NC DEQ UST Section Incident #18989
H&H Job No. CDA-044
Dear Mr. Pitner and Mr. Bell:
On behalf of Charlotte Douglas International Airport (CLT), Hart & Hickman, PC (H&H) is
providing results of recent surface water sampling activities conducted in association with the jet
fuel release from the aboveground storage tank (AST) system at the CLT Wilson Air Center
General Aviation Fuel Farm located at 5414 Airport Drive in Charlotte (hereafter referred to as the
Site). The North Carolina Department of Environmental Quality (DEQ), Division of Waste
Management (DWM), Underground Storage Tank (UST) Section incident identification number
for the Site is #18989. A Site location map is included as Figure 1, and a Site map is included as
Figure 2.
CLT personnel observed evidence of petroleum seepage from the bank of an unnamed tributary of
Taggart Creek on property owned by the City of Charlotte at CLT on September 17, 2019. Since
that time, initial emergency response actions, absorbent boom and pad maintenance, and several

phases of assessment and petroleum free product or light non -aqueous phase liquid (LNAPL)
removal activities have been conducted by or on behalf of CLT.
On April 1, 2021, as an interim measure, while additional assessment and preliminary LNAPL
removal activities were being conducted, H&H submitted a BIOREM-2000 Oil Digester
Application Request to DEQ's UST Section and members of DEQ's Division of Water Resources
(DWR) to obtain agency concurrence for the use of BIOREM-2000 Oil Digestorrm (BIOREM) to
treat various surfaces (i.e., stream banks, vegetation, water surfaces, etc.) affected by the jet fuel
release. On May 12, 2021, DEQ's DWR conditionally approved the application of BIOREM to
treat various surfaces affected by the release contingent upon application of the product in
accordance with the manufacturer's instructions and below a dosage rate of 8.8 milligrams per
liter (mg/L). DEQ DWR also required the implementation of a quarterly stream sampling schedule
for the unnamed tributary of Taggart Creek.
In accordance with DEQ's DWR request, H&H initiated quarterly surface water sampling
activities in the unnamed tributary of Taggart Creek in May 2021. The baseline surface water
sampling event was conducted on May 21, 2021, followed by application of BIOREM to treat
various affected surfaces on June 4, 2021, and post -application surface water sampling on
June 7, 2021. The results of the May 2021 baseline surface water sampling event and June 2021
post -application surface water sampling event were provided to DEQ's DWR and UST Section in
H&H's Surface Water Sampling Results letter report dated June 30, 2021. Since that time,
BIOREM has been directly applied to oily surfaces including stream banks, vegetation, and surface
waters typically once a week with a hand sprayer in accordance with the manufacturer's
instructions and below a dosage rate of 8.8 mg/L. Vegetation is currently present on the banks in
the vicinity of the former petroleum seeps where it was previously sparse.
In March 2022, H&H requested that the quarterly surface water monitoring schedule be reduced
to a semi-annual frequency based on the lack of target compounds above applicable standards or
screening values in the downstream portion of the unnamed tributary during the previous four

monitoring events. Furthermore, based on the lack of detection of RCRA metals above applicable
standards or screening values in the unnamed tributary of Taggart Creek during the previous four
monitoring events, H&H requested that Resource Conservation Recovery Act (RCRA) metals
analysis be eliminated from the surface water sampling program during future monitoring events.
On April 1, 2022, DEQ's DWR agreed that metals sampling could be discontinued from the
surface water sampling program but indicated that quarterly surface water monitoring must be
continued due to petroleum sheens observed in the unnamed tributary of Taggart Creek in
February 2022. Although it appears that the BIOREM has been effective in treating oily surfaces
on vegetation and stream banks, LNAPL continues to be observed occasionally in the unnamed
tributary of Taggart Creek and on water below the stormwater outfall situated south of Ashley
Circle. The results of the recent quarterly surface water sampling activities conducted on
September 7, 2023 are discussed below.
The September 2023 surface water sampling event was conducted during apparent base flow
conditions and included the collection and analysis of upstream and downstream surface water
samples. The location of the surface water samples (denoted by "SW" nomenclature) are depicted
in Figure 3. These samples were collected in the following locations:
• Upstream portion of the unnamed tributary of Taggart Creek above the BIOREM
application areas (SW -Upstream); and
• Downstream portion of the unnamed tributary of Taggart Creek below the BIOREM
application areas (SW -Downstream).
The surface water samples were collected in a downstream to upstream order during the sampling
event. Surface water samples were collected by lowering laboratory -supplied sample containers
into the center portion of the stream with the containers facing upstream and without disturbing
sediments. Surface water samples were labeled with the sample identification, date, and requested
analysis; and placed in a laboratory -supplied cooler with ice. The surface water samples were
delivered to Pace Analytical Services, LLC of Huntersville, North Carolina under standard chain

of custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260,
semi -volatile organic compounds (SVOCs) by EPA Method 8270, and extractable petroleum
hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH) by the Massachusetts
Department of Environmental Protection (MADEP) Methods.
The September 2023 and historical surface water sampling results are summarized in Table 1.
Copies of the laboratory analytical report and chain of custody record for the September 2023
sampling event are provided in Attachment A.
Taggart Creek is classified as a Class C surface water body (i.e., waters protected for uses such as
secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation,
survival and maintenance of biological integrity, and agriculture). Therefore, surface water sample
results were compared to the most stringent of the freshwater and human health 15A NCAC 02B
Surface Water Quality Standards (213 Standards) amended September 1, 2022 for a Class C surface
water body. In instances where a compound had no established 2B Standard, the surface water
sample results were compared to the EPA Nationally Recommended Water Quality Criteria
(NRWQC) screening values dated July 2016. In instances where a compound had no established
2B Standard or EPA NRWQC screening value, the surface water sample results were compared to
North Carolina In -Stream target values for surface waters dated July 2016.
No compounds were detected above the laboratory method detection limit in the SW -Upstream
and SW -Downstream samples.
H&H submitted a Free Product Corrective Action Plan (CAP) and remedial design to DEQ on
October 11, 2021. The Free Product CAP proposed dual phase extraction (DPE) as a dedicated
system to remove the free product. DEQ approved the October 11, 2021 Free Product CAP in a
letter dated December 1, 2021. The proposed DPE recovery wells were installed at the Site in
June 2022. DEQ approved the National Pollutant Discharge Elimination System General Permit
for the dedicated DPE system at the end of July 2022. DPE system fabrication work began in

April 2022, and field construction activities began in July 2022. The DPE system equipment was
delivered to the Site on October 26, 2022 and field construction activities were completed in late
December 2022. Following the establishment of electric services at the Site by Duke Energy in
mid -January, DPE system startup was conducted between January 23 and 25, 2023. Since that
time, as of the writing of this letter, the DPE systems have operated at the Site for approximately
162 days. Details of DPE system installation and performance, including NPDES effluent
sampling and LNAPL recovery are being provided to DEQ under separate cover. Initial results
indicate generally decreasing thicknesses over time and a general absence of LNAPL in monitoring
wells near the creek as a result of the DPE systems.

Notes:
(1) North Carolina Department of Environmental Quality (DEQ) NC 15A NCAC 02B Water Quality Standards for Surface Waters (213 Standard) (amended September 1, 2022)
(2) National Recommended Water Quality Criteria values are based on the values reported on EPA's Nationally Recommended Water Quality Criteria website as of July 22, 2016
(3) NC In -Stream Target Values for Surface Waters are based on values presented in North Carolina Division of Water Resources Surface Water Quality Standards, Criteria & In -Stream Target Values spreadsheet dated July 2016
(4) Standard listed is the fish consumption standard; commonly referred to as "Human Health" standards
*Sample SW-1 contained a mixture of LNAPL and surface water, collected in a side pool of the unnamed tributary immediately adjacent to the seep. Sample is not considered to be representative of the broader surface water system in that area.
+ = Acute & chronic values for metals on the NC 02B Standards table are based on the following language in 15A NCAC 02B .0211: Acute = "Compliance with acute instream metals standards shall only be evaluated using an average of two or more samples collected within one hour. "
Chronic = "Compliance with chronic instream metals standards shall only be evaluated using averages of a minimum of four samples taken on consecutive days, or as a 96-hour average."
= Value calculated using the North Carolina DEQ 2B Standards for Surface Waters "Hardness -Dependent Metal Calculations" based on the median water hardness value of 156,200 micrograms per liter (pg/L) from site -specific samples collected in May, June, September, and December
2021 and March 2022
With the exception of extractable petroleum hydrocarbons (EPH) and volatile petroleum compounds (VPH), only compounds detected in at least one sample shown above
Laboratory analytical methods are shown in parentheses
Underline value indicates compound detected above EPA National Recommended Water Quality Criteria for Aquatic Life & Human Health
Highlighted value indicates compound detected above NC In -Stream Target Values for Surface Waters
Tributary is a Class C Water
LNAPL = Light non -aqueous phase liquid; VOCs = Volatile organic compounds; SVOCs = Semi -volatile organic compounds; RCRA = Resource Conservation RecoveryAct; MADEP = Massachusetts Department of Environmental Protection
IAA = Initial Action Abatement; CAP = Corrective Action Plan
Samples collected in September and November 2019 were collected by Wood Environmental & Infrastructure Solutions, Inc. and were analyzed for 602 VOCs by EPA Method 6200, SVOCs by EPA Method 625, EPH and VPH by the MADEP Methods, and RCRA metals by EPA Method
6010 and 7471 (mercury only)
Samples collected in 2021, 2022, and 2023 were collected by H&H and were analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, EPH and VPH by the MADEP Methods, and RCRA metals by EPA Methods 6020 and 7470 (mercury only)
-- = Not available; NE = Not established; NS = Not sampled
J = Estimated concentration above the method detection limit and below the reporting limit
Because J flags were requested, less than concentrations are reported to the laboratory method detection limit
B = Analyte detected in blank; M = Minimum value due to potential for a low bias

QUALIFIERS
Project: CDA-044
Pace Project No.: 92686740
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - 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
NC - 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.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
SO Surrogate recovery outside laboratory control limits.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.

Case Narrative
The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation
or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.
Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all
NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter
(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list
for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified
Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target
Compound List, even if only a subset of the TCL are being reported. If a sample was re -analyzed or re -extracted due to a required quality
control corrective action and if both sets of data are reported, the Laboratory ID of the re -analysis or re -extraction is designated with an "R"
or "RE", respectively.
When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in
the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed
Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria
for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the
specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC
information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in
conjunction with the sample result, associated regulatory criteria and any associated data usability implications.
Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms
used in this report are provided in the Glossary located at the back of the report.
HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21
calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put
on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air
canisters will be disposed after 3 business days from the date the project is completed.
Please contact Project Management at 800-624-9220 with any questions.
I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and
belief and based upon my personal inquiry of those responsible for providing the information contained
in this analytical report, such information is accurate and complete. This certificate of analysis is not
complete unless this page accompanies any and all pages of this report.

from dilutions, concentrations or moisture content, where applicable. (DoD report formats only.)
EDL Estimated Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated
values, when those target analyte concentrations are quantified below the reporting limit (RL). The EDL includes any
adjustments from dilutions, concentrations or moisture content, where applicable. The use of EDLs is specific to the analysis
of PAHs using Solid -Phase Microextraction (SPME).
EMPC Estimated Maximum Possible Concentration: The concentration that results from the signal present at the retention time of an
analyte when the ions meet all of the identification criteria except the ion abundance ratio criteria. An EMPC is a worst -case

Analytical Method: Both the document from which the method originates and the analytical reference method. (Example: EPA 8260B is
shown as 1,8260B.) The codes for the reference method documents are provided in the References section of the Addendum.
Chlordane: The target compound Chlordane (CAS No. 57-74-9) is reported for GC ECD analyses. Per EPA,this compound "refers to a
mixture of chlordane isomers, other chlorinated hydrocarbons and numerous other components." (Reference: USEPA Toxicological Review
of Chlordane, In Support of Summary Information on the Integrated Risk Information System (IRIS), December 1997.)
Difference: With respect to Total Oxidizable Precursor (TOP) Assay analysis, the difference is defined as the Post -Treatment value minus the
Pre -Treatment value.
Final pH: As it pertains to Sample Receipt & Container Information section of the report, Final pH reflects pH of container determined after
adjustment at the laboratory, if applicable. If no adjustment required, value reflects Initial pH.
Frozen Date/Time: With respect to Volatile Organics in soil, Frozen Date/Time reflects the date/time at which associated Reagent Water -
preserved vials were initially frozen. Note: If frozen date/time is beyond 48 hours from sample collection, value will be reflected in'bold'.
Gasoline Range Organics (GRO): Gasoline Range Organics (GRO) results include all chromatographic peaks eluting from Methyl tert butyl
ether through Naphthalene, with the exception of GRO analysis in support of State of Ohio programs, which includes all chromatographic
peaks eluting from Hexane through Dodecane.
Initial pH: As it pertains to Sample Receipt & Container Information section of the report, Initial pH reflects pH of container determined upon
receipt, if applicable.
PAH Total: With respect to Alkylated PAH analyses, the 'PAHs, Total' result is defined as the summation of results for all or a subset of the
following compounds: Naphthalene, C1-C4 Naphthalenes, 2-Methylnaphthalene, 1-Methylnaphthalene, Biphenyl, Acenaphthylene,
Acenaphthene, Fluorene, C1-C3 Fluorenes, Phenanthrene, C1-C4 Phenanthrencs/Anthracenes, Anthracene, Fluoranthene, Pyrene, C1-C4

Benzo(a)pyrene, Perylene, Indeno(1,2,3-cd)pyrene, Dibenz(ah)+(ac)anthracene, Benzo(g,h,i)perylene. If a'Total' result is requested, the
results of its individual components will also be reported.
PFAS Total: With respect to PFAS analyses, the 'PFAS, Total (5)' result is defined as the summation of results for: PFHpA, PFHxS, PFOA,
PFNA and PFOS. In addition, the 'PFAS, Total (6)' result is defined as the summation of results for: PFHpA, PFHxS, PFOA, PFNA, PFDA
and PFOS. For MassDEP DW compliance analysis only, the'PFAS, Total (6)' result is defined as the summation of results at or above the
RL. Note: If a'Total' result is requested, the results of its individual components will also be reported.
Total: With respect to Organic analyses, a'Total' result is defined as the summation of results for individual isomers or Aroclors. If a'Total'
result is requested, the results of its individual components will also be reported. This is applicable to 'Total' results for methods 8260, 8081
and 8082.
Data Qualifiers
A Spectra identified as "Aldol Condensates" are byproducts of the extraction/concentration procedures when acetone is introduced in
the process.
B The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that
have detectable concentrations of the analyte at less than ten times (1 Ox) the concentration found in the blank. For MCP -related
projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x)
the concentration found in the blank. For DOD -related projects, flag only applies to associated field samples that have detectable
concentrations of the analyte at less than ten times (10x) the concentration found in the blank AND the analyte was detected above
one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ -
Air -related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the
reporting limit. For NJ -related projects (excluding Air), flag only applies to associated field samples that have detectable
concentrations of the analyte, which was detected above the reporting limit in the associated method blank or above five times the
reporting limit for common lab contaminants (Phthalates, Acetone, Methylene Chloride, 2-Butanone).
C Co -elution: The target analyte co -elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co -extracted
analyses.
D Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations
of the analyte.
E Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument.
F The ratio of quantifier ion response to qualifier ion response falls outside of the laboratory criteria. Results are considered to be an
estimated maximum concentration.
G The concentration may be biased high due to matrix interferences (i.e, co -elution) with non -target compound(s). The result should
be considered estimated.
H The analysis of pH was performed beyond the regulatory -required holding time of 15 minutes from the time of sample collection.
i The lower value for the two columns has been reported due to obvious interference.
J Estimated value. This represents an estimated concentration for Tentatively Identified Compounds (TICs).
M Reporting Limit (RL) exceeds the MCP CAM Reporting Limit for this analyte.
