance evaluations when
deicing operations are likely to occur and the materials and equipment for deicing are in place.
2. Inspections must cover all the areas where industrial materials or activities are exposed to
stormwater, along with areas where spills and leaks have occurred in the past 3 years. Inspectors
must examine the following:
(a) Industrial materials, residue or trash that may have or could come into contact with
stormwater;
(b) Leaks or spills from industrial equipment, dr.Utiis' tanks and other containers;
(c) Offsite tracking of industrial or waste mate'ri'as or sediment where vehicles enter or exit
the site;
(d) Tracking or blowing of raw, final,or waste materials from areas of no exposure to
exposed areas;
(e) Evidence of, or the potential for, poll rants entering the drainage system; and
(f) Evidence of pollutants discharging to surface waters at all facility outfall(s), and the
condition of and'around the outfall, including flow dissipation measures to prevent
scouring.
The permittee must donsider,the results of the past year's visual and analytical monitoring when
planning and conducting.inspections. Stormwater BMPs associated with airport facilities subject
to industrial stormwater$ermitting requirements identified in the SWMP must be observed
during active operation, i.e., during a stormwater runoff event, to ensure that they are functioning
correctly. If discharge locations are inaccessible, nearby downstream locations must be
inspected.
4. When compliance evaluation schedules overlap with routine facility inspections, the annual
compliance evaluation may also be used as one of the routine inspections, as long as all
components of both types of inspections are included.
SECTION E: CORRECTIVE ACTIONS, FOLLOW-UP MONITORING AND REPORTING
1. The permittee must take corrective action whenever:
(a) Routine facility inspections, comprehensive site compliance evaluations, or any other
process, observation or event result in discovery of any deficiency; or
(b) Following a benchmark exceedance, based on the average of 4 quarterl �monitpo�ringevents, thepermittee determines as a result of reviewing the perms ee's e
permittee's SWMP does not meet the requirements of Part II of this permit.
Part 11 Page W of 15

Permit No. NCS000516
The permittee must review their SWMP and modify it as necessary to address the
deficiency(ies). Revisions to the SWMP must be completed within 14 calendar days following
the discovery. When BMPs need to be modified or added, implementation must be completed
before the next anticipated storm event if possible, but no later than 60 days after discovering the
deficiency(ies), or as otherwise provided or approved by the Division. The amount of time taken
to modify a BMP or implement additional BMPs must be documented.
3. Any corrective actions taken as a result of inspections must be documented and retained for the
3-year period following permit expiration or termination.
4. if at any time monitoring results indicate that the permittee's discharge exceeds a specific
wasteload allocation, or the permittee becomes aware that a discharge causes or contributes to an
exceedance of a water quality standard, the permittee must take immediate steps to eliminate the
exceedances. Within 30 calendar days of implementing the relevant corrective action(s) (or
during the next qualifying runoff event, should none occurowithin 30 calendar days) the permittee
x: �Y
must undertake additional monitoring to verify that the;modified BMPs are effectively protecting
water quality. The permittee need only conduct,follow=up monitoring for pollutant(&) with prior
exceedances unless the permittee has reason to,believe thafth,6 modifications may have reduced
j'Oqp
pollutant prevention or removal capacity for other,pollutants of concern. If the follow-up
monitoring value does not exceed the effluen411&tatton or other relevant standard, the permittee
must submit the follow-up monitoring datartoE,the Division no later than 30 days after the
permittee receives the lab results. In thiseVno?additional follow-up monitoring is required.
Should the follow-up monitoring i�Idicate that�Iihe waste load allocation, water quality standard or
other relevant standard is,still being exceeded, the permittee must submit an Exceedance Report
no later than 30 days afterithe�permitte�e received the lab results. The report must include the
permit identification number` ,Tacility name, address and location; receiving water; monitoring
data from this and the precede g,monitoring event(s); an explanation of the situation; what was
done and intend to do (should` oriective actions not yet be complete) to further reduce pollutants
in the discharge; an4an appropriate contact name and phone number. The permittee must
continue to conductfo.11ow up monitoring at an appropriate frequency, but no less often than
quarterly, until thel iscl arge no longer exceeds the standard, unless the requirement for
additional follow-up monitoring is waived by the Division.
6. Failure to undertake the necessary corrective actions within the stipulated time frames constitutes
a violation of this permit. The underlying cause of the inadequacy or discharge standard
exceedance, e.g., failure to properly implement the SWMP, may also constitute an independent
violation of this permit. Failure to complete follow-up monitoring and reporting within the
stipulated time frames constitutes a violation of this permit.
Part II Page 15 of 15

Permit No. NCS000516
PART III PROGRAM ASSESSMENT
Implementation of the SWMP will include documentation of all program components that are
being undertaken including, but not limited to, inspections, maintenance activities, educational
programs, implementation of BMPs, enforcement actions, and other stormwater activities. If
monitoring and sampling are being performed documentation of results shall be included.
Documentation will be kept'on-file by the permittee for a period of five years and made available
to the Director or his authorized representative immediately upon request.
2. The permittee's SWMP will be reviewed and updated as necessary whenever there is a change in
design, construction, operation, or maintenance which has a significant impact on the discharge,
or potential for discharge, of pollutants to surface waters, routine inspection or compliance
evaluation determines deficiencies in BMPs, an inspection by a local, State, or Federal official
determines that modifications to the Plan are necessary„lor there is a spill, leak or other release;
or any time there is an unauthorized discharge.
3. All aspects of permittee's SWMP shall befreviewedandsupdafed on an annual basip The annual
update shall include an updated list of significant spy siorr ca s o or t e previous
three years, or the notation that no spills haverccurred. The annual update shall include re-
certification that the stormwater outfaIls,have been evaluated for the presence of non-stormwater
discharges. Plan modifications must be made within 30 calendar days after discovery,
observation or event requiring a modificatioo thplementation of new or modified BMPs must be
initiated before the next storm event fopossi ble, but no later than 60 days after discovery, or as
otherwise provided or approver by th'e.Div`ision. The amount of time taken to modify a BMP or
I i € ,aE V
implement additional,�BMPs"=must be documented. If the Plan modification is the result of a
release or unauthorizeij;'discharge ,the permittee must document a description of the release, the
date of the release; th6dirdumstances leading to the release and actions taken in response to the
release; and measures to prevent the recurrence of such releases. Such documentation shall be
kept on -site fora period off ve years and made available to the Director or his authorized
representative imr, mediately upon request.
The Director may notify the permittee when the SWMP does not meet one or more of the
requirements of the permit. Within 30 days of such notice, the permittee will submit a plan and
time schedule to the Director for modifying the SWMP to meet the requirements. The Director
may approve the corrective action plan, approve a plan with modifications, or reject the proposed
plan. The permittee will provide certification in writing (in accordance with Part IV) to the
Director that the changes have been made. Nothing in this paragraph shall be construed to limit
the Director's ability to conduct enforcement actions for violations of this permit.
5. The Division may request additional reporting information as necessary to assess the progress
and results of the permittee's SWMP .
6. The permittee must retain a copy of the current Plan SWMP at the facility, and it must be

Ron,
The Washington RO and Central Office staff met on June 8, 2010 to review the draft permit for NCGTP. I'm forwarding
them a copy of the latest revisions. They may have additional comments. The RO would like to inspect the facility
before they finalize their comments.
Per the WaRO comments and concerns, I added....
Under Part I page 1 of 3, paragraph 4, "If a tenant obtains authorization under this permit and develops a Plan for
discharges from the commercial tenant's own areas of the airport, that Plan must be coordinated and integrated
with the Plan for the entire airport. The Director may require a tenant to apply for and obtain an individual
permit or an alternative General Permit for industrial activities outside the scope of this permit per Part I -
Permit Coverage, paragraph 1 above." Note: the permit did not appear to address WARO concerns about what
the tenants responsibilities with respect to the SWPPP or what would happen if a tenant conducts an industrial
activity that was not covered by the permit (e.g., a tenant/company decides to manufacture "Wipple Dust" at
GTP).
Under Part II Section B Stormwater Management Program, (2) Minimum Control Measures, (f)(ii) Pollution
Prevention and Good Housekeeping, for NCGTP Operations, 41h sentence. I added, "The program shall specify
the frequency of inspections, operation and maintenance..." Note: minor change to clarify that stormwater
BMPs need to be an "Operation and Maintenance Program" that includes proper operation (e.g., regular
inspections and on -going maintenance) .... not simply "maintenance. "
Under Part II Section B Stormwater Management Program, (2) Minimum Control Measures, (f)(ii) Pollution
Prevention and Good Housekeeping, for NCGTP Operations, I added, "NCGTP must identify and map all
structural stormwater BMPs. The map must identify the stormwater outfalls corresponding to each of the BMP as well as
the receiving waters to which these BMPs discharge. The map must be maintained and updated regularly and be available
for review by the permitting authority. NCGTP shall maintain and implement, assess annually and update as necessary an
O&M program for all structural stormwater BMPs. The O&M program shall specify the frequency of inspections and
routine maintenance requirements. NCGTP shall inspect and maintain all structural stormwater BMPs in accordance with
the schedule developed by NCGTP. NCGTP must document inspections and maintenance of all structural stormwater
BMPs." Note: Prior to issuing any permit, the WaRO and CO agrees that it is essential to inspect each BAP to ensure
that each was installed properly and is being properly maintained. As the permit is written, that information would not
have to provided until a year after the effective date.
NCGTP will need to provide:

A map that identifies all structural stormwater BMPs, the stormwater outfalls corresponding to each of the BMP
as well as the receiving waters to which these BMPs discharge; and
A copy of the O&M program for all structural stormwater BMPs. The O&M program shall specify the frequency
of inspections and routine operation and maintenance requirements.
Requesting "additional information" is appropriate and necessary prior to a site visit and issuing the permit. The map
does not need to be detailed or anything fancy. Similarly, the O&M program does not need to be fully developed but
simply be prepared to provide DWQ an description of any routine operation and maintenance (including schedule). If you
need assistance pulling the O&M program together the State's BMP Manual has a description of routine operation and
maintenance for various BMPs.
The RO will schedule a site visit.

PART II FINAL LIMITATIONS AND CONTROLS FOR PERMITTED DISCHARGES
SECTION A: PROGRAM IMPLEMENTATION
The permittee will implement, manage and oversee all provisions of its SWMP to reduce pollutants
discharged from the separate stormwater sewer system. This includes, but is not limited to, the following
areas:
The permittee will develop and maintain adequate legal mechanisms, such as regulations,
ordinances, policies and/or procedures to implement all provisions of the SWMP. The permittee
will keep the Division advised of the status of development of appropriate ordinances and legal
authorities and will pursue these authorities in accordance with the schedule outlined in the
SWMP.
2. The permittee's SWMP will be implemented and manage such that the discharge of pollutants
from the stormwater sewer system is reduced to;the maximum extent practicable. It is
anticipated that in order to meet this provision implementation of the SWMP will occur with
emphasis given to priority areas and to management measures and programs that are most
effective and efficient at varying stages of theiplan's 11 implementation.
3. The permittee will implement the componentsof the SWMP to prohibit, to the maximum extent
practicable, illicit connections, spills and ill6gal'dumping into the stormwater sewer system.
4. The permittee will maintain adequat fun"' ing;and staffing to implement and manage the
provisions of the SWMP. J �
5. The permittee will implement approppr'iate education, training, outreach, and ublic involvement
programs to support the�Ujectives,of this stormwater discharge permit and the SWMP.
The permittee will,iir►plemenfa program to reduce pollution from construction site runoff as
described in the SWIVIP and'in accordance with this permit.
The permittee will implement a post -construction site runoff control program to regulate new
develo ment and redevelo ment y requiring structural and non-structural best management
practices to protect water quality, to reduce pollutant loading, and to minimize post -development
impacts. This program will include provisions for long-term operation and maintenance of
B M Ps.
The pen-nittee will evaluate operations and develop and implement an appropriate program to
reduce the potential for stormwater pollution.
Proposed permit modifications must be submitted to the Director for approval.
10. Discharges of a hazardous substance or oil in excess of reporting quantities caused by a non-
stormwater discharge (e.g., a spill of oil into a separate storm sewer) are not authorized by this
permit. In the event of a spill, the requirements of Section 311 of the CWA and other applicable
provisions of Sections 301 and 402 of the CWA continue to apply.

11. If the permittee becomes subject to an approved TMDL, and following notice of such by
the Division, the permittee shall implement a TMDL Water Quality Recovery Program.
The following additional requirements apply.
(a) Within two years after receiving the Division's notice that tl),e permittee is subject to a
TMDL, the permittee shall establish a TMDL Water Quality Recovery Program and shall
identify the locations of all currently known storm sewer system outfalls within its
jurisdictional area with the potential of discharging the pollutant(s) of concern: to the
impaired segments, to their tributaries, and to segments and tributaries within the
watershed contributing to the impaired segments. The permittee shall also develop a
schedule to discover and locate all other storm sewer system outfalls within its
jurisdictional area that may be discharging the pollutant(s) of concern: to the impaired
stream segments, to their tributaries, and to segments and tributaries within the
watershed contributing to the impaired segments. 41
(b) Within two years after receiving the Division's notice that the permittee is subject to a
TMDL, the permittee shall develop a monitoring' plan for each pollutant of concern. The
monitoring plan shall include the sampEe.locatiomby verbal description and latitude and
longitude coordinates, sample type, frequency, any seasonal considerations, and a
monitoring implementation schedule ffor each'pollutant of concern. Where appropriate,
the permittee may reduce the moniior ng burden by proposing to monitor outfalls that the
Division would consider substailtially,similar to other outfalls. The permittee may also
propose in -stream monitoring where it would complement the overall monitoring plan.
The monitoring plan shall°be adjusted/as additional outfalls are identified in accordance
with the schedule,required in (a) -above and as accumulating data may suggest.
(c) The permittee shall,include•the location of all currently known stormwater sewer system
outfalls with the potentiaFof discharging the pollutants) of concern, the schedule for
discoveringand locating currently unknown stonnwater sewer system outfalls with the
potential of discharging the pollutant(s) of concern, and the monitoring plan, (all as
required inXa) an&(b) above, and all part of the TMDL Water Quality Recovery
Program) in the first SWMP annual report due no earlier than two years after the
Division's initial notification of the applicability of a TMDL.
(d) The next and each subsequent SWMP annual report shall include an assessment of the
available data for each pollutant of concern, and an assessment of the effectiveness of the
BMPs employed, to determine what, if any, additional BMP measures may be necessary
to return the impaired segments to compliance with state water quality standards. The
permittee shall implement appropriate BMPs to control the pollutant(s) of concern to the
maximum extent practicable. Implementation of the appropriate best management
practices constitutes compliance with the standard of reducing pollutants to the
maximum extent practicable.
(e) Following any review and comment by the Division on the TMDL Water Quality
Recovery Program, the permittee shall incorporate any necessary changes into the
program. The permittee shall incorporate the revised TMDL Water Quality Recovery
Program into the SWMP.
The permittee can identify the impaired stream segments in the stormwater sewer system
jurisdictional area by referencing the 2004 Integrated 305(b) and 303(dd) Report (or current
version), available on the website of the Division of Water Quality Modeling and TMDL Unit.

12 If a wasteload allocation (WLA) has been established that applies to the permittee's discharge,
the permittee must develop and implement all necessary controls to meet that allocation. The
permittee must verify that their discharge complies with the WLA through the appropriate
discharge monitoring. Failure to comply with a relevant WLA is a violation of this permit. If the
permittee has properly complied with the requirements of this permit, and finds that the
applicable TMDL does not specify a wasteload allocation or other requirements either
individually or categorically for the permittee's discharge (including disallowing such
discharge), compliance with this permit will be deemed adequate to meet the requirements of the
TMDL.
If a TMDL has not been established that applies to the permittee's discharge the permittee must
comply with the requirements of this permit and any additional conditions stipulated by the
Division. If the permittee has properly complied with all such requirements then compliance with
this permit will be deemed adequate to meet the requiree its for discharging to an impaired
water.
13. This permit stipulates pollutant benchmark concentrations The'benchmark concentrations do not
4'.. �—e
constitute direct numeric effluent limitations; a benchmark exceedance, therefore, is not a permit
violation. Benchmark monitoring data are primarilyto determine the overall effectiveness of the
SWMP and to assist in knowing when additioal corrective action may be necessary to protect
water quality. If the average of four quarterld yischarge samples exceed a benchmark
concentration the permittee must review their SWMP and BMPs to determine whether any
f .,.f i I
improvement or additional controls,are needed to reduce that pollutant in the stormwater
discharge(s). Failure to,undertakeand doedrrient the review, take the necessary corrective
actions, or follow notification procedures stipulated in this permit are violations of this permit.
SECTION B: STORMWA(¢(/TER-MANAGEMENT PROGRAM
f" V
I . The permittee must iievelop,,i mplement, and enforce a storm water management program
designed to reduce the -discharge of pollutants from the MS4 to the maximum extent practicable
(MEP), to protect watei quality, and to satisfy the appropriate water quality requirements of the
Clean Water Act. The storm water management program should include management practices;
control techniques and system, design, and engineering methods; and such other provisions as the
permitting authority determines appropriate for the control of such pollutants. The storm water
management program must include the following information for each of the six minimum
control measures described in Section B.2 of this permit:
(a) The best management practices (BMPs) that the permittee or another entity will
implement for each of the storm water minimum control measures;
(b) The measurable goals for each of the BMPs including, as appropriate, the months and
years in which the permittee will undertake required actions, including interim
milestones and the frequency of the action; and
(c) The person or persons responsible for implementing or coordinating the BMPs for the
stormwater management program.

2. Minimum Control Measures: The six minimum control measures that must be included in the
stormwater management program are: .
(a) Public Education and Outreach on Storm Water Impacts: The permittee must implement
a public education program, within 12 months of.the permit issue date, to distribute
educational materials to the community, conduct equivalent outreach activities about the
impacts of storm water discharges on water bodies, raise public awareness on the causes
and impacts of stormwater pollution and inform the public on the steps they can take to
reduce pollutants in storm water -runoff.
(b) Public Involvement/Participation: The permittee must at a minimum, provide
opportunities for the public to participate in program development and implementation
and comply with State, Tribal, and local public notice requirements when implementing'
a public involvement/participation program.
(c) Illicit Discharge Detection and Elimination:��
a
0) Develop, implement and enforce a.program to�detect and eliminate illicit
discharges (as defined in 40 CFR`§ I22.26(b)(2)) into the MS4;
(ii) Develop, and maintain a storm sewer, system map, showing the location of all
outfal is and the names•and Ioocation of all waters of the United States that receive
discharges from th se�outf6ll �� �/
(iii) To the extent allbwable under'
State, Tribal or local law, effectively prohibit,
through ordiqance, or other regulatory mechanism, non -storm water discharges
into the storm`se�wer system and implement appropriate enforcement procedures
and actions;
(iv) Develop and implement a plan to detect and address non -storm water discharges,
inclu�ding-illegal dumping, to the system;
(v) Inform public employees, businesses, and the general public of hazards
associated with illegal discharges and improper disposal of waste; and
(vi) Address the following categories of non -storm water discharges or flows (i.e.,
illicit discharges) only if identified as significant contributors of pollutants to the
MS4: water line Bushing, landscape irrigation, diverted stream flows, rising
ground waters, uncontaminated ground water infiltration (as defined at 40 CFR
§35.2005(20)), uncontaminated pumped ground water, discharges from potable
water sources, foundation drains, air conditioning condensation, irrigation water,
springs, water from crawl space pumps, footing drains, lawn watering, individual
residential car washing, flows from riparian habitats and wetlands, deehlorinated
swimming pool discharges, and street wash water (discharges or flows from fire
fighting activities are excluded from the effective prohibition against non -storm
water and need only be addressed where they arc identified as significant sources
of pollutants to waters of the United States).
(vii) The permittee may also develop a list of other similar occasional incidental non -
storm water discharges (e.g. non-commercial or charity car washes, etc.) that will
not be addressed as illicit discharges. These non -storm water discharges must not
Part 11 Page 4 of 14

Permit No. NCS000516
be reasonably expected (based on information available to the permittees) to be
significant sources of pollutants to the Municipal Separate Storm Sewer System,
because ofeither the nature of the discharges or conditions established for
allowing these discharges to the MS4 (e.g., a charity car wash with appropriate
controls on frequency, proximity to sensitive waterbodies, BMPs on the wash
Water, etc.). The permittee must document in the SWMP any local controls or
conditions placed on the discharges. The permittee must include a provision
prohibiting any individual non -storm water discharge that is determined to be
contributing significant amounts of pollutants to the MS4.
(d) Construction Site Storm Water Runoff Control
(i). The permittee relies on the NCDENR Division of Land Resources (DLR)
Erosion and Sediment Control Program to comply with this minimum measure.
n . The NCDENR Division of Land Resb rcesErosion and Sediment Control
Program effective meets the requirements�'of theZonstruction Site Runoff

conirol,,wa [e such as discarded building materials, concrete truck washout,
chemicai's, litter, and sanitary waste at the construction site that may cause
adverse impacts to water quality.
(iv). The permittee must provide and promote a means for the public to notify the
appropriate authorities of observed erosion and sedimentation problems. The
permittee may implement a plan promoting the existence of the NCDENR,
Division of Land Resources "Stop Mud" hotline to meet the requirements of this
paragraph.
(v). The permittee may pursue local government implementation of the Erosion and
Sediment Control Program by requesting a "minor modification" to the permit.

handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs.
The program shall specify the frequency of inspections, maintenance, and
housekeeping activities, as well as facility equipment, facility areas, and facility
systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and regular cleaning schedules of these
areas shall be incorporated into the program. The inspection and any subsequent
maintenance activities performed shall be documented, recording date and time
of inspection, individual(s) making the inspection, and a description of the
facility's stormwater control and systems.
Part If Page 6 of 14

Permit No. NCS000516
Within 24 months of permit issuance describe and assess the potential for the
following activities and facility areas to contribute pollutants to stormwater
discharges: aircraft, runway, ground vehicle and equipment maintenance and
cleaning; aircraft and runway deicing operations (including apron and
centralized aircraft deicing stations, runways, taxiways and ramps). If deicing
chemicals are used, the permittee must maintain a'record of the types (including
the Material Safety Data Sheets [MSDS]) used and the monthly quantities, either
as measured or estimated. This includes all deicing chemicals, not just glycols
and urea (e.g., potassium acetate), because large quantitics of these other
chemicals can still have an adverse impact on receiving waters. Commercial
tenants or other fixed -based operations that conduct deicing operations must
provide the above information to the airport authority for inclusion in the airport
authority's Plan. The pollutant list must include all significant materials,
including any hazardous substances or oil handled, treated, stored, or disposed of
that may he exposed to stormwater. I ,,' .
(iv) Secondary Containment Requirements:',&condafy containment is required for:
bulk storage of liquid materials; storage°in any amount of Section 313 of Title III
of the Superfund Amendments.antd Reauthorization Act (SARA) water priority
chemicals; and storage in anyamount,of hazardous substances, in order to
prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks na d saoredrmaterials and their associated secondary
containment areas shall be�"6iniained. If the secondary containment devices are
connected directly 4o stormwater conveyance systems, the connection shall be
controlled by Anuallyactivaated valves or other similar devices (which shall be
secured cl6sed'with a locking mechanism), and any stormwater that accumulates
in the cotainment-area shall be at a minimum visually observed for color, foam,
outfallFstaining, visible sheens and dry weather flow, prior to release of the
accumulated stor`imwater. Accumulated stormwater shall be released if found to
be uncontaminated by the material stored within the containment area.
(v) Conduct and document regular inspections at industrial activities where
industrial materials or activities are exposed to stormwater, structural stormwater
BMPs, and stormwater conveyance systems. Evaluate the sources, document
deficiencies, plan corrective actions, implement appropriate controls, and
document the accomplishment of corrective actions.
(vi) Describe measures that prevent or minimize contamination of the stormwater
runoff from industrial activities with the potential for generating polluted
stormwater runoff.
(vii) Spill Prevention and Response Plan. The Spill Prevention and Response Plan
(SPRP) shall incorporate an assessment of potential pollutant sources based on a
materials inventory of the facility. Facility personnel (or the team) responsible
for implementing the SPRP shall be identified in a written list incorporated into
the SPRP. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through
spills or exposure of materials associated with the facility operations. The SPRP
must be site stormwater specific. Therefore, an oil Spill Prevention Control and
Countermeasure plan (SPCC) may be a component of the SPRP, but may not be
sufficient to completely address the stormwater aspects of the SPRP. The
Part 11 Page 7 of 14

Permit No. NCS000516�
common elements of the SPCC with the SPRP may be incorporated by reference
into the SPRP. Response procedures must include notification of appropriate
facility personnel, emergency agencies, and regulatory agencies, and procedures
for stopping, containing and cleaning up spills. Employees who may cause,
detect or respond to a spill or leak must be trained in these procedures and have
necessary spill response equipment available. Include contact information for
individuals and agencies that must be notified in the event of a spill in the Plan
and in other locations where it will be readily available.
(viii) Within 24 months of permit issuance, develop training program materials.
Within 36 months of permit issuance conduct initial annual training of GTP staff
specific for pollution prevention and good housekeeping procedures. The
permittee must document all training sessions and the employees who received
the training. All employees who work in areas where industrial materials or
activities are exposed to stormwater, or are'responsible for implementing good
housekeeping activities (e.g., inspectors; maintenance personnel), must
participate in the training in annual training. Training must include such topics -
as spill response, good housekeeping, materiaimanagement practices, inspection
and operation and maintenance. The program must include employee training to
prevent and reduce storm water pollution from activities such as park and open
space maintenance, fleet arid'building maintenance, new construction and land
disturbances, and storrn� aw tosystem maintenance.
(ix) Deicing and Anti -Icing Industrial Control Plan: NCGTP shall develop within 24
months -of permit,issuance armanagement plan to minimize possible glycol and
urea disch arges,from,airport areas with these operations. Plan requirements shall
address:
(A(,_"good
Include"Best Management Practices (BMPs), economically reasonable
and appropriate in light of current industry practices, that are selected,desgned, installed, implemented and maintained in accordance with
engineering practices to eliminate or reduce pollutants in the
permittee's discharge;
(B) Describe and ensure implementation of practices used to eliminate or
reduce pollutants in stormwater discharges;
(C) Evaluate present operating procedures to consider alternative practices
that would reduce the overall amount of deicing/ anti -icing chemical
used and/or lessen the environmental impact of the pollutant source.
(D) Evaluate whether excessive application of deicing chemicals occurs and
adjust as necessary, consistent with considerations of flight safety.
(E) Develop and implement a plan for the minimization of the release of
materials used for de-icing into the stormwater system. This plan shall
address:
• The current use and practices employed at the airport for the control
and minimization of entry of the de-icing materials into the
stormwater system; and
Part I I Page 8 of 14

Permit No. NCS000516
m
• The means that may be practicable for modifying current use and
practices to collect the runoff that occurs during and following the
application of the de-icing materials.
Feasible alternatives to the use of urea and glycol -based deicing
chemicals to reduce the aggregate amount of deicing chemicals used
and/or lessen the environmental impact, consistent with
considerations of flight safety.
Airport authorities must determine annually the usage rate of
deicing/anti-icing chemicals at their facility. The total amount of
deicing/anti-icing chemicals used at an airport facility is the
cumulative amount used by the airport authority and each tenant of
the airport facility. In determining the fluid amounts of deicing/anti-
icing chemicals used,at a facility, operators should use the pre -
dilution volume. //"' `` \
(vi) Prepare estimates of annual pollutant loadings discharged to storm sewer
systems or surface waters resulting from discharges of spent deicing/anti-icing
chemicals from the facilityThe loading estimates shall reflect the amounts of
deicing/anti-icing chemicals`discliarged to separate storm sewer systems or
surface waters. /I /, )V_�"
SECTION C: MONITORINdREQUIREMENTS

must document the date and findings of their review. If the permittee determines that the
SWMP satisfies the requirements of this permit, the permittee must document the
justification for this determination. If the permittee determines that the SWMP does not
satisfy the requirements of Part I1 the permittee must initiate corrective action.
(f) The permittee may exercise a waiver of the benchmark monitoring requirements at a
facility that is inactive and unstaffed, as long as there are no industrial materials or
activities exposed to stormwater. If the permittee exercises this waiver, the permittee
must maintain a certification with the SWMP stating that the site is inactive and
unstaffed, and that there are no industrial materials or activities exposed to stormwater.
The permittee must sign and certify the waiver.
(g) Where two or more outfalls discharge substantially identical effluents, based on
similarities of the industrial activities, significant materials, size of drainage areas, and
stormwater management practices occurring within,the drainage areas of the outfalls, the
permittee may conduct visual monitoring of the -discharge at just one of the outfalls and
report that the results also apply to the'substantially identical outfal l(s), provided the
permittee documents in the SWMP tl e,following: Jocations of the outfalls, why the
outfalls are expected to discharge substantially identical effluents, estimates of the size
of the drainage area (in square feet) for each bf the outfalls, and an estimate of the runoff
coefficient of the drainage areas (low under 40"percent; medium: 40 to 65 percent; high:
above 65 percent).
2. Discharges to Impaired Receiving. Monitoring is required for discharges to impaired waters
unless the permittee documents4hat the're'is no exposure of the pollutant of concern to
stormwater at the permittee's site. .M.
(a) . The permittee List submit results from all monitoring to the Division. Discharge
Monitoring Reports sliall'be delivered to the Division no later than 30 days from the date
the facilityTeceives the sampling results from the laboratory.
(b) For discharges -that are conveyed directly or indirectly to impaired waters, monitoring for
the pollutant of concern must be conducted at a minimum of once each permit year
throughout the term of the permit. This monitoring requirement is waived after one year
if the pollutant of concern is not detected in the permittee's stormwater discharge.
(c) For discharges that are conveyed directly or indirectly to waters for which EPA has
approved or established a TMDL with a wasteload allocation applicable to the
permittee's discharge (either specifically or categorically), monitoring for the wasteload
allocation pollutant of concern must be conducted, consistent with any instructions in
TMDL documentation. If the TMDL documentation does not specify monitoring
requirements, monitoring for the pollutant of concern must be conducted at a minimum
of once each permit year throughout the teen of the permit, unless this permit already
assigns the permittee's discharge a benchmark for the pollutant of concern, in which case
the permittee must follow the benchmark monitoring schedule. The monitoring year
begins on the day the permittee's discharge is authorized. This monitoring must be
conducted in addition to all other monitoring requirements prescribed in this permit.
Monitoring of a pollutant of concern for which the discharge has been assigned a
wasteload allocation cannot be waived unless the WLA is specified only in terms of
BMPs, in which case the monitoring requirement is waived after one year if the pollutant
Part II Page 10 of 14

Permit No. NCS000516
of concern is not detected in the stormwater discharge and the permittee documents that
the permittee has adopted the required BMPs.
Monitoring Instructions
(a) The permittee must sample in accordance with the following provisions:
Take a minimum of one grab sample from a discharge resulting from a storm
event with at least 0.1 inch of precipitation (defined as a -measurable event),
provided the interval since the preceding measurable storm is at least 72 hours.
The 72-hour storm interval is waived when the preceding measurable storm did
not yield a measurable discharge, or if you are able to document that less than a
72-hour interval is representative for local storm events during the sampling
period.
ii. Take the grab sample during the.first'30 minutes of the discharge. If it is not
•> N.....�
possible to take the sample dining the -first 30 minutes, sample during the first
hour of discharge and describe why a grab sample during -the first 30 mmutes
was not possible. Submit this�information on or with the Discharge Monitoring
Report. If the sampled discharbe'coE mingles with discharges not authorized
under this permit prior to, reaching the receiving water body, attempt to sample
the stormwater discharge before it -mixes with other waste streams.
iii. Sample collection rese"r'vaatonf and analysis must be conducted according to test
procedures approved under,40 CFR Part 136.
p
(b) Along with the results of Ehe,monitoring, provide the date and duration (in hours) of the
storm event(s)�sampled, rainfall measurements or estimates (in inches) of the storm event
that generated the sampled runoff, the duration between the storm event samples and the
end of the previous measurable (greater than 0.1 inch rainfall) storm event, and an
estimate oftle,total°volume (in gallons) of the discharge samples.
(c) When adverse weather conditions -prevent the collection of samples according to the
relevant monitoring schedule, take a substitute sample during the next qualifying storm
event. Adverse conditions (i.e., those that are dangerous or create inaccessibility for
personnel) may include events such as local flooding, high winds, electrical storms, or
situations that otherwise make sampling illogical, such as drought or extended frozen
conditions.
(d) The Division may provide written notice requiring additional discharge monitoring
briefly stating the reasons for the monitoring, locations and parameters to be monitored,
frequency and period of monitoring, sample types, and reporting requirements.
4. Qualitative Monitoring Requirements
(a) The permittee must perform and document a quarterly visual examination of a
stormwater discharge associated with industrial activity from each outfall, except as
provided for in Part I1.C.3(c), Adverse Weather Conditions. The visual examination must
be made during daylight hours. If no storm event resulted in runoff during daylight hours
from the facility during a monitoring quarter, the permittee is excused from the visual
Part I I Page I I of 14

i
Permit No. NCS000516
monitoring requirement for that quarter, provided the permittee documents that no runoff
occurred.
(b) Qualitative monitoring requires a visual inspection of each stormwater outfall regardless
of representative outfall status. Qualitative monitoring is for the purpose of evaluating
the effectiveness of the SWMP and assessing new sources of stormwater pollution. No
analytical tests are required. Qualitative monitoring shall be performed at each
stormwater discharge outfall regardless of representative outfall status. Visual
examinations must be made on samples collected within the first N minutes (or as soon
-thereafter as practical, but not to exceed 1 hour) of when the runoff or snowmelt begins
discharging form the outfall. All samples must be collected from a storm event discharge
that is greater,than 0,1 inch in magnitude and that occurs at least 72 hours from the
previously measurable (greater than 0.1 inch rainfall) storm event. The 72-hour storm
interval is waived when the preceding measurable storm did not yield a measurable
discharge, or if it can be documented that less.than'a 72-hour interval is representative
for local storm events during the sampling period. The examination must document
observations of color, odor; clarity, floating, soltds,bsettled'solids, suspended solids,
foam, oil sheen, and other obvious indicator's of -stogy mwater pollution.
(c) In the event an atypical condition is nosed at a.stormwater discharge outfall, the
permittee shall document the suspected,cause of the condition and any actions taken in
response to the discovery. This'd umentation will be maintained with the SWMP.
(d) Visual examination reports must be maintained onsite with the SWMP. The report must
include the examination" date and time, inspection personnel, nature of the discharge (i.e.,
runoff or snowmelt), `visual quality of the stormwater discharge (including observations
of color, odor, clarity,,noating solids, settled solids, suspended solids, foam, oil sheen,
and other obvious indicators of stormwater pollution), and probable sources of any
observed stormwater Contamination.
(e) All qualitative -monitoring will be performed four times per year, once in the periods of
January —March;:April — June; July — September;.and October — December. In the
January — March period the qualitative monitoring shall be performed when de-
icing/anti-icing is occurring, when possible.,
(f) If the permittee's qualitative monitoring indicates either that existing stormwater BMPs
are ineffective, or that significant stormwater contamination is present, the permittee
shall investigate potential causes, evaluate the feasibility of corrective actions, and
implement those corrective actions appropriate.
(g) The permittee may exercise a waiver of the visual monitoring requirements at a facility
that is inactive and unstaffed, as long as there are no industrial materials or activities
exposed to stormwater. If the permittee exercises this waiver, the permittee must
maintain a certification stating that the site is inactive and unstaffed, and that there are no
industrial materials or activities exposed to stormwater. The permittee must sign and
certify the waiver.
Part 11 Page 12 of 14

Permit No. NCS000516
SECTION D: COMPLIANCE EVALUATION OF INDUSTRIAL ACTIVITIES
The permittee must conduct a comprehensive site. compliance evaluation of airport facilities
subject to industrial stormwater permitting requirements at least once a year. Conduct annual site
compliance evaluations during periods of actual deicing operations: If not practicable during
active deicing or the weather is too inclement, conduct annual site compliance evaluations when
deicing operations are likely to occur and the materials and equipment for deicing are in place.
2. inspections must cover all the areas where industrial materials or activities are exposed to
stormwater, along with areas where spills and leaks have occurred in the past 3 years. Inspectors
must examine the following: '
(a) Industrial materials, residue or trash that may have or could come into contact with
stormwater;
(b) Leaks or spills from industrial equipment, drums; tanks and other containers;
(c) Offsite tracking of industrial or waste materials,or "sediment where vehicles enter or exit
the site;
�r
(d) Tracking or blowing of raw, final. or waste materials from areas of no exposure to
exposed areas;
(e) Evidence of, or the potential'for;l pollutants entering the drainage system; and
(f) Evidence of p6llutants`discharging to surface waters at all facility outfall(s), and the
� ro e
condition of and aroundy the,Zfall, including flow dissipation measures to prevent
scouring.i'
The permittee must `donsider ttie results of the past year's visual and analytical monitoring when
planning and conducting -inspections. Stormwater BMPs associated with airport facilities subject
to industrial storm wafer"permitting requirements identified in the SWMP must be observed
during active operation, i.e., during a stormwater runoff event, to ensure that they are functioning
correctly. If discharge locations are inaccessible, nearby downstream locations must be
inspected.
4. When compliance evaluation schedules overlap with routine facility inspections, the annual
compliance evaluation may also be used as one of the routine inspections, as long as all
components of both types of inspections are included.
SECTION E: CORRECTIVE ACTIONS, FOLLOW-UP MONITORING AND REPORTING
The permittee must take corrective action whenever:
(a) Routine facility inspections, comprehensive site compliance evaluations, or any other
process, observation or event result in discovery of any deficiency; or
rj (b) following a benchmark exceedance, based on the average of 4 quarterly monitoring
f events, the vermittee determine as a result of reviewing the ermittee s SWMP that the
permittee's SWMP does not meet the requirements o Part II of this permit.
Part 11 Page 13 of 14

Permit No. NCS000516�
2. The permittee must review their SWMP and modify it as necessary to address the
deficiency(ies). Revisions to the SWMP must be completed within 14 calendar days following
the discovery. When BMPs need to be modified or added, implementation must be completed
before the next anticipated storm event if possible, but no later than 60 days after discovering the
deficiency(ies), or as otherwise provided or approved by the Division. The amount of time taken
to modify a BMP or implement additional BMPs must be documented.
3. Any corrective actions taken as a result of inspections must be documented and retained for the
3-year period following permit expiration or termination.
4. If at any time monitoring results indicate that the permittee's dischar a exceeds a specific
n w`stelo� ll cation or the permittee becomes aware that a discharge causes or contributes to an
l exceedance of water _uality standard, the permittee must take immediate steps to eliminate the
e excee anc es. Within 30 calendar days of implemen mg ze relevant corrective action(s) (or
during the next qualifying runoff event, shoula none occur within 30 calendar days) the permittee
must undertake additional monitoring to verify that tlierriodified BMPs are effectively protecting
water quality. The permittee need only conduct,follow-up`monito-ring for pollutant(s) with prior
exceedances unless the permittee has reason to believe that thd,modifications may have reduced
pollutant prevention or removal capacity for other pollutants'of concern. If the follow-up
monitoring value does not exceed the effluent�limitation or other relevant standard, the permittee
must submit the follow=up monitoring data'to the Division no later than 30 days after the
permittee receives the lab results. In this -case; no additional follow-up monitoring is required.
e � '// )rl
5. Should the follow-up monitoring in&,ate'thatthe wasteload allocation, water quality standard or
other relevant standard is,still being exceeded, the permittee must submit an Exceedance Report
no later than 30 days after the permittee received the lab results. The report must include the
permit identification numb"er;'facility dame, address and location; receiving water; monitoring
data from this and the preceding monitoring event(s); an explanation of the situation; what was
done and intend to do (should' corrective actions not yet be complete) to further reduce pollutants
in the discharge; anran appropriate contact name and phone number. The permittee must
continue to conduct full '�up monitoring at an appropriate frequency, but no less often than
quarterly, until .the discharge no longer exceeds the standard, unless the requirement for
additional follow-up monitoring is waived by the Division.
Failure to undertake the necessary corrective actions within the stipulated time frames constitutes
a violation of this permit: The underlying cause of the inadequacy or discharge standard
exceedance, e.g., failure to properly implement the SWMP, may also constitute an independent
violation of this permit. Failure to complete follow-up monitoring and reporting within the
stipulated time frames constitutes a violation of this permit.

PART III PROGRAM ASSESSMENT
Implementation of the SWMP will include documentation of all program components that are
being undertaken including, but not limited to, inspections, maintenance activities, educational
programs, implementation of BMPs, enforcement actions, and other stormwater activities. If
monitoring and sampling are being performed documentation of results shall be included.
Documentation will be kept on -file by the permittee for a period of five years and made available
to the Director or his authorized representative immediately upon request.
The permittee's SWMP will be reviewed and updated as necessary whenever there is a change in
design, construction, operation, or maintenance which has a significant impact on the discharge,
or potential for discharge, of pollutants to surface waters, routine inspection or compliance
evaluation determines deficiencies in BMPs, an inspection by a local, State, or Federal official
determines that modifications to the Plan are necessary,,or there is a spill, leak or other release;
or any time there is an unauthorized discharge.
All aspects of permittee's SWMP shall beireview ed'and,updated on an annual basis. -The annual
update shall include an updated list of significant spills orrleaks of pollutants for the previous
three years, or the notation that no spills have occurred. The annual update shall include re-
certification that the stormwater outfalls.have bec evaluated for the presence of non-stormwater
discharges. Plan modifications must be made.,within 30 calendar days after discovery,
observation or event requiring a modification.lmplementation of new or modified BMPs must be
initiated before the next storm event ifipossible, but no later than 60 days after discovery, or as
otherwise provided or approvedrby the,Division. The amount of time taken to modify a BMP or
implement additional„BMP .must be-doc mented. If the Plan modification is the result of a
�- = �;
release or unauthorized discharge] the permittee must document a description of the release, the
date of the release; the circumstances leading to the release and actions taken in response to the
release; and measures to prevent the recurrence of such releases. Such documentation shall be
kept on -site for a period offive years and made available to the Director or his authorized
%.. ed
representative immediately upon request.
The Director may notify the permittee when the SWMP does not meet one or more of the
requirements of the permit. Within 30 days of such notice, the permittee will submit a plan and
time schedule to the Director for modifying the SWMP to meet the requirements. The Director
may approve the corrective action plan, approve a plan with modifications, or reject the proposed
plan. The permittee will provide certification in writing (in accordance with Part IV) to the
Director that the changes have been made. Nothing in this paragraph shall be construed to limit
the Director's ability to conduct enforcement actions for violations of this permit.
5. The Division may request additional reporting information as necessary to assess the progress
and results of the permittee's SWMP.
The permittee must retain a copy of the current Plan SWMP at the facility, and it must be
immediately available at the time of an on -site inspection.

EXECUTIVE SUMMARY
1
Purpose
' This document represents the Comprehensive Stormwater Management Program Report for
part one of a two part application pursuant to the North Carolina Global TransPark Authority
(NCGTP Authority) seeking a National Pollution Discharge Elimination System (NPDES)
' stormwater permit. With receipt of the system -wide NPDES permit, the NCGTP Authority
intends to develop and implement a Stormwater Management Program (SWMP) that will
manage the stormwater discharge from the NCGTP NPDES Permit Area at the North Carolina
' Global TransPark (NCGTP) Site and comply with the reporting requirements of the North
Carolina Division of Water Quality (DWQ). The approach to stormwater management will
' provide for stormwater management on the existing deve1pment with additional controls as
new sites are developed that will allow integration of structural and nonstructural stormwater
controls, provide greater benefits to water quality, reduce threats from avian wildlife populations
' typically associated with aircraft strikes (Canada geese, gulls, etc.), and comply with all
requirements associated with the Neuse River Nutrient Sensitive Waters Management Strategy.
' Background
The Clean Water Act of 1972 established a permitting program for the discharge of pollutants
into waters of the United States from point sources through the NPDES program. The NPDES
' program includes two phases. Phase I of the NPDES permitting program covered Municipal
Separate Storm Sewer Systems (MS4s) designated as "large" or "medium" as defined by their
population, and also construction projects disturbing 5 acres or more. Large MS4s include
' incorporated municipalities or counties with populations of 250,000 or greater. Medium MS48
include those with populations between 100,000 and 249,999. Phase it of the NPDES
Stormwater program was signed into law in December of 1999. This regulation builds upon the
' existing Phase I program in three ways: (1) lowers the acreage threshold for construction
activities from 5 acres down to 1 acre or more of disturbed area; (2) provides a no -exposure
exemption for Phase 1 industrial facilities that have no significant materials stored outdoors; and
' (3) requires small MS4s to be permitted. A small MS4 is a unit of government such as a city,
town, county, association or other public body that owns or operates a stormwater collection
system. The United States Environmental Protection Agency (EPA) represents the federal
' agency responsible for administering the NPDES program. The NPDES permitting process is
designed primarily to protect water quality through identification and control of pollutants from
stormwater runoff and industrial discharges.
' The State of North Carolinah n delegated the author' t administer the
as been authority from the EPA o
' NPDES program, including issuance of NPDES stormwater permits (40 CFR 122.26). In North
Carolina, DWQ is responsible for overseeing the program. For discharges of stormwater runoff
from construction sites involving disturbance of 1 acre or more, an NPDES permit must be
' submitted to DWQ for review and approval prior to construction. This comprehensive NPDES
permit, when issued, will serve to transfer NPDES program oversight for NCGTP site -specific
activities from DWQ to the NCGTP Authority. Subsequently, the NCGTP Authority will provide
' ii

annual reports to DWQ summarizing stormwater and NPDES program activities at NCGTP.
The NCGTP desires to be a part of the NPDES Phase 11 program via the petition option.
Pollution control measures regulated by the NPDES permit process for individual industrial sites
are widely recognized as providing marginal water quality benefits in developing areas (EPA
1992). Evidence indicates that diffuse sources (occurring over a wide area) of water pollution
are also major causes of water quality problems. Runoff from streets, utilities, small
construction sites, illegal dumping, commercial developments (less than 1 acre), and other
auxiliary sources export and accumulate pollutants in streams below the developing watershed.
A growing awareness of the magnitude of these diffuse sources of water pollution in developing
areas has emerged over the last several decades. By providing site -specific stormwater
controls and oversight, the NCGTP Authority will promote control of diffuse sources of pollution
(from areas less than 1 acre) in tandem with control of pollution from major developments
(greater than 1 acre).
This system -wide NPDES permit is intended to cover all NCGTP-related development within the
2313-acre NCGTP NPDES Permit Area, with the potential intent to gradually expand
responsibility as new development occurs. The NCGTP Authority proposes to implement
' stormwater programs and enforce stormwater rules under its permit for NCGTP-related
activities. Therefore, a phased approach for implementation and enforcement is proposed.
tFormat and Objectives for the NPDES Permit Application
This NCGTP application for a comprehensive NPDES Phase 11 permit will be submitted in two
parts, the NPDES Stormwater Permit Application Form (SWU-264) and the Comprehensive
Stormwater Management Program Report (CSMPR). The CSMPR includes all required
information as stated in the NPDES Stormwater Permit Application Form. This document will
' provide the following information:
1. Storm Sewer System Information
t This section summarizes population information and land use. Total Maximum Daily
Load (TMDL) requirements are also discussed in this section.
' 2. Receiving Streams
This section lists the primary receiving streams for the NCGTP site and identifies water
quality issues associated with these streams.
' 3. Existing Water Quality Programs
' This section lists local and state programs already being implemented by the NCGTP
Authority.
4. Permitting Information
' This section provides information on the responsible parties and their responsibilities
toward goals.
' iii

1
5. Co -Permitting Information
' NCGTP is not working with any other MS4s to develop their Phase II stormwater
program and, therefore, this section is not applicable.
' 6. Reliance on other government entities to satisfy permit obligations
This section provides a listing of government entities responsible for satisfying any part
' of the NCGTP permit obligation.
7. Stormwater Management Program Plan
This section defines the plan designed to reduce discharge or pollutants, protect water
quality, and satisfy requirements of the Clean Water Act. The six major programs
addressed in detail are as follows:
' 1. Public Education and Outreach
2. Public Involvement and Participation
' 3. Illicit Discharge Detection and Elimination
4. Construction Site Stormwater Runoff Control
5. Post Construction Stormwater Management in New Development and Redevelopment
' 6. Pollution Prevention ! Good Housekeeping for Municipal Operations

COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT
This document represents the Comprehensive Stormwater Management Program Report for
one part of a two part, application pursuant to the North Carolina Global TransPark Authority
(NCGTP Authority) assuming permitting responsibility for system -wide, stormwater-related
issues falling under the scope of the National Pollution Discharge Elimination System (NPDES)
stormwater discharge permitting requirements. With receipt of the system -wide NPDES permit,
the NCGTP Authority intends to assume oversight responsibility for stormwater discharge in the
Cargo Airport Area at the North Carolina Global TransPark (NCGTP) Site and reporting as
required to the North Carolina Division of Water Quality (DWQ). The approach to stormwater
management will provide for management on the existing development with additional controls
as new sites are developed that will allow integration of structural and nonstructural stormwater
controls, provide greater benefits to water quality, reduce threats from avian wildlife populations
typically associated with aircraft strikes (Canada geese, gulls, etc.), and comply with all
requirements associated with the Neuse River Nutrient Sensitive Waters Management
Strategy...
1.0 STORM SEWER INFORMATION
1.1 Population Served
A census population served in the NCGTP NPDES Permit Area is not applicable in this
situation. Currently, there are approximately 2,700 employees from various companies in the
GTP Initial Development Area, of those employees, approximately 400 are tenant employees at
the GTP. These numbers do not include the approximate 800 temporary construction jobs that
have been created since the Spirit AeroSystems' (Spirit) project at the GTP began in September
2008. These temporary jobs will last at least until the spring 2010. Spirit will create a minimum
of 1,031 high -paying jobs over a six -year period, beginning next year.
1.2 Growth Rate
' The growth rate of the NCGTP NPDES Permit Area is not applicable in this situation. The
NCGTP NPDES Permit Area is defined by the existing and recently expanded facilities, as well
as the proposed development within the immediate vicinity of the airport and NCGTP owned
' land. Over the years, the GTP tenant based has grown to approximately 400 employees. GTP
tenants include Mountain Air Cargo, Segrave Aviation/Pegasus Elite, Henley Aviation, New
Breed, Spatial Integrated Systems (SIS), Commerce Overseas 9COC), Longistics, MJE
' Telestructure, NC Emergency Management — Eastern Branch, NC Forest Service, NC Highway
Patrol, and NC's Eastern Region. The NCGTP facilities are 90% leased at this time.
' 1.3 Jurisdictional and MS4 Service Areas
The NCGTP Site is located in Lenoir County just south of the border between Lenoir and
' Greene Counties and north of the City of Kinston, North Carolina (Figure 1). The NCGTP
NPDES Permit Area includes 2313-acres (3.614 square miles (mil) as shown in Figures 1 and
2. There are also two larger boundaries not being considered for a NPDES permit at this time,
1

1
but are planned as potential expansion boundaries of the NCGTP site. These areas are the
' 5775-acre (9.023 mil) Section 404 Permit Area and the 15,726-acre (24.572 mil) Ultimate
Buildout Boundary (Figure 1).

1.4 MS4 Conveyance System
The major drainage system associated with the NCGTP Site is the Neuse River Drainage Basin
which serves as the ultimate receiving waters for stormwater runoff in the area. The portion of
the Neuse River receiving runoff from the NCGTP site is approximately 6.6 miles to the east of
the NCGTP Site in eastern Lenoir County. Local stormwater drainage within NCGTP
boundaries occurs within four primary basins and their tributaries: 1) Stonyton Creek (SC), 2)
Briery Run (BR), 3) Wheat Swamp (WS), and 4) Gum Swamp (GS). Table 1 and Figure 3
depict the major drainage basins, designated watersheds within each drainage basin, and the
associated acreage by land use contributing stormwater to each stream system. The Ultimate
NCGTP Site (Site) has been divided into 39 sub -basins for planning purposes (Figure 3).
Stonyton Creek represents the primary receptor of runoff associated with initial development in
the Air Cargo Complex and Section 404 Permit Area. The stream originates approximately
3000 feet west of the existing airport facility. The drainage area of Stonyton Creek
encompasses approximately 5998 acres or 38 percent of the total 15,726-acre ultimate NCGTP
Site (Table 1, Figure 3).
Briery Run represents the southern boundary of the Site and flows east approximately 5 miles to
its confluence with Stonyton Creek. The drainage area of Briery Run includes approximately
3983 acres or 25 percent of the Site. Wheat Swamp forms the northern boundary of the Site
and discharges into Contentnea Creek. The drainage area of Wheat Swamp includes
approximately 5031 acres or 32 percent of the land area. Gum Swamp receives minimal
drainage from approximately 714 acres (5 percent of the land area) along the western periphery
of the Site.
The general transport of stormwater runoff from the site is directly from sheet flow to a series of
drainage ditches leading to Stonyton Creek, Briery Run, and Wheat Swamp (Figure 3). These
ditches are maintained through periodic inspection and removal of debris and/or sediment
blocking the path of the water.
1.5 Land Use Composition Estimates
Land use within the 2313-acre NCGTP NPDES Permit Area can be broken into roughly four
types: agricultural, industrial/infrastructural, forested, and residential. About 700 acres are used
for agricultural purposes comprising approximately 32 percent of the overall land use. Forested
land covers the largest percentage of the area with about 792 acres, or 36 percent. About 29
percent of land use is infrastructure and industry covering nearly 638 acres. The remaining 3
percent of the land is residential area, which covers about 61 acres (Table 1 and Figure 4).
1.6 Estimate Methodology
Land use areas were determined using property boundaries and current land use within the
2313-acre NCGTP NPDES Permit Area. Areas of a common land use type were summed to
provide the reported results.

1.7 TMDL Identification
Communities within the Neuse River basin are required to control the amount of nitrogen inputs
into streams under the Neuse River Nutrient Sensitive Waters Management Strategy (DWQ,
1998; NCAC, 2004). The limit for annual loading from new development is currently 70 percent
of the average nitrogen load contributed by the 1995 land uses of the non -urban areas of the
Neuse River Basin, or 3.6 pounds/acre.
Analysis of baseline water -quality and discharge data for seven sub -watersheds within NCGTP
reveals that average annual flow rates within separate reaches ranged from 0.74 to 6.06 cubic
feet per second (cfs) for the Stonyton Creek drainage band from 1.66 to 2.35 cfs for the Briery
Run drainage. Based on these discharge values and the corresponding measured nutrient
concentrations at each station, the estimated average annual nitrogen loading for the various
sub -watersheds within NCGTP range between 4,387 to 25,322 pounds per year (lb/yr),
respectively. Average, annual TN and TP loading for the Briery Run at the most downstream
monitoring location (BR 06 and BR 08 combined) was estimated to be 14.0 Iblyr and 965.6 Iblyr
respectively. Average, annual TN and TP loading for Stonyton Creek at the most downstream
monitoring location (SC3-11) was estimated to be 22,624 Iblyr and 2,780 Iblyr, respectively.
Flow regimes within the two subject drainages were notably different: Stonyton Creek has a
restricted flow regime caused by numerous beaver impoundments, while the Briery Run
drainage is relatively free flowing. Consequently, flow rates of Stonyton Creek are nearly 40-
percent less than that of similar -sized sub -watersheds within the Briery Run drainage. In fact,
while watershed size increases over 20-percent in the furthest downstream reach of Stonyton
Creek (between NC58 and E. N. Dickerson Road), total nitrogen loading unexpectedly
decreases 11 percent and total phosphorus decreases 4 percent. This observed reduction of
total nitrogen and phosphorus loading in Stonyton Creek is presumably due to predominant low
flow conditions, which in turn heighten sedimentation, dentrification, and removal of adhered
phosphorus compounds.

' jetport maintenance personnel servicing commercial aircraft, tenants owning and servicing
private aircraft, tenants storing materials considered as watershed pollutants such as deicing
' chemicals and petroleum products, and ground disturbing activities associated with both
existing and new development.

7.1.4 Outreach Program
Tenants and the general public can most easily be reached by providing information through
newsletters and on the NCGTP website. Roadside pull -over locations provide an easily
accessible form of education for the general public, and their creation is an opportunity for public
involvement. The displays at the airport terminal will provide stewardship awareness to patrons
and visitors to the airport terminal. Training and workshops planned at the Global TransPark
Center can be focused toward providing tenants and local business owners with a better
understanding of the overall movement of stormwater, and with ways that the quality of
stormwater can be protected.
7.1.5 BMP Selection Process
The selected activities shown in Table 3 were chosen in part because some can work in
cooperation with the NCGTP Mitigation Plan educational requirements. Activities such as the
roadside pull -over and terminal exhibits will be developed for both environmental impact and
stormwater impact, showing the importance of both and how the two are interconnected.
Newsletter articles and website information are potential ways to reach an area -wide audience.
7.1.6 Evaluation
Evaluation of success for the listed activities in Table 3 can be assessed by determining if target
goals for that BMP have been met. For the website, a target visitor number can be used as the
success criteria. The number of newsletters distributed each year is another measurable goal.
An ongoing roadside pull -over will be used and can be evaluated through visitor counts. The
Environmental Compliance Officer will be responsible for keeping track of the activities and
determining whether or not target goals have been met.
7.2 Public Involvement and Participation
This section outlines how the NCGTP Authority plans to involve the public in their stormwater
plan, helping to maintain and improve the stormwater runoff quality.

1 7.2.2 Target Audience
u
The target audience for public involvement and participation is similar to the audience proposed
for education and outreach. It is the aim of the NCGTP Authority to involve the tenants, local
industries and businesses as well as the general public in the implementation of a stormwater
plan created to protect water quality. Children are targeted in order to stress the importance of
protecting the environment at a young age.
7.2.3 Participation Program
Citizen participation includes the invitation to actively participate in stormwater planning meeting
and seminars. The participation of schools and organizations such as the Boy/Girl Scouts in
clean water and conservation programs creates an "ownership" in the programs that might well
carry over to adults in their lives.
7.2.4 BMP Selection Process
The selected activities were chosen for several reasons. The outdoor exhibits are part of the
NCGTP Mitigation Plan educational requirements. The student volunteer program to clean
streams is an activity that can also be used in conjunction with the detection of illicit discharges
(Section 7.3).
7.2.5 Evaluation
Evaluation of the public participation and involvement measure can be done by setting a "turn-
out" goal for each activity, and determining whether or not that goal was met.
7.3 Illicit Discharge Detection and Elimination
This section outlines all the BMP steps NCGTP Authority will take in order to detect and
eliminate illicit discharges to receiving waters from the Cargo Airport site.

7.3.2 Storm Sewer System Map JLVaa
A map of the existing stormwater flows, including outfall locations into receiving waters, will be
developed as part of the Stormwater Infrastructure Inventory section of the NCGTP Stormwater
Master Plan. This map will be updated continually by the Environmental Compliance Officer as
new development occurs and will be used to guide development planning in the watersheds.
This map will also provide the tools to quantify impervious surface areas and discharges, route
stormwater flows, track water quality data, and catalog collected information concerning
industrial users within the stormwater conveyance infrastructure. Figure 6 shows the existing
surface drainage characteristics of the NCGTP Site.

7.3.3 Regulatory Mechanism
In order to effectively prohibit illicit discharges within the NCGTP site, the NCGTP Authority will
develop and adopt an Illicit Discharge Ordinance explaining responsibility, monitoring, use of
both structural and non-structural best management practices, notification requirements, and
enforcement. This ordinance is to be established within the first year of the NPDES permit.
7.3.4 Enforcement
Enforcement of the Illicit Discharge Ordinance may be done by imposing fines on a per -day
basis for violations. The developed ordinance will explain the enforcement policy in greater
detail.
7.3.5 Detection and Elimination
In order to effectively detect and eliminate illicit discharges, several activities must take place: 1)
identify problem area, 2) determine the source of the problem and, 3) correct the illicit
connection. The Environmental Compliance Officer will determine priority areas to be screened
on a regular basis where illicit connections are more likely to be a problem. Such areas include
sites where sanitary sewer connections are older and sites where hazardous materials have the
potential to be disturbed. Methods for detection of problem areas can include, but are not
limited to, public complaints, dry weather water sampling, and thermal photography.
' Several methods may be used to locate the source of the illicit discharge. Dye tests and smoke
tests, routine inspection, and tracing the problem upstream are all valid methods of determining
the origin of an illicit discharge.
1 Once the source of an illicit discharge is determined, it must be removed or repaired. The
Environmental Compliance Officer must contact the party responsible for the discharge and
' inform the responsible party that the discharge must be corrected. Fines may be imposed on a
per -day basis in order to ensure the problem is corrected in a timely manner.
1
7.3.6 Non-Stormwater Discharges — Illicit
Certain non-stormwater discharges are considered illicit and are to be controlled to prevent their
entry into the stormwater system. However, illicit discharges are not limited to these certain
discharges and include any substance other than stormwater not listed in Section 7.3.7 that may
pose an environmental or health threat. Non-stormwater discharges that are always considered
illicit are the following:
• oil, anti -freeze, paint, cleaning products,
• animal wastes,
• garbage,
• discharge from commercial car washes,
• industrial discharges,
• contaminated air conditioning condensate, and
• contaminated water from foundation or footing drains.
17

1
1
1
7.3.7 Non-Stormwater Discharges — non -illicit
The following non-stormwater discharges are permitted to enter the stormwater system so long
as they do not significantly impact water quality:
• uncontaminated condensate from air conditioning;
• discharges associated with emergency removal and treatment activities, for
hazardous materials, authorized by the federal, State or local government on -scene
coordinator;
• collected infiltrated water from foundation or footing drains;
• irrigation water;
• fire fighting discharge;
• discharge from pumping or draining of natural watercourses or water bodies;
+ flushing and cleaning of stormwater conveyances with unmodified potable water;
+ wash water associated with the cleaning of the exterior of buildings, provided this
water does not pose an environmental or health threat; and
• other stormwater discharged for which a valid NPDES permit has been approved
and issued by DWQ, and the discharge is authorized by the NCGTP Authority.
' 7.3.8 Outreach
Outreach to tenants, local businesses, and the general public will be done as described in
' sections 7.1 and 7.2. One article per year in the newsletter will be based upon educating the
reader in proper handling of waste, identifying illicit discharges within the NPDES permit area,
and other relevant topics. The website and displays within the ETC and main airport terminal
' will also periodically show topics presenting the effects of illicit discharges to the receiving
waters. These activities will be a sign to all NCGTP employees, tenants, local businesses, and
the general public of the importance NCGTP places on the prevention of'stormwater pollution.
I
The public will also be informed of the effects of NCGTP's good housekeeping efforts as they
relate to stormwater.
t7.3.9 BMP Selection Process
These best management practices outlined in Table 5 were chosen for their positive controllable
measures to prevent potential pollutant discharges. The proposed training, newsletter articles,
and hotline provide opportunities to educate and remind NCGTP employees and tenants
concerning illicit discharge elimination goals and to provide an efficient notification process to
' minimize harm should an inadvertent discharge occur.
7.3.10 Evaluation
' The detection and elimination of illicit discharges will be evaluated over time by observing the
number of illicit discharges detected and the number of these discharges that are remediated.
There should be an observed decrease in the number of illicit non-stormwater discharges into
' the receiving waters. Water quality monitoring will be used as an evaluation method to
document improving stormwater quality.

7.4 Construction Site Stormwater Runoff Control
The NCGTP Authority will rely upon the NCDENR - Division of Land Resources (DLR)
requirements for sediment and erosion control from construction sites. The Environmental
Compliance Officer in concert with the DLR regional office will monitor compliance with
approved sediment and erosion control plans. r ,rjwA� f r
7.6 Post -Construction Stormwater Management VIP,' `"' V's A' ��fAi&WN"'A.- T
A program for managing post -construction stormwater discharges will be developed as part of
the current Land Development Guidelines. In order to enforce this program, an ordinance will
be developed addressing stormwater runoff from new construction. sous ? c,,Pr 7
This ordinance will address silt leaving the site during construction, stormwater detention
basins, and prohibition of construction staging areas in wetlands or other sensitive areas.

7.6.2 Affected Operations
G lNr.4�
General maintenance operations that are an extension of the BMP's included in Table 6 include
general road and parking lot cleaning and maintenance; mowing and landscaping; control of
washing, fueling and de-icing locations for airplanes; and ,the se/storage/maintenance of any
chemicals or fertilizers used for these purposes.or~`
7.6.3 Training
All NCGTP operations and maintenance employees will be required to complete a stormwater
awareness training program as part of an already existing safety training program at the start of
their employment. This training activity will educate the employees on the importance of
stormwater quality and on the aspects of their jobs that may have some relation to stormwater.
' 20

7.6.4 Maintenance and Inspections
Maintenance personnel will be required to inspect stormwater inlets and outfalls for any
noticeable impairments, leaks, or discharges other than stormwater on a regular basis as part of
general airport maintenance operations. The drains in the maintenance shop will be checked
for outlet location with special attention given to is ou all. ?
7.6.5 Vehicular Operations
Pollutants from vehicular operations will be controlled in several ways. All NCGTP operational
vehicles are kept in one of three areas: the main terminal, the Airport Rescue and Fire Fighting
facility, and the maintenance shop, with the majority of the vehicles at the maintenance shop.
All NCGTP vehicles go the maintenance shop for service and to the maintenance wash bay
area to be cleaned. NCGTP tenants will be required to develop a dedicated vehicle
maintenance area unless their vehicles are maintained and cleaned off -site.
7.6.6 Waste Disposal
All vehicle service takes place in the maintenance area. The service area is cleaned on a daily,
weekly, and monthly basis as needed with approved clean up "pigs" to recover any
hydrocarbon, glycol, etc. Oil dry and other recovery products are also used for cleaning the
maintenance area. All waste materials are collected in containers approved by the Lenoir
County Fire Marshall and are transported by NCGTP personnel to the Lenoir County Landfill for
proper disposal. Lawn clippings are currently disposed of in place. If any NCGTP tenant
maintains a separate maintenance area, they will be required to develop a waste disposal
program similar to that of the GTP and the area will be routinely inspected for compliance.
7.6.7 Flood Management Projects
NCGTP does not presently have any known flood management projects in place.
7.6.8 Existing Ordinances
The NCGTP Board of Directors will adopt an Exclusive Development Ordinance and a
Stormwater Ordinance that govern development within the NCGTP. The ordinances will be
evaluated as needed to keep pace with advances in technology and to address new or growing
concerns within the NCGTP property.
7.6.9 Other Evaluations
No other aspects of NCGTP operations were evaluated at this time. It is possible that future
development will prompt evaluations of operations not currently active.
7.6.10 BMP Selection Process
The activities chosen for the good housekeeping minimum measure were selected for several
reasons. NCGTP was already implementing measures to contain hazardous wastes and train
personnel, so the activities in Table 6 are additional steps to prevent stormwater pollution.
21

7.6.11 Evaluation of success
' Goals will be set for percentage reductions of pollutant content at stormwater outfalls tied to
NCGTP operations areas. These outfalls will be monitored regularly. To ensure continued
activities to reduce pollutants from NCGTP operations, these activities will be included in the
' NCGTP stormwater master plan, currently under development.
