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 July 7, 2020 Corrective Action Monitoring Reports on July 2, 2020. The report
recommending continued system deactivation and an additional groundwater monitoring events was
reviewed and approved on July 28, 2020. 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 June 2, 2020, Apex collected groundwater samples from twelve monitoring wells (MW-9,
MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25,
and DMW-3). Analytical results yielded petroleum compounds in five of the twelve
monitoring wells sampled, with a maximum MTBE concentration 42.3 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 and MW-23.
• 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 six supply wells (5922, 5925, 5927, 5955
Turkey Road and 2847 and 2865 Lane Street). Petroleum compounds have never been
detected in potable water supplies. Tetrachloroethene at a concentration of 1.10 µg/L was
detected in supply well SW-5922 (consistent with the previous sampling events). 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.
• Continue semi-annual groundwater sampling/monitoring.
• Install and sample two monitoring wells between the site and potable residential water supply
wells for the next sampling event.
• The next sampling event for the Monitoring Report shall be conducted in June 2021. No
Corrective Action Performance Report is required to be submitted when the treatment system
is off per NCDEQ directive. The next Monitoring Report is due no later than July 31, 2021.
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.
