V. ATTACHMENTS
As required in Section V. of the Application to use Type 51 Wells for Injection, Additives, Tracers, the following
items are provided in Attachment A: Corrective Action Plan (CAP). Greensboro Travel Center, Incident Number
30318, by Benham Companies LLC, dated May 28, 2010. The CAP was prepared, signed, and sealed by a licensed
geologist by as required by G.S. 89E-13.
SITE HISTORY Page ES-1 and 2 and Pages 1-4 provide a brief description of the site history including:
(1) site usage historically and present.
(2) origin of the contamination,
(3) previous remedial action(s).
HYDROGEOLOGIC DESCRIPTION Pages 1, 9-12, Figures 3-5, Table 4, and Appendix A provide a hydrogeologic
description, soils description, and cross section of the subsurface to a depth that includes the known or
projected depth of contamination including:
(1) the regional geologic setting;
(2) significant changes in lithology;
(3) 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
(4) the depth to the mean seasonal high water table.
INJECTION FLUID COMPOSITION Pages 16-17 and Page 19 describes the methodology of the proposed
placement of powdered magnesium peroxide in fabric socks called oxygen releasing compound (ORC).
Magnesium peroxide is a fine white to off-white powder that releases oxygen by breaking down at a
controlled rate in water. Magnesium peroxide is environmentally benign and widely used in the cosmetic,
QLncultural, pharmaceutical, and environmental industries. Magnesium peroxide is used in the
hioremediation of contaminated so) 11 and to reduce contaminant levels in groundwater. Attachment B contains
Material Safety Data Sheet (MSDS) for magnesium peroxide.
INJECTION RATIONALE Pages 13-17 discuss the rationale for selecting the injectants. Pagesl8-20 and Appendix
B specify the concentrations proposed for injection, including:
(1) goals of the injection project;
(2) explanation and/or calculations of how the proposed injectant volume and concentration were determined;
(3) 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 injection; and
(4) summary results of modeling or testing performed to investigate the injectant's potential or susceptibility to
change (biological, chemical or physical) in the subsurface.
INJECTION PROCEDURE AND EQUIPMENT There is no system construction proposed; therefore, no plans or
lists of materials are necessary. Pages 18-20 provide a detailed description of all planned activities related to the
proposed injection including:
(1) operation procedures; and
(2) injection schedule.

Dear Mr. Schenker:
The Corrective Action Plan (CAP) received on June 3, 2010 has been reviewed by the UST
Section, Winston-Salem Regional Office. The plan and the schedule are hereby approved, with the
following modifications. groundwater samples are to be analyzed by EPA methods 602 and 625 annually
and by MADEP EP11 and VPH methods semiannually, If EPA methods 602 or 625 detect contaminants
above the 2L standards, that analysis method will be required during semiannual sampling.
Failure to implement the plan and schedule in the manner and time specified may result in the
assessment of civil penalties and/or the use of other enforcement mechanisms.
if coverage under the Leaking Petroleum Underground Storage Tank Cleanup Funds (Funds) has
preNrio►esly gr nited or is anticipated, failure to implement the plan and schedule in the manner and
time specified in Vx CAP may result in potential loss of coverage. failure to practice cost effective
implevientatior_ .)f the plan, including soil and groundwater monitoring and operation and maintenance of
any rc—meoini systeri(s) until the date oa which cleanup goals are met, will also jeopardize reimbursement
of reasoual-Ic and :iecessary costs from the Funds.
Effective October 1, 2004, the Department requires that all work following the submittal of the
Limited Site Assessment Report (Title 15A NCAC 2L .0405) be preapproved if State Trust Fund
reimbursement is anticipated. To comply with this requirement, a completed Prcapproval/Claim
Authorization Form, encompassing the required remedial activities, must be received in this office within
14 days of the dale of this letter. Upon completion of the preapproved activities, you should submit your
claim promptly. Reimbursement funds are budgeted based on completed preapprovals, but lengthy delays

(3) 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
(4) the depth to the mean seasonal high water table.
INJECTION FLUID COMPOSITION Pages 16-17 and Page 19 describes the methodology of the proposed
placement of powdered magnesium peroxide in fabric socks called oxygen releasing compound (ORC).
Magnesium peroxide is a fine white to off-white powder that releases oxMgn by breaking down at a
controlled rate in water. Magnesium peroxide is environmentally benign and widely used in the cosmetic,
.tat�uligrA, phinruceutic:tl, and environmental industries. Magnesium peroxide is used in the
bitiremediiation rf contaminated soil and to reduce contaminant levels in Upund" ater. Attachment B contains
Material Safety Data Sheet (MSDS) for magnesium peroxide.
INJECTION RATIONAL Pages 13-17 discuss the rationale for selecting the injectants. Pages 18-20 and Appendix
B specify the concentrations proposed for injection, including:
(1) goals of the injection project;
(2.) explanation and/or calculations of how the proposed injectant volume and concentration were determined;
(3) 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 injection; and
(4) summary results of modeling or testing performed to investigate the injectant's potential or susceptibility to
change (biological, chemical or physical) in the subsurface.
INJECTION PROCEDURE AND E UIPMENT There is no system construction proposed; therefore, no plans or
lists of materials are necessary. Pages 1 S-20 provide a detailed description of all planned activities related to the
proposed injection including:
(1) operation procedures; and
(2) injection schedule.

Corrective Action Plan WP116331TA' rtslGreensboro Incident 3031 S-CAP
Greensboro Travel Center - Incident 30318 - ES 1 - May 2010
EXECUTIVE SUMMARY
On behalf of TravelCenters of America (TA), The Benham Companies, LLC (Benham) prepared
this Corrective Action Plan (CAP) for TA's Greensboro facility located at 1101 North Carolina
Highway bl in Whitsett, Guilford County, North Carolina (the facility). A CAP was required by
a Notice of Regulatory Requirements (NRR) letter from the North Carolina Department of
Environment and Natural Resources (DENR) dated March 1, 2010. This CAP reviews site
history; summarizes subsurface investigation findings; sets objectives for corrective action;
evaluates alternatives for meeting those objectives; and recommends enhancement of the existing
bioremediation process and maintenance of the facility paving to prevent direct human contact
and limit dissolution into groundwater.
The subject of this CAP is the facility diesel fuel dispensing pad, where impacted soil was
discovered during TA's diesel dispenser and piping upgrades in April 2006. TA removed
102.5 tans of hydrocarbon -impacted soil, and DENR assigned Incident No. 30318 for the
release. As no active leakage was present, the source of the release was likely from fuel
dispensing operations. TA followed up with a Limited Site Assessment (LSA) of the diesel
dispenser pad using four sail borings and one monitoring well (DDMW-2). The February 2007
LSA reported no soil impact; however, groundwater was impacted by hydrocarbons at DDMW-
02. The LSA report documented residential supply wells within 1,500 feet, which designated the
facility a high risk classification.
TA further investigated the diesel dispenser pad with a Comprehensive Site Assessment (CSA)
using 19 sail borings and 4 monitoring wells. Of the 40 soil samples collected by the CSA, only
4 locations exceeded the Soil to Groundwater Maximum Soil Contaminant Concentration
(MSCC) limits. The CSA report and addenda, dated .Tune 29, 2009, October 2, 2009, and
January 29, 2010, detected benzene and C9-C22 aromatics above 2L Standards at DDMW-2 and
2-methyl naphthalene and C9-C22 above 2L Standards at CSAMW-3. Benzo(b)fluoranthene was
measured above solubility limits at various wells (CSAMW-1, CSAMW-2, and CSAMW-4)
but was believed to be adsorbed to colloidal particles and not representative of
dissolved concentrations. Liquid -phase hydrocarbon (LPH) was measured in DDMW-2 on

Greensboro Travel Center - Incident 30318 - ES 2 • May 2010
March 31, 2009, amounting to 1.3 fluid ounces, all of which was recovered. No LPH recurred in
April or May 2009, or during purging in September and December 2009. The CSA also
confirmed the active presence of contanunant-degrading bacteria in soil and groundwater. The
impervious surface covering (pavement) at the site prevents direct exposure to the impacted soil
and hydrocarbon dissolution by water infiltration.
Site hydraulic gradient and hydraulic conductivity contribute to very slow (0.025 feet per day)
groundwater migration as expected for the saprolitic soils. Target hydrocarbons attenuate to
below 2L Standards less than 30 feet from the source. The property line is 220 feet from the
source, so there is no risk to water supply wells. Favorable conditions for microbial populations
with capability to degrade hydrocarbons were confirmed. These characteristics combine to make
bioremediation a feasible corrective action, as indicated by the lack of hydrocarbon impact in
downgradient wells MW-15, CSAMW-1, and CSAMW-2. However, the single instance of LPH
suggested a hydrocarbon film on the inner well surfaces of DDMW-2.
This CAP used the data collected by the LSA and CSA to propose corrective action by enhanced
bioremediation. It recommends a single application of dilute (5 percent) hydrogen peroxide in
DDMW-2 to address the residual hydrocarbon film on the inner well surfaces; installation of
Oxygen Releasing Compound (ORC) within DDMW-2 and CSAMW-3 to stimulate the existing
bioremediation; monitoring remedial effectiveness by semiannual groundwater sampling; and
maintaining facility pavement to prevent direct contact with soil and limit dissolution into
groundwater. Cleanup goals for the CAP are DENR's current 2L Standards. Upon attainment of
this goal, the site is eligible for incident closure.

1.0 INTRODUCTION
1.1 Purpose
On behalf of TravelCenters of America (TA), The Benham Companies, LLC ( Benham) submits
this Corrective Action Plan (CAP) for the Greensboro, North Carolina facility. This CAP
responds to the April 2006 discovery of impacted soil at the diesel fuel dispensing pad, which
was assigned Incident No. 30318 by North Carolina Department of the Environment and Natural
Resources (DENR). This CAP summarizes subsurface investigation findings; sets corrective
action objectives; evaluates remedial alternatives; and recommends a remedial option.
1.2 Location and Setting
The facility is situated on a 27.93-acre parcel at 1101 North Carolina Highway 61 in Whitsett,
Guilford County, North Carolina (Figure 1). It is bordered by Greeson Road to the north, Pace
Drive and Interstate 85 to the south, Route 6I to the west, and undeveloped land and an unnamed
tributary to Alamance Creek to the east (Figure 2). The facility features automotive and truck
fueling; a restaurant and motel; convenience store; and truck maintenance shop. The facility is
served by public water and sewer.
The facility lies in the Carolina Slate Belt of the Central Piedmont Physiographic Province of
North Carolina at a surface elevation of approximately 640 feet above mean sea level (AMSL).
Figure 3 provides the site geology, and Figures 4 and 5 illustrate the subsurface profile based on
soil borings around the diesel dispenser pad. The surface is predominated by impervious cover
and landscaped areas, and it slopes south toward Alamance Creek approximately 4,600 feet
distant. The diesel dispenser pad is located at a topographic high on the property.

2.4 SITE HISTORY AND CHARACTERIZATION
2.1 Site Development
The site was undeveloped until the 1987 construction of a truck fueling facility by Pace Oil
Company. It was purchased by BP ail Company and then sold to TA in 1993 (Table 1). The
1987 underground storage tank (UST) system currently remains in service-
2.2 Storage Tanks
2.2.1 Underground Storage Tanks (USTs)
Table 2 and Figure 2 provide the relevant storage tank information. Located on the southwestern
corner of the facility, the UST field consists of eight single -walled 10,000-gallon
fiberglass -coated steel USTs. Five USTs contain diesel fuel, and three contain unleaded
gasoline. The diesel UST system is associated with the diesel fuel dispenser pad in the
northwestern portion of the facility. The gasoline USTs serve the automobile fueling area in the
south-central portion of the facility. The USTs are protected with impressed current and overfill
protection. UST leak detection is by an automatic tank gauging (ATG) system. All pressurized
product pipelines from the USTs to the dispensers are double -walled, fiberglass -reinforced
plastic (FRP).
2.2.2 Aboveground Storage Tanks (ASTs)
The facility has two aboveground storage tanks {ASTs} located southeast of the service station
and restaurant (Figure 2). These are for new motor oil and used motor oil. The ASTs were
installed in 1987 and are inside a concrete basin capable of holding 4,800 gallons of fluid. These
tanks are not associated with any releases at the facility.

2.2.3 Oil[Water Separators
A below -grade oil/water separator (OWS) is adjacent to the ASTs (Figure 2). Surface water
runoff from the diesel fuel dispensing pad flows through the OWS.
2.2.4 Former Tanks
The Comprehensive Site Assessment (CSA) report for Incident No. 6113 (June 1999) states that
the facility formerly contained one 550-gallon fuel oil, one 550-gallon used fuel oil, and one
3,000-gallon diesel fuel USTs, which were removed in 1990.
2.3 Release History and Site Characterization
There were four historic releases and incident numbers at the facility. BP is responsible for a
1990 gasoline release near the gasoline dispensers (Incident No. 6113) (Figure 2). Eagle
Transport Corporation (Eagle) was responsible for a diesel release at the UST field in 2007. TA
is responsible for a 1999 diesel release at the USTs (Incident No. 20054).
TA is also responsible for the April 2006 hydrocarbon -impacted soil discovered during a diesel
dispenser and piping upgrade at the diesel dispenser pad (Incident No. 30318), which is the
subject of this CAP. No active leakage was present which indicated the source was dispensing
spills. The quantity of diesel fuel released is unknown. TA removed 102.5 tons of impacted soil
from the shallow subsurface and conducted a Limited Site Assessment (LSA) of the diesel
dispenser pad with four soil borings and one monitoring well (DDMW-2). The February 2007
LSA report documents residential water wells within 1,500 feet (Table 3), which designated the
facility a high risk classification, although these wells are outside of the groundwater pathway
from the facility. The LSA did not detect any soil impact; however, groundwater had
hydrocarbon impact at DDMW-02.
In 2009, TA further investigated the diesel dispenser pad with a CSA of 19 soil borings and
4 monitoring wells. Of the 40 soil samples collected by the CSA, only 4 were above the

Soils were characterized as a clay -rich residuum of weathered bedrock (saprolite) extending from
approximately 1 foot below grade (fbg) to bedrock at 7 to 20 fbg. The bedrock is
metamorphosed quartz diorite. Depth to groundwater was measured from 0 to 19.05 fbg.
Groundwater hydrologic gradient is toward the south (Figures 7 and 8). Groundwater samples
detected benzene, 2-methylnaphthalene, and C9-C22 aromatics above 2L Standards (Figure 9),
while benzo(b)fluoranthene was not believed representative of dissolved concentrations.
Hydraulic gradient and hydraulic conductivity contributed to a very slow (0.025 feet per day)
groundwater velocity.
2.4 Receptor Information
2.4.1 Water Supply Wells
Public water is supplied to the facility and surrounding residential and commercial properties by
the City of Gibsonville. Telephone discussions with the City of Gibsonville, review of previous
reports for the facility, and a reconnaissance of the surrounding areas determined that 8 private
water wells exist within 1,500 feet of the release (Table 3). However, these wells are located
outside of the groundwater pathway from the facility and at an elevation equivalent to or higher
than the facility (Figure 1).
2.4.2 Public Water Supplies
No public water supply wells or reservoirs are located within 2,500 feet of the release.
2.4.3 Surface Water
The nearest surface water body to the facility is an intermittent tributary to Alamance Creek on
the southwest property margin. This stream flows southeast through a culvert under North
Carolina Highway 61 (Figure 1) and emerges on the south side of Pace Drive, where it enters

another culvert under 1-85. South of 1-85, it combines with another unnamed stream and flows
into Alamance Creek/Lake Macintosh about 4,600 feet south.
2.4.4 Wellhead Protection Areas
No wellhead protection areas are known to exist within the area of this release.
2.4.5 Subsurface Structures
A survey of utilities located along Route 61 and Pace Drive and at the facility was conducted.
Underground utilities, storm drains, and electrical conduits were located by visual inspection,
site maps, and the One Call System. These were screened with a photoionization detector (PID)
capable of detecting organic vapors. The buildings at the facility were not screened as they do
not have basements. No elevated PID measurements were present during the screening, and no
evidence of impact was present in surface or storm water structures.
2.4.6 Land Use and Property Owner and Occupants
The facility is zoned and used as a commercial property. It is surrounded by residential,
agricultural, and commercial/industrial zoned properties. The adjacent property to the east is
undeveloped and is zoned as commercial. North, south, and west of the facility are residential
properties. A list of property owners adjacent to the facility is included as Table 4.

2.6 Initial Abatement and Corrective Actions
2.6.1 Sail Excavation
Initial abatement began upon the discovery of the release during the diesel dispenser
replacements in 2006. Approximately 102.5 tons of diesel fuel -impacted soil was removed from
the diesel dispenser pad. The excavation and post -excavation soil sampling are described in the
June 22, 2006, Soil Sampling Services Report and February 11, 2007, LSA.
2.6.2 Liquid -Phase Hydrocarbon (LPH) Gauging and Recovery
No liquid -phase hydrocarbon (LPH) was reported in soil during dispenser replacements. The
February It, 2007, LSA reported no LPH observed on groundwater (monitoring well DDMW-2)
or in soil borings of October 2006. Other than a single instance of LPH measured in and
recovered from DDMW-2 in March 2009 (Table 5), no LPH was present. No LPH recurred in
DDMW-2 during gauging in April and May 2009 or purging in September and December 2009.

3.0 SUMMARY OF SITE ASSESSMENT INFORMATION
3.1 Dispenser Upgrade Soil Sampling
In April -May 2006, TA replaced the diesel dispensers at the site as described in the
June 22, 2006, Soil Sampling Services Report. Soil samples were collected from 24 locations,
and 102.5 tons of impacted soil were removed from the diesel dispenser pad. Soil sampling
conducted after hydrocarbon -impacted soil removal indicated soil concentrations above MSCC
limits.
3.2 Limited Site Assessment
In October 2006, TA installed four soil borings (DB-01, D13-02, ❑B-03, and D13-04) and one
monitoring well (DDMW-2) for the LSA. The borings penetrated silty clay and clayey silt to
bedrock (6 to 15 fbg), and the soil samples did not detect evidence of impact. A groundwater
sample of DDMW-2 contained volatile organic compounds (VOCs) and extractable petroleum
hydrocarbons (EPH) above the 2L and Gross Contamination Levels (GCL) Standards (Table 6).
The LSA reported that private supply wells were present within 1,500 feet of the site. As a
result, a CSA investigation was required by the DENR to delineate the extent of soil and
groundwater impact.
3.3 Comprehensive Site Assessment
3.3.1 Soil Borings
In March 2009, TA conducted a CSA by installing 19 soil borings and 4 monitoring wells
surrounding the diesel fueling dispenser pad. A total of 40 soil samples were collected using
direct -push methods. No LPH or groundwater was observed in the borings, and refusal (bedrock)
varied from 6.5 to 12 fbg. Sail samples were collected and analyzed for benzene, toluene,
ethylbenzene, and xylenes (BTEX) and polyaromatic hydrocarbons (PAHs). Five soil samples
were analyzed for volatile petroleum hydrocarbons/extractable petroleum hydrocarbons

(VPHJEPH) according to the Massachusetts Department of Environmental Protection (MADEP)
method. Three soil samples were analyzed for grain size, permeability, bulk density, and
fractional organic carbon. Additionally, three soil samples were collected and analyzed for total
heterotrophs, contaminant -degrading organisms, nitrates, and phosphates.
Of the 40 soil samples collected by the CSA, only 4 were above the Soil -to -Groundwater
MSCCs, as summarized on Figure 6. The geotechnical analyses of the saprolite reported hydraulic
conductivity ranging from 6.277E-05 feet per day (ftlday) (2.39E-08 centimeters per second [cmis])
to 3.37E-03 ftlday (1.19E-06 cm/s). The fine texture and low hydraulic conductivity of the saprolite
inhibits hydrocarbon infiltration. Bacteria colonies with enzymatic capabilities to degrade
hydrocarbons were measured. The relatively neutral sail pH and number of colonies indicated a
healthy and diverse contaminant -degrading bacteria population is present in soil.
3.3.2 Monitoring Wells
Four monitoring wells were installed around the diesel dispenser islands (CSAMW-1,
CSAMW-2, CSAMW-3, and CSAMW-4) for the CSA. Weathered bedrock was encountered
between 6.5 and 12 fbg, with no indication of groundwater above bedrock. Groundwater was
encountered in bedrock at 15 to 20 fbg at CSAMW-3 and CSAMW-1, respectively,
Equilibration of groundwater levels took approximately one week. No groundwater was
encountered at CSAMW-2 and CSA.MWA so these wells were drilled to approximately 75 fbg
where the boreholes remained dry. Equilibration of groundwater levels in these wells took
approximately one month. Groundwater levels were monitored monthly from March to
May 2009 and again in September and December 2009. Groundwater gradient slopes south
(Figures 7 and 8) generally following the surface topography.
Groundwater sampling of the wells surrounding the diesel fuel dispensers (MW-4, CSAMW-1,
CSAMW-2, CSAMW-3, CSAMW-4, and MW-15) was conducted in March, April, September,
and December 2009. DDMW-2 contained LPH in March 2009, which was recovered, but the
well was not sampled. Thereafter, LPH did not accumulate in DDMW-2, even after purging to
sample in September and December 2009. Groundwater samples were analyzed for BTEX,

PAHs, VPHIEPH, total heterotrophs, benzene -degrading organisms, methyl tertiary -butyl ether
(MTBE)-degrading organisms, nitrates, and phosphates. The CSA and addenda, dated
June 29, 2009, October 2, 2009, and January 29, 2010, reported benzene and C9-C22 aromatics
above 2L Standards at DDMW-2 and 2-methyl naphthalene and C9-C22 above 2L Standards at
CSAMW-3. Benzo(b)fluoranthene was measured above solubility limits at various wells
(CSAMW-1, CSAMW-2, and CSAMW-4) but was believed to be adsorbed to colloidal particles
and not representative of dissolved concentrations.
Slug testing of DDMW-2, CSAMW-1, CSAMW-2, CSAMW-3, CSAMW4, and MW-15
measured a low mean hydraulic conductivity of 0.03I fit/day (0.232 gallons per day per square
foot [gpd/ft2]). This results in a low groundwater velocity of 0.025 ft/day, or 3.3 ft/year.
Petroleum hydrocarbons migrate at an even slower rate in groundwater, which indicates little
migration from the diesel dispensers, as confirmed by attainment of 2L Standards at the
downgradient wells MW-15, CSAMW-I, and CSAMW-2. On this basis, there is no potential for
hydrocarbon migration to receptors.
Bacteria with enzymatic capabilities to biodegrade hydrocarbons were measured in groundwater.
The relatively neutral groundwater pH and moderate dissolved oxygen levels are conducive to a
healthy and diverse microbial population in groundwater. Soil and groundwater sampling
indicate bioremediation is occurring. Slow groundwater migration and bacterial viability
indicate a potential for bioremediation of the hydrocarbons and lowering the risk classification.
The default remedial goals for soil and groundwater are the lower of the soil -to -groundwater or
residential MSCCs or the 2L Standards. Upon attainment of this goal, the site is eligible for
incident closure.
3.4 Groundwater Modeling
3.4,1 Fate and Transport Model
Groundwater fate and transport modeling was conducted to assess the potential future extent of
regulated substances in groundwater. Specifically, the modeling was used to predict the extent
The Benham Companies, LLC - an SAIC company
Corrective Action Plan WRI6331TA1 1$s Greensboro Incident 30318-CAP
Greensboro Travel Center - tncideni au318 -14 - May 2010
of regulated substances in groundwater up to 10 years in the future. The modeling was
completed using Quick Domenico (QD), a Microsoft Excel spreadsheet application of An
Analytical Model for Multidimensional Transport of a Decaying Contaminant Species, by
P.A. Domenico (Journal of Hydrology, 91 [ 19871, pp 49-58). This model is a peer -reviewed
three-dimensional solute transport model for predicting concentrations in the groundwater in the
future. It was used to calculate the concentration of target hydrocarbons downgradient of the
source and determine where groundwater will be above the 2L Standards ( Appendix A).
3.4.2 Input Data
The source of groundwater impact is releases of diesel fuel from fueling at the diesel dispenser
pad. The downgradient property boundary is located at a distance of approximately 220 feet to
the southwest of the diesel dispenser pad. Target hydrocarbon substances exceeding
2L Standards in groundwater at the site in 2009 included benzene, benzo(b)fluoranthene,
2-methylnaphthalene, and C9-C22 aromatics detected in groundwater by monitoring
wells CSAMW-3 and DDMW-2. other hydrocarbons were detected above 2L Standards in
2006; however, these were not modeled because they no longer exceed 2L Standards.
To be protective, the model was run at maximum concentrations detected by the CSA with the
assumption of no reduction of source concentration with time. Additionally, the retardation
effects of fractional organic carbon (FDC) were set as insignificant (0.05 percent) relative to the
higher measured FQC concentration (2.56 percent). The model required both site- and
compound -specific input from the investigation or as recommended in the model documentation:
• Ax (longitudinal dispersivity): Recommended by model documentation as 0.1 *distance
from the source to the location of concern (property line): 0.1*220 feet = 22 feet.
• AY (transverse dispersivity): Recommended by model documentation as Ax13 = 22 feet/3 =
7.33 feet.
• Az (vertical dispersivit: Recommended by model documentation as Ax120 = 22 feet120 =
1.1 feet.

* Source Width (maximum width of the area of contaminated soils): This value was set at
40 feet based on the characterization groundwater chemistry data and assuming a source
between DDMW-2 and CSAMW-3.
* Source Thickness (the thickness_ of contaminated soils plus the groundwater smear Zane):
This value was set at 10 feet based on the fluctuation of groundwater.
■ Hydraulic Conductivity: Based on the slug testing, the geometric mean of hydraulic
conductivity value at the site is 0.031 feet/day.
■ Hydraulic Gradient: An average gradient measurement of 0.073 fVft was set using the
historic groundwater elevation measurements.
■ Porosity: Using an estimate of effective porosity for the silt and clay beneath the site, a value
of 10% was set.
* Soil Bulk Density: A value of 1.33 was utilized for the soils.
■ Fractional Organic Carbon: A value of 0.05% was used to be conservative. The measured
value for the site soils was 2.56%.
The following shows the input data utilized for benzene as an example. Other targets were
modeled with their specific input 1 fisted on the model output page:
■ Source Concentration: The maximum benzene concentration detected over the past
sampling events was 0.0015 milligrams per liter (mg1L) and was used in the modeled
source area.
* Receptor Concentration: The 0.001 mg/L benzene 2L Standard was used.
* Lambda (first order decay constant): The published benzene attenuation lambda is
0.000959 days t.
* KQHC (organic carbon partition coefficient): The value listed in the United States
Environmental Protection Agency (EPA) guidance for benzene is 98.

configuration and extent of the contaminant plume. Of the four target hydrocarbons, benzene is
the most mobile and has the lowest 2L Standard. The modeling indicates that benzene will not
migrate more than approximately 20 feet before dropping below the 2L Standard. As the
distance to the downgradient property line is 220 feet, benzene will not migrate off the property
at a detectable concentration in groundwater. This is due primarily to the fact that benzene is
present at a relatively low concentration (1.5 micrograms per liter [pg/L]) and the rate of
groundwater migration is exceedingly slow. Although higher in concentration, the C9-C22
aromatics will not migrate beyond 12 feet distance before dropping in concentration below
2L Standards, which indicates low mobility. Even less mobile, 2-methylnaphthlene attenuates
and drops below 2L Standards in a distance of approximately eight feet. Benzo(b)fluoranthene is
not representative of a dissolved -phase impact but is immobile, migrating less than one foot.
The absence of dissolved hydrocarbons in groundwater samples from the three downgradient
wells (MW-15, CSAMW-1, and CSAMW-2) south of the diesel -dispensing canopy supports the
modeling results. Lack of migration owes mainly to low source concentrations, low hydraulic
conductivities, and low hydrocarbon mobility, which translate to no potential risk to receptors.
A Iack of mobility discourages pump and treat for the CAP but supports in -place treatment of
hydrocarbons using bioremediation.

4.0 EVALUATION OF CORRECTIVE ACTIONS
4.1 Alternatives
The default remedial goals for soil and groundwater are the lower of the soil -to -groundwater or
residential MSCCs, as required in the March 1, 2010, Notice of Regulatory Requirements (NRR)
letter to TA. Upon attainment of this goal, the site is eligible for incident closure. A variety of
corrective action alternatives exists to address the hydrocarbons in the soil and groundwater to
meet these goals. Potentially viable alternatives were evaluated with respect to factors such as
ability to meet remedial goals, expected influence of site -specific characteristics, timeliness, and
cost. The following is a discussion of the potential alternatives that could be applied to mitigate
the hydrocarbons for Incident No. 30318.
4,13 Bioremediation
Bioremediation relies on microorganisms (bacteria) to metabolize and degrade hydrocarbon
contaminants into harmless products, primarily carbon dioxide and water. Once the
contaminants are degraded, the bacteria population will decline. The effectiveness of
bioremediation for attaining the remedial goals is dependent upon site -specific factors of nutrient
availability, size and type of microbial populations, oxygen availability, pH, and temperature of
the substrate.
Recent analyses have shown that hydrocarbon -degrading bacteria are present in both the soil and
groundwater and the pH and nutrient availability are favorable. Depressed dissolved oxygen
concentrations in CSAMW-1, CSAMW-3, and DDMW-2 groundwater, relative to other wells with
little or no dissolved hydrocarbons, show bioremediation is ongoing. Oxygen consumption is due to
the fact that hydrocarbon -degrading bacteria are aerobic. The impervious surface paving prevents
direct human contact with contaminated soil but also precludes infiltration of oxygen -rich meteoric
water.

4.1.2 Soil Vacuum Extraction/Bioventing
Soil vacuum extraction (SVE) physically removes hydrocarbon vapors from soil by creating
airflow through the soil with a vacuum pump piped to a well network. SVE is most applicable to
sites with volatile hydrocarbons, such as gasoline, and porous permeable soil. The subject site
does not meet these criteria.
A modification of SVE for less volatile hydrocarbons is bioventing, which inoves lower rates of
air through the soil. Bioventing provides oxygen to assist aerobic bacteria in hydrocarbon
remediation. Hydrocarbon vapors that are released are treated using granular -activated carbon
(GAQ, and the treated air is subsequently discharged. Bioventing below the groundwater (air
sparging) can be accomplished by pumping air into the subsurface below the groundwater.
Groundwater in the vicinity of the diesel dispensing pad is in bedrock; therefore, relatively
shallow treatment by SVE/bioventing will not influence groundwater without the air sparging
component of bioventing.
4.1.3 Soil Excavation and Removal
Upon discovery of impacted soil at the dispenser pad, 102.5 tons of impacted soil were removed
from the subsurface under the pad. Subsequent soil samples indicated the remaining soil impact
was limited to shallow depths because of low soil permeability. Water infiltration and direct
contact with soil are precluded by paving over the area.
The remedial goals for soil might be attained by additional excavation and soil removal, but
groundwater will not be treated by soil excavation. Excavation/removal would necessitate the
existing product piping be removed, which would put the facility out of service for one month or
more. Pre -excavation or soil stockpile samples may be necessary, depending on the
disposal/treatment facility chosen. Based on the spacing of soil borings and an assumption of a
5- to 10-foot excavation depth where. MSCCs are attained, 600 to 800 cubic yards of soil may be
generated. At approximately 1.8 tons per cubic yard, approximately 1,080 to 1,440 torts may be
produced by excavation. Soil sampling prior to backfilling is recommended to document the
The Benham Companies, LLC - an SAIC company
Corrective Action Plan WPI16331TA} rts\Greensboro Incident 30318-CAP
Greensboro Travel Center - Incident :i0318 15 May 2010
removal of the impacted soil. An equal quantity of soil backfill will replace the impacted soils
removed from the subsurface.
Excavated contaminated soils are removed from the site to a permitted landfill or treatment
facility. Landfilling of impacted soil reduces landfill capacity unless it can be used for daily
cover. Treatment involves thermal desorption, asphalt blending, or bioremediation. Positive
considerations for landfilling and recycling include a relatively short time to complete the
operation and no on -site storage necessity. Disadvantages include additional transportation and
treatment expenses. As with all ex -situ methods, this alternative requires replacement of the
removed soils and backfilling with proper compaction.
4.2 Alternatives Cost Estimate
Benham developed cost estimates for evaluating remediation alternatives by
bioremediationlnatural attenuation, bioventing, and soil excavation and removal. The cost
estimates were based on the following assumptions:
1. Currently, the facility pavement and natural soil properties prevent direct human contact
with hydrocarbons and inhibit water infiltration and migration of impacted groundwater.
Bioremediation preserves that isolation status with no additional cost.
2. Bioventing alone does not treat groundwater; therefore, air sparging below the groundwater
would be necessary. All piping for bioventing and air sparging must be underground.
3. The volume and weight of the impacted soil to be excavated and treated (or disposed) are
cost drivers that can be estimated, but the loss of business due to removal of the product
piping are primary costs that are difficult to estimate.
4. For excavation/removal, the dispenser pad would have to be shut down and piping removed,
Excavation would involve removal/replacement of the product piping and electric utilities
disturbed by soil removal and post -remedial soil samples. Backfill would need to be

purchased and installed. Pavement and concrete will need to be replaced with the capacity
to support weight.
Based on Benham's experience in remediation, and the assumptions stated above, the estimated
costs to address the three soil altematives are:
• Option 1: Bioremediation: $20K - $30K.
• option 2: SVElbioventing: $95K - $125K (not recommended).
• Option 3: UST removal and installation and off -site soil treatment by recycling:
$320K - $370K (not recommended due to additional potential exposure and
costs).
4.3 Discussion of Remedial Options
Based on site factors and the relative decrease in hydrocarbon concentrations since 2006,
bioremediation has been and is presently occurring. In the most recent sampling, groundwater
already meets the 2L and GCL Standards except for C9-C22 aromatics in DDMW-2. The CSA
data indicate hydrocarbon degraders are present and conditions are conducive for bioremediation
to meet the remedial goal. Groundwater data from the CSA demonstrate that no hydrocarbon
impact is migrating from the diesel dispenser pad on the site.
The relatively depressed concentrations of dissolved oxygen will slow the process of
bioremediation. Therefore, to speed the process of bioremediation oxygen releasing compound
(CRC), a magnesium peroxide additive, can be applied in wells. CRC increases dissolved
oxygen concentrations in soil and groundwater promoting aerobic metabolism of the
hydrocarbon residuals. Bioremediation enhanced with CRC is the lowest cost alternative and is
recommended.
The Benham Companies, LLC - an SAIC company
Corrective Action Plan WPIl6331TA11 -tskGreensboro Incident 30318-CAP
Greensboro Travel Center - incident ju318 - 17 - May 2010
Remediation of soil Gould be enhanced by bioventing using this alternate means of adding oxygen.
However, the low volatilization potential and the presence of impacted groundwater in bedrock
suggest that the technique would also require air sparging. Based on the additional costs and
limitations of treatment area by the low permeability soil and bedrock, bioventing is not
recommended at this time.
Soil excavation is unnecessary because current conditions isolate the soil and groundwater from
direct contact and infiltrating water. Soil excavation would expose soil for direct contact and
water infiltration and would result in significant costs beyond those for other alternatives. The
product piping system and other underground utilities would need to be shut down, removed, and
reinstalled, creating the potential for an accidental release. Site data demonstrate no potential for
migration to receptors, so this level of effort and cost is unreasonable. Finally, excavation would
not remediate groundwater because groundwater is in bedrock. As soil removal is not justified
and has a host of significant disadvantages, it is not recommended.

5.0 PROPOSED CORRECTIVE ACTION
5.1 Basis of Recommendation
Compared to the historical groundwater sampling results of 2006, the September and
December 2009 groundwater sample results indicate a significant reduction in hydrocarbon
concentrations. The relatively reduced dissolved oxygen concentration in groundwater further
supports that natural processes are degrading the hydrocarbons. As a result of degradation and
low hydraulic conductivity, groundwater downgradient of the diesel dispenser pad meets the
2L and GCL standards. Groundwater and hydrocarbon migration rates are slow, and
surrounding receptors are hundreds of feet away and topographically higher. As a result, no
hydrocarbon -impacted groundwater has migrated from the dispenser area, and the potential of
impact to receptors is low.
5.2 Methodology
Based on the conditions measured, which support an active community of hydrocarbon
degrading organisms and lack of impact downgradient, enhanced bioremediation will be used to
address the remaining hydrocarbon impact from the 2006 diesel fuel release. This methodology
has been well established and accepted by the state and federal agencies and the regulated
community.
Prior to implementing enhanced bioremediation, a single dose of dilute (5 percent) hydrogen
peroxide in water will be applied to DDMW-2. This amendment will serve to oxidize the
residual hydrocarbon film expected to reside as a coating of the inner well casing and screen
walls and to increase the dissolved oxygen. The dissolved phase in the well and residuals on the
well casing are conservatively estimated at a sum of approximately 4.2 grams (Appendix B).
The hydrogen peroxide required to complete the reaction with hydrocarbons is a ratio of 2.17:1;
therefore, using that ratio, a total of 9.1 grams is required. To be conservative, a safety factor of
three times the required reaction amount or 27.3 grams hydrogen peroxide will allow for
treatment of the filter pack and formation skin just outside the well screen. A liter of retail 5

Greensboro Travel Center - Incident JU318 - 19 - May 2010
percent hydrogen peroxide contains 71.5 grams; therefore, 4.4 liter of 5 percent hydrogen
peroxide will be introduced to DDMW-2 for this purpose.
The current population of hydrocarbon -degrading bacteria will be enhanced by increasing the
dissolved oxygen concentrations in groundwater south of the diesel dispenser pad using ORC
socks placed in DDMW-2 and CSAMW-3. A total of 15 feet of 2-inch ORC socks
(5.5 kilograms) will be installed in the groundwater in each well. The reaction of the magnesium
peroxide in the socks and water in the well will produce approximately one kilogram of oxygen
over approximately one year. The oxygen will diffuse into the groundwater surrounding the well
and be available to enhance the bacterial decomposition of the hydrocarbons. If necessary, based
on continued presence of hydrocarbons above the 2L Standards, the socks will be replaced in
kind at the end of one year.
5.3 Remedial Effectiveness Monitoring
Semiannual groundwater sampling will be conducted at wells CSAMW-1, CSAMW-2,
CSAMW-3, CSAMW-4, and DDMW-2 to document remedial effectiveness. if LPH is present,
it will be removed from the well and a modification in the remedial method may be considered.
No groundwater sample will be acquired from a well with LPH. Monitoring wells will be
purged and sampled in accordance with American Society for Testing and Materials (ASTM)
Method D-4448. During purging, water quality data will be recorded with field instruments
including pH, temperature, oxidation reduction potential (ORP), dissolved oxygen, salinity, and
specific conductance. All purge water will be discharged to the facility OWS.
Groundwater samples will be collected from each well with dedicated disposable bailers, placed
in laboratory -provided glassware, and preserved according to ASTM Method D-3694. Samples
will be submitted for analysis of C9—C22 aromatics by MADEP VPHIEPH. Following the
groundwater sampling and receipt of laboratory reports from each semiannual sampling event, a
brief remedial effectiveness monitoring report will be prepared, which will compare the results
of the groundwater monitoring to the 2L Standards. Upon attainment of the 2L Standards, a no
further action (NFA) approval will be sought.

Greensboro Travel Center - Incident JU318 - 20 - May 2010
5.4 Remedial Schedule
Upon approval of the CAP by the DENR, the remedial schedule will include initial hydrogen
peroxide and ORC introduction in the first month. A semiannual schedule of remedial
evaluation monitoring and reporting will then commence, with sampling six months after ORC
introduction. Laboratory analyses from the semiannual sampling will be done on a normal
turnaround, which is approximately two weeks. Reports of the results of sampling will be
submitted within one month of the receipt of laboratory reports.
5.5 Public Notification
As the CAP proposes corrective action by enhanced bioremediation and does not propose
remediation to an alternate cleanup standard, no public notification is required under 15A NCAC
2L .[14Q9(a).

1990
BP is responsible for the 1990 gasoline release.
In May 1999, diesel fuel seeped into a surface water body. The release was reported to DENR and assigned Release # 20054, but the quantity of diesel fuel released was unknown. An October 1999 investigation conducted by ARCADIS Geraghty & Mil ter
(Arcadis) confirmed soil and groundwater impact, including liquid -phase hydrocarbons (LPH) within 35 feet of the Facility USTs. The investigation recognized the source as broken seals in the UST drop tubes and identified a preferred pathway for discharge of
diesel to a storm sewer near the USTs. That pathway was a 4-inch drain pipe, which was subsequenity closed. As a result of the release 13,212 gallons of liquid -phase hydrocarbon (LPH) were recovered and 300 tons o f contamin ated soils were removed. A
20054
Diesel Fuel
1999
CAP was previously proposed by Sierra Piedmont Engineers and Geologists and approved by DENR in September 2003. It consisted of quarterly Aggressive Fluid and Vapor Recovery (AFVR) for one year with two AFVR events the following year.
Groundwater samples were to be collected one week after each AFVR event. Between March 2003 and November 2004, three AFVR events removed a total of 3,194 gallons of water and 133 gallons of LPH. In November 2004, DENR reclassified the release to
a lower risk and TA suspended remediation, but in September 2007 DENR raised the risk level and required TA to implement the approved September 2003 CAP.
The April 2006 release was manifested as soil impact by diesel fuel under the diesel dispenser pad discovered during a dispenser replacement project. The quantity of diesel fuel released was unknown. The vicinity of the diesel dispenser pad was investigated by
30813
Diesel Fuel
April 2006
a LSA dated February 2007. The LSA did not detect a soil impact at the locations of the soil borings; however, well DDMW-02 con firmed a groundwater impact west of the dispenser pad. The site risk is high due to wells within 1,500 feet of the Site and as a
result a CSA is being prepared.
None
Diesel Fuel
2047
Eagle Transport Corporation was responsible for the 2007 release, which was caused by overfills of the diesel Fuel USTs. Approximately 6.79 tons of soil, one AFVR event on MW-12, a quarterly monitoring and groundwater sampling of MW-12 was conducted.
Assi ed
This release was not assigned an incident number, and was issued a Notice of No Further Action by DENR in September 2008.

INTRODUCTION — Revised 3108*
Quick Domenico.xis (QD) is a Microsoft Excel spreadsheet application of "An Analytical
Model For Multidimensional Transport of a Decaying Contaminant Species", by P.A.
Domenico, Journal of Hydrology, 91 (1987), pp 49-58. QD solves the following
equation with two modifications to be discussed below:
� I erfc [x — 1 +4 v2 gu81+4�Il C(x,y,z,t)=) I2� 11
�J
erf[(y+Y12)124t-ii]—e+---Y12)12�c-4xjj�erf��z+ZI2)2�ax]—e+—ZJ2)12�]}
where:
x = distance from planar source to the location of concern (i.e. property line) along the
center line of the plume.
C(x,y,z,t) = the concentration of the Contaminant at location x, y, z from the source at
time t.
Q, = source concentration - the highest concentration of the contaminant in the
groundwater at the source.
a,,=dispersivity in the x direction.
ay = dispersivity in the y direction .
a,, = dispersivity in the z direction.
erf = error function
erfc = complementary error function
k= hydraulic conductivity.
i = hydraulic gradient
ne = effective porosity (entered as a decimal fraction - (i.e..25)
v = specific discharge. (kiln,)
k =1st order decay constant.
SW = width of source area.
SZ = depth of source area.
x,y,z - these are the spatial coordinates in the horizontal, transverse and vertical
directions that define the point or points where concentration information is desired.
t - this is time since the plume source started moving
In QD this equation has been modified in two ways_
First, "v" has been modified to include a retardation factor
defined as 1+ (KOC*foc*pt,l nj.
where:
KOC = the organic carbon partition coefficient
foc = fraction of organic carbon expressed as a decimal percent
pe= the dry bulk density of the aquifer matrix
and n, = effective porosity.
Secondly, the term "Z12" in the last two error function terms of the equation have been
replaced by "Z" as described by Domenico (1987), page 53, to account for dispersion in
the vertical axis in only the downward direction, as would occur with contaminants at the
water table in a thick uniform aquifer and the source geometry for which this application
is designed.
SYSTEM REQUIREMENTS
IBM Compatible PC
Windows 3.1 or later
Microsoft Excel 5.0 or later - with Analysis Too] Pack running. (On menu bar, click
Tools, AddIns, Analysis ToolPak)
Intel 486 (or comaptible) or later processor recommended.
General Application Information
Overview
Quick Domenico(QD) calculates the concentration of contaminant species at any point
and time downgradient of a source area of known width, thickness and strength. The
kinds of contaminants for which QD is intended are dissolved organic contaminants
whose fate and transport are can be described or influenced by first order decay and
reaction with organic carbon in the soil. The model allows for first order decay,
retardation and three dimensional dispersion, which will be discussed below. In
addition, QD calculates the concentrations in a two dimensional 5x 10 grid whose length
and width are set by the user. The output of the grid is plotted on an Excel chart each
time the any element of the input data is changed. This allows users to see almost
immediately the effects of changes in input data.
Upon selection and input of the final input parameters, the output can be printed on any
Windows compatible printer using a pre-set print area.
Limitations
QD is based on the Domenico analytical model referenced above. Only a single value of
any one of the 20 or so flow and transport parameters required by the model are allowed
at any one time. Therefore the model should not be used where any of these parameters
vary significantly in direction or magnitude over the model domain. Further, QD uses
physical properties of the soil such as dry bulk density and fraction organic carbon which
are difficult to relate to or determine for fractured bedrock aquifers. Therefore QD
should be used with caution in these environments. Q❑ is primarily intended for use in
unconsolidated (soil) aquifers with reasonably uniform physical and hydrogeologic
properties.
QD is primarily intended for use with dissolved organic compounds and radioactive
compounds that may react with organic carbon in the soil and/or may be subject to
biodegradation or reaction that can be described by 1 st order decay. The fu^st order
decay constant (lambda) should be set to zero where the biodegradability of the
compound or its decay rate is questionable. (e.g. MTBE). QD is not appropriate for use
with organic compounds that are undergoing transformation to daughter compounds (e.g.
TCE to DCE). QD considers compounds individually and assumes no reaction between
compounds.
Despite these many limitations, the Domenico model has been successfully applied to
actual data from contaminated sites. In addition, QD has application as a "conceptual"
model where hypothetical or "worst case" conditions are investigated. By using
conservative input assumptions, QD may be useful in Pennsylvania's Land Recycling
Program in providing quantitative support to qualitative fate and transport analyses
based solely on professional experience or opinion at sites which do appear to justify the
time, expense and data requirements associated with more rigorous numerical modeling
efforts.
Color Scheme
The cells in the spreadsheet have been color coded to assist in use and understanding.
Light Green - these cells allow the user to enter data.
Light Yellow - these cells are locked and calculated by the spreadsheet.
Other Colors - these cells are used for labels and other information not critical to use of
the application.
Units
Where input requires a certain unit of measurement, it has been indicated. Because the
spreadsheet contains internal formulas that depend on the units of the input data, use of
improper units will result in spurious results.
Cell By Cell Description - Input Data
The following section discusses the information that is input cell by cell. The discussion
will emphasize conservative selection of parameters where appropriate.
132: D2 Enter project name
B3 Enter the date that application was prepared.
A9 Source Concentration in mgll - QD allows one source concentration which is
applied to the entire width and thickness dimensions of the source. The source is
presumed to be continuous, which makes QD inherently conservative for use at
sites where sources have been removed or remediated. For conservative use,
enter the highest concentration in the groundwater determined from the site
characterization.
B9 Distance to Location of Concern (x) (in feet) - this is the distance measured from
the source, perpendicular to the water table contours, to the point where a
concentration is desired.
C9 Longitudinal Dispersivity - (Ax) - dispersion parallel to the direction of
groundwater flow and water table.
D9 Transverse Dispersivity - (Ay) - dispersion perpendicular to the direction of
groundwater flow and parallel to the water table.
E9 Vertical Dispersivity - (Az) - dispersion perpendicular to the direction of
groundwater flow and water table. In QD, only vertical dispersion downward
below the water table is considered.
These parameters are dispersion terms which describe the extent to which
contaminants spread out from the source into areas that cannot be accounted for
by advective transport alone. Initially these parameters are often estimated and
then adjusted in order to calibrate a model to better fit actual field conditions.
Several relationships have been proposed for initial estimates of Ax, Ay, and Az.
These are:
Ax- Xl10 where X is the distance a contaminant has traveled by advective
transport (i.e. velocity x time)
Ay = Axl1 Q
Az = Ax120 to Axll q00. In general, it is recommended for conservative use of
QD to use a very small vertical dispersion of .001, unless vertical monitoring and
calibration can reliably justify a larger number. Because of the way QD is set up,
a vertical dispersion of zero cannot be used. A value of about .001 is suggested
for initial uncalibrated or conceptual applications.
F9 Lambda (days) - this is the first order decay constant. It is determined by
dividing .693 by the half-life of the compound (in days). The value is determined
from literature or by calibration to existing data. Dispersivity values and lambda
are the two most important calibration terms available in this application. QD is
very sensitive to the lambda term. For conservative use of QD, use the lowest
lambda from the range of values listed in literature references. For compounds
that are not biodegradable or at sites where biodegradation is not occurring use a
lambda of zero. For initial estimates of lambda, see Appendix A, Table 5 of the
Act 2 regulations.
G9 Source Width (R) - enter the maximum width of the area of contaminated soils
that have been impacted, or the maximum width of free product or smear zone of
contamination measured perpendicular to the direction of groundwater flow. Data
should be based on and justified by site characterization data.
H9 Source Thickness - typically this is the thickness of contaminated soils that
contribute contamination to the water table plus the water table fluctuation that
creates a smear zone.
A 14 Hydraulic Conductivity (k)(fllday) - the hydraulic conductivity of a geologic
material is a measure of it's ability to transmit water. The hydraulic conductivity
is determined from pumping or slug tests or, sometimes, laboratory tests using
standard ASTM or other methods described in numerous hydrogeology text
books. QD allows only one hydraulic conductivity measurement to be input. For
conservative use, use the highest conductivity value measured at the site.
B14 Hydraulic Gradient (ft/ft)- this is the slope of the water table in the direction of
ground water flow. QD assumes horizontal flow and a uniform hydraulic gradient
(planar water table). Hydraulic gradient of the water table should be measured at
each site. A minimum of three wells drilled to the same depth into the geologic
formation is required to determine the hydraulic gradient.
C14 Effective Porosity - (decimal fraction- e.g..25) — effective porosity is the
dimensionless ratio of volume of interconnected void spaces in a geologic
material to the total volume of material. Effective Porosity can be determined by
sending soil samples to a laboratory or, if the texture of the material is well
described, by estimating the value from text books or literature references. For
conservative use of QD use a reasonably low effective porosity value from the
range of measured or estimated values.
D 14 Soil Bulk Density -(Pb) (glcm3) - this is the dry weight of a sample divided by its
total volume in an undisturbed state. QD is not particularly sensitive to this
parameter. Samples can be sent to a lab for measurement or a value of 1.8 is
often estimated.
E 14 KOC - this is the organic carbon partition coefficient and is chemical specific.
During formulation of the Act 2 regulations, the Department went to considerable
time and expense, using outside expertise, to develop the most up-to-date KOC
values. These are provided in Appendix A, Table 5, of the Act 2 regulations. Use
these KOC values unless the KOC value is determined for the specific site.
F14 Fraction Organic Carbon (foc) - (decimal fraction) - this is the organic carbon
content of the soil. This value can be determined by a soil laboratory using
ASTM methods. Samples for organic carbon should be taken from the same soil
horizon in which the contaminant occurs, but from an area that has not been
impacted. For conservative use of QD, use the lowest of the range of values
determined or estimated. One/half of one per cent (.005) is a commonly
estimated value.
G14 Retardation - the spreadsheet calculates this value automatically. It is defined as
1 + (KOC* foc *pbtn).
H 14 Velocity (V) - (ftlday) - is the rate of groundwater flow. The spreadsheet
calculates this value automatically from the previous inputs.
A18 This cell is automatically filled by transfer of the `X' coordinate in B7. The value
is repeated here simply to facilitate the view of the x, y and z coordinates for
which the spreadsheet calculates a solution.
1318 `y' (ft) This is the `y' coordinate for which a solution is desired. For a solution on
the centerline of the plume downgradient from the source, y would be set equal to
zero. Otherwise'y' is equal to distance that the location of concern is offset from
the centerline along a line perpendicular to the centerline. Both positive or
negative values may be entered; however, because QD provides a symmetrical
solution, there is no difference in the values obtained.
C 18 `z' (R)This is the `z' coordinate in the vertical axis at x,y of the location of
concern. For most applications this should be left at zero since this value will
yield the highest concentration which is at the water table.
D18 `t' - (days) - this is the time (in days), after a contaminant began moving in the
groundwater, for which a solution is desired. By adjusting the spreadsheet with
the scroll bars so that both the grid, graphic chart and time can be seen at the same
time on the screen, adjusting the time progressively upward provides a graphical
way to determine at what time steady state is reached for the particular set of
input conditions represented by the input data.
C26:C27 These cells are where the user sets the grid dimensions for the 5 by 10 grid
that appears in cells C29::K33. By setting length at 500 ft and width at 50 feet,
for example, the grid would cover a length of 500 feet and a width of 50 feet on
either side of the source origin. Concentrations in the plume are calculated
increments of lengthl10 or 50 feet in this example, and for width/ 2 or 25 feet. By
changing grid sizes, the user will very quickly see how grid dimensions are
affected.
Output Data
A22:B22 These cells contain the source concentration calculated for the specific
location and time defined in A 18 through D 18_
B29:K33 These cells contain the output for the grid defined by the grid dimension
input in A26 and A27. For the grid output, z is fixed at zero by the spreadsheet.
The output from the grid is automatically displayed in a Microsoft Excel chart located
above the grid.

Calculation of Hydrogen Peroxide Oxidation Reaction
for Residual Hydrocarbons in Well ❑DMW-2
Estimate of Residual Petroleum Hydrocarbon in DDMW-2:
❑DMW-2 is 2-inch well with 25 feet of water = 15 L
Dissolved Concentration 4.8 mg/L EPH X 15 L = 0.073 g
Minimum Detectable Free Product* at <0.01' = 4.1 g
Total Hydrocarbons = 4.2 g
Molecular Weight
Petroleum Fuel (C15-H32): 237 glmole
Hydrogen Peroxide (H2-02): 34 glmole
Reaction Balance:
If:
Then:
15 1-12-02 + C15-H32 = 30 H20 + 15 CO2
15 moles H2O2 X 34 glmole = 510 g H2-02; and
1 mole C15-H32 X 235 glmole = 235 g C15-H32
Ratio of 1-12-02 to C15-H32 far complete reaction
Amount of Hydrogen Peroxide for Complete Reaction:
Using the Ratio of 2.17 H2-02 to C15-H32, the
approximate 1-12-02 for complete reaction is:
As a safety factor and to assure treatment of the
DDMW-2 filter pack as well as the well internal
surfaces assume a 3X amount of 1-12-02 at:
Hydrogen Peroxide density =
Hydrogen Peroxide at 5% dilution contains:
2.17:1
9.1 g
27.3 g
1430 g1L
71.5g/L
Therefore: approximately 0.4 Liter 5% Hydrogen Peroxide is needed.

Incident Number 30813
To Whom It May Concern:
On behalf of TravelCenters of America (TA), Benham Companies, LLC submits the attached Application
for Permit to Construct and/or Use a Weil(s) for Injection at the captioned property. The purpose of this
application is to obtain permission from the North Carolina Department of Environment and Natural
Resources (NCDENR) to place Oxygen Releasing Compound (ORC) in two groundwater monitoring
wells to enhance biodegradation of petroleum hydrocarbons in groundwater.
ORC is powdered magnesium peroxide in a porous fabric sock manufactured by Regenesis.
About 15 pounds will be placed in each of two wells to be treated. On immersion in water ORC
gives off oxygen in a slow bubbling action over about one year. The material increases
dissolved oxygen in soil and groundwater and promotes aerobic bacteria metabolism of the
hydrocarbon residuals. Bioremediation enhanced with ORC was recommended in the May 28,
2010 Corrective Action Plan (CAP) for Incident Number 30813. The CAP was prepared for and
approved by the NCDENR Division of Waste Management UST Section on July 12, 2010,
We trust this explanation and UIC application will meet your approval and are prepared to implement it
upon your direction. Please respond to the undersigned with any questions or your approval.

Dear Mr. Schenker.
The Corrective Action Plan (CAA) received on June 3, 2010 has been reviewed by the UST
Section, Winston-Salem Regional Office. The plan and the schedule are hereby approved, with the
following modifications: groundwater samples are to be analyzed by EPA methods 602 and 625 annually
and by MADEP EY11 and VP1l methods semiannually. If EPA methods 602 or 625 detect contaminants
atmve the 2L standards, that analysis method will be required during serniarrnual sampling.
Failure to implement the plan and schedule in the manner and time specified may result in the
assessment of civil penalties anchor the use of other enforcement mechanisms.
If coverage under the Leaking Petroleum Underground Storage Tank Cleanup Funds (,Funds) tsar
been previously granted or is anticipated, failure to implement the plan and schedule in the manner and
time specified in the CAP may result in potential loss of coverage. Failure to practice cost effective
implementation of the plan, including soil and groundwater monitoring and operation and maintenance of
any rear celial system(s) until the dale on which cleanup goals arc met, will aJso jeopardise reimbursement
of reasonable and accessary costs from the Funds.
Effective October 1, 2004, the Department requires that all work following the submittal of the
Limited Site Assessment Report (T?tle 15A NCAC 2L .0405) be preapproved if State Trust Fund
•rimbursement is anticipated. To comply with this requirement, a completed PreapprovsllCiaim
Au[horiration For n, encompassing the required remedial activities, must be received in this office within
14 days of the date of this letter. Upon completion of the preapproved activities, you should submit your
claim promptly. Reimbursement funds are budgeted based on completed preapprovals, but lengthy delays
in reimbursement can occur if claims are not submitted immediately following wont completion.

Incident No. 30318
Injection Permit W10400164
Dear Ms. Lepard:
On behalf of TravelCenters of America (TA), SAIC Energy, Environment, & Infrastructure, LLC
(SAIC) is submitting this Groundwater Monitoring Report to the North Carolina Department of
Environment and Natural Resources (DENR) for Corrective Action Plan (CAP) implementation
and Oxygen Releasing Compound (ORC) installation at the diesel dispenser pad of above -
referenced facility (Figure 1). The July 12, 2010 CAP approved ORC installation in wells
CSAMW-3 and DDMW-2 and required semi-annual sampling of the wells around the facility
diesel dispenser pad (CSAMW-1, CSAMW-2, CSAMW-3, CSAMW-4, and DDMW-2) until the
groundwater meets DENR's 2L Standards. Semi-annual sampling was first conducted in
October 2010. The second sampling was delayed from April 2011 to July 2011, with DENR
permission, to order that an underground injection control (UIC) permit be issued for the ORC
and so the ORC affects could be evaluated. This report covers the period through July 14, 2011.
METHODS AND ❑BSERVATIONS
After receipt of the UIC permit, SAIL installed socks containing approximately 15 pounds ORC
each in wells CSAMW-3 and DDMW-2 on April 14, 2011. SAIL measured water levels (Table
1) and groundwater field parameters, pH, temperature, oxidation reduction potential (ORP),
dissolved oxygen (DO), and specific conductance (Table 2), in the dispenser pad wells prior to
ORC installation. SAIC measured water levels and field parameters again June 11, 2011 and
July 14, 2011.
On July 14, 2011, SAIL gauged the monitoring wells at the site, including those for the diesel
dispenser pad prior to sampling. No liquid -phase hydrocarbon (LPH) was measured or observed
on the groundwater in any monitoring well. The hydrologic gradient was south, consistent with
that reported previously (Figure 2).

Ms- Mindy Lepard - 2 - October 5, 2011
Five monitoring wells (CSAMW-1, CSAMW-2, CSAMW-3, CSAMW-4, and DDMW-2) were
purged and sampled in accordance with ASTM Method D-4448. Groundwater samples were
collected, placed in laboratory -provided glassware, and preserved according to ASTM Method
D-3694. They were submitted to Accutest Laboratory for analysis of Massachusetts Department
of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH) and extractable
petroleum hydrocarbons (EPH) in accordance with EPA publication SW-846. Analytical results
are compared to historical results and 2L Standards on Table 3. Copies of laboratory reports are
included as Attachment A.
FINDINGS
The July 14, 2011 groundwater sample results at the diesel dispenser pad indicated a significant
reduction in hydrocarbon concentrations compared to the historical groundwater sampling
results. The groundwater at monitoring wells was non -detect for C9-C18 Aliphatics (adjusted)
and C9-C22 Aromatics (adjusted) at all wells except DDMW-2. Groundwater from DDMW-2
was less than the 2L Standards for C9-C 18 Aliphatics (adjusted), but exceeded the 2L Standards
for C9-C22 Aromatics (adjusted).
The introduction of ORC into DDMW-2 and CSAMW-3 boosted their DO concentrations by 2.1
milligrams per liter (mglL) and 8.5 mglL, respectively, over previous DO measurements. This
higher DO was available to support biodegradation of the hydrocarbons. Groundwater migration
rates are slow, and the downgradient wells indicate compliance with 2L Standards. These
conditions and the fact that surrounding receptors are hundreds of feet away and topographically
higher than the site indicates no potential of impact to these wells from the site.
Based on the conditions measured, which document a decreasing impact at groundwater at the
diesel dispenser pad, lead SAIL and TA to recommend continued semi-annual monitoring for
Incident No. 30318. The next scheduled semi-annual sampling will be in October, 2011,
Please contact the undersigned at (717) 901-8843 should you have any questions or concerns.
