Incident: 95827
Risk Classification: High
Information received by this regional office of the Underground Storage Tank Section (UST Section), Division of
Waste Management, on August 14, 2020, confirms a release or discharge of petroleum at the above -referenced
location. Furthermore, this office has determined that you are the responsible party for the assessment and cleanup of
the release or discharge.
As the responsible party, you must comply with the initial response and abatement action requirements of the Title
15A of the North Carolina Administrative Code (NCAC), Subchapter 2L .0504 and, if applicable, the assessment and
reporting requirements of Title 15A NCAC 2L .0505, within the timeframes specified in the attached rules. (Be aware
that if Title 15A NCAC 2L .0505 is applicable, you must comply with its requirements even if you do not receive
formal notification from the UST Section.)
Initial abatement action requirements include the preparation and submittal of an Initial Assessment Report (IAR), in
accordance with Title 15A NCAC 2L .0504 and the most recent version of the Guidelines for Site Checks, Tank
Closure, and Initial Response and Abatement for Non -UST Petroleum Releases, within 90 days of discovery of the

In order to facilitate free phase product removal at the source of the release, the UST Section requires
that prior to finalization of the repair of the affected portion of the pipeline and subsequent backfill of
the area, that recovery points be established as close to the pipeline/source as possible. Casings should
be set from the base of the excavation to the ground surface, to allow safe access for the drilling of
recovery wells.
Also, co -incident with finalization of repairs, the UST Section advises the construction of an interceptor
trench with multiple extraction points downgradient of the release source area to facilitate removal of
free phase product and petroleum -impacted groundwater and limit contaminant migration.
Because a release or discharge has been confirmed, a Licensed Geologist or a Professional Engineer, certified by the
State of North Carolina, is required to prepare and certify all reports submitted to the Department of Environmental
Quality in accordance with Title 15A NCAC 2L .0103(e) and 2L .0111(b).
Please note that before you sell, transfer, or request a "No Further Action" determination for a property that has not
been remediated to below "unrestricted use" standards, you must file a Notice of Contaminated Site or Notice of
Residual Petroleum with the Register of Deeds in the county where the property is located (North Carolina General
Statutes 143B-279.9, and 143B-279.10 or 143B-279.11).
Failure to comply with the State's rules in the manner and time specified may result in the assessment of civil penalties
and/or the use of other enforcement mechanisms.
If you have any questions regarding the actions that must be taken or the rules mentioned in this letter, please contact
me at the address or telephone number listed below.
