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 DigestorTM (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 the 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.
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. The results of the recent quarterly surface water sampling activities conducted on
June 7, 2022 are discussed below.
The June 2022 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
locations 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 Waypoint Analytical, LLC of Charlotte, 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 June 2022 and historical surface water sampling results are summarized in Table 1. Copies of
the laboratory analytical report and chain of custody record for the June 2022 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 (2B Standards) dated July 26, 2021 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.
The only compound detected in the surface water samples was trichloroethene (TCE) in the
upgradient sample. TCE is not a constituent in jet fuel, and the sampling location is upgradient of
the jet fuel release area. In addition, the detected TCE concentration (estimated 0.209 J micrograms
per liter, µg/L) does not exceed its 2B Standard of 30 µg/L.
If you have questions regarding these results or need additional information, please do not hesitate
to contact me at [phone].

Notes:
(1) North Carolina Department of Environmental Quality (DEQ) NC 15A NCAC 02B Water Quality Standards for Surface Waters (2B Standard) (July 26, 2021)
(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 Recovery Act; 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 and 2022 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
