2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Post-Injection Groundwater Monitoring
Report for Former Conoco No. 33007 site (Phillips 66 RM No. 6189). This report documents the results of
a post-injection groundwater sampling event that was performed at the site in April 2023.

The former Conoco No. 33007 site address has historically been referenced as 2701 North Graham Street;
however, tax information for the subject site identifies the address as 2801 North Graham Street in
Charlotte, Mecklenburg County, North Carolina. In 1987, three 8,000-gallon gasoline USTs were removed
from the site. The USTs were replaced on November 3, 1987, with three 10,000-gallon gasoline USTs and
one 10,000-gallon diesel UST. A release was reported to the North Carolina Department of Environmental
Quality (NCDEQ) in 1994 during a property transfer. The UST system was removed from the site in 2016,
and the site is currently being redeveloped. The property is currently owned by Automotive Group, LLC.

On November 2-4, 2021, ATC performed a supplemental surfactant injection event and subsequent High
Vacuum Dual Phase Extraction (HVDPE) events. A post-injection groundwater monitoring event was
conducted at the site on November 23, 2021, to evaluate the immediate effectiveness of the injection /
HVDPE events. ATC submitted a Remedial Injection and Groundwater Monitoring Report to NCDEQ on
February 21, 2022, summarizing the injection/HVDPE events and subsequent groundwater monitoring
event. Based on the results of the groundwater monitoring event, ATC recommended a semiannual
sampling event be conducted in May 2022 to continue to monitor the effectiveness of the surfactant
injection.

A second post-injection groundwater monitoring event was conducted at the site on May 19, 2022, to
evaluate the effectiveness of the injection / HVDPE events. ATC submitted a Post-Injection Groundwater
Monitoring Report to NCDEQ on July 19, 2022, summarizing the second post-injection groundwater
monitoring event. Based on the results of the groundwater monitoring event, ATC recommended continued
sampling of the monitoring well network be conducted to monitor the effectiveness of the surfactant
injections.

On April 4, 2023, ATC mobilized to the site to conduct the third post-injection groundwater monitoring event
following the November 2021 injection/HVDPE event. Groundwater samples were collected from
monitoring wells MW-1, MW-2, MW-3, MW-4, MW-4D, MW-5, MW-7, MW-8, and MW-9 to be analyzed for
volatile organic compounds (VOCs) by Standard Method 6200B. Based on the laboratory analytical results,
benzene was detected at concentrations exceeding the established Gross Contamination Level (GCL) of
5,000 micrograms per liter (µg/L) in monitoring wells MW-3 (7,720 µg/L), MW-7 (15,600 µg/L), and MW-8
(5,640 µg/L). 1,2-Dichloroethane was detected at a concentration exceeding the established GCL of 400
µg/L in monitoring well MW-7 (625 µg/L). One or more dissolved petroleum constituents were detected at
concentrations exceeding the 15A NCAC 02L .0202 Groundwater Quality Standards (2L Standard) in
monitoring wells MW-3, MW-4, MW-5, MW-7, MW-8, MW-9 during the April 2023 monitoring event.

To achieve site closure, dissolved benzene concentrations must be below the GCLs. Based on the results
of the third post-injection groundwater monitoring event in April 2023, ATC concludes that the surfactant
injections have been generally successful in reducing benzene concentrations since the July 2019 pre-
injection sampling event. From July 2019 to April 2023 benzene concentrations have been reduced by
reduced by approximately 22% in MW-3, 81% in MW-4, 91% percent in MW-5, 52% in MW-7, and 43% in
MW-8. However, dissolved phase benzene concentrations remain above the GCLs in monitoring wells MW-
3, MW-7, and MW-8. ATC recommends semi-annual sampling of the monitoring well network to monitor
the effectiveness of the surfactant injections. Supplemental injection events may be proposed based on the
analytical results.

3.0 INTRODUCTION

ATC Associates of North Carolina, P.C. (ATC) was retained by Phillips 66 Company (Phillips 66) to provide
environmental consulting services at the Former Phillips 66 Risk Management (RM) Site No. 6189 (Incident
No. 12381). The site address has historically been referenced as 2701 North Graham Street; however, tax
information for the subject site identifies the address as 2801 North Graham Street in Charlotte,
Mecklenburg County, North Carolina. The site is currently being redeveloped and the former UST system
including dispensers and fuel island canopy were removed in 2016. A site topographic map is presented
as Figure 1, and a site map is presented as Figure 2. The scope of work summarized in this report includes
performance of an injection and extraction remedial event and post-remedial groundwater monitoring
activities. More details provided herein.

4.0 SITE BACKGROUND

The site is owned by Automotive Group, LLC. In 1987, three 8,000-gallon gasoline USTs were removed
from the site. The USTs were replaced on November 3, 1987, with three 10,000-gallon gasoline USTs and
one 10,000-gallon diesel UST. The UST system was removed from the site in 2016, and the site is currently
being redeveloped.

A release was identified in April 1994 during construction and assessment activities associated with product
line and dispenser upgrades. Thirteen soil samples were collected and analyzed for total petroleum
hydrocarbons (TPH). Additionally, approximately 25 tons of impacted soil were removed from the dispenser
and product line excavation.

A Preliminary Assessment was conducted in August 1994, prior to site ownership changing to Petro
Express. Soil analytical results from the assessment activities performed in 1994 indicated results above
10 milligrams per kilogram (mg/kg) for TPH of volatile and semi-volatile contaminant ranges. Ten of 13 soil
samples collected in 1994 had detected concentrations of TPH volatiles ranging from 41 mg/kg to 8,000
mg/kg and detected concentrations of semi-volatiles ranging from 200 mg/kg to 14,000 mg/kg.

Additional assessment phases were conducted during the period of 1999 until 2000, to satisfy requirements
of NCDEQ. Analytical results from 1999-2000 indicated petroleum impact in soil at concentrations that
exceeded the current Maximum Soil Contaminant Concentration Levels (MSCCs) in several soil samples.
It is noted that the analytical procedures at that time used laboratory method detection limits that exceed
the current MSCC levels, limiting interpretation of the historical data.

During a groundwater monitoring event on November 13, 2001, approximately 0.5 feet of light non-aqueous
phase liquid (LNAPL) was measured in well MW-3. Aggressive fluid vapor recovery (AFVR) events were
conducted at well MW-3 on January 17, 2002, and May 13, 2002. Approximately 62.5 gallons of LNAPL
and vapor were removed during the AFVR events. Statistical Inventory Reconciliation (SIR) reports, UST
system and line tightness test results, and leak detector results were obtained from the property owner for
October 2001, January 2002, and February 2002. According to the information obtained in the SIR reports,
the UST systems passed, and a new release was not identified.

Approximately 0.1 feet of LNAPL was measured in well MW-3 during a November 2002 groundwater
sampling event, and a petroleum absorbent sock was placed in well MW-3 to recover LNAPL. Semi-annual
groundwater monitoring reports were submitted for the site to NCDEQ (formerly NCDENR) from May 2001
through January 2003. A Corrective Action Plan was submitted by Delta Environmental Consultants on
August 1, 2003, recommending air sparge and soil vapor extraction (AS/SVE) as the proposed remedial
option. Based on funding levels for the NCDEQ UST Trust Fund, active remediation, other than AFVR
events, has not been requested for at the site.

Groundwater monitoring events were performed in 2006, 2012, 2013, and 2014 with groundwater impacts
consistently above Gross Contamination Levels (GCLs) in well MW-3. Petroleum impact in well MW-4
dropped below GCLs in 2013. ATC conducted a receptor survey and evaluation in June 2012, which
Former Conoco No. 33007 (RM No. 6189)
May 16, 2023

ATC Project No. P666189009 Phillips 66 Company
identified no surface water bodies or supply wells within NCDEQ-relevant distances. At the
recommendation of ATC, AFVR events have been conducted periodically between 2013 and 2016.

On September 8, 2015, the NCDEQ submitted a Notice of Regulatory Requirements (NORR) requesting
the installation of soil borings to evaluate soil conditions that may to be contributing to impaired groundwater
quality at the site. ATC submitted a report dated May 16, 2016, that identified soil impact in the vadose
zone in a soil boring located upgradient from well MW-3, which may be contributing to impaired groundwater
impact at the site. During the soil assessment efforts, four air sparge (AS) wells (AS-1 through AS-4) were
installed to assist with remedial efforts. Two AS wells were installed adjacent to well MW-3 and two were
installed adjacent to well MW-4.

In response to the May 16, 2016, Soil Assessment Report, which identified soil impact in boring SB-4 above
the Residential MSCC, the NCDEQ issued a NORR on May 20, 2016. The NORR indicated additional soil
assessment was required north of the northern dispenser area beyond soil boring SB-4 and that an
additional groundwater monitoring well was required. ATC was planning on submitting a preapproval
request for additional soil assessment and groundwater monitoring well installation in July 2016, however,
the property owner announced that they were closing the store and removing the USTs, lines and
dispensers from the site. Removal of the UST system was performed at the end of July 2016 by Southern
Pump and Tank Company (SPATCO) and closure sampling was performed by Environmental Compliance
Services, Inc. (ECS).

Following the UST system removal, Circle K #2723936 was granted a Notice of No Further Action (NFA)
on September 9, 2016, by the NCDEQ due to TPH being detected below the action levels of 50 parts per
million (ppm) for gasoline and 100 ppm for diesel in overburden soil samples collected during the UST
closure. The NFA indicated that pre-existing soil contamination from Conoco’s period of tank ownership
has been documented beneath Circle K’s tank system and that no release above TPH action levels is
attributed to Circle K’s tank system.

Based on this information, the NCDEQ issued a request to perform additional soil sampling to further define
areas of impacted soil at the site related to the former Conoco release. A Soil Assessment Report, dated
December 20, 2017, was submitted which identified soil impact that exceeds the Soil-to-Groundwater
MSCCs exists for multiple compounds across the site at various depths within the vadose and saturated
zones. The Residential MSCCs were exceeded for benzene in samples from borings SB-14, and SB-18
through SB-22 at various depths. Benzene impact above 1 mg/kg was identified within the vadose and
saturated zone samples from borings SB-5 near the former diesel dispenser island; at borings SB-5 and
SB-7 near the UST pit; and in samples from borings SB-12 through SB-22 located near the former gasoline
dispenser island. The report concluded that groundwater impacts appear to be the result of petroleum
constituents present in subsurface soil leaching to groundwater.

Following the soil assessment activities, ATC performed an updated groundwater monitoring event from
site monitoring wells. Based on field activities, observations, and groundwater analytical results from the
December 2017 groundwater monitoring event, ATC concluded the following: No LNAPL was measured in
the site monitoring well network; benzene was detected above the GCL of 5,000 ug/L in the groundwater
sample collected from well MW-3 at a concentration of 11,300 ug/L; groundwater impact by one or more
petroleum chemicals of concern was detected above the 2L Standards in monitoring wells MW-3, MW-4,
MW-5, and MW-6; and the groundwater flow at the site within the shallow aquifer is to the southeast across
North Graham Street, which is consistent with previous site information.

After review of assessment results, and site-specific characteristics, ATC recommended a remedial
injection pilot study using Ivey-sol®103 Blend Formulation (Surfactant), an in-situ, biodegradable surfactant
that is designed to desorb petroleum from soil allowing it to mobilize and be removed by conventional
extraction methods. The pilot study was approved for five, four-inch diameter Injection-Extraction Wells
(IEWs) across the center of plume mass near the northern dispenser island to conduct six Injection-
Extraction events. The area of impact was assessed using information collected from prior soil borings SB-
14, SB-20, SB-21, and SB-22, which showed high benzene impact in soil samples collected from the

saturated zone near the groundwater interface. Soil and groundwater impact also is present near the former
UST basin on the southern portion of the site, but pilot study efforts were focused on the larger portion of
the northern plume area to evaluate the remedial technique.

ATC performed the Pilot Study remedial evaluation, consisting of six injection and extraction events, at the
former Conoco #33007 facility (Phillips 66 RM No. 6189) located at 2701 North Graham Street in Charlotte,
North Carolina that consisted of six events between August 2019 and December 2019. Details of the pilot
study with comparative baseline and post-remedial groundwater monitoring results were provided in the
Remedial Pilot Study Report on March 23, 2020.

Following the initial pilot study and due to traces of surfactant still being present in monitoring wells at the
time of the post-pilot study monitoring event performed on January 29, 2020, ATC performed supplemental
8-hour AFVR events coupled with a freshwater injection to flush residual surfactant from the subsurface.
An updated groundwater monitoring event from the site monitoring wells was performed following the AFVR
events and the report was submitted on October 19, 2020.

An updated groundwater monitoring event from the site monitoring wells was performed on April 13, 2021.
A Groundwater Monitoring Report was submitted by ATC on July 30, 2021.

In November 2021, ATC performed a supplemental surfactant injection event and subsequent HVDPE
events. On November 2, 2021, a total of 1,375 gallons of surfactant mixture was injected at the site into the
five existing injection-extraction wells (IEW-1, IEW-2, IEW-3, IEW-4, and IEW-5). On November 3-4, 2021,
ATC returned to the site to perform the extraction events. Approximately 1,110 gallons of water were
removed on November 3, 2021, and 895 gallons were removed on November 4, 2021. A total of 2,005
gallons of groundwater were removed from the five injection-extraction wells during the HVDPE extraction
events. An estimated 9.46 gallons (59.12 pounds) of petroleum vapor were removed on November 3, 2021,
and 14.85 gallons (92.83 pounds) of petroleum vapor were removed on November 4, 2021, during the
HVDPE events. A combined estimated total of 24.31 gallons (151.95 pounds) of petroleum vapor were
removed during the HVDPE events.

On November 23, 2021, ATC conducted a groundwater monitoring event at the site to evaluate the
effectiveness of the injection/HVDPE event. Based on the groundwater analytical results from the
November 2021 event, benzene was detected above the Gross Contaminant Level (GCL) of 5,000 ug/L in
wells MW-3, MW-7, and MW-8 at concentrations of 9,070 ug/L, 16,800 ug/L, and 5,560 ug/L, respectively.
No other compounds exceeded their respective GCLs. Eight monitoring wells (MW-3, MW-4, MW-4D, MW-
5, MW-6, MW-7, MW-8, and MW-9) contained petroleum groundwater impact at or above the respective
2L Standards for one or more chemicals of concern. ATC recommended a semiannual sampling event in
May 2022 to continue to monitor the effectiveness of the surfactant injection.

On May 19, 2022, ATC mobilized to the site conduct the second post-injection groundwater monitoring
event following the November 2021 injection/HVDPE event. Based on the laboratory analytical results from
the May 2022 event, benzene was detected at concentrations exceeding the established GCL of 5,000 µg/L
in monitoring wells MW-3 (8,830 µg/L), MW-7 (13,700 µg/L), and MW-8 (6,080 µg/L). 1,2-Dichloroethane
was detected at a concentration exceeding the established GCL of 400 µg/L in monitoring well MW-7 (687
µg/L). One or more dissolved petroleum constituents were detected at concentrations exceeding their
respective 2L Standard in monitoring wells MW-3, MW-4, MW-5, MW-7, MW-8, MW-9 during the May 2022
monitoring event.

This report details the third post-injection groundwater monitoring event, conducted in April 2023.

5.0 GROUNDWATER CHARACTERIZATION

5.1 GROUNDWATER ELEVATION DATA

On April 4, 2023, ATC measured depth to groundwater from the site monitoring well network. Depth to
water was measured from the top of each well casing to the static water level using an electronic oil/water
interface probe. LNAPL was not encountered during the event.

The groundwater depths were converted to relative groundwater elevations using the top of well casing
elevation data reported from previous assessment reports. Monitoring well construction details are included
in Table 1. Table 2 provides the groundwater elevation data, as well as historical information for reference.
A groundwater elevation contour map is provided as Figure 3 based on the gauging data from the event.
The estimated groundwater flow direction within the shallow aquifer at the site is generally to the southeast
across North Graham Street, which is consistent with previous interpretations.

5.2 GROUNDWATER QUALITY

ATC collected groundwater samples from the site monitoring well network on April 4, 2023. Groundwater
samples were collected using disposable polyethylene bailers. Prior to sampling, a three-volume well purge
was performed. The groundwater samples were placed into appropriate laboratory-supplied containers,
properly labeled, and preserved on ice. The groundwater samples were shipped under chain-of-custody to
North Carolina-accredited SGS North America, Inc in Orlando, FL for analysis of VOCs by Standard Method
6200B, including benzene, toluene, ethylbenzene, and xylenes (BTEX), methyl tertiary butyl ether (MTBE),
ethylene dibromide (EDB), isopropyl ether (IPE), and naphthalene.

Based on the laboratory analytical results, benzene was detected at concentrations exceeding the
established GCL of 5,000 µg/L in monitoring wells MW-3 (7,720 µg/L), MW-7 (15,600 µg/L), and MW-8
(5,640 µg/L). 1,2-Dichloroethane was detected at a concentration exceeding the established GCL of 400
µg/L in monitoring well MW-7 (625 µg/L). One or more dissolved petroleum constituents were detected at
concentrations exceeding the 2L Standards in monitoring wells MW-3, MW-4, MW-5, MW-7, MW-8, and
MW-9 during the April 2023 monitoring event. A copy of the laboratory analytical report is included in
Appendix A. The April 2023 analytical results are summarized in Table 3, and historical groundwater
analytical results are presented in Table 4 for reference. A dissolved benzene concentration map from the
April 2023 event is included as Figure 4. A comparison of the current groundwater results to the November
2021 and May 2022 post-injection results and the July 2019 pre-injection results is included in Table 5.
Overall, reductions in Total BTEX ranged from approximately 23% in MW-8 to approximately 86% in MW-
5 when comparing the July 2019 data to the April 2023 data. Total BTEX increased by approximately 9%
in monitoring well MW-9 when comparing the July 2019 data to the April 2023 data. Naphthalene showed
an increase in the samples from wells MW-3, MW-5, MW-7, and MW-8 but a decrease for wells MW-9 and
MW-4. MTBE decreased in most monitoring wells but increased in MW-9. Concentration versus time graphs
for MW-3, MW-7 and MW-8 are presented as Figure 5.

6.0 CONCLUSIONS AND RECOMMENDATIONS

ATC performed a third post-injection groundwater monitoring event following the November 2021 surfactant
injection/HDVPE extraction events at the former Conoco #33007 facility (Phillips 66 RM No. 6189) located
at 2701 North Graham Street in Charlotte, North Carolina. Based on field activities, observations, and
groundwater analytical results from the April 2023 post-injection groundwater monitoring event, ATC
concludes the following:

 LNAPL was not measured in the site monitoring well network during the event;

 The groundwater flow at the site within the shallow aquifer is generally to the southeast across North
Graham Street, which is consistent with previous site information;

 Benzene was detected above the GCL of 5,000 ug/L in the groundwater samples collected from
monitoring wells MW-3, MW-7, and MW-8 at a concentrations of 7,720 ug/L, 15,600 ug/L, and 5,640
ug/L, respectively;

 1,2-Dichloroethane was detected above the GCL of 400 ug/L in the groundwater sample collected from
monitoring well MW-7 at a concentration of 625 ug/L;

 Groundwater impact by one or more petroleum chemicals of concern was detected above the 2L
Standards in monitoring wells MW-3, MW-4, MW-5, MW-7, MW-8, and MW-9;

 A comparison of the analytical data from the July 2019 pre-injection event to the April 2023 second
post-injection event indicates decreased benzene, total BTEX, MTBE, and naphthalene concentrations
in all monitoring wells with the exception of benzene, total BTEX, and MTBE in MW-9 and naphthalene
in MW-3, MW-7, and MW-8, which indicated increasing concentrations. Naphthalene has a higher
sorption to soils that makes it slower to liberate and recover.

To achieve site closure, dissolved benzene concentrations must be below the GCLs. Based on the results
of the third post-injection groundwater monitoring event in April 2023, ATC concludes that the surfactant
injections have been generally successful in reducing benzene concentrations since the July 2019 pre-
injection sampling event. From July 2019 to April 2023 benzene concentrations have been reduced by
approximately 22% in MW-3, 81% in MW-4, 91% percent in MW-5, 52% in MW-7, and 43% in MW-8.
However, dissolved phase benzene concentrations remain above the GCLs in monitoring wells MW-3, MW-
7, and MW-8. ATC recommends continual sampling of the monitoring well network to monitor the
effectiveness of the surfactant injections. Supplemental injection events may be proposed based on the
analytical results.

7.0 REPORT LIMITATIONS

This investigation is intended to be a non-biased assessment of on-site environmental conditions proximal
to the location of the former and/or current UST system. Subsurface investigative and remedial
methodologies were performed in general accordance with applicable state and federal regulatory
requirements. The information presented in this report is based upon site-specific observations, generally
accepted geological and environmental consulting practices, and analytical results for environmental
samples collected at the time the field investigation was performed. The data presented in this report are
believed to represent subsurface conditions at the facility; however, data may not be completely
representative of subsurface conditions at every location. ATC assumes no liability arising from
environmental impact to, or from, the site, regardless of the date of impact occurrence or findings.
