Brownfields Project No. 21024-17-060
H&H Project No. LEN-004

1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this Brownfields Assessment Report for the Block 42
Brownfields property (Brownfields Project No. 21024-17-060) located at 500 N. College Street in
Charlotte, Mecklenburg County, North Carolina (Site). The Site consists of approximately 3.62 acres
of land bounded by N. College Street to the northwest, the Lynx light rail line to the southeast, E. 9th
Street to the northeast, and E. 8th Street to the southwest. The Site is currently developed with a vacant
commercial warehouse building most recently occupied by an artist cooperative located at 514 North
College Street, and a vacant office building located at 228 East 9th Street. Remaining portions of the
Site consist of an asphalt-paved surface lot utilized by a pay-for-parking business. A Site location
map is provided as Figure 1, and a Site and surrounding area map is provided as Figure 2.

As early as the 1880s, the eastern portion of the Site was developed with a planing mill and the
southern portions of the Site were developed with residences. By the 1910s, construction of additional
structures associated with the planing mill had been completed in the east-central and eastern portions
of the Site with remaining portions of the Site developed for residential use. By the 1920s, the planing
mill structures and residences located in the southern portion of the Site had been razed and a Norfolk
Southern railroad spur was constructed across the eastern and southern portions of the Site.

In the early 1950s, the western portions of the Site were developed with the Southern Bearings and
Parts Company facility which operated until the 1970s. In addition to the Southern Bearing and Parts
Company facility, the northern, eastern, and southern portions of the Site were developed with
warehouse buildings in the late 1940s and early 1950s. Uses of the Site warehouse buildings included
restaurant equipment distribution, beer distribution, and paint distribution from the late 1950s until
the 1990s. These buildings have also contained various retail stores and restaurants over time. The

Southern Parts and Bearings Company facility was demolished in 2005 and the western portions of
the Site were paved with the current parking lot.

1.1 Background

H&H completed Phase I Environmental Site Assessment (ESA) activities at the Site in September
2016. Results of the Phase I ESA and subsequent discussions with the North Carolina Department of
Environmental Quality (DEQ) identified the following potential environmental concerns in
connection with the Site:

 The eastern portion of the Site was developed as early as the 1880s with a planing mill.
Portions of the planing mill were used for painting, glazing, and finishing until the 1920s. In
addition, the southern and western portions of the Site were formerly occupied by Southern
Parts and Bearings Company, a metal parts wholesale distributor, from the 1950s until the
1970s. Southern Parts and Bearings Company operations included a machine shop,
warehouses, and offices. The potential for impact associated with historical planing mill and
Southern Parts and Bearing Company operations was identified as a potential environmental
concern.

 A previous Phase I ESA completed in 2002 indicated that the building located at 228 East 9th
Street had vent pipes on the northeastern exterior wall which were potentially associated with
underground storage tanks (USTs). The vent pipes were not observed by H&H personnel
during our Site reconnaissance and no records pertaining to current or former USTs were
identified in the regulatory databases researched. The potential for impacts associated with
the possible UST(s) located east of the 228 E. 9th Street Site building was identified as a
potential environmental concern.

 H&H identified a possible oil/water separator (OWS) located to the southwest of the 514
North College Street building. The OWS is reported to be currently out of service; however,
its former use could not be confirmed. The potential for impact associated with the possible
OWS was identified as a potential environmental concern.

 A gasoline underground storage tank (UST) is depicted near the southern Site boundary on a
1950 Sanborn map. The potential for impact to the Site from the possible orphan UST in the
southern portion of the Site was considered a potential environmental concern.

The Site received eligibility into the DEQ Brownfields Program via a Letter of Eligibility dated June
5, 2017. The Prospective Developer (PD), LMC Block 42 Holdings, LLC and LMV Block 42
Holdings, LP subsequently elected to participate in the Brownfields Program Redevelopment Now
Pilot option. As part of this process, a kick-off/data gap meeting with the PD, counsel for the PD,
DEQ Brownfields personnel, and H&H was held at the Site on July 11, 2017 to discuss prior Site
history, proposed redevelopment plans, data gaps, and the proposed schedule for completing the
Brownfields Agreement. To address the data gaps, H&H submitted a work plan for additional
assessment activities and a revised work plan based upon DEQ comments. The Brownfields
Assessment Work Plan – Revision 1 (Work Plan) dated September 11, 2017 subsequently received
DEQ Brownfields approval in a letter dated September 12, 2017.

A summary of Brownfields assessment activities conducted to evaluate the potential for impact in
areas of concern identified at the Site is provided in the following sections.

2.0 Brownfields Assessment Activities

In September 2017, H&H completed soil and groundwater assessment activities at the Block 42
Brownfields property to evaluate potential impacts associated with the areas of concern identified
during Phase I ESA activities, and to assist in management of Site media during future
redevelopment activities. In addition to soil and groundwater assessment activities, H&H
completed receptor survey activities at the Site and nearby area in September 2017.

Based on results of the September 2017 groundwater assessment activities and subsequent
conversations with DEQ Brownfields personnel, H&H returned to the Site in November 2017 to
collect soil vapor samples within the footprint of the proposed Site buildings to evaluate the
potential for vapor intrusion and to establish a baseline list of compounds for evaluation of post-
construction indoor air quality inside the proposed Site buildings. Brownfields assessment soil,
groundwater, and soil vapor sample locations are depicted on Figure 3.

The assessment activities were conducted in general accordance with the DEQ Inactive Hazardous
Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated October 2015 and most recent
versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem
Support (SESD) Field Branches Quality System and Technical Procedures guidance. The results of
the soil assessment, groundwater assessment and soil vapor assessment are provided in Sections 3.0,
4.0, and 5.0, respectively, the receptor survey results are provided in Section 6.0, and summary and
conclusions based on the assessment activities are provided in Section 7.0.

3.0 Soil Assessment Activities

On September 20 and 21, 2017, H&H contracted with Innovative Environmental Technologies,
Inc. (IET) to collect soil samples in areas of concern based on historical uses at the Site and the
proposed redevelopment plan. H&H also collected one background soil sample from a location in
the northern portion of the Site that does not appear to have been affected by historical uses to
evaluate for naturally occurring concentrations of metals in Site soil.

Prior to conducting field activities, H&H contacted North Carolina 811, the public utility locator,
to mark subsurface utilities located on the Site. H&H also contracted with a private utility locator
to screen proposed sample locations for subgrade utilities that may not be marked by the public
locator. Additionally, soil boring locations were hand cleared to approximately 5 feet (ft) below
the ground surface (bgs) prior to use of mechanical drilling equipment to further screen the boring
locations for the presence of subsurface utilities. In accordance with Mecklenburg County rules,
H&H obtained a Subsurface Investigation Permit (SIP No. 70002456) from Mecklenburg County
prior to beginning groundwater assessment activities.

The private utility locator also utilized ground penetrating radar (GPR) and
electromagneticgeophysical survey techniques to evaluate the potential for USTs in the vicinity of
the 228 East 9th Street building and a potential UST near the southern Site boundary depicted on a
1950 Sanborn map. Interpretation of geophysical survey results did not identify subsurface
anomalies consistent with USTs at the Site.

Soil sampling activities and results are described in the following sections.

3.1 Soil Sampling Methodologies

H&H advanced ten (10) soil borings and collected eight (8) soil samples for laboratory analysis to
evaluate the potential for impact in areas of concern identified at the Site and in areas at the Site
that will be disturbed during grading associated with redevelopment activities. Soil boring

locations (denoted by SB nomenclature) are depicted on Figure 3, and were advanced in the
following locations:
 one background soil boring was advanced in the northern portion of the Site to establish
Site-specific background concentrations of metals (SB-1);
 one soil boring was advanced in the southeastern portion of the Site downgradient of the
former bearing facility and in the vicinity of the former planing mill glazing building
(SB-2);
 one soil boring was advanced in the southern portion of the Site downgradient of the former
bearing facility and in the vicinity of the former glazing and finishing building (SB-3);
 one soil boring was advanced in the area of the former machine shop for the bearing facility
in the western portion of the Site (SB-4);
 one soil boring was advanced in the vicinity of the potential UST identified on the 1950
Sanborn map in the southern portion of the property (SB-5);
 soil borings were advanced adjacent to the influent and effluent piping of the potential oil-
water separator (SB-6 and SB-6A);
 one soil boring was advanced near the loading dock on the southeastern side of the 514 N.
College Street building (SB-7);
 one soil boring was advanced in the central portion of the Site where up to approximately
4 ft of cut is planned as part of redevelopment activities (SB-8); and
 one soil boring was advanced in the vicinity of the potential UST basin identified during
previous 2002 Phase I ESA activities conducted by others and in the area of the historical
planing mill in the eastern portion of the Site (SB-9).
As part of soil assessment activities, IET utilized a track-mounted direct push technology (DPT)
drill rig to advance soil borings to depths ranging from approximately 11 – 15 ft bgs in the locations
outlined above. Continuous soil samples were collected from the borings using acetate lined
macrocore sleeves. The soil samples were logged for lithologic description and screened using
visual and olfactory methods for obvious evidence of staining, unusual odors, and for the presence
of volatile organic vapors using a calibrated photoionization detector (PID). There were no
obvious indications of potential impact in Site soil based on field screening results. Therefore, soil

7
S:\AAA-Master Projects\Lennar (LEN)\Block 42 (LEN-004)\Brownfields Assessment Report\final to client\client
comments\Active_98388809_1_draft Brownfields Assessment Report_Block 42 (BPN 2102.._.docx
samples were collected from shallow soil (0-2 or 2-4 ft bgs) with the exception of the SB-5 and
SB-6 soil borings as discussed below.

Field screening results did not indicate obvious evidence of impact in the SB-5 soil boring
advanced in the vicinity of the UST depicted in the southern portion of the Site on the 1950
Sanborn map. Additionally, interpretation of geophysical survey results did not identify anomalies
consistent with a UST in the southern portion of the Site. Therefore, in accordance with the
approved Work Plan, no soil sample was collected for laboratory analysis from the SB-5 soil
boring.

The SB-6 and SB-6A soil borings were advanced adjacent to the influent and effluent sides of the
potential oil-water separator identified on the southwestern side of the Site building located at 514
N. College Street. Results of field screening did not identify obvious evidence of impacts in soil
samples. Therefore, a soil sample was collected for laboratory analysis from the depth interval in
the SB-6 soil boing interpreted to be below the base of the oil-water separator system (7-9 ft bgs).
No soil sample was collected for laboratory analysis from boring SB-6A. Boring logs, including
lithologic descriptions and field screening results are provided in Appendix A.

Soil samples selected for laboratory analysis were placed directly into dedicated laboratory-
supplied sample containers, labeled with the sample identification, date, and requested analysis,
and placed in a laboratory-supplied sample cooler with ice. The samples were delivered to Con-
Test Analytical Laboratory (Con-Test), a North Carolina certified laboratory, under standard chain
of custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260B,
semi-VOCs (SVOCs) by EPA Method 8270D, and Resource Conservation and Recovery Act
(RCRA) metals plus hexavalent chromium by EPA Methods 6020A/7471B/7196A. In addition,
soil samples collected from the background sample location (SB-1) and the sample locations near and
associated with planing mill operations (SB-2, SB-3, SB-8, and SB-9) were submitted for analysis of
copper and zinc by EPA Method 6020 per DEQ Brownfields request. The Con-Test laboratory
analytical report and chain of custody record are provided in Appendix B.

In addition to the analyses above, the soil sample collected from soil boring SB-4 (former machine
shop for the Southern Parts and Bearing facility) was shipped under standard chain of custody
protocols to TestAmerica Laboratories, Inc (TestAmerica) for analysis of polychlorinated biphenyls
(PCBs) by EPA Method 8082A. H&H also submitted an additional SB-4 soil sample for analysis of
PCB congeners by EPA Method 1668A, and requested that TestAmerica hold the sample pending
analytical results for the sample analyzed for PCBs by EPA Method 8082A. The TestAmerica
laboratory analytical report and chain of custody record are provided in Appendix B.

For quality assurance/quality control purposes, a duplicate soil sample was collected from the SB-9
parent soil sample and submitted to Con-Test for analysis of VOCs by EPA Method 8260B, SVOCs
by EPA Method 8270D, and RCRA metals plus hexavalent chromium, copper, and zinc by EPA
Methods 6020A/7471B/7196A.

Following completion of soil sampling, soil borings SB-1 through SB-4 were converted to
temporary groundwater monitoring wells and the SB-8 soil boring was converted to a piezometer
to obtain additional information associated with groundwater elevations at the request of the PD.
Remaining soil borings were properly abandoned and the surfaces were repaired similar to pre-
drilling conditions. Additionally, the soil sample locations were estimated using a Trimble GeoXT
hand-held global positioning system (GPS) unit.

3.2 Soil Sample Analytical Results

A tabular summary of soil sample analytical results is presented in Table 1. The laboratory
analytical results were compared to the DEQ IHSB Unrestricted Use and Industrial/Commercial
Preliminary Soil Remediation Goals (PSRGs) dated October 2017. In addition to the PSRGs,
metals results were compared to Site-specific and published concentrations for naturally occurring
metals in North Carolina soil.

Laboratory analytical results indicate that a low level of acetone was detected in the SB-9 (0.32 J
mg/kg) soil sample collected in the eastern portion of the Site at a concertation above the laboratory
method detection limit, but well below the Unrestricted Use PSRG of 12,000 mg/kg. No other

comments\Active_98388809_1_draft Brownfields Assessment Report_Block 42 (BPN 2102.._.docx
VOCs were detected above the laboratory method detection limits in other soil samples collected
at the Site.

Results of SVOC analysis indicate that several polynuclear aromatic hydrocarbons (PAHs) were
detected above the laboratory method detection limit in the SB-9 soil sample from the eastern
portion of the Site. Benzo(a)pyrene (0.33 mg/kg) was detected at a concentration exceeding its
Unrestricted Use PSRG of 0.11 mg/kg. No other SVOCs were detected at concentrations
exceeding the Unrestricted Use PSRGs, and no SVOCs were detected at concentrations exceeding
Industrial/Commercial PSRGs. Soil sample locations with benzo(a)pyrene concentrations are shown
on Figure 4.

Soil sample SB-4 collected in the location of the former bearing facility machine shop was
submitted for laboratory analysis of PCBs by EPA Method 8082A. Laboratory analytical results
indicate that no PCBs were detected above the laboratory method detection limits in the soil
sample. Therefore, the additional SB-4 soil sample was not released for PCB congener analysis.

As expected, several metals were detected at concentrations above the method detection limits in
each soil sample. The arsenic concentration detected in the SB-9 (5.3 mg/kg) soil sample is
elevated relative to other arsenic concentrations detected in Site soil samples (range from 0.98
mg/kg to 2.0 mg/kg). Additionally, the SB-9 arsenic detection slightly exceeds the published mean
concentration for naturally occurring arsenic in North Carolina soil. Arsenic levels in the SB-9
soil sample exceed the Unrestricted Use PSRG (0.68 mg/kg) and the Industrial/Commercial PSRG
(3.0 mg/kg) and does not appear to be consistent with naturally occurring levels. The remaining
detected metals concentrations are consistent with Site-specific and regional background
concentrations for naturally occurring metals.

4.0 Groundwater Assessment Activities

On September 20, 2017, H&H and IET installed four (4) temporary groundwater monitoring wells
(TMW-1 through TMW-4). Groundwater samples were collected for laboratory analysis from
each temporary monitoring well to evaluate the potential for groundwater impacts at the Site.
Locations of the temporary groundwater monitoring wells (denoted by TMW nomenclature) are
depicted on Figure 3 and were installed in the following locations:
 upgradient location in the northern portion of the Site to evaluate background groundwater
quality (TMW-1);
 downgradient of the former bearing facility and in the area of the former planing mill
glazing building (TMW-2);
 downgradient of the former bearing facility and in the area of a former glazing and finishing
building (TMW-3); and
 in the area of the former machine shop for the bearing facility in the southwestern portion
of the Site (TMW-4).

Details of the groundwater sampling activities and results are provided in the following sections.

4.1 Groundwater Sampling Methodology

The temporary monitoring well borings were advanced using a track-mounted DPT drill rig to
advance soil borings utilizing small diameter hollow-stem augers until sufficient groundwater was
encountered. H&H described soil samples collected from the hollow stem auger cuttings for
lithologic description and field screened the samples for the presence of obvious staining, unusual
odors, and volatile organic vapors using a calibrated PID. H&H did not observe obvious evidence of
impact in drill cuttings based on field screening results.

Temporary monitoring wells were constructed of 2-inch diameter PVC with 15 ft of pre-pack well
screen set to bracket the water table and 2-inch diameter PVC well casing to the ground surface. A
filter sand pack was installed from the bottom of each temporary well boring to approximately 2 ft
above the pre-pack well screen, and a hydrated bentonite seal was then installed above the filter sand
pack. Temporary monitoring well boring logs and construction details are provided in Appendix A.

comments\Active_98388809_1_draft Brownfields Assessment Report_Block 42 (BPN 2102.._.docx
Upon completion of temporary monitoring well installation activities, the wells were allowed to
equilibrate to static conditions and a decontaminated electronic water level indicator was used to
measure the depth to the water table relative to the ground surface and the tops of the well casings.
Depths to the equilibrated water table relative to the ground surface ranged from approximately 11.7
ft bgs (TMW-1) in the northern portion of the Site to approximately 16.2 ft bgs (TMW-3) in the
southern portion of the Site. To obtain additional information associated with groundwater elevations
at the Site for redevelopment purposes and to estimate groundwater flow direction across the Site,
H&H surveyed the tops of the temporary well and piezometer casings relative to previously surveyed
benchmarks at the Site. Based on groundwater elevation data, groundwater flow direction at the Site
is generally toward the southeast. A summary of well construction information, depths to
groundwater, and groundwater elevation data is provided as Table 2. A groundwater gradient map is
provided as Figure 5.

Upon completion of groundwater elevation measurement activities, each temporary well was then
developed by removing a minimum of 3 to 5 well volumes until field parameters stabilized (pH ± 0.1
SU and conductivity varied no more than 5%). After development, a groundwater sample was
collected from each temporary monitoring well utilizing low flow/low stress purging techniques using
a peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing was placed
in the approximate mid-portion of the screened interval of the well and groundwater was removed at
a rate no greater than 200 milliliters per minute. H&H utilized a water quality meter to collect
measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and
specific conductivity during the purging process. Purging was considered complete when the
parameters had stabilized (pH ± 0.1 SU, conductivity varied no more than 5%, and turbidity was less
than 10 Nephelometric Turbidity Units or NTUs). Groundwater sampling forms completed by H&H
sampling personnel are provided in Appendix C.

Once groundwater parameters stabilized, the groundwater samples were collected directly into
laboratory supplied sample containers using the “soda straw” method to minimize volatile loss
through the peristaltic pump head. The sample containers were labeled with the sample identification,
date, and requested analysis, and placed in a laboratory supplied cooler and iced. The samples were

delivered to Con-Test under standard chain of custody protocols for analysis of VOCs by EPA
Method 8260A, SVOCs by EPA Method 8270D, and RCRA metals by EPA Method 6020A/7470A.

Following sample collection, the temporary monitoring wells were properly abandoned and the
surfaces were repaired similar to pre-drilling conditions. Each monitoring well location was estimated
using the GPS unit and the investigation derived waste was thin-spread on-Site.

4.2 Groundwater Sample Analytical Results

A tabular summary of the analytical results for groundwater samples collected from the four
temporary monitoring wells is presented in Table 3. Groundwater data were compared to the DEQ
15A NCAC 02L .0202 Groundwater Standards (2L Standards) and the DEQ Division of Waste
Management (DWM) Residential and Non-Residential Groundwater Vapor Intrusion Screening
Levels (GWSLs) dated October 2017.

Laboratory analytical results indicate that low levels of several VOCs were detected at concentrations
above the laboratory method detection limits in the four groundwater samples collected at the Site.
Trichloroethene (TCE) was detected at concentrations exceeding the 2L Standard of 3 µg/L in
groundwater samples TMW-3 (510 µg/L) and TMW-4 (59 µg/L) in the western and southwestern
portion of the Site in the area of the former bearing facility. The TCE concentrations also exceed the
Residential GWSL (1 µg/L) and Non-Residential GWSL (4.4 µg/L). No other VOCs were detected
above the 2L Standards or the GWSLs in Site groundwater. Groundwater sample locations with TCE
concentrations are shown on Figure 4.

Laboratory analytical results indicate that no SVOCs were detected at concentrations above the
laboratory method detection limits in groundwater samples collected at the Site.

Results of the groundwater samples submitted for metals analysis indicate that low levels of several
metals including arsenic (up to 1.1 µg/L), barium (up to 130 µg/L), chromium (2.3 µg/L), and lead
(0.71 J µg/L) were detected at concentrations above the laboratory method detection limits, but below
the DEQ 2L Standards.

5.0 Soil Gas Assessment

Because TCE was detected in Site groundwater samples at concentrations exceeding the DEQ
DWM Residential and Non-Residential GWSLs, H&H contacted DEQ Brownfields to discuss soil
gas assessment activities in accordance with the approved Work Plan. In an email dated November
9, 2017, DEQ Brownfields provided approval to collect four (4) soil gas samples (SG-1 through
SG-4) within the footprints of the proposed Site buildings to evaluate the potential for structural
vapor intrusion and establish a baseline compound list for evaluation of indoor air quality in future
structures constructed at the Site. Soil gas sample locations (denoted by SG nomenclature) are
depicted on Figure 3.

Details of the soil gas sampling activities and results are provided in the following sections.

5.1 Soil Gas Sample Methodology

On November 15th and 16th, 2017, H&H contracted with Environmental Drilling and Probing
Services (EDPS) to utilize decontaminated stainless steel hand augers and a track-mounted
Geoprobe® 7822DT DPT drill rig to advance soil borings to depths ranging from approximately 5
to 11 ft bgs for the installation of temporary soil gas monitoring points. Very moist soil conditions
from apparent perched water were observed in the SG-2 soil boring advanced in the eastern portion
of the Site. H&H made several attempts to advance deeper borings in the eastern portion of the
Site for installation of a soil gas monitoring point, but moist conditions were encountered in each
attempt. After several attempts to install a deeper soil gas monitoring point, H&H contacted DEQ
Brownfields personnel to discuss installing a shallower soil gas monitoring point in the eastern
portion of the Site. Based on conversations with Ms. Joselyn Harriger of the DEQ Brownfields
Program, the SG-2 soil gas monitoring point was installed to 5 ft bgs.

Continuous soil samples were collected from each boring using acetate lined macrocore sleeves.
Soil samples were described for lithologic purposes and inspected for the presence of staining and
odors, and field screened for the presence of volatile organic vapors with a calibrated PID. No
obvious evidence of impacts was observed in the soil gas borings based on field screening results.

comments\Active_98388809_1_draft Brownfields Assessment Report_Block 42 (BPN 2102.._.docx
A six-inch stainless steel vapor implant screen point fitted with ¼-inch diameter Teflon® tubing
was placed at the bottom of each boring. Filter sand was placed from the base of the boring to
approximately six inches above the top of the vapor implant screen. The sampling points were
completed by placing hydrated bentonite from the top of the filter sand to the ground surface. Soil
gas monitoring point boring logs and construction details are provided in Appendix A.

Prior to sampling, a leak check was conducted at each vapor monitoring point sample location by
constructing a shroud around the sampling point and flooding the air within the shroud with helium
gas. Helium concentrations inside the shroud were measured using a helium gas detector and were
maintained at concentrations of approximately 90%. Using a syringe and three-way valve, the
Teflon tubing and surrounding sand pack were purged of approximately three volumes. Following
purging, a sample was collected from the sample tubing outside the shroud and analyzed using the
helium gas detector to ensure that helium concentrations were less than 10% of the helium
concentrations measured within the shroud. All sample points passed the leak check criteria.

Following a successful leak check, a laboratory-supplied 6-Liter Summa canister with a flow
regulator was connected to the sample tubing at each sampling point using a brass nut and ferrule
assembly to form an air-tight seal. The flow regulator was pre-set by the laboratory to regulate the
vapor intake rate to approximately 6-liters per hour. Once the sample train was assembled, the
intake valve on the canister was fully opened to begin collection of the soil gas sample. Vacuum
readings on the Summa canister were recorded prior to and following the one-hour sampling period
to ensure adequate sample volume was collected.

After sample collection, the Summa canister’s valve was closed, and the regulator was
disconnected from the canister. The canisters were placed in laboratory supplied shipping
containers, properly labeled and shipped under standard chain-of-custody protocols to Con-Test
for analysis of VOCs by EPA Method TO-15.

Upon completion of sampling activities, each soil gas monitoring point was properly abandoned
and the surfaces were repaired similar to pre-drilling conditions. Each soil gas monitoring point
location was estimated using the hand-held GPS unit.

5.2 Soil Gas Sample Analytical Results

The soil gas analytical results are summarized in Table 4. The laboratory analytical report is
provided in Appendix B. Soil gas sample laboratory analytical results were compared to DEQ
DWM Residential and Non-Residential Sub-Slab and Exterior Soil Gas Vapor Intrusion Screening
Levels (SGSLs) (October 2017).

Laboratory analytical results indicate that several VOCs were detected above laboratory method
detection limits in each soil gas sample. Based on conversations with DEQ Brownfields, the VOCs
detected above laboratory method detection limits in soil gas will constitute the target list of
compounds of concern for evaluation of indoor air quality in future structures at the Site (Table 4).

TCE was detected at concentrations exceeding the DEQ DWM Residential SGSL of 14 µg/m3 and
the Non-Residential SGSL of 180 µg/m3 in soil gas samples SG-3 (1,100 µg/m3) and SG-4 (220
µg/m3). Soil gas sample SG-3 was collected in the vicinity of groundwater sample TMW-3 (510
µg/L) where TCE was detected above the DEQ DWM Residential and Non-Residential GWSLs,
and soil gas sample SG-4 was collected in the vicinity of groundwater sample TMW-4 (59 µg/L)
where TCE was detected at concentrations exceeding the Residential and Non-Residential GWSLs
(Figure 4). TCE was not detected above the laboratory method detection limits in soil gas samples
SG-1 and SG-2 collected in the eastern and northern portions of the Site, respectively. No other
VOCs were detected above the Residential or Non-Residential SGSLs in soil gas samples collected
at the Site.

6.0 Receptor Survey Activities

On September 22, 2017, H&H performed receptor survey activities at the Site and in the nearby area.
The receptor survey included an intensive pedestrian and vehicular survey to obtain information about
land use, water supply, basements, underground utilities, drains, and surface water bodies located
within a 1,500 foot (ft) radius of the Site in accordance with the DEQ Brownfields approved Work
Plan. H&H also utilized the online Mecklenburg County Groundwater & Wastewater Services
(GWS) Well Information System map to identify potential potable water supply wells located within
a 1,500 ft radius of the Site. In addition, H&H identified land use and zoning in the area of the Site
and the locations of main underground utilities. A discussion of the receptor survey activities is
provided in the following sections.

Zoning
The subject Site is zoned Uptown Mixed-Use District with optional provisions (UMUD-O). The Site
and properties located adjacent to the north, east, south, and west comprise an approximately 10.9-
acre rezoning initiative which received approval from the City of Charlotte on November 15, 2010.
The properties included UMUD-O rezoning initiative include the areas of the First Ward in uptown
Charlotte generally surrounded by N. College Street, E. 9th Street, N. Brevard Street, and E. 7th Street.

Municipal Water Availability
Municipal water supplied by Charlotte Water is available to the Site and surrounding area. H&H did
not identify sources of public drinking water within 1,500 ft of the Site based on the DEQ Source
Water Assessment Program’s geographic information system map. The City of Charlotte and
Mecklenburg County obtain their water from Lake Norman and Mountain Island Lake which are
located approximately 10 miles northwest of the Site at Mountain Island Lake’s closest point.
Additionally, H&H observed municipal water meters for the Site and surrounding properties.

Water Supply Wells
H&H conducted a pedestrian and vehicular survey of properties within a 1,500 ft radius of the Site to
identify potential water supply wells. H&H also utilized the online Mecklenburg County
Groundwater and Wastewater Services (GWS) Well Information System database map to identify

comments\Active_98388809_1_draft Brownfields Assessment Report_Block 42 (BPN 2102.._.docx
potential potable water supply wells located within a 1,500 ft radius of the Site. No public or private
water supply wells were identified during pedestrian and vehicular survey activities or on the GWS
database map.

Surface Water Bodies
No surface water bodies were identified on the Site or adjacent properties. An unnamed tributary of
Little Sugar Creek is located approximately 700 ft southeast of the Site. Based on the DEQ
classification system, Little Sugar Creek is a Class C surface water body. A Class C surface water
body is defined as “waters protected for uses such as secondary recreation, fishing, wildlife, fish
consumption, aquatic life including propagation, survival and maintenance of biological integrity, and
agriculture. Secondary recreation includes wading, boating, and other uses involving human body
contact with water where such activities take place in an infrequent, unorganized, or incidental
manner”. Little Sugar Creek flows south through Mecklenburg County and discharges into Sugar
Creek in South Carolina approximately 10 miles south-southwest of the Site.

Subsurface Structures
H&H conducted a visual reconnaissance in the Site area to identify potential subsurface structures
within 1,000 ft of the subject Site. H&H observed evidence of subsurface utilities including sanitary
sewer, storm sewer, municipal water, natural gas, communication, and/or electrical on and adjacent
to the subject Site. H&H also observed a potential basement in the northern portion of the Tryon
House apartment building located adjacent to the northwest across N. College Street at 508 N. Tryon
Street.

7.0 Summary and Conclusions

H&H has completed Brownfields assessment activities on the Block 42 Brownfields property located
at 500 N. College Street in Charlotte, North Carolina. The assessment activities were conducted in
accordance with the DEQ Brownfields approved Work Plan dated September 11, 2017 and
subsequent discussions with DEQ Brownfields personnel. Assessment activities included soil,
groundwater, and soil vapor sampling activities to evaluate subsurface conditions for potential
impacts associated with historical Site use and assist in management of Site media during proposed
redevelopment activities. In addition to soil, groundwater and soil vapor assessment activities, a
receptor survey was completed to obtain information about land use, water supply, basements,
underground utilities, drains, and surface water bodies located in the vicinity of the Site. A summary
of the Brownfields assessment results is provided below.

 H&H collected eight (8) soil samples at the Site for laboratory analysis. Laboratory
analytical results indicate that a low level of benzo(a)pyrene (0.33 mg/kg) was detected
above the Unrestricted Use PSRG in the shallow soil sample (SB-9) collected in the
eastern portion of the Site near E. 9th Street. In addition to benzo(a)pyrene, arsenic was
detected in the SB-9 (5.3 mg/kg) soil sample at a concentration above Site-specific and
published background levels. The arsenic detection in the SB-9 soil sample exceeds the
Unrestricted Use PSRG (0.68 mg/kg) and the Industrial/Commercial PSRG (3.0 mg/kg)
and does not appear to be consistent with naturally occurring levels. The remaining
detected metals concentrations are consistent with Site-specific and regional background
concentrations for naturally occurring metals. No VOCs, PCBs, and no other SVOCs
were detected at concentrations above the Unrestricted Use PSRGs in soil samples
collected at the Site.

 H&H collected four (4) groundwater samples at the Site for laboratory analysis.
Laboratory analytical results indicate that TCE was detected at concentrations exceeding
the 2L Standard (3.0 µg/L) and the Residential (1.0 µg/L) and Non-Residential (4.4 µg/L)
vapor intrusion GWSLs in groundwater samples collected from temporary groundwater
monitoring wells TMW-3 (510 µg/L) and TMW-4 (59 µg/L). Temporary wells TMW-3

and TMW-4 were installed in the southern and southwestern portions of the Site,
respectively to evaluate for the presence of impacts associated with former Southern
Bearing & Parts Company operations. No other compounds were detected at
concentrations exceeding 2L Standards or GWSLs in the TMW-3 and TMW-4
groundwater samples. No other compounds were detected at concentrations exceeding
DEQ groundwater screening criteria in samples collected from other areas at the Site.

 Based on groundwater sample analytical results, H&H collected four (4) soil gas samples
for laboratory analysis of VOCs in accordance with the approved Work Plan and
subsequent conversations with DEQ Brownfields personnel. The soil gas samples were
collected within the footprint of the proposed buildings to establish a baseline compound
list for evaluation of post-construction indoor air quality upon completion of
redevelopment activities. Laboratory analytical results indicate that TCE was detected at
concentrations exceeding the DWM Residential (14 µg/m3) and Non-Residential (180
µg/m3) SGSLs in soil gas samples SG-3 (1,100 µg/m3) and SG-4 (220 µg/m3) which were
collected in the southern and southwestern portion of the Site in the vicinity of TCE impacts
identified in groundwater. No other compounds were detected above the SGSLs in the SG-
3 and SG-4 soil gas samples. In addition, no compounds were detected above the SGSLs
in soil gas samples collected in other portions of the Site, which is consistent with results
of soil and groundwater assessment activities completed at the Site.

In summary, low level PAH and arsenic impacts have been identified in shallow soil in the eastern
portion of the Site near E. 9th Street. Soil impacts were not identified in other areas of the Site. Based
on results of soil assessment activities completed at the Site, additional soil assessment is not
warranted and soil disturbed during future redevelopment activities can be managed in accordance
with a DEQ Brownfields approved Environmental Management Plan (EMP).

Results of groundwater assessment activities indicate that TCE was detected above the 2L Standard
and DWM Residential and Non-Residential GWSLs in the southern and southwestern portions of the
Site. Based on groundwater assessment results, groundwater should be managed in accordance with

a DEQ Brownfields approved EMP if encountered during redevelopment of the Site. Additionally,
results of groundwater assessment activities and subsequent soil gas assessment activities indicate
that there is potential for structural vapor intrusion into proposed Site buildings in the western and
southwestern portions of the Site. Therefore, the PD plans to install a vapor mitigation system beneath
the proposed buildings in these areas of the Site. A vapor mitigation plan will be submitted to DEQ
for approval under separate cover prior to construction of the proposed Site buildings.
