1.0 Introduction

On behalf of The City of Lexington (the Prospective Developer or PD), Hart & Hickman, PC
(H&H) has prepared this report to document vapor intrusion assessment activities completed at
the Lexington Home Brands Plant #1 Brownfields property (Brownfields Project No. 10054-06-
029) located at 411 South Salisbury Street, Lexington, Davidson County, North Carolina (subject
Site or Site). The Site consists of nine parcels of land that total approximately 20.5 acres and
historically operated as a furniture manufacturer dating back to the early 1900s. A Brownfields
Agreement (BFA) for the Site was recorded on April 13, 2016. A Site location map is included
as Figure 1.

Future redevelopment plans at the Site could potentially include modifications to existing
structures located on PIN 6725-02-75-7565 and PIN 6725-02-85-1844 and construction of a
passenger rail station on PIN 6725-02-85-3701 and a small area on the northeastern portion of
PIN 6725-04-74-2825. The western portion of PIN 6725-04-74-2825 is currently being leased to
Lexington Home Brands who have performed warehousing since 2007. With the exception of
Lexington Home Brands, redevelopment plans for parcels with existing structures are currently
in the early conceptual stages but could possibly include retail uses and/or an agricultural
research center with laboratory research. Due to the infancy of the redevelopment planning
process for these parcels, potential structural vapor intrusion should be evaluated at a future date,
if warranted.

Current redevelopment plans at the Site include modifications to the approximately 33,500
square foot (sq ft) existing Bull City Ciderworks brewery/taproom facility (Davidson County
Parcel Identification Number [PIN] 6725-02-75-3197) located at 599 S. Salisbury St. In
addition, the approximately 10,110 sq ft existing building located at 401 S. Railroad Street (PIN

6725-02-75-6185) has been recently upfitted to house the new Goose & the Monkey Brewhouse.
Specifically, proposed redevelopment plans for Bull City Ciderworks, which is owned by Cider
Bros LLC as of December 20, 2019, include upfit of the current taproom to a conditioned retail
space, modifications to the existing warehouse to include new roll-up doors and ventilation
equipment, and expansion into the adjacent vacant structure to the east for the purpose of
constructing an outdoor seating area. Remaining structures on the Bull City Ciderworks parcel
will be demolished for future parking. Redevelopment plans for the Goose & the Monkey
Brewhouse, which is owned by Goose and the Monkey Brewhouse Holdings LLC as of March
17, 2020, included upfit of the existing structure for a brewery/taproom and construction of an
outdoor seating area and parking areas. A Site map showing existing and proposed tenant
occupancy information is included as Figure 2.

1.1 Previous Assessment Activities
In 2009, H&H conducted assessment activities to investigate areas of potential environmental
concern relative to historical operations. These areas included: a former finishing plant,
paint/varnish storage and mixing areas, and a boiler room (Study Area 1); a former 550-gallon
gasoline underground storage tank (UST) (Study Area 2 – general vicinity of the Goose & The
Monkey Brewhouse); and a former block storage building, wood processing area, kilns, and a
former gasoline UST (Study Area 3 – east of Bull City Ciderworks).

Results of the Study Area 1 assessment indicated impacts of petroleum related compounds above
regulatory screening criteria in several soil and groundwater samples. This portion of the
Brownfields property was redeveloped as an amphitheater and soil and groundwater impacts
were managed under a North Carolina Department of Environmental Quality (DEQ) approved
Environmental Management Plan (EMP) dated September 29, 2016.

Results of the Study Area 2 assessment indicated impacts of petroleum related compounds above
regulatory screening criteria in groundwater sample SB-27 collected near the former gasoline
UST (Figure 2). The petroleum release received a notice of No Further Action on January 3,
2005 following recording of a Notice of Residual Petroleum. However, to evaluate the potential
3
\\hhfs01\MasterFiles\AAA-Master Projects\City of Lexington - CLX\CLX-003\VI Assessment Report - Bull City + GMB\Final to DEQ\Brownfields Assessment Report_BPN 10054-06-029_4-15-2020.doc
for structural vapor intrusion into the Goose & the Monkey Brewhouse, H&H utilized Study
Area 2 groundwater results and the May 2019 DEQ Risk Calculator. Results of the groundwater
to indoor air risk evaluation indicated exceedances of acceptable non-residential risk levels
(cumulative lifetime incremental cancer risk [LICR] threshold of 1 x 10-4 and cumulative
non-carcinogenic hazard index [HI] threshold of 1).

Results of the Study Area 3 assessment did not indicate impacts of constituents of concern above
regulatory screening criteria. However, portions of the Bull City Ciderworks facility are located
within approximately 100 ft of potential groundwater impacts associated with Study Area 2.

Consistent with the March 2018 DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance document and the BFA’s Land Use Restriction (LUR) No. 5, H&H has conducted this
Brownfields assessment to evaluate the potential for structural vapor intrusion risk into the Bull
City Ciderworks and the Goose & the Monkey Brewhouse buildings. H&H conducted the
assessment in general accordance with the DEQ approved Brownfields Assessment Work Plan –
Revision 1 (Work Plan), dated October 25, 2019. A summary of Brownfields assessment
activities conducted is provided in the following sections.

2.0 Vapor Intrusion Assessment Activities

On October 16 and 17, 2019, H&H completed vapor intrusion assessment activities at the Site to
evaluate the potential for structural vapor intrusion into the existing Bull City Ciderworks and
the Goose & the Monkey Brewhouse buildings. 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 assessment activities were performed in general accordance with the DEQ approved Work
Plan, the DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup
(Guidelines) dated October 2015 and January 2020, the DEQ DWM Vapor Intrusion Guidance
(VI Guidance) dated March 2018, and most recent versions of the U.S. Environmental Protection
Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches
Quality System and Technical Procedures guidance.

As part of assessment activities, two sub-slab soil gas samples (SG-1 and SG-2) were collected
from the Goose & the Monkey Brewhouse building and five sub-slab soil gas samples (SG-3
through SG-7) were collected from the Bull City Ciderworks building. In addition, seven indoor
air samples (IA-1 through IA-7) were collected in areas co-located with the sub-slab soil gas
samples and placed on hold pending sub-slab soil gas sample analytical results. Note that based
on sub-slab soil gas analytical results (see Section 2.2), indoor air samples were not analyzed per
the DEQ approved Work Plan. The sub-slab soil gas locations (denoted by SG nomenclature)
are shown in Figure 2.

2.1 Sub-Slab Soil Gas Sampling Activities
The sub-slab soil gas sample points were installed by utilizing a hammer drill and a
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.
5
\\hhfs01\MasterFiles\AAA-Master Projects\City of Lexington - CLX\CLX-003\VI Assessment Report - Bull City + GMB\Final to DEQ\Brownfields Assessment Report_BPN 10054-06-029_4-15-2020.doc
Following concrete borehole advancement, loose concrete cuttings were removed from the
boring. A Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone
sleeve) was seated in the borehole using an installation/extraction tool and hammer. The vapor
pins were installed as flush-mount sample points capable of being secured with a stainless-steel
cover that screws onto the sampling point and is seated within the pilot hole annulus. The vapor
pin sampling points were allowed at least two hours for equilibration after installation before
sampling was conducted.

A sampling train for each point was constructed using a Teflon® tubing, disposable
fittings/valves, and a laboratory-supplied 1.4-liter stainless steel Summa sample canister. Prior
to sampling, a leak check was conducted at the soil gas monitoring points by constructing a
shroud around the entire monitoring point and sampling train, and flooding the air within the
shroud with helium gas. Helium concentrations inside the shroud were measured using a helium
gas detector. Using a syringe and disposable valves/fittings, the Teflon tubing and sampling
train was purged of approximately three sample volumes. Following purging, a sample was
collected from the sample tubing outside the shroud into a Tedlar® bag and analyzed using the
helium gas detector to ensure that helium concentrations were less than 10% of the helium
concentrations in the shroud.

Following a successful leak check, the intake valve of the canister was fully opened to begin
collection of the sub-slab vapor sample. The airflow regulator for each cannister was pre-set by
the laboratory to regulate the vapor intake rate to approximately 200 milliliters per minute.
Vacuum readings on the Summa canister were recorded prior to and following the approximately
ten-minute sampling period to ensure adequate sample volume was collected. Per laboratory
standard operating procedures, a vacuum was maintained within the canisters at the conclusion
of the sampling event.

H&H attempted to collect a duplicate sub-slab soil gas sample from the SG-5 parent sample.
However, the laboratory-supplied flow controller and fittings did not pass the helium leak check
conducted prior to sampling and the sample was therefore omitted. Note the SG-5 parent sample
successfully passed a leak check after removal of the attempted duplicate sample cannister/flow

\\hhfs01\MasterFiles\AAA-Master Projects\City of Lexington - CLX\CLX-003\VI Assessment Report - Bull City + GMB\Final to DEQ\Brownfields Assessment Report_BPN 10054-06-029_4-15-2020.doc
controller.

After sample collection, the Summa canister’s valves were closed prior to the regulator being
disconnected from the canister and the Summa canisters were then placed in laboratory supplied
shipping containers, properly labeled, and shipped under standard chain-of-custody protocols to
Enthalpy Analytical, LLC (Enthalpy) for analysis of volatile organic compounds (VOCs) by
EPA Method TO-15. The TO-15 analysis was conducted using method detection limits below
DEQ Residential Soil Gas Screening Levels (SGSLs).

Upon completion of sampling activities, each sub-slab vapor boring was secured with a stainless-
steel cover that screws onto the sampling point and is seated within the pilot hole annulus.

2.2 Sub-Slab Soil Gas Sample Analytical Results

Results of sub-slab soil gas analyses are summarized in Table 1. The laboratory analytical report
and chain of custody record are provided in Appendix A. Sub-slab soil gas sample analytical
results were compared to the February 2018 DEQ Residential and Non-Residential SGSLs.

Laboratory analytical results indicate that VOCs were detected in each sub-slab soil gas sample
at concentrations above the laboratory method detection limits. However, no compounds were
detected at concentrations that exceed their respective Non-Residential SGSLs. Chloroform was
detected in sub-slab soil gas sample SG-1 (Goose & the Monkey Brewhouse) at a concentration
of 41.8 micrograms per cubic meter [µg/m3], which is slightly above the Residential SGSL of
41.0 µg/m3. No other compounds were detected at concentrations that exceed Residential
SGSLs.

2.3 Evaluation of Vapor Intrusion Assessment Results

Consistent with proposed redevelopment at the Site, H&H utilized the December 2019 DEQ
Risk Calculator to calculate both non-residential and residential cumulative risks to further
evaluate potential structural vapor intrusion risks for each of the on-Site buildings.
7
\\hhfs01\MasterFiles\AAA-Master Projects\City of Lexington - CLX\CLX-003\VI Assessment Report - Bull City + GMB\Final to DEQ\Brownfields Assessment Report_BPN 10054-06-029_4-15-2020.doc

Cumulative risk calculations were performed using the highest concentration of each compound
detected above the laboratory method detection limit from the soil gas samples collected in each
building as a worst-case scenario. Therefore, samples SG-1 and SG-2 were used to calculate the
cumulative risk for the Goose & the Monkey Brewhouse facility and samples SG-3 through SG-
7 were used to calculate the cumulative risk for the Bull City Ciderworks facility. The
completed risk calculators are provided in Appendix B.

For the Bull City Ciderworks facility, the results of non-residential risk calculations indicated a
cumulative LICR of 5.1 x 10-8 and a cumulative HI of 0.0044. The results of risk calculations
for a resident scenario indicated a cumulative LICR of 7.7 x 10-7 and a cumulative HI of 0.056.

For the Goose & the Monkey Brewhouse, the results of non-residential risk calculations
indicated a cumulative LICR of 9.1 x 10-7 and a cumulative HI of 0.0070. The results of risk
calculations for a resident scenario indicated a cumulative LICR of 1.2 x 10-5 and a cumulative
HI of 0.089.

The above referenced calculated cumulative risk values for both facilities do not exceed a LICR
of 1 x 10-4 or a HI of 1 for the soil gas to indoor air vapor intrusion pathway for residential and
non-residential land use scenarios. Based on evaluation of the December 2019 DEQ risk
calculator results, there is no evidence of a vapor intrusion concern for the Bull City Ciderworks
and the Goose & the Monkey Brewhouse buildings.

3.0 Summary and Conclusions

H&H has completed Brownfields vapor intrusion assessment activities at the Lexington Home
Brands Plant #1 Brownfields property located in Lexington, North Carolina. The assessment
activities were conducted in general accordance with the DEQ Brownfields approved Work Plan
dated October 25, 2019 and the BFA’s LUR No. 5. Brownfields assessment activities included
collection of sub-slab soil gas samples from the Bull City Ciderworks and the Goose & the
Monkey Brewhouse buildings.

With the exception of chloroform in the sub-slab soil gas sample collected from SG-1 in the
Goose & the Monkey Brewhouse building, results of soil vapor assessment activities did not
identify any additional compounds at concentrations that exceed the Residential and Non-
Residential SGSLs. In addition, December 2019 DEQ risk calculator results indicate that
calculated cumulative risk values for the soil gas to indoor air vapor intrusion pathway for
residential and non-residential worker scenarios are within the acceptable lifetime incremental
cancer risk of 1 x 10-4 to 1 x 10-6 and less than a hazard index of 1.

In summary, results of soil vapor intrusion assessment activities indicate that structural vapor
intrusion into the Bull City Ciderworks and the Goose & the Monkey Brewhouse buildings does
not pose a significant risk and does not warrant further assessment in accordance with the DEQ
DWM Vapor Intrusion Guidance. Further, vapor mitigation measures do not appear warranted
for these buildings.

Narrative Summary

Enthalpy Analytical Narrative Summary
Company Hart & Hickman - Raleigh Client #CLX-003
Analyst TDD Job #0919-153
Parameters EPA Method TO-15 # Samples 7 Canisters

Custody David Myers received the samples on 10/18/19 after being relinquished
by Hart & Hickman – Raleigh. The samples were received at ambient temperature and in good condition.
Prior to, during, and after analysis, the samples were kept under lock with access only to authorized personnel by Enthalpy Analytical, LLC.
Analysis The samples were analyzed for the client requested TO-15 target
compound list using the analytical procedures in EPA Method TO-15,
Determination of Volatile Organic Compounds (VOCs) In Air Collected
In Specially-Prepared Canisters And Analyzed by Gas
Chromatography/Mass Spectrometry (GC/MS).
Upon receipt, the canister pressures were measured and recorded. The
cans were then pressurized and a dilution ratio was calculated for each (see the Canister and Controller Data Sheet in this report).
All samples were analyzed undiluted. Samples SG-4, SG-5, SG-6 and
SG-7 were analyzed at a subsequent 10-fold dilution to bring ethanol
and/or acetone within the instrument’s calibrated range. Only
compounds that exceeded the instrument’s calibration range in the undiluted analysis have been reported in the diluted analysis.
The Agilent Technologies Model 6890N, Gas Chromatograph "Xavier" (S/N US10721018) equipped with a 5975C VL Mass Selective Detector
(S/N US71215962) and a Restek Rxi-624 Sil MS, 60 m x 0.32 mm x 1.8
µm (S/N 1555499) capillary column was used for these analyses. The samples and standards were introduced directly to the analyzer using an Entech 7200 Preconcentrator
Calibration The associated BFB tune met method acceptance criteria. The initial
calibration (X082919A-TO15) met the 30% RSD criteria. The initial
calibration verification met the 30% recovery criteria. The continuing calibration met the 30% difference criteria. Full calibration data is available upon request.
Chromatographic Conditions
The acquisition method (TO15-SCN2.M) is not included in this report
but is available upon request.

Enthalpy Analytical Narrative Summary
(continued)

QC Notes The BFB tunes associated with this analysis met method acceptance criteria.
All internal standard area responses and retention time criteria were met
for these analyses.
The Laboratory Control Standards (LCS) met 70-130% recovery criteria with allowances.
The Laboratory Duplicates (LD) associated with sample data met the 25% difference acceptance criteria.
There were no target analytes detected in the associated humid blank at concentrations greater than 3 times the MDL.
The samples were analyzed within the 30-day holding time required by the method.
Reporting Notes The LCS was analyzed in duplicate and has been reported as a
Laboratory Duplicate in the Lab QC section of this report.
These analyses met the requirements of the TNI Standard. Any deviations from the requirements of the reference method or TNI Standard have been stated above.
The results presented in this report are representative of the samples as
provided to the laboratory.

General Reporting Notes
The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC data reports, unless specifically noted otherwise.

 Any analysis which refers to the method as “Type” represents a planned deviation from the
reference method. For instance a Hydrogen Sulfide assay from a Tedlar bag would be labeled
as “EPA Method 16-Type” because Tedlar bags are not mentioned as one of the collection
options in EPA Method 16.
 The acronym MDL represents the Minimum Detection Limit. Below this value the laboratory
cannot determine the presence of the analyte of interest reliably.
 The acronym LOQ represents the Limit of Quantification. Below this value the laboratory cannot quantitate the analyte of interest within the criteria of the method.
 The acronym ND following a value indicates a non-detect or analytical result below the MDL.
 The letter J in the Qualifier or Flag column in the results indicates that the value is between
the MDL and the LOQ. The laboratory can positively identify the analyte of interest as
present, but the value should be considered an estimate.
 The letter E in the Qualifier or Flag column indicates an analytical result exceeding 100% of
the highest calibration point. The associated value should be considered as an estimate.
 Sample results are presented ‘as measured’ for single injection methodologies, or an average value if multiple injections are made. If all injections are below the MDL, the sample is considered non-detect and the ND value is presented. If one, but not all, are below the MDL, the MDL value is used for any injections that are below the MDL. For example, if the MDL is 0.500 and LOQ is 1.00, and the instrument measures 0.355, 0.620, and 0.442 - the result reported is the average of 0.500, 0.620, and 0.500 - - - i.e. 0.540 with a J flag.
 When a spike recovery (Bag Spike, Collocated Spike Train, or liquid matrix spike) is being
calculated, the native (unspiked) sample result is used in the calculations, as long as the value
is above the MDL. If a sample is ND, then 0 is used as the native amount (not the MDL
value).
 The acronym DF represents Dilution Factor. This number represents dilution of the sample
during the preparation and/or analysis process. The analytical result taken from a laboratory
instrument is multiplied by the DF to determine the final undiluted sample results.
 The addition of MS to the Sample ID represents a Matrix Spike. An aliquot of an actual sample is spiked with a known amount of analyte so that a percent recovery value can be determined. The MS analysis indicates what effect the sample matrix may have on the target analyte, i.e. whether or not anything in the sample matrix interferes with the analysis of the analyte(s).

General Reporting Notes
(continued)
 The addition of MSD to the Sample ID represents a Matrix Spike Duplicate. Prepared in the same manner as a MS, the use of duplicate matrix spikes allows further confirmation of laboratory quality by showing the consistency of results gained by performing the same steps multiple times.
 The addition of LD to the Sample ID represents a Laboratory Duplicate. The analyst prepares
an additional aliquot of sample for testing and the results of the duplicate analysis are
compared to the initial result. The result should have a difference value of within 10% of the
initial result (if the results of the original analysis are greater than the LOQ).
 The addition of AD to the Sample ID represents an Alternate Dilution. The analyst prepares an
additional aliquot at a different dilution factor (usually double the initial factor). This analysis
helps confirm that no additional compound is present and coeluting or sharing absorbance with
the analyte of interest, as they would have a different response/absorbance than the analyte of
interest.
 The Sample ID LCS represents a Laboratory Control Sample. Clean matrix, similar to the client sample matrix, prepared and analyzed by the laboratory using the same reagents, spiking standards and procedures used for the client samples. The LCS is used to assess the control of the laboratory’s analytical system. Whenever spikes are prepared for our client projects, two spikes are retained as LCSs. The LCSs are labeled with the associated project number and kept in-house at the appropriate temperature conditions. When the project samples are received for analysis, the LCSs are analyzed to confirm that the analyte could be recovered from the media, separate from the samples which were used on the project and which may have been affected by source matrix, sample collection, and/or sample transport.
 Significant Figures: Where the reported value is much greater than unity (1.00) in the units expressed, the number is rounded to a whole number of units, rather than to 3 significant
figures. For example, a value of 10,456.45 ug catch is rounded to 10,456 ug. There are five
significant digits displayed, but no confidence should be placed on more than two significant
digits. In the case of small numbers, generally 3 significant figures are presented, but still only
2 should be used with confidence. Many neat materials are only certified to 3 digits, and as the
mathematically correct final result is always 1 digit less than all its pre-cursors - 2 significant
figures are what are most defensible.
 Manual Integration: The data systems used for processing will flag manually integrated peaks with an “M”. There are several reasons a peak may be manually integrated. These reasons will be identified by the following two letter designations on sample chromatograms, if provided in the report. The peak was not integrated by the software “NI”, the peak was
integrated incorrectly by the software “II” or the wrong peak was integrated by the software “WP”. These codes will accompany the analyst’s manual integration stamp placed next to the compound name on the chromatogram.
