EXECUTIVE SUMMARY
The following Corrective Action Plan (CAP) has been prepared by Froehling & Robertson, Inc.
(F&R) for the former Uzzle Cadillac-Oldsmobile-GMC Truck facility located at 3737 Chapel Hill
Boulevard in Durham, North Carolina. The location of the facility is shown on Drawing 1.
This CAP has been prepared to address the release of petroleum hydrocarbon compounds that were
released from two underground storage tank (UST) systems located on the site. The subject USTs
formerly stored diesel fuel/gasoline, and virgin oil. The following is a summary of the CAP:
SOURCE INFORMATION
Type of Contaminant: Gasoline, diesel fuel and motor oil.
Source of Release: Motor oil was released from a 550 gallon UST. Diesel fuel and gasoline were
released from a 2,000 gallon UST, and associated product lines and dispenser.
Amount of Release: Unknown
INITIAL ABATEMENT/EMERGENCY RESPONSE INFORMATION
No phase separated hydrocarbons have been detected on the site, therefore, no abatement measures
were performed.
SAMPLING/INVESTIGATION RESULTS
Nature and Extent of Impacted Soil and Groundwater
Two releases are present on the site:
• Gasoline/Diesel Fuel UST (UST-2): Soil adsorbed petroleum hydrocarbons are present near
the former diesel fuel/gasoline UST location with concentrations above Soil to Groundwater
MSCC regulatory standards. Groundwater impacted from a release of gasoline and/or diesel
fuel is present in the vicinity or the former UST system. The compounds benzene, toluene,
xylenes (total) and C9-C 10 aromatics are present in concentrations that exceed the North
Carolina surface water standards multiplied by 10 (1 OX2B surface water standards).
• Virgin ail UST (UST4): Aromatic compounds with the carbon range of CI I-C22 were
found in the soil with concentrations exceeding Residential MSCC. Groundwater has been
detected downgradient of the former UST with levels of C I 1-C22 aromatics that were above
1 OX2B surface water standards.

In addition, the following area was found to be impacted:
■ Offsite Location (MW-17): Groundwater impacted with motor oil is present at this location.
The source of the motor oil was not identified during the assessment and does not appear to
' be associated with the subject USTs.
Maximum Contaminant Concentrations -Groundwater
1 Groundwater remediation will be conducted to lower the levels of dissolved hydrocarbons drocarbons to a
p Y
' level that does not exceed ten times the North Carolina surface water standards (15A NCAC 213
.0200, Classifications and Water Quality Standards Applicable to the Surface Waters of North
Carolina). The following table shows the maximum concentrations of dissolved phase compounds
that were detected in concentrations exceeding lOX2B surface water standards in groundwater

Applicable Soil Cleanup Levels Soil Cleanup
The site is ranked Intermediate Priority, therefore, current cleanup levels are Soil to Groundwater
MSCC. The proposed soil cleanup levels are the Residential MSCC. The Residential MSCC will be
applicable once groundwater is remediated to IOX213 surface water standards.
NoPOsm GROUNDWATER REMEDIATION
Mobile Multi -phase Multiphase Extraction Extraction
It appears active groundwater remediation will be necessary to bring levels of dissolved phase
petroleum hydrocarbon compounds to within 10X213 surface water standards. Groundwater
remediation will be performed using existing monitoring wells MW-8, MW-9 and MW-10 that are
located inside the plume boundaries. Mobile multi -phase extraction (MMPE) is recommended for
site groundwater remediation.
Estimated Cost
It is estimated each MMPE event will cost $9,000.00. This cost does not include periodic
groundwater sampling and monitoring. Groundwater sampling and monitoring costs are estimated at
$3,000.00 per event.

Schedule
MMPE may be performed once per quarter until the LPH is removed and the dissolved phase
hydrocarbon concentrations are lowered to IOX2B surface water standards.
PROPOSED SOIL REMEDIATION
Sail Excavation. and_Offsite Treatment/Disposal
Soil remediation will be conducted a the former location of UST-4. Based on the soil remediation
alternatives, soil excavation and off -site treatment appears to be a viable remediation method. Soil
will be removed to the water table depth of approximately 1.5-2 feet BGS. Approximately 3 cubic
yards (5 tons) of soil will require excavation to meet the C11-C22 Residential MS CC goal of469
mg/Kg. Soil removal will be additionally performed to remove LPH, if present. Fluids contained in
the excavation will be removed at the time of the soil removal activities.
The soil will be excavated and transported off -site for treatment at a NCDENR permitted treatment
facility. The excavation will be backfiiled with either clean fill soil or gravel. The concrete paving
will be replaced at the excavation area.
Estimated Cost
Based on a soil removal volume of 5 tons and NC Trust Fund reimbursable rates (March 1, 2003) for
excavationlbackfiliing ($29.001ton) and treatment/disposal ($30.001ton), the estimated cost for soil
remediation is $300.00. The cost does not include soil removal monitoring and closure sampling.
1 Schedule
1 Soil excavation activities will be conducted prior to or following the completion of the groundwater
cleanup goals.

1.0 SITE INFORMATION
1.1 PROPERTY DESCRIPTION
The site is an operating retail sales and repair facility for General Motors vehicles. The facility is
located on 3737 Chapel Hill Boulevard (US 15-501) in Durham, North Carolina as shown on
Drawing 1. The property is currently leased to the General Motors Corporation and is operated as the
University Cadillac-Buick-Pontiac-GMC Oldsmobile, however, Uzzle Cadillac-Oldsmobile-GMC
Truck retains ownership of the property.
The property contains 4.75 acres and is almost entirely paved with asphalt and concrete. The facility
was constructed in 1969 and has been in continual use for the sale and maintenance of automobiles
since that time. The facility is serviced by below -ground utilities that include phone, municipal
water, sanitary sewer service, storm sewers, gas and electricity. Site utilities are shown on Drawing
2.
Two buildings are located on the property. The main building consists of an automotive dealership
building that contains a showroom, sales offices, service reception area, personnel offices, parts
department, paint and body shop, service bays, a wash down bay and an automatic car wash. A
smaller building used for storage is located at the southeast property corner. The buildings along with
additional site features are shown on Drawing 2.
The site has undergone assessment for releases of hydraulic fluid that originated from below -ground
hydraulic lifts. The assessment included the collection of soil samples, monitoring well installation
and the collection of groundwater samples. Monitoring wells installed for the assessment include
MW-4, MW-6, MW-11, MW-12, MW-13 and MW-14. The assessment activity is documented in a
report prepared by F&R titled Revised Comprehensive Site Assessment and Corrective Action Plan.
The report was submitted to the North Carolina Department of Environment & Natural Resources,
Division of Water Quality (DWQ) on April 11, 2001. Remediation of impacted soils by natural
attenuation was approved by the DWQ for the site.

1.2 FACILITY USTS AND RELEASE SOURCES
The site formerly contained four UST systems identified as UST-1 through UST-4. The former UST
locations are shown on Drawing 2. The following is a brief description of each UST.
1.2.1 UST-1 (GASOLINE)
UST-1 had a capacity of 10,000 gallons and stored gasoline. UST-1 was removed in 1992 and is not
associated with this CAP. Monitoring well MW-1 was installed for the evaluation of groundwater
quality at the UST-1 location following the removal of the UST. The closure of UST-1 was
documented in a report that was prepared by EMS Environmental, Inc. (EMS) and submitted to the
North Carolina Department of Environment, Health and Natural Resources, Division of
Environmental Management (DEM). With the exception of groundwater sampling for lead, no
further assessment activity has been conducted at this location.
1.2.2 UST-2 (GASOLINE -DIESEL FUEL)
UST-2 had a 2,000 gallon capacity and was installed in 1969 for the storage of gasoline. The UST
was also used for the storage of diesel fuel and was serviced by a dispenser that was located adjacent
to the west wall of the automatic car wash. The UST was removed in June 1991. A release was
discovered associated with UST-2 during the conductance of a Phase E Limited Site Assessment in
1998. The release was further assessed during a Comprehensive Site Assessment (CSA) conducted
in 2001 and 2002.
1.2.3 UST-3 (Waste Oil)
UST-3 contained waste oil and had a 550 gallon capacity. The UST was removed in June 1991. A
release has not been detected at the UST-3 location.
1.2.4 UST-4 (VIRGIN OIL)
UST-4 contained virgin oil and had a 550 gallon capacity and was removed in June 1991. A release
is associated with the UST.
1.3 GROUNDWATER CLEANUP LEVELS
The site is ranked Intermediate Priority due to the presence of a buried culvert located along the
north property boundary. The buried culvert channels surface water and appears to be located in a

former stream channel. The applicable DWM groundwater cleanup levels for Intermediate Priority
sites are the North Carolina surface water standards (NCAC, 2B, .0208, Classifications and Water
Quality Standards Applicable to Surface Waters of North Carolina) multiplied by a factor of 10. in
this CAP the standards will be referred to as the 10X2B surface water standards. The version of the
surface water standards used for this report was updated by the NDCDENR on November 14, 2002.
1.4 SOIL CLEANUP LEVELS
The site is ranked Intermediate Priority, therefore, the applicable cleanup levels are Soil to
Groundwater Maximum Soil Contaminant Concentrations (MSCC). However, the proposed soil
cleanup levels are the Residential MSCC. The Residential MSCC would be applicable once
groundwater is cleaned up to'10X2B surface water standards.
1.5 MAXIMUM LEVELS OF IMPACTED GROUNDWATER
Groundwater remediation will be conducted to lower the levels of dissolved phase hydrocarbons to
1OX213 surface water standards. The following table shows the maximum concentrations of
dissolved phase compounds that were detected in concentrations exceeding 1OX213 surface water
standards. The concentrations were detected in groundwater samples collected in March 2003.

Additional soil and groundwater assessment activity was conducted in March and May 2003.
Monitoring wells were sampled in March 2003 during a "baseline" sampling event. A description of
the groundwater sampling activity is discussed in Appendix A.
The soil quality at the locations of UST-2 and UST-4 were additionally assessed in May 2003 during
a -soil boring assessment. A description of the soil boring activity is discussed in Appendix B. Soil
boring logs from the assessment are attached in Appendix C.
The following is a brief description of the extent of soil and groundwater impact identified at each
UST location.
1.8.1 UST-2
A plume of dissolved phase hydrocarbons is present at the former location of UST-2. The plume
appears to have originated from the UST and associated dispenser island and/or product line. The
plume contains benzene, toluene, xylenes (total), and C9-C 10 aromatics with concentrations that
exceed 1 OX2B surface water standards. The plume originating from UST-2 is detected in shallow
monitoring wells MW-5, MW-8, MW-9, MW-10 and MW-11. The extent of the dissolved phase
compounds benzene, toluene, xylenes (total), and C9-C 10 aromatics as present during the March
2003 sampling event are shown on Drawings 3-6, respectively. Volatile compound analytical results
are summarized in Table 1. Semi -volatile analytical results are summarized in Table 2. MADEP
VPH and EPH results are summarized in Table 3. Chromium and lead results are summarized in
Table 4, and geochemical data is summarized in Table 5. Copies of the March 2003 laboratory
analytical report forms are included in Appendix D.
Analytical data collected from monitoring wells installed near the core of the plume have not shown
a significant decrease of concentrations of petroleum hydrocarbon concentrations from the initiation
of groundwater sampling in July 1998 to the last sampling event conducted in March 2003. Graphs
of historical analytical data in selected monitoring wells are included in Appendix E. However, as
shown on Table 5, geochemical indicators suggest that natural attenuation is occurring. These
indicators include elevated levels of iron in impacted wells MW-9 and MW-11, and decreased levels
of dissolved oxygen in MW-8, MW-9 and MW-11. Based on the historical sampling data, it does not
appear natural attenuation alone will be effective for site groundwater remediation.

The direction of groundwater flow in the vicinity of UST-2 is oriented north to northwest towards a
buried culvert pipe that is located along the north property boundary. The depth to groundwater
varies from the upgradient portion of the plume to the downgradient portion of the plume.
Groundwater depths from the ground surface have varied from approximately 3-5 feet upgradient at
MW-10 to 8-10 feet in downgradient monitoring well MW-9. Drawing 7 displays the groundwater
surface and flow direction during the March 2003 groundwater sampling event and was prepared
from data listed on Table 6.
Soil adsorbed petroleum hydrocarbons are present near the former UST-2 system location. The
compounds benzene, ethylbenzene and xylenes (total) are present in concentrations that are greater
than Soil to Groundwater MSCC but do not exceed Residential MSCC. The distribution ofbenzene,
ethylbenzene and xylenes (total) are shown on Drawing 8. The compounds appear to be present from
approximately 0.5 feet below ground surface (BGS) to the water table depth which has occurred
from 3-5 feet BGS in MW-10. Soil volatile analytical data is summarized on Table 7. MADEP VPH
and EPH analytical data is summarized on Table 8. Analytical report forms are included in Appendix

assessment activity has been performed at this location. However, groundwater sampling has been
performed in the associated source monitoring well MW-3 for sidegradient delineation of impacted
groundwater that originated from UST-2 and UST-4.
1.8.3 UST4
Aromatic hydrocarbons with the carbon range of C I 1-C22 have been detected in MW-2 and MW-4

2.3 SURFACE WATER
Surface water enters the site in an incised drainage channel located at the northeast property corner.
This channel is identified in the Southwest Durham USGS topographical map (Drawing 1) as an
intermittent stream. Upgradient storm water is channeled into a storm water culvert pipe that runs
along the north property boundary under a grassy median located adjacent to the Rt. 15-501 service
road. All drainage water from the Uzzle facility enters the culvert through storm grates. This culvert
is approximately 7 feet in diameter, and it appears it was installed in the bed of an intermittent
stream. The presence of groundwater drainage into the pipe has not been established at this time and
would require groundwater elevation monitoring in adjacent wells for comparison to the bottom
elevation of the culvert pipe. The culvert location is shown on Drawings 2-7
The culvert pipe runs to the southwest when it leaves the Uzzle property and continues underneath
the adjacent Southern States Volkswagen property, and former South Square Mall. Upon leaving the
former South Square Mall property, the drainage feature is identified on the topographical map as a
perennial stream. This stream discharges to Sandy Creek, which empties into New Hope Creek. New
Hope Creek empties into Jordan Lake approximately 2-1/4 miles southwest of the Uzzle facility.
According to the 1973 Southwest Durham USGS map, one remaining surface water feature is
located near the site. A pond is located across and approximately 600 feet north and upgradient of the

2.4 WELLHEAD PROTECTION AREAS
1 According to the NCDENR [I ], no wellhead protection areas are located near the site.
' 2.5 SUBSURFACE STRUCTURES
Buried utilities may cause a preferred migration pathway for groundwater or petroleum hydrocarbons
' if they are installed within the water table. Factors including permeable material that may surround
the conduit and leaky joints (in the case of storm water or sewer lines) may also cause migration of
' petroleum hydrocarbons. Subsurface utilities are located at the site, along Auto Drive and the Rt. 15-
5,01 service road. Approximate locations of the utilities are shown on Drawing 2. The utilities
' include the following:
■ Storm sewers
1
• Sanitary sewer
+ Water line
'
• Electric line
1
Natural gas line
The presence of these buried utilities indicates that the potential exists for migration of petroleum
hydrocarbons through these conduits. In order to assess migration of contaminants around or through
the conduits, the exact location and burial depth of the conduits would need to be identified. The
approximate location of the conduits have been identified, however, the burial depths are not known ,
at this time.
2.6 LAND USE AND PROPERTY OWNERS -OCCUPANTS
The property located adjacent to the site is used for commercial purposes. The west property
boundary is bordered by Auto Drive and the Southern States Volkswagen car dealership. The north
property boundary is bordered by Rt. 15-501. Commercial properties are located across Rt. 15-501
from the site. The east property boundary is bordered by the Durham Ritz car wash. The south
property boundary is bordered by the former Darnons restaurant. The adjacent properties are listed on
Table 9.

3.0 PROPOSED CORRECTIVE ACTION
3.1 GROUNDWATER REMEDIATION OBJECTIVES
The following are the objective of groundwater remediation:
•- Reduce the levels of dissolved phase hydrocarbons below l OX213 surface water standards.
• Soils impacted with hydraulic fluid are present at the west and east service bays. Groundwater
remediation should he performed to minimize the mobilization of the hydraulic fluid compounds.
■ Remove liquid phase hydrocarbons (LPH), if present.
The remediation goals will be 10X2B surface water standards.
3.2 EVALUATION OF GROUNDWATER REMEDIATION ALTERNATIVES
Groundwater remediation should address the presence of dissolved phase hydrocarbons and LPH.
Treatment methods evaluated include different versions of pump and treat, air sparing with soil
vapor extraction, and multi -phase extraction. All of these treatment methods are reimbursable by the
North Carolina Leaking Underground Storage Tank Trust Fund.
3.2.1 PUMP AND TREAT & CLOSED LOOP PUMP AND TREAT
System Process
Standard pump and treat technology involves the removal of groundwater from recovery wells using
electric or pneumatic pumping systems. The removal of groundwater creates a cone of depression
that changes the local groundwater gradient and draws groundwater toward the recovery wells.
Liquids removed by pumping may be treated by air stripping and/or carbon filtration.
The treated water at the site may only be discharged to an infiltration gallery or storm sewer.
Discharge to a sanitary sewer is not allowed by the City of Durham. Discharge to an infiltration
gallery would require the construction of an infiltration gallery at a location upgradient of the plume.
Water discharged to the gallery would migrate downgradient and help dilute the plume and
potentially cut down the treatment time.
This method is costly and is primarily used if LPH and/or elevated levels of dissolved phase
petroleum hydrocarbons are present in the groundwater.

,eel
• The site does not offer obvious impediments for system installation.
• Would likely contain migration of dissolved phase hydrocarbons.
• Would likely lower petroleum hydrocarbon concentrations to 1 OX213 surface water standards.
1 Limitations
1
• Does not treat impacted soil.
• Requires periodic scheduled maintenance.
Discharge to a storm sewer would require a National Pollution Discharge Elimination System
(NPDES) general permit.
• On -site discharge to an infiltration gallery would require a DWQ non -discharge permit.
■ May require extended treatment time.
3.2.2 PUMP AND TREAT & SOIL VAPOR EXTRACTION
System Process
This method is the same as pump and treat, however, soil vapor extraction (SVE) is additionally
used to increase groundwater recovery and the cleanup of the vadose zone. This method requires the
installation of SVE lines, a blower and an effluent line. Effluent vapor would be discharged to the
atmosphere and would likely not require treatment.
Feasibility
• As feasible as stand alone pump and treat.
1 Limitations
u
• Same limitations as pump and treat, however, vadose zone soils are remediated.
3.2.3 AIR SPARGING AND SOIL. VAPOR EXTRACTION
' System Process
Air sparging is the introduction of air into the groundwater table to remediate the saturated and
' unsaturated zones. Air sparging is performed by injecting air into the groundwater to strip the
dissolved phase compounds and to introduce oxygen into the subsurface to facilitate biodegradation.
' The vapors created by sparging are captured with soil vapor extraction. Air sparging is viable if the

soils are permeable and heterogeneous, and the contaminant of concern is volatile.
Feasibi l itylLimitations
Does not appear to be feasible at the site due to the presence of low permeability soils and
partially weathered rock.
3.2.4 MULTI -PHASE EXTRACTION
System Process
Multi -phase extraction (MPE) uses a liquid ring pump to simultaneously remove groundwater, LPH
and soil vapors. As opposed to pump and treat, MPE uses a single high vacuum pump instead of
multiple recovery well extraction pumps. MPE is much more efficient than pump and treatlSVE as it
uses a high vacuum (20-29 inches of mercury) to extract the groundwater, LPH and soil vapor. MPE
is an effective method for soils with a limited permeability. The extracted groundwater and soil
vapors are treated and discharged using the same methods as pump and treat-SVE.
I
Feasibili
• The site does not offer obvious impediments for system installation.
• Treats impacted soil as well as groundwater.
• The remediation period is usually quicker than pump and treatlSVE.
I
Limitations
• Installation costs are usually higher than pump and treat due to the cost of the liquid ring pumps.
3.2.5 MOBILE MULTI -PHASE EXTRACTION (MMPE)
System Process
This method is the same as MPE, however, the MPE process is performed for a short duration using
a mobile treatment unit. The liquid ring pumps are connected to monitoring wells or recovery wells
using above -ground hose or below -ground conduit. The groundwater and LPH is pumped from the
wells and discharged to a tanker truck or trailer. The vapor generated from the recovery wells is
discharged to the atmosphere. MMPE events are often performed for five continuous days and are
spaced at intervals from three to six months apart.
Uzzle Cadillac-Oldsmobile-GMC Truck, Inc 13 July 15, 2003

FAR
IBBS
Feasibility
• Does not require the installation of a permanent treatment system.
1 . Does not require a permit for the discharge of groundwater or LPH. Effluent is treated and
discharged at a permitted facility.
' • Events can be performed as needed until 10X2B surface water standards are obtained.
Limitations
' • May require multiple events.
3.2.6 NATURAL ATTENUATION
' System Process
' Natural attenuation or remediation would involve degradation of the petroleum hydrocarbon
compounds by several processes. These processes include degradation by naturally occurring
' organisms, dispersion and advection, dilution, and sorption. The rate of natural attenuation is
measured by groundwater monitoring. Measurements of certain naturally -occurring dissolved
constituents (oxygen, carbon dioxide, nitrate, and phosphate) along with measurements of dissolved
phase compound concentrations may be used to determine the rate of degradation occurring from the
' aforementioned processes. This process is approved by the NCDWQ as a viable remediation
approach (North Carolina Administrative Code Title 15A Section .Q 106(L)).
Natural remediation is most effective when two conditions are met: 1) the constituent of concern has
' the ability to degrade in the environment; and 2) groundwater travel is slow enough and the
contaminant concentrations are low enough so the processes of natural attenuation have time to
' develop and work.
Feasibility LILimitations
' • Analytical data collected from monitoring wells installed near the core of the plume have not
shown a significant decrease of concentrations of petroleum hydrocarbon concentrations from
the initiation of groundwater sampling in July 1998 to the last sampling event conducted in
March 2003. Based on the sampling data, it does not appear natural attenuation alone will be
effective for site groundwater remediation.

remediation methods that may be used at the site. MMPE will be used at the site as it appears to be
an effective remediation technique and will likely provide a cost savings over standard multi -phase
extraction or pump and treat-SVE. MMPE will incur a cost savings over permanent treatment system
installation due to the following:
■ Recovery line trenches will not be installed. Recovery trenches would provide a considerable
cost as the site is paved with concrete that is 4-6 inches thick.
• Treatment system installation costs are eliminated.
• A discharge permit (Non -discharge permit or NPDES permit) would not have to be obtained.
Normal system operation -maintenance costs are eliminated.
3.3.1 MOBILE MULTI -PHASE EXTRACTION SYSTEM DESCRIPTION
MMPE will be performed on the site utilizing a subcontract MMPE firm. The firm will be selected
prior to each event, therefore, specific equipment designs are not included in this CAP. However,
typical MMPE systems consist of the following:
• A pump capable of producing a vacuum of between 20-29 inches of mercury.
■ A vapor -water separator.
• Vapor exhaust stack. The vapor emissions will be treated prior to discharge, if required. Vapor
may be treated by an electric -catalytic oxidizer.
■ Total flow meter, vapor flow meter and pressure gauges.
• Electric generator.
The MMPE system will also require the following components:
■ "Stinger" pipes for insertion into the recovery wells for fluid -vapor recovery.
• Caps for sealing the wells to prevent vapor breakthrough at each wellhead
• Effluent hose.
• Tanker truck or trailer for fluid storage. The tanker will be fitted with a high level switch to
cutoff the MMPE system when the tank is full.
MMPE be performed in existing 2-inch inner diameter monitoring wells MW-8, MW-9 and MW-10.
MMPE will not be conducted in MW-11 to minimize the mobilization of hydraulic fluid compounds
that are present at the west service area. The monitoring wells are located within the gasoline -diesel
plume as shown on Drawings 3-6.
Groundwater is available in each well for MMPE. Monitoring well MW-8 is constructed to 13.4 feet
BGS and contains 3.5-4.5 feet of groundwater, MW-9 is constructed to 13 feet BGS and contains 4-5
feet of groundwater, and MW-la is constructed to 12 feet BGS and contains 6.5-7.5 feet of water.

The referenced water column thickness in each well represent water level measurements collected in
April 2002 and March 2003.
Once extracted, fluid from the recovery wells will be discharged to an on -site tanker truck or trailer.
The fluids will be disposed at a NCDENR permitted facility.
3.3.2 MMPE MONITORING AND GROUNDWATER SAMPLING PARAMETERS
Remediation parameters will be collected from the MMPE system during each event for
measurement of the effective radius of influence, fluid and vapor flow rates, and vapor effluent
concentrations. The following measurements will be collected from the MMPE system:
• System vacuum in inches of mercury.
• Influent fluid and vapor flow in cubic feet per minute (CFM)
• Effluent vapor flow in CFM.
■ Discharge concentrations of volatile hydrocarbons using a photoionization detector (PID) or total
vapor analyzer (TVA).
• One vapor bag sample will be collected per event for analysis of volatile aromatic hydrocarbons
using EPA methods 601-602.
Measurements will additionally be collected from selected monitoring wells to evaluate groundwater
drawdown and vacuum influence. Monitoring wells MW-11, MW-12, and MW-14 through MW-18
will be measured for the following parameters:
• Drawdown using an oil/water interface probe or electric water level probe. Drawdown
measurements will be collected before, during, and after each event.
• Vacuum using magnehelic gauges.
Groundwater monitoring consisting of groundwater sampling and water -fluid level gauging will be
performed in selected monitoring wells following each MMPE event. Groundwater samples will be
collected for analysis of compounds that have exhibited Ievels of petroleum hydrocarbons above the
14X2B surface water standards. The following samples will be collected for laboratory analysis from
the listed monitoring wells:
• EPA method 602 expanded to include xylenes, MADEP VPH, MADEP EPH: MW-8 through
MW-12, MW-14, MW-15, MW-16, and MW-18.
• MADEP EPH: MW-2 and MW-4.

3.3.3 MMPE AND GROUNDWATER SAMPLING -REPORTING SCHEDULE
MMPE will be performed quarterly until the levels of dissolved phase hydrocarbons decrease to
levels that do not exceed lOX213 surface water standards. Once the levels of dissolved phase
hydrocarbons fall below the 10X213 surface water standards, MMPE will be terminated, however,
groundwater sampling will continue. Groundwater sampling will be performed following each event
to evaluate the effectiveness of MMPE. It is anticipated that the MMPE events may be performed
for up to two years. The actual number of events that will need to be performed is not known at this
time and may only be estimated following the first event. Groundwater sampling will be conducted
until the 1 OX213 standards have not been exceeded for one year. At that time a recommendation for
for site re -ranking to Low Priority (and closure) will be requested from the DWM.

A groundwater remediation and sampling report will be issued to the DWM at the schedule noted in
the above table. The report will be prepared in accordance with the Guidelines for Assessment and
Corrective Action, North Carolina Storage Tank Section, duly 1, 2002 or another DWM document
that is current at the time of report preparation.
3.3.4 ESTIMATED MMPE COSTS
Each MMPE event will cost approximately $9,000.00. Table 10 provides a breakdown of estimated
MMPE costs.
3.4 SOIL REMEDIATION OBJECTIVES
The site is ranked Intermediate Priority, therefore, the current soil cleanup levels are the Soil to
Groundwater MSCC, It is anticipated the site rank will be lowered to Low Priority once the
groundwater is remediated to levels that do not exceed the 1OX2B surface water standards. Once
the site is ranked Low Priority, Residential MSCC regulatory levels will apply. The soil cleanup
level goals will be the Residential MSCC in expectation of attainment of the groundwater cleanup
goals. An additional remediation goal will be the removal of LPH that maybe present in the vicinity
of MW-2.
3.5 EVALUATION OF SOIL REMEWATION ALTERNATIVES
Impacted soils with compound concentrations above Residential MSCC levels were only detected at
the UST-4 location, therefore, the UST-4 location will only require remediation. Due to the sorptive
ability of the virgin motor oil, the site soils may be remediated by excavation or natural attenuation.
Soil vapor extraction was not considered a viable remediation technique due to the lack of short
chain volatile compounds within motor oil. These methods are summarized below.
3.5.1 SOIL EXCAVATION
System Process
Soil excavation is effective in removing soil adsorbed petroleum hydrocarbons from the unsaturated
zone. This method is most effective when the groundwater table is shallow and no buildings or
structures are present above the impacted soils. This method would require the removal of soils that

' contain petroleum hydrocarbons above the Residential MSCC levels. Soil would be excavated and
transported offsite for treatment at a NCDENR permitted facility. Treatment would consist of
landfarming, thermal treatment or bioremediation.
Feasibility
t Appears to be feasible as the impacted soils at the UST-4 location only extend to approximately
PP p Y pp Y
2 feet BGS.
• Would not require long term monitoring.
• Would not require permitting.
Limitations
' ■ Would not be effective in removing impacted soils if they extend beneath the building
foundation.
' 3.5.2 NATURAL ATTENUATION
System Process
' Natural attenuation is the process of allowing the concentrations of petroleum hydrocarbon
compounds to decrease by bacterial degradation. The breakdown products are carbon dioxide and
' water.
IFeasibili
■ Costs would be low compared to the excavation and disposal of impacted soil.
' Limitations
■ It will likely take an extended period of time for the aromatic cleanup levels to reach applicable
Residential MSCC.
• The degradation rate would be difficult to measure.
' 3.6 PROPOSED SOIL REMEDIATION

viable remediation method for the site as it appears natural attenuation will take an extended period
of time.

3.6.1 SOIL REMEDIATION DESCRIPTION
Soil excavation will be performed at the UST-4 location. Soil will be removed to the water table
depth of approximately 2 feet BGS. Groundwater and LPH that maybe present in the excavation will
also be removed at that time. Approximately 3 cubic yards (5 tons) of soil will require excavation to
meet the C 11-C22 Residential MSCC goal of 469 mg/Kg. This tonnage is based on a horizontal area
of 40 square feet by 2 feet deep at 1.5 tons per yard. The proposed area of remediation is shown on
Drawing 9.
The soil will be excavated and transported off -site for treatment at a NCDENR permitted treatment
facility. The excavation will be backfilled with either clean fill soil or gravel. The concrete paving
will be replaced at the excavation area.
3.6.2 SCHEDULE OF SOIL, EXCAVATION
Soil excavation activities will be conducted prior to or following the completion of the groundwater
' cleanup goals.
3.6.3 CLOSURE SAMPLING
IJ
Soil samples will be collected from each sidewall for analysis of MADEP EPH compounds. The
excavation will be terminated in the groundwater table, therefore, no bottom excavation closure
samples will be collected. The number of samples collected will be determined by the length of each
sidewall in accordance with DWM guidelines.
3.6.4 ESTIMATED SOIL EXCAVATION COSTS
Based on a soil removal volume of 5 tons and NC Trust Fund reimbursable rates (March 1, 2003) for
excavation/backfilling ($29.001ton) and treatment/disposal ($30.001ton), the estimated cost for soil
remediation is $300.00. The cost does not include soil removal monitoring and closure sampling.

GROUNDWATER ASSESSMENT FIELD METHODS
Site monitoring wells were sampled on March 27 and 28, 2003.On March 26, 2003, the monitoring
wells were gauged for depth to water using a Keck oil -water interface probe. All shallow monitoring
wells were purged of a minimum of three well volumes with disposable latex gloves and single use
disposable polyethylene bailers. Deep well MW-7D was purged with a submersible pump.
The groundwater was then poured into laboratory supplied bottles and preserved with the appropriate
acid (if required). The bottles were chilled to approximately 4°C in iced coolers and remained in
possession of F&R until overnight shipment to F&R's North Carolina certified laboratory. Following
sample collection, field parameters including dissolved oxygen (DO), conductivity, temperature and
pH were measured.
Groundwater samples were collected for the following analysis in the selected monitoring wells:

SOIL ASSESSMENT FIELD METHODS
Soil borings were installed using direct push (Geoprobe") technology by American Environmental
Drilling at locations near the former location of the gasoline -diesel fuel UST system (UST-2), and
former virgin oil UST (UST-2). Soil samples were collected from the borings and field scanned for
Volatile organic compounds (VOCs) with a photoionization detector (PI)} as a semi -quantitative
indicator of the presence of petroleum hydrocarbons. Field scanning was performed by placing the
soil sample in a new resealable plastic bag and allowing the organic vapors to equilibrate in the
headspace for a minimum of fifteen minutes. The PID probe was then inserted into the bag and the
highest VOC reading was obtained.
Soil borings GP-1 A through GP-5A were installed near the former location of UST-2. The sample in
each boring that exhibited the highest VOC concentration and collected from the zone overlying the
water table was submitted to an analytical laboratory for the following analysis:
• Volatile aromatic compounds using EPA method 8260 with an EPA method 5035 extraction.
• Volatile petroleum hydrocarbons using an analytical method developed by the Massachusetts
Department of Environmental Protection (MADEP-VPH).
• Extractable petroleum hydrocarbons using an analytical method developed by the Massachusetts
Department of Environmental Protection (MADEP-EPH).
Soil borings GP-6A, GP-7A and GP-8A were installed at the former location of the virgin oil UST
(UST4). One soil sample was collected from each boring for the following laboratory analysis:
• Extractable petroleum hydrocarbons using an analytical method developed by the Massachusetts
Department of Environmental Protection (MADEP-EPH).
The volatile samples were collected with an En Core sample device fitted with single use En Core
sampler. MADEP EPH samples were collected without headspace in nine -ounce glass jars provided
by the analytical laboratory. The samples remained in possession of F&R until overnight shipment to
F&R's North Carolina certified laboratory.
