October 16, 2017
1.0 BACKGROUND INFORMATION
The site is located at 3600 East Independence Boulevard in Charlotte, Mecklenburg County,
North Carolina (Figure 1 and Figure 2). According to a Phase II Environmental Site Assessment
(ESA) performed by Hart & Hickman (H&H) in June, 2017, the site included a Mr. Transmission
automotive service facility in the northwestern portion of the site. Four in -ground hydraulic lifts
were located in the building and were reportedly installed at the time of initial building construction
in the late 1950s or early 1960s. During the Phase II ESA, six soil samples were collected
adjacent to the lifts (SB-1, SB-2, SB-3, SB-6, S13-7, and SB-8) and analyzed for total petroleum
hydrocarbons as diesel range organics (TPH-DRO). During the Phase II ESA activities, three
temporary monitoring wells were installed at the site. Soil boring SB-7 was converted to TMW-
1, TMW-2 was installed in the central portion of the site, and TMW-3 was installed along the
eastern site boundary. Depth to groundwater ranged from approximately 14.10 ft below top of
casing (TOC) at TMW-1 to 16.00 ft below TOC at TMW-3.
The groundwater samples collected from TMW-2 and TMW-3 were analyzed for VOCs by EPA
Method 8260. The groundwater sample collected from TWM-1 was analyzed for VOCs by EPA
Method 8260, SVOCs by EPA Method 8270, TPH-GRO, TPH-DRO, and TPH-ORO by EPA
Method 8015, and extractable petroleum hydrocarbons (EPH) by Massachusetts Department of
Environmental Protection (MADEP) method.
Analytical results indicated the presence of TPH-DRO in the soil samples collected from soil
borings SB-6 and SB-7 at concentrations above the Action Level of 100 mg/kg. Soil borings SB-
6 and SB-7 were advanced adjacent to closed in -place hydraulic lifts located near the rear (west
side) of the building. TPH-DRO was not detected above the State Action Levels in the
remaining samples. Additionally, TPH-ORO was detected in several soil samples at
concentrations ranging from 11.2 mg/kg (SB-8) to 1,860 mg/kg (SB-6). However, an Action
Level for TPH-ORO has not been established. Analytical results did not indicate the presence
of PAHs or TPH-GRO in the samples collected during the Phase II ESA activities.
Analytical results indicated the presence of 1,2,4-Trimethyl benzene in the groundwater sample
collected from TMW-1 at a concentration of 1.81 pg/L which his below the Groundwater
Standard of 400 tag/L and the GCL of 28,500 fag/L. Additionally, Methyl tert-butyl ether (MTBE)
was detected in the groundwater sample collected from TMW-2 at a concentration of 1.14 ug/L
which is below the Groundwater Standard of 20 fag/L and the GCL of 20,000 fag/L. Analytical
results of the groundwater sample collected from TMW-1 indicated the presence of TPH-DRO at
a concentration of 1,190 fag/L. However, a Groundwater Standard or a GCL have not been
established for TPH-DRO. As such, H&H requested the laboratory to analyze the sample for
EPH. Analytical results did not indicate the presence of EPH C9-C18, EPH C11-C22, or
EPHC19-C36 at concentrations above laboratory reporting limits. However, it should be noted
that the laboratory detection level for EPH C11-C22 was 400 fag/L which is above the
Groundwater Standard of 200 fag/L.

2.0 SITE CHARACTERISTICS
The site is located at 3600 East Independence Boulevard in Charlotte, Mecklenburg County,
North Carolina. The site is located in an urban/commercial area of Mecklenburg County. Four
in -ground hydraulic lifts were located inside the former Mr. Transmission automotive service
facility (Figure 3)
3.0 SCOPE OF SERVICES
The scope of services consisted of closuring four hydraulic lifts by removal and removal and off -
site disposal of petroleum hydrocarbon impacted soil associated with the lifts. A double post
hydraulic lift and a single post lift were located on the western side of the garage and two single
post lifts were located on the eastern side of the former garage. The single post lifts had, at
some point, replaced double post lifts. The subcontractor used for this project was CCI
Environmental. Field activities were conducted on September 5 and 6, 2017. Site Photographs
are included in Appendix A.
4.0 SITE HISTORY AND CHARACTERIZATION
4.1 Lift Information
Four in -ground hydraulic lifts with five cylinders were removed on September 5, 2017. The UST-2
Form is included in Appendix B.
4.2 Description of Release
Based on the field screening instrument, stained soil, petroleum odors, and previous soil sample
analytical results, a release was detected.
4.3 Site Characteristics
The nearest residence is located approximately 300 feet southwest of the release. Oakhurst
Elementary School is located approximately 3,000 feet south of the release. As determined
from the USGS Topographic Map, Charlotte East, North Carolina Quadrangle (Figure 1),
elevations at the site range from approximately 690 feet above mean sea level near the
southeastern boundary to 720 feet above mean sea level near the northwestern boundary of the
site. An unnamed tributary to Briar Creek is located approximately 800 feet southwest of the
release area. Surface runoff on the site is generally to the south-southwest.
According to the Geologic Map of North Carolina (1985), the subject property is situated in the
Charlotte and Milton Belts. The soils encountered in this area are the residual product of in -
place chemical weathering of rock presently underlying the site. In general, shallow unconfined
groundwater movement within the overlying soils is controlled largely by topographic gradients.
However, as the groundwater percolates downward to the bedrock, it becomes controlled by the
orientation of the rock fracture systems. Thus, the direction of groundwater movement may not

be consistent with the reflecting topography. Recharge occurs primarily by infiltration along
higher elevations and typically discharges into streams or other surface water bodies. The
elevation of the shallow water table is transient and can vary with seasonal fluctuations in
precipitation. Movement of groundwater under water table conditions is generally from higher to
lower elevations. As such, shallow groundwater would be expected to flow to the south-
southwest beneath the site.
5.0 UST CLOSURE AND INITIAL RESPONSE
On September 5, 2017, ECS personnel met Contaminant Control, Inc. (CCI) of Salisbury, North
Carolina at the site to begin closure activities. Closure activities included the closure by removal
of four in -ground hydraulic lifts. CCI used a vacuum truck and removed 78 gallons of liquid from
the lifts. The liquid was manifested and taken offsite for disposal at CCI's facility in Salisbury,
North Carolina. A copy of the liquid material manifest is included in Appendix C.
A tracked excavator was used to complete the removal activities. Overlying concrete and soil were
removed with the excavator to expose the lifts. The lifts were removed from the exaction, cleaned,
and inspected. No holes or evidence of a release was observed on the surface of the lifts. The lifts
measured 1.5 feet in diameter and 7 feet in length. The lifts were transported by CCI to Foss
Recycling in Salisbury, North Carolina for disposal. The lift disposal manifest is included in
Appendix D.
6.0 SITE INVESTIGATION
6.1 Field Screening
Following removal of the lifts from the eastern portion of the building, representative samples of
soil from the base of the excavation were collected and screened using the probe of a Foxboro
Model 2020 toxic vapor analyzer which is a flame ionization detector (FID). A portion of soil
from each location was placed in a re -sealable plastic bag for the purpose of field screening.
Each plastic bag was placed in a warm location for approximately ten minutes to allow the
headspace in the bag to equilibrate. The probe of the FID was inserted into the bag, and the
bag was immediately resealed. The FID meter was monitored and the readings recorded. The
readings are summarized below.

The NCDEQ release reporting form (UST 61) is included in Appendix B.
Because the soil from the lift area on the western side of the building was known to be impacted,
initial FID readings were not recorded.

6.2 Sample Collection and Analysis
After removing the lifts from the ground, the excavator was used to collect soil samples (HL-3
and HL-4) from beneath the location of the lifts. Though analysis of samples collected from this
area by H&H (samples S13-2 and S13-3) did not detect TPH-DRO above the State Action Level,
elevated FID readings and a distinct petroleum odor was noted in the soil. The samples were
collected from an approximate depth of 7 to 8 feet below ground surface (bgs). The ECS
personnel on site manually collected the samples from the bucket of the excavator. The sampler
wore new, disposable nitrile gloves at each sample location. The approximate location of the
samples is shown on Figure 4. Samples from lifts 1 and 2 (LH-1 and LH-2) were not collected
for TPH analysis since the previously collected samples (SB-6 and SB-&) by H&H from this area
detected TPH-DRO above the State Action Level.
The soil samples were placed into laboratory prepared glass containers. After being filled, the
sample containers were labeled and placed into a cooler containing ice to maintain the samples
at approximately 4° Celsius. The samples were transported to Research and Analytical
Laboratories (R&A) in Kernersville, North Carolina to be analyzed for total petroleum
hydrocarbons (TPH) using EPA Methods 8015/3550 diesel range organics (DRO). The
samples were transported to the laboratory under chain of custody. A copy of the Chain of
Custody Record is included in Appendix D.
6.3 Soil Excavation, Transportation and Disposal
On September 5, 2017, ECS observed the excavation and loading of approximately 79 tons of
impacted soil from two separate excavations for off -site disposal (Figure 4). One of the areas
was located on the eastern side of the building in the area where two inactive lifts were located
(H&H SB-2 and SB-3) and the second was located at the rear of the building where the double
post lifts and an inactive and active lift were located. As soil was being excavated from the area
of the double post lifts (H&H samples S13-6 and S13-7), the impacted soil extended to the north
toward the inactive lift and the recently inactivated lift.
CCI transported the soil to Earthtec of NC, Inc. in Sanford, North Carolina for disposal. The
Non -Hazardous Manifests and transportation weight tickets are included in Appendix C.
6.4 Confirmation Soil Sampling
Following the excavation activities, soil samples SW-1 through SW-4 and B-1were collected
from the sidewalls and base of the western excavation and soil samples SW-1A through SW-4A
and B-2 were collected from the sidewalls and base of the eastern excavation. The sidewall
samples were collected from approximately 12-13 feet bgs and the base samples were
collected from a depth of 14-15 feet bgs (close to the water table surface as measured in TW-1).
The sample locations are shown on Figure 4.
The soil samples were collected while the sampler was wearing a new pair of disposable nitrile
gloves for each sample collected. The soil samples were placed directly into laboratory
prepared containers. The soil sample containers were labeled and placed into protective

packaging material and placed into a cooler with ice to maintain the samples at approximately
4° Celsius (C°). the samples were transported to R&A to be analyzed for semi -volatile organic
compounds (SVOCs) using EPA Method 8270BNA (base neutrals and acid extractable), and
extractable petroleum hydrocarbons (EPH) using the Massachusetts Department of
Environmental Protection (MADEP) Methods.
Groundwater was not encountered during closure activities. The excavations were filled with
the overburden and off -site fill material and capped with stone.
7.0 LABORATORY ANALYTICAL RESULTS
7.1 Lift Closure Soil Sample Results
Laboratory analytical results of soil samples HL-3 and HL-4 did not detect TPH above the
laboratory quantitation limit. The results are summarized on Table 1 and the laboratory
analytical data sheets are included in the Appendix D.
7.2 Confirmation Soil Sample Results
Laboratory analysis of side wall soil samples SW-1, SW-2, and SW-4 detected C11-C22 range
aromatic petroleum hydrocarbons at concentrations that exceed their Soil -to -Groundwater
Maximum Soil Contaminant Concentrations (MSCCs) with the concentrations in samples SW-1
and SW-2 exceeding their Residential MSCCS. EPH range hydrocarbons were detected in the
base sample but at concentrations below the soil -to -groundwater MSCC. The analysis did not
detect SVOCs or EPH range hydrocarbons above the laboratory reporting limits in the samples
collected from the eastern excavation. The results are summarized on Table 1 and the
laboratory analytical data sheets are included in the Appendix D.
8.0 CONCLUSIONS
An ECS professional observed the closure by removal of four hydraulic lifts from the former
transmission service facility. Based on the field observations and laboratory results, it is ECS's
opinion that a release had occur from the lifts in both locations of the building. Approximately 79
tons of impacted soil was excavated from two separate excavations for off -site disposal. CCI
transported the soil to Earthtec of NC, Inc. in Sanford, North Carolina for disposal. Based on
the analysis of soil samples collected following the soil removal/disposal, EPH range
hydrocarbons remain in the soil at the rear of the building above the NCDEQ Residential
MSCCs. The soil is located approximately 12 to 13 feet below grade.
9.0 RECOMMENDATIONS
ECS recommends that a copy of this report be submitted for review to the NCDEQ, Mooresville
Regional Office. ECS recommends that a Notice of No Future Action (NFA) be issued for the
release upon obtaining a Notice of Residual Petroleum (NRP) restricting land use to
industrial/commercial (no residential use) and restricts groundwater use at the site. ECS

Definitions of Sources
Tank: means the tank that stores the product and is part of the underground storage tank system
Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end -use equipment (Vent, vapor recovery, or fill
lines are excluded.)
Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above
the shear valve)
Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that
connects the submersible turbine pump to the tank
Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor
recovery lines, and fill lines)
Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser)
Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser)
Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken
components, and components that have changed dimension)
Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust)
Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly
Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells)
Unknown: use when the cause has not been determined
