EXECUTIVE SUMMARY
On behalf of ExxonMobil Environmental and Property Solutions Company (E&PS), Arcadis G&M
of North Carolina, Inc. (Arcadis) is proposing to complete a Pilot Test onsite at the Former
ExxonMobil Facility #45552 located at 1920 Four Seasons Boulevard, Hendersonville, Henderson
County, North Carolina (the Site). The Pilot Test is being conducted to expedite removal of
contaminants and closure of the Site. This work plan is being submitted for the pilot testing of a
full-scale air sparge/soil vapor extraction (AS/SVE) system to address remaining soil and
groundwater above the Title 15A of the North Carolina Administrative Code (NCAC) Gross
Contaminate Levels (GCL) standards.

1 SITE CONDITIONS & CHARACTERIZATION
Former ExxonMobil (Exxon) facility #45552 located at 1920 Four Seasons Boulevard,
Hendersonville, Henderson County, North Carolina currently operates as a retail gas station
owned and operated by Henderson Oil Company, Inc. A petroleum release was discovered in
1992 and multiple cleanup techniques have been implemented to remediate the release. This pilot
test work plan was developed to test the feasibility of AS/SVE to expedite Site cleanup.
NCDEQ Risk Classification for the site is “Intermediate/Commercial” due to dissolved phase
constituents exceeding gross contamination level standards for groundwater. A site location map
is presented as Figure 1 and a site map is shown as Figure 2.
1.1 PREVIOUS AS/SVE REMEDIATION
Soil vapor extraction/air sparging (SVE/AS) remediation was initiated at the Site in January 1995 and
initially operated until July 1996 when the passage of Senate Bill 1317 temporarily suspended remediation
requirements for low priority sites. The system was restarted in June 1998 and was operated until August
2003 when it was permanently shutdown in response to the passage of House Bill 897.
The operational set points were reported to the NCDEQ in a October 1993 Correction Action Plan
(Dames & Moore, 1993) and indicated the following AS/SVE parameters:
• SVE System - Vacuum of 100 inches of water column (“wc) and a flow rate of 50 standard
cubic feet per minute (scfm) resulted in a radius of influence of over 22 feet (0.4 inches of
water column (“wc) induced vacuum influence), and
• AS System - A flow rate of 4 scfm and a pressure just above the hydrostatic pressure
(approximately 0.43 psi/foot of water column) resulted in a radius of influence of up to 22
feet (1 milligram per liter (mg/L) dissolved oxygen increase observed).
The 1993 pilot test was used as the design basis for the radius of influence for the proposed pilot
test. The assumptions listed above will be confirmed during the proposed pilot test along with
confirming concentration reductions in the proposed AS/SVE area.

2 PILOT TEST WORK PLAN
2.1 OBJECTIVES
The objectives of the AS/SVE pilot test are to implement a 180-day AS/SVE pilot test on an
impacted portion of the property southwest of the existing pump islands to determine the
feasibility of AS/SVE to reduce groundwater concentrations in monitoring wells MW-9, MW-10,
MW-11 and INJ-2. A Notice of Intent (NOI) to operate or install injection wells permit will be
submitted to the North Carolina Department of Environmental Quality (NCDEQ) – Division of
Water Resources (DWR) - Underground Injection Control (UIC) Program at least two weeks
before AS/SVE pilot activities. Following well installation activities, an injection event record (IER)
and well construction record (GW-1) will be submitted to the DWR-UIC Program within 30-days of
completion.
Arcadis is proposing to install four new air sparge (AS) wells and three new soil vapor extraction
(SVE) wells. Each of the new AS/VE wells will be installed and conveyance piping installed
below grade to an AS/SVE pilot test system proposed to be located behind the current station
building (Figure 3). The proposed air sparge and soil vapor extraction (AS/SVE) pilot test will be
conducted over a 180-day period following startup testing. The first day of startup testing will be
dedicated to setting up the pilot test equipment and step testing, while the second day will be
used to evaluate the effect of AS/SVE for a period of 8 hours. After the first two days of startup
testing, the AS/SVE pilot test equipment will be left in operation for a period of 180-days to
determine the long-term effect of AS/SVE. Monthly site visits will be conducted over the 180-day
period to evaluate the operational settings on a month to month basis. The locations of the
proposed AS and SVE wells are presented in Figure 3. At the conclusion of the pilot test, Arcadis
will evaluate the AS/SVE radius of influence (ROI), pressures, and vacuums and will submit a
letter report to the NCDEQ for review and approval summarizing the results of the proposed pilot
test.
Arcadis recognizes the complexities involved in performing an air sparge and soil vapor extraction
pilot test. With this in mind, flexibilities have been built into this pilot test to allow for modifications
to the procedure during the test, based upon actual conditions encountered in the field. These
flexibilities are presented as contingencies and are discussed in Section 2.7.
Construction drawings are presented in Appendix A, and include additional information on piping
layout, trench layout, process and instrumentation diagrams (P&ID), AS/SVE manifold details,
and service entrance details.
2.2 PILOT TEST CONFIGURATION
The location of the proposed AS and SVE wells are shown on Figure 3. This location was
selected to address the presence of elevated groundwater constituents of concern (COCs) in this
area. Arcadis is assuming a 20-foot radius of influence for the AS system and a 25-foot radius of
influence for the SVE system for the pilot test. The influence from both the AS and SVE system
will be confirmed during testing.

The air sparging test will utilize four AS wells (AS-1 through AS-4) to be installed using hollow
stem auger drilling equipment and constructed with 2-ft. (35 to 37 ft. below ground surface (bgs))
of 2-inch diameter schedule 40 polyvinyl chloride (PVC) 0.010-inch slotted well screen. The
proposed AS wells will be housed in a flush-mount 12-inch diameter bolt-down well vault. The
typical AS well diagram is included as Figure 4.
The SVE portion of the test will utilize three soil vapor extraction wells (SVE-1 through SVE-3) to
be installed using hollow stem auger drilling equipment and constructed with 10-ft. (10 to 20 ft
bgs) of 4-inch diameter schedule 40 PVC 0.020-inch slotted well screen. The proposed SVE
wells will be housed in a flush-mount 12-inch diameter bolt-down well vault. The typical SVE well
diagram is included as Figure 4.
Also included as part of the pilot test is three vapor monitoring points (VMPs) located on the
perimeter of the AS/SVE influence area to monitor for potential vapor buildup. The VMP (VMP-1
through VMP-3) will be installed using hollow stem auger drilling techniques, constructed with 10
feet of 1-inch diameter schedule 40 PVC 0.010-inch slotted well screen flush threaded to 10 feet
of 1-inch diameter schedule 40 PVC riser pipe. The VMP screen length and depth will match the
SVE wells. The proposed VMP will be installed in a flush-mount 8-inch diameter bolt-down well
vault.
To determine influence during pilot testing, four existing monitoring wells (MW-3R, MW-9, MW-10
and MW-11) and three VMPs (VMP-1 through VMP-3) will be used as observation wells and will
be monitored during the testing. The observation wells are located approximately 4 ft. (MW-10), 5
ft. (MW-11), 8 ft.(VMP-2), 8 ft. (MW-9), 10 ft. (VMP-3), 28 ft (VMP-1) and 40 ft.(MW-3R) from the
closest AS/SVE pilot test wells. During the first two days of startup testing, each well will be
monitored hourly for vacuum influence, depth-to-water, and dissolved oxygen. VMP-1 through
VMP-3 will be monitored for vacuum influence and organic vapor analyzer (OVA) readings hourly
during the testing. Following the initial startup, each well will be monitored on a monthly basis.
A mobile AS/SVE unit will be used for the pilot testing activities. The AS and SVE systems will
each include a manifold with a pressure regulator or valve, pressure or vacuum gauge, and an air
flow measuring sensor for each AS and SVE well. The AS system will include a timer to cycle
the system on and off, similar to the previous onsite system. Arcadis intends to install new
conveyance piping below grade (air supply and vacuum lines) from the newly installed AS and
SVE wells to the mobile system behind the current facility building. The AS wells will be
connected into two zones (two wells per zone) and the SVE system will be connected in one
zone. The AS system will be operated in a pulsed/cycled mode operating two wells at a time
during the pilot test. The cycle frequencies will be determined during the pilot testing. The SVE
system will be connected in one zone and be designed to operated continuously. A new power
drop will be installed and the mobile AS/SVE system will be placed behind the current station
building (Figure 3).
The mobile AS/SVE system will consist of a moisture separator to capture any condensate,
vacuum blower, air compressor with a timer, and an AS/SVE manifold to regulate the
vacuum/pressure to each well. Additionally, the AS/SVE system will include fail safes so the AS
system cannot operate without the SVE system.

The AS system will be capable of providing up to 20 scfm of airflow at an applied pressure of up
to 23 psig per zone and the SVE system will be capable of a 150 scfm (230 acfm) flow rate at a
net system vacuum requirement of approximately 9.1 inches of mercury (“Hg) or 125 inches of
water column (“wc). Friction loss calculations are included in Appendix B. The calculations
account for the maximum flow rates and vacuums/pressures for the AS/SVE wells farthest from
the mobile equipment proposed for the AS/SVE systems. A 10% factor of safety is also included
in the friction loss calculation estimate. No vapor emissions treatment is proposed to be
conducted during the 180-day pilot test.
2.3 PILOT TEST MONITORING
Dissolved oxygen, inducted monitor well vacuum, and depth to water will be monitored from
monitoring wells MW-3R, MW-4, MW-9, MW-10, and MW-11 during pilot testing. Vapor
monitoring points VMP-1, VMP-2, and VMP-3 will be monitored for induced vacuum influence and
organic vapor analyzer (OVA). An increase in dissolved oxygen of 1 mg/L above static will be
considered AS influence and a vacuum increase of 0.10 “wc will be considered SVE influence.
Vapor emissions from the SVE system will be monitored using an OVA calibrated with hexane
standards. OVA samples will be collected during each site visit to monitor emissions and mass
removal rates. During the initial two-day startup testing of the AS/SVE systems, OVA samples
will be collected hourly from the effluent side of the SVE blower.
2.5 STEP TESTING
The proposed step test will consist of two air flow steps for the AS system and two steps for the
vacuum test for the SVE system. The objective of the step testing is to determine the optimal AS
and SVE flow rates, pressure, and vacuum to set up the AS/SVE system for the longer 180-day
test.
At the beginning of the step testing, the SVE system will be operated at vacuum of 5 “Hg for one
hour and then increased to 7” Hg during the 2nd hour. The objective of the SVE step test is to
determine the maximum radius of influence the SVE system can achieve. The flow rate, vacuum
influence, and FID reading will be collected hourly during the step test to determine the optimum
setting to operate the SVE system.
Following the SVE testing, the AS system testing will begin with the SVE system still in operation
at the determined optimum setting. The two AS air flow steps proposed are 5 scfm and 10 scfm.
Each step will be conducted for a period of two hours. The objective of the AS step testing is to
determine the optimal air flow rate and pressure. The limiting factors during the step testing will
be the maximum injection pressure and the pressure observed at nearby observation wells.
Based upon the previous onsite AS testing and depth below the water table, the maximum
proposed pilot test injection pressure is 30 psig and maximum observation wellhead pressure is 2
psig at wells within close proximity to operating AS wells (MW-9, MW-10, and MW-11). If
pressures are observed at the VMPs at any point during the pilot testing, the test will end until an
injection pressure/flow rate can be achieved with capture (negative wellhead readings) at the
VMPs. If the maximum pressures are reached in either the AS wells or observation wells, the
March 12, 2019

step test will end, and the pilot test will continue at a flow rate that allows for an injection pressure
below 30 psig and an observation well pressure below 2 psig.
2.6 PILOT TESTING
The following day after step testing, the data will be evaluated and a vacuum, flow rate, and
injection pressure will be selected to conduct an 8-hour test. The purpose of the 8-hour AS/SVE
test is to determine and evaluate the potential operating conditions for the longer term 180-day
pilot test. The SVE system will be operated at least 1 hour prior to initiating the AS system to
establish capture by the SVE system prior to air injection. Following the 1 hour of SVE operation,
the AS system will be operated at the parameters determined in the step test. The AS system is
proposed to be operated in a pulsed mode of one hour on and one hour off per zone or 4 hours of
total runtime per zone during the 8-hr test. Monitoring of the 8-hr pilot test will be conducted
hourly.
Following the 8-hr test, the system will be setup to operate continuously for the next 180-days.
During each monthly visit Arcadis will evaluate the current remediation system operational
settings on a month to month basis to maximize the AS/SVE effectiveness.
2.7 CONTINGENCIES
Contingencies may be required to allow for flexibility in performing the pilot test based upon
actual conditions encountered in the field. These contingencies include:
• Modifying the location of the AS and SVE wells depending on conditions observed in the
field,
• Modify the location of the trenching based upon conditions observed in the field;
• Operating the air injection in a shorter or longer pulsed mode in an attempt to increase
the radius of influence and reduce the injection pressure, and
• Increasing/reducing the length of the pilot test to achieve sufficient data to determine
operational set points,
2.8 GROUNDWATER MONITORING
Groundwater samples will be collected from MW-3R, MW-9, MW-10, and MW-11 quarterly during
the pilot test. The first sampling event will be conducted at 90-days and the second event will be
following the 180-day pilot test. A minimum of one week of AS/SVE system shut down is
proposed to allow the groundwater to stabilize prior to collection of groundwater samples. The
groundwater samples will be collected using disposable polyethylene bailers and new nylon rope.
Groundwater samples collected from the monitoring wells will be placed in laboratory-supplied
containers and shipped on wet ice to Eurofins Lancaster Laboratories in Lancaster, Pennsylvania
for analysis of volatile organic compounds (VOCs) by Standard Method (SM) 6200B. The results
of the groundwater sampling will be included in the pilot test report, described in the following
section.

3 REPORTING
At the conclusion of the AS/SVE pilot test, Arcadis will submit a letter report to the NCDEQ for
review and approval summarizing the results of the pilot test and the groundwater monitoring
results. A recommendation on the path forward will be included in the pilot test report.

The design basis for the calculations presented here is the use of the Darcy equation, which is commonly used to calculate
the frictional energy loss for incompressible fluids and compressed gases. The fluid or gas must not be moving too fast
(i.e., less than Mach 0.3), and be incompressible. The fluid is assumed incompressible if the pressure (density) change
along the section of interest is less than 10% of the starting pressure.
The Reynolds number and Darcy equation are written in terms of the constant mass flow rate per area, G, instead of velocity, v,
which varies with density and pressure changes. The ideal gas law can be combined with the Darcy equation to yield the
following equation.
where,PU = upstream pressure (psfg)
PD = downstream pressure (psfg)
f = Darcy friction factor (dimensionless)
L = length of pipe (ft)
G = mass flow rate per unit area (lbm/ft2-s)
R* = Universal Gas Constant (ft-lbf / lbmol-R)
T = temperature (°R)
D = pipe diameter (ft)
gc = gravitational constant (lbm-ft/lbf-s2)
MW = molecular weight (lbm/lbmol)
In order to determine the Darcy friction factor (f), the Reynolds number and relative roughness must be calculated. The
Reynolds number and releative roughness are calculated as follows.
where,Re = the Reynolds number, given by the following equation:
 = absolute viscosity (lbf-s / ft2)
= Darcy Friction Factor (Appendix 17.B)
where, relative roughness =
= specific roughness coeffient (Appendix 17.A)
Additional losses must be calculated for fittings and system operating units. The equivalent pipe lengths
are used to determine the head loss due to various fittings. Fitting loss coefficients (K) were obtained from
"Practical Hydraulics for the Public Works Engineer". The equivalent length (L) is determined from
the following equation:
