SECTIONONE INTRODUCTION
On behalf of Atlantic Richfield Company (ARCO), a BP Products North America, Inc. (BP)
affiliated company, URS Corporation — North Carolina (URS) presents this Corrective Action
Plan (CAP) Addendum for the facility located at 7401 Old Mount Holly Road in Charlotte,
North Carolina (formerly "Southeast Terminals"). The Site has been assigned Groundwater
Incident Nos. 06771, 15159, 15618, 17002, 17263, 17264, and 20622 by the North Carolina
Department of Environment and Natural Resources (NCDENR) in response to various historical
petroleum product release incidents at the facility. The Site priority ranking is currently 100B
due to the presence of potable water -supply wells within a 1,500 foot radius of the Site.
In a letter dated October 14, 2008, NCDENR issued a Notice of Regulatory Requirement
(NORR) requiring BP to provide remediation system modification recommendations in the first
2009 semi-annual groundwater monitoring and remediation report for the Site. A follow-up
letter, sent by NCDENR on April 29, 2009 indicated the requirement to submit a revised CAP to
"implement corrective action in the central plume area." A copy of the letter is included as
Appendix A. This CAP Addendum is intended to address both the October 2008 and April 2009
NORR letters. BP proposed the performance of a pilot study in 2010 and 2011 to collect critical
design parameters necessary to complete the remedy selection and properly design the remedy.
1.1 SITE LOCATION AND DESCRIPTION
Maps showing the Site area and layout are provided as Figure 1 and Figure 2. Figure 2 includes
the locations of all Site monitoring wells. Monitoring well construction information is presented
on Table 1. The Site is located in the Paw Creek area of Charlotte, North Carolina, an area
predominantly occupied by petroleum terminal and light industrial facilities. The facility
occupies approximately 26 acres and is bordered by Old Mount Holly Road to the north, a
Kinder -Morgan terminal to the east, vacant property (former National Oil terminal) to the west,
and undeveloped woods to the south. Railroad tracks operated by Piedmont and Northern
Railroad are located directly south of the facility property, beyond which is situated a Duke
Power transmission line right-of-way.
The Site is a petroleum distribution terminal that has been in operation since the 1940s and was
formerly owned jointly by BP and TransMontaigne. Since February 2006 the facility has been
solely owned and operated by BP. The facility contains 19 bulk fuel storage tanks that are
contained within earthen bermed areas and/or excavated areas with earthen cut -banks. The tank
number, current fuel type, and capacity for the bulk fuel storage tanks are listed on Table 2.
In addition to the bulk fuel storage tanks, the facility contains a terminal office building,
miscellaneous storage and warehouse buildings, nine process aboveground storage tanks (ASTs),
three underground storage tanks (USTs), a covered tanker truck loading rack, and associated
process piping. The tanker truck loading rack is located near the northern border of the facility,
with access from Old Mount Holly Road.
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 1-1

SECTIONONE INTRODUCTION
Six of the process ASTs, ranging in size from 180 gallons to 8,000 gallons, contain fuel
additives. Two 10,000-gallon ASTs contain petroleum contact water. One 2,000-gallon AST
contains mixed (slop) products. The USTs consist of one 1,000-gallon wastewater UST (located
at the sump near tank 110), one 2,000-gallon used oil UST (located adjacent to two 10,000-
gallon underground oil/water separators), and one 2,000-gallon vapor recovery unit (VRU)
moisture separator UST. A total of seven USTs have been decommissioned at the terminal. The
Site underwent a modification between September and December 2008 to include ethanol fuel
storage, and an expanded truck loading rack and driveway widening to accommodate the
expansion.
The terminal is supplied with petroleum products from underground pipelines owned by Colonial
Pipeline Co. and Plantation Pipe Line Co. Two 14-inch diameter feed lines from Colonial
Pipeline enter the facility below ground from the northwest corner. One 10-inch and one 12-inch
feed line from Plantation Pipe Line enter the facility from the southwest corner. Two abandoned
14-inch underground pipelines enter the facility's west side near the warehouse from the former
National Oil terminal. These pipelines formerly supplied product to the former National Oil
terminal via the BP terminal product manifold.
Facility utilities are shown in Figure 2. Onsite utilities primarily consist of aboveground process
piping from the bulk storage tanks to the truck loading rack, overhead electrical and telephone
services, underground low -voltage communication cables, stormwater drain lines, and a septic
system located south of the terminal office. The Charlotte -Mecklenburg Utility Department
(CMUD) supplies potable water service to the facility, Duke Power provides overhead electrical
service to the facility, and Bell South provides overhead telephone service.
The area surrounding the loading rack, office, warehouse, and motor truck shop is paved with
concrete or asphalt. Grass areas exist on the north side of the property along Old Mount Holly
Road. Tank berms, access roads to the tank areas, and the area between the tank areas and the
office/loading rack area are graded with gravel.
Stormwater from the bulk fuel storage tank basins is discharged to a ditch in the southern portion
of the site under a facility National Pollutant Discharge Elimination System (NPDES) permit.
Stormwater from the loading rack containment area is collected in a 10,000-gallon AST and
treated/disposed offsite at licensed facilities. Tank bottom water is collected into tanker trucks
and treated/disposed offsite at licensed facilities.
1.2 SITE TOPOGRAPHIC AND GEOLOGIC/HYDROGEOLOGIC SETTING
The facility is situated on the crest and slope of a hill centered on Old Mount Holly Road.
Ground -surface elevations at the facility range from approximately 795 feet relative to mean sea
level (msl) at the northern border of the facility adjacent to Old Mount Holly Road to
approximately 740 feet msl at the southern border of the facility. South of Old Mount Holly

SECTIONONE INTRODUCTION
Road, surface drainage is south toward Paw Creek. North of Old Mount Holly Road, surface
drainage is north toward Long Creek.
The Site is located in the Piedmont physiographic province, which is characterized by
moderately level interstream areas separated by broad valleys. Bedrock in Charlotte, North
Carolina is mapped within the Charlotte Belt lithologic division of the Piedmont, which includes
mafic gneisses, amphibolites, metagabbros, and metavolcanic rocks. According to the Geologic
Map of North Carolina (NCGS, 1985), bedrock beneath the facility consists of metamorphosed
quartz diorite or quartzite. Groundwater in the Piedmont province occurs in the overburden under
unconfined (i.e., water table) conditions, and in the underlying bedrock under both unconfined
and confined conditions.
Groundwater in the overburden occurs within pore spaces of the unconsolidated medium,
including relict bedrock structures (i.e., fractures, foliations, etc.). Due to the typical fine-grained
nature and low permeability of saprolite, the formation is not usually utilized for groundwater
production. Groundwater in the underlying bedrock occurs along zones of secondary porosity,
such as fractures, foliations, solution voids, etc. Most water -supply wells in the Piedmont are
completed in bedrock with surface casings extending through the overburden.
Competent bedrock in the Piedmont province is typically overlain by variable thicknesses of
saprolite and soil, collectively referred to as "overburden." Saprolite consists of rock that has
been subject to chemical weathering, removing up to 60% of the rock mass by solution, but not
affecting volume (Cleaves, 1974). Saprolite commonly retains relict structures from the parent
bedrock. Thicknesses of the overburden in the Piedmont typically range from 10 to 75 feet,
depending on rock composition and topographic setting (LeGrand, 1988).
Geologic cross sections of the Site were created for this CAP Addendum. Cross section locations
are presented on Figure 3. Cross sections are illustrated on Figures 4 and 5. The cross sections
are located in the central/upgradient area of the Site. This area will be the targeted area for
remediation as indicated in the April 29, 2009 NORR letter and as further discussed in
Section 1.8.
Based on Site boring logs, subsurface materials at the Site consist of soil and saprolite
overburden, including silty/clayey sand, sandy clay/silt, and silt/clay, overlying weathered and
competent bedrock. Bedrock, meeting the description of metamorphosed quartz diorite
referenced above, has been encountered in Site borings at depths ranging from approximately 10
to 40 feet below grade.
Based on historical hydraulic conductivity tests completed for various wells at the Site, the
average test result for monitoring wells screened in the overburden was 8.2 feet per day (CRA,
2004). Assuming groundwater viscosity and density of 0.001 kilogram per meter -second and 1
gram per cubic centimeter, the average intrinsic permeability can be calculated as 2.95 x 10"8 cm2
or 2.95 darcy. These values represent semi -pervious conditions and are consistent with typical

SECTIONONE INTRODUCTION
values for fine sand and silt (Bear, 1972). A seepage velocity of 1.09 ft/day has been calculated
using the above reference hydraulic conductivity of 8.2 ft/day, a hydraulic gradient of 0.02 ft/ft
and an effective porosity of 0.15. URS notes the aforementioned K value was calculated using a
linear average which tends to skew the average K to much higher values. This can cause an
overestimation of the seepage velocity. URS has revisited and recalculated the hydraulic
conductivity utilizing a geometric mean to a value of 1.2 ft/day. This results in a predicted
seepage velocity of 0.16 ft/day.
1.3 SITE MONITORING WELL NETWORK
The locations of Site groundwater monitoring and remediation wells are shown in Figure 2. Site
well construction details are listed in Table 1. The depths of Site monitoring and remediation
wells range from 7 to 110 feet below grade. Ten Site monitoring wells are completed in bedrock
and one Site monitoring well is completed in saprolite directly above bedrock. The remaining
Site monitoring wells are completed in the shallow overburden (i.e., water -table monitoring
wells).
1.4 SUMMARY OF LIGHT NON -AQUEOUS PHASE LIQUID (LNAPL) OCCURRENCE
LNAPL has been historically detected in some Site monitoring wells. LNAPL was not
measureable in any Site monitoring well during the December 2011 gauging event and was last
detected in 2005. Inspection and replacement of LNAPL-absorbent socks for select wells (ES-
05SR, ES-25, ES-33, MW-12, MW-51, UW-10, and VE-02) is completed periodically. LNAPL
gauging data, along with groundwater level gauging data, is included in Appendix B.
1.5 SITE RELEASE AND REMEDIATION HISTORY
1.5.1 Historical Site Release Incidents
Historical releases at the Site have included tank overfills, pipeline leaks, tank releases, dike
leaks, a tanker truck release, and underground storage tank (UST) leaks discovered upon UST
removal. Released products have included diesel fuel, kerosene, gasoline, virgin oil, and heating
oil. A summary of past Site release incidents, as documented in historical Site documents
submitted to NCDENR, is presented on Table 3. Figure 6 presents the location of each release
with reference numbers corresponding to numbers presented on Table 3.
1.5.2 Remediation Activities
Remediation activities at the Site have included soil excavation, groundwater pump and treat,
dual phase vapor extraction, and groundwater recovery and treatment through an interceptor
trench. A permeable reactive barrier (PRB) was installed in February 2005 downgradient of Tank
118 in the eastern area of the Site. In -situ submerged oxygen curtain (ISOC®) units are currently
installed in the northwestern area of the Site (the existing ISOC® is discussed further in
Section 1.6). Absorbent socks have historically and are currently being used to detect and

SECTIONONE INTRODUCTION
recover LNAPL in select Site monitoring wells. A summary of Site environmental remediation
activities conducted in response to the various historical facility product releases is present on
Table 4. Locations of Site remediation activities are indicated on Figure 7.
1.6 EXISTING ISOC® SYSTEM
The layout of the existing ISOC® system is shown on Figure 8. ISOC® devices are installed in
six existing monitoring wells along the northwest terminal boundary (MW-02, MW-19, MW-36,
MW-38, MW-39 and MW-41) that span the width of the current plume of elevated constituent of
concern (COC) concentrations. The wells have an average spacing of approximately 20-feet
perpendicular to the apparent direction of groundwater flow. The ISOC® devices are supplied
oxygen from two, 200 cubic feet, oxygen cylinders located within a metal warehouse adjacent to
the ISOC® wells (Figure 8). Oxygen feed lines (1/4-inch I.D. polyethylene tubing) are connected
to the ISOC® devices through PVC conduit. Oxygen is injected in to the subsurface in each of
the ISOC® wells under injection permit No. WI0300106 issued on December 31, 2007 by the
NCDENR Division of Water Quality.
Following startup of ISOC® system in November 2005, groundwater dissolved oxygen (DO)
measurements have been measured in the ISOC wells and other surrounding monitoring wells on
a routine basis. ISOC® well gauging data is listed in Table 5. System tubing to all wells was
replaced in late March and early April of 2009 due to previously observed damage.
1.7 SEMI-ANNUAL GROUNDWATER SAMPLING RESULTS
Semi-annual groundwater sampling events are conducted at the Site in accordance with the
NCDENR-approved August 2005 Site groundwater monitoring plan, including sampling of the
ISOC® system monitoring wells and additional monitoring wells. The most recent report
submitted to NCDENR was the December 2011 semi-annual groundwater monitoring and
remediation report (URS, 2009). This CAP Addendum was developed utilizing all available
groundwater elevation and groundwater sampling data up to and including the December 2011
monitoring event.
A water -table contour map based on the December 2011 site groundwater levels is provided as
Figure 9. The December 2011 water -table contour map indicates a generally southern direction
of groundwater flow. Site water -table contours and apparent groundwater flow directions for
December 2011 are consistent with previous monitoring events. Historical groundwater elevation
data are included in Appendix B. December 2011 groundwater isoconcentration contour maps
for benzene, toluene, ethylbenzene, and xylenes (BTEX), methyl tertiary butyl ether (MTBE),
naphthalene, 1,2 dichloroethane (1,2-DCA), and isopropyl ether (IPE) are provided as
Figures 10 through 17, respectively. Historical analytical data is included in Appendix C. Field
parameter measurements (pH, dissolved oxygen (DO), specific conductance, and temperature)
for the December 2011 groundwater monitoring event are included in Appendix D.
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 1-5

SECTIONONE INTRODUCTION
1.8 EVALUATION OF GROUNDWATER SAMPLING DATA
Groundwater concentrations are variable across the site. Several groundwater plumes can be
identified based on historical groundwater data. A side by side comparison of historical
isoconcentration maps for numerous past sampling events for benzene, MTBE, naphthalene and
1,2-DCA are included in Appendix E to visually aid in determining the movement and/or
stabilization of the plumes. Currently, the major plumes are:
• In the eastern portion of the Site in the vicinity of Tank 118 and surrounding area.
The PRB (installed in February 2005) is downgradient of this plume.
• In the northwestern portion of the Site from approximately the truck loading rack to
the western property boundary and north (uphill) of the ASTs.
• In the southwestern corner of the site. This plume is related to a pipeline release
currently being remediated by a separate party.
Historical analytical data was further evaluated to determine the most cost-effective remediation
system modification. In order to synthesize the large amount of analytical data for the Site,
monitoring wells were grouped into five geographic areas (Figure 18). For each analyte, all
positive results (nondetects excluded) for each group for each sampling event were averaged
using the geometric mean of the results'. The resulting data were plotted on time -trend graphs to
determine if trends to variations in the data can be identified. The resulting graphs are included
in Appendix F.
Graph F-1 shows the data for the entire Site. Each symbol on the graph represents the geometric
mean concentration of one analyte during a sampling event (several day events are plotted as
one). The line represents a straight-line best fit (on a semilog graph) of the data from January 1,
2000 to the present2. These results show an overall decrease in concentrations of all constituents
analyzed for the entire site for the last eight years.
A similar analysis was performed for the five geographic areas of the Site shown on Figure 18
• Area 1 — East Side (Graph F-2): The wells in the vicinity of the Tank 118 release
show a pronounced decrease in concentrations for all constituents except isopropyl
ether (IPE), which decreased only slightly.
• Area 2 — Truck Loading Rack Area (Graph F-3): The wells in the truck loading
rack area have historically had concentrations much lower than the three major plume
1 The geometric mean is calculated by taking the logarithm of each value, averaging these log values, then raising 10
by the log mean as the exponent. This method is more accurate than a simple average when using values that span
more than one order of magnitude because it gives all values an equal weight.
2 Data prior to 2000 were excluded from the best -fit analysis to better determine the effectiveness of current
remediation activities.

SECTIONONE INTRODUCTION
areas. However, these wells show a pronounced decrease in concentrations for all
constituents except ethylbenzene, which decreased only slightly.
• Area 3 — Central/Upgradient Area (Graph F-4): This area includes the wells from
the northwestern corner of the site to near the center of the Site, but upgradient of the
ASTs. This area includes some of the highest concentrations on the Site, and was
previously remediated by the pump -and -treat and dual -phase systems. Constituents
show varying trends in this area. Concentrations of 1,2 DCA are decreasing slowly.
Concentrations of benzene, MTBE, and IPE are nearly stable. Concentrations of
ethylbenzene, naphthalene, toluene, and xylenes are increasing.
• Area 4 — Central/Downgradient Area (Graph F-5A): This area includes the wells
from near the center of the Site to the southern property boundary, and includes much
of the AST area. Concentrations in this area are much lower than the major plume
areas, and are generally stable to decreasing slightly. Concentrations of some analytes
showed an increase during 2005 and 2006, but appear to be decreasing since then
(Graph F-5B). The cause of this increase is not known, but may be a delayed
response to the Curtis Oil spill that occurred at the truck loading rack in December
2003.
• Area 5 — ISOC® Area (Graph F-6A): This area includes wells near the western
property boundary. This area includes some of the highest concentrations on the Site,
and was previously remediated by the pump -and -treat and dual -phase systems. These
wells show an apparent decrease in concentrations for all constituents. To determine
the effectiveness of the ISOC® system, the best fit was divided to show trends before
and after the ISOC® system was started in December 2004 (Graph F-6B). This plot
shows variable, with possibly some increasing, trends from 2000 through 2004, but
decreasing trends for most constituents from 2005 through 2008. This suggests that
the ISOC® system may be effectively remediating this portion of the Site.
The groundwater sampling data evaluation presented above shows that concentrations are stable
or decreasing over most of the Site. The only area with persistent elevated concentrations is the
central/upgradient area. The central/upgradient area wells generally correspond with the elevated
COC concentrations comprising the northwestern plume discussed previously. The extent of this
plume, determined from wells containing elevated COC concentrations, is generally
encompassed by the 1.0 µg/L benzene isoconcentration contour illustrated on Figure 10. The
most elevated COC concentrations were detected along the center of the plume in monitoring
wells UW-10, MW-51, MW-2, ES-05SR, MW-36, MW-44, MW-21, and MW-19.
Consequently, the central/upgradient area, specifically the area of elevated COC concentrations
within the northwestern major plume, is the target area for remediation.

1.9 RECEPTOR INFORMATION
1.9.1 Water Wells and Surface Water
Water supply wells in the Paw Creek terminal area are currently addressed in the context of all
terminals located in the area. There is one known potable water supply well within 1,500 feet and
downgradient of the Site. The well is located at 6516/6518 Freedom Drive and is approximately
1000 feet from the targeted remediation area. No public water supply systems were located
within a 1,500 foot radius of the Site (CRA, 2004). An intermittent stream is located southwest
of the Site approximately 700 feet from the targeted remediation area.
1.9.2 Migration Pathways and Subsurface Structures
Subsurface structures including petroleum pipelines, DPVE system conveyance lines, storm
water drainage lines, underground low -voltage communication cables are located on the Site.
Stormwater drainage lines carrying water off -site are located along the southeastern boundary of
the Site. Major utilities (i.e. sanitary sewer and water) are located along Mount Holly Road,
upgradient of the Site. Groundwater ranges between 5 and 15 feet below ground surface at the
Site. As such, impacted groundwater may be in the vicinity of buried utilities. No known
underground utilities, other than the conveyance lines for the former DPVE system, are located
within the vicinity of the targeted remediation area. No basements are known to be located on the
Site (Abernathy, 2009).
1.9.3 Contaminant Exposure Risks
Based on residual hydrocarbon impacts at the Site described in previous sections, the following
potential transport mechanisms for COCs at the Site are recognized:
1. Dissolved -phase COC transport in groundwater
2. Discharge of COCs in groundwater to surface water
3. Leaching of COCs from "smear zone" to groundwater
1.9.4 Routes of Exposure
Based on Site and surrounding area characteristics and the reasonable foreseeable future uses of
the Site and surrounding properties, the following potential routes of exposure to COCs from the
Site are recognized:
1. Incidental ingestion and dermal absorption of COCs, or ingestion of aquatic
organisms, from potentially impacted surface water.
2. Ingestion of COCs via future potable well water user at the Site.
3. Indoor and outdoor direct inhalation of vapor -phase COCs during implementation of
corrective action or possible redevelopment of the site.

SECTIONONE INTRODUCTION
1.9.5 Potential Receptors
There appear to be no completed pathways between impacted groundwater and potential
receptors, but based on the reasonable future use of the Site and surrounding area, the following
potential receptors may exist:
1. Construction workers and employees disturbing the subsurface (ingestion, inhalation,
and dermal absorption of COCs from impacted soils and/or groundwater during
construction).
2. On -site employees (indoor/outdoor inhalation of vapor -phase COCs).
3. Future on -site personnel (ingestions/dermal absorption of COCs in groundwater
and/or surface water, and indoor/outdoor inhalation of vapor -phase COCs).

SECTIONTWO
REMEDIAL STRATEGY
2.1 CAP ADDENDUM OBJECTIVE
The primary target area for remediation is the central/upgradient area, specifically the area of
elevated COC concentrations within the northwestern major plume. The recommended course of
action to satisfy the requirements of the NORR is to install and operate active remediation along
the center of the northwestern plume. The objective of the CAP Addendum is to reduce
groundwater concentrations comprising the northwestern plume and to continue the offsite
migration mitigation efforts in the targeted area. Treatment will be applied to the saturated
overburden soils. Vadose zone soils are not targeted because of the high water table and the
assumption that the majority of impacts are currently located within the saturated zone or within
"smear zone" soils. Impacts within competent bedrock will also not be treated due to the
difficulty accessing this area for treatment. However, treatment of the saturated overburden will
decrease the source of COCs so that as concentrations decrease naturally in underlying bedrock
they are less likely to be replenished by overlying COC concentrations.
Groundwater impacts will be monitored during remediation with the goal of reducing elevated
concentrations. The performance of the corrective action will be assessed after 3 years of
operation and recommendations for continued operation and monitoring will be provided.
2.2 EXTENT OF CONTAMINATION
The primary COCs present in the groundwater are BTEX, MTBE, naphthalene, 1,2-DCA, and
IPE. The contaminant mass of petroleum compounds within the northwestern plume was
estimated from December 2008 groundwater assessment data. Estimated contaminant mass
calculations are provided in Appendix G. The plume was assumed to extend to 50 feet below
ground surface (bgs) due to existing, but relatively lower, concentrations within DW-01 and
ES-05DR. The total contaminant mass in the subsurface is based on combining the mass
estimates for each phase: saturated adsorbed phase, dissolved phase, and free phase (LNAPL).
The mass of LNAPL was assumed to be zero. The estimated contaminant mass dissolved in the
groundwater was calculated as 221 pounds. Based on the assumption that the saturated adsorbed
mass is approximately ten times the dissolved mass, the contaminant mass in the saturated soil is
estimated at 2,210 pounds. Consequently, the total estimated contaminant mass within the
northwestern plume is approximately 2,430 pounds.
2.3 REMEDIAL CONSIDERATIONS
There are several logistical issues to be considered in selecting, designing and implementing a
remedial action in the targeted remediation area. The area is generally flat, but slopes southward
at its southern end where it is terraced with numerous ASTs and above -ground piping. The area
contains several buildings, above -ground pipes, and work areas. Most of the area is asphalt,
concrete pavement or covered by gravel. The water table in the area is approximately 5 to 10 feet
below ground surface. Access to some areas is limited or impractical due to the existing

SECTIONTWO REMEDIAL STRATEGY
structures and layout. The area is located within a high traffic section of an operational terminal
Treating groundwater in the targeted area poses several limitations including:
• Groundwater is present at approximately 5 to 10 feet bgs
• Above ground product piping and electrical lines in the area of remediation
• Terminal structures, including occupied buildings, in the area of remediation
• Ground disturbance would require removal and replacement of asphalt and/or
concrete
• Regular traffic in the area of remediation
• Saprolite / bedrock interface is not uniform across the site
2.4 REMEDIATION TECHNOLOGY EVALUATION
2.4.1 Technology Screening and Pilot Study
A potential technology screening table is included as Table 6. The technologies presented on the
table include biosparging, continuous ozone injection, continuous ozone and peroxide injection,
ISOC®, and BOS 200 Trap and Treat® injection. Pump and treat and DPVE were not considered
because they were utilized in the targeted remediation area from 1985 to 2000 and elevated COC
concentrations have persisted. In addition, air sparge combined with soil vapor extraction (SVE)
was not considered because of historical high water table elevations, particularly in the eastern
portion of the targeted area (e.g. MW-21, MW-26, UW-8, and UW-10), make soil vapor
extraction impractical.
Based on the evaluation presented on Table 6, continuous ozone injection, ozone and peroxide
injection, and Trap and Treat have the highest capital costs. All options other than MNA are
implementable and may be effective at the Site. Other than MNA, the least expensive but
potentially effective alternatives are a biosparge system installation or an expansion of the
current ISOC® system. Ozone or peroxide injection, Trap and Treat® injection, and ISOC®
system modification will require an underground injection control (UIC) permit through
NCDENR. A permit exists for the current ISOC® system (No. WI0300106) and would be
modified if the system is expanded. A modified ISOC® UIC permit is anticipated to be the most
easily obtained of the options evaluated. A UIC permit is not required for air injection (i.e.
biosparging or air sparging).
2.4.2 Previous Pilot Test(s)
2.4.2.1 CIA Pilot Test 2002
CRA performed an air sparge and SVE pilot test in two areas of the Site (Area 1 and Area 2) in
June 2002. Area 1 was located along the western boundary within the targeted remediation area
and Area 2 was located on the eastern boundary of the Site near the PRB. Results from CRA
pilot test and implications for proposed system design are listed below.
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 2-2

SECTIONTWO REMEDIAL STRATEGY
• The Area 1 SVE test showed a vacuum radius of influence (ROI) of 17.5 ft. The
limited ROI would make air sparging vapor control with SVE difficult. Additionally,
because water table elevations are as high as 5 feet bgs in portions of the targeted
remediation area, use of SVE is not technically sound or cost efficient due to the
handling of water.
• The pilot test report included a calculated intrinsic permeability of 1.5x10-9 cm2 (0.15
darcy). This represents a lower permeability than the permeability of 2.95 darcy
calculated based on previously reported hydraulic conductivities (Section 1.2) and
confirms that the permeability is low to moderate in the targeted treatment area. The
permeability indicates that air sparging or biosparging is feasible based on established
site condition criteria but indicates that effectiveness may be limited by permeability
in the area.
• The air sparge test in Area 1 resulted in an estimated pressure ROI of approximately
30 feet (an ROI of 74 feet was seen for Area 2). This ROI is large enough to be
practical for use at the Site.
• The Area 1 air sparge test showed an injection pressure at the well of approximately
10 pounds per square inch (psi) for flows of approximately 5 cubic feet per minute
(cfm) or less.
• Vapor monitoring in surrounding monitoring wells during the Area 1 air sparge test
showed volatile organic compound (VOC) vapors as high as 1000 ppm during
sparging. Detected VOCs were generally higher during higher air sparge flows (7
cfm) and were generally lower (around 30 ppm) during lower flows (3-5 cfm).
Biosparging would operate at <3 cfm.
• DO concentrations decreased during the Area 1 air sparge test and increased during
the Area 2 air sparge test. This indicates that the Area 1 air sparge pilot test did not
show the intended result of biosparging. However, increases in Area 2 DO
concentrations were significant and suggest that biosparging can be successful and
that the Area 1 result may have been incidental. In addition, breakthrough appears to
have occurred at the 5 minute mark based on observed PSI in Area 1, which suggest
that soils are permeable.
2.4.2.2 URS Pilot Test 2010 2011
URS performed an air sparge and anerobic bioremediation pilot test in several areas of the Site
(Area 2 and Area 3) from June 2011-February 2012. A fully detailed description of the two pilot
tests are presented in Appendix H.
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 2-3

SECTIONTWO REMEDIAL STRATEGY
Biosparging Test Results
• The biosparging test results were consistent with the results of the CRA pilot test in
as far as the anticipated radius of influence and injection pressures. The test indicated
that one might expect a 20 to 25 foot radius of influence within the treatment areas at
pressures ranging from 16 to 25 psi and flows averages 2-3 scfm.
• The test did illustrate potential preferential pathways that can distribute air other
portions of the site.
• VOC analysis for the biosparge testing showed an increase in concentrations from the
baseline sampling to sampling conducted in December 2010 and January 2011.
Increased concentrations in Area 3 were likely caused by shutdown of the ISOC
system during pilot study biosparge activities. However thie pilot test was only
performed for 3 months and while concentration decreases were not exhibited the
area around the injection well maintained dissolved oxygen within the aquifer at
levels able to support microbial growth.
• The long term biosparge test appeared to indicate that VOC concentration reduction is
possible over time.
Sulfate Injection Results
• Analytical results showed that VOCs in monitoring wells MW-65, MW-21, and MW-
26, wells in the immediate areas of the sulfate injections, have decreased while
inorganic concentrations have generally increased or remained relatively unchanged
from baseline results through July 21, 2011 results. Monitoring well MW-68, which
is within the boundary of the Area 2 injection, showed an increase in VOCs.
• Analytical results from June 8, 2011 sampling showed the greatest difference from
the baseline sample results. Subsequent sampling events show results moving closer
to baseline reporting.
• Bromide was reported in monitoring wells MW-65 and MW-68 during sampling
conducted following injection events. All baseline samples and pilot study samples
were non -detect for bromide in all sampled wells except pilot study samples of MW-
65 and MW-68, which are located within the injection areas. Correlating
concentrations of sulfate were also detected in monitoring wells MW-65 and MW-68
following injection events. Initial sulfate concentrations were lower than expected
following the injection events in both Areas 1 and 2. The sulfate concentrations also
appeared to decrease steadily over the post -injection sampling events in correlation
with the decreasing bromide concentrations indicating that physical processes present
in the aquifer are more dominant than biological processes and calls into question the
efficacy of the sulfate injection technology.

SECTIONTWO REMEDIAL STRATEGY
2.4.3 Selected Technology and Further Evaluation
Biosparging was selected for treatment of the targeted remediation area. General descriptions of
the technologies are presented on Table 6. The applicability of the technologies was further
evaluated using observed Site conditions and the results of an air sparge pilot test performed by
Conestoga Rovers and Associates (CRA) in 2002 (CRA, 2002).
2.4.3.1 Site Conditions
Site conditions were evaluated to assess the applicability of the selected remediation technology.
The following criteria were evaluated based on established criteria for required Site conditions
for the selected technologies (USEPA, 2004).
Site COCs should be determined to be aerobically biodegradable. All COCs for the Site have
been shown to be aerobically biodegradable.
Site permeability will affect air sparging effectiveness. A higher permeability will allow greater
air flow. Soil conditions at the Site should at least exhibit moderate permeability (approximately
greater than 0.1 darcy (USEPA, 2004)). The average permeability at the Site is approximately
2.95 darcy (Section 1.2) but may be less in some areas.
The groundwater pH should be between 6 and 8 for effective aerobic degradation (USEPA,
2004). During the December 2011 sampling event, 45 of the 48 samples in which pH was field
measured had pH between 6 and 8 (Appendix D). Of the samples outside the range, only one
was above 8.5 and none were below 5.
The groundwater temperature should be between 10°C and 45°C for effective aerobic
degradation (USEPA, 2004). During the December 2011 sampling event all 46 of the samples in
which temperature was field measured had temperature between 10°C and 45°C (Appendix D).
Furthermore, the temperatures were generally around 18°C which is within the optimum range
for microbial activity.
In addition, historic DO data collected suggests that supplying oxygen to the targeted
remediation area is a valid strategy. As shown on Figure 19, DO concentrations appear to be
lowest in the area of the COC plume, with the exception of the western end of the plume, where
the existing ISOC® system is operating. The depleted DO concentrations suggest that aerobic
degradation is already occurring at the edges of the plume but is limited by the available oxygen.
Supplying oxygen to the center of the plume should allow aerobic bacteria to thrive and will
accelerate degradation of the targeted COCs.
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 2-5

SECTIONTHREE PROPOSED CORRECTIVE ACTION
The corrective action proposed for the Site is to be accomplished by implementing the following:
• Biosparging to treat dissolved -phase groundwater impacts and to minimize
contaminant migration.
• Long term groundwater monitoring to observe the effectiveness of enhanced aerobic
degradation at the Site. Groundwater monitoring will include the evaluation of DO to
monitor the effect of the proposed corrective action.
Biosparging will be utilized along the two "axes" of the northeast COC plume to mitigate off -site
migration of the plume. Figure 20 illustrates the location of the proposed well network. Based
on both air sparging pilot test, a conservative ROI of 20 feet will be utilized for design of the
proposed remediation system. The well network illustrated on Figure 20 includes 19 remediation
wells with an estimated 20 foot ROI. Conveyance piping will be installed to allow for the
potential future expansion of up to five additional remediation wells in the northern portion of
the plume.
3.1 SYSTEM COMPONENTS
Implementation of the system is described below. The main components of the proposed
biosparging system are as follows:
• Air compressor
• Coalescing filters
• Air supply piping
• Biosparging wells
• Control panel including remote access
• Various system appurtenances, including flow meters and pressure, temperature,
and flow gauges
3.1.1 Process Flow
Conceptual design schematics for biosparging systems, including a conceptual process and
instrumentation diagram, are included in Appendix I. Worksheets for the preliminary sizing of
the system components are provided in Appendix J. The calculations show a predicted injection
pressure requirement at the well of approximately 15 psi, (similar to the results of the 2002 CRA
pilot test. The total required pressure at the manifold, including supply piping and fitting friction
loss and a 25 percent safety factor, will be approximately 25 psi. An air compressor will be
selected that is capable of providing approximately 70 scfm at 25 psi. Pulsing will be utilized to
operate only half of the biosparging wells at any given time. This schedule will allow the
biosparging system to reach equilibrium and optimize influence while reducing the risk of flow
channelization.
P:\BP\Projects\Terminals\4762\5.0 Deliverables \5.1 Draft - Interim Deliverables\CAP Modification Document 6-1-2012\4762 CAP Addendum 061512.doc 3-1

SECTIONTHREE PROPOSED CORRECTIVE ACTION
Air will be supplied by an air compressor and conveyed to the biosparging wells through a series
of supply lines. The air supplied by the compressor will pass through two coalescing filters to
remove any liquid oil, water aerosols, and fine particulate matter. The filters will be used to
provide redundancy and eliminate the potential of introducing any oils into the wells. The control
panel will contain a programmable logic controller (PLC) that will allow timed operation of
individual sparge wells. The system will allow for remote access to check the compressor's and
sparge well operational status.
3.1.2 Trenching and Well Installation
The conceptual design conveyed in this document envisions placing the biosparging wells at the
intersection of the partially weathered bedrock and the more competent bedrock, or
approximately 30 feet deep in most portions of the site. Prior to installation of biosparging wells
a short duration tracer gas study will be performed to verify vertical influence of the air sparging
wells. Based on these results final depths of the biosparging wells will be finalized in the bid
plans and specifications.
Prior to installing vertical wells and trenching, utility clearance will be performed to locate any
on -site underground utilities. Conveyance piping for the former DPVE system will likely be
crossed during trenching for the proposed system. The former system has been abandoned and
the lines are not under vacuum. DPVE piping will be cut and capped where crossed if necessary.
Biosparge wells will be set as deep as possible above competent bedrock. Biosparge wells will
contain at least one foot of screen and based on the approximately 25 foot water column
thickness between bedrock and the water table (see Figures 4 and 5), there is no potential for
screen to be exposed to the vadose zone during operation.

SECTIONFOUR MONITORING PLAN
4.1 GROUNDWATER MONITORING
Semi-annual groundwater monitoring of the Site will continue in accordance with the NCDENR-
approved August 2005 Site groundwater monitoring plan. MW-47 and MW-55 will be sampled
on a semi-annual basis in addition to the currently sampled wells. Analytical parameters for all
wells will include BTEX, MTBE, naphthalene, IPE, and 1,2-DCA.
Additional analytical parameters (alkalinity, methane-ethane-ethene (MEE), nitrate,
orthophosphate, sulfate, ammonia-N, and total organic carbon (TOC)), and field parameters
(ferrous iron and oxidation reduction potential (ORP)) were collected at monitoring wells ES-01,
UW-10, MW-51 and ES-38 during the June 2009 groundwater monitoring event to establish
baseline conditions prior to implementation of the CAP Addendum. The additional parameters
will continue to be monitored at ES-01, UW-10, MW-51 and ES-38 during each groundwater
monitoring event following CAP implementation.
4.2 SYSTEM MONITORING
Monthly operations and maintenance (O&M) visits will be made after system startup and
shakedown. All applicable operational parameters will be recorded during each O&M event.
Filters will be checked and cleaned/replaced as necessary. Required maintenance will be
performed on all system components per manufacturer's recommendation.
Performance monitoring for system effectiveness will primarily be through the measurement of
dissolved oxygen concentrations within the groundwater. DO measurements will be collected
periodically during the normal operations and maintenance of the system the frequency of which
will be defined in an O&M plan.
4.3 REPORTING
The current semi-annual groundwater monitoring reporting performed for the Site will be
submitted to NCDENR after each groundwater monitoring event. The data transmittal will
include:
• Description of sampling activities with a discussion of any changes from the previous
monitoring event or abnormal observations
• Analytical data summary tables and figures for groundwater
• Laboratory Analytical Reports
• Tabulated DO measurements
• Tabulated biosparge O&M data (system performance, pressure, flow)
• Recommendations for monitoring and operational changes

SECTIONFOUR MONITORING PLAN
4.4 ESTIMATED SYSTEM OPERATION SCHEDULE
The estimated system operation time is 4 years. Actual system operation time will be based on
system performance. Uncertainties associated with this estimate include variations in Site
conditions and Site assessment limitations, such as water level fluctuations and site geology
characterization, and other environmental factors. System operations will be revaluated
approximately three years after the beginning of system operation, and recommendations for
continued operation and monitoring or system modifications will be submitted to NCDENR.

SECTIONFIVE SCHEDULE
5.1 SCHEDULE FOR IMPLEMENTATION
A general schedule for implementation of the remedial activities described above is shown on
Table 7. Upon approval of the CAP Addendum by NCDENR, planning and detailed system
design will begin. The following is a list of activities to be completed prior to system start-up.
• Design and Planning
• Prepare Detail Design and Prepare Technical Specifications for System Equipment
and Installation
• Select Drilling Contractor
• Permitting
• Purchase System Equipment and Materials
• System Construction
• Drilling and Well Installation
• Trenching and Pipe Installation
• Equipment Installation
• O&M manual development
• System Start-up / Shakedown
5.2 PERMITTING
The current UIC permit for the ISOC wells will be terminated. Mecklenburg County requires air
permits for discharge of toxic air pollutants. Typically, a discharge permit or permit exception is
obtained for air sparge and soil vapor extraction systems. In the case of biosparge systems, the
vapor discharge is small, difficult to accurately quantify, and is not limited to a single discharge
point. However, an air permit exemption should be obtained for active biosparging from
Mecklenburg County Air Quality (MCAC). Submittal of a letter to MCAC describing the system
and process commonly results in an air permit exception for sparging systems (Rayfield, 2009).
The letter will be submitted 90 days prior to biosparge system installation if applicable. In
addition, an application for a well permit will be submitted to Mecklenburg County Groundwater
and Wastewater Services for each well installed during CAP implementation. Finally, all
required permits for fire, electrical, building, and construction related to the remediation
equipment compound will be obtained prior to system installation.

Installation of
Biosparge
System
Biosparging is a well developed technology used to effectively remediate
dissolved phase groundwater VOC contamination. Biosparging involves
injecting compressed air into the subsurface at low flow (less than 5 cfm) to
reduce groundwater concentrations. Biosparging is designed to provide the
majority of treatment through increased biological activity due to increased
oxygen levels in the aquifer. Due to the low design flows, physical removal
of contaminant mass through mass -phase transfer within the aquifer matrix
is minimal, and vapor containment (soil vapor extraction) is not typically
required.
•
This system could be easily implemented at the site. Based on
conservative assumptions and using the design parameters from the
installation of numerous systems, the system could be implemented
by procurement of a relatively small air compressor and installation
of approximately 17 wells. Wells can likely be installed in
accessible locations with the necessary design spacing. Trenching
to each well may present a minor obstacle but is possible based on
an initial assessment of the targeted treatment area. An
underground injection control permit would not be required.
Biosparging is a proven technology at reducing
concentrations of dissolved organics at petroleum sites.
Effectiveness of biosparging would vary based on the
increase microbial activity.
This estimate is based on the installation of 17 biosparging wells and
the installation of 600 linear feet of trench line, procurement of an
adequately sized air compressor/blower to supply air for the sparging
sells.

Ozone
(Continuous
System)
This technology involves the installation of in -situ injection points for the
application of ozone. The technology is a variation of in -situ chemical
oxidation. The ozone oxidizes the contaminants and degrades into oxygen,
thereby increasing aerobic biological activity. One of the advantages of this
type of system is that it continuously injects the ozone into the subsurface
instead of relying on one-time injections for contact.
While a relatively new technology in the environmental remediation
field ozone generation and application is well known in other
industries. Given the right access the system is readily
implementable. The major obstacles to installation are to obtain
underground injection control permits for ozone. However, the
product does not normally require in depth review by the State
because the materials are not pathogenic. The system requires
operation and maintenance but is generally comparable to other
continuously operating systems (biosparge and ISOC®).
Ozone injection has been proven to be particularly
effective at achieving significant concentration reduction
in a short period of time. It is an aggressive remediation
technology that does not depend on microbial activity.
However, an added benefit of ozone injection is that ozone
quickly degrades into oxygen thereby leaving a highly
aerobic environment that can be conducive to aerobic
degradation polishing of the resulting lower concentrations
of dissolved phase constituents.
This estimate is based on the installation of 8 ozone injection points

Ozone /
Peroxide
Injection
(ContinuousOversight
System)
This technology involves the installation of nested in -situ injection points
for the application of hydrogen peroxide and ozone. The technology is a
variation of in -situ chemical oxidation. The system continuously injects the
ozone and peroxide into the subsurface instead of relying on one-time
injections for contact. The ozone and peroxide oxidizes the contaminants
and the ozone degrades into oxygen, therebyincreasingaerobic biological
g yg g
activity. When the ozone comes in contact with the peroxide the reaction
forms hydroxyl radicals that have the required energy to break down more
recalcitrant compounds such as MTBE and Acetone.
While a relatively new technology in the environmental remediation
field ozone generation and application is well known in other
industries. Given the right access the system is readily
implementable. The major obstacles to installation are to obtain
underground injection control permits for ozone and peroxide.
However, theproducts do not normallyrequire in depth review bythat
q p
the State because the materials are not pathogenic. The system
requires operation and maintenance but is generally comparable to
other continuously operating systems (biosparge and ISOC®).
Ozone and peroxide injection has been proven to be
particularly effective at achieving significant concentration
reduction in a short period of time. It is an aggressive
remediation technology that does not depend on microbial
activity. However, an added benefit of ozone injection is
ozone quicklydegrades into oxygen therebyleavinga
g yg
highly aerobic environment that can be conducive to
aerobic degradation of the resulting lower concentrations
of dissolved phase constituents.
This estimate is based on the installation of 8 ozone injection points
and the installation of 550 linear feet of trench line, and procurement of
an adequately sized ozone production system.

ISOC® System
Expansion
This technology involves installation of in -situ submerged oxygen curtain
(ISOC®) units and connection the units to aboveground oxygen cylinder.
Units are installed in existing or remediation specific wells and deliver
oxygen to the groundwater through hydrophobic microporous hollow fibers
that allow the unit to supersaturate the groundwater with dissolved oxygen.
The increased oxygen levels stimulate aerobic biological activity to degrade
petroleum hydrocarbons.
This system expansion would be easily implemented. Based on
conservative assumptions and using the design parameters from the
installation of the numerous systems, the system could be
implemented by procurement by upgrading the current
aboveground oxygen distribution equipment and the installation of
approximately 17 wells. Wells can likely be easily installed in
accessible locations. Trenching to each well may present a minor
obstacle but is possible based on an initial assessment of the
targeted treatment area. A modification of the current underground
injection control permit will be required. ISOC® systems are
relatively simple and easy to maintain.
ISOC® is a proven technology to reduce concentrations of
dissolved organics at petroleum sites. The current ISOC®
system, which currently includes wells downgradient of the
targeted treatment area, appears to have been effective at
reducing concentrations in that area. Effectiveness of
ISOC would vary based on microbial activity.
This estimate is based on the installation of 17 additional ISOC
injection wells, installation of trenching and backfill, procurement and
installation of the ISOC head works.

Trenching and Install: $70,000

Trap and

Injection
This technology involves "one-time" injections of a specially -formulated
blend of activated carbon, sulfate reduction media, micronutrients, and
facultative microbes. The mixture, BOS 200®, is designed to capture COCs
and degrade them biologically.
This technology could be implemented at the site. Desirable
spacing of injection points can likely be achieved in accessible
locations within the targeted treatment area. However the injection
will require an underground control permit that may be scrutinized
by the State due to the injection of microbes. The technology
would be difficult to implement at the site because of the heavy
traffic within the targeted area and large number of injection points
required. The technology would not require continued operations
and maintenance activities.
BOS 200® has been reportedly effective at significantly
reducing concentrations at petroleum impacted sites. The
technology is an aggressive on time injection that provides
short-term treatment through adsorpotion of contaminants
and long-term biological treatment.
This estimate is based on 216 injection points with injection at eight
intervals and the injection of 45,000 pounds of BOS 200®.
Capital Costs: BOS 200 Injection: $455,000
Oversight Services: $16,000
Total Capital Costs: $471,000

Dear Mr. Taylor:

Incident Numbers: 6771, 15159, 15618,
17002, 17262 & 20622
Ranking: H250D
The Active Remediation Monitoring Report (ARMR) received on April 6, 2009 has been
reviewed by the UST Section, Mooresville Regional Office (MOR). The review indicates that:
1. Welts ES-15, 23, 32, 33 & 34 were repaired in December 2008;
2. An obstruction was removed from well VE-02;
3. Tubing for the ISOC wells was scheduled to be replaced in March 2009; and,
4. Your consultant requested a site meeting to discuss potential modification in the CAP
required in the October 14, 2008 Notice of Regulatory Requirements.
Current travel restrictions made a site meeting between the UST Section incident
manager, currently myself, and URS Corporation — North..Carolina (URS) representatives
infeasible. In telephone discussion, Margaret Ness=of URS indicated that biosparging or ISOC
technology were being considered as remediation technologies for the central plume area
(centered on UW10 and MW21), and that implementation of a treatment system in the area of
the eastern plume was not recommended.

I concur with URS's recommendation to implement active corrective action in the central
plume area at this time and to continue to monitor the eastern plume. A revised Corrective
Action;Plan (CAP) with a schedule for; implementation must be received by this office within 75
days of the date,of.this notice.-. Failure to implement the plan and schedule in the Manner and
time cpprifiMrl may raenit in t1hP acceeempnt of civil r naltiae and/nr the lice of nthrr Pnfnrr.Pmpnt
mechanisms.
Because a release or discharge has been confirmed, a Licensed Geologist or a
Professional Engineer, certified by the State of North Carolina, is required .to .prepare and certify
all reports submitted to the Depaitnient in accordance with 15A NCAC 2L .0103(e) and 2L
.0111(b).
If you have any questions regarding the actions that must be taken or the rules mentioned

CONTAMINANT MASS CALCULATION

Contaminant Mass Calculation
Project:
BP Terminal 4762 Prepared by: CJK
Charlotte, North Carolina Checked by: JK
Objective: Estimate the mass of contaminants in the (dissolved) groundwater phase and saturated adsorbed phase in targeted remediation area plume.
Assumptions: 1. Saturated adsorbed mass is estimated at 10 times the dissolved mass
2. Concentration calculated is total of BTEX, MTBE, naphthalene, 1,2 DCA, and isopropyl ether concentrations
3. Plume area estimated as conservative area containing wells within December 2008 1 ug/L benzene contour area (Figure 10)
4. No LNAPL is present
5. Does not include contamination above the water table
Groundwater and Adsorbed Phase Mass Calculation
Area of 1 ug/I benzene isocontour (Figure 10). This area contains elevated concentrations in plume (i.e. all
Plume Surface Area = 112,757 sq ft wells listed below).
Porosity = 0.20 Conservative estimate (assumed previously to be 0.10 (CRA, 2004))
Average Water Table = 8 ft bls Approximate
Bottom of Groundwater Plume = 60 ft bls Estimated extent based on detections in bedrock wells
Average Concentration = 3.02 mg/L December 2008 groundwater sampling data, using average COC concentrations for DW-01, ES-01,
ES-05DR, ES-05SR, MW-02, MW-05, MW-19, MW-21, MW-26, MW-36, MW-39, MW-41
MW-44, MW-49, MW-51, UW-08, UW-10, VE-02 (combined BTEX+MTBE+
Naphthalene+1,2-Dichloroethane+Isopropyl ether).
Groundwater Volume (f13) = Surface Area (ft2) x Plume Depth (ft) x Porosity
Groundwater Mass (kg) = Volume (fe) x Concentration (ug/L) x (28.3 L / ft') x (1 E-09 kg / ug)

Dear Mr. Leach:
Enclosed is one copy of the 2010-2011 Pilot Study Summary — August 2011, for the BP Products
North America, Inc. bulk -fuel storage terminal (formerly Southeast Terminals) in Charlotte,
North Carolina. The report includes a summary of the biosparge and sulfate injection pilot studies
and methods which occurred in 2010 and 2011. Groundwater sampling events to monitor sulfate
injection is ongoing. The In -Situ Submerged Oxygen Curtain (ISOCTM) groundwater remediation
system remained off during the biosparge study activities, operation resumed on March 1, 2011.
If you have any questions or would like any additional information, please do not hesitate to call

SECTIONONE Introduction
On behalf of Atlantic Richfield Company (ARCO), a BP Products North America, Inc. (BP)
affiliated company, URS Corporation — North Carolina (URS) presents this progress report of
remedial pilot study activities conducted between June 2010 and July 2011 at the facility located
at 7401 Old Mount Holly Road in Charlotte, North Carolina (formerly "Southeast Terminals").
The Site has been assigned Groundwater Incident Nos. 06771, 15159, 15618, 17002, 17263,
17264, and 20622 by the North Carolina Department of Environment and Natural Resources (NC
DENR) in response to various historical petroleum product release incidents at the facility. The
Site priority ranking is currently 100B due to the presence of potable water -supply wells within a
1,500 foot radius of the Site.
The following pilot study activities have been completed at the Site through the delivery of this
report:
• Pilot Study groundwater sampling and analysis June 2010 through July 2011).
• Biosparge Pilot Study (October 22, 2010 through January 17, 2011).
• Sulfate Injection Pilot Study (May 16, 2011 through July 21, 2011).

SECTIONTWO Background
2.1 SITE LOCATION AND DESCRIPTION
Maps showing the Site area and layout are provided as Figure 1 and Figure 2. The Site is
located in the Paw Creek area of Charlotte, North Carolina, an area predominantly occupied by
petroleum terminals and light industrial facilities.
2.2 SITE TOPOGRAPHIC AND GEOLOGIC/HYDROGEOLOGIC SETTING
The Site is located in the Piedmont physiographic province, which is characterized by
moderately level interstream areas separated by broad valleys. Bedrock in Charlotte, North
Carolina is mapped within the Charlotte Belt lithologic division of the Piedmont, which includes
mafic gneisses, amphibolites, metagabbros, and metavolcanic rocks. According to the Geologic
Map of North Carolina (North Carolina Geological Survey, 1985), bedrock beneath the facility
consists of metamorphosed quartz diorite or quartzite.
Competent bedrock in the Piedmont province is typically overlain by variable thicknesses of
saprolite and soil, collectively referred to as "overburden." Saprolite consists of rock that has
been subject to chemical weathering, removing up to 60% of the rock mass by solution, but not
affecting volume (Cleaves, 1974). Saprolite commonly retains relict structures from the parent
bedrock. Thicknesses of the overburden in the Piedmont typically range from 10 to 75 feet,
depending on rock composition and topographic setting (LeGrand, 1988).
2.2.1 Significant Changes in Lithology
Based on Site boring logs, subsurface materials at the Site consist of soil and saprolite
overburden, including silty/clayey sand, sandy clay/silt, and silt/clay, overlying weathered and
competent bedrock. Bedrock, meeting the description of metamorphosed quartz diorite
referenced above, has been encountered in Site borings at depths ranging from approximately 10
to 40 feet below grade and elevations ranging from approximately 729 to 774 feet above mean
sea level (msl).
Groundwater in the Piedmont province occurs in the overburden under unconfined (i.e., water
table) conditions, and in the underlying bedrock under both unconfined and confined conditions.
Groundwater in the overburden occurs within pore spaces of the unconsolidated medium,
including relict bedrock structures (i.e., fractures, foliations, etc.). Due to the typical fine-grained
nature and low permeability of saprolite, the formation is not usually utilized for groundwater
production. Groundwater in the underlying bedrock occurs along zones of secondary porosity,
such as fractures, foliations, solution voids, etc. Most water -supply wells in the Piedmont are
completed in bedrock with surface casings extending through the overburden.

SECTIONTWO Background
2.3 SITE MONITORING WELL NETWORK
The locations of Site groundwater monitoring and remediation wells are shown in Figure 2. Site
well construction details are listed in Table 1. Total depths of Site monitoring and remediation
wells range from 7 to 110 feet below top of casings. Ten Site monitoring wells are completed in
bedrock and one Site monitoring well is completed in saprolite directly above bedrock. The
remaining Site monitoring wells are completed in the shallow overburden (i.e., water -table
monitoring wells).
2.4 SUMMARY OF LIGHT NON -AQUEOUS PHASE LIQUID OCCURRENCE
Light non -aqueous phase liquid (LNAPL) has been detected periodically in some Site monitoring
wells. Inspection and replacement of the LNAPL-absorbent socks for select wells (ES-05SR,
ES-25, ES-33, MW-12, MW-51, UW-10, and VE-02) is completed periodically. Refer to the
December 2010 Semi Annual Groundwater Monitoring and Remediation Report for specific
details.
2.5 SITE RELEASE AND REMEDIATION HISTORY
2.5.1 Historical Site Release Incidents
Historical releases at the Site have included tank overfills, pipeline leaks, tank releases, dike
leaks, a tanker truck release, and underground storage tank (UST) leaks discovered upon UST
removal. Released products have included diesel fuel, kerosene, gasoline, virgin oil, and heating
oil. A summary of past Site release incidents can be found in historical Site documents submitted
to NCDENR.
2.5.2 Remediation Activities
Remediation activities at the Site have included soil excavation, groundwater pump and treat,
dual phase vapor extraction, and groundwater recovery and treatment through an interceptor
trench. A permeable reactive barrier (PRB) was installed in February 2005 downgradient of Tank
118 in the eastern area of the Site. In -situ submerged oxygen curtain (ISOC®) units are currently
installed in the northwestern area of the Site. Absorbent socks have historically and are currently
being used to detect and recover LNAPL in select Site monitoring wells.
2.5.3 Existing ISOC® System
The existing ISOC® system includes devices installed in six existing monitoring wells along the
northwest terminal boundary (MW-02, MW-19, MW-36, MW-38, MW-39 and MW-41) that
span the width of the current plume of elevated constituent of concern (COC) concentrations.
The wells have an average spacing of approximately 20-feet perpendicular to the apparent
direction of groundwater flow. The ISOC® devices are supplied oxygen from two, 200 cubic
URSP:\BP\Projects\Terminals\476215.0 Deliverables\5.2 Final Deliverables\Pilot Study\2010-2011 Pilot Study Summary.docx 2-2

SECTIONTWO Background
feet, oxygen cylinders located within a metal warehouse adjacent to the ISOC® wells. Oxygen
feed lines (1/4-inch I.D. polyethylene tubing) are connected to the ISOC® devices through PVC
conduit. Oxygen is injected in to the subsurface in each of the ISOC® wells under injection
permit No. WI0300106 issued on December 31, 2007 by the NCDENR Division of Water
Quality.
Following startup of ISOC® system in November 2005, groundwater dissolved oxygen (DO)
measurements have been measured in the ISOC wells and other surrounding monitoring wells on
a routine basis.
2.5.4 Corrective Action Studies
In October 2008, NCDENR issued a Notice of Regulatory Requirement (NORR) requiring BP to
provide remediation system modification recommendations. Through additional correspondence
between URS and NCDENR, a revised CAP to implement corrective action in the central plume
area is to be issued. As part of CAP development, a pilot study plan of biosparge and sulfate
injection was submitted and approved in 2010. Pilot Study scope and results are discussed in
later sections of this report.

SECTIONTHREE Groundwater Sampling
3.1 GROUNDWATER SAMPLING AND ANALYSIS METHODS
Groundwater sampling activities are conducted semi-annually at the Site. Sampling events are
completed in June and December each year, in accordance with the NCDENR-approved August
2005 Site Groundwater Monitoring Plan, which include sampling the ISOC system monitoring
wells and additional monitoring wells.
Prior to collecting groundwater samples, depth to groundwater is measured in the Site
monitoring wells using an oil/water interface probe. Following well gauging, groundwater
samples are collected from the Site monitoring wells using the purge/sample method described
as follows:
1. Temperature, pH, dissolved oxygen, and specific conductance measurements are
collected in -situ prior to purging activities.
2. The monitoring wells are purged of three standing volumes of groundwater, or until
dry, using a dedicated, disposable bailer and nylon rope.
3. The groundwater samples are collected using a dedicated, disposable bailer and nylon
rope. The samples are immediately transferred to laboratory supplied containers and
placed on ice in a cooler.
Groundwater samples collected from the monitoring wells are transferred to pre -labeled,
laboratory -prepared containers and promptly placed on ice in a cooler with a temperature and trip
blank and submitted under chain of custody to Lancaster Laboratories located in Lancaster,
Pennsylvania. Samples are analyzed for benzene, toluene, ethylbenzene, total xylenes (BTEX),
methyl tert-butyl ether (MTBE), 1-2 dichloroethane (1, 2-DCA), isopropyl ether (IPE), and
naphthalene by SW-846 Method 8260B or other EPA approved comparable method. A select
number of wells are analyzed for inorganic parameters including: total calcium and total sodium
by SW-846 Method 6010B, alkalinity by SM Method 2320B, hydrogen sulfide and total sulfide
by SM Method 4500-S2F, methane, ethane, ethene (MEK) by RSK.175, orthophosphate by SM
4500EP, and nitrate and/or sulfate by EPA Method 300 as part of the Baseline and Post Pilot
Study analysis discussed in this report.
3.2 GROUNDWATER ANALYSIS VALIDATION
URS validates analytical results for the groundwater monitoring events performed at the Site.
The data review is modeled after the USEPA Contract Laboratory Program National Functional
Guidelines (NFG) for Superfund Organic Methods Data Review (EPA, June 2008) and USEPA
Contract Laboratory Program NFG Inorganic Superfund Data Review (USEPA, January 2010).
Qualitative and quantitative limitations associated with the analytical results are determined
based on the results of specific quality control (QC) criteria. Accuracy is determined from the
review of spike recoveries. Precision is based on the evaluation of laboratory and field duplicate

results. Representativeness is evaluated from the review of holding times and blank data. Sample
results are qualified based on the results of the data review process. Qualified data are valid and
usable for their intended purpose. A copy of the data validation report is available upon request.
Laboratory analytical reports for Pilot Study groundwater monitoring on January 17, June 23,
and July 21, 2011 are included in Appendix A.

SECTIONFOUR Pilot Study
4.1 SUMMARY OF REMEDIAL ALTERNATIVES PILOT STUDY
This Pilot Study is the result of two separate pilot studies in response to a Notice of Regulatory
Requirements (NORR) letter from the NCDENR. BP/URS submitted a proposed Pilot Study
Plan dated December 15, 2009, and received approval by NCDENR to implement the pilot
studies (March 5, 2010). The NCDENR NORR requested a more proactive approach to address
areas of high concentrations of dissolved hydrocarbons at the Site, specifically the area in the
vicinity of the ISOC system. The BP and URS team completed a remedial alternatives analysis
which eventually proposed performance of a pilot test utilizing biosparging and injection
technologies for comparison. Submitted in this section of the report is a summary of remedial
pilot study activities completed at the Site from June 2010 through July 2011.
4.2 BIOSPARGE AND MONITORING WELL INSTALLATION
Three biosparge test wells (AS-04, AS-05, and AS-06) and four monitoring wells (MW-65, MW-
66, MW-67, and MW-68) were installed using hollow stemmed auger drilling methods from
August 25 through August 30, 2010. An additional monitoring well, MW-69, was installed on
May 23, 2011 for down gradient groundwater monitoring for sulfate injection analysis. Boring
logs for the biosparge test wells and monitoring wells are included as Appendix B. URS
personnel contacted NC One Ca11 for location of public utilities. Taylor Wiseman & Taylor
(TWT), a private utility locate contractor, was onsite prior to drilling to mark the Site for any
private utilities near the well locations. In addition to utility locating, TWT cleared the
monitoring wells using air knife to a depth of 6.5 ft bgs. Mad Dawg Inc. was subcontracted to
perform drilling tasks as outlined below.
The biosparge wells and monitoring wells were installed at the locations shown on Figure 3.
AS-04 and AS-05 were advanced to a depth of 39 ft bgs and AS-06 was advanced to a depth of
26 ft bgs. A 5-foot length of 0.010-inch continuous slot screen, 2-inch ID, Schedule 40 PVC and
2-inch ID, Schedule 40 PVC riser was placed in the borings. The type II monitoring wells
(MW-65, MW-66, MW-67, MW-68, and MW-69) were completed to depths of 20, 15, 15, 20,
and 17 ft bgs, respectively. MW-65 and MW-68 used a 15-foot, 0.010-inch machine -slotted,
2-inch ID, Schedule 40 PVC riser, while MW-66, MW-67, and MW-69 used a 10-foot, 0.010-
inch machine -slotted, 2-inch ID, Schedule 40 PVC well screen and 2-inch ID, Schedule 40 PVC
riser.
The annular space around the well screen was filled with graded sand. A minimum 1-foot
thickness of bentonite was placed over the sand and hydrated. The remaining annular space was
filled with grout to the ground surface. A well pad and protective casing was also installed. The
wells were completed flush with the ground surface. Monitoring well MW-69 was completed as
a stick-up, finished approximately 3 ft. above the ground surface with protective casing.

SECTIONFOUR Pilot Study
Following installation, the wells were developed to ensure proper hydraulic connection between
the well and surrounding geologic conditions. Development activities were terminated once the
water produced was essentially clear and free of suspended sediment or until conditions remain
unchanged.
4.3 BASELINE AND POST PILOT STUDYGROUNDWATER ANALYSIS
Groundwater sampling events were conducted in June 2010, August 2010, and May 2011 to
obtain baseline information on particular constituents in order to make accurate comparisons
upon completion of the biosparge and injection pilot studies. Baseline VOC analysis for
biosparge pilot study occurred in June 2010 for monitoring wells MW-19, 36, 38, 39, 41, 49, and
50 in Area 3. Monitoring wells in Area 2 were sampled for baseline biosparge VOC analysis as
part of the June 2010 Semi-annual Groundwater Sampling event and newly installed monitoring
wells MW-65, 66, 67, and 68 were sampled in August 2010. Groundwater samples were
collected in June 2010 from monitoring wells MW-05, MW-21, MW-26, UW-06, and UW-08.
Monitoring well MW-69 was installed for an additional down gradient monitoring point for
injection analysis in discussion with NCDENR Division of Water Quality for the Underground
Injection Control (UIC) permit. Installed on May 23, 2011, MW-69 was sampled to obtain
baseline data on May 24, 2011. Since completion of the Biosparge and Sulfate Injection Pilot
Studies, several groundwater sampling events have been performed to analyze the effectiveness
of the remedial alternatives. Pilot study sampling events were conducted on January 17, June 8,
June 23, and July 21, 2011. Pilot study sampling will continue per the monitoring schedule
included in the UIC Permit Application (UIC Permit NO. WI0300148).
4.4 PILOT STUDY IMPLEMENTATION
4.4.1 Biosparge
Following the installation of air sparge and monitoring wells, biosparge pilot study was
performed from October 25, 2010 to January 17, 2011. The sparge pilot test was conducted in
two different areas of the site, shown in Figure 3; Area 2 and Area 3. One air sparge (AS) well is
located in Area 2 (AS-06) and two AS wells are located in Area 3 (AS-04 and AS-05). An
attempt to install an additional sparge well and monitoring wells in an area designated as
"Area 1" was unsuccessful due to shallow auger refusal in several attempts to install wells.
Biosparge testing consisted of a "short" term pilot study of less than one week in Areas 2 and 3.
Air was delivered via tubing to air sparge wells at an average air flow rate of three standard cubic
feet per minute (scfm) with and average 25 pounds per square inch (psi) recorded at the AS well
head for Area 2. The average air flow rate and pressure recorded at the AS well head for Area 3
was 2.4 scfm and 15 psi, respectively. Depth to water (DTW), dissolved oxygen (DO), volatile
organic compounds (VOCs), carbon dioxide (CO2) and methane were recorded using field
instruments hourly, then daily in select wells surrounding the air sparge wells. Secondary wells

SECTIONFOUR Pilot Study
located at a further distance from the air sparge wells were measured at a less frequent basis.
Field measurements of the short term tests are included in Tables 2A and 2B. Testing started
October 25, 2010 and ended on October 29, 2010 in Area 2. Testing in Area 3, which is located
in the vicinity of the ISOC system, began on November 2, 2010 through November 5, 2010.
The long-term biosparge pilot study operated from November 9, 2010 through January 17, 2011
to monitor the effects of biosparging in relation to analytical testing. Table 3 shows the
analytical results before and after biosparge pilot testing. The ISOC system was turned off in
April 2010 to allow the area to acclimate to surrounding conditions for the pilot test and June
semi-annual sampling event for baseline analysis. Following the biosparge pilot study and ISOC
system repairs, operation of the ISOC resumed on March 1, 2011.
4.4.2 Biosparge Results
Area 2 Short Term Pilot Test (AS-06)
• Field VOC concentrations increase in closest monitoring wells MW-66 and MW-67
• CO2 concentrations decreased in closest wells MW-66, MW-67 and UW-08
• DO measurements were highest on the initial day of the pilot study then leveling off
and remaining fairly constant at lower results for the remainder of the test (MW-66,
MW-67, UW-04, and UW-08)
Area 3 Short and Long Term Pilot Tests (AS-05 and AS-05)
• Field VOC concentrations increase in the eight wells surrounding the sparge area
• CO2 increased in several wells. CO2 readings increased in concentrations as the pilot
study carried into the long term test. Air flow remained constant between short and
long term tests.
• DO measurements were highest during the initial days of the pilot test.
• Methane analysis increased in several wells as the test continued in the second and
third weeks.
Analytical Findings (Area 3 Long Term Plot Test)
• MTBE concentrations increased in MW-19 post pilot study. MW-19 is an ISOC well
and may show effects from ISOC influence when operating.
• MW-36 had increased analytical results after the pilot study for all analytes,
especially ethylbenzene and naphthalene.
As described above, URS collected field parameters from select Site monitoring wells as part of
the short and long term biosparge test.
Natural attenuation is microbially driven through oxygen reducing reactions. To evaluate the
success of natural attenuation in the subsurface, three components are typically evaluated:
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.2 Final Deliverables\Pilot Study\2010-2011 Pilot Study Summary.docx 4-3

SECTIONFOUR Pilot Study
• The presence of organic carbon as a microbial food source (hydrocarbons in this
case);
• Electron acceptors to provide energy transfer pathways; and
• The presence of metabolic end products, which illustrates degradation.
Dissolved Oxygen
DO is an important parameter to monitor because biodegradation of hydrocarbons occurs most
rapidly under aerobic conditions. In general, DO concentrations of approximately 2 mg/L or
greater indicate the presence of sufficient oxygen to support aerobic biodegradation, and levels
below 2 mg/L would be considered facultative and/or anaerobic.
As shown on Tables 2A and 2B, DO is present across the Site, and ranges from 0.55 to 6.63
mg/L. DO concentrations are generally lower in the impacted wells, and greater in the upgradient
and sidegradient wells. These data suggest that oxygen is being consumed for biodegradation in
the subsurface under aerobic conditions.
Methane
Methanogenesis is the process of degrading hydrocarbons with the end product being methane
gas (CH4) and carbon dioxide (CO2). The presence of methane suggests that methanogenesis has
occurred (or is occurring) in the impacted area of the Site. As shown on Tables 2A and 2B,
methane analysis increased in several wells, particularly during the Long Term testing in Area 3.
4.4.3 Sulfate Injection
Injection work began on May 16, 2011 and continued through May 23, 2011. The sulfate
injection pilot study consisted of the application of an Epsom salt and sodium bromide solution
to the subsurface utilizing an injection system delivered by GeoprobeTM. Each batch of sulfate
solution consisted of 757 grams of Epsom salt and 378.5 grams of sodium bromide, mixed into
solution in 100 gallons of potable water. GeoprobeTM rods, fitted with an injection tip that opens
at 100 psi, were advanced to a select depth where the solution was pumped to subsurface via the
hollow stemmed rods plumbed and fitted to gasoline powered diaphragm pumps which were
pressured to approximately 100 psi to activate the injection tool. Some injections occurred
simultaneously at two locations, e.g.) Al-I3 and Al-I5. Care was taken during simultaneous
injecting to select locations that were at as great of distances apart as possible to prevent
communication between the two active soil borings. The sulfate solution was injected at each
depth interval until the prescribed amount was injected or until friction loss to the ground surface
was realized. Injections were completed in two separate locations, referred to as Area 1 and
Area 2, shown in Figure 4. Area 1, centered around monitoring well MW-65, received injections
at 10 soil boring locations spaced evenly within a 20 ft. by 20 ft. area and labeled Al-I1 (Area 1-
Injection 1) through Al-I10. Similarly, a 20 ft. by 20 ft. area identified as Area 2 was established
P:\BP\Projects\Terminals\4762\5.0 Deliverables\5.2 Final Deliverables\Pilot Study12010-2011 Pilot Study Summary.docx 4-4

SECTIONFOUR Pilot Study
around monitoring well MW-68 and injected with the sulfate solution at 10 locations labeled
A2-I1 through A2-I10. Injection details are presented for Area 1 and Area 2 in Tables 4a and
4b, respectively. Based on the UIC permit application dated June 11, 2010 and presented in
Appendix C of this report, each injection point had the potential to receive a maximum of 400
gallons of the sulfate solution or 4,000 gallons total per area. Area 1 received a total of 1,640
gallons of the sulfate solution, while total injections for Area 2 totaled 2,700 gallons. Injection
intervals ranged from 10 ft. below ground surface (bgs) to 24 ft. bgs. Soil borings were
terminated at refusal in very tight soils. Having loose soils from 0 — 6.5 ft. bgs, due to the
required 6.5 ft. client hand dig requirement at each boring location, injections did not begin until
10 ft. bgs. Refer to Tables 4A and 4B for specific injection details.
After the injection event groundwater samples were collected from select wells in Areas 1 and 2
for laboratory analysis of VOC analytes along with MNA parameters. Sampling events of
selected wells were conducted on June 8, June 23, and July 21, 2011. VOC analysis and MNA
analysis results are presented on Tables 5 and 6, respectively. Laboratory Reports are included in
Appendix A.
4.4.4 Sulfate Injection Results
• Area 1 increased in BTEX and Naphthalene; however concentrations were also seen
historically at these levels.
• Area 2 increased in several wells for BTEX but no discernible trend is seen.
• No discernible trend is observed for DO, pH or specific conductance.
• Bromide, the injection tracer, was only detected in the area of injection (wells MW-61 in
Area 1 and MW-68 in Area 2). Bromide was not detected outside the injection area.
Field groundwater parameter measurements that were recorded subsequent to sampling the
monitoring wells are presented in Table 6. The pH, specific conductance, temperature, DO
ranges for the monitoring wells were as follows:
• pH ranged from 4.41 to 8.95 standard units (SU),
• Specific conductance ranged from 0.039 to 0.900 millisiemens per centimeter
(mS/cm),
• Temperature ranged from 15.53 to 28.31 degrees Celsius (°C),
• DO ranged from 0.13 to 8.69 milligrams per liter (mg/L),
Nitrate and sulfate serve as electron acceptors in the degradation process. Nitrate is reduced to
nitrite, and sulfate to sulfide, while the hydrocarbons are oxidized to carbon dioxide, methane,
and water. Typically, these degradation processes will occur in sequence with nitrate used first,
then iron is used until only sulfate is available, then sulfate reduction takes over. This would then
be followed by methanogenesis.
P:\BP\Projects\Terminals14762\5.0 Deliverables\5.2 Final Deliverables\Pilot Study\2010-2011 Pilot Study Summary.docx 4-5

SECTIONFOUR Pilot Study
Nitrate was not detected during this sampling event. Low nitrate levels could indicate that
degradation processes have depleted the nitrate or there is little available nitrate. Ferrous iron
was detected at variable concentrations, indicating that iron reduction may have occurred at the
Site. Sulfate concentrations across the Site indicate that very little sulfate is present in the area of
greatest impacts, but historical data indicate that there is sulfate available downgradient of the
impacted area. This may indicate that sulfate reduction has already occurred in the impacted
area.
Methane is generated as a byproduct of anaerobic hydrocarbon biodegradation. Nitrates presence
would be used for biodegradation before methanogenesis could occur. An increase in dissolved
methane concentrations, as groundwater travels downgradient, would be indicative of natural
biodegradation occurring.
Methane is present in groundwater across the Site. Methane concentrations are greatest in the
center and downgradient of the impacted area. Methane concentrations were low or not detected
in sidegradient wells. This indicates that methanogenesis has occurred at the Site.
DO concentrations across the Site show limited potential for aerobic degradation. Nitrate is not
available for the degradation process. Low sulfate concentrations in the impacted area suggest
that sulfate may have been reduced in the impacted area. The presence of methane suggests that
methanogenesis has occurred (or is occurring) in the impacted area of the Site.

SECTIONFIVE Conclusions and Recommendations
5.1 CONCLUSIONS
• VOC analysis for the biosparge testing showed an increase in concentrations from the
baseline sampling to sampling conducted in December 2010 and January 2011.
Increased concentrations in Area 3 were likely caused by shutdown of the ISOC
system during pilot study biosparge activities.
• Analytical results showed that VOCs in monitoring wells MW-65, MW-21, and MW-
26, wells in the immediate areas of the sulfate injections, have decreased while
inorganic concentrations have generally increased or remained relatively unchanged
from baseline results through July 21, 2011 results. Monitoring well MW-68, which
is within the boundary of the Area 2 injection, showed an increase in VOCs.
• Analytical results from June 8, 2011 sampling showed the greatest difference from
the baseline sample results. Subsequent sampling events show results moving closer
to baseline reporting.
• Bromide was reported in monitoring wells MW-65 and MW-68 during sampling
conducted following injection events. All baseline samples and pilot study samples
were non -detect for bromide in all sampled wells except pilot study samples of MW-
65 and MW-68, which are located within the injection areas. Correlating
concentrations of sulfate were also detected in monitoring wells MW-65 and MW-68
following injection events. Initial sulfate concentrations were lower than expected
following the injection events in both Areas 1 and 2. The sulfate concentrations also
appeared to decrease steadily over the post -injection sampling events in correlation
with the decreasing bromide concentrations indicating that physical processes present
in the aquifer are more dominant than biological processes and calls into question the
efficacy of the sulfate injection technology.
• The long term biosparge test appeared to indicate that VOC concentration reduction is
possible over time, however further sampling and we believe more data analysis
would be necessary to validate this trend.
5.2 RECOMMENDATIONS
URS will continue with Pilot Study sampling per the monitoring schedule submitted as part of
the Pilot Plan. Recommendations will be provided following review of data at the conclusion of
Pilot Study sampling activities. Upon review of all analytical data URS will make
recommendations for future remedial activities as part of the December semi-annual
groundwater sampling event, in accordance with the NCDENR-approved August 2005 Site
Groundwater Monitoring Plan.

Analytical test results meet all requirements of NELAC unless otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological
analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the
test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact
us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our
staff. This report shall not be reproduced except in full, without the written approval of the laboratory.

J estimated value — The result is >_ the Method Detection Limit (MDL) and < the Limit of Quantitation (LOQ).
ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/I), because one liter of water has a
weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas.
ppb parts per billion
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture. All other results are reported
on an as -received basis.

Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological
analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the
test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact
us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our
staff. This report shall not be reproduced except in full, without the written approval of the laboratory.

Analytical work is to be conducted in accordance with:
• Technical Requirements For Environmental Laboratory Analytical Services BP Laboratory Management Program (LaMP), Atlantic Richfield
Company- a BP- affiliated company, Revision 09 — FINAL Issued: 07/30/2007
• UST Section Guidelines For The Investigation And Remediation Of Contamination From Non -UST Petroleum Releases„ NC DENR, UST Section,
current version , which is available at http://www.wastenotnc.org/ust/docs/Non-USTGuid053107.pdf
Sample results are to be analyzed at the lowest dilution possible without harm to the instrument, and then at the proper dilution to ensure that
regulatory levels are achieved. Results are to be reported to the Method Detection Limit. Sample concentrations that are less than the PQL, but
greater than the MDL are to be J-flagged.
A trip blank will be included in the each shipment of VOA samples submitted to the laboratory.
It is anticipated that samples will be collected the week of May 16, June 16 and 22, July 20, August 17, and November 16, 2011, and February 15, 2012
2 Detection limits shall be less than the PQL or NC Groundwater Protection Standard (2L), whichever is lower.

< less than - The number following the sign is the limit of auantitation, the smallest amount of analyte which can be
reliably determined using this specific test.
> greater than
J estimated value — The result is >_ the Method Detection Limit (MDL) and < the Limit of Quantitation (LOQ).
ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/I), because one liter of water has a
weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas.
ppb parts per billion
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture. All other results are reported
on an as -received basis.
