Dear Mr. Pederson:
The Tank Closure Report received by the UST Section, Division of Waste Management, Mooresville
Regional Office on September 18, 2023 has been reviewed. The review indicates soil contamination
exceeds the lower of the residential or soil-to-groundwater MSCCs referenced in Title 15A NCAC 2L
.0511, and groundwater contamination exceeds the groundwater quality standards established in Title 15A
NCAC 2L .0202 Therefore, the UST Section hereby confirms that you must comply with assessment and
reporting requirements of Title 15A NCAC 02L .0505, within the timeframes specified in the attached rule.
The requirements of Title 15A NCAC 02L .0505 include the preparation and submittal of a Limited Site
Assessment (LSA) Report, in accordance with the rule and the most recent version of the UST Section
Assessment Guidelines, within 120 days of discovery of the release.
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 02L .0103(e) and 02L .0111(e).
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
("Notice") plat and declaration with the Register of Deeds in the county where the property is located
(NCGS 143B-279.9 and 143B-279.10).
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.
