RE: January 2023 Groundwater Monitoring Report
TransMontaigne – Greensboro Terminal
6801 W. Market St., Greensboro, Guilford County, North Carolina
NCDENR Incident No. 6367

Dear Mr. Mao:

This letter presents a report of groundwater sampling and analysis completed in January 2023 for the
TransMontaigne-Greensboro petroleum bulk terminal and transportation terminal referenced above in
Greensboro, North Carolina. The groundwater sampling/analysis event was completed as requested in your
January 6, 2023 email to Doug Hall of TransMontaigne.

1.0 GROUNDWATER SAMPLING AND ANALYSIS METHODS

The site location and layout are shown in Figures 1 and 2 (Attachment 1). Site groundwater monitoring-well
construction details are listed in Table 1 (Attachment 2).

Site groundwater sampling was completed on January 17-19 and January 30, 2023. The event included fourteen
site monitoring wells listed as follows.

• MW-5
• MW-9
• MW-14
• MW-17
• MW-18
• MW-20A
• MW-24A
• MW-38
• MW-39
• MW-49
• MW-57
• MW-58
• MW-59
• MW-60

A subset of the above monitoring wells, including MW-9, MW-14, MW-18, MW-20A, MW-24A, MW-38, and
MW-49, were selected for groundwater sampling based on a previous evaluation of groundwater monitoring
events through 2018, which indicated increasing groundwater chemical of concern (COC) concentrations, or
notable spikes in groundwater COC concentrations, during recent previous years.1 Monitoring-wells MW-57

through MW-60 were added to the event as monitoring points installed (in 2017) to detect and monitor
groundwater COC concentrations encroaching beneath the TransMontaigne property from the adjacent,
upgradient former GNC Energy terminal to the east. MW-5 and MW-39 were added to the event as monitoring
wells that have historically demonstrated relatively high concentrations of specific site groundwater COCs.
Shallow-saprolite monitoring-well MW-17, which is clustered with deep-saprolite and bedrock monitoring-
wells MW-18 and MW-49, was added to complement the sampling/analysis results for those wells.

As the first step of groundwater sampling, on January 17, 2023, groundwater levels were measured in all site
monitoring-wells, except MW-45, utilizing an optical interface probe, which distinguishes between groundwater
and liquid-phase hydrocarbons (LPH, a.k.a. “free product”). MW-45 was blocked from access on January 17
but was subsequently accessed and gauged on January 30, 2023.

Following gauging, each well to be sampled was purged of three volumes of groundwater or until dry using
either a dedicated disposal bailer and nylon rope or a submersible pump with dedicated, disposable tubing. The
submersible pump was cleaned with a soap and tap water wash and a distilled water rinse prior to each
use. Following removal of each standing volume of groundwater, field measurements of purge-water pH,
temperature, dissolved oxygen (DO), and specific conductance were collected. Following well purging,
groundwater samples were collected within 24 hours, using dedicated, disposable bailers and nylon
rope. Groundwater samples were stored on ice in a cooler, shipped under chain of custody to Pace Analytical,
and analyzed for benzene, toluene, ethylbenzene, xylenes (BTEX), methyl tert-butyl ether (MTBE), 1,2-
dichloroethane (1,2-DCA), naphthalene, and isopropylbenzene by EPA Method 8260D.

2.0 GROUNDWATER SAMPLING AND ANALYSIS RESULTS

Tabulated site monitoring-well gauging data are provided in Attachment 3. Observed site groundwater levels in
January 2023 ranged from approximately 3- to 20-feet below grade. LPH was not detected in any site
monitoring wells.

Groundwater potentiometric-surface contour maps for the shallow-saprolite, deep-saprolite, and bedrock aquifer
zones based on January 2023 site groundwater levels are provided as Figures 3 through 5. All three maps
illustrate a similar semi-radial pattern of groundwater potentiometric-surface contours with a west-northwest-
oriented axis situated in the northern portion of the terminal property, and apparent groundwater flow directions
toward the southwest, west-northwest, and northwest to northeast.

Results of laboratory analysis of January 2023 site groundwater samples are summarized in Table 2. A
historical summary of site groundwater analysis results is provided in Table3. Laboratory reports of analysis are
provided in Attachment 4.

3.0 DISCUSSION

TransMontaigne and predecessors have completed various site assessment and remediation efforts since around
the late 1980s to address historical site soil and groundwater contamination under NCDEQ Incident No. 6367.
Sitewide active soil/groundwater remediation was conducted from 2001 through 2015. Initial efforts from 2001-

2009 involved the operation of a combined groundwater/free-product recovery and soil vacuum extraction
(SVE) system. Subsequent efforts from 2009-2015 involved the operation of a combined air sparging/SVE
system.

A New Technology Cleanup Plan (NTCP) was submitted to NCDEQ in May 2017.2 The NTCP provided a
proposal to expand the site air sparging system to enhance groundwater remediation in the area of a well with
lingering benzene concentrations above the GCL. The report also stressed TransMontaigne’s plan to proceed
with NCDEQ requirements for risk-based site regulatory closure per 15A NCAC 2L .0507(d) following
achievement of GCL compliance.

NCDEQ approval of the May 2017 NTCP was transmitted via a May 22, 2017 letter to TransMontaigne.
NCDEQ’s position on risk-based closure was further clarified in a February 5, 2018 letter to TransMontaigne,
which stated that NCDEQ “may consider site closure under risk-based rules if no GCL violations are detected
in four (4) consecutive quarterly groundwater-monitoring events after shutdown of the active remediation
system.” NCDEQ’s position on this matter was subsequently reinforced via a February 7, 2018 email between
NCDEQ and Piedmont Geologic, in which NCDEQ agreed that there was no reason being considered that
would prevent a risk-based closure implementation following achievement of the GCL compliance per above.

Achievement of the stated GCL compliance occurred through quarterly groundwater monitoring events
completed from March 2018 to February 2019. Accordingly, TransMontaigne initiated the process of pursuing
risk-based site closure. NCDEQ involvement in this process is documented in a series of emails between
NCDEQ and Piedmont Geologic from February 21 to March 4, 2019 (Attachment 5), which reflected
NCDEQ’s intentions on issuing a notification of conditional No Further Action (NFA) following: 1) submittal
and NCDEQ approval of a Notice of Residual Petroleum (NRP), and 2) execution of a Property Owner Consent
to Risk-Based Remediation by Products Pipe Line Company (PPL), who own the terminal property (6367 Burnt
Poplar Drive) directly west of the TransMontaigne property. This latter requirement was ostensibly based on the
detections of groundwater COCs at concentrations above 2L standards in TransMontaigne monitoring-wells
MW-18 and MW-49, in the southwestern site area.

Following contact by TransMontaigne, PPL declined to cooperate in the process of executing the Property
Owner Consent on behalf of TransMontaigne.

In response to PPL’s decision per above, a meeting was held between NCDEQ and TransMontaigne
representatives on April 17, 2019 during which TransMontaigne presented a demonstration that increasing
groundwater COC concentrations observed in MW-18 and MW-49 were the result of encroachment from the
former GNC Energy site east of the TransMontaigne terminal. Suspicion of this encroachment had led
TransMontaigne to install the multi-level well cluster at the northeast terminal corner (MW-57 through MW-60)
in February 2017, with subsequent sampling/analysis of groundwater samples from these wells confirming the
suspicion, as discussed above. An April 19, 2019 letter from Piedmont Geologic to NCDEQ (via Guilford
County Department of Public Health) provided a summary of the facts, presentations, and findings presented to
NCDEQ during the April 17, 2019 meeting. The letter concluded with a request that NCDEQ grant a waiver to

the requirement for PPL Property Owner Consent as a requirement of site risk-based closure for Incident No.
6367.

NCDEQ response to the April 19, 2019 letter was not received until a July 30, 2020 email to TransMontaigne.
The email did not include a waiver to the PPL Property Owner Consent as requested above but conceded that
groundwater COC concentrations from both the TransMontaigne site and GNC Energy site are comingled. The
email further stated that TransMontaigne was “required to deal with your contamination on your property and
the upgradient source [former GNC Energy site] must deal with theirs.”

The April 19, 2019 email referenced above included an unsigned and undated letter to TransMontaigne,
providing rebuttals to findings presented in the April 19, 2019 letter from Piedmont Geologic to NCDEQ
referenced above. This April 19, 2019 letter is provided herein in Attachment 6. There are several factual errors
in the letter and other suppositions that may be negated through results of January 2023 site groundwater
monitoring. These are not detailed in full herein but may be revisited by TransMontaigne in the future as
warranted. However, it is important to correct certain errors in the NCDEQ letter regarding locations of
TransMontaigne site monitoring wells with respect to the PPL property, as these errors may have led to flawed
conclusions on the part of NCDEQ regarding TransMontaigne’s current eligibility for risk-based closure
without the cooperation of PPL.

The April 19, 2019 NCDEQ letter states that several site monitoring wells in the southernmost limit of the
TransMontaigne site monitoring-well network, namely MW-15, MW-16, MW-17, MW-18, and MW-49, are
located on offsite property, or, that is, property owned by PPL (6316 Burnt Poplar Road). This is incorrect. All
of the referenced monitoring wells are on property owned by TransMontaigne, as shown in the Guilford County
property map in Figure 6. No TransMontaigne monitoring wells are on any offsite, third-party, properties to the
east, west, or south. Accordingly, there is no confirmation that encroachment of groundwater COCs from the
TransMontaigne property to the PPL property has occurred.

If risk-based closure for the TransMontaigne site remains contingent upon PPL consent, it is believed that such
consent may eventually be granted if/when PPL pursues risk-based closure for petroleum contamination on own
their property (Incident No. 3367, 6316 Burnt Poplar Drive), as such contamination is encroaching onto
TransMontaigne-owned property (the former Hess terminal) at 6907-B W. Market Street (Figure 6). Such
encroachment is illustrated in the PPL March 2022 groundwater BTEX isoconcentration map in Attachment 7.3

It is noted that BTEX isoconcentration contour maps included in groundwater monitoring reports for PPL
Incident No. 3367, such as the example in Attachment 7, have included a notation regarding the area where the
groundwater BTEX distribution from the PPL property encroaches onto the TransMontaigne (former Hess). The
notation, stating “see historical TransMontaigne/Hess monitoring data for information on BTEX detections near
western property boundary,” would appear to be intended to lead regulatory personnel or others into concluding
that groundwater BTEX concentrations on the TransMontaigne (former Hess) property are the result of release
incidents by Hess/TransMontaigne. However, no such incidents are known of, and no NCDEQ Incident No. is

assigned to the TransMontaigne (former Hess) property, as documented in a June 5, 2013 letter from Piedmont
Geologic to NCDEQ4, provided in Attachment 8.

As per above, TransMontaigne objects to PPL’s false claims/notations and requests that NCDEQ instruct PPL
to remove the incorrect and misleading notation from all future groundwater-related maps/presentations for the
PPL site. Furthermore, TransMontaigne would expect that NCDEQ require PPL to obtain Property Owner
Consent to Risk-Based Remediation from TransMontaigne for future risk-based closure of their property, if the
same requirement remains in effect for TransMontaigne with respect to Incident No. 6367 (i.e., 6801 W. Market
Street).

Finally, TransMontaigne continues to maintain a network of 75+ site monitoring and remediation wells, which
incur high annual Greensboro County permitting fees, as well as other obligations/responsibilities.
TransMontaigne does not agree with any present or potential future requirement to re-implement site
groundwater monitoring or remediation for Incident No. 6367, as the site would already have been issued risk-
based regulatory closure with one signature being procured from PPL, and results of January 2023 site
groundwater sampling/analysis indicate no changes in site conditions that would warrant negation of risk-based
closure (i.e., groundwater COC concentrations remain below GCLs). TransMontaigne, however, is willing to
retain a reasonably limited number of site monitoring wells for potential future contingency purposes, provided
that future Guilford County permitting fees are waived. Otherwise, TransMontaigne requests that NCDEQ
allow for abandonment of site monitoring wells per 15A NCAC 2C, under the assurance that no future
monitoring well replacements are required for those abandoned, absent of a new release incident.

Professional certification for this report is provided in Attachment 9. Should you have any questions or want
additional information, please contact the undersigned at [phone] or [e-mail].

Sincerely,

Peter J. Dressel

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.

Gene,

In response to your questions below about retaining some site monitoring wells following closure,
we are requesting to retain 16 site monitoring wells for early release detection monitoring
purposes.  The selected wells are highlighted in the attached site map and well-specifications table. 
The wells are located around aboveground storage tanks and the loading rack area and will remain
secured with protective steel casings or manholes, plus locking plugs.  All other site wells will be
decommissioned in accordance with the 2C regulations.

Let me know if you have any questions.  Thank you.

Your draft NRP indicates that there are 5 parcels of lands that TransMontaign owns. I would like to
have a map showing the tract number for each parcel to help me to know which is which.

On the top of the NRP, after the site name, you need to have the address, 2 incident numbers, and
book and page numbers of previous deeds that show the property owners describe the parcels.

When I receive your revised one, I will look at it and then issue an conditional NFA.

Will you keep some MWs after site closure?

Thanks

Pete- When the 2L rules were codified on March 1, 2016 to include aboveground storagetanks and spills under 15A NCAC 2L .0500, the rules were meant to be the same forboth USTs and ASTs with a few differences including no limitation on work due totrust fund solvency issues.  Once this occurred we began using the Notice of ResidualPetroleum (NRP). Then there was a debate of the way the statute was written, and itwas to the AGs office for clarification and a potential rule change. During this interimtime, we had to use the Notice of Contaminated Sites (NCS). I am really not sure whathappened or how it was resolved on the rule change, but we were given the approval touse the NRP with the off-site owner consent to risk based cleanup if thecontamination has migrated to their property or the potential to migrate there sometime last year. It is sort of an easier NCS. So, Gene has given you the correctinstructions. Carin Lee Kromm, L.G.

Gene:

I am confused because the Notice of Residual Petroleum and Declaration of Perpetual Land Use
Restriction you reference below are, to my understanding, relevant to UST sites, and not to non-UST
petroleum release sites like the Greensboro terminal.

Doug and I completed the risk-based closure process in early 2017 for a TransMontaigne terminal in
Selma, NC.  The process for that site, which like Greensboro is a non-UST petroleum release site, was
different than what you describe below.  For the Selma site we completed a Notice of Contaminated
Site (NOCS), including the survey plat and the written declaration.  We did not need to do the offsite
Property Owner Consent because that was not applicable for the Selma site.  After we submitted the
Notice of Contaminated Site to DEQ for review, we received the Conditional Notice of No-Further
Action.  We then filed the Notice of Contaminated Site and Plat with the Register of Deeds and
completed the public notice process.  Then, we were issued the final Notice of No-Further Action.

For the Greensboro site, we do want to restrict only the portions of the property that are impacted. 
Therefore, I understand that the survey plat will be necessary.  We also understand that the
Property Owner Consent is necessary for the Plantation Pipe Line property adjacent to the
southwest portion of the TransMontaigne terminal.

The draft Notice of Contaminated Site, and the draft Property Owner Consent form, that we have
developed for the TransMontaigne-Greensboro terminal are attached.  Please let me know if these
are the correct documents, and most recent versions, to use for the Greensboro terminal.

If the procedures have changed since 2017, and we are now required to complete the final risk-
based closure process in accordance with the guidelines for UST sites, please let me know that as
well.

Thank you.

Pete,

I think we talk about the NRP after the new release from a tank on 10/19/18. If you do restriction on
whole property, you do not need to do the survey. But if you restrict certain areas, then you need to
have the survey.

You can use the NRP for the site now as the one you use for UST. You do not need to do DPLUR. But
you need to have Property Owner Consent.

Thanks.

UNDATED/UNSIGNED LETTER
ATTACHED TO APRIL 19, 2019 NCDEQ EMAIL

Doug and Pete,

I am sending this response to the letter of April 19, 2019 from Piedmont Geologic that MTBE detected in bedrock
monitoring well MW-49 on adjacent property at 6316 Burnt Poplar Road is from an upgradient source at former GNC
Energy Enterprises site (GNC) and TransMontaigne is not responsible for MTBE detected on downgradient offsite
property.

The review of the assessment and monitoring reports for GNC and Southeast Terminals-Unocal (SE Terminals) sites
indicates that contaminant plumes have extended to northeast corner of SE Terminals site from GNC site. But we do not
believe that all MTBE in the bedrock wells at SE Terminals site is from GNC site and that MTBE has migrated through
bedrock cross SE Terminals property to MW-49, a bedrock installed on an offsite property downgradient from SE
Terminals.

The tank farm terminal at 6801 W. Market Street, Greensboro, North Carolina was reportedly constructed in 1954 and
has been operated by several corporations including current TransMontaigne Product Services, Inc. for bulk storage and
distribution of gasoline and diesel fuel. The soil and groundwater assessments conducted at the site since late 1980s
confirmed releases of petroleum products from the AST system at the terminal facility. But the dates and amounts of
releases of petroleum products are unknown since the operation of the terminal facility.

The review of the historical groundwater measurement data indicate that free product was detected in monitoring wells
MW-29, GWE-9, GWE-10, and GWE-11 between the railroad track and loading station and in MW-12, MW-37, MW-
39 between Tanks 102, 103, and 113. High BTEX and MTBE have been detected in shallow wells MW-1, -5, -6, -12, -
19, -21, -22, -35, -37, -39, SME-8, -9, GWE-1, -2, -3, -5, -6, -7, -8, -9, -10, -11, -12, -24B and deep well MW-24A.

The increase in MTBE concentration in MW-24A could not be used as an indication of source from upgradient GNC site
after shutdown of the groundwater extraction (GWE) system. Deep-saprolite well MW-24A (60 ft) and shallow well
MW-24B (39 ft) are located immediately downgradient from the major source area for free product/groundwater
contamination and extraction wells (35 ft). During the operation of the GWE system from 2001 to 2009, the influence of
groundwater extraction on deep saprolite zone could be significantly less than on shallow aquifer due to the depth of
saprolite and the distance (~100 ft) of MW-24A from the extraction points. After shutdown of the GWE system, highly
contaminated groundwater trapped in saprolite and shallow zone where groundwater could not be extracted would move
to MW-24A and result in the increase in contaminant concentrations. After GWE system shutdown, continuous operation
of SVE system would not be effective for groundwater contamination in saprolite below 60 feet deep while groundwater
table is less than 20 ft below ground surface. MW-24B (39 ft) was used as an AS point in 2011, but the impact of the air
sparging would not be significant on the contaminants in saprolite more than 60 feet deep.

No bedrock monitoring wells were installed in the source area mentioned above.

The review of historical groundwater sampling results indicates that MTBE has been detected in shallow wells including
onsite MW-5, MW-22, MW-23, GWE-12 and offsite MW-15 and MW-17 located southwest near the property line. MTBE
was detected in onsite MW-5 ranging from 1,700 to 33,000 ppb from 1994 to 2005 and has decreased since the addition
of extraction well GWE-12 approximately 15 feet upgradient in 2004. After shutdown of the GWE system in 2009, MTBE
in MW-5 has rebounded to 1,610 ppb in 2017. But MW-5 was not used for the construction of cross sections to show
the vertical extent of MTBE and discussion on historical MTBE concentrations in the letter of February 21, 2019
from TransMontaigne. MTBE has been detected in downgradient onsite well MW-23 and in offsite wells MW-15 and
MW-17 from 1990 to 2000 southwest on both sides of the properties.

The review of MTBE of March 6, 2017 in intermediate wells of similar depths (60-62 feet) indicates that MTBE was
detected in onsite MW-20A, MW-14 and offsite MW-16 and MW-18 near the southwestern property line. MTBE in
offsite MW-16 was none-detected from 1994 to 2002 but has been detected at concentration higher than its 2L standard
since 2003. MTBE was non-detected in offsite well MW-17 in 1994 but was detected from 1998 to 2016.

MTBE detected historically in shallow and intermediate wells onsite and offsite indicates MTBE plume has migrated
downgradient to offsite property from Southeast Terminal site. The closest source for the offsite groundwater
contamination could be from MW-5 and GWE-12 area and from the groundwater contamination zone through the central
part of the terminal facility.

Because no bedrock wells have been installed in the areas between MW-57 and MW-8, between MW-9 and MW-16, and
between MW-5 and MW-23, potential source for MTBE in MW-49 from Southeast Terminal cannot be excluded.

RE: Response to February 18, 2003 Letter to TransMontaigne
Regarding Former Amerada Hess Terminal

Dear Ms. Kromm:

This letter is on behalf of TransMontaigne in response to the February 18, 2013 letter from the North Carolina
Department of Environment and Natural Resources (NCDENR) to TransMontaigne regarding the former Amerada
Hess terminal referenced above in Greensboro, North Carolina (former Hess terminal). TransMontaigne acquired
the former Hess terminal in 1999, and the terminal was taken out of service in 2004. No petroleum products have
been stored or handled at the terminal since that latter time.
The February 13, 2013 NCDENR letter requests that TransMontaigne conduct a site assessment to evaluate ifthe
former Hess terminal is the source of groundwater chemicals of concern (COCs), specifically methyl tert-butyl ether
(MTBE), detected in groundwater samples collected in November 2004 from temporary monitoring wells installed
on the HD Supply Inc. (former Hughes Supply Inc.) property located at 6344 Burnt Poplar Road. The HD Supply
property is located directly south of the southeast comer of the former Hess terminal property.
A copy of a site map showing the locations of the temporary monitoring wells on the HD Supply property is
attached as Exhibit A (from Universal Engineering Sciences, Inc. (UES), November 20041). MTBE was detected in
November 2004 groundwater samples collected from three of four groundwater monitoring wells on the HD Supply
property, and the detected MTBE concentration in one of these samples (440 ug/L, monitoring-well TMW-1) was
above the North Carolina groundwater standard (15A NCAC 2L .0202) effective in both 2004 (200 ug/L) and
currently (20 ug/L). Detected MTBE concentrations (20 ug/L and 16 ug/L) in two of the November 2004

groundwater samples (monitoring-wells TMW-2 and TMW-3, respectively) were at and/or below 2004 and current
groundwater standards. Chlorobenzene also was detected in monitoring-wells TMW-1, TMW-2, and TMW-3 at
concentrations below the 2004, and current, groundwater standard (50 ug/L). No groundwater COCs were detected
in the November 2004 groundwater sample collected from the fourth temporary monitoring well (TMW-4) on the
HD Supply property.

In support of the preparation of this letter, reports, letters, and records on file at the Guilford County Environmental
Health Division (EHD), for both the former Hess terminal and the adjacent Plantation Pipe Line – Greensboro Bulk
Petroleum Breakout Facility (Plantation facility), were reviewed on May 29, 2012. The Plantation facility is located
at 6907-A West Market Street, directly east of the former Hess terminal, with a portion situated directly south of the
southeast corner of the former Hess terminal, and directly east and northeast of the HD Supply property. During the
file review it was noted that Plantation has also been directed by NCDENR, via a February 18, 2013 letter, to
conduct site assessment in response to the findings of the 2004 HD Supply property site assessment “to confirm if
groundwater contaminant plumes have migrated off site.”

An aerial photograph showing the HD Supply property, former Hess terminal, and Plantation facility is attached as
Exhibit B. The locations of the November 2004 temporary monitoring wells on the HD Supply property shown on
the aerial photograph are approximated based on the locations shown in the UES site map. In addition to the three
referenced facilities, the aerial photograph shows the approximate location of underground product pipelines,
operated by Plantation and others, situated between the former Hess terminal and HD Supply property.

Reports reviewed for the Plantation facility include annual groundwater monitoring reports from 2003 to 2012, and a
2005 Site Assessment Report, all prepared by CH2MHill. In addition to providing data and evaluations for the
specific monitoring/assessment events reported upon, the CH2MHill reports contain historical groundwater data and
evaluations for the Plantation facility. Reports reviewed for the former Hess terminal consist of a May 1, 1990
Phase I Hydrocarbon Assessment and July 27, 1990 Phase II Hydrocarbon Assessment, both prepared by Carolina
Geological Consultants, Inc. (CGS). No other site assessment reports for the former Hess terminal are on file at the
Guilford County EHD or known to exist. Because the existing referenced reports are readily available for review by
NCDENR and/or Guilford County personnel at the offices of the Guilford County EHD, report copies are not
provided with this letter.

Based on the review of historical reports and records on file at the Guilford County EHD, TransMontaigne is
respectfully declining to conduct site assessment to evaluate potential sources of groundwater COCs detected in the
November 2004 groundwater samples collected on the HD Supply property. Reasons for this conclusion are as
follows.

Groundwater potentiometric-surface contour maps for the Plantation facility from 2003 to 2012
consistently indicate a southwest direction of groundwater flow from the southwest corner of the Plantation
facility to the HD Supply property. For reference, a March 2004 potentiometric surface contour map
prepared for the Plantation facility by CH2MHill is attached as Exhibit C. The three temporary monitoring
wells on the HD Supply property with detected groundwater COC concentrations in November 2004
(TMW-1, TMW-2, and TMW-3) are downgradient of areas of documented groundwater contamination at
the Plantation facility. Only a small portion of the southeast corner of the former Hess terminal property,

PIEDMONT GEOLOGIC, P.C.
representing less-than approximately 3% of the entire Hess property, appears to be upgradient of temporary
monitoring wells TMW-2, TMW-3, and TMW-4, but not TMW-1. The latter monitoring well, which
(again) contained the highest groundwater COC concentrations in November 2004, appears to be
downgradient of only the Plantation facility and not any portion of the former Hess terminal. Only
temporary monitoring-well TMW-4, which had no detected groundwater COC concentrations in November
2004, would appear to be possibly downgradient of any petroleum storage/handling components at the
former Hess terminal.
Results of laboratory analysis of groundwater samples collected from former Hess terminal monitoring
wells in 1990 indicated the detection of MTBE in four monitoring wells (see former Hess terminal map,
from CGS, May 1990, attached as Exhibit D). MTBE was detected in March 1990 groundwater samples
from former Hess terminal monitoring-well MW-5 and MW-6 (3.94 ug/L and 23.6 ug/L), located along the
boundary between the former Hess terminal and Plantation facility, and in former Hess terminal
monitoring-well MW-1 (5 ug/L), located along the boundary between the former Hess terminal and HD
Supply property and in the downgradient direction of groundwater flow from MW-5, MW-6, and the
Plantation facility. The detection of MTBE in the 1990 groundwater samples from perimeter monitoring
wells MW-5 and MW-6, as well as downgradient monitoring-well MW-1, is consistent with encroachment
of a groundwater COC plume from the Plantation facility, as discussed further below. It is noted that the
former Hess terminal monitoring-well designations apparently were changed between the May 1990 and
July 1990 site reports prepared by CGS. For simplicity, the original well designations as indicated in the
May 1990 CGS report are referenced in this letter.
Results of laboratory analysis of March and July 1990 former Hess terminal groundwater samples for
BTEX indicated encroachment of a dissolved BTEX plume in groundwater from the adjacent and
upgradient Plantation facility (see former Hess terminal map from CGS, July 1990, attached as Exhibit E).
Historical groundwater benzene isoconcentration contour maps prepared for the Plantation facility by
CH2MHill, based on groundwater sampling/analysis events completed for the Plantation facility from 2003
to 2012 (see example from September 2003, attached as Exhibit F), also indicate encroachment of a site
groundwater COC plume from the Plantation facility to the southeast corner of the former Hess terminal
and, by extension, to the HD Supply property to the southwest. It is noted that no monitoring well
coverage has existed in the southwestern-most portion of the Plantation facility to delineate the potential
distribution of groundwater COCs between the Plantation facility and the eastern border of the HD Supply
property, such as where HD Supply temporary monitoring-well TMW-1 is located.
Historical results of groundwater analysis for Plantation facility monitoring-well PMW-9 (from CH2MHill
annual groundwater monitoring reports), located upgradient of HD Supply temporary monitoring-well
TMW-2, indicate that MTBE was detected during groundwater monitoring events from as early as 1995
(the oldest data reviewed in site reports) to as late as 2010, with the highest reported concentration of 180
ug/L being detected in 1997. Again, no Plantation facility monitoring wells exist directly upgradient of HD
Supply temporary monitoring-well TMW-1, which contained the highest detected MTBE concentration in
the November 2004 groundwater samples collected from the HD Supply property.

Finally, based on a review of the November 2004 report prepared by UES, the accuracy and representativeness of
the November 2004 groundwater analysis results for the HD Supply property are considered suspect. For instance,
the well installation descriptions in the report for the temporary monitoring wells indicate that the well annuli above
the sand packs were “backfilled” using drill cuttings from the monitoring-well borings, and that no bentonite seal
was emplaced on top of the sand pack. This well construction procedure is in violation of 15A NCAC 2C .0108
(Standards of Construction: Wells Other Than Water Supply), which states that a bentonite seal (or other material
approved by NCDENR), shall be installed in the monitoring-well annulus above the sand pack and that the
remaining well annulus above the seal shall be filled with grout. The HD Supply property is in an area of
Greensboro that has been industrialized for the past 70 years, and trace concentrations of petroleum constituents in
soil may be expected in various localities where fuels are handled/stored, or even where vehicle fleets are
maintained (such as historically at the HD Supply property). As a result, detections of petroleum compounds, such
as MTBE, which is relatively non-biodegradable compared to BTEX, could be expected for groundwater samples
collected from such improperly constructed monitoring wells. Furthermore, it is unclear, and again considered
suspect, as to why an approximately 9-year time lapse transpired between the time that the results of November
2004 groundwater analysis for the HD Supply property were received by the property owner and the time that these
results were provided to NCDENR (and/or Guilford County EHD). It is TransMontaigne’s assertion that the burden
of proof should be placed on the owner of the HD Supply property to: 1) confirm that the November 2004
groundwater sampling results are representative of actual site conditions; and, 2) demonstrate that detected
groundwater COC concentrations are not related to a source on the HD Supply property.

Based on the above evaluations, and as stated previously in this letter, TransMontaigne respectfully declines to
conduct any site assessment activities for the former Hess terminal until the existence of groundwater COCs at the
HD Supply property is confirmed, and all other more apparent potential sources of such groundwater COCs are
investigated and eliminated from further consideration.

On a related matter, it is noted that the February 18, 2013 letter to TransMontaigne references a NCDENR Incident
Number (85838). The origin of this incident number is puzzling as the most recent correspondence in the Guilford
County EHD files prior to the February 2013 letter, consisting of July 1993 letters to/from NCDENR and Amerada
Hess, specifically indicated that no groundwater incident number had been assigned to the site. Furthermore, the
July 1993 letter from Amerada Hess to NCDENR indicated that NCDENR had concluded at that time that no further
action was required for the site. No NCDENR correspondence regarding the former Hess terminal for the period
between July 1993 and February 2013, including any Notice of Violation (NOV) or Notice of Regulatory
Requirement (NORR), nor any other documentation of the reason/origin of the referenced incident number, is
contained in Guilford County EHD files. The incident number appears to have been assigned relatively recently
(i.e., within the past few years) based on incident numbers seen for other sites. TransMontaigne requests an
explanation of why the former Hess terminal has been assigned an incident number in light of the fact that no
“incidents” at the facility are documented and, in the absence of solid and legal justification to the contrary provided
by NCDENR, requests that the referenced incident number be eliminated in relation to the former Hess terminal and
that the terminal be removed from any associated lists or databases maintained by NCDENR and/or Guilford County
EHD.
