EXECUTIVE SUMMARY
The purpose of this report is to present the results of Phase I Limited Site Assessment (LSA)
activities conducted between August 30, 2017 and September 5, 2017, at the Smith Turf and
Irrigation facility (Site) located at 4359 Golf Acres Drive in Charlotte, Mecklenburg County, North
Carolina (Figure 1). The activities were conducted in accordance with the requirements outlined
in the Notice of Regulatory Requirements (NORR) letter issued by the North Carolina Department
of Environment Quality (NCDEQ) on July 28, 2017. The removal of one 10,000-gallon diesel
underground storage tank (UST), one 270-gallon waste oil UST and closure assessment activities
were conducted by others at the site in October 1993. Laboratory analysis of the closure soil
samples collected from beneath the former used oil tank identified elevated concentrations of
Total Petroleum Hydrocarbons (TPH) Oil and Grease ranging from 1,053 to 2,713 milligrams per
kilogram, (mg/kg). Based on the NCDEQ UST closure guidance at the time and the results of
TPH Oil & Grease analysis, a Site Sensitivity Evaluation (SSE) was completed for the Site. The
SSE established a final TPH clean-up level for the Site of 2,500 mg/kg. Based on the results of
the SSE, no further action was conducted at the Site and a Tank Closure Report was submitted
to the NCDEQ (dated October 29, 1993). In July 2017, following a routine review of the Site status,
the NCDEQ issued a NORR letter requesting an LSA be performed at the Site to gather additional
information to be used in establishing the Site's risk classification.
Smith Holdings, LLC retained Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec
Foster Wheeler) to perform an LSA at the Site to evaluate potential impacts to groundwater and/or
sensitive receptors in the vicinity of the suspected source area. This evaluation included
advancing a soil boring within the former used oil tank excavation area for the purpose of
collecting soil samples as well as installing a monitoring well to collect groundwater samples for
analysis. The well was installed in the approximate area of the former used oil tank excavation pit
(Figure 2).
The soil sample analysis identified chromium concentrations in the three soil samples collected
from the vadose zone that exceeded the NCDEQ, UST Program, Soil -to -Water Maximum Soil
Contaminant Concentration (MSCC) for chromium. The chromium concentration identified in
sample B-1 (13.5-15) exceeded the Residential MSCC for chromium. However, measurement of
the stabilized groundwater elevation suggested that the 13.5 to 15 foot soil sample was collected
from below the water table. The chromium concentrations identified in the three samples are
within the expected range of background chromium concentrations for Mecklenburg County,

North Carolina according to data published by the USGS. The lead and naphthalene
concentrations identified in the soil samples collected did not exceed their respective MSCCs
The analysis of the groundwater sample identified a concentration of MTBE in the groundwater
sample that did not exceed the NC 2L Standard for MTBE. No detectable concentrations of
SVOCs, EPH, or VPH were identified in the three soil samples collected. No detectable chromium,
lead, SVOC, EPH, or VPH concentrations were identified in the groundwater sample collected
from well MW-1. Based on these findings, Amec Foster Wheeler requests that a Notice of No
Further Action be issued by NCDEQ for Incident 11395.

B. SITE HISTORY AND SOURCE CHARACTERISTICS
The Site is comprised of Mecklenburg County Tax Parcel 115-086-21 and encompasses
approximately 8.69 acres. A map showing the topography of the Site is included as Figure 1. At
the time of the LSA activities, the Site was occupied by Smith Turf and Irrigation Company.
On August 4, 1993, SPATCO Environmental (SPATCO) completed a UST-3 Notification of Tank
Closure Form and submitted it to the Mooresville Regional Office of the NCDEQ (then
NCDEHNR). On October 1, 1993, SPATCO excavated and removed one 10,000-gallon diesel
UST and one 270-gallon used oil UST from the Site. No detectable total petroleum hydrocarbon
(TPH) concentrations were identified in the samples collected from beneath the 10,000-gallon
UST and associated product line. Concentrations of TPH Oil & Grease were identified in the two
samples collected from beneath the 270-gallon used oil UST (HB-9 — 2,713 mg/kg and HB-10 —
1,053 mg/kg). Based on the NCDEHNR UST closure guidance at the time and the results of TPH
Oil & Grease analysis, a Site Sensitivity Evaluation (SSE) was completed for the Site. The SSE
established a final TPH clean-up level for the Site of 2,500 mg/kg. Based on the results of the
SSE, no further assessment or cleanup was performed at the Site and a Tank Closure Report
was submitted to the NCDEQ on October 29, 1993. Following a routine review of the Site status,
the NCDEQ issued a NORR letter, dated July 28, 2017 requesting an LSA be performed at the
Site to gather additional information to be used in establishing the Site's risk classification.

D. RECEPTOR INFORMATION
Potential receptors considered as part of the LSA included identification of water -supply wells,
public water supplies, surface waters, wellhead protection areas, subsurface structures, land use,
and property owners and occupants. The following sections provide our results of the receptor
investigation.
1. Water -Supply Wells
Amec Foster Wheeler personnel conducted a potable well search by walking through the
surrounding neighborhood public right-of-way within 500 feet of the source area, and performed
a driving reconnaissance of streets and properties within 1,500 feet. No potable wells were
identified by Amec Foster Wheeler during the well search.
Three water -supply wells were identified via the Mecklenburg County Well Information System
4.0 on-line system. One in-service irrigation well was identified approximately 1,360 feet west-
southwest of the source area at 4425 Golf Acres Drive. One out -of -service irrigation well was
identified approximately 1,415 feet south of the source area at 3335 Jason Avenue. One "ambient"
well was identified approximately 1,500 feet south of the source area at 3335 Jason Avenue. An
ambient well is a well that is routinely monitored by Mecklenburg County Public Health to assess
groundwater quality.
2. Public Water Supplies
Amec Foster Wheeler observed water -meter vaults along the roads while walking within 500 feet
of the Site. Amec Foster Wheeler mailed water -supply well information surveys to the owners of
seven properties surrounding the Site. While there is no restriction on use of water wells in the
county, public water is available to the residences and businesses within 1,500 feet of the
contaminant source areas. Figure 3 is a well survey map showing the area included in the survey.
No drinking water -supply wells were identified within a 1,500 foot radius of the Site. We received
two responses to the well information surveys and the responses indicated the properties were
connected to the public water supply. The responses to the well information surveys and the six
registered mail green cards received to date are included in Appendix A.

F. GEOLOGY AND HYDROGEOLOGY
The following sections describe the regional geologic conditions and the methods employed to
obtain physical data that support our discussion of the local geologic and environmental
conditions.
1. Topographic Conditions
Based on the United States Geologic Survey (USGS) topographic map, the elevation at the Site
ranges from approximately 680 to 700 feet above mean sea level (msl). The land surface elevation
of the area of the former used oil UST is approximately 687 feet msl. Surface drainage patterns
within the Piedmont typically indicate the direction contaminants would be transported by surface
or groundwater. Based on our interpretation of the topographic map and on -site observations,
surface water on the Site would be expected to flow to the west.
2. Site Geology
The Web Soil Survey of Mecklenburg County indicates that soils at the Site are classified as
Mecklenburg fine sandy loam (MeD) and Urban land (Ur). Mecklenburg soils are well drained and
located on broad smooth interstream divides on the uplands. Urban land are areas where the
soils are covered with asphalt, concrete, buildings or other impervious cover and most of the soil
material has been cut, filled, and graded, and the natural characteristics altered or destroyed.
3. Regional Geology
The site is located within the Charlotte Belt of the Piedmont Physiographic Province consisting of
low rounded hills and long rolling northeast to the southwest trending ridges with incised creek
channels. Based on a review of the North Carolina Geologic Map, the site is underlain by
metamorphosed quartz diorite.
Surface and subsurface drainage patterns within the Piedmont typically indicate the direction
contaminants would be transported by surface water or groundwater. The direction and
movement of groundwater through soil is dependent on soil type and the presence of relict
structures and textures of the underlying rock. Fractures, faults, folds and foliation planes affect
the migration of groundwater in rock. Groundwater recharge within the Piedmont region generally
occurs on upland areas. The residual soils and saprolite act as an infiltration medium and reservoir
14

4359 Golf Acres Drive, Charlotte, North Carolina
Amec Foster Wheeler Project: 6228-17-0439
for water to seep into the fractures and joints of the underlying rock. Discharge from the system
occurs at surface water features such as streams and lakes or at the base of slopes.
Since no geologic features were identified on or near the Site, it is reasonable to assume that the
direction of on -surface groundwater flow under static conditions (no pumping interference)
approximates the surface topography of the Site. Groundwater at the site would be expected to
flow to the west toward Taggart Creek.

G. SAMPLING RESULTS
Prior to commencing sampling activities, Amec Foster Wheeler contacted the North Carolina
underground utility location service (One -Call) and a private underground utility locator to mark
buried objects such as pipes, tanks or underground utility lines. The purpose of this effort was to
minimize the potential for probing into underground utilities, tanks or lines buried at the subject
property. Prior to initiating the boring advancement, Amec Foster Wheeler obtained a Subsurface
Investigation Permit (SIP) form Mecklenburg County Health Department, Groundwater and
Wastewater Services. The SIP is included in Appendix B.
On August 30, 2017, Amec Foster Wheeler's drilling subcontractor, Geologic Exploration, Inc.
(Geologic), mobilized to the subject property to advance one soil boring and install one
groundwater monitoring well within the former used oil tank excavation (Figure 2). The boring (B-
1) was advanced using a hollow -stem auger drill rig. Core samples of soil were removed as the
borehole was advanced via a split -spoon sampler to allow for our field representative to collect
soil samples for analysis and to prepare a boring log. The split -spoon samplers were
decontaminated by scrubbing with a Liquinox° wash and rinsed with distilled water between each
sample interval. Analytical samples were collected from boring B-1 from approximately 3.5 to 5
feet below ground surface (bgs) [B-1 (3.5-5)], from approximately 8.5 to 10 feet bgs [B-1 (8.5-10)],
and from approximately 13.5-15 feet bgs [B-1 (13.5-15)]. The soil samples were collected using
dedicated disposable nitrile gloves, placed in laboratory -provided containers, placed in coolers on
ice and delivered under chain -of -custody protocol to Pace Analytical Services, Inc. (Pace) in
Huntersville, North Carolina. The samples were analyzed for Volatile Organic Compounds (VOCs)
by EPA Method 8260, Semi -volatile Organic Compounds (SVOCs) by EPA Method 8270D, VPH
and EPH by the MADEP Method and total chromium and lead by EPA Method 6010. A soil boring
field worksheet is included in Appendix B.
Following the collection of the soil samples, boring B-1 was advanced to a depth which intersected
the groundwater table and a groundwater monitoring well (MW-1) was installed. On the day the
boring was drilled, the depth to groundwater was measured inside the hollow -stem augers at
about 18 feet bgs. Based on this measurement, groundwater monitoring well MW-1 was installed
to an approximate depth of 23 feet bgs. The monitoring well consisted of a two-inch inside
diameter (ID), Schedule 40 polyvinyl chloride (PVC) well casing with the bottom 15-foot section
of the well consisting a manufactured well screen with 0.010-inch machined slots. A bottom plug

was placed on the well screen. A lockable well cap was placed on the top of the riser pipe. The
annular space around the well was filled with filter sand to approximately 2 feet above the top of
the screen. An approximately two -feet -thick seal consisting of bentonite pellets was placed above
the sand pack. The bentonite pellets were hydrated prior to placement of the grout seal. A cement-
bentonite grout seal was placed in the annular space above the bentonite layer. The cement-
bentonite grout seal extended from the top of the bentonite seal to the ground surface. The
monitoring well was completed with a 2 by 2 foot concrete pad and stainless -steel manhole cover.
A well construction record is included in Appendix C. The monitoring well was developed on
August 30, 2017 by Amec Foster Wheeler personnel using a submersible pump until the
groundwater was visibly clear. The development water was discharged on to the ground surface
near the well head.
On September 5, 2017, Amec Foster Wheeler personnel collected a groundwater sample from
monitoring well MW-1. Prior to sample collection, the water level was measured at about 10 feet
below the top of the casing in the well using an electronic water level probe. The purpose of this
measurement was to determine the depth to the water surface from the top of the PVC riser pipe.
The measured water depth was used in conjunction with the total casing depth to determine the
height of the water column and the volume of water in the monitoring well. Following measurement
of the groundwater level, the groundwater sample was collected by low -flow purging techniques,
to the extent possible, in general accordance with the United States Environmental Protection
Agency (USEPA) guidance document "Low Stress (low -flow) Purging and Sampling Procedure
for the Collection of Ground Water Samples from Monitoring Wells", dated July 30, 1996.
During purging, measurements of groundwater field parameters (pH, specific conductivity,
turbidity, temperature, dissolved oxygen and ORP) were collected. Purging of the monitoring well
was considered complete following three consecutive readings of field measurements within 10%
of the previous reading in each well. Following completion of purging, the groundwater sample
was collected from the monitoring well, placed in laboratory -provided containers, placed in a
cooler on ice and delivered under chain -of -custody protocol to Pace. The groundwater sample
was analyzed for VOCs by EPA Method 6200B, SVOCs (Base/Neutrals and Acid Extractables)
by EPA Method 625, VPH and EPH by the MADEP Method and total lead and chromium by EPA
Method 6010. The monitoring well sampling record is included in Appendix D.

The results of the soil laboratory analysis are presented in Table 1 and are summarized as
follows:
Chromium was identified soil sample B-1 (3.5-5) at a concentration of 35.2 mg/kg,
in soil sample B-1 (8.5-10) at a concentration of 24.2 mg/kg, and in soil sample B-
1 (13.5-15) at a concentration of 55.5 mg/kg. However, the measurement of the
stabilized groundwater level in well MW-1 suggested that the 13.5 to 15-foot soil
sampled was collected from below the water table. These concentrations
exceeded the NCDEQ, UST Program, Soil -to -Water Maximum Soil Contaminant
Concentration (MSCC) for chromium of 5.4 mg/kg. However, the concentrations
identified are within the expected range of background chromium concentrations
for Mecklenburg County, North Carolina (70 mg/kg) according to data published
by the US Geological Survey (USGS)'.
Lead was identified soil sample B-1 (3.5-5) at a concentration of 3.3 mg/kg, in soil
sample B-1 (8.5-10) at a concentration of 4.5 mg/kg, and in soil sample B-1 (13.5-
15) at a concentration of 9.3 mg/kg. These concentrations did not exceed the
MSCCs for lead.
Naphthalene was identified in soil sample B-1 (3.5-5) at a concentration of 22.5
micrograms per kilogram (pg/kg). This concentration did not exceed the MSCCs
for naphthalene of 160 pg/kg. No other detectable VOC concentrations were
identified in the three soil samples collected.
No detectable SVOC, EPH, or VPH concentrations were identified in the three soil
samples collected.
The results of the groundwater laboratory analysis are presented in Table 2 and are
summarized as follows:
Methyl-tert- butyl ether (MTBE) was identified in the groundwater sample collected
from well MW-1 at a concentration of 0.76 micrograms per liter (pg/L). This
concentration did not exceed the North Carolina Administrative Code, Title 15A,
Subchapter 2L, Section .0202, Groundwater Quality Standard (NC 2L Standard)
for MTBE of 20 pg/L. No other detectable VOC concentrations were identified in
the groundwater sample collected from well MW-1.
No detectable chromium, lead, SVOC, EPH, or VPH concentrations were identified
in the groundwater sample collected from well MW-1.
The soil and groundwater analytical reports and chain -of -custody forms are included in Appendix
E.

H. CONCLUSIONS
Based on the results of the LSA activities, we offer the following conclusions:
No free product was identified in well MW-1.
Properties to the north, west and south are occupied by commercial office/light
industrial buildings and properties to the east are occupied by light industrial and
residential buildings. See Figure 4 for a map of zoning in the area. Given the
current use of properties in this area, the site should be assigned an
industrial/commercial land use classification.
Amec Foster Wheeler personnel conducted a potable well search by walking
through the surrounding neighborhood public right-of-way within 500 feet of the
source area (Figure 3), and performed a driving reconnaissance of streets and
properties within 1,500 feet. No potable wells were identified by Amec Foster
Wheeler during the well search. Three water -supply wells were identified via the
Mecklenburg County Well Information System 4.0 on-line system. One in-service
irrigation well was identified approximately 1,360 feet west-southwest of the source
area at 4425 Golf Acres Drive. One out -of -service irrigation well was identified
approximately 1,415 feet south of the source area at 3335 Jason Avenue. One
"ambient" well was identified approximately 1,500 feet south of the source area at
3335 Jason Avenue. An ambient well is a well that is routinely monitored by
Mecklenburg County Public Health to assess groundwater quality.
Amec Foster Wheeler mailed water -supply well information surveys to the owners
of seven properties surrounding to the Site. We received two responses the well
information surveys and the responses indicated the properties were connected to
the public water supply.
Taggart Creek is located approximately 850 feet to the west of the source area of
the release.
The chromium concentrations identified in the three soil samples collected
exceeded the Soil -to -Water MSCC for chromium. However, the concentrations
identified in the three soil samples are within the expected range of background
chromium concentrations for Mecklenburg County, North Carolina according to
data published by the USGS.
The lead and naphthalene concentrations identified in the soil samples collected
did not exceed their respective MSCCs.
The MTBE concentration identified in the groundwater sample did not exceed the
NC 2L Standard for MTBE.
No detectable SVOC, EPH, or VPH concentrations were identified in the three soil
samples collected. No detectable chromium, lead, SVOC, EPH, or VPH
