2.0 PREVIOUS INVESTIGATIONS
The site is identified as the former Keffer Collision located at 4800 and 4930 East Independence
Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). ECS previously
conducted a Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205
dated August 29, 2014). ECS identified the following recognized environmental conditions (RECs)
with respect to the subject site.
• The presence of underground hydraulic lifts in the body shop.
• The staining of the concrete in the vicinity of the used oil aboveground storage tank (AST)
in the body shop.
• The historical use as of the site as an auto repair facility/body shop since the 1960s.
• The lack of on -site underground storage tank (UST) closure documentation.
• ECS considered the closed incident associated with the auto facility north of the site to be a
Controlled REC (CREC) due to the Notice of Residual Petroleum as part of the incident
closure; however, the former paint thinner USTs and the lack of UST closure
documentation associated with this facility was considered a REC of the site.
• A former gasoline service station located across Highway 74 adjacent to the site to the
east.
• A closed UST incident was located at the former car wash on the southeastern portion of
the site; however sampling data from UST closure was not available.
Based on a potential real estate transaction and in an effort to determine if the site had been
adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to
conduct an assessment of the site. ECS conducted a Limited Soil and Groundwater
Assessment at the site (ECS Project No. 08-10205-A, dated October 3, 2014) to address the
above mentioned RECs. The sample locations for this assessment are shown on Figure 3.
Based on the results of the soil and groundwater assessment, ECS concluded the following:
• Based on laboratory analysis, a release has occurred from three hydraulic lift tanks
Based on the results of the assessment, ECS recommended the following:
• Removal of the underground lifts and remediation of impacted soil.

• Install and sample two wells in the area of GW-2. The additional assessment indicated that
exceedances of NC2LGWCS in GW-2A appear related to residual petroleum contamination
from the former closed UST incident in this location. The concentrations do not exceed the
applicable DWM Non -Residential Vapor Intrusion Screening levels or GCLs. The MTBE
concentration in sample GW-213 may have originated from the adjacent gasoline service
station across Highway 74 to the east based on groundwater flow and historic groundwater
data for this facility reviewed by ECS. ECS recommended that a copy of this report be
submitted to the current property owner. Based on the laboratory results, ECS understands
that a regulatory reporting condition exists. ECS recommended that the property owner
consult with legal counsel regarding their obligation to report this to the NCDENR
A copy of the Limited Soil and Groundwater Assessment Report and the report of additional
groundwater assessment of the closed UST incident are included in Appendix A.
Based on the findings of the assessment, ECS was contracted to screen soils during removal of
the eight underground lifts and to collect confirmatory soil samples and prepare this report.
3.0 SITE CHARACTERISTICS:
The subject site consists of an approximate 5.51 acre parcel of land that is currently developed
with an automotive dealership (the former Keffer Collision Center) and is located at 4800 East
Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2).
The site is identified as Mecklenburg County Parcel Identification Number 16301305.
According to the Mecklenburg County Online GIS Department, the site is currently owned by
Wilson 301, LLC whom recently acquired the property from Richard W. Keffer Jr. and
Constance O. Keffer. The subject site is improved with three buildings. The first building is an
approximate 28,071 square foot structure that is utilized as offices and body shop and was
constructed in 1968. The second building is an approximate 7,546 square foot building that is
utilized as storage and the spray booth and was constructed in 1986. The third building is an
approximate 9,632 square foot building that is currently vacant and was constructed in 1968.
The site is located in an area that can generally be described as residential/commercial.
As determined from the USGS topographical map, Charlotte East, North Carolina (dated
1967; revised 1988) and Mint Hill (dated 1993), North Carolina quadrangles, the subject site is
situated approximately 740-750 feet above mean sea level with topography sloping to the
southwest. East Independence Boulevard is located along a ridgeline that acts as a surface
water drainage divide. No structures or water bodies are depicted on the site. Based on a
review of the topographic map and observations of general area and site topography,
surface run-off would be expected to flow to the southwest with areas to the northeast
considered topographically upgradient.
The subject site is located within the Charlotte Belt of the Piedmont Physiographic
Province. The soils encountered in this area are the residual product of in -place chemical
weathering of rock presently underlying the site and/or historic depositional events. In
general, shallow unconfined groundwater movement within the overlying soils is controlled
largely by topographic gradients. However, as the groundwater percolates downward, it
becomes controlled by the subsurface geologic conditions. Thus, the direction of

groundwater movement in the deeper aquifers may not be consistent with the reflecting
topography.
Surface waters primarily recharge shallow aquifers by infiltration along higher elevations. Once
in the shallow aquifer, the groundwater typically discharges into streams or other surface
water bodies at lower elevations. The depth of the shallow water table is transient and
can vary with seasonal fluctuations in precipitation. Groundwater movement in the shallow
aquifer is generally from higher to lower elevations. As such, shallow groundwater is
expected to flow generally to the southwest. Based on the presumed groundwater flow
direction, properties located to the northeast appear to be upgradient relative to the site.
However, regional influences may have an impact on groundwater flow. The actual
groundwater flow direction cannot be determined without site -specific information obtained
through the installation of groundwater monitoring wells.
4.0 SOIL REMEDIATION ACTIVITIES
ECS was on -site to observe and document the removal of the eight (2604 through 2611)
underground lifts, screen soils with a photo -ionization detector (PID), and collect confirmatory
soil samples for semi -volatile organic compounds (SVOCs) and extractable petroleum
hydrocarbons (EPH) from beneath each lift after removal. The lifts were removed between
December 2 through 8, 2014. A sample was not collected from beneath lift 2610 during lift
removal, because there was no evidence of a release,'and a soil sample had been previously
collected during the previous limited soil and groundwater assessment (Appendix 1). Elevated
PID readings or petroleum odors were not detected around seven of the eight underground lifts.
However, as a precaution, fill sands immediately surrounding the lifts were excavated for off -site
disposal. Screening of soil adjacent to lift 2611 exhibited elevated PID readings ranging
between 20 to over 200 parts per million (ppm) and petroleum odors. Based on these readings,
additional soils were excavated from the vicinity of lift 2611 and confirmatory soil samples
collected from the base and sidewalls of the excavation after PID readings indicated that the
majority of the impacted soil had been excavated.
The soils were direct loaded into trucks for off -site disposal. The approximate location of the
excavation areas and samples are shown on Figure 4. Soil excavation activities were
terminated based on encountering apparent clean soil based on visual and olfactory
observations and readings from a photoionization detector (PID).
The sampler, wearing a new pair of nitrile gloves, placed the samples in laboratory prepared
containers. Each container was labeled and placed in a cooler containing ice to maintain the
samples at approximately 4° Celsius. The samples were submitted to Prism Laboratories in
Charlotte, North Carolina (North Carolina Certification # 402) for chemical analysis for semi -
volatile organic compounds (SVOCs) using EPA Method 8270 and for extractible petroleum
hydrocarbons (EPH) using the Massachusetts Department of Environmental Protection
(MADEP) Method. Note that samples 2611-S1 through 2611-S4 are identified in the lab report
as samples 2611-51 through 2611-54. Chain -of -Custody Records and the laboratory results are
included in Appendix B.

February 11, 2015
Based on the field readings, impacted soils adjacent to the lifts appeared to have been
excavated. As a precaution, a sample collected from the location indicating the highest field
screening was analyzed on a 48-hour rush. The analysis did not detect petroleum
hydrocarbons, confirming the field findings that impacted soils had been excavated. Based on
these findings additional remediation did not appear warranted, so the excavations were
backfilled as the facility was an active automotive maintenance garage.
Upon receipt and review of the laboratory analytical data, one parameter, extractable petroleum
hydrocarbon (EPH) fraction C11-C22 Aromatics, was detected over North Carolina Department
of Environment and Natural Resource (NCDENR) Soil -to -Water Maximum Soil Contaminant
Concentration (MSCC) in soil samples collected from the beneath lifts 2605 and 2607 after
removal. The sample from lift 2607 also exceeded the Residential MSCC. Analytical results did
not exceed the Commercial MSCC. Based on these results, after the property was acquired by
the new owner, additional soil excavation was conducted in the vicinity of lifts 2605 and 2607 on
January 13 and 14, 2015. Soil was excavated to the maximum extent feasible due to limitations
presented by the ceiling height, and limitations presented by a load bearing wall and utilities
associated with an underground ventilation system.
Following removal of additional soil, on -site personnel collected confirmation soil samples from
the base and sidewall of each excavation. The sampler, wearing a new pair of nitrile gloves,
placed the samples in laboratory prepared containers. The samples were submitted to Prism
for chemical analysis for SVOCs using EPA Method 8270 and for EPH using the MADEP
Method.
Analysis of the soil samples did not detect SVOCs or EPH above the residential, non-residential
or soil -to -water MSCCs in four of the 10 post excavation soil samples. Aromatic hydrocarbons
in the C11-C22 range, were detected at concentrations exceeding the soil to water MSCC in soil
samples 2607-B, 2607S-2, 2607S-3, 2605-B, 2605S-2, and 2605S-4 at concentrations ranging
from 50 mg/kg, in sidewall sample 2605S-2, to 890 mg/kg, in sidewall sample 2607S-3. The
concentrations in samples 2607S-2 and 2607S-3 also exceed the residential MSCC.
Concentrations do not exceed the commercial MSCC. The results are summarized in Table 1,
and the excavation limits are shown on Figure 4. Based on building structures preventing further
excavation, no additional excavation was performed. Note that samples 2607S-2 through
2607S-4 are identified in the lab report as samples 26075-2 through 26075-4 and that sample
2605S-3 is listed twice, with the second listing corresponding to sample 2605S-4. Chain -of -
Custody Records and the laboratory results are included in Appendix B.
5.0 WASTE DISPOSAL
Approximately 231 tons of petroleum impacted soil was removed from the site for off -site
disposal. The soils were disposed by Zebra Environmental at Earthtec in Sanford, North
Carolina. The Waste Disposal Manifests are included in Appendix C.

6.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the results of the investigation, ECS has the following conclusions:
ECS observed the excavation of approximately 231 tons petroleum -impacted soils from the
location of the former underground lifts. Groundwater was not encountered during soil excavation
activities. While petroleum contaminated soil is still present near two the former underground
lifts, it does not exceed the commercial risk levels. Based on the intended use of the site for
commercial uses, soils being under a building with a concrete slab, the availability of public
water to the site and surrounding area, the site being in an urban area, and no groundwater
contamination detected over NC2LGWQS in a monitoring well (UST-1, to evaluate a historic
UST during the previous Limited Soil and Groundwater Assessment) installed as close as
possible downgradient of the lifts (UST-1 GW is shown on Figure 4 and analysis is summarized
in Table 2), ECS recommends no additional assessment and filing a Notice of Residual
Petroleum (NRP) as a viable option to close out the incident. Installation of a well or wells
inside the building would be limited due to the ceiling height and structures, and activities in the
garage area.
ECS recommends that this report be submitted to the NCDENR for their consideration for closure
pending filing of a NRP restricting use of the site to commercial purposes.
7.0 QUALIFICATIONS
The activities and evaluative approaches used in this assessment are generally consistent with
those normally employed in assessments and remediation projects of this type. ECS' evaluation of
site conditions has been based on our understanding of the project information and the data
obtained during our field activities.

1. PROJECT INFORMATION
The site is identified as Keffer Dodge located at 4800 and 4930 East Independence Boulevard
in Charlotte, Mecklenburg County, North Carolina, Figure 1 and 2. ECS previously conducted a
Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205 dated
August 29, 2014). This Phase I ESA is currently being updated to include an additional building
which was added on subsequent to the completion of the Phase I ESA; however, this assessment
includes limited assessment of this parcel based on the information available with regards to this
portion of the site at the time the field work was conducted. ECS identified the following recognized
environmental conditions (RECs) with respect to the subject site.
• The presence of underground hydraulic lifts in the body shop.
• The staining of the concrete in the vicinity of the used oil AST in the body shop.
• ECS considers the historical use as of the site an auto repair facility/body shop since the
1960s to be a REC of the site.
• ECS considers the lack of on -site UST closure documentation to be a REC of the site.
• ECS considers the closed incident associated with the auto facility north of the site to be a
CREC; however, the former paint thinner USTs and the lack of UST closure documentation
associated with this facility is considered a REC of the site.
Subsequent to the Phase I ESA prior to conducting the limited soil and groundwater assessment,
the following potential RECs (to be determined as part of the revised Phase I ESA) were identified.
• A former gasoline services station located across Highway 74 adjacent to the site to the
east.
' A closed UST incident at the former car wash that was not included in the prior Phase I
ESA. A file review is being conducted as part of the revised Phase I ESA.
Based on a potential real estate transaction and in an effort to determine if the site has been
adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to
conduct an assessment of the site. Project information is based on correspondence between
Ms. Ashley Dickerson with Sifen Incorporated and Mr. David Valentine and Mr. Brian Olin with
ECS and the previously cited Phase I ESA.
2. SCOPE OF SERVICES
The soil and groundwater assessment consisted of collecting a soil and groundwater samples
using a Geoprobe® drill rig. The subcontractor used for this project was Carolina Soil
Investigations, LLC (CSI). The soil borings and temporary wells were installed and abandoned
on September 22, 2014.
The Geoprobe® consists of a hydraulic jack mounted on all -terrain vehicle (ATV). The
Geoprobe® is capable of driving various forms of groundwater, soil, and soil -gas sampling
probes into the ground to depths equivalent of auger refusal.

ECS Project No. 08-10205-A
October 3, 2014
Prior to commencing with field activities, ECS contacted North Carolina One Call to locate/mark
public utilities at the site. Required separation distances between subsurface activities and
marked utilities (typically 30-inches) were maintained during the field activities.
As part of this assessment, ECS prepared a site -specific health and safety plan (HASP) for the
site. The HASP documented the known or suspected hazards, applicable personal protective
equipment (PPE) of site personnel, and emergency response procedures. Prior to commencing
with field activities, ECS and its subcontractors and applicable site personnel reviewed the site -
specific HASP.
Soil Sampling
Six soil samples (WO-1, L-1 through L-4, and UST-1) were collected using a Geoprobe®. The
borings were located to assess the RECs identified in ECS's Phase I ESA. Additionally one soil
sample was collected from the saturated zone in boring GW-2 as no groundwater recovered into
the temporary well or Geoprobe® groundwater sampling tool. The sample locations are shown
on Figure 3. Soil samples were collected using a five-foot Macrocore sampler with a dedicated
disposable polyethylene liner. Boring logs, which includes descriptions of the soils encountered
and field screening results, were prepared for each boring and are included in the Appendix.
Upon completion, the borings were properly abandoned and the floor /ground patched with
concrete or asphalt.
The soil samples collected in the field were transferred into a new, clean resealable bag (half full),
and the bag placed in a warm location. Approximately ten minutes after the time of collection, the
bag was opened slightly and the probe of a Photovac Microtip 2000 photoionization detector (PID)
was inserted, and the bag immediately resealed using finger pressure. The meter of the PID was
monitored and the reading recorded. Elevated PID readings were not detected in the borings.
Groundwater Sampling
ECS observed and documented the installation of three temporary monitoring wells (UST-1, GW-1,
and GW-2) at the site (Figure 3). Temporary monitoring well UST-1 was located near the UST
system at the site. Temporary monitoring well GW-2 was located topographically downgradient of
an adjacent gasoline service station and in the location of a closed LUST incident at the former car
wash. Despite saturated soil conditions being observed in boring GW-2 at 15 feet below ground
surface (bgs) after two to three hours less than one inch of water was present in the temporary well
and the water level did not appear to be increasing. Based on no water recovery at this location the
Geoprobe® groundwater sampling tool was used to attempt to obtain a groundwater sample, but
no water could be obtained using this method. Based on no recoverable water at this location a soil
sample was collected from the saturated zone at this location to assess groundwater conditions as
a slight petroleum odor was noted in the saturated zone soils at fifteen feet bgs. Temporary
monitoring well GW-1 was located in a low lying area in the center of the site between UST-1 and
GW-2. The sample locations are shown on Figure 3.

ECS Project No. 08-10205-A
October 3, 2014
The temporary wells were drilled approximately five to ten feet into the groundwater table
(encountered at approximately 15 to 20 feet bgs) to an approximate depth of 25 feet bgs. The
temporary wells were constructed with one -inch I.D. Schedule 40 PVC flush -threaded casing and
screen. The PVC screen and casing was lowered into the open borehole. A fifteen -foot length of
slotted well screen with machined 0.010-inch slot widths and a threaded bottom plug were installed
at the bottom of each well. The screens were installed to a depth such that the screened interval
intersected the estimated groundwater surface. A solid section of PVC casing was placed above
the screened interval and extended to a point just below the ground surface. The annular space
around each well was filled with a washed and graded medium sand to approximately two feet
above the top of the screen. A boring log was prepared for each temporary monitoring well, which is
included in Appendix II.
The temporary monitoring wells were sampled using a peristaltic pump and new, dedicated
polyethylene tubing. Immediately after collection, the groundwater samples were transferred into
sample containers provided by the laboratory. Upon completion, the temporary groundwater
points were abandoned after the groundwater samples were collected.
The soil and groundwater samples were placed into laboratory prepared containers. The sample
containers were labeled with ECS project number, sample identification, sample date and time,
and requested analytical analysis. The containers were placed into protective packaging
material and placed into a cooler with ice to maintain the samples at approximately 4° Celsius
(CO). The samples were submitted to (Prism Laboratories located in Charlotte, North Carolina
(North Carolina Certification # 402) for chemical analysis. The soil and groundwater samples
were analyzed for volatile organic compounds (VOCs) using EPA Method 8260, semi -volatile
organic compounds (SVOCs) using EPA method 8270, and extractable and volatile petroleum
hydrocarbons (EPHNPH) using the Massachusetts Department of Environmental protection
(MADEP) methods. ECS maintained proper chain -of -custody (COC) procedures throughout the
sample collection and transportation process. A copy of the COC is included in the Appendix.
3. RESULTS
Laboratory analysis of soil samples WO-1, L-2, L-4 and UST-1 detected VOCs, SVOCs,
EPHNPH and metals above laboratory detection limits; however, the concentrations do not
exceed the applicable North Carolina Maximum Soil Contaminant Concentrations (MSCCs).
Laboratory analysis of groundwater samples UST-1 GW and GW-1 detected VOCs, SVOCs, and
EPHNPH above laboratory detection limits; however, the concentrations do not exceed the
applicable North Carolina 2L Groundwater Quality Standards (NC2LGWQS) or Division of
Waste Management (DWM) Non -Residential Vapor Intrusion Screening Levels.
Laboratory analysis of soil samples L-1, L-3 and L-4 detected C-11-C22 Aromatics and Arsenic
above laboratory quantitation/detection limits; with the concentrations in samples L-1, L-3 and L-
4 of C-11-C22 Aromatics ranging from 270 to 360 milligrams per kilogram (mg/Kg) exceed the
Soil to Water MSCC of 31 mg/Kg and concentrations of arsenic in samples L-1 and L-3 ranging
from 2.5 to 3.6 mg/Kg which exceed the North Carolina Department of Environment and Natural
Resources (NCDENR) Inactive Hazardous Sites Branch (IHSB) Industrial Soil Remediation
Goal of 2.4 mg/Kg. The remaining compounds detected do not exceed the applicable soil
cleanup criteria.

Laboratory analysis of sample GW-2 detected several VOCs, SVOCs, and EPH/VPH above
laboratory detection limits; with the concentration of 1-methylnaphthalene exceeding the Soil to
Water MSCC. This sample was collected in the saturated zone to assess groundwater as
sufficient groundwater for sampling could not be recovered. The results of this sample are also
listed on the groundwater table for comparison purposes; however, the results were not
compared to NC2LGWQS since it was a soil analysis. This sample was located near the
location of the former closed LUST incident. A summary of the laboratory analytical results is
included in Tables 2 and 3. The laboratory data sheets are included in the Appendix.
4. CONCLUSIONS
Based on the results of the soil and groundwater assessment, ECS concludes the following:
• On September 22, 2014, ECS observed and documented the advancement of seven soil
borings, one groundwater boring and the installation of three monitoring wells at the site.
• Evidence of a release (petroleum/chemical odors, staining, sheens, elevated readings on
the PID) was identified in boring GW-2 consisting of petroleum odors in the saturated zone
of boring GW-2. Evidence of a release was not identified in the remaining borings during
assessment activities.
• Groundwater was encountered at an approximate depth of 15 to 20 feet bgs.
• Drilling refusal was encountered at depths ranging from 15 to 24 feet bgs.
• Six soil, two groundwater, and one soil sample from the saturated zone (GW-2) to asses
groundwater were submitted to a certified laboratory for chemical analysis for VOCs,
SVOCs, EPH/VPH, and/or metals.
• Laboratory analysis of soil samples detected targeted analytes at concentrations that
exceed the applicable North Carolina MSCC in samples L-1, L-3, L-4 and GW-2..
• Laboratory analysis of groundwater samples detected VOCs and SVOCs above laboratory
reporting limits, but did not detect targeted analytes at concentrations that exceed the
NC2LGWQS. Evidence of a groundwater impact was identified based on odors and soil
smapling in the saturated zone in boring GW-2. This sample was located in the location of
the closed former LUST incident. An off -site gasoline service station is also located on an
adjacent property across Highway 74 topographically upgradient of this location.
• The extent of impact to the site has not been fully delineated. Additional assessment would
be necessary to fully delineate the extent of impact to the site.

ECS Project No. 08-10205-D
August 21, 2015
RELEASE INFORMATION
Soil assessment indicated the presence of impacted soil by three of the eight former underground
lifts. The volume of the release is not known; however, approximately 231 tons of petroleum
impacted soil was previously removed from the site. Based on the findings of an Initial Abatement
Action Report dated February 11, 2015, the NCDENR in a letter dated March 19, 2015 requested
that a Limited Site Assessment be completed.

Limited Site Assessment Report
Former Keffer Collision
4800 East Independence Boulevard,
Charlotte, Mecklenburg County, North Carolina
ECS Project No. 08-10205-D
August 21, 2015
2.0 SITE HISTORY
The site is identified as the former Keffer Collision located at 4800 and 4930 East Independence
Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). ECS previously
conducted a Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205
dated August 29, 2014). ECS identified the following recognized environmental conditions (RECs)
with respect to the subject site.
• The presence of underground hydraulic lifts in the body shop.
• The staining of the concrete in the vicinity of the used oil aboveground storage tank (AST)
in the body shop.
• The historical use as of the site as an auto repair facility/body shop since the 1960s.
• The lack of on -site underground storage tank (UST) closure documentation.
• ECS considered the closed incident associated with the auto facility north of the site to be a
Controlled REC (CREC) due to the Notice of Residual Petroleum as part of the incident
closure. However, the former paint thinner USTs and the lack of UST closure
documentation associated with this facility was considered a REC of the site.
• A former gasoline service station located across Highway 74 adjacent to the site to the
east.
• A closed UST incident was located at the former car wash on the southeastern portion of
the site; however sampling data from UST closure was not available.
Based on a potential real estate transaction and in an effort to determine if the site had been
adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to
conduct an assessment of the site. ECS conducted a Soil and Groundwater Assessment at the
site (ECS Project No. 08-10205-A, dated October 3, 2014) to address the above mentioned
RECs. The sample locations for this assessment are shown on Figure 3 and 4. Based on the
results of the soil and groundwater assessment, ECS concluded the following:
• A release had occurred from three hydraulic lift tanks (Tables 1 and 2).
Based on the results of the assessment, ECS recommended the following:
• Removal of the underground lifts and remediation of impacted soil.

Former Keifer Collision
4800 East Independence Boulevard,
Charlotte, Mecklenburg County, North Carolina
ECS Project No. 08-10205-D
August 21, 2015
• Install and sample two wells in the area of GW-2. The additional assessment indicated that
exceedances of NC2LGWQS in GW-2A appear related to residual petroleum contamination
from the former closed UST incident in this location. The concentrations do not exceed the
applicable DWM Non -Residential Vapor Intrusion Screening levels or GCLs. The MTBE
concentration in sample GW-213 may have originated from the adjacent gasoline service
station across Highway 74 to the east based on groundwater flow and historic groundwater
data for this facility. This contamination was determined to be consistent with the previous
release from the UST and also from an off -site source, and further assessment of this area
was not recommended. This area is not included in this report and was included as an
attachment to the Initial Abatement Action Report (IAAR).
Based on these findings, Sifen Incorporated requested ECS oversee the removal of the
underground lifts and impacted soil in the vicinity of the lifts and collect confirmatory soil samples.
Approximately 231 tons of petroleum impacted soil was removed from the site for off -site disposal
in January 2015. Due to depth constraints or structural limitations, complete removal of impacted
soil was not possible in some of the areas. ECS submitted an IAAR to the North Carolina
Department of Environment and Natural Resources (NCDENR) on March 11, 2015. A copy of the
Soil and Groundwater Assessment Report and the report of additional groundwater assessment of
the closed UST incident was included with the IAAR.
The NCDENR issued a letter based on the IAAR requesting that a Limited Site Assessment
(LSA) be conducted. Based on this letter, ECS was contracted to conduct the LSA sampling
and prepare this report.
3.0 SITE CHARACTERISTICS:
The subject site consists of an approximate 5.51 acre parcel of land that is currently developed
with an automotive dealership (the former Keffer Collision Center) and is located at 4800 East
Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2).
The site is identified as Mecklenburg County Parcel Identification Number 16301305.
According to the Mecklenburg County Online GIS Department, the site is currently owned by
Wilson 301, LLC whom recently acquired the property from Richard W. Keffer Jr. and
Constance O. Keffer. The subject site is improved with three buildings. The first building is an
approximate 28,071 square foot structure that is utilized as offices and body shop and was
constructed in 1968. The second building is an approximate 7,546 square foot building that is
utilized as storage and the automobile paint spray booth and was constructed in 1986. The
third building is an approximate 9,632 square foot building that is currently vacant and was
constructed in 1968. The site is located in an area that can generally be described as
residential/commercial.
As determined from the USGS Topographical Map, Charlotte East, North Carolina (dated
1967; revised 1988) and Mint Hill (dated 1993), North Carolina Quadrangles, the subject site is
situated approximately 740-750 feet above mean sea level with topography sloping to the
southwest. East Independence Boulevard is located along a ridgeline that acts as a surface
water drainage divide. No structures or water bodies are depicted on the site. Based on a
review of the topographic map and observations of general area and site topography,
FA

August 21, 2015
surface run-off would be expected to flow to the southwest toward with areas to the
northeast across Independence Boulevard considered topographically upgradient.
The subject site is located within the Charlotte Belt of the Piedmont Physiographic
Province. The soils encountered in this area are the residual product of in -place chemical
weathering of rock presently underlying the site and/or historic depositional events. In
general, shallow unconfined groundwater movement within the overlying soils is controlled
largely by topographic gradients. However, as the groundwater percolates downward, it
becomes controlled by the subsurface geologic conditions. Thus, the direction of
groundwater movement in the deeper aquifers may not be consistent with the reflecting
topography.
Surface waters primarily recharge shallow aquifers by infiltration along higher elevations. Once
in the shallow aquifer, the groundwater typically discharges into streams or other surface
water bodies at lower elevations. The depth of the shallow water table is transient and
can vary with seasonal fluctuations in precipitation. Groundwater movement in the shallow
aquifer is generally from higher to lower elevations. As such, shallow groundwater is
expected to flow generally to the southwest on the southwest side of Independence
Boulevard. Based on the presumed groundwater flow direction, properties located to the
northeast appear to be upgradient relative to the site. However, regional influences may
have an impact on groundwater flow. The actual groundwater flow direction cannot be
determined without site -specific information obtained through the installation of groundwater
monitoring wells.
4.0 RISK CLASSIFICATION AND LAND USE
Submit the following questionnaire in its entirety. Answer all questions completely. Attach
additional pages as needed to fully explain answers. Base answers/explanations on information

5.0 RECEPTOR INFORMATION
ECS conducted a water supply well survey within a 1,500 foot radius of the source area. The
survey was conducted by performing a driving and walking reconnaissance, interviews with City
of Charlotte personnel, and distribution of water supply well questionnaires to owners of
properties located within 500 feet of the source area, concerning water supply and usage.
Based on the information obtained and discussed below, ECS did not identify properties that
potentially contain water supply wells.
Driving and Walking Reconnaissance
ECS conducted a reconnaissance within the radius area for observations of water supply wells
and evidence of municipal supplied water availability (water meters, meter boxes, fire hydrants,
etc.). ECS did not observe evidence of water supply wells. Municipal water service was
observed within the 1,500 foot radius of the source area.
Interviews with City of Charlotte Personnel
ECS inquired as to municipal water availability for the site and surrounding area. Based on
discussions with Charlotte -Mecklenburg Utilities on April 9, 2012, municipal water is available to
the site and surrounding area within the 1,500 foot radius of the source area. ECS also
reviewed the Mecklenburg County well information system which did not identify water supply
wells within the vicinity of the site.
ECS submitted water supply well questionnaires to each property owner within a 500 foot radius
of the source area. ECS sent water supply well questionnaires via certified mail to twenty-eight
property owners. Six (4800, 4812, 4816, 4836, 4841, and 4805 Charleston Drive) were
returned undelivered, and fifteen return receipts were received. As of the date of this report,
four recipients (owners of 4905, 4911, and 4825 Charleston Drive) responded via telephone and
indicated they are on city water and do not have a well. Five (4824, 4837, 4833, 4905, and 4825
Charleston Drive) completed questionnaires were returned. According to the information within
the questionnaires, these properties did not contain water supply wells. A copy of the letter
submitted, the recipient list, the certified mail receipts, and responses received are included in
Appendix B.
Summary of Water Usage
Based on the available information, ECS did not identify wells used for drinking water within
1,500 feet of the source area (Figure 5). According to interviews with City of Charlotte
personnel, municipal supplied water is available to the site and the area within a 1,500 foot
radius of the source area. Water supply wells were not identified on the Mecklenburg County
Well Information System.
Surface Water
An unnamed tributary of McMullen Creek is located approximately 1,000 feet to the southwest
of the source area (Table 3). The tax map shows a drainage feature on the site, approximately
500 feet south of the source area. This was not observed during the site reconnaissance, and
appears related to the sewer system which is located in that approximate area.

Charlotte, Mecklenburg County, North Carolina
ECS Project No. 08-10205-D
August 21, 2015
Wellhead Protection Areas
The site is not located in a drinking water assessment area, and no public water supplies were
identified as determined from the NCDENR Division of Water Resources Public Water Supply
Section.
Deep Aquifers in the Coastal Plain Phvsiographic Region
The site is not located within the Coastal Plain physiographic region as designated on the map
entitled "Geologic Map of North Carolina" published by the Department in 1985.
Subsurface Structures
Several subgrade structures consisting of natural gas, water, sewer, and electrical lines were
identified on the site (Figure 2). Based on their depths, location, and observations at the site as
compared to the identified impacted area, the identified subsurface structures do not have the
potential to be conduits for contaminant transport.
Land Use
Property Owners and Occupants
As contamination in groundwater was not detected above North Carolina 2L Groundwater
Quality Standards (NC2LGWQS) contamination is not expected to migrate off -site. Table 4 is a
summary of nearby property owners.
Sensitive Land Use Features
ECS did not identify features sensitive to impact from the release (schools, daycare centers,
nursing homes, hospitals, playgrounds, parks and recreation areas, churches, camps and other
places of assembly) within 1,500 feet of the source of the release.
Site Geology and Hvdrogeologv
The site is located within the Charlotte Belt of the Piedmont Physiographic Province as
described in Section 3.0 of this report. Soils consisted of dense silty sands. Boring logs from
well installation are included in Appendix A. Groundwater was encountered between 17.6 and
22.5 feet below ground surface (bgs) (Table 5). Since there is insufficient groundwater data for
the site, the groundwater flow direction cannot be determined at this time. Based on surface
topography, the shallow groundwater is assumed to flow to the southwest toward an unnamed
tributary of McMullen Creek (Figure 1).
6.0 FIELD ACTIVITIES
On July 7, 2015, ECS personnel observed the advancement of soil boring MW-1 and MW-2 in the
vicinity of previously identified petroleum impacts (Figure 4). The borings were advanced by
Carolina Soil Investigations, LLC (CSI), a North Carolina certified driller, using a Geoprobe© drill rig
with auger capabilities. A boring log, well construction diagram and record were prepared and are
included in Appendix A. Soils were screened with a PID and samples collected based on field
screening in 5 foot intervals beneath the former excavation backfill material.
After terminating the borings at approximately 35 feet below ground surface (bgs), the permanent
groundwater monitoring wells (MW-1 and MW-2, Figure 4) were installed. Each well was
constructed with 2-inch I.D. Schedule 40 PVC flushed -threaded casing and screen. The PVC

Limited Site Assessment Report

Charlotte, Mecklenburg County, North Carolina
ECS Project No. 08-10205-D
August 21, 2015
screen and casing were lowered to the bottom of the borehole. A 15-foot length of slotted well
screen with machined 0.010-inch slot widths and threaded bottom plug was installed at the bottom
of the well. A solid section of PVC casing was placed above the screened interval and extended to
a point approximately 6 inches below the ground surface. The top of the casing was fitted with an
expandable lockable cap. The annular space around the well was filled with washed fine filter sand
to approximately two feet above the top of the screen. A minimum 2-foot thick seal of bentonite
pellets was placed immediately above the sand pack. The top of the well casing was equipped
with a lockable, water -tight well plug. The well was finished with concrete and a flush -mount steel
manhole was installed in a concrete pad to protect the well. A monitoring well construction
diagram was prepared for the well and is included in Appendix A.
6.1 Soil Sampling
Soil samples were collected at 16, 21, and 26 feet below ground surface (bgs) in MW-1 and MW-2,
as fill extended to approximately 15 feet bgs and saturated soils were encountered at
approximately 27 to 30 feet bgs (Table 5 and 6). Soil samples were analyzed for semi -volatile
organic compounds (SVOCs) using EPA Method 8270, and Massachusetts Department of
Environmental Protection (MADEP) extractable petroleum hydrocarbons (EPH).
Hydrocarbons in the C11 to C12 aromatic range were detected at concentrations above North
Carolina Soil -to -Groundwater Maximum Soil Contaminant Concentration (MSCC) in MW-1-A.
COncentrations did not exceed the Residential or Commercial MSCC. Concentrations in deeper
samples between MW-1A and the water table and in MW-2 did not exceed the MSCCs. The
results are summarized in Table 7 and the lab results included in Appendix C.
6.2 Groundwater Sampling
On July 8, 2015, after installation and allowing for recovery of water levels, the wells were checked
for evidence of free phase petroleum product using a bailer. Free phase petroleum product was
not detected. Water was purged from the wells and a groundwater samples were collected from
MW-1 and MW-2. Groundwater samples were analyzed for SVOCs and MADEP EPH.
Several SVOCs and MADEP EPH compounds were detected at concentrations above laboratory
reporting limits; however the concentrations are not above the NC2LGWQS. The results are
summarized in Table 8 and the lab results included in Appendix C.
7.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the results of the investigation, ECS has the following conclusions
• ECS previously observed the excavation of approximately 231 tons petroleum -impacted
soils from the location of the former underground lifts. Groundwater was not encountered
during soil excavation activities. Due to site constraints, petroleum contaminated soil
above residential criteria is still present near two former underground lifts, though it does
not exceed the commercial risk levels. Based on the intended use of the site for
commercial uses, and soils being under a building with a concrete slab there is no risk of
exposure to the public to these soils, provided there is no further excavation in this area.
• Based on results of groundwater sampling, the former hydraulic lifts have not resulted in
impacts to groundwater above NC2LGWQS. Since there is no record of groundwater

impacts above NC2LGWQS, no water supply wells were identified within 1,000 feet of
the source area, and municipal water is available to the site and surrounding area, ECS
does not recommend additional assessment.
• ECS recommends that this report be submitted to the NCDENR-Mooresville Regional
Office for their consideration for no additional assessment and closure of the incident
pending filing of a Notice of Residual Petroleum (NORP).
8.0 QUALIFICATIONS
The activities and evaluative approaches used in this assessment are generally consistent with
those normally employed in assessments and remediation projects of this type. ECS' evaluation of
site conditions has been based on our understanding of the project information and the data
obtained during our field activities.

We represent Richard Keffer, Jr., widower (his wife Constance Keffer passed away in
2014). I am in receipt of your letter dated March 19, 2015 (copy enclosed), concerning the
property located at 4800 East Independence Boulevard in Charlotte.
Please be advised that Mr: Keffer sold the referenced property on December 17, 2014, to
Wilson 301, LLC, per the enclosed Deed. Prior to the purchase, Wilson 301, LLC engaged in
ECS Carolinas, LLP to perform an environmental investigation of the property, and it is our
understanding that they were satisfied with the results of said investigation, hence their ultimate
purchase of the property. My assumption is that the initial Abatement Action Report received by
your office referenced in your letter was performed by ECS on behalf of Wilson 301, LLC. As
Wilson 301, LLC is the owner of the property and presumably prepared the report in question,
please contact them to discuss this matter.

Incident Number: 40464
Risk Classification: Low
Dear Mr. Godwin:
North Carolina General Statute (NCGS) 143B-279.9 and 143B-279.11 require a Notice of
Residual Petroleum (Notice) to be filed with the Register of Deeds in Mecklenburg County, where the
release is located, when a release from an underground storage tank has not been remediated to below
"unrestricted use standards". The Notice is required either prior to conveyance of a contaminated
property or prior to receiving a Notice of No Further Action. "Unrestricted use standards" for
groundwater are the groundwater quality standards and interim standards contained in Title 15A NCAC
2L .0202, and "unrestricted use standards" for soil are the residential maximum soil contaminant
concentrations (MSCCs) established in Title 15A NCAC 2L .0411.
The Notice must be prepared in accordance with the attached instructions and format. It must
contain a legal description of the property containing the source of contamination and legal descriptions
of any other properties which you own (or control) which are contaminated by the release. The Notice
must also include appropriate land use restrictions for these properties. In addition, the Notice must
identify all other properties (adjacent, adjoining, downgradient, etc.) on which contamination is known to
exist at the time the Notice is prepared.
If seeking incident closure, the Notice must be sent to this regional office of the UST Section
within 30 days of the date of this letter for approval and notarization. The approved and notarized Notice
must then be filed by you with the Register of Deeds, and a certified copy of the filed Notice must be
submitted to this office within 30 days of its return to you. ''
Effective October 1, 2004, the Department requires that all work following the submittal of the
Limited Site Assessment Report (Title 15A NCAC 2L .0405) be preapproved if State Trust Fund
reimbursement is anticipated. To comply with this requirement, a completed Preapproval/Claim
Authorization Form, encompassing the required remedial activities, must be received in this office within
14 days of the date of this letter. Upon completion of the preapproved activities, you should submit your

I do not but it is not consistent with hydraulic oil or site use. It is often used as an antiseptic such as in hand sanitizers,
so is likely a sampling or lab contaminant. Gloves were worn during sampling.

Brian,
Do you know what 4-chloro-3-methyl phenol is from?
It's detected in both groundwater samples.
Thanks,

Hi Brian,
I'm hoping to get a little more information regarding the IAA Report we received...
According to the report L-1, L-3 and LA soil samples had exceeded soil -to -groundwater standards but I couldn't tell if
these areas were subsequently excavated as part of the IAA work (Figure 4 of the report shows L-3 outside the area
excavated, and the figure doesn't show where L-1 and LA were relative to the excavations)?
L-1 and LA were excavated and were located in excavations 2607 and 2605. L-3 was excavated and was located in
excavation 2611. The location shown as L-3 on Figure 4 was actually L-2.
What were the dimensions of the final excavation pits for the three leaking lifts?
The approximate dimensions were as follows:
2611 — 12'xl2'xl4'deep
2605—10'xl2'x14'deep
2607—13'xl5'xl4'deep
14 feet was the maximum feasible excavation depth due to the garage height and equipment that could fit inside the
garage.
Have you reported the arsenic levels to the Inactive Hazardous Sites branch?
This was the first report submitted. The only know source at the site is those discussed in the report and these samples
were adjacent to the underground lifts which is the only known source in this area.
I could not find groundwater sampling results for the GW-2A and GW-213 wells in the report...
GW-2A & GW-2B were on the opposite end of the site related to other areas at the site and not near the items
addressed in this report. Specifically they addressed an off -site source and confirming groundwater concentrations
relative to a closed LUST incident on the other portion of the site, several hundred feet away from the garage. It was
detailed in a separate report to the client which is attached.
Once I have this information I will complete my review of the report.
Thanks for your help,

Brett
