Initial Assessment Report
Penn Tank Lines- Jet Fuel Release Incident
Page 2

B. Background and Initial Response Activities
On October 26, 2022, during filling operations of an underground storage tank (UST), a discharge line
from a fueling truck (operated by Penn Tank Lines) ruptured, releasing approximately 100 gallons of jet
fuel. The released product leaked onto the graveled-covered ground surface at an Air Wilmington remote
aircraft fueling facility. The aboveground release occurred near Building #1925, at 1817 Aviation Drive,
Wilmington International Airport, in Wilmington, New Hanover County, North Carolina. The approximate
location of the site is graphically presented on Figure 1 and Figure 2 (included in Appendix A) and is
situated at approximate coordinates 34.272407 N and -77.909702 W. A map of the area impacted is
included as Figure 3.

Penn Tank Lines contracted with A-C-T Environmental & Infrastructure , Inc. (A-C-T), who hired First Call
Environmental (FCE) to provide emergency response and soil remedial services. On October 27, 2022,
FCE contracted Highlands Environmental Solutions, Inc. (HES) to provide environmental oversight and
sampling services. A site-specific health and safety plan (HASP) was developed by HES for these site
activities. A copy of the HASP is included in Appendix B. FCE also contacted the North Carolina 811
service to locate and identify any potential underground utilities at the site.

C. Free Product Investigation and Recovery
On the day of the incident, representatives of Penn Tank Lines and/or the airport personnel deployed dry
granular absorbents to the impacted areas of gravel. The spent absorbents were placed into three 55-
gallon steel drums for disposal. During the soil excavation activities described below, the spent
absorbents were emptied into a roll off box for final disposal.

D. Groundwater and Surface Water Investigation
The released jet fuel did not migrate beyond the localized area of impact. The closest surface water body
is a perennial stream located approximately 640 feet North of the release location.

Groundwater was not encountered during remediation activities; therefore, a groundwater investigation
was not performed during site activities.

E. Initial Response and Abatement Activities.
Abatement activities included the application of dry absorbents as described in Section C.

F. Excavation of Petroleum Impacted Soil
On October 28, 2022, personnel from HES and FCE mobilized to the site and conducted soil excavation
activities. Select photographs of the site and remediation activities are included in Appendix C.

FCE utilized a track-mounted mini-excavator to excavate impacted soils. During excavation, HES utilized
field indicators (i.e., staining, and/or odor) and collected random soil samples from excavated areas to
field screen for organic vapors using a photoionization detector (PID – Mini Rae 3000). To field screen
the samples, an aliquot of soil was placed in a clean, labeled, zip-lock bag and allowed to volatilize for
approximately 10 minutes. At the end of the volatilization period, the sampling probe for the PID was
inserted into the bag to screen for the presence of organic vapors. Utilizing these techniques, HES
determined the estimated final limits of the horizontal extent of the excavation.

The resulting excavation measured approximately 38 feet in length, by various widths of 8.0 to 18.0 feet
in width, ranging from 0.5 to 1.5 feet in depth. Underground utilities were present in the area, which
limited the depth of the excavation. Following completion of the excavation, HES personnel collected six
post-excavation confirmation soil samples (“CS-1” thru “CS-6”) for laboratory analysis. A diagram
depicting the excavation and sample collection locations is included as Figure 4.

Upon collection, the post excavation soil samples were split into two aliquots. The first aliquot was placed
in a clean zip-lock bag and field screened for organic vapors using the previously described methodology.
For the second aliquot, a Terracore sampler was used to obtain a soil core for laboratory analysis. The

Initial Assessment Report
Penn Tank Lines- Jet Fuel Release Incident
Page 3

soil core was placed in a labelled, laboratory-supplied container, and hand delivered to RedLab, LLC in
Wilmington, North Carolina. The samples were analyzed for gasoline and diesel range organics (GRO
and DRO, respectively) using RedLab’s UVF technology, which is approved by the North Carolina
Department of Environmental Quality (NCDEQ).

At the completion of the soil excavation activities, approximately 13.96 tons of impacted soil and gravel
were placed into a roll off box. The waste soil was transported to J&R Farms, LLC, in Fair Bluff, NC for
disposal. J&R Farms, LLC is a permitted disposal facility for petroleum-impacted soil (i.e., land farm). A
copy of the waste disposal documentation is included in Appendix D.

Laboratory analysis of the soil samples resulted in the detection of GRO in each of the six samples at
concentrations ranging from 0.85 mg/kg to 485.1 mg/kg. GRO concentrations in samples CS-1, CS-3,
CS-5 and CS-6 exceeded the NCDEQ State Action Limit of 50 mg/kg. Laboratory analysis of the soil
samples resulted in the detection of DRO in each of the six samples at concentrations ranging from 11.1
mg/kg to 2,113 mg/kg. DRO concentrations in samples CS-1, CS-3, CS-5 and CS-6 exceeded the
NCDEQ State Action Limit of 100 mg/kg. Personnel from HES and RedLab reviewed the UVF
fingerprints for the post-excavation soil samples. The UVF fingerprints for samples CS-1, CS-5, and CS-6
indicated the presence of “fresh” petroleum (jet fuel), while the UVF fingerprints for samples CS-2, CS-3,
and CS-4 exhibited a “degraded” petroleum fingerprint.

A summary of the soil analytical data is presented in Table 1 and included as Appendix E. The complete
laboratory analytical data reports and chain-of-custody records for the samples are included as Appendix
F.

G. Conclusions and Recommendations
On October 26, 2022, during filling operations of an underground storage tank (UST), a discharge line
from a fueling truck (operated by Penn Tank Lines) ruptured, releasing approximately 100 gallons of jet
fuel. The released product leaked onto the graveled covered ground surface at an Air Wilmington remote
aircraft fueling facility. The aboveground release occurred near Building #1925, at 1817 Aviation Drive,
Wilmington International Airport, in Wilmington, New Hanover County, North Carolina.

On October 28, 2022, personnel from HES and FCE mobilized to the site and conducted soil excavation
activities. Soil excavation activities were limited due to the presence of underground utilities in the
subsurface. As a result of these activities, approximately 24 tons of impacted soil was placed into a roll
off box for future disposal.

Following completion of the excavation, HES personnel collected six post-excavation confirmation soil
samples (“CS-1” thru “CS-6”) for laboratory analytical testing purposes. Laboratory analysis of post
excavation confirmation soil samples resulted in the detection of residual GRO and DRO in all six
samples. Previous petroleum release incidents have been documented at the site. Evaluation of the
UVF fingerprints for the post-excavation soil samples indicate the presence of both “fresh” and
“degraded” petroleum in the samples. Fresh petroleum-related impacts at concentrations greater than
the State Action Limit were detected in three of the post-excavation soil samples. Degraded petroleum-
related impacts were detected in three of the post-excavation soil samples. Based on the analytical data,
HES concludes that degraded petroleum-related impacts detected at the site are not related to the
subject release incident that occurred on October 26, 2022. However, for the samples that exhibited
fresh UVF fingerprints, it is reasonable to conclude that these detections are reflective of residual
petroleum-related impacts from the subject release incident that occurred on October 26, 2022.

Based on the results of this investigation, HES concludes that petroleum-impacted soil with
concentrations greater than State Action Limits remains at the site. HES recommends the performance
of a Phase I Limited Site Assessment (LSA) be performed at the site. The scope of work for the LSA
should be modified to include additional soil assessment activities. The additional soil assessment
activities are recommended to (1) complete the delineation of petroleum-impacted soil at the site and (2)

differentiate between areas of residual petroleum impacted soil that are related to the subject release,
and those that are related to previously documented petroleum releases at the site.
