EXECUTIVE SUMMARY
The Eagles 5 site is located at 620 Hampton Pointe Boulevard in Hillsborough, Orange County, North
Carolina. The property operates as a petroleum retail facility and convenience store. The site is covered
by concrete, asphalt and grass. There are one 20,000-gallon gasoline and one 20,000-gallon
compartmentalized (10,000-gallon gasoline and 10,000-gallon diesel compartments) USTs currently in use
at the site with six associated dispenser islands.

On December 5, 2022, GRI conducted a site check in the area of the 10,000-gallon diesel UST compartment
spill bucket. One soil sample (SS-1) was collected while spill bucket repairs were being made and
submitted for UVF analyses of TPH-GRO and TPH-DRO using UVF technology. All of the reported
contaminant concentrations were less than the applicable standards.

Based on this information, no additional assessment is warranted for this site.

A. SITE HISTORY AND CHARACTERIZATION
1. UST Owner and Operator Information:
In accordance with the Site Check Report guidelines, the UST owner and operator information has been
summarized in the attached Table 1.

2. UST System Information:
In accordance with the Site Check Report guidelines, the UST system information has been summarized
in the attached Table 2. There are one 20,000-gallon gasoline and one 20,000-gallon
compartmentalized (10,000-gallon gasoline and 10,000-gallon diesel compartments) USTs currently in
use at the site with six associated dispenser islands. A copy of the NCDEQ Registered Tank Report is
shown below:

3. Non-UST Information:
There are currently no ASTs at the site.

4. Comprehensive Description of the Release:
A defective spill bucket associated with the 10,000-gallon diesel UST compartment was observed and a
site check was required according to NCDEQ.

On December 5, 2022, soil sample (SS-1) was collected beneath the spill bucket associated with 10,000-
gallon diesel UST compartment while repairs were being completed. All reported contaminant
concentrations were less than the applicable standards.

5. Description of the Site Characteristics:
The Eagles 5 site is located at 620 Hampton Pointe Boulevard in Hillsborough, Orange County, North
Carolina. (Figure 1). The property operates as a petroleum retail facility and convenience store. The site
is covered by concrete, asphalt and grass. There are one 20,000-gallon gasoline and one 20,000-gallon
compartmentalized (10,000-gallon gasoline and 10,000-gallon diesel compartments) USTs currently in use
at the site with six associated dispenser islands. The surrounding properties are commercial. A Site Map

Clean, disposable nitrile gloves were used for the collection of the soil sample. The sample was collected
and transferred for UVF analysis following proper chain-of-custody procedures.

D. SUMMARY AND CONCLUSIONS
 The site is commercial and surrounding properties are commercial.
 On December 5, 2022, the spill bucket associated with the 10,000-gallon diesel UST compartment
received passing test results.
 A Site Check was conducted on December 5, 2022, to determine if a petroleum release had
occurred.
 One soil sample (SS-1) was collected approximately 3 feet BGS beneath the spill bucket as repairs
were being completed. All of the reported contaminant concentrations were less than the
applicable standards.
 Based on this information, no additional assessment is warranted for this site.
E. LIMITATIONS
This report has been prepared for the exclusive use of Guardian Fueling Technologies for the specific
application to the referenced site in Orange County, North Carolina. The assessment was conducted
based on the scope of work and level of effort specified by NCDEQ and with resources adequate only for
that scope of work. Our findings have been developed in accordance with generally accepted standards
of geology and hydrogeology practices in the State of North Carolina, available information, and our
professional judgment. No other warranty is expressed or implied.

The data that are presented in this report are indicative of conditions that existed at the precise locations
sampled and at the time the samples were collected. In addition, the data obtained from samples would
be interpreted as being meaningful with respect to parameters indicated in the laboratory report. No
additional information can logically be inferred from these data.

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:

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
