EXECUTIVE SUMMARY
Precision Tune Auto Care was formally a vehicle repair, lube and maintenance facility. The site is located
at 3104 Raeford Road in Fayetteville, Cumberland County, North Carolina. The adjoining properties are
commercial. Municipal water is available to the site and surrounding properties.

On February 27, 2023, the building located on the site was demolished. The concrete capping the site
was also removed between February 27 and March 7, 2023.

On March 1, 2023, one oil-water separator was removed from the site.

On March 1, 2023, contaminated soil beneath a former hydraulic lift cylinder was excavated until visual
contamination was removed and DRO values were less than the RALs.

During the February and March 2023 abatement activities, ground water was not encountered.
Therefore, a soil sample was collected from beneath the oil-water separator and submitted for analyses
of TPH-GRO and TPH-DRO using a mobile UVF laboratory and for laboratory analyses of VOCs using EPA
Method 8260, SVOCs using EPA Method 8270, MADEP Methods VPH and EPH, and TCLP metals. Based
on the field observations, no over-excavation activities were conducted in the vicinity of the former oil-
water separator. Concentrations of chromium that exceeded the residential SCL were reported in the soil
samples collected from CS-1-7’ and BG-1-8’. BG-1-8’ was collected from an area isolated from any
suspected contamination and used as a background soil sample for the site. Based on this information,
chromium is likely naturally occurring at the site and is not the result of petroleum contamination.

On March 1, 2023, contaminated soil in the vicinity of a former hydraulic lift reported in the Phase II ESA
report was excavated. Soil samples were collected and analyzed on site once visual contamination was
no longer present. Confirmation samples CS-2-8’ through CS-6-7’ were collected from each of the over-
excavation side walls and from the base of the excavation. Each confirmation sample was submitted for
analyses of TPH-GRO and TPH-DRO using the mobile UVF laboratory and also for laboratory analyses using
EPA Method 8270 and MADEP Method EPH. All reported sample concentrations were less than the
established standards. All petroleum contaminated soil excavated during the March 2023 abatement
activities was transported to E S & J Enterprises land farm.

Based on the soil sample results, contamination at the site was sufficiently mitigated. Concentrations of
chromium are likely naturally occurring and appear to not be the result of a petroleum release. Further
assessment is not warranted for this site.

3. Residual Material:
The oil-water separator was emptied of contents during site activities; a disposal manifest for the liquids
recovered during site activities has been included as Appendix D.
4. Release information:
A release in the vicinity of the former hydraulic lift cylinders was confirmed during March 2022 Phase II
ESA activities. A release from the oil-water separator was not confirmed during the March 2023 closure
activities.

5. Soil Excavation Activities:
All excavated soil removed from beneath the former hydraulic lift and the former oil-water separator
basin during closure activities was transported from the site for proper disposal. Approximately 227 tons
of soil were removed during site activities; soil disposal manifests have been included as Appendix E.

6. Site Investigation:
On March 1, 2023, GRI personnel collected a soil sample (CS-1-7’) from beneath the former oil-water
separator at a depth of 7 feet BGS. The collected soil sample was submitted for analyses of TPH-GRO and
TPH-DRO using a mobile UVF laboratory and for laboratory analyses of VOCs using EPA Method 8260,
SVOCs using EPA Method 8270, MADEP Methods VPH and EPH, and TCLP metals.

According to historical reports, a Phase II ESA was performed in March 2022. During the ESA activities, a
concentration of TPH-DRO that exceeded the RAL was reported in a soil sample collected in the vicinity of
a former hydraulic lift. Due to these results, GRI conducted soil excavation during the February and March
2023 demolition activities.

On March 1, 2013, GRI personnel collected soil samples (HL-1-7’ and HL-2-7’) from beneath the former
hydraulic lift at depths of approximately 7 feet BGS. The collected soil samples were analyzed on site for
TPH-GRO and TPH-DRO by the mobile laboratory. Soil sample HL-2-7’ was collected from a thin layer of
saturated black sandy clay. Concentrations of TPH-GRO and TPH-DRO reported in HL-2-7’ exceed the
RALs. The area surrounding HL-2-7’ was over excavated until visual evidence of contamination was no
longer present. Following over excavation, confirmation samples (CS-2-8’ through CS-6-7’) were collected
from the base of the excavation and along the four excavation sidewalls. The collected soil samples were
submitted for analyses of TPH-GRO and TPH-DRO using the mobile UVF laboratory and for laboratory
analyses of SVOCs using EPA method 8270 and MADEP EPH.

D. FREE PRODUCT INVESTIGATION AND RECOVERY REPORT
During the February and March 2023 abatement activities, free product was not encountered.

E. GROUND WATER INVESTIGATION
During the March 2023 abatement activities, ground water was not encountered. No ground water
samples were collected during the March 2023 abatement activities.

F. INITIAL RESPONSE AND ABATEMENT ACTION
1. Initial Response Actions:
One oil-water separator was removed from the site on March 1, 2023. Additionally, contaminated soil
observed in the vicinity of a former hydraulic lift cylinder was excavated from the site. Ground water was
not encountered in the excavation basins. Upon completion of the removal and soil excavation activities,
the excavated soil was transported to the E S & J Enterprises, Inc. land farm. The excavation basins were
then backfilled with clean processed fill.

 Source Control Actions: One oil-water separator was removed from the site on March 1, 2023.
Additionally, contaminated soil in the vicinity of a former hydraulic lift cylinder was excavated,
 Contaminant Migration Control Measures: The release was to the subsurface; therefore,
contaminant migration control measures were not necessary.
 Measures Taken to Mitigate Fire/Safety Hazards: Prior to closure, the Fayetteville fire marshal
approved GRI’s removal 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: The release was to the subsurface;
therefore, contaminant migration control measures were not necessary.

G. EXCAVATION OF CONTAMINATED SOIL
1. Extent of Soil Contamination:
Over-excavation activities were conducted beneath the former hydraulic lift on March 1, 2023. The
excavation was filled upon the removal of the UST with clean processed fill.

2. Excavation Process:
The excavation activities were conducted using a track-mounted excavator and bobcat.

3. Sampling Description:
All soil samples were collected using a hand auger or from the excavator bucket by GRI personnel.
Samples were collected with clean, disposable nitrile gloves and transferred to the UVF operator
and/or shipped to SGS Analytical for laboratory analysis following proper chain-of-custody
procedures.

H. SOIL RESULTS
 Soil:
Concentrations of TPH-GRO and TPH-DRO that exceeded the RALs were reported in the soil sample
collected from HL-2-7’. Samples CS-2-8’ through CS-6-7’ collected from the over excavation of the area

surrounding HL-2-7’ did not exceed any of the applicable soil quality standards. Concentrations of
chromium that exceeded the soil-to-water MCCs and residential SCLs were reported in the soil sample
collected from CS-1-7’ and the background sample collected from BG-1-8’. Please note, that soil sample
BG-1-8’ was collected from an area that was isolated from the areas of potential contamination and also
exceeded the residential SCL. The result is likely from a naturally occurring source of chromium at the
site. A soil quality map has been included as Figure 3. A summary of soil sample analytical results is
presented as Table 1. Copies of the mobile UVF and laboratory reports are included as Appendix F. A
summary of the soil sampling data from the March 2023 abatement activities is shown below:

I. SUMMARY AND CONCLUSIONS
 On March 1, 2023, one oil-water separator was removed from the site.
 No concentrations of TPH-GRO or TPH-DRO that exceeded the RALs were reported in the soil sample
collected beneath the former oil-water separator.
 A concentration of DRO that exceeded the RAL was reported in the soil sample (HL-2-7’) collected
from beneath the former hydraulic lift.
 Over excavation activities were conducted in the vicinity of HL-2-7’, and conformation samples CS-2-
8’ though CS-6-7’ were collected from each sidewall and the base of the excavation. The UST basin

the residential SCL in an area of the site property not associated with petroleum activity, it is believed
that chromium is naturally occurring in the vicinity of the site. Concentrations of chromium observed
in soil samples collected at the site should not be considered indicative of petroleum contamination
and should not constitute a soil quality violation.
 No free product was observed in the excavation basin during abatement activities.
 Ground water was not encountered during the March 2023 UST closure activities.
 Based on this information, a soil quality violation does not exist at the site and no further assessment
is warranted.

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

Dear William Regenthal:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/10/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love Project Manager
