Surface water was not identified within 500 feet of the site. The nearest surface water body has
been identified as Big Branch which is located approximately 1,900 feet east of the Concrete
Basin. Big Branch (Stream Index 18-31-24-5-1) is designated as a Class C surface water classification from its source to Beaver Creek.

F. UST System Information
The Concrete Basin removed at the facility was owned and operated by Fort Bragg Environmental Compliance Branch. Concrete Basin owner and system information has been provided in Table 1 and Table 2. A site plan map illustrating the location of the removed
Concrete Basin in relation to other pertinent site features has been included on the attached Figure 2.
II. Closure Procedures
A. Describe preparations for closure including the steps taken to notify authorities, permits obtained and the steps taken to clean and purge the tanks: - A Notice of Intent: UST Permanent Closure or Change-in-Service (UST-3) form was not
formally submitted to the North Carolina Department of Environmental Quality (NCDEQ) – Fayetteville Regional Office (RRO).
- One approximate 30,000-gallon capacity Concrete Basin that formerly contained used motor oil and water was removed from the location shown in Figure 2.
- HERR cleaned the Concrete Basin prior to removal with the use of a vacuum truck and pressure washer provided by HERR.

- A copy of the Site Investigation Report for Permanent Closure or Change-In-Service for unregistered tanks (UST-2B) form for the Concrete Basin has been submitted with this
report and is attached in Appendix A.
- The 30,000-gallon capacity Concrete constructed basin was measured to be
approximately 42 feet long by 15 feet wide by 6 feet deep. The concrete was a minimum of 18 inches thick on the sidewalls and bottom.
- Based on the soil analytical results received on July 29, 2022 for Benzo(a)pyrene and Hexavalent Chromium that exceeded the Soil to Groundwater Maximum Soil Contaminant Concentrations (MSCCs), a 24-Hour Release and UST Leak Reporting
Form (UST-61) was prepared and submitted to the NCDEQ-FRO on August 3, 2022 (Appendix A).

B. Note the amount of residual material pumped from the tank(s):
A total of 10,196 gallons of residual liquid and sludge materials were evacuated from the
Concrete Basin system by HERR’s onsite vacuum truck from June 14, 2022 to June 24, 2022.
The total for D-2367 is included on the disposal transportation manifests for liquids/sludge included in Appendix B. Photo-documentation of the removal activities are attached in
Appendix C. C. Describe the storage, handling, and disposal of the residual material: All liquids/sludge were transported for disposal to HERR’s facility located in Whiteville, NC. A disposal manifest for the liquids are included in Appendix B.
D. Excavations
1. Describe excavation procedures noting the condition of the soils and the dimensions of the excavation in relation to the tanks, piping and/or pumps:

Concrete Basin Excavation
Excavation of the Concrete Basin occurred on June 23 and 24, 2022. Impacted soil was not
observed to be present by visual, olfactory, and/or PID field screening methods.
Prior to the removal, the Concrete Basin was evacuated of all residual liquid/sludge and then
pressure washed. The liquid/sludge materials were removed under vacuum with the use of a vacuum truck provided by HERR. Manifests for transport and disposal of the liquid/sludge have
been included in Appendix B. Following removal of the concrete bottom and sides, six closure soil samples were collected. Four
samples, UC-1 to UC-4 were collected along the bottom center of the basin at a depth of 8 feet below ground surface (bgs). Two soil samples, SW-1 and SW-2, were collected from the north and south geographic sidewalls. The sample locations are shown on Figure 3. Petroleum odors
and elevated PID readings were not present in the soils and over-excavation was not performed for initial abatement. The final Concrete Basin excavation dimensions were measured to be approximately 15 feet wide (N-S) by 42 feet long (E-W) by 8.0 feet deep.
2. Note the depth of tank burial(s) (from land surface to top of tank):

The Concrete Basin was buried approximately 0.25 feet bgs.
3. Quantity of soil removed:
Not applicable.
4. Describe soil type(s):
Site geology has been characterized through observations of the bottom and sidewalls of the excavated Concrete Basin. Soil excavation observations indicate that native soil material consists of a red brown to tan sandy silt to a maximum excavation depth of 8.0 feet below ground surface
(bgs). Groundwater nor bedrock was encountered during the removal of the Concrete Basin.

5. Type and source of backfill used:
The backfill was provided by and delivered to the site by HERR which obtained the material from
a local source.
E. Petroleum Hydrocarbon Impacted Soil 1. Describe how it was determined to what extent to excavate the soil:
Over-excavation was not performed.
2. Describe method of temporary storage, sampling and treatment/disposal of soil:

No impacted soils were identified to be present by field screening activities on the date of the Concrete Basin closure.

III. Site Investigation

A. Provide information on field screening and observations, include methods used to calibrate field screening instrument(s):
Field screening was performed during the Concrete Basin system closure soil sampling activities on June 24, 2022. Field screening was performed using a MiniRae 3000 PID calibrated in
accordance with manufacturer’s instructions using a 100 ppm Isobutylene span gas.
B. Describe soil sampling points and sampling procedures used, including:
- Location of samples - Type of samples (from excavation, stockpiled soil, etc.)
- Sample collection procedures (grab, split spoon, hand auger, etc.) - Depth of soil samples (below land surface)
- Whether samples were taken from side or floor of an excavation
- Sample identification and analyses

Each soil sample was collected utilizing new disposable powder-free nitrile gloves to prevent the possibility of cross-contamination. The soil samples were collected at a depth of 8.0 feet bgs from
the center of the excavation basin and at 6.0 feet bgs on the sidewalls using the mini-trackhoe. Upon collection, the soil was immediately placed within appropriate laboratory supplied/preserved sample containers and emplaced within an ice chilled cooler for transportation
to Environmental Conservation Laboratories, Inc. (ENCO), a North Carolina certified laboratory
located in Cary, North Carolina.

6
The soil samples collected for the Concrete Basin closure were submitted for laboratory analysis
by EPA Method 8260 for Volatile Organic Compounds (VOCs), EPA Method 8270 for Semi-
volatile Organic Compounds (SVOCs), Massachusetts Department of Environmental Protection (MADEP) Volatile Petroleum Hydrocarbons (VPH) and Extractable Petroleum Hydrocarbons
(EPH), and by EPA Method 6010D for total Chromium (Cr), and Lead (Pb). In addition,
Hexavalent Chromium was analyzed by EPA Method 7196 so that a calculation could be made to determine the concentration of Trivalent Chromium (Total Chromium – Hexavalent Chromium =
Trivalent Chromium). The location of the closure soil samples are depicted on Figure 3. C. Describe groundwater or surface water sampling procedures used, including: No groundwater or surface water sampling procedures were utilized during closure activities.
D. Quality control measures - Describe sample handling procedures including sample preservation and transportation:
All soil samples were collected in laboratory supplied/preserved containers, placed within an ice
chilled cooler, and transported to ENCO, a North Carolina certified laboratory, located in Cary,
North Carolina for analyses.
- Describe decontamination procedures used:
The soil samples were collected using the mini-trackhoe. All samples were collected
using new disposable powder-free nitrile gloves. - Describe time and date samples were collected and date submitted to lab:
The Concrete Basin system closure soil samples were collected on June 24, 2022 during removal activities. The samples were submitted to the analytical laboratory as per the date and
time on the chain of custody records that are located in Appendix D. - Describe samples collected for quality control purposes
(e.g. duplicates, field blanks, trip blanks, etc.) Include methods used to obtain these samples and analytical parameters: N/A

- Discuss how results of quality control samples may have affected your interpretation of soil, groundwater or surface water sample results: N/A

E. Investigation results - Describe methods of analyses used (include U.S. EPA method number) - Describe analytical results for samples; discuss in relation to site specific cleanup level or action level, as appropriate
EPA Method 8260 and EPA Method 8270 analytical results are summarized in Table 3. MADEP VPH and EPH analytical results are summarized in Table 4. Total Chromium (Cr) and Lead (Pb)
results are summarized on Table 5. Soil sample locations are shown on Figure 3. Complete laboratory reports with COC documentation have been included in Appendix D.

7
Analysis by EPA Method 8260 indicated a detectable concentration of the target compounds
Toluene, Naphthalene, and Total Xylenes in one or more soil samples. No other target EPA 8260
Method compound was reported to be present above the method detection limit. Of the reported detectable concentrations, none were reported to be in exceedance of the Soil to Groundwater
Maximum Soil Contaminant Concentrations (MSCCs).
Analysis by EPA Method 8270 indicated an estimated or detectable concentration of multiple
target compounds in one or more soil samples. Of the reported estimated and detectable concentrations, the concentration of Benzo(a)pyrene was reported to be in exceedance of the Soil to Groundwater MSCC but less than the Residential MSCC in samples UC-1 and SW-5.
Analysis by MADEP EPH and VPH did not reveal the presence of any detectable concentration of the targeted petroleum hydrocarbon fractions in the sample.
Analysis for Total Chromium (Cr) and lead (Pb) by EPA 6010D and for Hexavalent Chromium by EPA Method 7196 indicated a detectable concentration of total Chromium, total lead, and
Hexavalent Chromium in every sample. Trivalent Chromium was then calculated as the difference between total Chromium and Hexavalent Chromium. Of the reported and calculated
concentrations, Hexavalent Chromium was reported in excess of the corresponding Soil to
Groundwater MSCC of 3.8 mg/Kg and the Residential MSCC of 1.32 mg/Kg in soil sample SW-6. Lead (Pb) was reported to be present at a concentration less than the Soil to Groundwater
MSCC in every sample.
Based on the soil analytical results received on July 29, 2022 for Benzo(a)pyrene and Hexavalent
Chromium, a 24-Hour Release and UST Leak Reporting Form (UST-61) was prepared and submitted to the NCDEQ-FRO (Appendix A).

IV. Closure Report Summary

This Concrete Basin Closure Report has been completed to present soil quality analytical
information resultant from the removal of a Concrete Basin system at the Fort Bragg site D-2367 located in Fort Bragg, Cumberland County, North Carolina.

Summary
One approximate 30,000-gallon Concrete Basin was removed from the site.
Results, Recommendations, and Conclusions

Results of the closure soil sampling from the Concrete Basin has indicated that soil quality for both Benzo(a)pyrene and Hexavalent Chromium exceeded the Soil to Groundwater MSCC,
Hexavalent Chromium also exceeded the Residential MSCC but not the Industrial/Commercial MSCC.
Based upon the closure soil analytical results, it is possible that additional assessment or remediation work may be required. Final decisions however will be made following the review of
this report by the NCDEQ-FRO UST Section. EMS on behalf of Fort Bragg Environmental
Compliance Branch respectfully requests that return correspondence from the NCDEQ be issued indicating their receipt and review of this report.

Definitions of Sources Tank: means the tank that stores the product and is part of the underground storage tank system Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end-use equipment (Vent, vapor recovery, or fill lines are excluded.) Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor recovery lines, and fill lines) Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser) Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser) Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken components, and components that have changed dimension) Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust) Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells) Unknown: use when the cause has not been determined

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.

N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL
Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC]
Result may be biased high. Associated calibration verification standard exceeded the upper control limit.J-04
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-07
Precision between duplicate matrix spikes of the same sample was outside acceptance limits.QM-11
Surrogate recovery outside acceptance limitsQS-03
The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
