January 2022 Analytical Monitoring; De -Icing Events: 1/16/2022, 1/22/2022, & 1/29/2022
Charlotte Douglas International Airport NPDES Permit #NC0083887
To comply with the monitoring requirements established by NPDES Permit #NC0083887, Charlotte Douglas International
Airport (CLT) contracted S&ME, Inc. to perform analytical monitoring for three separate qualifying de-icing events, all of which
occurred over consecutive weekends in January during the 2021-2022 winter season. The three enclosed discharge monitoring
reports (DMRs) provide data compiled from three separate letter reports presented by S&ME (Attachments A, B, and C).
Unfortunately, due to shipping delays outside of CLT s control, acute toxicity samples taken during the first event were either
discarded or analyzed out of hold time. Acute toxicity samples taken for the two subsequent qualifying de-icing events did not
experience any significant shipping delays and were analyzed within the appropriate hold time.
Analytical monitoring results which have exceeded the benchmark values established by Permit NC0083887, although not
permit limits, will be addressed in accordance with the tiered response chart included therein. To further comply with said
permit, this letter serves as written notification to the Division Stormwater Permitting Unit and the Regional Office Supervisor
that acute toxicity samples collected on January 31, 2022, from Outfall 003 and 004, failed to meet toxicity benchmark levels.
Based on S&ME's field notes and consequent stormwater management inspections, no definite cause for either failure could be
determined, but it should be noted that Outfall 004 serves as CLT's in -stream background station and represents influent
stormwater not impacted by CLT activities. It should also be noted that CLT continues to practice a strict de-icing discharge
monitoring program wherein samples are taken for all permit identified analytes from every representative outfall for the first
four qualifying de-icing events each cold -weather season and monthly thereafter, so long as a qualified de-icing event occurs.
CLT staff and contractors strive to maintain compliance with applicable NCDEQ regulations, our current individual NPDES
permit, and the provisions of the Clean Water Act. Should you need additional information regarding analytical monitoring
during de-icing events at CLT, please feel free to contact me.

S&ME Project No. 22350038A
S&ME, Inc. (S&ME) submits this Summary of National Pollution Discharge Elimination System (NPDES) Permit
required sampling, post -deicing activities conducted at the Charlotte Douglas International Airport (CLT). This
summary documents the field activities performed and presents the laboratory analytical data of selected outfalls
sampled around the perimeter of the CLT. The sampling services were performed in general accordance with the
Agreement for Professional Services between the City of Charlotte c/o Aviation Department and S&ME effective
April 26, 2019 ('the Agreement").
Project Background
Based on information provided to S&ME on January 13, 2022, we understand that CLT is required to perform
NPDES monitoring at Outfalls 002, 003 004, F, H, and K as shown on the attached Sample Location Map Figure 2,
provided by CLT. Per NPDES wastewater and stormwater permit NC0083887, discharge monitoring sampling with
in -stream field parameter readings is required within 72 hours following de-icing activities of aircraft and surfaces
at CLT. CLT provided S&ME with a copy of NPDES permit NC0083887, the NCDEQ requested analytical
parameters list, and various maps of CLT showing outfall locations.
Summary of Sampling Activities
On January 14, 2022, Mr. Brian Wilson with S&ME met with Mr. Joshua Eller with CLT on -site. Mr. Eller escorted Mr.
Wilson to the outfall locations identified for sampling.
On January 18, 2022, S&ME personnel visited CLT and collected grab samples from outfalls 002, 003, 004, F, H,
and K for the following analysis*
• Propylene Glycol (milligrams per liter [mg/L])
• Ethylene Glycol (mg/L)
• Biochemical Oxygen Demand (mg/L)
• Chemical Oxygen Demand (mg/L)
• NH3 — Nitrogen (mg/L)

• pH (field reading) (Standard Units)
• Acute Toxicity (Ceriodaphnia dubia, 48 hour static test) (Pass/Fail)
Outfall samples were collected in laboratory provided sample containers, labeled with site identification (location,
sample time, requested analysis, etc.), recorded on a laboratory provided Chain of Custody, and placed in a cooler
of ice
At each outfall location, concurrent with outfall sample collection, in -stream analytical monitoring of the receiving
stream was performed. Field readings for the following parameters were collected
• Dissolved Oxygen (mg/L)
• Turbidity (Nephelometnc Turbidity Unit [NTU])
• pH (Standard Units)
Field measurements and general observations were recorded and are included in the Attachments
Collected samples were packaged in coolers of wet ice and transported or shipped under Chain of Custody
protocols to North Carolina accredited analytical laboratories. Wet chemistry analytical services were transported
by a Pace Analytical Laboratories (Pace) courier to Pace Charlotte, North Carolina. Bioassay analysis (acute toxicity)
was performed by Pace subcontract laboratory ETT Environmental (ETT) in Greer South Carolina. The bioassay
samples were shipped FedEx priority overnight shipping by S&ME on January 18, 2022, to meet the 36-hour hold
time analytical requirements for acute toxicity testing.
On January 19, 2022, at 4:34 p.m., Pace provided S&ME with FedEx Tracking update information indicating that
the bioassay samples had not yet been delivered to ETT.
On January 20 2022, at 10:17 a.m., S&ME received notification that the bioassay samples had been delivered to
ETT. S&ME notified CLT that the samples had been received at ETT out of hold time. CLT requested that the
samples be analyzed although they were received out of hold time requirements. S&ME notified Pace to authorize
ETT to analyze the received bioassay samples. Pace contacted ETT and was notified that ETT personnel had begun
disposing of the samples and samples Outfall 002 and Outfall F had been discarded. ETT was instructed to analyze
the remaining samples for outfalls 003, 004, H, and K
FedEx shipping receipts, tracking information, and email correspondence between S&ME and Pace are included in
the Attachments.

Discussion
Bioassay samples collected on January 18, 2022 were received by ETT on January 20, 2022 out of laboratory
method hold time due to shipping/delivery delay incurred or caused by FedEx. Upon receiving the out of hold
samples, ETT discarded two samples without authorization. CLT requested that Acute Toxicity laboratory testing
be performed on the remaining four samples (Outfalls 003, 004, H, and K) to demonstrate compliance with NPDES
sampling requirements. Receipt of samples out of hold time and the unauthorized disposal of samples could not
be controlled by CLT, S&ME, or Pace.

This message originated outside of S&ME. Please report this as phishing if it implies it is from an S&ME employee.
Brian,
This is a follow up to our phone conversation and my conversation with ETT.
1. The remaining 4 samples are being processed and will be analyzed.
2. The organisms you need for this test are in stock all of the time. They do not need to special order.
3. They don't need much prior notice before sample submittal unless it's going to fall on a weekend.
4. They also don't need much notice for courier coordination. They most likely will be able to accommodate.
Thanks,

Good afternoon, Brian. This is a follow up to our conversation from earlier.
The bioassay samples arrived at ETT today due to a Fedex delay. The samples are out of hold currently.
I had reached out to ETT to not discard any samples until I got back with them, but it was too late. They have discard the
sample volume for outfall 002 and F. There are 4 remaining samples.
Please let me know if you wish for them to set those up.
Thank you,

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
N D - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
N C - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated
for the dilution using the most amount of sample.
B3 The dissolved oxygen depletion of the dilution water blank exceeded 0.2 mg/L.
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
H3 Sample was received or analysis requested beyond the recognized method holding time.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
R6 The RPD between valid sample dilutions exceeded 30%.

Summary of NPDES Monitoring: Post De -Icing Sampling 1/24/2022 - S&ME

February 23, 2022
Charlotte Douglas International Airport (CLT)
5601 Wilkinson Boulevard
Charlotte, North Carolina
Attention: Mr. Josh Eller
Reference:
Dear Mr. Eller:
[e-mail]
Summary of NPDES Monitoring: Post De -Icing Sampling 1/24/2022
Charlotte Douglas International Airport
5501 Josh Birmingham Parkway
Charlotte, North Carolina
S&ME Project No. 22350038B
S&ME, Inc. (S&ME) submits this Summary of National Pollution Discharge Elimination System (NPDES) Permit
required sampling, post -deicing activities conducted at the Charlotte Douglas International Airport (CLT). This
summary documents the field activities performed and presents the laboratory analytical data of selected outfalls
sampled around the perimeter of the CLT. The sampling services were performed in general accordance with the
Agreement for Professional Services between the City of Charlotte c/o Aviation Department and S&ME effective
April 26, 2019 ('The Agreement").
Project Background
Based on information provided to S&ME on January 13, 2022, we understand that CLT is required to perform
NPDES monitoring at Outfalls 002, 003, 004, F, H, and K as shown on the attached Sample Location Map Figure 2,
provided by CLT. Per NPDES wastewater and stormwater permit NC0083887, discharge monitoring sampling with
in -stream field parameter readings is required within 72 hours following de-icing activities of aircraft and surfaces
at CLT. CLT provided S&ME with a copy of NPDES permit NC0083887, the NCDEQ requested analytical
parameters list, and various maps of CLT showing outfall locations.
Summary of Sampling Activities
On January 24, 2022, S&ME personnel visited CLT and collected grab samples from outfalls 002, 003, 004, F, H,
and 1< for the following analysis*
• Propylene Glycol (milligrams per liter [mg/L])
• Ethylene Glycol (mg/L)
• Biochemical Oxygen Demand (mg/L)
• Chemical Oxygen Demand (mg/L)
• NH3 — Nitrogen (mg/L)
• pH (field reading) (Standard Units)
• Acute Toxicity (Ceriodaphnia dubia, 48 hour static test) (Pass/Fail)

Charlotte Douglas International Airport
5501 Josh Birmingham Parkway
Charlotte, North Carolina
S&ME Project No. 22350038B
Outfall samples were collected in laboratory provided sample containers labeled with site identification (location,
sample time, requested analysis, etc.), recorded on a laboratory provided Chain of Custody, and placed in a cooler
of ice
At each outfall location, concurrent with outfall sample collection, in -stream analytical monitoring of the receiving
stream was performed. Field readings for the following parameters were collected
• Dissolved Oxygen (mg/L)
• Turbidity (Nephelometnc Turbidity Unit [NTU])
• pH (Standard Units)
Field measurements and general observations were recorded and are included in the Attachments.
Collected samples were packaged in coolers of wet ice and transported by S&ME personnel under Chain of
Custody protocols to Pace Analytical Services - Charlotte (Pace) in Huntersville North Carolina on January 24,
2022. Bioassay analysis (acute toxicity) was performed by Pace subcontract laboratory ETT Environmental (ETT) in
Greer, South Carolina. The bioassay samples were transported by courier from Pace to ETT on January 25, 2022.

Discussion
24-hour static Acute Toxicity testing was performed by ETT rather than the discussed and requested 48-hour static
test. Pace notified S&ME of this discrepancy while providing the finalized laboratory results for the Acute Toxicity
laboratory testing. Pace indicated that the discrepancy occurred due to miscommunication between toxicity
laboratory personnel. A copy of the CDIA bioassay-9258456 email correspondence from Pace to S&ME, dated
February 16, 2022, is included in the attachments.

S&ME appreciates the opportunity to be of service to CLT. If you have any questions concerning this report,

Hi Brian,
Please see the attached report. The samples did pass.. however, ETT cut off the test at 24 hours instead of 48 hours. In
the email I received, it looks like this was due to miscommunication between the toxicity lab personnel. I did confirm
that the samples from 1/31 were set up correctly and run for 48 hours. Please let me know if you have any questions.
Thank you,
Angela

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
N D - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
N C - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated
for the dilution using the most amount of sample
D4 Sample was diluted due to the presence of high levels of target analytes.
R1 RPD value was outside control limits.

Summary of NPDES Monitoring: Post De -Icing Sampling 1/31/2022 - S&ME

March 2, 2022
Charlotte Douglas International Airport (CLT)
5601 Wilkinson Boulevard
Charlotte, North Carolina
Attention: Mr. Josh Eller
Reference:
Dear Mr. Eller:
[e-mail]
Summary of NPDES Monitoring: Post De -Icing Sampling 1/31/2022
Charlotte Douglas International Airport
5501 Josh Birmingham Parkway,
Charlotte, North Carolina
S&ME Project No. 22350038C
S&ME, Inc. (S&ME) submits this Summary of National Pollution Discharge Elimination System (NPDES) Permit
required sampling post -deicing activities conducted at the Charlotte Douglas International Airport (CLT). This
summary documents the field activities performed and presents the laboratory analytical data of selected outfalls
sampled around the perimeter of the CLT. The sampling services were performed in general accordance with the
Agreement for Professional Services between the City of Charlotte c/o Aviation Department and S&ME effective
April 26, 2019 ('the Agreement").
Project Background
Based on information provided to S&ME on January 13, 2022, we understand that CLT is required to perform
NPDES monitoring at Outfalls 002, 003, 004, F, H, and K as shown on the attached Sample Location Map Figure 2,
provided by CLT. Per NPDES wastewater and stormwater permit NC0083887, discharge monitoring sampling with
in -stream field parameter readings is required within 72 hours following de-icing activities of aircraft and surfaces
at CLT. CLT provided S&ME with a copy of NPDES permit NC0083887, the NCDEQ requested analytical
parameters list, and various maps of CLT showing outfall locations.
Summary of Sampling Activities
On January 31, 2022, S&ME personnel visited CLT and collected grab samples from outfalls 002, 003, 004, F, H,
and K for the following analysis*
• Propylene Glycol (milligrams per liter[mg/L])
• Ethylene Glycol (mg/L)
• Biochemical Oxygen Demand (mg/L)
• Chemical Oxygen Demand (mg/L)
• NH3 — Nitrogen (mg/L)
• pH (field reading) (Standard Units)
• Acute Toxicity (Ceriodaphnia dubia, 48-hour static test) (Pass/Fail)

Charlotte Douglas International Airport
5501 Josh Birmingham Parkway
Charlotte, North Carolina
S&ME Project No. 22350038C
Outfall samples were collected in laboratory provided sample containers labeled with site identification (location,
sample time, requested analysis, etc.), recorded on a laboratory provided Chain of Custody, and placed in a cooler
of ice.
At each outfall location, concurrent with outfall sample collection, in -stream analytical monitoring of the receiving
stream was performed. Field readings for the following parameters were collected
• Dissolved Oxygen (mg/L)
• Turbidity (Nephelometric Turbidity Units [NTU])
• pH (Standard Units)
Field measurements and general observations were recorded and are included in the Attachments
Collected samples were packaged in coolers of wet ice and transported by S&ME personnel under Chain of
Custody protocols to Pace Analytical Services - Charlotte (Pace) in Huntersville, North Carolina on January 31,
2022. Bioassay (acute toxicity) samples were transported by courier from Pace to ETT Environmental (ETT) in
Greer, South Carolina on February 1, 2022 for analysis.

S&ME Project No. 22350038C
Discussion
The 48-hr. static Acute Toxicity test was performed by ETT. Samples for Outfalls 003 and 004 were reported as Fail.
The pass or fail result is based on a statistical T test, which is determined by the percentage of mortality that
occurs during the test. Note: that Outfall 004 is the upstream sample location and is considered "Background".
Closure
S&ME appreciates the opportunity to be of service to CLT. If you have any questions concerning this report,

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
N D - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
N C - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4 5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
B1 Less than 1.0 mg/L DO remained for all dilutions set. The reported value is an estimated greater than value and is
calculated for the dilution using the least amount of sample.
B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated Tess than value and is calculated
for the dilution using the most amount of sample.
CL The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased
low.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
