2.0 Executive Summary
A 10,000 gallon diesel fuel UST was closed by removal at the Bluelinx Corporation warehouse
and transportation facility located at 3300 Parkside Drive, Charlotte, North Carolina. This UST
was installed on September 15, 1992 and replaced an earlier 10,000-gallon diesel fuel UST
located in the same basin.
The closed 10,000-gallon UST was removed from the tank basin on November 29, 2022. The
UST was of double-wall fiberglass reinforced plastic (FRP) construction and measured
approximately 31 feet long by 7.5 feet in diameter. Product and vent lines were of FRP
construction and connected to a single product dispenser pump.
Approximately 288 gallons of residual diesel fuel and wash-water from emptying and cleaning
the tank prior to removal was disposed by CCI Environmental Services (CCI) at their facility in
Thomasville, North Carolina. The product lines were also drained, flushed, and capped by CCI,
as the product lines will remain in the ground. The product dispenser is also remaining in place
as it will be used for the replacement UST system. The former UST was crushed and disposed
by CCI at the Davidson County Landfill in Lexington, North Carolina.
Soil samples obtained from beneath the former UST, beneath the product and vent lines, and
from the overburden soil removed from the basin, were analyzed at the laboratory for TPH-GRO
and TPH-DRO in accordance with DEQ Guidelines for the closure of USTs. None of the soil
samples obtained identified detections of TPH-GRO or TPH-DRO, with the exception of the two
soil samples beneath the product and vent lines which had estimated TPH-DRO of less-than 10
mg/kg.
Following the removal of the former UST, overburden soil was returned to the former UST basin
and compacted, and gravel was used to fill the basin to grade. Following the addition of the
gravel, a rebar reinforced concrete cover was added for site restoration.
Based on the laboratory analytical results and visual observations, TRC has not identified a
release of petroleum hydrocarbons associated with this UST closure and recommends no
further action.

3.0 Site History and Characterization
According to the UST Database maintained by the North Carolina Department of Environmental
Quality (DEQ), a 10,000-gallon diesel fuel tank was initially installed at the UST basin location
on March 4, 1971. This UST was closed by removal on September 12, 1992. The tank owner
and operator was listed as Georgia Pacific. According to records reviewed by TRC, petroleum
soil contamination was identified at the time of closure, and the soil was excavated from the
basin at the time of the tank removal. The petroleum contaminated soil was disposed, and a
letter dated October 1, 1992 from the North Carolina Department of Environmental Health and
Natural Resources (DEHNR) provided regulatory confirmation that the petroleum soil
contamination was removed from the site and disposed.
The UST Database lists the current 10,000-gallon diesel fuel tank as being installed on
September 15, 1992. This UST was closed by removal on November 29, 2022. There were no
reported releases from this UST or ancillary product or vent lines.
The UST owner and operator are provided in Section 1.0 of this report. The closed tank was
located at the BlueLinx Corporation warehouse facility located at 3300 Parkside Drive in
Charlotte, Mecklenburg County, North Carolina (Figure 1).
The closed 10,000-gallon UST was removed from the tank basin on November 29, 2022. The
UST was of double-wall FRP construction and measured approximately 31 feet long by 7.5 feet
in diameter. Product and vent lines were of FRP construction and connected to a single product
dispenser pump. Soil samples were obtained from the base of the UST and from the
overburden soil pile at the time of closure on November 29, 2022, and no petroleum
hydrocarbon contamination was identified. Soil samples were obtained along the product and
vent lines on December 12, 2022, and no petroleum hydrocarbon contamination was identified.
The location of the former UST system is presented on Figure 2.

4.0 Closure Procedure and Sampling Assessment
Closure Procedure
Prior to the removal of the UST, the UST-3 Notice of Intent: UST Permanent Closure Form was
submitted to the DEQ on October 27, 2022 (Appendix A). The Charlotte Fire Marshal was
notified in advance of the tank closure scheduled for November 29, 2022. A public utility
notification through the NC-ONE notification system was made so that utilities could mark-out
the locations of subsurface utilities along right-of-way areas.
The UST closure by removal on November 29, 2022, was observed by TRC. The tank removal
was performed by CCI. Prior to removal, TRC retained the services of Integrated Scanning
Solutions (ISS), a private subsurface utility locating firm, to verify the locations of the UST,
product and vent lines, and subsurface utilities in the vicinity of the tank basin.
On November 28, 2022, the day prior to the removal of the UST, CCI verified that electricity was
safely locked out of the UST system. The UST was then checked for contents and CCI
determined that there was a small quantity of diesel fuel in the tank. The contents of the tank
were removed through a pump truck provided by CCI. The interior of the tank was then pressure
washed to remove residual sludge. The wash water was contained and stored in a truck-
mounted vessel for disposal. The total amount of liquid removed from the UST, including the
diesel fuel and wash water, was 288 gallons. The concrete surface above the tank basin was
cut using a concrete saw.
On November 29, 2022, the concrete cover above the UST was removed and placed at an area
beside the tank basin on a layer of Visqueen polyethylene plastic. A track hoe was used to
remove overburden soil above the tank and soil surrounding the tank and placed on the plastic
cover. Once the product line and vent line were fully exposed in the basin, the two lines were
cut and sealed as these lines were not scheduled to be removed with the UST. The Charlotte,
North Carolina Fire Marshal inspected the UST prior to removal and performed a vapor test
inside of the vessel and determined that vapors inside of the tank were below the lower
explosive limit and safe to remove. The remaining overburden soil was then removed from the
basin by CCI.
Once a sufficient amount of soil had been removed, the UST was removed from the tank basin
and loaded on to a flatbed truck using a trackhoe. The top of the tank was approximately two-
feet below the concrete surface. The UST measured approximately 31 feet in length and 7.5
feet in diameter. Four soil samples were obtained beneath the former tank location in native soil
approximately 9.5 feet below the ground surface from the bucket of the trackhoe. Additionally,
two soil samples were obtained approximately 2 feet below the product line and 2 feet below the

BlueLinx, Charlotte, NC February 7, 2023

vent line, exposed at the southwest extent of the basin. Two composite soil samples were
obtained from the stockpiled soil using a hand auger.
The final dimensions of the former UST basin excavation were approximately: 35 feet in the
northwest-southeast direction (length); 8 feet in the northeast-southwest dimension; and 9 feet
in depth.
The soil encountered was brown silty clay to a depth of approximately 9 feet below ground
surface (ft bgs). The soil encountered between 9 ft bgs and 9.5 ft bgs was silty sandy clay
saprolite with relict textures representative of the weakly foliated granitic bedrock in this area.
There was no groundwater encountered in the former tank basin. The soil sample locations are
illustrated on Figure 3.
The soil samples from beneath the former UST, the distribution lines, and composite samples
from the soil stockpile were screened in the field using a photoionization detector (PID) to
determine the presence of volatile organic compounds (VOCs). The PID readings ranged from
non-detect to a maximum of 1.9 parts-per-million (ppm) and are presented on Table 1.
Following the PID screening for each soil sample, the soil samples were placed in laboratory-
supplied containers and a pre-chilled cooler provided by Waypoint Analytical Laboratory of
Charlotte, North Carolina. The chain-of-custody was completed and each of the eight soil
samples designated for analysis for Total Petroleum Hydrocarbons (TPH) Gasoline Range
Organics (GRO) and Diesel Range Organics (DRO) in accordance with DEQ Guidelines.
Following the completion of the field sampling in the former tank basin, TRC determined that
based on the field observations and PID scanning results, the excavated soil could be returned
to the former tank basin. The excavated soil was then returned to the tank basin by CCI and
compacted. Following the soil compaction, CCI provided graded aggregate base gravel (crusher
run) to be placed on top of the soil in the former basin. The gravel base was added to the former
basin to grade.
On December 12, 2022, a drill rig using Direct Push Technology (DPT) was used to advance
two shallow soil borings through the concrete in the vicinity of the product line run from the
dispenser pump to the former UST basin. Due to the continued use of the subject property, and
truck traffic in this part of the property, it was not practical to remove the product lines.
Therefore, the product lines remain as abandoned in-place with the two soil samples providing
data for their closure. The approximate length of product line was 17 feet from the dispenser
pump to the edge of the tank basin, therefore, two soil samples were obtained: one near the
product dispenser and the one near the center of the product line run. This line sampling
augmented the samples obtained at the time of the tank removal from within the UST basin. The

BlueLinx, Charlotte, NC February 7, 2023
7

product lines were measured to be approximately 2 feet below the concrete, and the samples
were obtained at 2.5 feet below the concrete, or, 0.5 feet below the lines. The two soil samples
were analyzed at Waypoint Analytical Laboratory for TPH GRO and TPH DRO. The location of
the line samples are illustrated on Figure 3.
Both the product line and vent line extend from the dispenser pump to the former UST basin
with a gentle slop towards the basin. The depth of these lines are approximately 2 ft bgs below
the concrete at the dispenser pump and approximately 2.5 ft bgs below the concrete at the
former UST basin. The purpose of this downward slope is based on the design of the former
UST system utilizing a European Suction System where product returns through the line to the
tank when not being pumped.
Sampling Assessment
The laboratory analytical results from the soil sampling from below the UST, the product lines,
and the soil pile were all below the DEQ criteria for TPH GRO and TPH DRO. The soil sampling
results are summarized below and presented in Table 2. The sampling locations are illustrated
on Figure 3, the DEQ Site Investigation Report for Closure (UST-2 Form) is provided in
Appendix B, and the laboratory report is provided in Appendix C.

Liquid and UST Disposal / Site Restoration
The residual diesel fuel and wash-water contents from the tank were transported by CCI for
disposal at their licensed waste disposal facility in Thomasville, North Carolina. According to the
non-hazardous waste manifest, the total quantity of diesel fuel and wash-water disposed was
288 gallons.

The former UST was transported by CCI for disposal at the Davidson County Landfill in
Lexington, North Carolina. According to the non-hazardous waste manifest, one empty (and
crushed) 10,000 fiberglass UST, weighing approximately 11,420 pounds, was disposed. The
manifests are provided in Appendix D.
On December 30, 2022, CCI’s contractor, Petrishen Concrete, LLC of Mocksville, North
Carolina, completed the site restoration by providing a concrete cover over the former UST
basin.

5.0 Summary
On November 29, 2022, the 10,000-gallon diesel fuel UST was closed by removal. The ancillary
product line and vent line were capped and abandoned in-place. Overburden soil that was
removed from the former tank basin was returned to the basin following the removal of the tank.
Soil samples obtained from beneath the former UST and beneath the product line and vent line
were analyzed at the laboratory for TPH-GRO and TPH-DRO in accordance with DEQ
Guidelines for the closure of USTs. None of the soil samples obtained identified detections of
TPH-GRO or TPH-DRO, with the exception of the two soil samples beneath the product and
vent lines which had estimated TPH-DRO of less-than 10 mg/kg.
Based on the laboratory analytical results and visual observations, TRC has not identified a
release of petroleum hydrocarbons associated with this UST closure and recommends no
further action.

Client: TRC Environmental Corporation CASE NARRATIVE
Project: Bluelinx UST Lab Report Number: 22-333-0005
Date: 12/1/2022
Total Petroleum Hydrocarbons - Extractable Method 8015C DRO QC Batch No: V27119/V27062 Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the
batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be acceptable.
Total Petroleum Hydrocarbons - Volatile Method 8015C GRO
Sample 94271 (PL-1 4.5') Analyte: a,a,a-Trifluorotoluene
QC Batch No: V27090/V27089 Surrogate(s) exhibited a high bias in this project sample where no target analytes were detected. The high
recovery(s) had no impact on the data. Batch QC samples (method blank and laboratory control samples) all showed surrogates within QC limits.

Dear Natalie Stevens:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/13/2022 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,
Angela D Overcash Senior Project Manager
