Brownfields Assessment Report
Commercial Equipment Company
N. Graham Street and W. 28th Street
Charlotte, North Carolina
H&H Job No. ABS-003

1.0 Introduction

On behalf of Abacus Acquisitions, LLC (Abacus), Hart & Hickman, PC (H&H) has prepared
this Brownfields Assessment Report for the Commercial Equipment Company Brownfields
property (Brownfields Project No. 26002-22-060) located southeast of the N. Graham Street and
W. 28th Street intersection in Charlotte, Mecklenburg County, North Carolina (Site or subject
Site). A Site location map is provided as Figure 1.

The subject Site is comprised of four contiguous parcels (Mecklenburg County Parcel ID Nos.
07907911, 07907910, 07907909, and 07907908) that collectively total approximately 7.5 acres
of land. The northwestern portion of the Site (2402/2426 N. Graham Street) is developed with
an approximately 4,500-square foot (sq ft) office building with an approximate 1,800-sq ft
basement constructed in 1945, and the southern portion of the Site (609 W. 28th Street) is
developed with an approximately 7,350 sq ft service garage constructed in 1969. The parcels
located in the southeastern portion of the Site (2409 and 2415 Grimes Street) are developed with
single-family residences that were constructed in 1949. The Site and surrounding area are shown
in Figure 2.

Proposed redevelopment of the Site includes construction of residential for-rent townhome-style
buildings and multifamily apartment buildings with associated parking and amenities areas.
Note that construction of the for-rent townhome buildings includes ground-level parking garages
that are not connected to upper-level occupiable spaces except for a small landing and staircase
at the entrance to each unit. An overlay of the preliminary Site redevelopment plan including
locations of proposed buildings is provided as Figure 3.

A summary of Site background information including previous assessment activities conducted
at the Site is provided below.

1.1 Background Information

Prior to the late 1930s, the Site consisted predominately of undeveloped land used for
agricultural purposes (e.g., hay fields or pastures) and a rural access road. By the late 1940s, the
western portion of the Site was developed with three commercial buildings associated with a
motor freight station and auto repair facility. By the late 1950s, the southern portion of the Site
was developed with five single-family residences. In the early 1970s, the auto repair shop in the
central portion of the Site was razed and a portion of the current 609 W. 28th Street building was
constructed in the southern portion of the Site. In the 1980s and 1990s, all but two residences in
the southern portion of the Site were razed and additions to the 609 W. 28th Street building were
completed. The Site was occupied by Starnes Pallet from the early 2000s to the early 2020s.

Starnes Pallet operations included salvage of used wooden and plastic pallets. The pallets were
transported to the Site and disassembled prior to transport off-Site for recycling/re-use. In
addition, Starnes Pallet allowed customers to stage used totes and drums at the Site prior to
transport off-Site for recycling. The totes and drums were reportedly emptied and cleaned prior
to arrival at the Site.

The office building in the northwestern portion of the Site is currently unoccupied, but is used
for storage of personal items by the current property owner (Starnes Commercial Properties
LLC). The service garage building is occupied by a tractor trailer truck leasing and rental
business. The service garage in the southern portion of the Site is used for routine maintenance
and repair of the tractor trailer fleet. Remaining portions of the Site consist of asphalt paved and
gravel covered parking and storage areas. Materials stored at the Site include wooden and plastic
pallets, empty totes and drums, and construction materials including lumber, steel beams, toilets,
sinks, hot water heaters, and other debris. The two single-family residences along Grimes Street
are occupied by residential tenants.

1.2 Previous Assessment Activities

H&H recently completed Phase I ESA activities at the Site and identified the following
environmental concerns associated with historical on-Site and nearby off-Site operations:

 The Site was formerly utilized by Commercial Equipment Co. from the early 1970s until
the late 1990s. According to information provided in available environmental documents
prepared for the Site, Commercial Equipment Co. utilized one 500-gallon gasoline
underground storage tank (UST) as part of Site operations. According to the Site contact
and information provided in available environmental documents, the gasoline UST has
not been used in over 30 years but remains at the Site. H&H did not observe
aboveground evidence (e.g., vent pipes, fill ports, etc.) associated with the 500-gallon
tank during Site reconnaissance activities. The potential for an undocumented release
associated with the gasoline UST and the potential for additional unidentified USTs at the
Site was identified as a Recognized Environmental Condition (REC) in the Phase I ESA.

 Review of available environmental documents indicates that a freight depot/motor line
company and an auto repair facility with a paint booth operated in the western and central
portions of the Site in the 1950s and 1960s. The Site is not listed in the environmental
databases as a generator of hazardous wastes and there are no release incidents reported
in the environmental databases associated with hazardous wastes or historical automotive
repair operations at the Site. However, auto repair operations often include use of various
petroleum-related products and solvents for degreasing. Additional information
regarding former auto repair and freight operations was not available. Results of the
Phase I ESA identified the potential for an undocumented release or releases associated
with decades of historical on-Site auto repair and trucking operations as a REC in
connection with the Site.

 Based on information provided in available environmental documents, the 609 W. 28th
Street Site building utilized an oil/water separator (OWS) system and/or waste oil UST
until the 1990s. A steel pipe was observed at the ground surface near the southern corner
4

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/abacus capital (abs)/w. 28th and n.graham
assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
of the 609 W. 28th Street Site building and two floor drains were observed in the former
wash bay and washdown concrete pad located along the eastern side of the 609 W. 28th
Street building. Standing fluids with an oily sheen were observed within the floor drains
located in the wash bay and concrete wash pad. The pipe and drains are suspected to be
associated with the reported OWS and/or waste oil tank.

There are no release incidents associated with the OWS drain system and/or waste oil
tank and no available documentation related to routine maintenance and emptying of sub-
grade components of the systems. Based on the age of the drains and OWS system/waste
oil UST and the observed conditions of the drains, results of the Phase I ESA identified
the potential for impact to the Site from an undocumented release associated with the
floor drain and OWS system/waste oil UST system as a REC.

 Information provided in the environmental databases indicates that approximately 50-
gallons of diesel were released to the ground surface and contained using absorbent pads.
Additional information pertaining to the surface release (Incident No. 85418) was not
available in the database report or in North Carolina Department of Environmental
Quality (DEQ) UST Section records. According to information provided by DEQ UST
Section personnel, files associated with the release incident are designated as lost and the
petroleum release incident remains open. The Site contact was unaware of the reported
spill and was therefore unable to provide additional details related to the remedial effort
or subsequent sampling confirming the spill was adequately addressed to levels below
applicable screening criteria. Based on the lack of details associated with the remedial
effort and sampling information, and the open status of the release incident, the reported
on-Site surface spill was identified as a REC in the Phase I ESA.

A Historical Recognized Environmental Condition (HREC) is defined as a REC which involves
a past release of hazardous substances or petroleum products that has been addressed to the
satisfaction of the applicable regulatory authority and is not subject to activity and/or use
limitations. Results of the Phase I ESA identified the following HREC in connection with the
Site:

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
 Commercial Equipment Company installed two 12,000-gallon diesel USTs near the
southern exterior wall of the 609 W. 28th Street Site building in March 1980. Petroleum
impacted soil was discovered during closure of the two diesel USTs in March 1998, and
approximately 270 cubic yards of impacted soil was removed from the tank basin and
stockpiled on-Site (LUST Incident No. 18731). Soil samples were collected for
laboratory analysis beneath the former diesel USTs (T1-E, T2-E, T1-W, and T2-W),
along product lines (PL-1, PL-4, and PL-5), and adjacent to dispensers (D-1, D-2, and D-
3). According to information provided in the environmental documents, the product
piping and dispensers were not removed during closure activities in March 1998.

Laboratory analytical results for soil samples collected from the UST basin indicated that
total petroleum hydrocarbons as diesel range organics (TPH-DRO; up to 6,700
milligrams per kilogram {mg/kg}) and as gasoline range organics (TPH-GRO; up to 500
mg/kg) were detected at concentrations above the DEQ UST Section Residential
Maximum Soil Contaminant Concentrations (MSCCs) at the time. Note that there are no
current MSCCs for TPH and the current DEQ UST Section Action Levels for TPH-DRO
and TPH-GRO are 100 mg/kg and 50 mg/kg, respectively. In addition to TPH, UST
basin soil sample results identified the presence of several additional petroleum-related
compounds including n-butylbenzene, sec-butylbenzene, naphthalene, 1,2,4-
trimethylbenzene, 1,3,5-trimethylbenzene, isopropyl benzene, total xylenes, and 2-
methylnaphthalene at concentrations above the DEQ UST Section Soil-to-Water MSCCs.

Product line soil sample results indicated that naphthalene and 2-methyl naphthalene
were detected in one sample at concentrations exceeding the Soil-to-Water MSCC.
Laboratory analytical results for soil samples collected in the area near the dispensers did
not identify organic compounds at concentrations above the DEQ UST Section MSCCs.

In June 1998, one monitoring well (MW-1) was installed and sampled in the area of the
former diesel UST basin. Soil samples collected from the monitoring well boring did not
indicate the presence of compounds at concentrations above the DEQ UST Section
MSCCs with the exception of C9-C10 aromatics hydrocarbon fractions which were
6

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
detected at a concentration slightly above the Soil-to-Water MSCC. Laboratory
analytical results for the groundwater sample collected from the monitoring well
indicated the presence of benzene, naphthalene, and C9-C22 aromatics at concentrations
above the DEQ 2L Groundwater Quality Standards (2L Standards), but below the DEQ
UST Section Gross Contamination Levels (GCLs).

Information provided in a Limited Site Assessment (LSA) report prepared for the Site on
October 23, 1998, by Altura Environmental, indicates that three additional shallow
monitoring wells (MW-2, MW-3, MW-4) were installed south of the former diesel UST
basin, adjacent to the product piping, and topographically downgradient of the former
diesel USTs, respectively. In addition, one deeper monitoring well (MW-1A) was
installed near existing well MW-1. Groundwater samples were collected for laboratory
analysis from each monitoring well (MW-1 through MW-4 and MW-1A). Groundwater
sample laboratory analytical results for groundwater samples collected from monitoring
well MW-1 identified benzene, naphthalene, C9-C-22 aromatics, and ethylbenzene at
concentrations above the 2L Standards. The compounds naphthalene and 2-
methylnaphthalene were detected in deeper well MW-1A at concentrations above the 2L
Standards. Petroleum-related compounds were not detected at concentrations above the
laboratory reporting limits in samples collected from the remaining monitor wells.

Based on results of assessment activities and risk evaluations, the DEQ UST Section
assigned a low-risk designation to the incident. On November 6, 1998, the DEQ UST
Section issued a No Further Action (NFA) letter providing regulatory closure for the
release. Information provided in the NFA letter indicates contaminated groundwater has
not been remediated to levels below the 2L Standards and is not a suitable water supply
source. However, a Notice of Residual Petroleum (NORP) restricting groundwater use or
other activity use limitations was not recorded on the property deed. Based on regulatory
closure of the release incident without activity or land use restrictions recorded on the
property deed, the release incident associated with the former diesel USTs represents an
HREC in connection with the Site.

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
To address environmental concerns, the Site was entered into the DEQ Brownfields
Redevelopment Section as a part of property transaction due diligence activities. A Brownfields
Property Application was submitted to DEQ on January 12, 2022, and a Letter of Eligibility was
issued for the Site by DEQ on May 24, 2022. Because the Site was entered into the Brownfields
Redevelopment Section, H&H completed Phase II ESA soil, groundwater, and soil gas sampling
consistent with assessment activities typically requested by DEQ Brownfields. In addition, H&H
completed a receptor survey as part of the Phase II ESA activities, a brief summary of the Phase
II ESA soil, groundwater, and soil gas sampling results is provided below.

2022 Phase II ESA
In February 2022, H&H performed Phase II ESA activities at the Site to evaluate the potential
for impacts and assist in the management of Site media during planned redevelopment activities.
Assessment activities included the advancement of seven (7) soil borings near areas of concern
(i.e., drains, former and suspect USTs, former dispenser islands, and an OWS/waste oil UST
system), and five (5) composite soil samples were collected from shallow soil that will likely be
disturbed during future redevelopment. Assessment activities also included groundwater sample
collection from five (5) temporary monitoring wells installed in upgradient areas of the Site to
evaluate the potential for impact from nearby off-Site properties, areas of potential concern, and
in areas downgradient of the existing Site buildings. Additionally, eight (8) exterior soil gas
samples and two (2) sub-slab soil gas samples were collected for laboratory analysis within or
near the footprint of proposed for-rent apartment buildings to evaluate the potential for structural
vapor intrusion.

Although there is no known historical landfilling, dumping, waste disposal, or other operations
that would result in a subsurface source of methane at the Site, subsurface methane and
differential pressure measurements were collected from each exterior soil gas and sub-slab soil
gas monitoring point location to minimize the potential for data gaps associated with the
redevelopment of a Brownfields property for residential use. Soil, groundwater, and soil gas
sample locations from the February 2022 Phase II ESA are depicted in Figure 3, and summaries
of the analytical results are provided in Appendix A.

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
Results of soil sampling activities completed in areas planned for disturbance during future
grading and redevelopment on the Site did not identify organic compounds at concentrations
above the DEQ Preliminary Soil Remediation Goals (PSRGs). Results of the soil assessment
activities completed in the areas near the former USTs, dispenser islands, wash bay, and
OWS/waste oil UST system did not identify compounds at concentrations above the DEQ
PSRGs or background concentrations in the case of metals. Concentrations of arsenic (COMP-1)
and lead (COMP-3) were detected at concentrations above the DEQ Residential PSRGs and
regional background concentrations for metals in shallow soil that may be disturbed during
redevelopment. Remaining metal concentrations detected in soil samples collected at the Site are
consistent with published and established naturally occurring levels.

Results of the groundwater sampling identified several organic compounds above 2L Standards
and/or DEQ Vapor Intrusion Groundwater Screening Levels (GWSLs), including carbon
tetrachloride, chloroform, 1,2-dichloroethane, 1-methylnaphthalene, naphthalene,
tetrachloroethene (PCE), and trichloroethene (TCE). Total chromium was detected above the 2L
Standard in TMW-3.

Results of the soil gas assessment activities identified several compounds at concentrations
above the DEQ Vapor Intrusion Sub-slab and Exterior Soil Gas Screening Levels (SGSLs). The
chlorinated solvents PCE and TCE were not detected at a concentration above the DEQ Vapor
Intrusion SGSLs in soil gas samples collected at the Site.

Risk calculator results using compound concentrations detected in the soil gas samples indicate
that the Site-wide worst-case calculated cumulative lifetime incremental carcinogenic risk
(LICR) is less than the acceptable risk level of 1 x 10-4. However, the cumulative
noncarcinogenic hazard index (HI) exceeds the DEQ and Environmental Protection Agency
(EPA) acceptable threshold and 1.0. Risk calculator results using the compound concentrations
detected in the sub-slab soil gas samples collected within the existing Site buildings did not
exceed unacceptable risk thresholds under a residential use scenario.

Results of the methane gas measurements identified the presence of methane up to 7.0% by
9

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/abacus capital (abs)/w. 28th and n.graham
assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
volume air (bv) in the southeastern portion of the Site (SG-5/SG-DUP), which is above the lower
explosive limit (LEL) of 5% bv for methane. However, the presence of methane in the
subsurface is not present at concentrations above the DEQ Brownfields Program 30% bv
residential use threshold. Methane concentrations were not detected above the LEL in remaining
soil gas sample locations at the Site. Pressure measurements collected at the Site are within the
accuracy limits for the instrument and are not present at levels that would allow subsurface
methane to migrate vertically to the surface at potentially explosive concentrations.

Brownfields Activities
As part of the Brownfields process, a kick-off/data gap meeting with the PD, environmental
counsel for the PD, DEQ Brownfields personnel, and H&H was held on September 15, 2022, to
discuss prior Site history, proposed redevelopment plans, previous sampling data, and the
proposed schedule for completing the Brownfields Agreement. Based on results of previous
assessment activities and discussions during the data gap/kick-off meeting, in an email dated
November 16, 2022, DEQ Brownfields requested collection of additional soil samples and sub-
slab soil gas samples. In addition, DEQ Brownfields Redevelopment Section requested
collection of subsurface methane readings to further evaluate the extent of potential measurable
subsurface methane.

H&H prepared a Brownfields Assessment Work Plan (Work Plan) and revisions to the Work
Plan based on DEQ Brownfields comments to address the requested additional assessment
activities. The Work Plan received DEQ-approval in a letter dated March 30, 2023. This report
has been prepared to document the additional soil, soil gas, and methane sampling activities
completed at the request of DEQ Brownfields and in accordance with the DEQ-approved Work
Plan.

A summary of the Brownfields assessment sampling activities and results is provided in the
sections below.

2.0 Brownfields Assessment Activities

Brownfields assessment activities included collection of confirmation soil samples in the
northern, central, and eastern portions of the Site where organic compounds or metals were
detected in February 2022 Phase II ESA samples. Based on the size of the 609 W. 28th Street
Site building (approximately 7,350 sq ft) one (1) additional sub-slab soil gas sample was
collected as part of Brownfields assessment activities. Based on the proposed redevelopment
plan, four (4) additional exterior soil gas samples were collected within the footprint of proposed
townhome-style apartment buildings. In addition, subsurface methane and differential pressure
measurements were collected from nine (9) soil gas sampling points installed in the southern
portion of the Site where measurable levels of methane were identified in February 2022.

Prior to conducting field activities, H&H contacted North Carolina 811, the public utility locator,
to mark subsurface utilities at the Site. H&H also contracted with a private utility locator, to
mark utilities which were not identified by the public locator. The private utility locator also
utilized ground penetrating radar (GPR) survey techniques to identify and mark utilities at each
sample location. In addition, H&H directed the drilling contractor to hand clear each boring to a
depth of approximately 5 feet below the ground surface (ft bgs) to further screen the boring
locations for the presence of subsurface utilities.

The assessment activities described herein were performed in general accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of
Contaminated Sites (Guidelines) dated September 2022, the DEQ Division of Waste
Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated March 2018, DEQ
Brownfields Program Methane Assessment Protocol dated September 2020, the most recent
versions of the U.S. Environmental Protection Agency (EPA) Region IV Laboratory Services
and Applied Science Division (LSASD) guidance, the Los Angeles Department of Building
Safety (LADBS) Site Testing Standards for Methane dated January 2014, the DEQ Brownfields
Methane Assessment Protocols dated September 2020, and the DEQ-approved Work Plan.

Brownfields assessment activities and results are provided in the following sections.

3.0 Additional Soil Assessment Activities

On April 13 and 14, 2023, H&H contracted Mid South Environmental, Inc. (Mid South) to
advance soil borings in areas of the Site where field screening identified volatile organic vapors
measurements above background levels during Phase II ESA sampling activities and where
laboratory analytical results identified lead at concentrations above background levels in a
composite soil sample. Soil samples were collected for laboratory analysis at each boring
location to further evaluate the potential for impact and assist in managing soil at the Site during
planned redevelopment activities. The locations of the soil borings are shown in Figure 3.

Soil borings were advanced utilizing a decontaminated stainless-steel hand auger, and a
track-mounted direct push technology (DPT) drill rig. During boring advancement, continuous
soil samples were collected from the center of the hand auger bucket or from acetate-lined
macrocore sleeves. The soil samples were logged for lithologic description, observed for
obvious evidence of staining and unusual odors, and field screened for the presence of volatile
organic vapors using a calibrated photoionization detector (PID). H&H did not observe obvious
evidence of potential impacts in the soil samples based on results of field screening. Boring logs
including lithologic descriptions and field screening results for each soil boring are provided in
Appendix B.

A discussion of the soil sampling activities and results is provided in the following sections.

3.1 Soil Sampling Activities

Confirmation Soil Sampling – Northern, Central, and Eastern Deeper Soil
Confirmation soil samples were collected for laboratory analysis from previous Phase II ESA
borings where field screening results indicated potential impacts as described below.

 Two soil borings (BF-SB-01 and BF-SB-02) were advanced in the northern corner of the
Site near Phase II ESA borings SG-1 and TMW-1. The soil borings were advanced to
approximately 10 ft bgs. Based upon field observations, one soil sample was collected
12

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/abacus capital (abs)/w. 28th and n.graham
assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
from each boring location for laboratory analysis from the 5-7 ft bgs depth interval to
evaluate the potential for impact at a depth greater than 2 ft bgs as requested by the DEQ
Brownfields Redevelopment Section.

 One soil boring (BF-SB-03) was advanced in the central portion of the Site near Phase II
ESA soil gas sampling point boring SG-6. The soil boring was advanced to
approximately 10 ft bgs. Based upon field observations, a sample was collected from the
4-5 ft bgs depth interval to evaluate the potential for impact at a depth greater than 2 ft
bgs as requested by the DEQ Brownfields Redevelopment Section.

 Two soil borings (BF-SB-04 and BF-SB-05) were advanced in the eastern portion of the
Site near Phase II ESA borings SG-2 and SG-3. Soil borings were advanced to
approximately 10 ft bgs. Based upon field observations, one soil sample was collected
for laboratory analysis from each boring from the 2-4 ft bgs depth interval to evaluate the
potential for impact at a depth greater than 2 ft bgs as requested by the DEQ Brownfields
Redevelopment Section.

Soil samples selected for laboratory analysis were placed in dedicated laboratory supplied
sample containers, labeled with the sample identification, date, and requested analysis, and
placed in a laboratory supplied cooler with ice. The samples were delivered to Pace Analytical
(Pace), a North Carolina certified laboratory, under standard chain of custody protocols for
laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi-VOCs
(SVOCs) by EPA Method 8270, Resource Conservation and Recovery Act (RCRA) metals by
EPA Methods 6020/7471, and hexavalent chromium by EPA Method 7199.

Composite Soil Sample – Central Shallow Soil
In addition to the soil sampling described for the northern, central, and eastern portions of the
Site above, six (6) shallow soil borings were advanced for the collection of soil samples in the
central portion of the Site to further evaluate soil conditions near the Phase II ESA composite
soil sample COMP-3 aliquot soil borings. The shallow soil boring locations (identified as
COMP-3A through COMP-3F) are shown in Figure 3.

The drilling contractor advanced each soil boring with a decontaminated stainless steel hand
auger and continuous soil samples were collected from the center of the hand auger bucket. Soil
samples for laboratory analysis were collected from the ground surface to approximately 2 ft bgs
at each boring location. The soil samples selected for laboratory analysis were collected directly
into laboratory-supplied glassware, labeled with the date, time, and sample identification, and
placed in a laboratory supplied sample cooler with ice. The samples were submitted to a Pace
under standard chain of custody protocols for analysis of lead by EPA Method 6020.

Following completion of the confirmation soil sampling activities, the soil borings were properly
abandoned, and the ground surface was repaired similar to pre-drilling conditions. In addition,
soil boring locations were estimated using a hand-held global positioning system (GPS) unit.

3.2 Soil Sampling Analytical Results

A tabular summary of the soil sample analytical results is presented in Table 1, and copies of the
laboratory analytical reports and chain of custody records are provided in Appendix C. The
laboratory analytical results were compared to the most recent version of the DEQ Residential
and Industrial/Commercial PSRGs dated January 2023. Metals results were compared to
published concentrations for naturally occurring metals in regional soil (Dragun and Chekiri
2005) and background levels established for a nearby Brownfields property (Cotton Warehouse -
Brownfields Project No. 24013-20-060).

A discussion of the confirmation soil sample laboratory analytical results is provided below.

Confirmation Soil Sampling – Northern, Central, and Eastern Deeper Soil
Soil sample analytical results indicate that an estimated level of ethylbenzene (0.0039 J mg/kg)
was detected in soil sample BF-SB-01 collected in the northern portion of the Site at a
concentration above the laboratory method detection limit, but below the laboratory reporting
limit (J-flag), and well below the DEQ PSRGs. Trace levels of methylene chloride (up to 0.147
C9 mg/kg), a laboratory introduced contaminant (C9 Flag), were detected at concentrations
above the laboratory method detection limits in each soil confirmation soil sample. No other

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
organic compounds were detected at concentrations above the laboratory method detection limits
in confirmation soil samples collected in the northern, central, and eastern portion of the Site.

Several metals were detected in each confirmation soil sample at concentrations generally
consistent with naturally occurring background levels including arsenic (up to 2.9 mg/kg),
barium (up to 19.1 mg/kg), trivalent chromium (up to 146 mg/kg), hexavalent chromium (up to
0.921 J mg/kg), lead (up to 10.3 mg/kg), mercury (up to 0.13 mg/kg), and selenium (up to 1.1
mg/kg). Although generally consistent with expected background concentration, levels of
concentrations of total chromium detected in the BF-SB-03 (124 mg/kg) soil sample and its
duplicate soil sample BF-SB-DUP (139 mg/kg), and soil sample BF-SB-04 (147 mg/kg) exceed
the Rule of 20 for toxicity characteristic of 100 mg/kg. Therefore, these samples were submitted
for additional chromium analysis using Toxicity Characteristic Leaching Potential (TCLP)
methods. Results of the TCLP analysis indicate that chromium was not detected at
concentrations above the laboratory method detection limits in the leachate samples.

Composite Soil Sampling – Central Shallow Soil
Composite soil sample laboratory analytical results indicate that lead (ranging from 12.3 mg/kg
to 309 mg/kg) was detected at concentrations above the laboratory method detection limits, but
below the DEQ Residential PSRG of 400 mg/kg in each shallow soil sample collected in the
central portion of the Site. The lead concentration detected in soil sample COMP-3E (309
mg/kg) exceeds the Rule of 20 for toxicity characteristic of 100 mg/kg. Therefore, this sample
was submitted for additional lead analysis using TCLP methods. Results of the TCLP analysis
indicate that lead was not detected at concentrations above the laboratory method detection limits
in the leachate.

4.0 Additional Soil Gas Assessment Activities

In April 2023, H&H installed and sampled four (4) temporary exterior soil gas monitoring points
(SG-9 through SG-12) and one (1) temporary sub-slab soil gas sampling point (SSV-3) within or
near the footprint of proposed residential buildings to further evaluate the potential for structural
vapor intrusion. The exterior and sub-slab soil gas sampling point locations are shown in Figure
3. The vapor intrusion assessment activities and results are described below.

4.1 Soil Gas Sampling Activities

Exterior Soil Gas Sample Point Installation
Under the direction of H&H, Mid South advanced four (4) soil borings for installation of
temporary exterior soil gas monitoring points (SG-9 through SG-12) within the footprint of the
proposed residential buildings (Figure 3).

The soil gas monitoring points were installed at depths of 7 ft bgs and above the estimated water
table capillary fringe. Each soil boring was advanced using DPT drilling methods. Continuous
soil samples were collected from the soil gas monitoring point borings and logged for lithologic
description, observed for obvious evidence of staining and unusual odors, and field screened for
the presence of volatile organic vapors using a calibrated PID. Field screening results did not
indicate obvious evidence of potential impacts in the soil gas monitoring point borings.

Once at target depth, a six-inch stainless steel vapor implant screen attached to a length of
Teflon® tubing was installed at the base of each borehole. Filter sand was then placed within the
annulus of the boring from the base of the boring to a depth of approximately 6-inches above the
top of the vapor screen. The sampling points were completed by placing hydrated bentonite
from the top of the filter sand to the ground surface. Boring logs including lithologic
descriptions, field screening results, and soil gas monitoring point construction details are
provided in Appendix B.

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
Sub-Slab Soil Gas Sample Point Installation
H&H installed one (1) sub-slab soil gas sample point (SSV-3) within the vacant office portion of
the Site building located at 609 w. 28th Street (Figure 3). The sub-slab soil gas sampling point
was installed using a rotary hammer drill and 1½-inch diameter drill bit to advance a pilot hole
into the concrete slab to a depth of approximately 1¾ inches below the surface. A drill guide
was then placed in the pilot hole and a 5/8-inch diameter drill bit was utilized to advance the
boring through the concrete slab and approximately 6-inches into the underlying soil. Following
concrete borehole advancement, loose concrete cuttings were removed from each boring using a
bottlebrush. A Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone
sleeve) was then seated in the borehole using an installation/extraction tool and hammer. Upon
installation of the vapor pin assembly, dedicated Teflon® sample tubing was connected to the
barbed end of the sample point.

Soil Gas Sampling
Each exterior and sub-slab soil gas sample was collected utilizing a laboratory supplied 1.4-liter
Summa® canister connected to an air-flow regulator calibrated by the laboratory to collect the
soil gas sample at a rate of no greater than approximately 200 milliliters per minute (mL/min).
Prior to collection of the soil gas samples, “shut-in” tests were conducted on the sampling train
and helium leak checks were conducted at each sampling point. A description of the shut-in test
and helium leak testing procedures is provided below.

The shut-in test was conducted by connecting the flow regulator with the vacuum gauge to the
Summa® canister and sealing the flow regulator with the laboratory provided brass cap. Once
the sampling train was “closed”, the sample valve on the Summa® canister was opened and the
reading on the vacuum gauge was recorded. The Summa® canister sample valve was then closed
and the vacuum gauge was observed to ensure no vacuum loss occurred. If the vacuum reading
remained the same, the shut-in test was considered successful. Shut-in tests were considered
successful for each sample canister.

Following successful shut-in tests, the Summa® canister was connected to the sample point via
Teflon® sample tubing using a brass nut and ferrule assembly to create an air tight seal and a leak
17

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
check was performed. The leak check was performed by constructing a shroud over the
sampling point and sampling train, and flooding the shroud with helium gas. Helium
concentrations inside the shroud were measured using a calibrated helium gas detector and
maintained at concentrations ranging from approximately 5.1% to 6.8%. Once helium
concentrations stabilized within the shroud, the sample tubing was purged outside of the shroud
using a syringe and a three-way valve to collect purged soil gas into a Tedlar® bag. The purged
soil gas was then analyzed using the helium gas detector to ensure that helium concentrations in
the soil gas sample were less than 10% of the helium concentrations measured within the shroud.
Each soil gas sampling point passed the helium leak check criteria.

Following successful leak checks, the soil gas samples were collected by opening the intake
valve on the Summa® canister. Vacuum readings on the Summa® canister were recorded prior to
and following the sampling period to ensure adequate sample volume was collected. A vacuum
of approximately 5 inches of mercury or more was maintained within the canisters at the
conclusion of the sampling event in accordance with DEQ DWM VI Guidance. Following
sample collection, the Summa® canisters were shipped to Waypoint Analytical under standard
chain of custody protocols for analysis of VOCs by EPA Method TO-15. Upon receipt of the
samples, the laboratory recorded the final received vacuum pressure for each Summa® canister.

After sampling was completed, the sample locations were estimated by measuring from known
benchmarks within the Site building for SSV-3 and using a GPS unit for the exterior locations.
The sample locations were permanently abandoned, and the surfaces were repaired similar to
pre-drilling conditions.

4.2 Soil Gas Sampling Results

A tabular summary of the soil gas sample analytical results is provided as Table 2, and a copy of
the laboratory analytical report and chain of custody record is provided in Appendix C. The soil
gas sample results were compared to DEQ Residential and Non-Residential Vapor Intrusion Sub-
Slab and Exterior Soil Gas Screening Levels (SGSLs) dated January 2023. A brief summary of
the exterior and sub-slab soil gas sampling results is provided below.

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
Exterior Soil Gas Sample Results
The following petroleum-related compounds were detected at concentrations above the DEQ
Vapor Intrusion SGSLs in the April 2023 exterior soil gas samples collected at the Site:

 Benzene (up to 148 µg/m3) was detected in soil gas samples SG-9, SG-10, and SG-12 at
concentrations above the DEQ Residential SGSL of 12 µg/m3.
 1,3-butadiene (up to 45.7 µg/m3) was detected in soil gas samples SG-9, SG-10, and SG-
12 at concentrations above the DEQ Residential SGSL of 3.1 µg/m3. The detected
concentration in SG-10 (45.7 µg/m3) also exceeds the Non-Residential SGSL of 41
µg/m3. Note that 1,3-butadiene is commonly attributed to off gassing of rubber seals
associated with DPT drilling equipment used to install the sampling points and its
presence in the soil gas samples is not likely associated with soil gas conditions at the
Site.
 Chloroform (5.52 µg/m3) was detected in soil gas sample SG-10 at a concentration above
the DEQ Residential SGSL of 4.1 µg/m3.
 Ethylbenzene (up to 388 µg/m3) was detected in SG-9 through SG-12 at concentrations
above the DEQ Residential SGSL of 37 µg/m3.
 Naphthalene (6.26 µg/m3) was detected in soil gas sample SG-9 at a concentration above
the DEQ Residential SGSL of 2.8 µg/m3.
 Xylenes (up to 1,720 µg/m3) were detected in soil gas samples SG-9, SG-10, and SG-12
at concentrations above the DEQ Residential SGSL of 700 µg/m3.

No other compounds, including chlorinated solvents, were detected at concentrations above the
DEQ Vapor Intrusion SGSLs in the exterior soil gas samples. This is consistent with the results
of Phase II ESA soil gas sampling activities completed at the Site in February 2022.

Sub-Slab Soil Gas Sampling Points
Laboratory analytical results indicate that several compounds were detected at concentrations
above the laboratory method detection limits in the sub-slab soil gas sample collected within the
609 W. 28th Street Site building. No compounds, including chlorinated solvents, were detected
at concentrations above the DEQ Vapor Intrusion SGSLs in the SSV-3 sub-slab soil gas sample.

collected from the office building. This is consistent with the results of Phase II ESA sub-slab
soil gas sampling activities completed at the Site in February 2022.

4.3 Vapor Intrusion Risk Evaluation

The DEQ Vapor Intrusion SGSLs are very conservative and based upon a target cancer risk
(TCR) of 1 x 10-6 for potential carcinogenic effects and a target hazard quotient (THQ) of 0.2 for
potential non-carcinogenic effects. Vapor intrusion mitigation or additional assessment is not
typically warranted if the calculated cumulative lifetime incremental carcinogenic risk (LICR) is
1 x 10-4 or less and the acceptable level for non-carcinogenic risk is a calculated cumulative
hazard index (HI) of 1.0 or less.

H&H utilized the DEQ Risk Calculator (January 2023) assuming residential land use to further
evaluate potential cumulative risks for the soil gas to indoor air vapor intrusion pathway. To
model the potential for vapor intrusion risks under a hypothetical “worst-case” scenario, H&H
conservatively calculated the cumulative risks using the highest concentration of any compound
detected in any soil gas sample collected from the Site for both the February 2022 Phase II ESA
and the April 2023 Brownfields assessment. Risk calculator results are summarized in the table
below. A copy of the completed risk calculators is provided in Appendix D.

Risk calculator results indicate that under a hypothetical worst-case scenario for the soil gas to
indoor air vapor intrusion pathway for residential use, the cumulative LICR is less than the
acceptable risk level of 1 x 10-4. However, the cumulative HI for residential use is greater than
the acceptable risk level of 1.0.

Results of assessments completed at the Site indicate that TCE has not been detected in soil or
soil gas at concentrations above the laboratory method detection limit. However, a trace level of

TCE (1.6 µg/L) was detected at a concentration above the laboratory method detection limit in
one groundwater sample (TMW-6) collected at the Site in February 2022. Based on review of
the DEQ DWM draft Minimum Mitigation and Sampling Requirements for Reuse dated
February 2023 and results of assessments completed at the Site, potential vapor intrusion risks at
can easily be managed through the installation of DEQ-approved passive vapor intrusion
mitigation systems designed with the capability to be converted to active sub-slab
depressurization systems if warranted.

5.0 Subsurface Methane Gas and Pressure Measurements

Results of the February 2022 Phase II ESA identified subsurface methane gas in soil gas
monitoring point SG-5 collected in southern portion of the Site near the Franklin Avenue right of
way (Figure 3). Although there is no indication or reports of historical landfilling, dumping, or
subsurface waste disposal at the Site, subsurface methane gas was measured in SG-5 at
concentrations up to 7.0% bv, which exceeds the atmospheric LEL for methane.

To confirm the presence of subsurface methane gas in the southern portion of the Site, H&H re-
installed soil gas monitoring point SG-5 and collected additional subsurface methane and
pressure measurements. In addition, H&H installed eight (8) additional “step-out” soil gas
monitoring points (MP-A through MP-H) in each cardinal direction away from the SG-5
replacement sampling point to evaluate the extent and potential source of subsurface methane
gas. The approximate locations of the monitoring points are shown on Figure 3.

5.1 Methane Gas Sampling Activities

On April 16, 2023, the methane monitoring points were installed to a depth of 7 ft bgs, which is
above the estimated water table capillary fringe. Monitoring point borings were advanced at
each proposed location using a stainless-steel decontaminated hand auger and DPT drilling
techniques. An approximate 6-inch stainless steel vapor implant screen attached to Teflon®
sample tubing was then placed at the base of the borehole. The annular space around the vapor
implant screen was filled with filter sand to a depth of approximately 6-inches above the vapor
screen. Following installation of the sand, hydrated bentonite was installed in the boring from
the top of the sand to near the ground surface.

The sample tubing for each exterior monitoring point was capped using an airtight petcock valve
immediately following installation to allow subsurface conditions to equilibrate. Each point was
allowed to equilibrate for a minimum of 24-hours after installation and prior to the collection of
field measurements in accordance with DEQ VI Guidance and the DEQ Brownfields Program
Methane Assessment Protocol. After allowing for subsurface equilibration, H&H collected both
22

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/abacus capital (abs)/w. 28th and n.graham
assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
static and differential pressure readings from each monitoring point on April 17, 2023. The
pressure readings were collected using a Landtec Gem 5000® and were collected prior to
performing helium leak checks (described in Section 5.1 above). Note that the static pressure
measurement collected from a soil gas point using the Landtec Gem 5000® instrument represents
the differential pressure between the subsurface and the atmosphere.

Following collection of the pressure readings, helium leaks checks were completed at each
sampling point. After subsurface equilibration and successful leak checks, a Landtec Gem
5000® was connected to the sample tubing and field measurements of oxygen, carbon dioxide,
carbon monoxide, hydrogen sulfide, and methane (percent by volume and percent lower
explosive limit) were collected and recorded by sampling personnel. After completion of the
first round of measurements, H&H capped the points with an airtight valve for a minimum of 24-
hours prior to collection of a second round of subsurface landfill gas measurements on April 18,
2023.

Following the second round of subsurface landfill gas measurements, the sample tubing at each
sampling point was secured with an airtight valve and allowed to equilibrate for approximately
two weeks. H&H returned to the Site on May 1 and 2, 2023, and collected a third and fourth
round of subsurface landfill gas measurements at each sample location using the same methods
described above.

Following completion of the fourth round of measurements, the soil gas points were permanently
abandoned, and the surfaces were repaired similar to pre-drilling conditions. In addition, the
location of each sampling point was estimated using a handheld GPS unit.

5.2 Methane Gas Sampling Results

The landfill gas and pressure measurements are summarized in Table 3 and copies of raw data
output obtained from the Landtec Gem 5000® meter are provided in Appendix F.

Methane gas poses a potential risk of explosion when present in the atmosphere or in enclosed
23

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/abacus capital (abs)/w. 28th and n.graham
assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
spaces between a LEL of 5% bv and an upper explosive limit (UEL) of 15% bv. There is no
LEL for soil gas as a typical soil matrix stops propagation of flame in the subsurface preventing
methane in soil gas from exploding. Therefore, the LEL at 1 atmosphere of 5% by volume air
was used as a conservative comparison to detectable levels of methane in Site soil gas. In
addition, the NCDEQ Brownfields Program Threshold Criteria for Methane Site Development
dated December 2020 identifies 30% methane by volume air in soil gas and measurable static
pressure within 200 feet of a building as residential use thresholds. Based on the proposed
redevelopment, H&H used the DEQ Brownfields Program 30% methane bv in soil gas and
pressure thresholds for further comparison to measurements collected at the Site.

As shown in Table 3, methane was identified at measurable concentrations in each MP up to
0.6% bv. Methane was not measured at concentrations above the LEL, or the DEQ Brownfields
Program 30% bv residential use screening criteria during the April or May 2023 evaluations.

5.3 Methane Vapor Intrusion Risk Evaluation

As discussed above, methane gas may pose a potential risk of explosion when present in the
atmosphere or enclosed spaces at levels between 5% and 15% by volume air. Soil is a flame
arrestor which prevents the propagation of flame in the subsurface rendering methane in soil gas
non-explosive at any concentration. Therefore, a driving mechanism (such as a pressure
gradient) is needed to move methane in soil gas to the surface for there to be a potential risk of
explosion. To evaluate potential risks associated with methane in soil gas, methane levels, static
pressure measurements are collected concurrently at each sample interval at each sample location
to evaluate subsurface to atmospheric differential pressure.

Methane gas in the atmosphere has a very rapid diffusivity rate (approximately 0.22 square
centimeters per second [cm2/s] at 70°F)1 as compared to a common petroleum-related compound
such as benzene (approximately 0.09 cm2/s at 70°F)2. It is generally accepted that without
pressure-driven advective flow created by greater than 2 inches of water differential pressure in

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
the subsurface, the rate of methane gas diffusion is too rapid for large volumes of methane in soil
gas to reach the surface at potentially explosive levels (Proposed Regulatory Framework for
Evaluating the Methane Hazard due to Vapor Intrusion; Bart Eklund; 2011).

As noted above, the static pressure as measured by the Landtec Gem 5000® is the pressure
reading at the screened interval relative to ambient air at the instrument station. A positive static
pressure reading indicates that subsurface pressure is higher than the ambient pressure at the
instrument and is the differential pressure measurement used to evaluate the presence of
increased subsurface pressure. Based on information provided by the manufacturer, which is
provided as a supporting document in Appendix F, the accuracy of the GEM meter is +/- 2 in
H2O for static pressure which is consistent with the generally accepted differential pressure
needed to drive methane in the subsurface to the surface at potentially explosive levels.

Results of differential pressure measurements did not identify pressure in the subsurface above
the accuracy limits of the instrument. Based on the results of the methane screening activities,
methane gas in the subsurface is not present at levels that may pose a potential explosion risk and
Site-wide static pressure is not present at levels above the accuracy threshold of the instrument
and do not pose a significant concern for the Site as a whole.

In accordance with the NCDEQ Brownfields Program Threshold Criteria for Methane Site
Development, the negligible static pressure levels measured at the Site within 200 feet of the
proposed building are acceptable for residential use. In addition, methane in soil gas is not
present at levels above the DEQ Brownfields 30% methane by volume air in soil gas residential
use threshold. Therefore, results of the assessment activities confirm that subsurface methane
gas does not pose a potential risk at the Site and methane mitigation of the proposed Site
buildings is not warranted.

6.0 Quality Assurance – Quality Control

For quality assurance and quality control purposes (QA/QC), non-dedicated equipment and tools
were decontaminated prior to use at each boring or sampling location or following exposure to
soil and groundwater. Field QA/QC samples were analyzed along with the investigative samples
to determine potential variability introduced in sampling, handling, shipping, and analysis. H&H
collected duplicate soil and soil gas samples to evaluate the ability of the laboratory to reproduce
sample results. Duplicate samples were submitted to the laboratory for the same analysis as the
corresponding parent sample.

6.1 Field Duplicates

Duplicate samples were collected to evaluate the precision of the field sampling procedures,
sample matrix variability, and analytical reproducibility. Duplicate soil and groundwater
samples were collected directly into individual laboratory supplied sample containers using
sampling methodologies described in previous sections. The duplicate soil gas sample was
collected concurrently with the parent sample using a laboratory supplied T-fitting which allows
for collection of two soil gas samples from one soil gas sampling point simultaneously. The
samples were analyzed for the same parameters as the parent samples, and the analytical results
were compared with those of the parent sample. The analytical results of the parent sample and
the duplicate sample were used to evaluate the cumulative precision of the analytical method,
sample matrix, and sample collection techniques.

H&H also collected confirmation methane and pressure measurements at sample location MP-B
as part of each round of sampling. The confirmation gas and pressure measurements were
collected approximately 10 minutes after collection of the parent measurements. Without an
extensive sub-surface investigation to monitor sub-surface pressure changes over time, H&H
cannot definitively calculate or model decreases in soil gas concentrations and pressure over a
10-minute time interval following collection of the parent measurement. The measurement
collection process does not include removal of significant volumes of air. Therefore, the
confirmation sample results were used to validate the parent sample results.

Duplicate sample laboratory analytical results for each sample media are presented in the
summary tables (Table 1 for soil, Table 2 for soil gas, and Table 3 for methane and pressure
measurements). Review of the duplicate sample results in comparison to the parent sample
results indicate that the duplicate samples had acceptable reproducibility.

7.0 Summary and Conclusions

H&H completed Brownfields assessment activities at Commercial Equipment Company
Brownfields property located at N. Graham Street and W. 28th Street in Charlotte, Mecklenburg
County, North Carolina. The Site is located in a rapidly densifying area surrounding Camp
North End and in close proximity to uptown Charlotte. Brownfields assessment activities
included the collection of soil and soil gas samples for laboratory analysis to evaluate the
potential for impacts at the Site associated with historical on-Site and nearby off-Site operations
and to evaluate risks associated with proposed redevelopment of the Site. H&H also collected
subsurface methane gas and pressure measurements at the Site to evaluate the potential presence
of a subsurface methane source. A brief summary of the assessment activities is provided below.

Soil
Soil sample analytical results indicate that no organic compounds were detected at
concentrations above the DEQ Residential PSRGs in soil samples collected in areas where
volatile organic vapors were identified at levels above background in select February 2022 Phase
II ESA soil borings.

Several metals were detected at concentrations generally consistent with background levels in
soil samples collected at the Site. Total chromium concentrations exceeded the Rule of 20 for
toxicity characteristic in two soil sample locations. However, the results of TCLP analysis
indicate that chromium was not detected in the leachate at concentrations above the laboratory
method detection limits.

Lead was detected at concentrations consistent with background levels in five of the six shallow
soil samples collected at February 2022 Phase II ESA composite soil sample COMP-3 aliquot
boring locations. The lead concentration detected in the COMP-3E soil sample is below the
DEQ Residential PSRG but exceeds the Rule of 20 for toxicity characteristics. Results of TCLP
analysis indicate that lead was not detected at concentrations above the laboratory method
detection limit in the COMP-3E leachate.

assembly/brownfields/bf assessment/final/26002 - brownfields assessment report_commercial equipment company.doc
Soil Gas
Results of the exterior soil gas sampling activities identified several petroleum-related
compounds at concentrations above the DEQ Vapor Intrusion SGSLs. No compounds were
detected at concentration above the DEQ Vapor Intrusion SGSLs in the sub-slab soil gas samples
collected within the 609 W. 28th Street Site building. Please note that the chlorinated solvents
PCE and TCE were not detected at a concentration above the DEQ Vapor Intrusion SGSLs in
soil gas samples collected at the Site. This is consistent with the results of Phase II ESA soil gas
sampling activities completed at the Site in February 2022.

To further evaluate potential vapor intrusion risks for the proposed Site buildings, H&H utilized
the DEQ Risk Calculator (January 2023) assuming residential land use scenario for the soil gas
to indoor air vapor intrusion pathway. Hypothetical worst-case risk calculations included the
highest concentration of any compound detected in any soil gas sample collected at the Site
during any sampling event (both February 2022 and April 2023). Risk calculator results indicate
that under a hypothetical worst-case scenario for the soil gas to indoor air vapor intrusion
pathway for residential use, the cumulative LICR is less than the acceptable risk level of 1 x 10-4.
However, the cumulative HI (2.5) for residential use is greater than the acceptable risk level
(1.0).

Methane Gas Sampling
H&H installed and collected subsurface landfill gas measurement from a cluster of ten soil gas
points installed in the southern portion of the Site where low levels of subsurface methane gas
were detected slightly above the atmospheric LEL near the Franklin Avenue right of way.
Subsurface landfill gas measurements were collected from each sampling point on April 17 and
18 and again on May 1 and 2.

Results of the methane gas measurements identified trace levels (up to 0.6% bv) of methane at
concentrations well below the atmospheric LEL and the DEQ Brownfields thresholds for
residential use and methane mitigation. Pressure measurements collected at the Site are within
the accuracy limits for the instrument and are not present at levels that would allow for
subsurface methane to migrate vertically to the surface at potentially explosive concentrations.

Based on results of the supplemental subsurface landfill gas evaluation, the presence of methane
in Phase II ESA sampling point SG-5 is considered to be anomalous and it likely attributable to
intermittent off gassing of utilities located in the nearby Franklin Avenue right of way

Summary
Results of soil sampling activities indicate that soil disturbed during planned redevelopment can
easily be managed in accordance with a DEQ-approved Environmental Management Plan. In
addition, potential vapor intrusion risks posed by petroleum related compounds detected in soil
gas at the Site can easily be managed through the installation of DEQ-approved passive vapor
intrusion mitigation systems designed to have the capability to be converted to active sub-slab
depressurization systems if warranted.

Subsurface methane gas measurements collected in April and May 2023 confirm that there is not
an on-Site source generating methane at concentrations that would pose a risk for the proposed
residential redevelopment and methane mitigation is not warranted.

PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.

analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely,
Angela D Overcash Senior Project Manager
