Risk -based Assessment and Corrective Action
for Petroleum Underground Storage Tanks
Pilot Travel Center #056
2825 Lane Street, Kannapolis
Cabarrus County
Incident Number: 36096
Risk Classification: High
The UST Section, Division of Waste Management (DWM), Mooresville Regional Office
(MRO) received the May 28, 2021 Corrective Action Monitoring Reports on May 28, 2021. The
report recommending continued system deactivation and an additional groundwater monitoring event
was reviewed and approved. The electronic copy has been loaded to the DWM's electronic
document storage system (Laserfiche).
The report states:
• Site remediation was performed via the soil vapor extraction and air sparge systems activated
on April 18, 2012 (shut down in August 2019).
• On May 12, 2021, Apex collected groundwater samples from fourteen monitoring wells
(MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24,
MW-25, MW-2, MW-28 and DMW-3). Analytical results yielded petroleum compounds in
six of the fourteen monitoring wells sampled, with a maximum MTBE concentration 36.8
µg/L in monitoring well MW-14. Benzene was not detected in any monitoring wells above
the laboratory method detection limit during this phase. The dissolved -phase endpoint for
MTBE of 20 µg/L was exceeded in monitoring wells MW-14.
• Free product was not detected in any groundwater monitoring wells gauged during this phase.

• Groundwater flow direction beneath the site is influenced by water table depression and
mounding created by system operation at the recovery/sparge wells. Historical groundwater
flow direction has been measured to the north-northwest.
• Apex also collected groundwater samples from five of six supply wells (5922, 5925, 5927,
5955 Turkey Road and 2847 Lane Street). A sample was not collected during this phase
from 2865 Lane Street as no one was home at the time of the site visit and there was no
outside access to potable water. Petroleum compounds have never been detected in potable
water supplies. Tetrachloroethene at a concentration of 1.89 µg/L was detected in supply
well SW-5922 (consistent with the previous sampling events). Tetrachloroethene is typically
associated with the use of solvents and could be the result of some recent plumbing repairs at
the residence.
• Sentinel wells MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is
confined to the original source zone identified and described in both the CSA and approved
CAP.
• Mass balance calculations of remaining benzene and MTBE at the site show approximately
30 grams of combined MTBE and benzene remain onsite as a result of the incident. A mass
reduction for MTBE and benzene of 99.95% has been accomplished with the remediation
system.
Per this Notice of Regulatory Requirements:
• The remediation system shall remain off. The system must be properly maintained and the
switch ready in case future use is necessary.
• The next sampling event for the Monitoring Report shall be conducted in June 2022. The
next Monitoring Report is due no later than July 31, 2022.
Please note that sampling and correction action must be conducted in accordance with the
Guidelines for Assessment and Corrective Action for UST Releases. Failure to comply in the
manner and time specified may result in the assessment of civil penalties and/or the use of the other
enforcement mechanisms.
If you have any questions regarding trust fund eligibility or reimbursement from the
Commercial or Noncommercial Leaking Petroleum Underground Storage Tank Cleanup Funds,
