B EXECUTIVE SUMMARY
The following Comprehensive Site Assessment Addendum (CSAA) – Soil and Groundwater has
been prepared by EMS Environmental, Inc. (EMS) for the Wendover Avenue Family Fare BP
#444 (Boulevard BP) located at 4839 West Wendover Avenue, Jamestown, Guilford County,
North Carolina. The location of the facility is shown on Figure 1. Figure 2 is a generalized site
plan of the current site layout. Sample locations are illustrated on the Soil Boring and Monitor Well
Location Map included as Figure 3.
This CSAA has been prepared to address petroleum hydrocarbon compounds that were released
from the underground storage tank (UST) system located on the site. The release was assigned
incident number 45216 by the North Carolina Department of Environmental Quality (NCEDQ),
UST Section.
Investigation for a potential release from the existing underground storage tank (UST) system was
initiated following a compliance inspection performed by the North Carolina Department of
Environmental Quality (NCDEQ) on November 14, 2018. Details of the inspection performed by the
NCDEQ on November 14, 2018 resulted in the reporting of four violations as described in the
November 20, 2018 NCDEQ Notice of Violation (NOV) correspondence (Appendix A). A Site
Check was performed to investigate for a suspected release in and around the regular gasoline
UST’s spill bucket which failed a hydrostatic test performed on the date of inspection. Repairs to the
regular gasoline spill bucket were performed by Jones and Frank, Inc. (J&F) and the documentation
was forwarded under separate cover to the NCDEQ.
EMS personnel mobilized to the site on March 5, 2019 to perform soil sampling adjacent to the
regular gasoline UST spill bucket. Two soil borings were attempted. However, no soil samples
were able to be collected as no soil recovery was achieved due to pea gravel materials
encountered in the boreholes. Since soil samples could not be obtained from the UST basin
proper, EMS contacted the Guilford County Department of Health and Human Services (DHHS)
and the NCDEQ Winston-Salem Regional Office (WSRO) for guidance on additional sampling to
satisfy the Site Check requirements. EMS was directed by the Guilford County DHHS and the
NCDEQ-WSRO to install a groundwater monitoring well down gradient and adjacent to the UST
basin and to collect a groundwater sample for volatile organic compounds.
Prior to installation of the monitoring well, EMS prepared and submitted a monitoring well
installation permit to the Guilford County DHHS. The permit #003-19-MW1-RW0 (Appendix B)
was received on March 29, 2019. Subsequently, EMS contracted Ransier Environmental Drilling,
Inc. (REDI) to supply a truck mounted drill rig to install the monitoring well. The well, identified as
MW-1, was installed on April 15, 2019 and is located as shown on Figure 3. Analysis by EPA
Method 6200B resulted in estimated or detectable concentrations of dissolved phase benzene in
excess of the Title 15A North Carolina Administrative Code (NCAC) Subchapter 2L Groundwater
Quality Standards (NC 2L GWQSs). Based on the exceedance, a UST-61 24-Hour Release and
UST Leak Reporting form was prepared and submitted to the NCDEQ on May 2, 2019 (Appendix
A).
Correspondence dated May 28, 2019 from the NCDEQ – WSRO indicated that the information
submitted for the release had been reviewed (Appendix A). Based on the information presented,
the NCDEQ requested the performance of a Limited Site Assessment (LSA).

iii

The LSA included the further assessment of impacted groundwater and a potential receptor survey.
LSA monitoring well installation activities were initiated on September 19, 2019, following receipt
of a revised monitoring well installation permit #003-19-MW4-RW0 (Appendix B) from the Guilford
County DHHS, As part of the assessment, three additional monitoring wells, MW-2 through MW-4
were installed upgradient and downgradient of the UST basin. Sampling and monitoring of the
groundwater in the monitoring wells identified the presence of petroleum compounds with
concentrations above the NCAC 2L groundwater standard. In addition, the potential receptor survey
revealed the presence of two water supply wells used for drinking water within 1,000 feet of the
source area. Three additional water supply wells are located within 1,500 feet of the source area
(Figure 4). Following review of the LSA, the Guilford County DHHS and NCDEQ classified the site
as High Risk with a 135D rank.
The NCDEQ issued M.M. Fowler a NORR dated December 3, 2019 that required the completion of
this Comprehensive Site Assessment (CSA) (Appendix A).
The CSA included the further assessment of impacted groundwater, soil quality sampling in the
vicinity of the UST basin, and slug testing to determine local hydrogeological characteristics. CSA
monitoring well installation and soil boring activities were initiated on February 26, 2020, following
receipt of a revised monitoring well installation permit #003-19-MW7-RW0 (Appendix B) from the
Guilford County DHHS, As part of the assessment, three additional monitoring wells, MW-5 through
MW-7 were installed upgradient and downgradient of the UST basin. Sampling and monitoring of the
groundwater in the monitoring wells confirmed the presence of petroleum compounds with
concentrations above the NCAC 2L groundwater standard. Soil quality sampling revealed multiple
compounds that were reported to be present at estimated or detectable concentrations in one or
more soil samples. Of the reported estimated or detected concentrations, none were reported
above the Soil to Groundwater MSCC.
Slug testing performed for the CSA and CSAA investigation was evaluated using the Bouwer-
Rice Method. The calculated average hydraulic conductivity was 7.80 x 10-4 cm/sec (2.21
feet/day) and the calculated average linear groundwater velocity of the shallow water table was
0.31 feet/day.
Following review of the CSA, the Guilford County DHHS and NCDEQ requested that additional
investigation be performed in correspondence dated April 13, 2020. The purpose of this CSAA is to
address the comments and directions in the correspondence (Appendix A).
B.1 Source Information
Type of Contaminant
 Gasoline (Regular UST gasoline spill bucket location).
Source of Release
Regular gasoline UST.
Amount of Release
Unknown.

iv

B.2 Initial Abatement/Emergency Response (ER) Information
No abatement or emergency response activities have occurred at the facility to date.
B.3 Hydrogeologic Investigation
 The calculated average hydraulic conductivity from slug test data is 7.80 x 10-4 cm/sec (2.21
feet/day).
 The calculated average linear groundwater velocity of the shallow site soils is 0.31 feet/day.
 Groundwater at the site was found to be flowing from southeast to northwest.
B.4 Soil and Groundwater Assessment
 Analysis of soil samples collected around the UST basin indicated no detectable concentrations
above the Soil to Groundwater Maximum Soil Contaminant Concentrations (MSCC).
 Analysis of groundwater samples collected from on site monitoring wells indicated impacted
groundwater is present with concentrations that exceed the NCAC 2L groundwater standards
but are below the NC Gross Contamination Limits (GCLs).
 The impacted groundwater is present in a plume that is located in the vicinity of the UST basin
and extends to the northwest and south on site.

B.5 Risk Classification
The site is currently ranked as High risk by the NCDEQ due to the presence of water supply wells
located within 1,000 feet of the source.
B.6 Current Soil and Groundwater Remediation Standards
 Soil: Residential MSCC.
 Groundwater: NC 2L GWQSs.
B.7 Recommendations
 The site is High risk due to the presence of nearby residential water supply wells. The nearest
downgradient receptor, identified as WSW-1, currently has not been impacted based upon
laboratory analytical data. The site rank may be lowered based on groundwater modeling of
potential future impacts and/or connection of the residence to the municipal water.
 No soil impact has been encountered with concentrations above the Soil to Groundwater MSCC.
Therefore, it appears the NCDEQ incident may be closed without a land-use restriction for soil.
 Additional groundwater assessment activity does not appear to be required to delineate
dissolved phase petroleum hydrocarbons downgradient of the UST basin.
 Additional groundwater assessment activity may be required south of the UST basin area since
additional assessment for the CSAA did not result in complete horizontal delineation.
 Vertical groundwater delineation has been achieved through the installation of deep monitoring
well MW-8D.

D SITE HISTORY AND SOURCE CHARACTERIZATION
The Wendover Avenue Family Fare BP#444 (Facility ID 00-0-0000035427) is located at 4839
West Wendover Avenue, Jamestown, Guilford County, North Carolina 27282. The site vicinity and
location are shown on the attached portion of the Greensboro, NC 7.5 Minute Series topographical
map included as Figure 1. The site is characterized by three on-site structures consisting of a Family
Fare convenience store, detached carwash, and a detached canopy protecting retail petroleum
dispensing equipment. Site features are illustrated on the Site Plan Map included as Figure 2. Site
sample locations are illustrated on the Soil Boring and Monitor Well Location Map included as Figure
3.
This CSAA has been conducted per NCDEQ NORR correspondence dated April 13, 2020 and
performed under the NCDEQ Task Authorization (TA) preapproval TA #45216-02. A copy of the
NORR correspondence and preapprovals are attached in Appendix A.
D.1 UST Owner and Operator Information
Based on the review of UST ownership records, the UST owner/operator and responsible party
information is summarized in Table 1. The USTs are located in the UST basin as shown on Figure
2 and are all owned by M.M. Fowler, Inc.
D.2 UST System Information
Petroleum fuels at the station are dispensed from two underground storage tanks (USTs) of single
wall fiberglass reinforced plastic (FRP) construction. The USTs are used for petroleum retail
purposes and were reportedly installed on January 31, 1997. According to the NCDEQ registered
tank database the UST system consists of one 10,000-gallon regular gasoline UST and one 15,000-
gallon compartment UST containing plus and premium gasoline. The UST system information is
summarized in Table 2.
D.3 Previous Site Assessment Activity
Site assessment activity has been performed as part of a Site Check, a Limited Site Assessment
(LSA), and a Comprehensive Site Assessment (CSA) – Soil and Groundwater.
D.3.1 Site Check (2019)
A Site Check was initiated following a compliance inspection performed by the NCDEQ on November
14, 2018. The inspection resulted in the reporting of four violations as described in the November
20, 2018 NCDEQ NOV correspondence (Appendix A). The Site Check was performed to
investigate a potential release in and around the regular gasoline UST’s spill bucket which failed a
hydrostatic test performed on the date of inspection. Repairs to the regular gasoline spill bucket were
performed by Jones and Frank, Inc. (J&F) and the documentation was forwarded under separate
cover to the NCDEQ.

EMS personnel mobilized to the site on March 5, 2019 to perform soil sampling adjacent to the
regular gasoline UST spill bucket. Two soil borings were attempted. However, no soil samples
were able to be collected due to the presence of pea gravel materials encountered in the
boreholes. Since soil samples could not be obtained from the UST basin proper, EMS contacted
the Guilford County DHHS and the NCDEQ - WSRO for guidance on additional sampling to satisfy
the Site Check requirements. EMS was directed by the Guilford County DHHS and the NCDEQ-
WSRO to install a groundwater monitoring well down gradient and adjacent to the UST basin and
to collect a groundwater sample for volatile organic compounds (VOCs).
Prior to installation of the monitoring well, EMS prepared and submitted a monitoring well
installation permit to the Guilford County DHHS. The permit #003-19-MW1-RW0 (Appendix B)
was received on March 29, 2019. Subsequently, EMS contracted REDI to supply a truck mounted
drill rig to install the monitoring well. The well, identified as MW-1, was installed on April 15, 2019
and is located as shown on Figure 3. Analysis by EPA Method 6200B (Table 3) resulted in
estimated or detectable concentrations of dissolved phase benzene in excess of the NC 2L
GWQSs. Based on the exceedance, a UST-61 24-Hour Release and UST Leak Reporting form
was prepared and submitted to the NCDEQ on May 2, 2019 (Appendix A).
The results of the site check were documented in a report entitled Site Check Report Wendover
Avenue Family Fare #444 and dated May 6, 2019 that was submitted to the Guilford County
DHHS and the NCDEQ.
D.3.2 Limited Site Assessment (2019)
Following the review of the Site Check Report, the NCDEQ issued M.M. Fowler a NORR. The
NORR dated May 28, 2019 (Appendix A) indicated that the information submitted for the release
had been reviewed and that a LSA was required to be performed on the site.
A potential receptor survey was performed on July 9, 2019 in support of the LSA investigative
activities. A door to door search of all residences and business establishments within 1,500 feet
of the site was performed in support of the receptor survey.
Five potable water supply wells were identified within 1,500 feet of the site. The water supply well
locations are depicted on Figure 4. Two of the wells, identified as WSW-1 and WSW-2, are
located within 1,000 feet of the source area. No other water supply wells for any purpose were
located within 1,500 feet of the release source.
Adjacent property ownership, contact information, and zoning were researched through the
Guilford County iMaps website. Adjacent property information has been updated to reflect current
property owner status as of September 2019. The summary of adjacent property information and
potential receptor information is tabulated in Table 4 and shown in Figure 4.
The nearest surface water body has been identified at approximately 600 feet south of the site
UST basin (Figure 1). The surface water body has been identified as an unnamed tributary (UT)
to Uwharrie Lake which ultimately empties into Long Branch Creek. Long Branch Creek (Stream
Index 17-2-1-(1) is designated as a Water Supply (WS) - IV surface water classification.

The LSA included the evaluation of the groundwater quality upgradient and downgradient of the UST
basin. Following receipt of an updated permit #003-19-MW4-RW0 (Appendix B) monitoring well
installation activities were initiated on September 19, 2019. EMS contracted REDI to install three
Type-II 2-inch diameter PVC monitoring wells identified as MW-2 to MW-4. The Type-II wells were
advanced by air rotary stem auger methods to 25 feet BGS. Well construction permits and
construction records (GW-1 forms) are included in Appendix B.
Groundwater samples were collected from wells MW-1 through MW-4 on September 25, 2019.
The MW-1 sample was analyzed by EPA Method 6200B. The samples from MW-2 through MW-
4 were analyzed by EPA Method 6200B, total lead by EPA Method 6010, EPA Method 504.1 for
low detection EDB, and MADEP VPH consistent with a gasoline only release.
Laboratory analytical results revealed that dissolved phase petroleum hydrocarbons were present
in excess of the 10 x NCAC 2L GWSs in source monitoring well, MW-1 and in MW-2 for multiple
compounds. Of the compounds detected, none were present at a concentration in excess of the
GCL standards.
The findings of the LSA were documented in a report titled Limited Site Assessment - Phase I
and II that was dated October 11, 2019. The report was submitted to the Guilford County DHHS
and the NCDEQ.
D.3.3 Comprehensive Site Assessment (CSA) – Soil and Groundwater (2020)
Following the review of the LSA Report, the NCDEQ and Guilford County DHHS issued M.M.
Fowler a NORR. The NORR dated, December 3, 2019, required the completion of a CSA – Soil
and Groundwater report.
The CSA included additional evaluation of the groundwater quality upgradient and downgradient of
the UST basin. Following receipt of an updated permit #003-19-MW7-RW0 (Appendix B) monitoring
well installation activities were initiated on February 26, 2020. EMS contracted REDI to install
three Type-II 2-inch diameter PVC monitoring wells identified as MW-5 to MW-7. The Type-II wells
were advanced by air rotary methods to approximately 25 feet BGS. Well construction permits
and construction records (GW-1 forms) are included in Appendix B.
In addition, four soil borings, identified as SB-1 through SB-4, were advanced during the CSA
investigation for the purpose of assessing potential subsurface petroleum compounds around the
UST basin. The resulting soil quality sampling indicated that residual petroleum hydrocarbons
were either non detectable or at concentrations below the Soil to Groundwater MSCC. Therefore,
no further assessment or remediation of the soils appears necessary for this site.
Groundwater samples were collected on March 2, 2020 from wells MW-1 through MW-7. The
samples were analyzed by EPA Method 6200B. The samples from MW-5 through MW-7 were
also analyzed by EPA Method 6200B, total lead by EPA Method 6010, EPA Method 504.1 for low
detection EDB, and MADEP VPH consistent with a gasoline only release.

Laboratory analytical results revealed the presence of multiple target VOCs that were detected
with concentrations that exceeded the NCAC 2L GWQS but were below the NC GCLs. The
compounds include Benzene, Toluene, Ethylbenzene, Total Xylenes, MTBE, Isopropylbenzene,
Naphthalene, n-Propylbenzene, 1, 2, 4-Trimethylbenzene, and 1, 3, 5-Trimethylbenzene. VOC
groundwater analytical results are summarized on Table 3. No target oxygenates were reported
to be present above the NC 2L GWQS. The compound EDB was not reported to be present in
any groundwater sample.
In addition, the two water supply wells located within 1,000 feet of the source area were accessed
in an attempt to collect water samples on March 2, 2020. One sample was collected from an
exterior spigot at WSW-1 located at 4818 West Wendover Avenue. No sample could be obtained
at WSW-2, located at 5955 Hickory Grove Road since the residence was unoccupied and there
was no power to the residence or well pump. No target compounds were reported to be present
in the water supply well sample collected from WSW-1.
Following review of the CSA, the Guilford County DHHS and NCDEQ requested that additional
investigation be performed in correspondence dated April 13, 2020. The purpose of this CSAA is to
address the comments and directions in the correspondence.

G CSA SOIL SAMPLING INVESTGATION AND RESULTS
Four soil borings, identified as SB-1 through SB-4, were advanced during the CSA investigation
for the purpose of assessing site subsurface petroleum compounds around the UST basin. The
resulting soil quality indicated that residual petroleum hydrocarbons exist in the subsurface below
the Soil to Groundwater MSCC. No further assessment or remediation of the soils appears
necessary for this site and none were performed during the CSAA site activities.
G.1 Soil Sample Information
Soil Lithology
According to the Geologic Map of North Carolina (Brown et al, 1985), the site is located within the
Carolina Slate Belt of the Piedmont Physiographic Province. Subsurface geology in the site
vicinity has been mapped as CZg and is described as metamorphic granitic rock, late Proterozoic
to late Cambrian aged. The unit is further described as megacrystic, well foliated; locally contains
hornblende.
During the installation of SB-1 through SB-4 and MW-1 through MW-9, a dark grey to reddish
orange sandy clay was generally encountered to a depth of 13 to 15 feet BGS. Semi-competent
to competent bedrock was encountered to the boring terminus.
Type of samples (from excavation, stockpiled soil, etc.)
Four soil borings were advanced by REDI on February 26, 2019 during the CSA assessment. Soil
boring locations are shown on Figure 3. The borings were advanced around the periphery of the
UST basin to a total depth of 10 feet using direct push technology.
Sample collection procedures (grab, split spoon, hand auger, etc.)
Soil samples were collected continuously in five feet long plastic tubes from the ground surface
to the termination depth of 10.0 feet. Each soil sample was inspected, split into resealable plastic
baggies, and then field screened within the resealable plastic baggie for volatile organic
compounds (VOCs) with the use of a MiniRAE 2000 Photo Ionization Detector (PID) calibrated in
accordance with manufacturer instruction prior to use.
The 8-10 foot soil samples were collected using new disposable powder free nitrile gloves, placed
within laboratory supplied containers and then into iced coolers for transportation to the
laboratory. The soil samples were submitted to a North Carolina certified laboratory for analysis
of volatile organic compounds (VOCs) by EPA Method 8260. All samples were submitted on the
date of collection to ENCO Laboratories, Inc. located in Cary, North Carolina.
Location of soil samples
The soil boring locations are shown on Figure 3.
Depth of soil samples
Soil samples were collected from the 8 to 10 foot depth interval.

results are summarized on Table 5 and the sample locations have been depicted on Figure 3
G.2 Quality-control measures
Sample handling procedures including sample preservation techniques and sample
transport procedures.
The laboratory provided coolers, sample containers (pre-acidified if required), labels and
TerraCoreTM sample collection devices. The samples were handled using disposable gloves.
Volatile soil samples were collected with disposable sampling devices which measure the
appropriate sample volume. The volatile samples were placed in sample bottles preserved with
sodium bisulfate or methanol. The soil samples were placed in coolers that were chilled with ice
and relinquished to the laboratories.
Decontamination procedures
Samples were collected using new clean macro-core plastic sleeves.
Samples collected for quality control purposes (e.g., duplicates, field blanks, trip blanks,
etc.).
No quality control samples were submitted to the laboratory.
G.3 Soil Assessment Results
PID monitoring detected VOC concentrations in multiple soil samples. VOC concentration
measurements ranged from 0.0 parts per million (ppm) for SB-4 to 46.8 ppm for SB-2
The results of soil sampling are tabulated on Table 5. Multiple compounds were reported to be
present at estimated or detectable concentrations in one or more soil samples. Of the reported
estimated or detected concentrations, none were reported above the Soil to Groundwater MSCC.
Laboratory report forms are included in Appendix C.

H CSA AND CSAA GROUNDWATER INVESTIGATION AND SAMPLING RESULTS
One shallow monitoring well, MW-1, was installed as part of the Site Check assessment. Three
shallow monitoring wells (MW-2, MW-3, and MW-4) were installed on-site for the LSA assessment
to estimate the horizontal extent of dissolved phase hydrocarbon constituents.
Three additional monitoring wells, identified as MW-5, MW-6, and MW-7, were installed as part
of the CSA investigation for the purpose of further defining the dissolved phase hydrocarbon
plume. Following receipt of an updated permit #003-19-MW7-RW0 (Appendix B), the monitoring
wells MW-5 to MW-7 were installed on February 26, 2020 in the locations shown on Figure 3.
Vertical delineation was not required for the CSA investigation as directed by the Guilford County
DHHS and NCDEQ.
Two additional monitoring wells, identified as MW-8D and MW-9 were installed as part of the
CSAA investigation for the purpose of further defining the dissolved phase hydrocarbon plume
both horizontally and vertically. Following receipt of an updated permit #003-19-MW9-RW0
(Appendix B), the monitoring wells were installed on June 2 – 4, 2020 in the locations shown on
Figure 3. Vertical delineation was required for the CSAA investigation as directed by the Guilford
County DHHS and NCDEQ.
Type II monitoring well, MW-9, was installed using air rotary techniques and was constructed with
20 feet of 2-inch inner diameter (I.D.) slotted PVC screen and five feet of schedule 40 PVC riser
pipe. Coarse grained filter sand was added to the borehole from the boring terminus to a depth
above the screened interval. A bentonite pellet seal was emplaced above the filter sand and the
remainder of the borehole was filled with a cement grout and finished with a bolt down manhole
and cover. Well installation details are summarized on Table 6 and are included with the
monitoring well installation schematics and NCDEQ Well Completion Records in Appendix B.
Type-III vertical delineation well, MW-8D, was nested beside shallow depth well MW-1 and was
completed utilizing air rotary drilling methods to a final depth of 45 feet BGS. Well construction
consisted of a 5-inch diameter PVC outer casing drilled to 30 feet BGS. An inner casing of 2-inch
diameter was then drilled and set from 0 to 40 feet BGS and a 0.01-inch slotted PVC well screen
was set from 40 to 45 feet BGS. The well was completed with sand from 38 to 45 feet BGS, a 2
foot bentonite seal from 36 to 38 feet BGS, and neat cement from -0.25 to 36 feet BGS. Well
installation details are summarized on Table 6 and are included with the monitoring well
installation schematics and NCDEQ Well Completion Records in Appendix B.
H.1 Groundwater Sampling Information
Location of Water Samples
Groundwater samples were collected for the CSA from monitoring wells MW-1 through MW-7 on
March 2, 2020. Groundwater samples were collected for the CSAA from monitoring wells MW-8D
and MW-9 on June 8, 2020. The results are tabulated on Table 3. The results from the March 2,
2020 and June 8, 2020 sample events have been combined to produce distribution maps
associated with this report.

10

In addition, the two water supply wells located within 1,000 feet of the source area were accessed
for the CSA investigation in an attempt to collect water samples on March 2, 2020. One sample
was collected from an exterior spigot at WSW-1 located at 4818 West Wendover Avenue. No
sample could be obtained at WSW-2, located at 5955 Hickory Grove Road since the residence
was unoccupied and there was no power to the residence or well pump.
Field Measurements
Depth to water (DTW) measurements were measured with an oil-water interface probe in MW-1
through MW-7 on March 2, 2020 and from MW-8D and MW-9 on June 8, 2020. DTW in the
shallow groundwater wells ranged from 8.62 feet below top of casing (BTOC) in MW-1 to 12.77
feet BTOC in MW-3. Vertical delineation well MW-8D DTW was measured at 9.34 feet BTOC.
The measurements are summarized on Table 6.
Sample collection procedures
The groundwater samples were collected at the monitoring wells with new, disposable bailers and
new nylon line. The samples were collected using clean disposable gloves and placed within
laboratory supplied containers.
The water supply well sample, WSW-1, was collected from an exterior spigot. The spigot was
allowed to run for approximately 15 minutes prior to the sample being collected using clean
disposable gloves and placed within laboratory supplied containers.
Time/date collected
The dates and sample collection times are listed on the chain of custody forms in Appendix C.
Sample identification

I HYDROGEOLOGIC INVESTIGATION

I.1 Groundwater Flow Direction
Top of casing (TOC) and ground surface (GS) elevations were measured on September 25, 2019
for MW-1 through MW-4, on March 2, 2020 for MW-5, MW-6, and MW-7, and on June 8, 2020 for
MW-8D and MW-9 using a tripod mounted level and survey rod. The elevations were measured
to the nearest 0.01 foot to the concrete pad on MW-1 with a referenced elevation of 860.00 feet
above mean sea level (amsl). The measurements are included in Table 6.
Fluid level measurements were collected from the monitoring wells MW-1 to MW-7 on March 2,
2020 and from MW-8D and MW-9 on June 8, 2020 to the nearest one hundredth of a foot with an
oil-water interface probe. Data gathered on the measurement dates were used to calculate
relative water table elevations and the results are provided on Table 6.
Areas of equal water table elevations on March 2, 2020 were contoured to depict the apparent
local groundwater flow direction as shown on Figure 5. Groundwater flow is perpendicular to the
contour lines from areas of higher to lower water table elevations. Groundwater was found to be
flowing to the north-northwest.

I.2 Hydraulic Gradient
The shallow aquifer hydraulic gradient, from data collected on March 2, 2020, was measured
between MW-1 and MW-3. The calculated gradient was 0.045 feet/feet.

I.3 Hydraulic Conductivity
Slug tests were performed in three test wells, MW-1, MW-2 and MW-4, on March 2, 2020 and in
MW-6 on June 2, 2020. MW-1 and MW-2 are located in close proximity to the UST basin and MW-
4 and MW-6 are located outside of the UST basin area. The test in MW-6 on June 2, 2020 was
performed to verify the results of the March 2020 slug testing outside of the UST basin which appears
more representative of residual site soils. The tests were conducted by removing approximately two
liters of water from each well. The rising water levels were measured using an oil-water interface
probe at pre-set time intervals. The fluid levels were measured while the wells were allowed to
recharge within 95% of the pre-withdrawal DTW levels.
Hydraulic conductivity (K) is defined as the capacity of a porous medium to transmit water by the
fully saturated thickness of the water-bearing unit over time. Hydraulic conductivity is governed
by the size and shape of the pores, the effectiveness of the interconnection between pores and
the physical properties of the fluid (Driscoll, 1986). The dimensions of hydraulic conductivity
commonly used in data analysis are feet per day (ft/day). Values for hydraulic conductivity were
evaluated from the slug test data using the Bouwer & Rice Slug Test Method through the use of
the computer program Super SlugTM developed by Starpoint Software, Inc. (www.pointstar.com).

13

Based upon the slug test data from monitoring wells MW-1, MW-2, MW-4, and MW-6, graphical
solutions were compiled by Super SlugTM which calculated values of hydraulic conductivity (K) for
the unconfined aquifer. The values for hydraulic conductivity obtained from the test data were
8.04 feet/day (MW-1), 10.86 feet/day (MW-2), 1.94 feet/day (MW-4), and 2.48 feet/day (MW-6)
for the Bouwer-Rice Method (geometric means). The calculated K values for MW-1 and MW-2
adjacent to the UST basin area are much larger than the calculated K values outside of the UST
basin area (MW-4 and MW-6) and may be reflective of basin materials instead of residual soils.
As a result, the values from outside the basin area are considered to be representative of residual
site soils. The method assumes that the assumptions of the model are valid and that no known
preferential pathways are present in the shallow aquifer. The raw data and graphical solutions are
included in Appendix D.

I.4 Porosity and Groundwater Flow Velocity
The average linear groundwater velocity of the shallow water bearing deposits may be calculated
from a derivation of Darcy's Law for fluid flow through a porous medium. The groundwater velocity
equation is as follows:
Vs = K/ne * I
Where:
Vs = groundwater velocity (ft/day)
K = hydraulic conductivity (ft/day)
ne = effective porosity (dimensionless)
I = hydraulic gradient (ft/ft)
The effective porosity (ne) of the sediments was assumed to be 33% based upon porosity values
for clays published by Fetter (1994). Using the hydraulic gradient of 0.045 feet/foot between MW-
1 and MW-3 (3/02/20) and the average Bouwer-Rice Method calculated hydraulic conductivity of
7.80 x 10-4 cm/sec (2.21 feet/day) in MW-4 and MW-6 outside of the UST basin area, the
calculated average linear groundwater velocity of the shallow water table is 0.31 feet/day or
113.15 feet/year based upon the Bouwer-Rice K-value.

J REGIONAL SITE GEOLOGY AND HYDROGEOLOGY
According to the Geologic Map of North Carolina (Brown et al, 1985), the site is located within the
Carolina Slate Belt of the Piedmont Physiographic Province. Subsurface geology in the site
vicinity has been mapped as CZg and is described as metamorphic granitic rock, late Proterozoic
to late Cambrian aged. The unit is further described as megacrystic, well foliated; locally contains
hornblende.
Groundwater in the site vicinity is typically recharged by the percolation of rainfall into areas of
high or intermediate relief. Groundwater is then stored in pore spaces or relict fractures in the
upland sediments, saprolite, and in fractures in the parent rock. Groundwater then discharges by
gravity drainage to areas of low relief such as streams or lakes and discharge points such as
potable water wells.

15

K SITE GEOLOGY AND HYDROGEOLOGY
K.1 Site Geology
The general site geology has been characterized through observations made during the
advancement of soil borings and monitoring well installations. During the installation of SB-1
through SB-4 and MW-1 through MW-7, a dark grey to reddish orange sandy clay was generally
encountered from the near surface to a depth of 13 to 15 feet BGS. Semi-competent to competent
bedrock was encountered to the boring terminus. Figure 6 shows the location of generalized
geologic cross section transects across the site and Figure 7 depicts the generalized cross
sections of the site geology.
K.2 Site Hydrogeology
Groundwater occurs at depths ranging between 8 to 12 feet BTOC on the site and generally flows
towards the northwest. Based on the results of slug testing, shallow groundwater moves with a
relatively low to moderate flow velocity across the site.

L DISCUSSION

L.1 Nature and Extent of Contamination

L.1.1 Soil Quality
Soil quality evaluations on the periphery of the UST basin have resulted in the identification of
multiple reported compounds with estimated or detectable concentrations less than the Soil to
Groundwater MSCC.

L.1.2 Groundwater Quality
Multiple VOCs were detected in one or more monitoring wells with detectable or estimated
concentrations that exceed the NCAC 2L GWQS and were below the NCAC GCLs. The
compounds include Benzene, Toluene, Ethylbenzene, Total Xylenes, MTBE, Isopropylbenzene,
Naphthalene, n-Propylbenzene, 1,2,4-Trimethylbenzene, 1,3,5-Trimethylbenzene, Tert-Amyl
Alcohol (TAA), and Tert-Butyl Alcohol (TBA). VOC groundwater analytical results are summarized
on Table 3. The compounds Benzene, Toluene, Ethylbenzene, Xylenes (total), MTBE, and
Naphthalene were chosen to represent the aerial extent of the dissolved phase hydrocarbon
plume. The interpreted extent of the compounds on the site are shown on the attached Figures
8 through 13.
The source of Naphthalene, typically not associated with gasoline releases is unknown.
Naphthalene is more typically associated with diesel fuel or heating oil releases. The current
property owner does not dispense diesel fuel or heating oil. The site was previously owned by BP
Oil Company (BP) who purchased the property in July 1996. The tanks on site were installed in
1997. It is possible that BP had previously used one of the compartments of the USTs for the
purpose of the distribution and resale of diesel fuel prior to acquisition of the property by M.M.
Fowler, in April of 2002. A search of the NCDEQ Registered Tank Database, the NCDEQ UST
Facility Database, and the NCDEQ Incident Management Database did not reveal any additional
tanks or reported releases associated with this facility.

L.2 Maximum Contaminant Concentrations - Soil
The results of soil sampling are tabulated on Table 5. Multiple compounds were reported to be
present at estimated or detectable concentrations in one or more soil samples. Of the reported
estimated or detected concentrations none were reported above the Soil to Groundwater MSCC.

17

L.3 Maximum Contaminant Concentrations – Groundwater
The following dissolved phase compounds were detected at concentrations that exceeded the
NCAC 2L GWQS standards but were less than the GCLs during the March 2, 2020 and June 8,
2020 groundwater sampling event:
Compound Concentration Sample ID Gross Contaminant Level
Benzene 2,200 MW-1 5,000
Toluene 32,000 MW-5 260,000
Ethylbenzene 3,800 MW-1 84,500
Xylenes (total) 36,000 MW-5 85,500
MTBE 43 estimated MW-2 20,000
Isopropylbenzene 130 estimated MW-1 25,000
Naphthalene 310 MW-1 6,000
n-Propylbenzene 420 MW-1 30,000
1,2,4-Trimethylbenzene 2,900 MW-1 28,500
1,3,5-Trimethylbenzene 660 MW-1 25,000
Tert-Amyl Alcohol (TAA) 56 MW-9 40,000
Tert-Butyl Alcohol (TBA) 17 estimated MW-9 10,000

L.4 Contaminant Migration and Potentially Affected Receptors
The VOC plume appears to be migrating north-northwest from the UST basin and appears to be
primarily contained on site. Downgradient water supply wells do not appear to be impacted.
L.5 Site Specific Conditions or Actions that would Result in the Lowering the Risk
Classification or Site Priority Ranking
The site is ranked as High Risk due to the presence of water supply wells within 1,000 feet of the
source area. Connection of the properties served by the water supply wells to the municipal
system and/or contaminant fate and transport modeling from the impacted area to the receptors
may lower the risk to Low Risk and make the site eligible for closure

L.6 Applicable Cleanup Levels
 Soil: Lower of the Soil to Groundwater or Residential MSCC.
 Groundwater: NC 2L GWQS
Copies of the CSA public notifications are included in Appendix E.

18

M CONCLUSIONS AND RECOMMENDATIONS

The following conclusions were reached regarding the subject site:
 The site is ranked High risk due to the presence of water supply wells within 1,000 feet of the
source area.
 The site appears to have a single release area centered near the UST basin. Gasoline was
released at this location based upon the failure of the hydrostatic tests for the containment
buckets.
 Groundwater from the source area flows north-northwest. The nearest receptor is a potable water
supply well located 500 feet to the north at 4818 West Wendover Avenue, Jamestown, NC. The
well has not been adversely impacted as of March 2, 2020.
 Soil sampling results indicate that there are no detectable petroleum compound concentrations
that exceed the Soil to Groundwater MSCC.
 Groundwater sampling results indicate that dissolved phase petroleum compounds are present
on the site with concentrations that are above the NC 2L GWQS but below the GCLs.
 The presence of Naphthalene, typically not associated with gasoline only releases, is unknown.
The site was previously owned by BP Oil Company (BP) who purchased the property in July
1996. The tanks on site were reportedly installed in 1997. It is possible that one of the
compartments of the USTs was previously used for the purpose of the storage and resale of
diesel fuel prior to formal acquisition of the property by M.M. Fowler, in April of 2002.
 It may be possible to lower the site risk by contaminant fate and transport modeling and/or
connecting the potentially impacted properties to municipal water supplies.

Facility ID#: 00-0-0000035247

Dear Marvin L. Barnes Jr:

On November 14, 2017, I conducted a compliance inspection at the above-referenced facility. I observed that
underground storage tanks (USTs) at Wendover Family Fare 444 are not in compliance with North Carolina UST
regulations (North Carolina Administrative Code [NCAC] 2N "Criteria and Standards Applicable to Underground
Storage Tanks). According to those rules (15A NCAC 2N .0203) M. M. Fowler, Inc. is identified as the owner
and/or operator of UST(s) at Wendover Family Fare 444.

The following violations of the state rules (15A NCAC 2N) were observed on November 14, 2017 at Wendover
Family Fare 444. Following each violation are the actions required to correct the violations:

Violation 1: 15A NCAC 2N .0301 UPG2; Failure to meet the spill prevention requirements of a 'new tank system'
as required by federal regulation 40 CFR 280.20(c) (as incorporated by 15A NCAC 2N .0301).
Corrective Action(s):
All UST systems installed after December 22, 1988 are defined as 'new tank systems.' All "new tank systems" that
are filled by transfers of more than 25 gallons at one time are required to have spill prevention equipment. Please
complete the following actions:

1) Repair or empty your spill prevention equipment. If the spill prevention equipment is replaced as part of the
repair then the spill prevention equipment must meet the secondary containment requirements of 15A
NCAC 2N .0900 and must have an integrity test conducted after installation that is documented on a UST-
23A form, Triennial UST Spill Bucket Integrity Testing.
Submit a copy of invoices, designs or other documentation of the completed work within 30 days of receipt of this
NOV to the inspector at the address provided. In addition, if spill prevention is added, please submit a UST-8 form,
Notification for Activities Involving USTs, identifying methods (i.e., catchment basin) used along with a UST-23A
form, Triennial UST Spill Bucket Integrity Testing.
Comment: Tank #2R:

Violation 2: 15A NCAC 2N .0502 LD1; Failure to provide leak detection for a regulated tank in accordance with
federal regulation 40 CFR 280.41 (as incorporated by 15A NCAC 2N .0502, 15A NCAC 2N .0301, 15A NCAC
2N .0302 and/or 15A NCAC 2N .0304).
Corrective Action(s):
The Division of Waste Management UST Section has determined that leak detection has not been conducted on a

regulated tank.

1) Single-wall monitored UST: Please immediately conduct a tank tightness test (note: an Automatic Tank
Gauge can not be used to conduct the tank tightness test) on all applicable USTs and submit a copy of your
next month's tank leak detection records.
Please submit, within 30 days of receipt of this notice, a copy of the tank tightness test results (and if applicable,
interstitial space tightness test results) and submit, within 30 days of receipt of this notice, a copy of your leak
detection records (for your chosen leak detection method(s)) for the month following the date of receipt of this
notice to the inspector at the address provided.
Comment: Tank #1P: ,
Tank #2R:

Violation 3: 15A NCAC 2N .0502 LD12; Failure to provide leak detection for pressurized piping systems
associated with regulated tanks in accordance with federal regulation 40 CFR 280.41(b)(1)(ii) (as incorporated
by 15A NCAC 2N .0502).
Corrective Action(s):
Leak detection must be provided for pressurized piping systems. Please complete one of the following requirements:

1) Conduct a line tightness test for each piping system associated with the regulated tank(s). Line tightness
testing is required annually for pressurized piping systems. OR Conduct a line tightness test and apply an
acceptable method of monthly monitoring for each piping system associated with the regulated tank(s).
Within 30 days of receipt of this notice, please submit a copy of the line tightness test results to the inspector
at the address provided. If you choose to implement monthly monitoring then you must also submit, within
30 days of receipt of this notice, copies of the results of your monthly monitoring for the month following
the date of receipt of this notice to the inspector at the address provided.
Comment: Tank #1P: ,
Tank #2R:

Violation 4: 15A NCAC 2N .0603 RLS7; Failure to investigate a suspected release in accordance with federal
regulation 40 CFR 280.52 (as incorporated by 15A NCAC 2N .0603) after the presence of fuel in spill
containment buckets or the degradation of the spill containment equipment to the point where that equipment
can not reasonably be expected to perform its intended function was observed.
Corrective Action(s):
Tank owners or operators must investigate a suspected release as directed below.

1) The condition of the spill containment bucket has deteriorated such that it may need repairing or replacing.
All replaced spill buckets must meet the secondary containment requirements of 15A NCAC 2N .0900. You
must complete the actions listed below.

accordance with the manufacturer's recommendations* or a code of practice developed by a nationally recognized
association. If a testing standard is not available then you must fill the spill containment bucket(s) with clean water
to within 1.5 inches of the top of the spill bucket; mark the water level; wait a minimum of 1 hour and re-check the
level. A spill containment bucket fails the tightness test if there has been any change in level. Submit a copy of the
test results to the inspector at the address provided. If any spill containment bucket fails the tightness test, you must
complete all of the following tasks: (a) Conduct a site check around the spill containment bucket for the tanks listed
above in accordance with 40 CFR 280.52(b) (as incorporated by 15A NCAC 2N .0603) using the sampling protocol
and methodology of the most recent version of the UST Section Guidelines for Site Checks, Tank Closure, and
Initial Response and Abatement and submit, within 30 days of receipt of this notice, a site check report or initial
abatement report (whichever is applicable) to the inspector at the address provided; AND (b) Repair or replace the
spill containment bucket and test the tightness of the spill containment bucket in accordance with the manufacturer's
recommendations, a code of practice developed by a nationally recognized association, or the alternate instructions
listed above if no standard is available. All replaced spill buckets must meet the secondary containment
requirements of 15A NCAC 2N .0900. Within 30 days of receipt of this notice, unless noted differently above,

submit a UST-17B, UST Suspected Release 7 Day Notice, with the results and any supporting information for all
equipment repairs, equipment replacements, tightness test(s), and site check as required in the above sections to the
inspector at the address provided. * Proper disposal of liquids in accordance with State and Federal requirements is
required. See the attached document Recommended ways to dispose of small quantities of petroleum and
petroleum/water mixtures for some suggested methods.

Ranking: H135D
Dear Mr. Fowler: This office acknowledges the receipt of your Comprehensive Site Assessment Report (CSA) for the subject
site on April 1, 2020. Your cooperation is appreciated. The review of the CSA report indicates that the CSA is not complete, and the following comments are provided: - High BTEX concentrations were detected in the upgradient monitoring well MW-5. Type II monitoring(s) must be installed further upgradient to delineate the horizontal extent of groundwater contamination. - Weathered bedrock and bedrock are encountered in all monitoring wells at a dept of approximately 25 feet below ground surface. Since petroleum hydrocarbons have been detected in groundwater samples from the wells in the vicinity of the UST basin, a deep Type III monitoring well needs to be installed to
delineate the vertical extent of groundwater contamination. - Naphthalene was detected at concentration exceeding its corresponding NC 2L standard in three wells around the UST basin. According to the tank information, no diesel or heating oil tank was installed at the facility. The source for naphthalene needs to be addressed in the CSA.
- The well construction record for monitoring well MW-1 indicates that the thickness of weathered bedrock at the bottom of the well is 2 feet, but the thickness of weathered bedrock is depicted in the NW-SE cross section as more than 10 feet in monitoring well MW-1. This cross-section needs to be reconstructed based on the drilling logs. - The groundwater velocity of 325 feet per year beneath the site is very high for this region. Please check the slug test data and reconduct, if necessary, in a monitoring well located in the source area.

The above-mentioned issues need to be addressed in your revised CSA. A complete CSA report should be
submitted to this office no later than May 30, 2020. If you have any questions regarding this letter, please contact Gene Mao at the Guilford County Department of Health and Human Services, 400 W. Market Street, Suite 300, North Carolina 27401 and/or [phone].

4839 West Wendover Avenue, Jamestown, Guilford County, NC 27282

Dear Mr. Mao:

EMS desires to request an extension for the completion of a Comprehensive Site Assessment
(CSA) – Addendum Report and associated activities for the above referenced site. The April 13,
2020 correspondence directing that the work be performed was received electronically on April 14,
2020 with a due date of May 30, 2020. Upon receipt EMS developed a scope of work for submittal
and approval by Guilford County DHHS. A final pre-approval for the directed tasks was completed
on April 27, 2020.

EMS has prepared and submitted a modified well permit application to Guilford County as of April
29, 2020 but has not received a permit to date. Based on the additional work activities remaining to
include well installation (following receipt of permit), top of casing (TOC) survey, groundwater
monitoring/sampling, and report preparation, EMS anticipates finalizing the CSA - Addendum on or
about June 30, 2020.

Please consider our request for an extension. If you have any questions, please contact me at your
earliest convenience.

Sincerely,

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.

N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.

N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL
Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC]
The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.QL-02
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-07
The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
MRL
E
U
J
D

N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL
Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC]
The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.QL-02
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-07
The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.

N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL
Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC]
Analyte biased low in LCS but detected in the reporting limit standard. Since the analyte in the associated
sample was not detected, there is no impact on data quality.
A-07
The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.QL-02
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
