Permit No. NCS000588
PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and p zmittndco-permittees shall implement a Stormwater
Pollution Prevention Plan (SPPP).
1. The SPPP4+w-P4 -} must include Best Management Practices (BMPs), economically
reasonable and appropriate in light of current industry practices, that are selected,
designed, installed, implemented and maintained in accordance with good engineering
practices to eliminate or reduce pollutants in the permittee's discharge. The 4,-HSPPP must
identify all potential sources of pollution that may reasonably be expected to affect the
quality of stormwater discharges; describe and ensure implementation of practices used to
eliminate or reduce pollutants in stormwater discharges; and ensure compliance with the
terms and conditions of this permit.
2. The P+,++iSPPP shall include, at a minimum, the following items:
a. The P-1i"45PTP shall include a list identifying each area where industrial materials or
activities are exposed to stormwater. Industrial materials or activities include, but
are not limited to: material handling equipment or activities; industrial machinery;
raw materials; industrial production and processes; intermediate products,
by-products, final products and waste products. Material handling activities include,
but are not limited to: the storage, loading and unloading, transportation, disposal,
or conveyance of raw material, intermediate products, final products and waste
products.
b. The PlaH= shall include a list of the name(s) of all surface waters that receive
discharges from the permittee's site. The permittee must provide the size and
description of wetlands or other special aquatic sites that may receive discharges
from the airport. If there are discharges through any publicly owned or operated
storm sewer system, the Dl�,,,SP>?P must identify the publicly owned or operated
storm sewer system.
C. The P4a*SPPP shall include the identity of any receiving water into which the
permittee discharges.
d. The P4 + i5PPP shall include a list and locations where reportable spills or leaks of
pollutants that have occurred at the facility during the three previous years.
e. The P4,K45RH shall include the location(s) and/or descriptions where potential
spills and leaks could occur that could contribute pollutants to stormwater
discharges, and the corresponding outfall(s).
For each area where industrial materials or activities are exposed to stormwater,
the P4R= shall include a narrative description of storage practices, loading and
unloading activities, outdoor process areas, dust or particulate generating or
control processes, and waste disposal practices. The 0imSPPP shall include a
narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge from each outfall.
Page 5 of 4-5"

Permit No. NCS000588
g. The 44a41SPPP shall 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). Commercial tenants or other fixed -based operations
that conduct any of the operations listed in the previous sentence shall be
considered co -permittees under this Hermit, regardless of whether they are listed in
Section C of Part I or not and must provide to the Airport Authority for inclusion
in the Airport Authority's SUP all of the above information. If deicing chemicals
are used, the permittee must maintain a record of the types (including the Material
Safety Data Sheets [4949} ]) used and the monthly quantities of deicing material
only, not the deicing and water mixture, either as measured or estimated. This
includes all deicing chemicals, not just glycols and urea (e.g., potassium acetate),
because large quantities of these other chemicals can still have an adverse impact
on receiving waters. Commercial ten -ant -5; ^ other F:.,^a-h^-s^,l ^ ...,tiOHS *"^*

and must pr-eyide�_he
inf-Arm-ati en to the _air -per -t authority for- inelusion in the air -part author-ity's 121an
The pollutant list must include all significant materials, including any hazardous
substances or oil handled, treated, stored, or disposed of that have been exposed to
stormwater in the 3 years prior to the date the ala-n51W was prepared or amended.
h. Site Plan. The permittee shall mare and maintain as a hart of the SPPP a site plan_
(the Site Plan), which shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination
of stormwater discharges. The s4+e 4R-gSitP1an shall contain the following:
(i) The size of the property in acres.
(ii) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters within 1 mile of the site, the name of the receiving
water(s) to which the stormwater outfall(s) discharges, or if the discharge is
to a municipal separate storm sewer system, the name of the municipality
and the ultimate receiving waters, and accurate latitude and longitude of the
point(s) of discharge.
(iii) A site map drawn to scale (including a distance legend) showing: the site
property boundary, on-site and adjacent surface waters and known
wetlands, industrial activity areas (including storage of materials, disposal
areas, process areas, loading and unloading areas, storage tanks, fueling
stations, vehicle and equipment maintenance and/or cleaning areas,
machinery, access roads and tracks, transfer areas for substances in bulk,
locations used for the treatment, storage or disposal of wastes), locations of
all stormwater conveyances including ditches, pipes and swales;
stormwater inlets and outfalls, building locations, locations of all existing
structural and source control BMPs, the location and extent of significant
structures and impervious surfaces, and the percentage of each drainage
area that is impervious), and the drainage areas for each outfall. The site

Permit No. NCS000588
map (or alternatively the general location map) shall identify whether any
receiving waters are impaired (on the state's 303(d) list of impaired
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(iv) Locations of any storage piles containing salt used for deicing or other
commercial or industrial purposes. Storage piles of salt or piles containing
salt used for deicing or other commercial or industrial purposes, must be
enclosed or covered to prevent exposure to precipitation. The permittee
must implement appropriate measures (e.g., good housekeeping, diversions,
and/or containment) to minimize exposure resulting from adding to or
removing materials from the pile. Piles do not need to be enclosed or
covered only if stormwater from the pile is not discharged directly or
indirectly to waters of the United States or discharges from the piles are
authorized and controlled under another NPDES permit.
(v) Locations of aircraft and runway deicing operations; fueling stations;
aircraft, ground vehicle and equipment maintenance/cleaning areas;
storage areas for aircraft, ground vehicles and equipment awaiting
maintenance.
BMP's. The P4a44= shall contain a narrative description of the best .,,.,nagempi4t
p e,-�BMa employed which control or minimize the exposure of significant
materials to stormwater, including structural and nonstructural measures. The
44a4+5=P shall describe the type, location and implementation of all BMPs for each
area where industrial materials or activities are exposed to stormwater.
kFeasibili StudX. The SPPP shall include a review of the technical and
economic feasibility of changing the methods of operations and/or storage
practices to eliminate or reduce exposure of materials and processes to stormwater.
Wherever practical, the permittee and co-Iermittees shall prevent exposure of all
storage areas, material handling operations, and manufacturing or fueling
operations. In areas where elimination of exposure is not practical, the i24iSPPP
shall document the feasibility of diverting stormwater runoff away from areas of
potential contamination.
L k. -Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage of Section 313 of Title III of
the Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals; and storage of hazardous substances, in order to prevent leaks and spills
from contaminating stormwater runoff. A table or summary of all such tanks and
stored materials and their associated secondary containment areas shall be
maintained. If the secondary containment devices are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually
Page 7 of 445A$

Permit No. NCS000588
activated valves or other similar devices (which shall be secured closed with a
locking mechanism), and any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by the
material stored within the containment area. Records documenting the individual
making the observation, the description of the accumulated stormwater, and the
date and time of the release shall be kept by >hc-permittee and/or co -permittee, as
appropriate, for a period of five years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit.
M. Unauthorized Discharges. Discharges to waters of the United States that are not
authorized by this permit, or by another NPDES permit, or by other authorization or
permission are unlawful and must be eliminated. The R}SPPP must include a
certification by permittee that all discharges (i.e., outfalls) have been tested or
evaluated by the permittee for the presence of non-stormwater discharges, and that
all unauthorized discharges have been eliminated. The permittee shall re -certify
annually that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The ^r*if cation statem@PA and each co-nermittee
shall certify annually to the permittee that there have been no unp .rmi d
discharges to the waters of the United States and permittee -may rely on those
co- ermittee certifications. These certification statements will be signed in
accordance with the requirements found in Part III, General Conditions, Section B,
Paragraph 5 and must include:
i The date of any testing and/or evaluation,
ii A description of the evaluation criteria or testing method used,
iii A list of the outfalls or onsite drainage points that were directly observed
during the test,
iv A description of the results of any test and/or evaluation for the presence of
non-stormwater discharges, i.e., identification of unauthorized discharge(s)
origin and composition,
v The action(s) taken to eliminate unauthorized discharge(s), if any were
identified. For example, a floor drain was sealed, a sink drain was rerouted
to sanitary, or an NPDES permit application was submitted for a cooling
water discharge.
n. Spill Prevention and Response Plan. The nermittee shall develop and implement a
Spill Prevention and Response Plan (SPRP) which shall be a part of the SPPP and
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility: and which nermittee shall 1rovide to all co -permittees.
Facility personnel (or the team) responsible for implementing the SPRP shall be
Page 8 of 4 48

Permit No. NCS000588
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 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.
Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program [PMGH Programl shall be developed
and implemented by the permittee.- The pr-OgFa » and any affected co -permittee:
Program. The rlermittee's PMGH Program shall list all stormwater control systems,
stormwater discharge outfalls, all on-site and adjacent surface waters and wetlands,
industrial activity areas (including material storage areas, material handling areas,
disposal areas, process areas, loading and unloading areas, and haul roads), all
drainage features and structures, and existing structural BMPs.The ; any=
Qnermittee's PMGH Program shall include any such information as is relevant or
required by the nermittee's PMGH Program All such PMGH Truxams shall
establish schedules of inspections, maintenance, and housekeeping activities of
stormwater control systems, 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 PFOgFa+i+PMGH Program. Timely compliance with the
established schedules for inspections, maintenance, and housekeeping shall be
recorded in writing and maintained.
P. Employee Training. The P1@-RAll2L- shall include a per- +4teean employee
stormwater training program. The Per—mue mittee must include a schedule for
all types of necessary training. Each co -permittee shall maintain its own training
program and a r-eeaFarecords of its training program, which shall be consistent with
the nermittee's training program. All permittee and co -permittee employees who
work in areas where industrial materials or activities are exposed to stormwater, or
are responsible for implementing activities identified in the P4a-n5PPT (e.g.,
inspectors, maintenance personnel), must participate in annual training. Training
must cover the components and goals of the 1'�at+45PP_!J and include spill response,
good housekeeping, material management practices, and BMP operation and
maintenance. The annual training shall be documented by the signature and printed
or typed name of each person.
Page 9 of 4-iM

Permit No. NCS000588
q. Responsible Party. The >2Ia44SPPP shall identify the permittee staff members (by
name or title) responsible for developing, implementing, maintaining, revising and
ensuring compliance with the PSPPP. Specific responsibilities of each staff
individual must be identified and listed in the 1�i+o M. Co -permittees shall timely
provide the same information to permittee.
Facility Inspections. Inspections of the facility and all stormwater systems shall
occur as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year (January
to June), and once during the second half (July to December), with at least 60 days
separating inspection dates (unless performed more frequently than
semi-annually). The Director may require increased inspections and €'
^v_A1u^*i^4sSPPP re-evaluations as necessary. 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 systems, equipment, and systems. k'+niteeThe permittee can
inspect any co -permittee facility in implementing this program, but co -permittees
must develop and implement their own Preventive Maintenance and Good
Housekeeping Program as appropriate for their facility, but, in any event, if
requested by the Director or the permittee.
3. Implementation. The permittee shall implement the and each co -permittee shall
implement such Plan plan as it is required to prepare and implement under this permit.
Implementation of the P4a5EU shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to employees,
including the log of the sampling data and a record of actions taken to implement BMPs
associated with the industrial activities. Such documentation shall be kept on-site for a
period of five years and made available to the Director or the Director's authorized
representative immediately upon request. The permittee must maintain all BMPs in
effective operating condition at all times. Failure to do so is a violation of this permit. The
Pla-B= must describe procedures and a regular schedule for preventive maintenance of
all BMPs, including the amount of time required for maintenance and repair, and what
back-up practices are in place should a run-off event occur while a BMP is off-line.
Nonstructural BMPs must also be diligently maintained (e.g., spill response supplies
available, personnel trained). BMPs that are not operating properly must be repaired
before the next anticipated storm event. If maintenance prior to the next storm event is not
possible, maintenance must be completed as soon as possible, and the permittee must
document the justification for the extended repair schedule. In the interim, the permittee
must have back-up measures in place to ensure that the quality of the stormwater
discharge is not diminished. The permittee must document all BMP maintenance and
repairs. Dates of regular maintenance should be documented. For repairs, the date of
deficiency discovery and the date on which the BMP was restored to full -function should
also be documented.
4. PSPPP Review and Amendment.
a. The permittee and co -permittee shall review and amend 4++P-laa;its SPPP 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
Page 10 of4�,H

Permit No. NCS000588
deficiencies in BMPs; an inspection by a local, State, or Federal official determines
that modifications to the P4anSPPP are necessary; or there is a spill, leak or other
release; or any time there is an unauthorized discharge. The permittee shall
provide copies of any amended Plan to ea pe-Hiitteef SPPP to the Director and all
co -permittees, and co -permittee shall provide a cogv of any amended lap to
permittee Permittee may provide a covey of any co-nermittee's plan to the Director.
New co -permittees shall provide certification of non -in writing of receipt of the plan
and the absence of stormwater discharges.
b. All aspects of the P4a*5PPP shall be reviewed and updated on an annual basis. The
annual update shall include an updated list of significant spills or leaks 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 been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a re-evaluation of the effectiveness of the BMPs listed in the BMP Summary
of the Stormwater Management P4an52PP.
C. SPPP modifications must be made within 30 calendar days after discovery,
observation or event requiring a modification. Implementation of new or modified
BMPs must be initiated before the next storm event if possible, but no later than 60
days after discovery, 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.
d. If the Pon= modification is the result of a release or unauthorized discharge, the
permittee and/or co -permittee, as appropriate, 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 of five years and
made available to the Director or his authorized representative immediately upon
request.
e. The Director may notify the permittee and co-p-e..inermittees when the
P -i+ p= does not meet one or more of the minimum requirements of the permit.
The notification will identify specific provisions of this permit that are not being
met, and may include required modifications to the ^ermittee's Pla 4
stipulated deadlines, additional monitoring requirements and special reporting
requirements. The permittee and co -permittee, as appropriate, shall provide
certification in writing (in accordance with Part III, General Conditions, Section B,
Paragraph 5) to the Director that the changes have been made.

SECTION E: MINIMIZATION OF THE DE-ICING MATERIALS IN STORMWATER
Facilities which conduct aircraft and/or runway (including taxiways and ramps) deicing/anti-icing
operations shall:
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.
2. Evaluate whether excessive application of deicing chemicals occurs and adjust as
necessary, consistent with considerations of flight safety.
Produce and implement a plan for the minimization of the release of materials used for
deicing into the stormwater system. This plan shall address, as a minimum:
a. The current use and practices employed at the airport for the control and
minimization of entry of the deicing materials into the stormwater system;
b. 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 deicing
materials; and
C. Feasible alternatives to the use of 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.
4. 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 ,a -i+ 44,44 tyAirnort Authority and each
co -permittee 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.
Annual usage rate of deicing/anti-icing chemicals shall be reported annually to the state.
The Division may require facilities that conduct aircraft and/or runway (including taxiways
and ramps) deicing/anti-icing operations to apply for an individual permit.

SECTION F: MINIMUM MONITORING AND REPORTING REQUIREMENTS
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Water Quality:
If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b. Qualitative monitoring for color, odor, solids, foam, outfall staining, visible sheens and
dry weather flow shall be performed at all stormwater discharge outfall locations. All
qualitative monitoring shall be documented and records maintained with the
SwFin atei- v„lluti n Pre, 'entie 4 nSPPP Qualitative monitoring of stormwater
outfalls does not need to be performed during a representative storm event. Qualitative
monitoring will be performed twice per year, once in the spring (April -June) and once in
the fall (September -November).
C. Stormwater samples collected to meet the analytical monitoring requirements of this
permit shall be collected from a discharge resulting from a representative storm event
unless otherwise specified. Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit.
d. Detergents used outdoors shall be biodegradable. The pH of the discharge shall be in the
range of 6 to 9 standard units.
e. Analytical results from sampling during the final year of the permit term shall be
submitted with the permit renewal application.
This permit regulates stormwater discharges associated with industrial activity.
Non-stormwater discharges allowable in the stormwater conveyance system include:
(1) All other discharges authorized by an NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, waterline and fire hydrant flushing, water
from footing drains, flows from riparian habitats and wetlands.
(3) Discharges resulting from fire -fighting or fire -fighting training.
g. Glycol and Urea Usage. The permittee shall be responsible for summarizing the amount
of glycol (and urea if applicable) dispensed each month for de-icing/anti-icing activities,
and submit this data on an annual basis. This information shall be submitted with the
February monthly DMR, covering the previous calendar year.

PART VI DEFINITIONS
1. Act
See Clean Water Act.
2. Adverse Weather
Adverse conditions are those that are dangerous or create inaccessibility for personnel,
such as local flooding, high winds, or electrical storms, or situations that otherwise make
sampling impractical. When adverse weather conditions prevent the collection of samples
during the sample period, the permittee must take a substitute sample or perform a visual
assessment during the next qualifying storm event. Documentation of an adverse event
(with date, time and written narrative) and the rationale must be included with your SPPP
records. Adverse weather does not exempt the permittee from having to file a monitoring
report in accordance with the sampling schedule. Adverse events and failures to monitor
must also be explained and reported on the relevant DMR.
Allowable Non-Stormwater Discharges
This general permit regulates stormwater discharges. Non-stormwater discharges which
shall be allowed in the stormwater conveyance system are:
a. All other discharges that are authorized by a non-stormwater NPDES permit.
b. Uncontaminated groundwater, foundation drains, air -conditioner condensate without
added chemicals, springs, discharges of uncontaminated potable water, waterline and
fire hydrant flushings, water from footing drains, irrigation waters, flows from riparian
habitats and wetlands.
c. Discharges resulting from fire -fighting or fire -fighting training, or emergency shower or
eye wash as a result of use in the event of an emergency.
4. Best Management Practices (BMPs)
Measures or practices used to reduce the amount of pollution entering surface waters.
BMPs may take the form of a process, activity, or physical structure. More information on
BMPs can be found at: http://cfpub.epa.gov/npdes/stormwater/menuofbmps/index.cfm.
S. Bypass
A bypass is the known diversion of stormwater from any portion of a stormwater control
facility including the collection system, which is not a designed or established operating
mode for the facility.
