Subject: NPDES Permit Issuance
Permit No. NCO083887
City of Charlotte
Charlotte/Douglas International Airport
Mecklenburg County
Division staff have reviewed and approved your application for an NPDES discharge permit. Accordingly,
the Division is forwarding the subject NPDES permit. This permit is issued pursuant to the requirements
of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U.S. Environmental Protection Agency dated May 9, 1994-(or as subsequently amended).
The following items appear in this FINAL permit:
Effluent Sheet AM- Outfall 001- Jet Fuel Tank Farm
• Change in flow measurement frequency from "monthly instantaneous" to "per discharge event", and
change in the flow calculation method to reflect the manual control of the release from the retention
pond. Flow will be calculated based on the retention pond surface area and drop in pond depth
following manual release.
■ The CDIA request for reduced monitoring for TSS and O&G based on general permit conditions for
transportation facilities cannot be granted, since the general permit was not developed to cover large
airport facilities. Similarly, use of "cutoff concentrations" is reserved for general permit coverage of
smaller facilities. The facility can request reduced monitoring frequency based on a satisfactory
compliance history; however, between 2000-2001 there were several reported exceedances of the TSS
daily maximum effluent limit of 45 mg/l, and the facility is currently working to improve the
performance of the retention basin.
■ Addition of an oil and grease limit of 45 mg/1 (daily maximum) with monthly monitoring, based on
several effluent values exceeding 45 mg/1 between 2000-2001. Like TSS, oil and grease is a good
general indicator of effluent quality. This limit is consistent with other airport permits for jet fuel
storage areas.
■ Addition of a toluene limit of 11 ug/I (daily maximum). The facility reported several toluene
detections (e.g., 25 ug/l, 31 ug/l. and 150 ug/1) between 1997-2001 that exceeded the NC water
quality standard of 11 ug/l, which is based on protection of aquatic life.
■ Addition of monthly monitoring for gasoline components (B= benzene, toluene, ethylbenzene, and
xylene). This monitoring is based on the 2001 NPDES Permitting Strategy for Oil and Petroleum
Storage Facilities in NC. The jet fuel tank farm includes two 1.2 MG fuel storage tanks and six 0.42
MG fuel storage tanks. Please note that no monthly monitoring is required if there is no discharge
event for that month.
■ Addition of a pH limit with monthly monitoring. This limit is consistent with other airport terminal
permits.
■ Deletion of the semi-annual monitoring requirement for EPA Method 624 Volatile Organics, since the
most prevalent volatile constituents (BTE]Q will now be monitored monthly. Between 1997-2001,
there were only detections of benzene, toluene, and ethylbenzene based on EPA Method 624 analyses.
• Deletion of the semi-annual monitoring requirement for EPA Method 625 (Semivolatile Organics),
since there has been limited detection of EPA 625 compounds, and the area primarily stores lighter
jet fuel. There was a single detection of 2,4-dimethylphenol of 75 ug/1 in five sampling events
between 1999-2001.

■ Increase in the acute toxicity monitoring frequency from episodic to quarterly monitoring. Between
1997-2001. this discharge has exhibited variable acute toxicity, with 24-hour LC50 results ranging
from 25.5% effluent concentration to > 100% effluent concentration. If the facility consistently passes
the quarterly acute test during this permit period, then reduced monitoring will be considered during.
the following permit period.
Effluent Sheet A (2)- Outfall 002- Main Airport Runway Area
■ Correction of the sample location from "effluent" to "downstream". Due to airway safety concerns and
the diffuse nature of the runway drainage, the compliance sample has routinely been collected
outside the fenced runway area, at a location downstream of where the culvert routes combined flow
from Coffey Creek and runway runoff. Hence, this sample represents an instream station.
■ Addition of an episodic 24-hour acute toxicity monitoring requirement, to evaluate the instream
toxicity condition following de-icing activities on the main runway area.
■ Increase in monitoring frequency for ethylene glycol, from 1 /year to 3/year. Monitoring shall be
associated with de-icing/anti-icing activities. In January 2000, an ethylene glycol concentration of
935 mg/1 was reported, compared to a concentration of <10 mg/I reported in January 2001 and
February 1999. The additional monitoring will provide a more complete picture of de-icing runoff
contributions. The same increased monitoring frequency is required for NH3, unless urea is no
longer used for de-icing. Monitoring for TKN has been deleted. The monitoring frequencies are
consistent with other airport terminal permits. .
• Deletion of annual monitoring for EPA Method 624/625 compounds (volat les/semivolatiles). There
were no detections of 624/625 compounds during the last 4 sampling events between 1999-2001.
■ The CDIA request for reduced monitoring and use of "cutoff concentrations" for TSS and O&G based
on general permit conditions for transportation facilities cannot be granted, since the general permit
was not developed to cover large airport facilities.
Effluent Sheet A (3)- Outfall 003- Southeastern Runway Area
■ Addition of an episodic 24-hour acute toxicity monitoring requirement, to evaluate the instream
toxicity condition following de-icing activities on the southeastern runway area.
• Increase in monitoring frequency for ethylene glycol, from 1 /year to 3/year. Monitoring shall be
associated with de-icing/anti-icing activities. The additional monitoring will provide a more complete
picture of de-icing runoff contributions. The same increased monitoring frequency is required for
NH3, unless urea is no longer used for de-icing. Monitoring for TKN has been deleted. The
monitoring frequencies are consistent with other airport terminal permits.
■ Deletion of annual monitoring for EPA Method 624/625 compounds (volatiles/semivolatiles). There
were no detections of 624/625 compounds during the last 4 sampling events between 1999-2001.
• The CDIA request for reduced monitoring and use of "cutoff concentrations" for TSS and O&G based
on general permit conditions for transportation facilities cannot be granted, since the general permit
was not developed to cover large airport facilities.
Instream Sheet A (4)- Instream Station 004- Background
• Deletion of the pH limit, since this station is located upgradient of the airport and serves as a
background station.
• Deletion of annual TKN monitoring, which has also been deleted from downstream stations.
• Deletion of the requirement for flow calculation, which is not necessary for background chemical
characterization.
■ Deletion of annual monitoring for EPA Method 624/625 compounds (volatiles/semivolatiles). There
were no detections of 624/625 compounds during the last 4 sampling events between 1999-2001,
and similar monitoring for downstream stations has also been deleted based on consistent lack of
detection.
Miscellaneous
• The previous permit listed Charlotte Douglas International Airport as the facility owner. Ownership
has been corrected to City of Charlotte, which owns and operates the airport.
■ Please note that any future runway addition will require a major permit modification, since this will
add additional flow/pollutant loading to receiving streams. The Division needs to notice major permit
modifications in local newspapers with a 30-day public comment period, similar to the permit renewal

process. The permittee will need to send a letter request for the permit modification along with a
major modification fee of $215, and provide information pertaining to the new discharge location, size
of the new drainage area, pollutants expected, and anticipated project completion date. The NPDES
Unit understands that an EA/FONSI for this runway expansion was already completed.
Please note that any future addition of a centralized de-icing facility (with drainage to Outfall 002) will
not require an NPDES permit modification. There is already monitoring associated with de-icing
operations at both Outfalls 002 and 003, which drain the runway operations.
The facility should recheck their method of calculating flow at each outfall. Many of the monthly
flows reported are the same for each station, despite the fact that each outfall drains a different -sized
drainage area with varying impervious surface. As the Division understands it, flow is calculated at
Outfall 001 based on the drop in pond depth during the manual release, combined with the pond
surface area. For Outfalls 002 and 003, stormwater flow is calculated based on the amount of area
draining to the outfall, the amount of built -upon (impervious) area, and the total amount of rainfall.
If these flow calculation methods have changed, please update the Division with the current flow
calculation methods. As previously indicated, flow calculation for instream background station 004
will no longer be required.
The facility has already developed a comprehensive Stormwater Pollution Prevention Plan (SPPP) as
required by their NPDES permit. A Compliance Evaluation Inspection conducted by Mecklenburg
County Department of Environmental Protection (MCDEP) in May 2001 noted that the facility was
currently deficient in implementing several areas of the SPPP. The facility should recheck their SPPP
requirements, including proper documentation for stormwater qualitative monitoring events and
stormwater releases.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and fled with the office of Administrative Hearings,
6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this
permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division. Part II, EA.
addresses the requirements to be followed in case of change in ownership or control of this discharge.
The Division may require modification or revocation and reissuance of the permit. This permit does not
affect the legal requirements to obtain other permits which may be required by the Division of Water
Quality, the Division of Land Resources, the Coastal Area Management Act, or any other federal or local
governmental permit.
If you have any questions concerning this permit, please contact Tom Belnick at telephone number (919)

accordance with the requirements found in Boilerplate Part II, Section B.11.
b. Stormwater Management Plan: The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
non-structural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(1) Feasibility Study. A study addressing 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 practicable
the permittee should consider covering storage areas, material handling
operations, manufacturing or fueling operations to prevent materials exposure to
stormwater. In areas where elimination of exposure is not practicable, the
stormwater management plan shall document the feasibility of diverting the
stormwater runoff away from areas of potential contamination.
(2) Secondary Containment. A schedule to provide secondary containment for bulk
storage of liquid materials, storage of Section 313 of Title III of the Superfund
Amendments and Reauthorization Act (SARA) water priority chemicals, or
storage of hazardous materials to prevent leaks and spills from contaminating
stormwater runoff. If the secondary containment devices are connected directly
to stormwater conveyance systems, the connection shall be controlled by
manually activated valves or other similar devices [which shall be secured with a
locking mechanism] and any stormwater that accumulates in the containment
area shall be at a minimum visually observed prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation,
the description of the accumulated stormwater and the date and time of the
release shall be kept for a period of five years.
(3) BMP Summary. A narrative description of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris
control, vegetative * filter strips, infiltration and stormwater detention or
retention, where necessary. The need for structural BMPs shall be based on the
assessment of potential of sources contributing significant quantities of
pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to
be taken to limit or prevent erosion associated with the stormwater systems.
C. Spill Prevention and Response Plan (SPRP): The Spill Prevention and Response Plan
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified in the plan. 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, a SPCC plan 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 Spill Prevention Countermeasures and
Containment Plan (SPCC) with the SPRP may be incorporated by reference into the
SPRP.

Permit No. NC0083887
d. Preventative Maintenance and Good Housekeeping Program: A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.

minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified in the plan.
f. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be
documented and position(s) assignments provided.
g. Plan Amendment: The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants via a point source to surface waters. The
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee
shall submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Boilerplate Part II, Section B.11.) to the Director that the changes have been made.
h. Facility Inspections: Inspections of the facility and all stormwater systems shall occur
at a minimum on a semiannual schedule, once in the fall (September - November) and
once during the spring (April - June). The inspection and any subsequent maintenance
activities performed shall be documented, recording date and time of inspection,
individual(s) making the inspection and a narrative description of the facility's
stormwater control systems, plant equipment and systems. Records of these
inspections shall be incorporated into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in A (5) Stormwater Monitoring Requirements/Qualitative
Monitoring shall be performed in addition to facility inspections.
Implementation: Implementation of the Plan shall include documentation of all
monitoring, measurements, inspections, maintenance activities and training provided to
employees, including the log of the sampling data. Activities taken to implement BMPs
associated with the industrial activities, including vehicle maintenance activities, must
also be recorded. All required 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.

a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the .number of daily discharges sampled and/or
measured during such month. It is therefore, an arithmetic mean found by adding the
weights of the pollutant found each day of the month and then dividing this sum by the
number of days the tests were reported. The limitation is identified as "Monthly
Average" in Effluent Limitations and Monitoring Requirements in the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during the calendar week (Sunday - Saturday) on which
daily discharges are sampled and measured, divided by the number of daily discharges

by adding the weights of pollutants found each day of the week and then dividing this
sum by the number of days the tests were reported. This limitation is identified as
'Weekly Average' in Effluent Limitations and Monitoring Requirements in the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged
during a calendar day. If only one sample is taken during any calendar day the weight
of pollutant calculated from it is the "maximum daily discharge." This limitation is
identified as "Daily Maximum' in Effluent Limitations and Monitoring Requirements in
the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges
sampled and/or measured during the calendar year on which daily discharges are

SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Certified Operator
Pursuant to Chapter 90A 44 of North Carolina General Statutes, and upon classification of
the facility by the Certification Commission, the permittee shall employ a certified
wastewater treatment plant operator in responsible charge (ORC) of the wastewater
treatment facilities. Such operator must hold a certification of the grade equivalent to or
greater than the classification assigned to the wastewater treatment facilities by the
Certification Commission. The permittee must also employ a certified back-up operator of
the appropriate type and any grade to comply with the conditions of Title 15A NCAC
Chapter 8G .0200. The ORC of the facility must visit each Class I facility at least weekly
and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and
must properly manage and document daily operation and maintenance of the facility and
must comply with all other conditions of Title 15A, NCAC Chapter 8G .0200. Once the
facility is classified, the permittee shall submit a letter to the Certification Commission
which designates the operator in responsible charge within thirty days after the wastewater
treatment facilities are 500i6 complete.
2. Proper Operation and Maintenance

Boilerplate Part II
Page 11 of 17
3.- Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this permit.
4. Bmassing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a
treatment facility including the collection system, which is not a designed or
established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage
to the treatment facilities which causes them to become inoperable, or substantial
and permanent loss of natural resources which can reasonably be expected to occur
in the absence of a bypass. Severe property damage does not mean economic loss
caused by delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations
to be exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of
this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass
as required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1} Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering
its adverse affects, if the Permit Issuing Authority determines that it will meet the
three conditions listed above in Paragraph d. (1) of this section.
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors

Boilerplate Part II
Page 12 of 17
beyond the reasonable control of the permittee. An upset does not include
noncompliance to the extent caused by operational error, improperly designed treatment
facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or
improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with such technology based permit effluent limitations if the requirements of paragraph
c. of this condition are met. No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence
that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6 of this permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of
this permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and
in a manner such as to prevent any pollutant from such materials from entering waters of
the State or navigable waters of the United States. The permittee shall comply with all
existing federal regulations governing the disposal of sewage sludge. Upon promulgation of
40 CFR Part 503, any permit issued by the Permit Issuing Authority for the
utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to
incorporate applicable requirements at 40 CFR Part 503. The permittee shall comply with
applicable 40 CFR Part 503 Standards for the Use and Disposal of Sewage Sludge (when
promulgated) within the time provided in the regulation, even if the permit is not modified
to incorporate the requirement. The permittee shall notify the Permit Issuing Authority of
any significant change in its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM
Regulation, Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability,
to prevent the discharge of untreated or inadequately treated wastes during electrical power
failures either by means of alternate power sources, standby generators or retention of
inadequately treated effluent.

PROJECT NOTES
Summar9
• This is a minor permit renewal for the City of Charlotte's Charlotte/Douglas International
Airport (CDIA) located in Mecklenburg County. The CDIA is currently permitted to
discharge stormwater, used deicing fluid (glycol), and washwater resulting from airport
operations through several outfalls (see Table 1 Summary). Currently, CDIA does not
generate solids, therefore a sludge management plan is not necessary.
• The airport discharges to three different streams (Coffey Creek, UT Taggart Creek, UT Ticer
Branch) in the Catawba River Basin (030834). None of these receiving streams are listed as
impaired waters in the 2000 303(d) listing. The receiving waters are intensely urbanized
streams draining the City of Charlotte. This watershed is still characterized by Fair to Poor
water quality.

Permit Development
■ Renewal Application. The permittee submitted a Short Form C renewal application on
3/2/01. The current permit expires on 8/31/01. The airport is not classified as a Primary
Industry according to 40 CFR 122, Appendix A, and therefore a priority pollutant analysis
was not submitted.
■ Glycol/Proposed Central De-icing Facility. Glycol is currently used by several tenants for
de-icing aircraft/runways. Estimated glycol usage in 2000 was 188,381 gallons, used in
November -February. CDIA is planning to install a central deicing facility, with runoff
draining to Outfall 002. The centralized facility should enable CDIA to better control
deicing fluid usage and treatment. No firm construction schedule at this time. No future
permitting action necessary, since Outfall 002 is already monitored for glycol.
■ Proposed Runway Expansion. The permittee is planning a runway expansion that would
likely include a railroad loading/unloading facility. Stormwater runoff from this expansion
will likely drain to Coffey Creek. An EIS/ROD was completed in April 2000 for the
expansion. However, no firm construction schedule has been developed, and plans are not
finalized. Ultimately, specific discharge points, drainage areas, etc. will need to be
evaluated by the Division before any permit action to incorporate the runway expansion.
■ Outfall 001- Limits/Monitoring for Jet Fuel Tank Farm. Review of DMR data indicates that
the pollutants of concern associated with this discharge are primarily BTEX compounds
(benzene, toluene, ethylbenzene, xylene) associated with lighter jet fuel. Therefore, add
monthly BTEX monitoring, and delete semi-annual monitoring of 624-volatile/625-
semivolatile parameters. Add toluene limit based on reasonable potential to exceed
instream water quality standard. Increase aquatic toxicity test monitoring from episodic to
quarterly, based on previous data showing a wide range in acute toxicity. Add effluent limit
for Oil and Grease, and pH, which is consistent with NPDES permitting at other airport
bulk fuel storage areas (e.g., RDU).
■ Outfalls 002/003- Limits/Monitoring for Runway Areas. One of the primary pollutants of
concern at airport runways is ethylene glycol and ammonia (if urea is used) from de-
icing/anti-icing activities. Therefore, this permit adds episodic acute toxicity monitoring
during de-icing/anti-icing events to evaluate potential instream impacts, and increases the
monitoring frequency for ethylene glycol and ammonia (if urea is used) from 1 /year to
3/year, consistent with NPDES permitting at other airport runway areas (e.g., RDU). Based
on lack of detection (n=4 events) of EPA Method 624/625 compounds
(volatiles/semivolatiles) between 1999-2001, delete annual monitoring requirement.
■ Outfall 004- Monitoring for Instream Background. This is an instream background station,
used to evaluate impacts of main runway area to Coffey Creek. Therefore, delete pH limit,
which was incorrectly applied last round. Delete annual EPA 624/625 monitoring,
consistent with downstream monitoring program.
■ Stormwater Requirements. The facility has developed a comprehensive Stormwater
Pollution Prevention Plan (SPPP). A Compliance Evaluation Inspection (CEI) was conducted
by MCDEP on 5/ 16/01. The CEI noted that the facility did not have written records of
stormwater qualitative monitoring as required by the permit. The CEI also noted that
several of the stormwater pollution prevention strategies were not being implemented
according to schedule. A Notice of Violation was issued based on the CEI report.
■ Permittee Request- Outfall 001. The permittee requested that the monitoring frequency for
EPA Method 624/625 (volatile/semivolatile) parameters be reduced from semi-annual to
annual at Outfall 001, due to the intermittent nature of the discharge and infrequent
detections. As indicated above, BTEX compounds are the primary pollutant of concern
associated with the jet fuel storage and monthly monitoring has been added to the permit.
Semi-annual monitoring of 624/625 compounds has been deleted.
■ Permittee Request-Outfalls 001/002/003. The permittee requested that current effluent
limits for TSS and O&G be • revised to reflect current general permit conditions for
transportation facilities. The general permit contains cutoff concentrations for TSS and

NPDES PERMIT FACT SHEET Charlotte/Douglas International Airport
Page 6 NPDES No. NC0083887
O&G of 100 and 30 mg/l, respectively, and allows the permittee to monitor for them only
during the first and last years of the permit term, if the arithmetic mean for all results
collected during the permit coverage period is less than the cutoff concentrations. The CDIA
request for reduced monitoring for TSS and O&G based on general permit conditions for
transportation facilities cannot be granted, since the general permit was not developed to
cover large airport facilities. Similarly, use of "cutoff concentrations" is reserved for general
permit coverage of smaller facilities. The facility can request reduced monitoring frequency
based on a satisfactory compliance history; however, between 2000-2001 there were several
reported exceedances of the TSS daily maximum effluent limit of 45 mg/l. The facility is
currently working to improve the performance of the retention basin.
DMR Data.
• Outfall 001. DMR data for 2000 reports the following range in values: flow (0.08-0.26
MGD); O&G (<5-110 mg/1); TSS (8-73 mg/1); Acute toxicity (25.5%), and detections of
benzene (12 ug/1), ethylbenzene (8 ug/1), and toluene (25 ug/1). In January 2001, the
facility reported detections of benzene (50 ug/1), toluene (150 ug/1), ethylbenzene (35 ug/1),
and 2,4-Dimethyl phenol (75 ug/1).
• Instream 002. DMR data for 2000 reports the following range in values: flow (0.22-0.26
MGD); O&G (<5-6 mg/1); TSS (<10-35 mg/1); MBAS (0.12-0.3 mg/1); glycol (935 mg/1); NH3-
N (3.7 mg/1); TKN (45 mg/1). No detection of EPA 624/625 compounds.
• Outfall 003. DMR data for 2000 reports the following range in values: flow (0.22-0.26
MGD); O&G (<6 mg/1); TSS (<5-11 mg/1); MBAS (<0.1-0.2 mg/1); glycol (<10 mg/1); NH3-N
(0.1 mg/1); TKN (<0.5 mg/1). No detection of EPA 624/625 compounds.
• Instream 004. DMR data for 2000 reports the following range in values: flow (0.22-0.26);
O&G (<6 mg/1); TSS (<5-20 mg/1); MBAS 0.1-0.2 mg/1); glycol (<10 mg/1); NH3-N (0.2 mg/1);
TKN (0.7 mg/1). No detection of EPA 624/625 compounds.
• Compliance Data. There have been violations of the TSS effluent limit at 001; facility is
currently redesigning the retention basin.

ACUTE TOXICITY MONITORING (QRTRL ,
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as definitive in
E.P.A. Document EPA/600/4-90/027F entitled "Methods for Measuring the Acute Toxicity of Effluents to
Freshwater and Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales
promelas) 24 hour static test. Effluent samples for self -monitoring purposes must be obtained below all
waste treatment. The testing mill be performed mnn the first discharge from the facility duriileach quarter,
the quarters defined as the months of January -March, April -June, July -September, and October -December.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was performed,
using the appropriate parameter code. Additionally, DWQ Form AT-1 (original) is to be sent to the
following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than
30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of
the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should there be no discharge of flow from the facility during any quarter, the permittee will complete the
information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the
address cited above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened
and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will require
that a test be performed upon the next discharge event.

Tom,
As I recall, my recommendations were:
001-Increase monitoring (no limit) to "once each quarter in which there is a
discharge."
002-Standard episodic monitoring language -First five discharge events,
annually thereafter.
003-We were going to determine if this was a continuous discharge. If so,
I'd recommend determining flows and applying chronic Cerio tests
quarterly... with at least two years of monitoring prior to implementing a
limit.
If it is not continuous, then we'd apply the standard episodic monitoring
language as in 002.

Hi Matt- Hope you made it to Havana (and back)! I'll be out Feb 12-15, V but would like to get the airport draft permit together when I return.
I've got most of it put together except for the toxicity stuff. Can you
email me your recommendations for Outfall 001 (jet fuel tank farm),
Instream 002 (main runway runoff), and Outfall 003 (minor runway
runoff). I'm proposing monthly monitoring for BTEX components for 001,
and wonder whether the tox test should be bumped up to quarterly based
on past results??? For 002 and 003, I'm proposing 3/year monitoring
during deicing events for glycols/NH3 to better evaluate the runway
mpact from deicing activities. Currently there are no tox requirements
for 002/003, but it seems like there should be something (episodic?
annual? 3/year?). The RDU permit includes either annual or episodic
acute monitoring for their runway outfalls. After I incorporate your
comments, I'll send around as an internal draft before the public
notice. Thanks.

Hey Matt- I'm just starting to sort through this one, so this may not be
the only question. The airport has 3 outfalls associated with airport
activities, while Outfall 004 is an instream background. Only one
outfall (001) currently has a tox test, which is acute episodic
monitoring (first 5 events, then annual). This outfall receives
stormwater drainage from the aviation bulk fuel farm, and the stormwater
drains to an oil water separator, then to a retention pond, which then
discharges to an UT to Ticer Creek (Class C). The compliance sample is
collected as an end -of -pipe grab after the retention pond. Results for
the acute tox test from 1997-2000 are: >100, >100, 55.5, 70.7, >100,
25.5. The DMR file also lists an LC50 of 70% for a 1/30/01 sample, but
this does not appear in your Self -Monitoring Summary table. Outfall 001
has shown varying amounts of BTEX compounds, with some values exceeding
the toluene WQS of 11 ug/l. My question is what kind of toxicity
monitoring should we put in the permit renewal?

b. River Basin and Subbasin No.: Catawba 030834
C. Describe receiving stream features and pertinent downstream uses: all outfalls
discharge to dry ditches, which eventually discharge to the respective receiving
streams.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater: Intermittent discharge from all three outfalls (outfall 004
is for instream sampling only).
Outfall 001 consists of stormwater runoff from the jet fuel tank farm. All
stormwater from this area is treated through an oil/water separator and then
discharged into a retention pond, which also acts as secondary containment.
Discharges from the retention pond are through a manually operated gate valve,
which means that discharges may not coincide with a storm event.
Outfall 002 consists of stormwater runoff from the runway and tenant areas of the
airport.
Outfall 003 consists of stormwater runoff from the southeastern side of the site,
which includes a small portion of the runway and a few tenants. This stormwater
is directed through a retention pond prior to overflowing into Taggart Creek. The
NC Air National Guard also discharges into Taggart Creek under a separate
NPDES Permit.
Outfall 004. No treatment exists. CDIA is required to monitor Coffey Creek
upstream of the airport at a point designated as outfall 004 (upstream sample
point). No wastewater or stormwater is discharged through this outfall.
b. What is the current permitted capacity: Intermittent.
C. Actual treatment capacity of current facility (current design capacity): 0.036
MGD (outfall 001).
d. Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: N/A
e. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of a 0.036 MGD oil/water separator followed by a
retention pond (outfall 001).

Page Three

4.
f. Description of proposed WWT facilities: There are no proposed WWT facilities,
however, there are some changes planned for this year that may effect the renewal
of this permit. First, the de-icing facility will be relocated to the middle of CDIA.
This will allow CDIA to more accurately monitor and control de-icing fluid usage,
as well as implement BMPs that will reduce stormwater pollution. The de-icing
operation will drain to outfall 002.
CDIA also plans to construct a new runway in late 2001 or early 2002. The new
runway project will include a railroad loading and unloading facility, which will
generate additional stormwater runoff. This runoff will discharge into Coffey
Creek upstream of outfall 004. CDIA has requested that the renewed permit
include monitoring requirements for the proposed outfall, which will be phased in
once the new runway is in operation. A time schedule detailing the specific
construction sequence should be submitted by the permittee prior to permit
renewal.
g. Possible toxic impacts to surface waters: Toxic impacts potentially resulting
from the discharge of glycol (de-icing fluid) should be evaluated prior to permit
reissuance.
h. Pretreatment Program (POTWs only): Not Needed.
Residual handling and utilization/disposal scheme: Residuals generation is not expected.
Treatment plant classification: No rating.
SIC Code(s): 5171 Wastewater Code(s): 37, 39 MTU Code(s): 53000
PART III - OTHER PERTINENT INFORMATION
Is this facility being constructed with Construction Grant Funds or are any public monies
involved (municipals only)? No
2. Special monitoring or limitations (including toxicity) requests.
a. CDIA is currently required to monitor outfall 001 for EPA Method 624/625 semi-
annually. In four (4) out of eight (8) recent sampling events, only four parameters
were detected (Benzene, Toluene, Ethylbenzene, and 2,4-Dimethyl phenol). Of
the four parameters detected, Toluene is the only one that has a WQ standard.
Three of the four Toluene detections exceeded the WQ standard, which is human
health based. CDIA requests that the monitoring frequency at outfall 001 for
Method 624/625 be reduced to annually. Based on the monitoring results
provided, this Office believes that the current monitoring frequency is
appropriate and should not be changed.

Page Four
b. CDIA's current NPDES permit contains limits for oil & grease (O&G) of 45 mg/I
at Outfalls 002 and 003, and a Total Suspended Solids (TSS) limit of 45 mg/1 for
Outfall 001. The current General Permit (GP) for Transportation Facilities
contains cut-off concentrations for O&G and TSS of 30 mg/I and 100 mg/1,
respectively. In the GP, if the arithmetic mean for all results are less than the cut-
off concentrations, then the permittee only has to monitor for them in the first and
last years of the permit term. Data collected by CDIA reflects values for O&G
and TSS that are significantly less than the cut-off concentrations in the GP.
CDIA has requested that the O&G and TSS monitoring be revised to reflect the
GP monitoring requirements. Defer comment to the NPDES Unit.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4. Alternative analysis evaluation: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, Charlotte -Douglas International Airport, requests renewal of the subject
permit. The permit provides for the approval to discharge de-icing fluid, stormwater, and wash
water through three (3) outfalls. Modifications planned for CDIA during the term of the new
permit are detailed in Part II, No. 1(f). Other modifications/changes requested by CDIA are
detailed in Part III, No. 2.
Pending a final technical review of CDIA's requested changes, it is recommended that the
NPDES Permit be renewed.

Subject: NPDES Permit Renewal Application
Permit No. NCO083887
Charlotte/Douglas International Airport
Mecklenburg County
Dear Mr. Weaver:
Charlotte/Douglas International Airport (CDIA) is submitting the enclosed Short Form C for renewal
of the subject NPDES permit. The NPDES permit expires on August 31, 2001, and the permit
r� renewal application must be postmarked by March 4, 2001, as stated in your letter to CDIA dated
January 29, 2001.
Outfalls
CDIA is currently permitted to discharge used deicing fluid, storm water and washwater through
several outfalls. CDIA is currently required to monitor storm water discharges from three outfalls as
well as at a surface water location upstream of the facility.
Outfal1 001 contains runoff from the north side of the CDIA facility including the jet fuel tank farm.
(� Stormwater from the jet fuel tank farm is treated through an oil/water separator and discharged into a
�y retention pond. The retention pond is used as a means of secondary containment in the event of a
✓� spill at the tank farm and has a gate valve which must be manually opened to discharge storm water.
Therefore, storm water is discharged at Outfall 001 throughout the year and may or may not coincide
with a storm event. Discharge flow is estimated based on the area and the drop in depth of the
retention pond. Since the discharge does not correspond with a rainfall event, total rainfall and storm
duration will not be reported on the Discharge Monitoring Report. Outfall 001 discharges into Ticer
Creek.
Outfall 002 is an instream monitoring point in Coffey Creek. Outfall 002 includes storm water runoff
from the majority of the runway and tenant areas at CDIA.
Outfall 003 contains storm water runoff from the southeastern side of the CDIA facility and contains
a small portion of runway area and a few tenants. Storm water at Outfall 003 is directed through a
retention pond prior to overflowing to Taggart Creek. The North Carolina Air National Guard
located on CDIA property also discharges into Taggart Creek under a separate NPDES permit.
Charlotte/Douglas International Airport
P.O. Box 19066 Charlotte, NC 28219 704/359-4000

Mr. Charles Weaver
Page 2
March 2, 2001
CDIA is also required to monitor Coffey Creek at a point upstream of the facility, which is designated
as Outfall 004.
Facility Changes
CDIA will continue to discharge used deicing fluid, storm water and washwater. New tenants have
been added at CDIA since the 1996 NPDES permit application submittal. The operations for these
new tenants are comparable to the existing tenants.
Currently deicing operations are performed by several tenants at several locations. CDIA is planning
to install a central deicing facility in late 2001. The deicing facility will be located to the south of
Concourse A. in CDIA's midfield location. Storm water runoff from the deicing facility will drain to
Outfall 002. The centralized deicing facility should enable CDIA to more accurately monitor and
control deicing fluid usage, as well as implement consistent BMPs to reduce storm water pollution.
Construction for a new fourth runway is planned to begin in late 2001 or early 2002. Likely, a few
tenants will be added, and a tenant may be relocated. A railroad loading and unloading facility will
likely be added with this expansion. Runoff from the facility expansion will likely discharge into
Coffey Creek upstream of the current monitoring location. After plans for the expansion are
finalized, CDIA will forward those plans for your review. CDIA requests that this permit
modification be phased in with the permit renewal, so that the current permit will be automatically
expanded to cover the expansion projects. The new facilities could be eligible for coverage under the
General Permit for Transportation Facilities (NCG080000). However, CDIA would like the
discharges to be covered under our current permit for consistency. Attached is a facility drawing
showing the proposed changes. CDIA will forward additional design drawings to DWQ as they are
completed.
Monitoring Data
The NPDES permit requires that one year of monitoring data be submitted with the permit renewal
application. Tables 1 through 4 present the monitoring data for Outfalls. 001, 002, 003, and 004,
respectively.
Glycol is currently used by several tenants whose recordkeeping procedures vary, and may not
correlate to a calendar month. Estimated glycol usage is presented in Table 5 which is based on the
tenants who use the majority of glycol.

Recommended Permit Changes
CDIA is currently required to monitor Outfall 001 for the EPA Method 624/625 parameters semi-
annually. Table 6 presents a summary of eight sampling events. Only four parameters were detected
during four or fewer sampling events: benzene, toluene, ethylbenzene, and 2,4-dimethyl phenol.
CDIA does not have permit limits for these parameters. There is a water quality standard for toluene
of 11 µg/L for Class C waters. This water quality standard is human health based on a long-term
exposure and is usually limited based on an annual mean flow. Due to the intermittent nature of the
Outfall 001 discharge and infrequent detections, CDIA is recommending that the monitoring
frequency for EPA Method 624/625 be reduced to annual.

CDIA's current permit contains an oil and grease (0&G) limit of 45 mg/L at Outfalls 002 and 003,
and a total suspended solids (TSS) limit of 45 mg/L for Outfall 001. The general permit for
transportation facilities contains cutoff concentrations for 0&G and TSS of 30 and 100 mg/L,
respectively. The general permit states that if the arithmetic mean for all results collected during the
permit coverage period is less than the cutoff concentrations, then the permittee only has to monitor
for them during the first and last years of the permit term. Table 7 presents the average TSS and
0&G values for Outfalls 001 — 004 for the current permit term. The average values are significantly
below the cutoff concentrations. In addition, the average values for Coffey Creek upstream of the
facility are comparable to the average values downstream of the facility. Therefore, CDIA

recommends that the 0&G and TSS monitoring requirements be revised to reflect the general permit
conditions.

SUBJECT: Expansion Explanation for the New Runway Area at CDIA
The following is a brief summary regarding expansion activities at Charlotte/Douglas International
Airport. The attached drawings reflect this information. Please note that the 8.5x11 drawing was
included for convenience. This drawing does not reflect the intermodal rail yard, though the
24x36 drawing does.
1. The dark green areas reflect property that is being purchased by CDIA for expansion activities.
2. The light green areas reflect existing CDIA property that our current NPDES permit covers.
3. The primary area of expansion is to the west, between existing airport property and I-485.
This area will contain a new, third parallel runway and the new rail yard. Only one CDIA
stormwater tenant will be relocated due to this expansion.
4. CDIA would like the new NPDES Permit to be written with an automatic expansion clause of
some type. The idea is to expand the permit coverage as the new runway is designed and
built, without having to redo this entire permitting process. This should ease the burden on
DENR and make things more efficient.
5. As plans become formalized, more specific information will be forwarded to DENR so that
outfall locations, etc. can be verified and adjustments made as might be necessary.
CDIA thanks you for your assistance in this matter and if there are any questions or comments,
please call me at 704-359-4000.

Darren,
I appreciate you handling this call. I'll ask Charles to print out a copy
of this e-mail and place it in the file. Normally, the Mecklenburg County
EPD get an opportunity to look at our major draft permits in their county.
However, this will ensure that they'll get a copy. I don't know whether or
not the application has come in, but it is unlikely that we'll draft the
permit until January or February at the earliest.
