Dear Covenant Transport:
Information received by this regional office of the Underground Storage Tank Section (UST Section),
Division of Waste Management, on January 18, 2023, 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 02L .0504 and, if applicable,
the assessment and reporting requirements of Title 15A NCAC 02L .0505, within the timeframes specified
in the attached rules. (Be aware that if Title 15A NCAC 02L .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 02L .0504 and the most recent version of the Guidelines for
Site Checks, Tank Closure, and Initial Response and Abatement, within 90 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).

15A NCAC 02L .0504 REQUIRED INITIAL RESPONSE AND ABATEMENT ACTIONS BY
RESPONSIBLE PARTY
Upon a discharge or release of petroleum from a non-UST petroleum source the responsible party shall:
(1)take actions to prevent all further discharge or release of petroleum from the non-UST petroleum
source; identify and mitigate all fire, explosion, or vapor hazard; and report the release within 24
hours of discovery, in compliance with G.S. 143-215.83(a), 84(a), and 85(b);
(2)perform initial abatement actions to measure for the presence of a release where contamination is
most likely to be present; confirm the source of the release; investigate to determine the possible
presence of free product; begin free product removal; and to continue to monitor and mitigate all
additional fire, explosion, or vapor hazards posed by vapors or by free product; and submit a
report to the Department of Environmental Quality, UST Section, Regional Office Supervisor in
accordance with 15A NCAC 02B .0309 and .0311, within 20 days after release confirmation
summarizing these initial abatement actions;
(3)remove contaminated soil that would act as a continuing source of contamination to groundwater.
For a new release, no further action shall be necessary if:
(a)initial abatement actions involving control and removal of contaminated materials are
initiated within 48 hours from discovery and before contaminated materials begin to
impact groundwater; and
(b)analysis, in accordance with the approved methods in Rule .0412 of this Subchapter, of
representative samples of remaining soils shows concentrations:
(i)at or below the more stringent of the soil-to-groundwater concentration value
and the residential maximum soil contamination concentration value; or
(ii)using other EPA-approved analytical methods in accordance with Rule
.0412(b)(7) of this Subchapter, concentration values below the more stringent of
the soil-to-groundwater concentration alkane and aromatic carbon fraction class
values and the residential maximum soil contamination concentration alkane and
aromatic carbon fraction class values;
For new releases, if the abatement actions cannot be initiated within 48 hours of discovery or if
soil concentrations remain above the values in this Paragraph, the responsible party shall conduct
all activities under Items (1) through (5) of this Rule;
(4)conduct initial site assessment, assembling information about the site and the nature of the release,
including the following:
(a)a site history and site characterization, including data on nature and estimated quantity of
release and data from available sources and site investigations concerning surrounding
populations, water quality, use, and approximate locations of wells, surface water bodies,
and subsurface structures potentially affected by the release, subsurface soil conditions,
locations of subsurface utilities, climatological conditions, and land use;
(b)the results of free product investigations and free product removal, if applicable;
(c) the results of groundwater and surface water investigations, if applicable;
(d) a summary of initial response and abatement actions; and
(5) submit as required in Item (2) of this Rule, within 90 days of the discovery of the discharge or
release:
(a) an initial assessment and abatement report as required in Item (4) of this Rule;
(b) soil assessment information sufficient to show that remaining unsaturated soil in the side
walls and at the base of the excavation does not contain contaminant levels that exceed
either the soil-to-groundwater or the residential maximum soil contaminant
concentrations established by the Department pursuant to Rule .0511 of this Section,
whichever is lower; and
(c) documentation to show that neither bedrock nor groundwater was encountered in the
excavation or, if groundwater was encountered, that contaminant concentrations in
groundwater were equal to or less than the groundwater quality standards established in
Rule .0202 of this Subchapter. If such showing is made, the discharge or release shall be
classified as low risk by the Department.
