Dear Ms. Campbell:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
LINDA CULPEPPER
Interim Director
Reference is made to your request for rescission of the subject permit located at Former ExxonMobil Retail
Facility #42094 in Mecklenburg County NC. Staff from the Mooresville Regional Office has agreed that
a permit is no longer required. Therefore, in accordance with your request, In -Situ Groundwater
Remediation Permit WI0300192 is rescinded, effective immediately.
If in the future, you wish to operate a IN -Situ Groundwater Remediation system, you must first apply for
and receive anew permit. Operating an injection system without a valid permit may result in the assessment
of civil penalties and/or the use of other enforcement mechanisms available to the state.
If it would be helpful to discuss this matter further, please do not hesitate to call Shristi Shrestha at
[phone].
Sincerely,
Linda Culpepper, Interim Director

C. INCIDENT DESCRIPTION
1. Describe the source of the contamination: Underground Storage Tanks (USTs) onsite stored unleaded gasoline
heating oil, and used motor oil at the above site. In 1990 the property was divested by Exxon and the USTs and
ancillary components were removed. Petroleum impacted soil was discovered during UST removal activities at
the base of the UST pit and beneath one dispenser island. Soil and groundwater samples collected in 1990
indicated that volatile hydrocarbon contamination present in the soil was in contact with groundwater at the site
The amount and cause of the release is unknown. The site facilities were demolished and USTs closed by removal
in 1990. The site is currently operating as a vehicle repair facility.
2. List all contaminants present in soils or groundwater at the site (contaminants may be listed in groups, e.g.,
gasoline, diesel, jet fuel, fuel oil, chlorinated ethenes, chlorinated ethanes, metals, pesticides/herbicides, etc):
Soil: volatile hydrocarbons
Groundwater: volatile hydrocarbons
3. Has LNAPL or DNAPL ever been observed at the site (even if outside the injection zone)?
((Es If yes, list maximum measured separate phase thickness Historical maximum thickness of 0.53 feet in
MW-1 on October 10, 2008. Last NAPL detection was on October 6, 2011 in MW-9 at a thickness of 0.73 feet.
( No If no, list maximum concentration of total VOCs observed at site:
The most recent sampling event on October 6, 2011 indicated dissolved -phase concentrations of benzene (31.800
ppb), 1,2-dichloroethane (1,710 ppb), and EDB (136 ppb) which exceed the applicable North Carolina Gross
Contamination Levels (GCLs) standards. Tetrachloroethylene, a constituent associated with dry cleaning releases
was detected in MW-7 at a concentration of 2,300 ppb and exceeds the applicable North Carolina GCL standard.

2.0 Site History
Former ExxonMobil (Exxon) facility #42094 located at 3721 Freedom Drive, Charlotte,
Mecklenburg County, North Carolina operated as a gasoline retail store and service
station between 1970 and October 1990. All underground storage tanks (USTs) and
ancillary equipment was closed by removal in November 1990 prior to divestment of
the site by Exxon. The UST system consisted of one 6,000-gallon gasoline UST, two
4,000-gallon gasoline USTs, one 4,000-gallon used oil UST and one 550-gallon
heating oil UST. The site was re -developed as a vehicle repair facility between 1993
and 2001.
Petroleum -affected soil was discovered during the November 1990 UST closure at the
base of the gasoline UST field and below one dispenser island. The cause and
quantity of the release is unknown. A soil -vapor extraction (SVE) system utilizing two
extraction wells operated intermittently at the site between August 1992 and July
1996. Additional soil samples were collected by Environmental Resources
Management Inc. (ERM) in the vicinity of the former gasoline UST field, eastern
dispenser island and former used oil UST in 2001 and 2002. Petroleum affected soil
has been documented beneath the former gasoline UST and dispenser island.
Concentrations of 19 volatile organic compounds (VOCs) above soil -to -ground water
Maximum Soil Concentrations (MSCCs), but below the applicable
industrial/commercial MSCCs, were detected in 2001 and 2002 soil samples. Four
VOCs (benzene, naphthalene, C5-C8 Aliphatics and C9-Cl2 Aromatics) were detected
in concentrations above the residential MSCCs.
The bulk of petroleum -affected soil is located between 11 and 15 feet below ground
surface in the capillary fringe above the water table. The petroleum -affected soil within
the capillary fringe, in areas away from the former UST field and dispenser island, is
attributed to the migration of petroleum -affected ground water beneath the site. The
smear zone left by the petroleum -affected ground water across the capillary fringe is
suspected to be the source of the petroleum -affected soils at depths across much of
the site.
The site is owned by Mr. Robert Morris and currently operates as a vehicle repair
facility. The area surrounding the site is composed of commercially developed
properties, mixed -use properties and residential properties. The nearest single-family
residence is located approximately 130 feet west of the source area. ERM conducted a
water supply well survey for the site in February 2001. Five inactive water supply wells
have been identified within a 1,500-foot radius of the site. All wells are located

northwest and topographically upgradient of the subject property. The nearest well is
located approximately 1,350 feet from the source area. Municipal water service
provided by the Charlotte -Mecklenburg Utilities Department is available to all properties
in the surrounding area. No surface water bodies have been identified within 500 feet
of the site.
The site is located within the Charlotte geologic belt of the Piedmont physiographic
province and is underlain by saprolite, a layer of weathered and variably decomposed
bedrock. Soils at the site consist primarily of silt and clay based on soil boring logs for
site monitoring wells and direct push soil borings. Saprolitic soil was encountered in all
borings at depths greater than 10 feet below ground surface (bgs). Imported fill soil
consisting of semi -plastic clay with gravels was observed over much of the site.
Partially weathered bedrock was encountered in soil borings at 22 feet and 55 feet
below ground surface. Depth to groundwater at the site, on average, ranges from 11 to
28 feet bgs.
The North Carolina Department of Environment and Natural Resources (NCDENR)
Risk Classification for the site is "Intermediate" due to the presence of free product and
exceedances of the groundwater Gross Contamination Levels (GCLs) for benzene,
naphthalene, C5-C8 aliphatics and C9-Cl2 aromatics.
A site location map is presented in Figure 1 and a site map is shown as Figure 2.
3.0 Hydrogeologic Description
Site topography is relatively flat with minimal topographic relief. Drinking water in the
area is provided by the Charlotte -Mecklenburg Utility Department (CMUD) which is
located approximately 15 miles northeast of the site. The source of CMUD drinking
water, Mountain Island Lake Reservoir, is not hydraulically connected to the site.
Well construction data is presented in Table 1. Current and historical groundwater
elevations measured in the site monitoring wells are presented on Table 2. A
potentiometric surface map is provided as Figure 3. Historical groundwater elevation
data obtained during previous groundwater gauging events indicate the shallow
groundwater flows generally to the southeast with a horizontal gradient of
approximately 0.01 feet per year (ERM, 2002). Cross section maps of the site are
presented as Figures 8A — 8C.

3.1 Regional Geology and Hydrogeology
Former ExxonMobil facility #42094 in Charlotte is located in the Piedmont
physiographic province of North Carolina. The site lies within the upland section of the
Piedmont province which is characterized by rolling hills. The site lies at an elevation of
about 790 feet above mean sea level. Saprolite, a zone of weathered and variably
decomposed bedrock, commonly mantles bedrock in this region. Saprolite has the
appearance of compact clayey to sandy soil with the original bedrock textures and
features preserved. Saprolite is created through the chemical weathering of bedrock
over a long period of time in areas of limited erosion.
The city of Charlotte is underlain by granitic plutons and metamorphic volcanic
sediments within the Charlotte geologic belt according to the Geologic Map of North
Carolina (1985) and Goldsmith, et. al. (1988).
3.2 Site Geology and Hydrogeology
Native soils at the site consist primarily of silt and clay based on soil boring logs.
Saprolitic soil was encountered at depths greater than 10 feet. Imported fill soils
consisting of semi -plastic sandy clay with gravels were observed over much of the site.
The sill soil did not extend greater than 10 feet below ground surface (bgs). Partially
weathered bedrock was encountered in borings for wells MW-7 and DW-1 at depths of
18 and 47 feet bgs, respectively. Competent bedrock was encountered in these two
borings at 22 feet bgs and 55 feet bgs, respectively.
4.0 Injection Fluid Composition
The proposed injection fluid will be composed of potable water from the CMUD, mixed
with Biosolve® Surfactant, a NCDENR approved injectant, to a maximum
concentration of 6% volume of surfactant/volume of water. A Material Data Safety

Sheet (MSDS) and Product Description for Biosolve® Surfactant are included as
Appendices A and B.
5.0 Injection Rational
The goal of the planned remediation injections is to eliminate periodic free product and
concentrations of dissolved -phase chemicals of concern (COC) at monitoring wells
MW-5 and MW-9 to below the applicable North Carolina Gross Contaminant Levels
(GCLs). The surfactant application will not likely achieve all groundwater standards
immediately, but the intent is to significantly reduce concentrations to levels that will
allow natural attenuation to achieve groundwater standards in a reasonable timeframe.
Under the proposed approach, active remediation would be conducted via in -situ
injection of surfactant to the target monitoring and injection wells. A non-ionic or
anionic surfactant reagent that is readily biodegradable in the subsurface will be
applied directly to the target monitoring and proposed injection wells (MW-5, MW-9,
INJ-1, and INJ-2). The surfactant will be applied as an aqueous solution not exceeding
6 percent (v/v). A potable water flush will then be applied to the target monitoring and
injection wells.
Injection volumes per well for the proposed events were estimated by multiplying the
vertical height of the well screen or target interval by the radial surface area required to
achieve complete distribution within the treatment area. This value was converted from
cubic feet to gallons and then multiplied by the anticipated porosity of the subsurface
that will accept fluid during the injection (the mobile porosity). Based on ARCADIS'
experience, mobile porosities are less than 10% at sites with similar lithologies to that
observed at former ExxonMobil Facility #42094. Therefore the anticipated injection
volume per wells =10 ft X 3.14 (Tr) x (5 ft x 5 ft) x 10% x 7.481 gal.cg — maximum of
2,400 gallons.
6.0 Injection Procedure and Equipment
The proposed surfactant application locations (MW-5, MW-9, INJA and INJ-2) are
presented as Figure 5. Approximately 2,400 gallons of the surfactant solution will be
delivered in total to the two existing monitoring wells (MW-5 and MW-9) and two
proposed injection wells (INJA and INJ-2). During the surfactant application event,
field crews will mobilize to the site to set up and stage the required above -ground
equipment. Tanks, manifolds, and the pump will be configured to allow injection in all
four wells simultaneously. Flow will be regulated by adjusting the noted valves and
Attachment to the

pumping rates and caution will be taken to ensure that wellhead pressures are kept
below 5 psi. Based on the total estimated volume per well (600 gallons) and the
anticipated injection rate (1.0 gpm), each injection event will take approximately one
day to complete.
The injection schedule will consist of an initial injection event which would occur within
approximately one to two months of approval of the UIC permit. The initial injection
event would occur over approximately one day and would be followed within 48 hours
by a one -day aggressive fluid vapor recovery (AFVR) event. The AFVR event will take
place over one day, and will operate for an estimated eight continuous hours.
However, the duration of the AFVR event will be adjusted to achieve target recovery
volumes. The one day AFVR will be conducted on monitoring and injection wells MW-
5, MW-9, [NJ-1, and INJ-2 to push/pull the surfactant/potable water mixture through the
subsurface to degrade free product and recover dissolved -phase COC concentrations
exceeding the applicable North Carolina GCL standards. Groundwater recovery will be
monitored to ensure recovery of at least two times the injected volumes. Following
each event, recovered petroleum impacted groundwater will be disposed of properly at
the EMES-approved HAZ-MAT Environmental Services (HAZ-MAT) facility located at
210 Dalton Avenue, Charlotte, Mecklenburg County, North Carolina.
Following the Biosolve® surfactant application and one day 8-hour AFVR event,
ARCADIS will conduct a comprehensive groundwater sampling event of monitoring
wells MW-5 and MW-9. Based on the evaluation of the data gathered during the
groundwater monitoring event, a potential second injection event may be conducted.
Timing of the potential second injection event would take place approximately six
months after the completion of the first injection event.
7.0 Monitoring Plan
Following the completion of the surfactant application and the one -day AFVR event,
ARCADIS will gauge all monitoring wells associated with the site (MW-5, MW-6, MW-7,
MW-8, MW-9, and DW-1) and sample monitoring wells MW-5, MW-7, and MW-9 to
determine the effectiveness of the in -situ surfactant application and one -day AFVR
event. All groundwater samples collected from monitoring wells MW-5 , MW-7, and
MW-9 will be placed in laboratory -supplied containers and shipped to TestAmerica,
Inc. in Nashville, Tennessee for laboratory analysis. In accordance with Table 5 -
Approved Methods for Groundwater Analyses at Petroleum UST Release

for Underground Storage Tank (UST) Releases, July 15, 2008 edition, groundwater

samples will be submitted for analysis of Volatile Organic Compounds (VOCs) by
Standard Method (SM) 6200B.
If warranted based on evaluation of the monitoring data, an additional injection event
may be conducted approximately six months after completion of the first injection
event. The second injection and subsequent monitoring events would be conducted in
a similar manner to the first injection. Pending evaluation of data from the second
injection event, a third injection may be necessary.

BioSolve° Technical Bulletin
BIOS VE The Product and How It Works
HYDROCARBON MITIGATION TECHNOLOGY
BioSolve is a proprietary, water -based blend of non-ionic and anionic surfactants, and other
ingredients specifically formulated to provide unique benefits for the mitigation of
hydrocarbons. When applied as a 3% - 6% solution, BioSolve works on a wide range of crude
oil and hydrocarbon products to:
• Reduce volatility, rendering spills non-flammable, reducing risk from hazardous vapors;
• Enable extraction of contaminants from soil, sand and water; and,
• Increase bioavailability, making hydrocarbons more readily biodegradable.
Surfactants
Surfactants (a contraction of "surface active
agents") are compounds that lower the surface
tension of liquids, allowing easier spreading or
"wetting," and lower interfacial tension
between two liquids (such as oil and water) or
between a liquid and a solid. These functional
characteristics are attributable to the structure
of the surfactant molecule, which includes a
hydrophilic "head" and a hydrophobic "tail."
This means that a surfactant has both a water
insoluble component (or oil soluble component)
and a water soluble component.
Ap• ...Hydrophilic head
Aqueous
solution
• Hydrophobic tail
Surfactant molecules forming a micelle —
encapsulating an oil droplet
Surfactant molecules will migrate to the water surface, where the insoluble hydrophobic group
may extend out of the bulk water phase, either into the air or, if water is mixed with oil, into the
oil phase, while the water soluble head remains in the water phase. This alignment and
aggregation of surfactant molecules at the surface acts to alter the surface properties of
water at the water/air, water/oil or water/solid interface.
Under the right conditions, surfactant molecules will create micelles - spherical structures that
can completely encapsulate an oil droplet so that it will be emulsified in an aqueous solution.
The BioSolve formula has been optimized to achieve this encapsulation and emulsification for
crude oil and hydrocarbons.
BioSolve in Practice
When applied to oils spills, BioSolve encapsulates hydrocarbons, reducing vapor pressure and,
when properly agitated, will make the spill non-flammable. The same principle makes BioSolve
an excellent treatment for controlling fugitive vapors at active remediation sites, for temporary
storage piles of contaminated material and for reducing LEL readings in enclosed spaces,
such as storage tanks.
For in -situ and ex -situ remediation projects, BioSolve reduces interfacial tensions, mobilizing
hydrocarbons trapped in the soil matrix and encapsulating them in an aqueous solution. This
allows for efficient removal and treatment of hydrocarbons with less water than other
remediation protocols. For aquifer remediation, BioSolve strips and desorbs NAPLs from the
matrix and solubilizes them in a tension reduced spherical micellular emulsion.

Waste collected from
remediation projects can be
treated in many activated
sludge ponds or POTWs, subject
to local regulations. Tests have
shown that BioSolve will not harm
aerobic or anaerobic bacteria in
activated sludge operations.
BioSolve also supports
biodegradation by increasing
bioavailability of hydrocarbons.
This natural process is accelerated when hydrocarbons are microencapsulated - increasing
the surface area available to bacteria. In fact, bacteria produce a surfactant to do much the
same thing; so BioSolve is just helping the natural process along. Where soil nutrients are
depleted, BioSolve has produced excellent results when used in conjunction with
commercially available bacteria cultures and nutrients commonly used in bioremediation.
The final products of biodegradation are mostly carbon dioxide, water and cell mass.
BioSolve has been tested under laboratory and field conditions for over 30 years, providing
consulting engineers, regulators and contractors with a high level of confidence in its
performance.

Please find the email chain that started the beginning of this year. It looks like this is one of the expired permits too
and needs to be closed out if there are no future injections planned.
Please let me know within 30 days what the intent of the permittee is as we will start closing out the expired permits
soon.

Yes if you want to rescind the permit. We will have to look at the latest groundwater sampling results to verify that no
impact of injection is seen. Per 15A NCAC 02L.0202, injectants must attenuate to pre -injection concentration levels
or groundwater standards whichever is greater in order for the permit to be closed out. Otherwise a corrective action is
required.

Shristi,
The September 2012 injection event was the only one conducted. The results weren't sufficient to continue.
The wells are being used as monitoring wells so they haven't been abandoned.
I'll find copies of the reports and send them to you. I thought we were sending hard copies of the reports to the UIC
group but I'll verify.
Do we need to submit a formal request to rescind the permit?
Thanks.

Dear Mr. Goodrich:
Are, / rfk
/IRa-AP5
On behalf of ExxonMobil Environmental Services (EMES), ARCADIS G&M of North
Carolina (ARCADIS), is submitting this Response to an Additional Information
Request from the North Carolina Department of Environment and Natural Resources
(NCDENR) requesting additional information for an injection permit at the above
referenced site for your review. Inquiries from correspondence dated March 13, 2012
are included as Attachment 1 and their respective responses are listed below.
1. "Sections B (3) and B (4) of the UIC-5115T Application Form require the
submission of a hydrogeologic description that includes the hydraulic conductivity,
transmissivity, and specific yield of the aquifer to be used for injection, including a
description of the test(s) used to determine these parameters, and the depth to the
mean seasonal high water table. Please submit this information for each of the four
sites. "
Soils at the site consist primarily of silt and clay based on soil boring logs for the site
monitoring wells and soil borings. Saprolitic soil was encountered in all the borings at
depths greater than 10 feet. Imported fill soils consisting of semi -plastic sandy clay
with gravels were observed over much of the site. The fill soil did not extend greater
than 10 feet bgs. Partially weathered bedrock was intersected in monitoring well
borings for MW-7 and DW-1 at depths of 18 feet and 47 feet bgs, respectively.
Competent bedrock was encountered in these two monitoring well borings at 22 feet

and 55 feet bgs, respectively (ERM, Comprehensive Site Assessment Report,
November 2002).
The depth -to -groundwater at the site is approximately 14 to 26 feet bgs at present
(Table 1). However, the historic depth -to -groundwater data indicate that the water
table elevation across the site has decreased by nearly ten feet since 1991.
Groundwater elevation data indicate that ground water flows to the southeast as
shown on Figure 1 (ERM, Comprehensive Site Assessment Report, November
2002).
The hydraulic conductivity of the water table saprolite aquifer was calculated using
slug test data collected from monitoring wells MW-7, MW-8 and MW-9 and the
Bouwer-Rice method (1976). The hydraulic conductivity of MW-7 is 6.59 x 10-4
centimeters per second (cm/sec), MW-8 is 1.54 x 10-3 cm/sec and MW-9 is 9.88 x 10-
4 cm/sec for a geometric mean of 1.00 x 10-3. Hydraulic conductivity in the range of
the calculated geometric mean is typical of a silt aquifer matrix. Slug test data and
calculations are provided in Attachment 2. The groundwater velocity, assuming an
effective porosity of 40%, is calculated to be approximately 0.07 feet/day (25.9
ft/year) (ERM, Comprehensive Site. Assessment Report, November 2002).
Transmissivity is calculated by multiplying the hydraulic conductivity (K) and the
saturated thickness of the aquifer. The hydraulic conductivity value was previously
calculated from monitoring wells MW-7 as 6.59 x 10-4 cm/sec, MW-8 as 1.54 x 10"3
cm/sec and MW-9 as 9.88 x 10-4 cm/sec. The saturated thickness of the aquifer was
calculated by subtracting the assumed soil bedrock interface at 47 feet below ground
surface (ft bgs) from the most recent depth to water in monitoring well MW-7 of 14.75
feet below top of casing (ft btoc). The transmissivity for MW -7 is 60.24 square feet
per day (ft2/day), MW-8 is 140.78 ft2/day and MW-9 is 90.32 ft2/day. The average
transmissivity is 97.11 ft2/day. Calculations are included in Attachment 2. A
potentiometric surface map from the most recent gauging event on March 14, 2012 is
included as Figure 1.
Monitoring well MW-5 was selected for the depth to the seasonal high water table
calculations because it is considered representative of the aquifer. The depth to the
seasonal high water table was calculated by averaging the gauging data in
monitoring well MW-5 from the months of March through May from 2002 to the
present. The depth to the mean seasonal high water table was calculated as 17.70
feet below ground surface (ft bgs). The calculations are presented in Attachment 2.

2. "Sections D (3) and D (4) of the UIC-5115T Application Form require the
submission of a description of the reactions between the injectants and the
contaminants present including specific breakdown products or intermediate
compounds that may be formed by the injections, and summary results of modeling
or testing performed to investigate the injectant's potential or susceptibility to change
(biological, chemical or physical) in the subsurface. Please submit this information for
Retail Facility 42094 (Permit Application W10300192) and Retail Facility. 46477
(Permit Application W10400243)."
BioSolve® is a proprietary formulation of surfactants and other specialty chemicals
developed specifically as a water -based hydrocarbon mitigation agent. BioSolve®
does not have any chemical reaction with the contaminants. BioSolve® will 1)
mobilize contaminants by reducing interfacial tension and 2) solubilize. contaminants,
creating a microemulsion, both with the intention of hydraulically removing
contaminants from the soil.
Under the application scenario proposed, most BioSolve® solution injected into the
subsurface will be recovered and disposed of off -site. At least two times the volume
of injected solution will be recovered. A small volume of Biosolve® may remain in
the subsurface and aquifer groundwater. If so, residual Biosolve® would continue to
be diluted and degraded over time.
Most constituents in BioSolve® are readily degraded in -situ. The most recalcitrant
ingredient in BioSolve® is the nonionic surfactant nonylphenol ethoxylate (NPE).
Biodegradation of NPEs is accomplished by a stepwise shortening of the ethoxylate
chain. This produces a complex mixture of nonylphenol (NP) compounds that can be
divided into three main groups: short -chain nonylphenol ethoxylates, nonylphenol
carboxylic acids and nonylphenol. This initial degradation typically takes place in a
matter of 5 to 10 days as the hydrophilic chain is readily degraded. Subsequent
degradation of NP compounds proceeds relatively rapidly under aerobic conditions
with degradation of approximately 80% of NP in 30 days (Chang, 2006). Under
anaerobic conditions, half-lives for NP range from 23.9 to 69.3 days (Mao, 2012).
3. ' "Section E (3) of the UIC-5115T Application Form requires the submission of a
detailed diagram of the surface and subsurface portions of the system. Please
submit this diagram for each of the four injection systems."
An injection diagram is included as Figure 2.

FORM: WI0300192 staff report ExxonMobile Facility #42094 - Meck June 2012

AQUIFER PROTECTION. REGIONAL STAFF REPORT
Description Of Well(S) and Facilities — New, Renewal, and Modification
1. Type of injection system:
❑ Heating/cooling water return flow (5A7)
❑ Closed -loop heat pump system (5QM/5QW)
® In situ remediation (5I)
❑ Closed -loop groundwater remediation effluent injection (5L/'Non-Discharge")
❑ Other (Specify:_
2. Does system use same well for water source and injection? ❑ Yes ® No
3. Are there any potential pollution sources that may affect injection? ® Yes ❑ No
What is/are the pollution source(s)? A former UST and Dispenser Island. What is the distance of the injection
well(s) from the pollution source(s)? 0 ft.
4. What is the minimum distance of proposed injection wells from the property boundary? —10 ft. and Oft.(former
Dispenser Island is now off -property in Freedom Drive ROW)
5. Quality of drainage at site: ❑ Good ® Adequate ❑ Poor
6. Flooding .potential of site: ® Low ❑ Moderate ❑ High
7. For groundwater remediation systems, is the proposed and/or existing groundwater monitoring program
(number of wells, frequency of monitoring, monitoring parameters, etc.) adequate? ❑ Yes ® No. Attach
map of existing monitoring well network if applicable. If No, explain and recommend any changes to the
groundwater monitoring program: The monitoring plan as proposed only tracks the COC progress in the wells
of interest. The MRO recommends: The installation of a deep well near MW-2R, using both as down -gradient
wells for the INJ2/MW-5 event and the installation of a down gradient monitoring well pair near injection area
INJ-1 /MW-9.
Since the injection is a surfactant, the MRO is okay with the proposed parameter list, but recommends the field
parameters (Conductivity pH, ORP) serve as an indicator... any significant change should reflect a need to
analyze for inorganic parameters (metals sulfates etc). The MRO recommends continued quarterly sampling

8. Does the map presented represent the actual site (property lines, wells, surface drainage)? ® Yes or ❑ No. If
no or no map, please attach a sketch of the site. Show property boundaries, buildings, wells, potential pollution
sources, roads, approximate scale, and north arrow. The add info maps do a better job of depicting GW flow
across the site. But the "Local Area Map" misses the point of the11/4 mile survey. WSWs and SW bodies are
mentioned in the literature, but not shown on the map.

V. EVALUATIONAND RECOMMENDATIONS
1. Provide any additional narrative regarding your review of the application:
This site now houses a vehicle repair facility, but was an ExxonMobile station. Soil and groundwater
contamination were discovered in the early 1990's. NAPL was detected in MW-9 during Oct 2011 sampling. This
application proposes the use of "Biosolve" to treat dissolved phase chemicals of concern (COC) in two localized
areas:
One near the former dispenser Island at MW-9 and Proposed INJ--1;
The second is near the former UST field at MW-5 and proposed INJ-2;
All four of these wells will be used for Injection/Recovery in this proposed Push/Pullprocess. (The MRO will not
issue a separate Recovery Well permit if this permit is approved.) The injection(s) will use a municipal water
source and will consist of a 2400 gal maximum volume per injection event. There will be a maximum of two events
spaced 6 months apart. The surfactant will be introduced as 6% solution via the four wells (600 gals. each in MW-
5, MW-9, INJ-1 and INJ-2). Following the surfactant application (within 48 hrs) a one day aggressive fluid vapor
recovery (AFVR) event will ensue and is proposed to remove twice the injected volume.
The monitoring plan as proposed only tracks the COC progress in the wells of interest. The MRO recommends:
1) The installation of a deep well near MW-2R... using both as down -gradient wells for
the INJ2/MW-5 event.
2) The installation of a down gradient monitoring well pair, near injection area INJ-1/11W--9.
Since the injection is a surfactant, the MRO is okay with the proposed parameter list, but recommends the field
parameters (Conductivity, pH, ORP) serve as an indicator... any significant change should reflect a need to analyze
FORM: W10300192 staff report ExxonMobile Facility #42094 - Meck June 2012 3

AQUIFER PROTECTION_REGIONAL STAFF REPORT
for inorganic parameters (metals, sulfates, etc.). The MRO recommends continued quarterly sampling for a full
year after the last injection event.
This site appears to be free of drilling obstacles, some overhead wires but not directly above areas of concern... will
need to move a few vehicles around in the parking lot. The map reflects a change in the property lines, so the
consultant will require an access agreement to wells within the Freedom Drive ROW Note: All MWs require
maintenance — bolts missine from covers (this was a common occurrence at all ExxonMobile Sites visited
WI0300192. WI0300193 and WI0300194).
The quarter mile survey revealed five inactive water supply wells all NE and up -gradient of the site, with the closest
being 1350 feet from the source area. (The MRO looked at a couple of the residential properties adjacent to the
site... did not see any wells.) Groundwater flow is Southeast across site. The closest surface water feature is
unlikely to be impacted, as it is 500 hundred feet away.
Consultant noted that off -site MW-7 shows Tetrachloroethylene, suspected from former Dry Cleaners on this
property... consultant should follow-up with Inactive Hazardous Sites Branch. Plume delineation is not very clear
from any maps provided, consultant expressed concern -about limited'vertical assessment. The-MRO recommends -.
approval ofpermit, with monitoring/sampling changes as noted. Reminder --to obtain any required MW
construction permits from Mecklenburg County Groundwater and Wastewater Services.

I ant writing in response to a request for a health risk evaluation regarding the use
of 5% BioSolve and 95% water to enhance biodegradation of groundwater contaminated
with petroleum hydrocarbon constituents at the Valero Marketing & Supply Company in
Selma, North Carolina. Based upon my review of the information submitted, I offer the
following health risk evaluation:
WORKER PRECAUTIONS DURING APPLICATION
1. The specific chemicals present in the product BioSolve are not provided for
proprietary reasons at the request of the manufacturer, The Westford Chemical
Corporation. However, some effects reported to be associated with the chemicals
present in the product following short-term exposure are as follows:
Exposure can cause irritation of skin, eyes, nose and throat (Chemical Hazard
Response Information System by Micromedex TOMEs Plus System CD-
ROM Database, Volume 51, 2002; Meditext — Medical Management by
Micromedex TOMEs Plus System CD-ROM Database, Volume 51, 2002).
Significant inhalation exposure can cause central nervous system depression
and lung, liver, and kidney injury (Meditext — Medical Management by
Micromedex TOMEs Plus System CD-ROM Database, Volume 51, 2002).

• Possible interaction with oxidizing materials and acids with generation of heat
(Meditext — Medical Management by Micromedex TOMES Plus System CD-
ROM Database, Volume 51, 2002)
If the -products are released into the environment in a way that could result in a
suspension of fine solid or liquid particles (e.g., grinding, blending, vigorous
shaking or mixing), then it is imperative that proper personal protective
equipment be used. The application process should be reviewed by an industrial
hygienist to ensure that the most appropriate personal protective equipment is
used.
2. Persons working with this product should at least wear goggles or a face shield,
gloves, and protective clothing. Face and body protection should be used for
anticipated splashes or sprays. Again, consult with an industrial hygienist to
ensure proper protection.
3. Eating, drinking., smoking, handling contact lenses, and applying cosmetics
should never be permitted in the application area during or immediately following
application.
4. Safety controls should be in place to ensure that the check valve and the pressure
delivery systems are working properly.
The Material Safety Data Sheets should be followed to prevent adverse reactions
and injuries.
OTHER PRECAUTIONS
1. Access to the area of application should be limited to the workers applying the
product. In order to minimize exposure to unprotected individuals, measures
should be taken to prevent access to the area of application.
2. According to the information submitted by Handex, the area is served by public
water. However, there are five residential properties and one commercial
property located within 400 to 950 feet that use wells for non -potable activities.
According to the information submitted by Handex, the BioSolve product will be
removed during the extraction process, and the likelihood of impact to these
receptors is minimal. Because of the potential risks associated with the use of this
product, efforts should be made to prevent contamination of existing or future
wells that may be located near the application area.

Subject: Monitoring well locations for Permit W10300192
Mr. Goodrich,
Thank you for discussing our permit (W10300192) with me today.
As we discussed, we plan to install one shallow monitoring well and one deep monitoring well approximately 30 feet
downgradient of IW-1 plus one deep monitoring well approximately 30 feet downgradient of IW-2. Note that installing a
deep well in the vicinity of MW-2R (abandoned but adjacent to MW-5) would put the new deep well only about 10 feet
away from IW-2. I have attached a sketch depicting my understanding of the monitoring well installation plan as well as
a potentiometric map for your reference (groundwater generally flowing to the southeast).
The shallow well be installed to bracket the water table and the deep wells would be installed such that the screened
interval is deeper than the new shallow well but does not penetrate bedrock.
Please reply and indicate if my understanding of the monitoring well installation plan is correct.
Thanks again and have a great weekend!

Mr. Frizzell,
Thank you for your email and accompanying diagram regarding the placement of the new monitor wells.
I have taken another look at the site detail map and the recommendations which were made: at the time the permit.was.
issued, and have concluded that the one deep monitoring well and one shallow monitoring well that are going to be
installed in association with IW-1 should be placed 13 feet downgradient (roughly southeast) of IW-1. I have also
concluded that the one deep monitoring well that is going to be installed in association with IW-2 should be placed 13
feet downgradient (roughly southeast) of IW-2. Part of my reasoning for these placements is that they should be just far
enough from their respective injection wells to be slightly beyond on the edge of the injection area, and may or may not
show significant concentrations of injectant.
Thank you for contacting me regarding this issue, and please do not hesitate to contact me if there are any other
concerns.
