Subject: NPDES Renewal Application Addendum
Charlotte Douglas International Airport (CLT)
NPDES # NC0083887
5601 Wilkinson Boulevard
Charlotte, North Carolina 280208
Dear Dr. Adaryani,
Charlotte Douglas International Airport (CLT) submits this addendum in response to your email
correspondence of September 28, 2022, requesting supplemental information be provided in
support of CLT's NPDES Renewal Application. Each request is itemized and addressed below.
REQUEST: Please provide a current list of tenants in the airport facility and specify the type of
operations performed (e.g., type of business, business description, and SIC/NAICS code).
RESPONSE: See Attachment A — CLT Tenants.
REQUEST: Airport facilities could have activities and pollutant sources that contain PFAS and
can come into contact with stormwater discharges. Per and polyfluoroalkyl substances (PFAS)
are a group of man-made chemicals that include PFOA, PFOS, GenX and many other chemicals.
In the light of upcoming PFAS related regulations and related liabilities, please provide updated
BMPs that addresses any possible release of PFAS. For example, BMP #13 on firefighting foam
discharge, suggest "discharge foam waste to a sanitary sewer...". Such language and similar ones
should be modified, with practices to eliminate any possible PFAS discharge or be responsibly
contained. You can consult "Industrial Stormwater Fact Sheet Series, Sector S" (U.S. EPA Office
of Water, EPA-833-F-06-034, February 2021) for more details.

RESPONSE: See Attachment B — Updated BMP #1, BMP #8, BMP #10, BMP #12, and BMP #13.
REQUEST: Provided BMPs should be updated to address any source of pollution from roof areas
that may be subject to drippage, dust or particulates from exhausts or vents or other sources of
pollution.
RESPONSE: See Attachment B — Updated BMP #2, BMP #7, BMP#9, BMP#10, and BMP #12.
REQUEST: Please elaborate if the current provided BMPs covers all the activities by all tenants
affecting stormwater.
RESPONSE: Tenant facilities with stormwater discharges associated with industrial activities are
covered under the existing NPDES permit. Stormwater inspections are conducted semi-annually
at each tenant facility that conducts industrial activities at CLT. All tenant and airport -operated
facilities conducting industrial activities are required to implement specific Best Management
Practices (BMP) to prevent potential pollutants at their facilities from entering the CLT storm drain
collection system. Elimination of non-stormwater discharges is also required of all tenants, as
indicated in BMP #1. The provided BMPs cover all tenant industrial activities performed at CLT
that have the potential to degrade stormwater. CLT provides annual stormwater pollution
prevention training and requires attendance at the annual trainings each December. The annual
stormwater pollution prevention training information is provided to several thousand CLT
employees each year.
REQUEST: Please elaborate on any existing AFFF system and its operation.
RESPONSE: In accordance with FAA requirements, CLT has AFFF on all aircraft crash trucks and
stores extra AFFF at each of the airfield fire stations in order to be available in the event of an
actual aircraft emergency. For testing and training exercises, CLT has modified the nozzles of the
fire suppressant hoses and also has a containment truck on site to collect and dispose of any
discharge. These containment trucks utilize a closed system, therefore no AFFF is released to the
environment for annual testing or FAA compliance demonstration. In addition, each hanger where
aircraft maintenance is performed has a fire suppression system with AFFF, as does the fueling
area of the Consolidated Rent-A-Car Center (CONRAC). Each of these systems is independent of
any other system and has its own supply of AFFF on site. These systems are a monitored so that
any activation automatically results in notification to the fire department. Most of the newer
systems have a pre -notification alarm that will sound for 15 seconds prior to the actual release or
discharge and has a manual override "kill switch" to prevent the discharge if it is determined that
there is no fire present.

REQUEST: According to preliminary results obtained from Division of Waste Management
(DWM), there is confirmed pollution on the east part of the airport. Please sample and report
(one time) for ALL PFAS compounds in EPA's draft method 1633 (Table 6), analyzed with same
method, for following outfalls: 001, 002, 003, 004, R23, ANG, Taggart creek, T-Hangar, 003, Air
Cargo, Sentry Post, 36R, F, H and K. This list covers representative outfalls in current permit as
well. The sampling should be done for a measurable storm event as defined in Part II, Section B
of current permit. The analysis should be done by a certified laboratory similar to those required
by NPDES permit pursuant to 40 CFR 136.
RESPONSE: CLT is unaware of any current regulations that establish a practical quantification limit
(PQL) standard or a health advisory for PFAS that is appliable to the surface water 2B quality
standards relevant to CLT's NPDES permit. CLT understands proposals are being considered to
designate some PFAS chemicals as hazardous substances, but that such action has not yet been
taken. If NCDENR provides CLT with a reference to its authority for requiring surface water
sampling, together with guidance on the applicable PQL, CLT will revisit this request. Such
information is needed in order for CLT to define a scope of professional services for laboratory
testing, develop an appropriate budget for such services, and prepare a strategic approach for
dealing with public records requests that may arise as a result of the sampling.
REQUEST: In EPA's Form 2C for outfall 001, in tables A, B and C, and sections 7 through 12
please correct provided information. Please note that, Petroleum Storage is not considered
Primary industry.
RESPONSE: See Attachment C — Revised EPA Form 2C.
REQUEST: Please provide sizing information of "Water flow line Drawing" for each operation.
RESPONSE: See Attachment D — Equipment and System Drawings.
REQUEST: In EPA's Form 2F for outfall 001, in sections 7 through 11 and tables A-D, please
provide necessary information.
RESPONSE: See Attachment E — Revised EPA Form 2F.

ELIMINATION OF NON -STORM WATER
DISCHARGES TO. STORM DRAIN
PURPOSE:
Existing discharges: Eliminate non -storm water discharges to the storm
water collection system. Non -storm water discharges can be classified as
follows: 1) Activity -based (subtle), and 2) Overt (hard pipe connection).
Activity -based non -storm water discharges may include wash water, and
spillage. Overt non -storm water discharges may include process wastewater,
treated cooling water, and sanitary wastewater.
Prevention of illicit connections: Prevent improper physical connections to
the storm drain system from sanitary sewers, floor drains, industrial process
discharge lines, and wash racks through education, developing project
approval conditions, and performing both construction phase and post -
construction inspections.
GENERAL APPROACH:
Identification of Activity -Based (Subtle) Discharges:
The following techniques may be used to identify activity -based non -storm
water discharges to the storm water collection system:
✓ Perform frequent activity inspections to identify non -storm water
discharges — stagger inspection times to cover all work periods.
✓ Perform visual inspections of discharge points to the storm drain system —
observe uncharacteristic volumes, colors, turbidity, odors, deposition,
staining, floatables, and foaming (AFFF) characteristics of any flow.
APPROACH TO FUTURE FACILITIES AND UPGRADES:
Design of New Facilities and Existing Facility Upgrades
✓ Perform inspections during the design review and project construction
phases to ensure drainage, wastewater, and water supply connections are
correct (no cross connections or illicit hookups).
✓ Develop a set of as -built prints for all projects. Keep a set of the prints at
the facility.
✓ Design projects to include adequate waste repositories at locations near
waste origin points.
✓ Provide adequate and appropriately designed facilities for functions such
as steam cleaning, degreasing, painting, mechanical maintenance,
chemical/fuel storage and delivery, material handling, waste handling and
storage, lavatory service, and food preparation.

WASTE/GARBAGE HANDLING AND DISPOSAL
Good Housekeeping (contd)
✓ Schedule waste pickup as frequently as necessary to keep storage of waste to a minimum and to
avoid overloaded/overfilled disposal containers.
✓ Minimize spills and fugitive losses such as dust or mist from loading areas.
✓ Maintain a minimal inventory of required chemicals to reduce the magnitude of potential spills and limit
waste generation.
✓ Track waste generation:
- Characterize waste streams.
- Evaluate the process generating the waste for pollution prevention opportunities.
- Maintain accurate information on waste streams using manifests, bills of lading, biennial reports,
permits, environmental audits, SARA Title III reports, emission reports, Material Safety Data
Sheets (MSDS), NPDES discharge monitoring reports, inventory reports, data on chemical spills,
and emissions data.
✓ Find substitutes for harmful chemicals.
✓ Properly dispose of unusable chemical inventory.
Physical Site Usage
✓ Segregate and separate wastes.
✓ Avoid locating waste handling and storage in areas with storm drain inlets/catch basins.
✓ Locate waste storage areas beneath existing cover, if possible.
Structural Controls
✓ Enclose or berm waste storage areas, if possible, to prevent contact with run-on or runoff.
Garbage Collection Areas
✓ Design facilities to provide shelter and secondary containment for dumpsters.
✓ Use covered dumpsters and keep them closed.
✓ Use only dumpsters with plugged drain holes to prevent leaks from waste materials.
✓ Do not dispose of liquid wastes into dumpsters. Completely drain liquid waste containers prior to
disposal.
✓ Perform dumpster cleaning in designated areas that are bermed to contain wash water for a
subsequent disposal or discharge to the sanitary sewer. Ramp scrubbers are effective in removing
wash water from paved areas. Dispose of or recycle all fluids collected.
Contingency Response
✓ Maintain adequate supplies of spill response equipment and materials in accessible locations near
areas where spills may be likely to occur.
✓ Equip waste transport vehicles with spill containment equipment.
