FOR
FERRELLGAS TRUCK ACCIDENT (DIESEL FUEL RELEASE)
NEAR EXIT 100, HIGHWAY I-73
GREENSBORO, GUILFORD COUNTY, NORTH CAROLINA
ATC Associates of North Carolina, P.C. (ATC) has prepared the following report for Ferrellgas, LP (Ferrellgas)
on initial site assessment activities performed near Exit 100, Highway I-73 in Greensboro, Guilford County, North
Carolina in response to a release of diesel fuel and motor oil from a fuel transport truck as a result of a vehicle
accident. This report has been prepared pursuant to applicable sections of Title 15A of the North Carolina
Administrative Code (NCAC), Chapter 2, Subchapter 2L and in accordance with the State of North Carolina
Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Underground Storage
Tank (UST) Section Guidelines for Initial Response and Abatement, Assessment, and Corrective Action for
Non-UST Releases, effective July 1, 2012.
1.0 SITE HISTORY AND CHARACTERIZATION
1.1 OWNER AND RELEASE INFORMATION
On October 31, 2022, a Ferrellgas transport truck was exiting Highway I-73 on Exit 100 when the vehicle travelled
off the exit ramp. Due to the accident, an unknown amount of diesel fuel and motor oil were released onto the
rocks and soil off the shoulder of the exit ramp and into an unnamed intermittent tributary of Reddick’s Creek.
The approximate location of the spill area is provided on Figure 1.
Initial spill response activities were performed by others and information detailing the activities conducted are not
known at this time. It is known that absorbent booms were placed in the unnamed intermittent tributary of Reddick’s
Creek to contain the diesel fuel and motor oil. The exact amount of liquids that were recovered are not known at this
time.
1.2 SITE CHARACTERISTICS
1.2.1 Site Status
The spill area was located along the eastern side of Highway I-73 adjacent to Exit Ramp 100 in Greensboro,
Guilford County, North Carolina. The spill location occurred mainly in an area that consisted of rocks and soil.
An unnamed intermittent tributary of Reddick’s Creek was also impacted by the traffic accident.
1.2.2 Surrounding Property Use
According to Guilford County Geographic Information Systems (GIS), properties in proximity to the spill area
are mainly undeveloped or residential.
1.2.3 Site Geology/Hydrogeology
Based on observations made during soil excavation activities, the area of the spill was mainly rocks and silty
sand. As an intermittent stream is located in the spill area, groundwater was encountered at an approximate depth
of one to two feet below ground surface (bgs).
Initial Site Assessment Report ATC Associates of North Carolina, P.C.
Ferrellgas near Exit 100, Highway I-73 March 23, 2023

1.2.4 Limited Receptor Survey
ATC personnel researched the locations of private water supply wells within a 1,500-foot radius from the source
area on the Guilford County GIS website (https://gisdv.guilfordcountync.gov/guilford/). Private water supply
wells were identified at two residential properties located at 2902 Cromwell Road and 2904 Cromwell Road,
approximately 1,302 feet and 1,325 feet north of the source area, respectively. It should be noted these two water
supply wells should not be impacted by the diesel fuel release as they are located upgradient of the release area.
An unnamed intermittent tributary to Reddick’s Creek is located within the spill area. At the time of the spill and
during soil excavation activities, water was present within the unnamed stream. Reddick’s Creek, located
approximately 2,500 feet to the southwest of the spill area is identified as a Water Supply-IV stream with a stream
index of 17-8-(0.5). Reddick’s Creek has an average water hardness of 44 parts per million (ppm).
Subsurface structures were not identified at the site.
1.3 INITIAL RESPONSE AND ABATEMENT ACTIONS
1.3.1 Source Control Actions
Other than removal of the fuel transport truck and its remaining contents, it is reported that fuel and surface water
was removed from the area via vacuum truck. It is not known at the time of this report the quantity of liquids that
were recovered. Petroleum-impacted soil at the site was covered with plastic until soil excavation activities could
be conducted and absorbent boom was placed in the unnamed intermittent tributary to Reddick’s Creek to contain
any residual petroleum on the surface water.
1.3.2 Contaminant Migration Control Measures
During initial emergency response activities, it is reported that absorbent boom were placed in the unnamed
intermittent tributary to Reddick’s Creek to contain any residual petroleum on the surface water. Additionally,
plastic was used to cover the petroleum-impacted soil at the site until soil excavation activities could be conducted.
1.3.4 Measures to Identify and Mitigate Hazards
Subsequent to the initial response and contaminant control activities, plastic was placed over areas that were
visually observed to have been impacted by the fuel spill to prevent additional contaminant migration in the event
of precipitation.
1.3.5 Free Product Assessment and Removal
Light non-aqueous phase liquid (LNAPL) was not encountered during soil excavation activities.
2.0 SOIL EXCAVATION ACTIVITIES
On January 18, 2023, ATC contracted with Eastern Environmental Management, LLC (EEM) to assist with the
excavation of diesel fuel and motor oil impacted soil at the site of the spill.

The soil excavation measured approximately 15 feet in length, 8 feet in width, and varied between a few inches
to five feet in depth. The area of excavation is provided in Figure 2.
Excavated soils were placed directly into a dump truck and disposed of at AES of NC located in Thomasville,
North Carolina. Approximately 18.33 tons of petroleum-impacted soil were removed for proper off-site disposal.
The soil disposal manifest is provided in Appendix A.
It should be noted one soil sample (labelled SS-1) was collected for disposal purposes. The analytical results are
provided in Table 1. A copy of the laboratory report and chain-of-custody documents is provided in Appendix
B.
3.0 CONFIRMATORY SOIL SAMPLES
ATC personnel performed confirmatory soil sampling prior to backfilling the excavated area. Four soil samples
were collected from the sidewalls of the excavation (samples W-1 through W-4) approximately one to two feet
above the water line. The locations of the confirmatory soil samples are depicted on Figure 2.
All samples were collected in laboratory-supplied containers and shipped on ice to SGS North America, Inc. in
Scott, Louisiana. The four soil samples were analyzed by Environmental Protection Agency (EPA) Methods 8260
and 8270, EPA Method 6020 for chromium and lead, and Massachusetts Department of Environmental Protection
(MADEP) Methods for volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH).
Laboratory analytical results of soil samples W-1 through W-4 detected chromium concentrations above
established Residential and Industrial/Commercial Maximum Soil Contaminant Concentrations (MSCCs). It is
assumed that the detected chromium concentrations are from naturally occurring sources and not from the truck
accident. Petroleum-related impacts to soil were not identified above established Soil-to-Groundwater (STGW)
MSCCs. The analytical results are presented in Table 1. Petroleum-related impacts to soil are provided on Figure
2.A copy of the laboratory report and chain-of-custody documents is provided in Appendix B.
Due to the location of the spill being bound by the unnamed intermittent tributary to Reddick’s Creek and rock,
as much soil as possible was removed without compromising the stream integrity. At this time, it appears
petroleum-impacted soil has been effectively removed to below STGW-MSCCs.
Following completion of excavation activities, the excavated area was backfilled with clean rip-rap. Other areas
distributed during the soil excavation activities were restored using straw matting, grass seed, and covered with
additional straw.
4.0 SURFACE WATER SAMPLING
On January 30, 2023, ATC personnel visited the spill area to collect two surface water samples from the unnamed
intermittent tributary to Reddick’s Creek. The locations of the surface water samples (labelled SW-1 and SW-2)
are depicted on Figure 3. It should be noted surface water sample SW-2 was collected near the spill area and
surface water sample SW-1 was collected downstream.
The surface water samples were collected by hand, using the direct dip method. The surface water samples were
collected directly into laboratory-supplied containers and shipped on ice to SGS North America, Inc. in Scott,
Louisiana. The two surface water samples were analyzed by EPA Methods 6200B to include ethanol and

oxygenates, EPA Method 6020 for chromium and lead, and for EPA Method 625 plus ten highest non-target
peaks, and MADEP Methods for VPH and EPH.

Laboratory analytical results of the surface water sample collected from location SW-1 detected Total Polynuclear
Aromatic Hydrocarbons (PAH) concentrations above its established 2B x 10 Surface Water Standard. Laboratory
analytical results of the surface water sample collected from location SW-2 did not detect dissolved target
compound concentrations above established 2B x 10 Surface Water Standards. The analytical results are
presented in Table 2. Petroleum-related impacts to surface water are provided on Figure 3. A copy of the
laboratory report and chain-of-custody documents is provided in Appendix B.

It should be noted it is not known if the petroleum-related impacts identified at the downgradient surface water
sampling location are from the diesel fuel spill or from highway runoff. Petroleum-related impacts to surface
water were not identified at the sampling location adjacent to the spill area.

5.0 CONCLUSIONS AND RECOMMENDATIONS
5.1 CONCLUSIONS
Based on the information obtained during initial site assessment activities, the following conclusions are made:

• Diesel fuel and motor oil were released from a Ferrellgas truck during a vehicle accident.
• Per the Guilford County GIS website and google street view, two water supply wells were
identified within 1,500 feet of the source area. These two identified water supply wells are located
upgradient of the spill area and are not expected to become impacted.
• An unnamed intermittent tributary to Reddick’s Creek is within the spill area. Reddick’s Creek is
located approximately 2,500 feet southwest of the spill area.
• Diesel fuel and motor oil impacted the surface water feature and soil/rocks in the area of the
accident.
• Approximately 18.33 tons of soil impacted by diesel fuel and motor oil were excavated and
disposed of.
• LNAPL was not encountered during soil excavation activities.
• Four soil samples collected from the sidewalls of the excavation detected chromium concentrations
above established Residential and Industrial/Commercial MSCCs. It is assumed that the detected
chromium concentrations are from naturally occurring sources and not from the truck accident.
• Due to the location of the spill being bound by the unnamed intermittent tributary to Reddick’s
Creek and rock, as much soil as possible was removed without compromising the stream integrity.
At this time, it appears petroleum-impacted soil has been effectively removed to below
STGW-MSCCs.
• Laboratory analytical results of the surface water sample collected from location SW-1 detected
Total PAH concentrations above its established 2B x 10 Surface Water Standard. Laboratory
analytical results of the surface water sample collected from location SW-2 did not detect dissolved
target compound concentrations above established 2B x 10 Surface Water Standards. It is not
known if the petroleum-related impacts at the downgradient sampling location are from the diesel
fuel spill or from highway runoff. Petroleum-related impacts to surface water were not identified
at the sampling location adjacent to the spill area.

LABORATORIES CHAIN OF CUSTODY INSTRUCTIONSr the company name, address, phone number, and person designated to receive the analytical report Sampler's full name(s) and phone number needsbe enlered in case the laboralory discovers a sampling anomaly and needs to make a call. The nam€(s) will correspond with sampler's initials listed in thellection sectlon under sampled by.ill in all the requested information that is available. This information is critical to matching up specilic project and billing information in our LIMS to the jobsted on the chain. The slate of origin must be filled in to ensure that our reportang format meets the requirements of that specific state and to €nsure that weave certifications for that state.LEARLY, write in the sample lD, dates, times and samplers initials. All information must be legible. Use one line per sample point unless the sample wasen at multiple times for differenl t6sts- ln such a case use a separate line for the bottles taken at different times- Enter the date, and time ot each samplease note AM and PM or use Mjlitary time. Check this information and the Field lDs against the information recorded on the bottles. Mak6 sure allrmation matches exactlyitandad abbreviations for matrix codes are listed on th6 right side of the chain. DW- Orinking Water, Gw-Ground Water, WW- Water or Wastewatea, SW-iurface Water, SO- Soil, SL- Sludge, SED-Sediment, Ol- Oil, LIQ- Other Liquid, SOL- Other Solid, WP- Wipe, AIR- Air. FB- Field Blank. RB- Rinse Blank.B- Equipment BIank, TB- Trip Blank. Enter lh6 matrix code in the matrix column.
