EXECUTIVE SUMMARY
Hatteras Landing Marina is a petroleum retail facility, restaurant, hotel and marina located at 58848
Marina Way in Hatteras, Dare County, North Carolina. The adjoining properties are residential and
commercial. Municipal water is available to the site and surrounding properties. One 10,000-gallon
gasoline and one 15,000-gallon diesel USTs were removed on March 1, 2022. Product piping and
dispensers from the docks were connected to the product piping from the new UST system.

Prior to the initiation of the UST closure activities, two Type II monitoring wells were installed at the site.
Ground water samples were collected from GMW-1 and GMW-2 on February 3, 2022, in order to
determine if the ground water in the vicinity of the former UST system had been impacted by a release.
No concentrations of requested method constituents that exceeded the MACs were reported in the
ground water samples collected from GMW-1 and GMW-2 on February 3, 2022. This pre-assessment was
required in pursuant of NCDEQ-DWR approval for discharge water from the proposed excavation.

During the March 2022 UST closure activities, ground water was encountered at approximately 3.5 feet
BGS. Therefore, UST closure samples were collected along the sidewalls of the UST basin and dispenser
islands. Please note, product piping soil samples were not collected during the UST closure due to being
inaccessible. With permission from DEQ personnel, a ground water sample was collected from MW-3 in
lieu of product piping soil samples. All UST closure samples were analyzed for TPH-GRO and TPH-DRO by
UVF. Concentrations of TPH-GRO and TPH-DRO less than the RALs were reported in all UST closure soil
samples.

On April 11, 2022, one Type II monitoring well (MW-3) was installed along the product piping. Monitoring
well MW-3 was gauged, purged and sampled. All reported contaminant concentrations were less than
the MACs. No free product was observed.

Please note, DEQ personnel deemed ground water samples collected from GMW-1 and GMW-2 on
February 3, 2022, suitable as UST closure ground water samples.

Based on the soil and ground water sampling results collected during UST closure activities, there is no
evidence of a petroleum release. No further assessment is warranted.

On February 3, 2022, GRI personnel collected soil samples (UST-1-3’ through UST-14-3’) along the side
walls of the UST basin. Two soil samples (DI-1-2’ and DI-2-2’) were collected in the vicinity of the dispenser
islands and one soil sample (SP-1) was collected from the soil stockpile. The collected soil samples were
submitted for mobile laboratory analyses of TPH-GRO and TPH-DRO using UVF technology.

On April 11, 2022, one Type II monitoring well (MW-3) was installed directly adjacent to the product
piping. A ground water sample was collected from MW-3 in lieu of product piping soil samples following
discussion with the NCDEQ incident manager because the product piping ran underneath the store
building and was inaccessible. The depth to water measured in MW-3 on April 11, 2022, was 4.39 feet
below the top of well casing. Well construction information is presented in Table 3. The location of MW-
3 is shown on Figure 2. The well construction record is included as Appendix E.

The product piping and dispenser islands were not removed during UST closure activities. They are being
used for the newly installed compartmentalized UST.

Please note, DEQ personnel deemed ground water samples collected from GMW-1 and GMW-2 on
February 3, 2022, suitable as UST closure ground water samples.

D. FREE PRODUCT INVESTIGATION AND RECOVERY REPORT
During the March 2022 UST closure, free product was not encountered.

E. GROUND WATER INVESTIGATION
A ground water sample was collected from MW-3 on April 11, 2022, and was submitted for analyses of
VOCs + oxygenates using EPA Method 6200B, semi-VOCs using EPA Method 625 + 10 highest tentatively
identified compounds, EDB using EPA Method 504.1, as well as MADEP Methods VPH and EPH.
F. INITIAL RESPONSE AND ABATEMENT ACTION
1. Initial Response Actions:
One 10,000-gallon gasoline and one 15,000-gallon diesel USTs were removed on March 1, 2022. Since
ground water was observed at approximately 3.5 feet BGS in the excavation basin, soil samples were
collected along the sidewalls of the UST basin. All soil removed to access the USTs was returned to the
excavation as backfill.
 Source Control Actions: One 15,000-gallon diesel and one 10,000-gallon gasoline USTs were removed
from the site on March 1, 2022.
 Contaminant Migration Control Measures: A release was not observed; therefore, contaminant
migration control measures were not necessary.
 Measures Taken to Mitigate Fire/Safety Hazards: Prior to closure, the Dare County fire marshal
approved MAPS’s tank inertion methods and closure procedures. There did not appear to be any
immediate fire or safety hazards present as a result of the release. Free product was not encountered
during closure activities.
 Measures Taken to Identify and Mitigate Pollution Hazards: A release was not observed; therefore,

contaminant migration control measures were not necessary.

G. EXCAVATION OF CONTAMINATED SOIL
1. Extent of Soil Contamination:
No soil contamination was observed during the March 2022 UST closure.

2. Excavation Process:
All excavated soil from the March 2022 UST closure was returned to the UST basin as backfill for the
newly installed UST.

3. Sampling Description:
All soil samples were collected using a hand auger by GRI personnel. The ground water sample was
collected from MW-3 by GRI personnel following NCDEQ sampling guidelines using a disposable bailer.
Samples were collected with clean, disposable nitrile gloves and immediately placed on ice for transport
to the laboratory.

H. SOIL AND GROUND WATER RESULTS

INSTRUCTIONS (READ THIS FIRST)
Complete and return a UST-3 form at least thirty (30) days prior to closure or change-in-service activities.
Completed UST closure or change-in-service site assessment reports, along with a copy of the UST-2A and/or 2B forms, should be submitted
to the appropriate Division of Waste Management (DWM) Regional Office within thirty (30) days following closure activities. The UST-2 form
should also be submitted to the Central Office in Raleigh so that the status of the tanks may be changed to permanently closed and your
tank fee account can be closed out. Note: Tank fees may be due for unregistered tanks.
UST closure and change-in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site
Checks, Tank Closure and Initial Response. The guidelines can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust.
Note: To close tanks in place you must obtain prior approval from the DWM Regional office located in the region where the facility is located.
You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the
tank(s) will be taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed
by a qualified company. Tanks disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment.
If your tanks are disposed of improperly, you could be held responsible for the cleanup of any environmental damage that occurs.

Technical Procedures
Calibration
The UFV Trilogy has standard calibrations stored for the following analysis:
 GRO
 DRO
 Total PAH
 Target PAH
 Heavy PAH
Prior to use, calibration standards are used to perform a 5-point verification on the factory stored
calibrations for GRO and DRO. The calibration standards used are as follows:
GRO
 0.5 ppm
 1 ppm
 3 ppm
 5 ppm
 10 ppm
DRO
 0.1 ppm
 0.5 ppm
 1 ppm
 3 ppm
 5 ppm
Operation
Sample Extraction
 5mg of soil are weighed into a clean extraction jar
 Methanol is added to the extraction jar to create a 2x or 4x dilution
o 2x Dilution: 10 mL of methanol
o 4x Dilution: 20 mL of methanol
 The extraction jar is shaken for several minutes to thoroughly mix the soil with solvent
(methanol)
 The mixture is allowed to settle for several minutes
 A clean syringe is used to draw liquid from the extraction jar
 A clean filter is attached to the end of the syringe and the liquid dispensed through the filter
into a clean test tube
 This liquid is referred to as the extraction
Dilution Preparation
 An adjustable micropipette is used to precisely measure out the amount of extract needed for
the dilution
 The measured out amount of the extract is added to a clean test tube and methanol is added
dilute the extract. Examples of dilutions are shown below:

Extract Amount
500 μL

Technical Procedures
Sample Analyzation
 The dilution is shaken to thoroughly mix, then poured into a clean glass cuvette
 The desired module is inserted into the UVF Trilogy and the corresponding factory calibration is
selected
 “Measure Fluorescence” is pressed on the touchscreen and the reading is recorded
 The reading should be between the concentrations of the calibration standards (GRO: 0.5-10
ppm; DRO 0.1-5 ppm)
o Reading below the calibration standard range are recorded as below the detection limit
 Detection Limit = (lower range of calibration standards range) x dilution factor
(i.e. a GRO sample with a 100x dilution factor has a detection limit of 50 ppm)
o Readings above the calibration standard range should be further diluted and reanalyzed
o Negative readings are an indication of quenching (see below)
 The reading is multiplied by the dilution factor to calculate the final concentration
 Check suspected contaminated samples for quenching by running additional dilutions
o According to the siteLAB Quick Reference Guide:
“Quenching” can occur when the detector is swamped by too many hydrocarbons or
organic interferences, producing low or negative concentrations. Test the sample at
multiple dilutions to confirm results are linear and accurate.”
QA/QC
Method Blank
 A method blank of methanol will be analyzed following calibration and following the last sample
analyzed each day
Duplicates
 One duplicate will be analyzed for every 20 samples
 The duplicate will be prepared from the extract of the sample and diluted to the same factor as
the sample analyzed
