Dear Click:
Information received by the Wilmington Regional Office of the UST Section, Division of Waste
Management, on December 9, 2022 indicates the potential for a suspected release, from the subject facility,
due to the discovery of offsite impacts, including the detection of petroleum compounds on offsite property
monitoring wells.
Records indicate that you are the owner or operator of a UST system suspected of being the source for this
release. Therefore, you must immediately investigate to confirm the suspected release pursuant to Title 15A
NCAC 02N .0603. To achieve compliance with this rule, you must:
1. conduct tank tightness tests for each UST in accordance with federal regulation 40 CFR
280.43(c) (as incorporated by Title 15A NCAC 02N .0504),

2. conduct line tightness tests for each piping system associated with a UST in accordance
with 40 CFR 280.44(b) (as incorporated by Title 15A NCAC 02N .0505), and
3. conduct a site check in accordance with 40 CFR 280.52(b) (as incorporated by Title 15A
NCAC 02N .0603) as described in the most recent version of the Guidelines for Site
Checks, Tank Closure, and Initial Response and Abatement Action, as available at
https://deq.nc.gov/about/divisions/waste-management/underground-storage-tanks-
section/ust-guidance-documents .

The results of the tank tightness test(s) and line tightness test(s) must be received by this office within 7
days of receipt of this notice. The results of the site check must be received by this office within 30 days of
receipt of this notice. If a release or discharge is 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 02L .0103(e) and 02L .0111(e).
Failure to comply in the manner and time specified may result in the assessment of civil penalties
and/or the use of other enforcement mechanisms.
Please note that, as the aforementioned site investigation efforts described above are being required by the
Department based upon a determination that this UST system represents a suspected source of an off-site
impact, and, in this case, are not routine leak detection procedures associated with an onsite detection of a
suspected release, some or all of the investigative costs may be eligible for reimbursement from the
Commercial Leaking Petroleum Underground Storage Tank Cleanup Fund (Trust Fund) reimbursement
under North Carolina General Statute (G.S.) 143-205.94B(b)(8). If you have any questions regarding Trust
Fund eligibility or reimbursement, please contact the UST Section Trust Fund Branch at [phone].
If you have any questions regarding the actions that must be taken or the rules mentioned in this letter,
please contact me at [phone] or the address listed below.
Sincerely,
Liz Price
Hydrogeologist
