EXECUTIVE SUMMARY
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed system
operation and maintenance (O&M) and groundwater monitoring activities associated with the
soil and groundwater remediation system located at the Pilot Travel Center #56, a retail gasoline
station. In accordance with North Carolina Department of Environmental Quality (NC DEQ)
regulatory reporting requirements, Apex has prepared a Corrective Action Performance Report
for the subject property located at 2825 Lane Street in Kannapolis, North Carolina. This report
includes routine system O&M, system repairs, system monitoring, and semi-annual groundwater
sampling for the period beginning January 1, 2018 and ending June 30, 2018.
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
The objective of the Corrective Action Plan (CAP) was to maintain groundwater quality
conditions at the site below the applicable 2L Standards for benzene and meth tertbutyl ether
(MTBE) while aggressively remediating source area groundwater and minor soil contamination.
The corrective action approach to achieve the aforementioned goals for groundwater at the site
consisted of an engineered air sparging and soil vapor extraction (SVE) system coupled with
monitored natural attenuation. Air sparging will be effective to remove the volatile hydrocarbon
constituents, including MTBE from the groundwater. SVE will capture volatile organic vapors
from the subsurface and provide an increased pressure gradient to enhance the efficacy of the air
sparging. The end of active remediation will be determined when asymptotic conditions are
reached in dissolved hydrocarbon concentrations in groundwater or when the applicable 2L
standards have been achieved, or risk can be reduced.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 micrograms per liter (µg/L). The MTBE 2L limit of 20 µg/L
was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23,
MW-24, and DMW-3) prior to CAP implementation.
At the conclusion of 2nd Quarter 2018 CAP implementation only MW-23 exceeded the
benzene 2L CAP endpoint and MW-9, MW-23, and DMW-3 exceeded the MTBE 2L CAP
endpoint. Petroleum compounds have never been detected in any of the area potable water
supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the
gasoline plume is confined to the original source zone identified and described in both the CSA
and approved CAP. Based on the continued presence of benzene and MTBE above 2L
groundwater quality standards in several monitoring wells, Apex recommends continued
operation of the remediation system in accordance with the approved CAP.

1.0 INTRODUCTION
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed system
operation and maintenance (O&M) and groundwater monitoring activities associated with the
soil and groundwater remediation system located at the Pilot Travel Center #56, a retail gasoline
station. In accordance with North Carolina Department of Environmental Quality (NC DEQ)
regulatory reporting requirements, Apex has prepared a Corrective Action Performance Report
for the subject property located at 2825 Lane Street in Kannapolis, North Carolina (Figure 1).
This report includes routine system O&M, system repairs, system monitoring, and semi-annual
groundwater sampling for the period beginning January 1, 2018 and ending June 30, 2018. The
remediation system was installed by Apex in accordance with the NC DEQ-approved Corrective
Action Plan (CAP) to address the multiple -phase contaminants identified on the subject property.
A description of the remediation system design and function is presented in Section 2.0. A site
plan depicting pertinent features of the subject site and surrounding area is provided as Figure 2.
This report for system O&M at the Pilot #56 facility is being submitted to Mr. Brett Morris of
NC DEQ, on behalf of Pilot.
2.0 SITE HISTORY AND BACKGROUND
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
According to records reviewed by Apex, seven underground storage tanks (USTs) were
closed by removal in May 1994. The UST Closure Report also documented that two 12,000-
gallon USTs were removed from service in 1991. The report also documented that there were
releases associated with both product lines and the southern UST tank basin. The release was
assigned incident number 6379 by the North Carolina Department of Environment and Natural
Resources (NCDENR). The site was redeveloped and subjected to active remediation.
Following 18 months of active remediation, the incident was closed by NCDENR in 1998.
In April 2006, a contractor mobilized to the site to gauge monitoring wells prior to
abandonment on behalf of the responsible party for incident 6379. The contractor reportedly
discovered light non -aqueous phase liquid (LNAPL) in RW-8 and MW-9. Follow-up
investigation in the tank areas and product lines failed to determine a new source. NCDENR
considered the LNAPL to be a new release and assigned incident number 36096.
Several phases of assessment have occurred since 2006. A site check on the south side of
the facility was performed which focused on soils around the new UST basin and the dispenser
lines. A total of 22 soil samples were collected for total petroleum hydrocarbons (TPH)
gasoline -range organics (GRO) analysis. Nine of the 22 soil samples were analyzed for TPH
diesel -range organics (DRO) as well. Four soil samples were reported with GRO concentrations
CA Performance Report (Jan. 1 to June 30, 2018) 1 July 6, 2018
Pilot #56
Incident#36096

above the NCDENR UST action level of 10 milligrams per kilogram (mg/kg) at the time of the
investigation. DRO was detected in five of the soil samples above 10 mg/kg. A Phase II
Limited Site Assessment was conducted and submitted, and the site was assigned a "High Risk"
ranking by NCDENR. On February 20, 2009, NCDENR issued a Notice of Regulatory
Requirements requesting a Comprehensive Site Assessment (CSA) for the site.
A CSA was prepared for the site in December 2009 that delineated the dissolved -phase
groundwater contamination vertically and horizontally. An additional round of sampling
conducted in September 2010 confirmed the previous delineation. The dissolved -phase
hydrocarbon plume did not extend beyond the site property line and the detected groundwater
analytes did not exceed the gross contaminant levels (GCLs). The site is ranked `high risk' due
to the presence of water supply wells located within a 1,000-foot radius of the source area. It is
important to note that all the identified supply wells are located hydraulically cross -gradient of
the site and over 425 ft from any exceedances of the North Carolina 15A NCAC 2L groundwater
standards (2L). Repeated sampling and analysis of the water supply wells have never detected
petroleum hydrocarbons in the samples collected. Furthermore, there are three shallow sentinel
wells (MW-22, MW-26, and MW-27) between the source area and the water supply wells that
currently and/or historically have met 2L standards.
Silty sands dominate the lithology at the site. Shallow soil on site is disturbed and very
heavily compacted. Bedrock was encountered at approximately 45 ft below land surface (bls) at
DMW-2. Shallow groundwater is encountered at approximately 22 ft bls in the developed
portion of the site and flows to the north-northwest.
The contaminant of concern is unleaded gasoline. The two primary analytes of concern
are meth tertbutyl ether (MTBE) and benzene. Historically there were other exceedances of the
2L standard, but there were no 2L exceedances in wells without having either benzene or MTBE
present above 2L standards. The source area was presumed as south of the building, near MW-
24. At the time of CAP development the assumed dissolved groundwater contaminant plume in
the south area was approximately 150 ft long by 60 ft wide and 30 ft deep (20 to 50 ft bls). Mass
balance calculations indicated that the MTBE mass in the aquifer was approximately thirty
gallons and the benzene mass was approximately one gallon.
Based on the risk ranking for the site, corrective action objectives (CAOs) listed below
were established for each site media by NCDENR. The status of the site in achieving the
established CAOs are also noted. According to the North Carolina Administrative Code,
(NCAC) 15A 2L .0407 soil must be cleaned up to MSCCs for soil to groundwater or residential
standards, whichever is lower. The CAOs for residential soil were achieved prior to CAP
implementation. The remediation design in the CAP addressed the nominal soil contamination
in the southern area subsurface that remained above soil -to -groundwater standards. According to
NCAC 15A 2L .0202, surface water must be remediated to NCAC, 15A 2B standards (213). The
2B standard for benzene was 70 µg/L. The CAOs for surface water at the site were achieved
prior to CAP implementation and remedial measures were not carried forward in the CAP.
According to NCAC 15A 2L .0202, groundwater at the site must be remediated to the applicable
2L Standards which are 1.0 µg/L and 20 µg/L for benzene and MTBE, respectively.

Incident#36096

The objective of the CAP was to maintain groundwater quality conditions at the site
below the applicable 2L Standards for benzene and MTBE while aggressively remediating
source area groundwater and minor soil contamination. The corrective action approach to
achieve the aforementioned goals for groundwater at the site consisted of an engineered air
sparging and soil vapor extraction (SVE) system coupled with monitored natural attenuation. Air
sparging will be effective to remove the volatile hydrocarbon constituents, including MTBE
from the groundwater. SVE will capture volatile organic vapors from the subsurface and provide
an increased pressure gradient to enhance the efficacy of the air sparging. The end of active
remediation will be determined when asymptotic conditions are reached in dissolved
hydrocarbon concentrations in groundwater or when the applicable 2L standards have been
achieved, or risk can be reduced. A full description of the remediation system is provided below
in Section 3.0.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 µg/L. The MTBE 2L limit of 20 µg/L was exceeded in eight
monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3)
prior to CAP implementation. On December 12, 2017 Apex met with Department of
Transportation (DOT) staff and their consultant to inspect monitoring wells that were proposed
for abandonment during a road construction project at the site. As a result of the construction
project Apex turned off AS-5 supplying air to MW-18 pending abandonment by others.
Additional wells requiring abandonment for the construction project were MW-3 and MW-19.
At the conclusion of 2nd Quarter 2018 CAP implementation only MW-23 exceeded the benzene
2L CAP endpoint and MW-9, MW-23, and DMW-3 exceeded the MTBE 2L CAP endpoint.
3.0 REMEDIATION SYSTEM
The SVE and air sparge remediation system at the Pilot #56 facility was successfully
activated on April 18, 2012. The SVE system consists of a Roots Universal RAIV 36 blower
(replaced February 2017) paired with a ten horsepower Baldor Electric motor. Together the
system module is capable of a maximum extraction rate of 195 actual cubic feet per minute
(ACFM) at a vacuum of 12.0 inches of mercury (in Hg). The air sparge system consists of a 15
horsepower "rotary screw" compressor capable of 44-cubic feet per minute (CFM) at 55.0
pounds per square inch (PSI). The complete system is housed in a mobile eight foot by 16 foot
enclosed cargo trailer. The SVE manifold contains three "legs" capable of supplying a vacuum
at recovery locations SVE-1 through SVE-3. The remediation system layout with SVE well
locations is depicted on Figure 3. An air sparge manifold within the remediation system
enclosure includes individual gate valves, pressure gauges, pressure regulators, flow meters, and
check valves required to properly regulate air flow to allow for optimum treatment of the
identified subsurface petroleum constituents at air sparge points AS-1 through AS-16.
Activation activities included transportation of the turn -key system to the site and connection to
the sub -gradient infrastructure and separately metered power from other site activities. The
remediation system layout with air sparge well locations is depicted on Figure 4.

4,0 GROUNDWATER MONITORING
During this phase, Apex performed a semi-annual groundwater monitoring event to
assess water table elevations and current dissolved -phase contaminant levels. Pursuant to the NC
DEQ-approved CAP, Apex performed monitoring and sampling at monitoring wells MW-9,
MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and
DMW-3. On June 21, 2018, Apex used a SolinstTM electronic interface probe to investigate for
the presence of free product and to measure groundwater elevations. Free product was not
detected in any of the groundwater monitoring wells gauged during this phase. Groundwater
elevation data for the gauging event is presented in Table 1. Groundwater flow direction beneath
the site is influenced by water table depression and mounding created by system operation at the
recovery/sparge wells; thus, a water table gradient map is not included, but historical
groundwater flow direction has been measured to the north-northwest. Monitoring/recovery/air
sparge well locations are depicted on Figures 2, 3, and 4.
Per NC DEQ directives, on June 21, 2018, Apex collected groundwater samples from
twelve monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22,
MW-23, MW-24, MW-25, and DMW-3). Prior to sampling, Apex purged each well to remove
suspended sediment from the water column and to collect samples representative of aquifer
conditions. Each well was purged until a minimum of three well volumes had been displaced.
Groundwater samples were collected using dedicated, disposable, high -density polyethylene
bailers and were transferred directly into the appropriate sample containers immediately upon
collection. The samples were stored on ice pending delivery to the laboratory. Disposable, latex
gloves were used during all phases of sample collection. Groundwater samples were submitted
to ESC Lab Sciences (ESC) in Mount Juliet, Tennessee for volatile organic compound (VOC)
analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody
documentation were maintained during all phases of transport. Analytical results yielded
petroleum compounds in seven of the twelve monitoring wells sampled, with a maximum MTBE
concentration of 1,000 µg/L in monitoring well MW-23. A summary of current groundwater
quality data is presented in Table 2. Chain -of -custody documentation and the laboratory
Certificates of Analyses are included as Appendix A. Historical groundwater analytical results
are provided in Appendix B. The dissolved -phase endpoints for benzene of 1.0 µg/L was only
exceeded in MW-23 at 2.62 µg/L. The dissolved -phase endpoint for MTBE of 20 µg/L was
exceeded in monitoring wells MW-9, MW-23 and DMW-3, with a maximum exceedance of
1,000 µg/L in MW-23. Isoconcentration maps for benzene and MTBE are provided as Figures 5
and 6, respectively.
Per NC DEQ directives, on June 21, 2018, Apex also collected groundwater samples
from six supply wells (5922, 5925, 5927, 5955 Turkey Road and 2847 and 2865 Lane Street).
The supply well samples were collected from outdoor spigots after being purged for
approximately ten minutes. Clean, disposable latex gloves were used during all phases of sample
collection. The samples were labeled and stored on ice pending delivery to the laboratory.
Supply well samples were submitted to ESC for VOC analysis via U.S. EPA SW-846 method
6200B. Strict sample security and chain -of -custody documentation were maintained during all
phases of transport. Petroleum constituents were not detected in any of the supply well samples;
however, tetrachloroethene at a concentration of 1.24 µg/L was detected in supply well SW -
CA Performance Report (Jan. 1 to June 30, 2018) 4 July 6, 2018
Pilot #56
Incident#36096

5922, which was consistent with the previous sampling events. Tetrachloroethene is typically
associated with the use of solvents and could be the result of some recent plumbing repairs at the
residence. Historically petroleum compounds have not been detected in any of the supply wells.
The laboratory Certificate of Analysis and chain -of -custody records are provided as Appendix A.
5.0 OPERATION AND MAINTANENCE
Per NC DEQ directives, Apex performed monthly site visits during this phase for routine
O&M activities, system troubleshooting, system repairs, and system monitoring. The various
maintenance activities included adding lubricating oil and coolant to the air sparge system air
compressor, draining of moisture from the air compressor, greasing of all fittings associated with
the SVE blower and motor, replacement of faulty components, and other maintenance activities
to maintain system effectiveness. A tabular summary of the O&M dates and activities performed
is presented in Table 3. Copies of the O&M checklists are included as Appendix C. During this
phase, the SVE and air sparge system components achieved runtimes of 96% and 27%,
respectively. The air sparge compressor has been set to turn on and off as needed to maintain
proper flow rates at the manifold, so the runtime may not be reflective of the total delivery time
to the air sparge wells.
6.0 CORRECTIVE ACTION PERFORMANCE REPORT SUMMARY
Apex has completed CAP implementation activities associated with the Pilot #56 facility
located in Kannapolis, North Carolina for the period beginning January 1, 2018 and ending June
30, 2018. At the conclusion of 2nd Quarter 2018 CAP implementation only MW-23 exceeded the
benzene 2L CAP endpoint and MW-9, MW-23, and DMW-3 exceeded the MTBE 2L CAP
endpoint. Petroleum compounds have never been detected in any of the area potable water
supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the
gasoline plume is confined to the original source zone identified and described in both the CSA
and approved CAP.
Based on the continued presence of benzene and MTBE above 2L groundwater quality
standards in several monitoring wells, Apex recommends continued operation of the remediation
system in accordance with the approved CAP. System runtime remained consistent during this
phase. This report, prepared in accordance with NC DEQ-approved scope of work, is being
submitted to Mr. Brett Morris of NC DEQ on behalf of Pilot.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
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 radiochemical sample results for
solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet
weight was requested by the client. 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
ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
FP1
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.
Abbreviations and Definitions
FTC
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
FSS
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
[Cn]
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
FSr
(S)
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).
s
QC
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
FAI
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
FSC
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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
J
The identification of the analyte is acceptable; the reported value is an estimate.
J4
The associated batch QC was outside the established quality control range for accuracy.
