Brownfields Assessment Report Former Belmont Dyers
18 Linestowe Drive
Belmont, North Carolina
H&H Job RPH-001
1.0 Introduction
Hart & Hickman, PC (H&H) has prepared this Brownfields Assessment Report for the Former
Belmont Dyers property located at 18 Linestowe Drive in Belmont, North Carolina (Site). A
Site location map is included as Figure 1. The subject Site is comprised of two parcels totaling
approximately 11 acres situated on the western bank of the Catawba River. The Site contains a
vacant office building which is approximately 2,000 square feet and two asphalt paved parking
areas. The remainder of the Site is vacant vegetated land.
Aberfoyle LLC received eligibility into the North Carolina Department of Environmental
Quality (DEQ) Brownfields Program for the Site via a Letter of Eligibility dated January 4,
2017. Aberfoyle LLC subsequently elected to participate in the Brownfields Program
Redevelopment Now Pilot option. This assessment was performed in accordance with the
approved Brownfields Assessment Work Plan Revision 1 (Work Plan) dated May 9, 2017.
The Site is planned to be redeveloped with single-family attached and multi-family residential
units. Based upon the current grading plans, there will be up to approximately two ft of cut soil
in the southwestern portion of the Site, up to approximately four ft of cut soil in the western and
northwestern portions of the Site, and up to approximately eight ft of cut soil in the northeastern
and eastern portions of the Site. The cut soils are planned to be placed in the western, central, far
northern, and far eastern portions of the Site to achieve the desired grades. The Brownfields
assessment activities were conducted to evaluate potential risks associated with future Site
development and included collection of soil samples to evaluate potential soil impacts and
collection of soil vapor samples to evaluate potential vapor intrusion concerns for future Site
buildings.

2.0 Background Information
The Site was developed with a textile mill prior to 1929. At that time, the Site contained a main
production building, a boiler building, an attached warehouse, caustic and sulphuric acid tanks,
gasoline underground storage tanks (USTs), a detached warehouse, and the current office
building. Two railroad spurs serviced the Site’s operations until the mid-1960s. An attached dye
house addition was completed by 1965. Former textile operations at the Site consisted of yarn
mercerizing, bleaching, and dyeing. The Site was occupied by the Belmont Processing Company
until the mid-1940s, when Aberfoyle Manufacturing Company took over operations at the Site.
The Site was operated by Belmont Dyers Company from the mid-1970s until 2003. During this
time period, Michelle Textiles also operated in a portion of the building. The former mill
buildings were razed beginning in mid-2007, and the Site has remained vacant since that time.
Soil and groundwater assessment have been conducted at the Site from 1991 to the present.
Assessment and remediation are currently being conducted by the Remediating Party Meridian
Specialty Yarn Group, Inc. (Meridian) pursuant to a voluntary Administrative Agreement (AA)
with the DEQ Inactive Hazardous Sites Branch (IHSB) Registered Environmental Consultant
(REC) program. Currently, a Remedial Investigation (RI) is being performed to define the extent
of compounds in environmental media.
Results of groundwater assessment indicate that groundwater impacts (primarily
tetrachloroethylene or PCE) are present in the central, southern, and eastern portions of the Site
at concentrations exceeding the 15A North Carolina Administrative Code 02L.0202
Groundwater Quality Standards (2L Standards). Analytical results of the most recent
groundwater sampling event conducted in March 2016 indicated concentrations of PCE, 1,2,4-
trichlorobenzene, and 1,4-dichlorobenzene exceeding DEQ Division of Waste Management
(DWM) Residential and Non-Residential Vapor Intrusion Groundwater Screening Levels
(GWSLs) in the southern and eastern portions of the Site.

S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
Low levels of “total pesticides/polychlorinated biphenyls (PCBs)” were detected in shallow soil
across the Site during the 1991 assessment activities. Soil samples collected at the Site have not
been analyzed for pesticides/PCBs since the 1991 assessment. Additionally, soil analytical results
indicated total petroleum hydrocarbons – diesel range organics (TPH-DRO) were detected in 11
soil borings advanced in the vicinity of the former aboveground storage tanks (ASTs) at
concentrations ranging from 10.9 mg/kg to 9,970 mg/kg during the 1991 assessment activities.
Only four of the 11 soil samples contained TPH-DRO above the current DEQ Action Level of
100 mg/kg.
H&H conducted limited soil assessment activities at the Site in November 2016. The purpose of
the soil sampling activities was to evaluate if significant soil impacts may be encountered as part
of future redevelopment activities focusing in areas where soil is expected to be cut as part of
future grading activities and to evaluate soil which may be exposed at the surface as a result of
overlying soil removal. The results of our assessment indicated several polycyclic aromatic
hydrocarbons (PAHs) were detected at concentrations exceeding DEQ IHSB Residential
Preliminary Soil Remediation Goals (PSRGs) in a soil boring advanced in the north-central
portion of the Site. Analytical results indicate volatile organic compounds (VOCs) were not
detected in soil at concentrations exceeding PSRGs. Results of the metals analysis indicate that
metals concentrations in the soil samples are consistent with Site-specific and published regional
background levels for North Carolina soil. Additionally, analytical results indicate hexavalent
chromium was not detected in any soil sample at concentrations exceeding laboratory reporting
limits.
As part of the Redevelopment Now Pilot option process, a kick-off/data gap meeting was held at
the DEQ office in Raleigh, NC on February 28, 2017 to discuss prior Site history, proposed
redevelopment plans, previous assessment results, data gaps, and the proposed schedule for
completing the Brownfields Agreement. Prior to the meeting, a Brownfields Information
Package was submitted to DEQ Brownfields for review. In addition, Brownfields Program
personnel met with H&H at the Site on January 18, 2017. Following the January 18, 2017 Site
visit and the February 28, 2017 kick-off/data gap meeting, the Brownfields Program requested
4
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
additional soil sampling to address the reported previous total pesticides/PCB detections in soil
at the Site and to determine if the pesticides/PCBs are compounds of potential concern at the
Site. Additionally, DEQ subsequently requested soil gas sampling to address potential vapor
intrusion concerns associated with future Site development in the southern and southeastern
portions of the Site where groundwater impacts are present. As discussed with DEQ, other
potential data gaps will be addressed by conducting post-construction soil sampling and
monitoring for potential USTs as part of construction activities.

3.0 Assessment Activities
The assessment activities were performed in general accordance with DEQ - IHSB Guidelines
for Assessment and Cleanup dated October 2015, the DEQ DWM Vapor Intrusion Guidance
dated April 2014, and most recent version of the US Environmental Protection Agency (EPA)
Region IV Science and Ecosystem Support (SESD) Field Branches Quality System and
Technical Procedures guidance.
H&H conducted the Brownfields assessment activities at the Site on May 16, 2017. A
discussion of the methods, analytical results, and conclusions of the Brownfields assessment
activities are provided in the following sections.
3.1 Soil Assessment
To evaluate soil which may be cut and used for fill on-site, H&H advanced nine additional soil
borings at the Site. The soil borings were advanced to the anticipated maximum cut depth at
each boring location.
A summary of the soil boring locations is presented below:
• Soil borings HHSB-1 through HHSB-6 were located in cut areas near former building
exterior walls in the event that pesticide use may have occurred in the area of the
previous Site buildings.
• Soil borings HHSB-7 and HHSB-8 were located in cut areas where previous soil samples
indicated the presence of total pesticides/PCBs during the 1991 assessment activities.
• Soil boring HHSB-9 was located in a cut area in the eastern portion of the Site.
6
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
The soil borings were advanced utilizing a decontaminated stainless-steel hand auger. During
boring advancement, soil cuttings were described for lithologic purposes, inspected for the
presence of staining and odors, and field-screened for the presence of organic vapors with a
calibrated photo-ionization detector (PID). Based upon the field screening, H&H selected one
soil sample from each soil boring location for laboratory analysis. Boring logs with lithologic
descriptions and field screening results are provided in Appendix A.
Upon collection, the soil samples were placed directly into 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 shipped via overnight courier to Con-Test
Analytical Laboratory (Con-Test), a North Carolina-certified laboratory, under chain-of-custody
protocol for analysis of pesticides by EPA Method 8081 and PCBs by EPA Method 8082.
Additionally, the sample from soil boring HHSB-5 was analyzed for SVOCs by EPA Method
8270 and Resource Conservation and Recovery Act (RCRA) metals by EPA Method 6020.
Following sample collection, the soil borings were properly abandoned and the boring locations
were recorded using a sub-meter GPS unit.
3.2 Soil Gas Assessment
To evaluate the potential for vapor intrusion associated with future Site buildings, H&H installed
and sampled five temporary subsurface soil gas monitoring points (HHSG-1 through HHSG-5)
in the eastern, southeastern, and southern portions of the Site where groundwater impacts are
present and proposed Site buildings will be located. The temporary subsurface soil gas
monitoring points were installed and sampled in general accordance with the DEQ DWM Vapor
Intrusion Guidance dated April 2014 and as described below. The soil gas sample locations and
the proposed building footprints are depicted on Figure 3.
The soil gas monitoring points were installed utilizing a stainless-steel hand auger to advance the
borings to approximately 8 ft below ground surface (bgs). A stainless-steel screen point fitted
7
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
with ¼-inch diameter Teflon® tubing was then advanced within the borehole to approximately 10
ft bgs using an AMS soil gas probe kit. Filter sand was placed around the annular space of the
sample point and extended to approximately 6-inches above the bottom of the boring. The
sampling points was completed by placing hydrated bentonite from the top of the filter sand to
the ground surface.
Prior to sampling, a leak check was conducted at each soil gas monitoring point by constructing
a shroud around the monitoring point and flooding the air within the shroud with helium gas.
Using a syringe, a sample was collected from the gas in the shroud into a Tedlar® bag and
analyzed for helium concentrations using a helium gas detector. Vapor from the monitoring
point was purged and sampled outside of the shroud into a separate Tedlar® bag and analyzed
using the helium gas detector to ensure that helium concentrations were less than 5% of the
concentration measured within the shroud.
Following successful field leak checks, the soil gas samples were collected into six-liter Summa
canisters for laboratory analysis by connecting the Teflon® sample tubing to an airflow regulator
using a brass nut and ferrule assembly to create an air tight seal. The airflow regulator was
calibrated by the laboratory to allow the Summa canisters to fill slowly at a rate not greater than
200 milliliters per minute. Upon completion of sample collection, the air flow regulator was
removed from the Summa canister and the samples were shipped via overnight courier to Con-
Test under chain-of-custody protocol for analysis of VOCs by EPA Method TO-15. The soil gas
monitoring point locations were recorded using a sub-meter GPS unit.
3.3 Quality Assurance/Quality Control
H&H utilized standard quality assurance/quality control (QA/QC) processes during the
Brownfields assessment activities. Non-dedicated sampling equipment, including the hand
auger, was decontaminated using Liquinox® detergent and deionized water prior to and between
each sampling location. H&H wore nitrile gloves while handling samples, and the soil gas
monitoring points were installed utilizing dedicated stainless-steel screen points and Teflon®
8
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
tubing. Soil samples were collected in laboratory-provided containers and placed on ice
immediately after collection.
For field and laboratory QA/QC purposes, H&H collected one duplicate soil sample from boring
HHSB-3 and one duplicate soil gas sample from soil gas monitoring point HHSG-4. The
duplicate samples were analyzed for the same compounds as the parent samples.
Prior to soil gas sample collection, H&H conducted a five-minute soil gas sampling system shut
in test for each sample to verify an airtight seal between the Summa canister and airflow
regulator.
3.4 Boring Abandonment and Investigation Derived Waste
Upon completion of the soil and soil gas sampling activities, H&H abandoned the borings with
soil cuttings and/or bentonite. No significant soil impacts were observed during field screening
and sampling activities. Therefore, investigation derived waste (IDW) soil cuttings were placed
back into the soil boring at each location.

4.0 Assessment Results
The results of analysis of the soil samples are summarized in Table 1, and the results of analysis
of the soil gas samples are summarized in Table 2. Laboratory analytical data reports and chain-
of-custody records are included in Appendix B.
4.1 Soil Results
The soil sample analytical results were compared to the DEQ IHSB Residential PSRGs dated
October 2016. Metal concentrations were also compared to Site specific background levels and
regional background levels for North Carolina soils as published in Elements in North American
Soils by Dragun and Chekiri (2005).
The laboratory analytical results indicate the metal arsenic was detected in soil boring HHSB-5
at a concentration of 2.6 mg/kg, which exceeds the Residential PSRG of 0.68 mg/kg, but is
within the range of regional background levels of arsenic. The previous Site background sample
was not analyzed for arsenic. HHSB-5 was located in the southeastern portion of the Site. No
other metals were detected at concentrations above PSRGs. Total chromium does not have a
PSRG, but the detected concentration in HHSB-5 was below the Site background concentration.
Additionally, the results of analysis of the soil samples indicate that the organochlorine pesticide
(OCP) hexachlorobenzene was detected in two soil borings (HHSB-2 and HHSB-6) at estimated
concentrations above the laboratory method detection limit, but below PSRGs.
SVOCs and PCBs were not detected in any of the soil samples.
4.2 Soil Gas Results
Laboratory analytical results of the soil gas samples were compared to the DEQ DWM
10
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
Residential Soil Gas Screening Levels (SGSLs) dated March 2016. These screening levels are
very conservative and based upon a Lifetime Incremental Cancer Risk (LICR) of 1 x 10-5 for
potential carcinogenic effects and/or a Hazard Index (HI) of 0.2 for potential non-carcinogenic
effects. Vapor intrusion mitigation for occupied residential structures is not typically considered
unless the LICR exceeds the acceptable risk range of 1 x 10-4 to 1 x 10-6 for potential
carcinogenic effects and a HI of 1 for potential non-carcinogenic effects.
Laboratory analytical results indicate the presence of several VOCs above laboratory reporting
limits. The chlorinated solvent PCE, and several petroleum-related VOCs including
ethylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and xylenes (total), were
detected in every soil gas sample. Of the compounds detected, only two compounds were
detected at concentrations exceeding Residential SGSLs. PCE was detected at concentrations
above the Residential SGSL (278 µg/m3) in soil gas samples HHSG-2 (320 µg/m3), HHSG-4
(16,000 µg/m3), and HHSG-5 (1,900 µg/m3) located in the far southern and southeastern portion
of the Site. Additionally, 1,2,4-trimethylbenzene was detected in soil gas sample HHSG-5 at a
concentration of 85 µg/m3, which exceeds the Residential SGSL of 48.7 µg/m3. No other
compounds were detected at concentrations above the Residential SGSLs.
4.3 Soil Gas Sample Risk Calculations
To further evaluate the detected compounds, H&H input the concentrations of the compounds in
each sample into the DEQ Risk Calculator (August 2016 Version) to calculate cumulative
potential carcinogenic and non-carcinogenic risks for the five soil gas samples. Copies of the
calculations are provided in Appendix C. A summary of the calculated LICRs and HIs for each
sample is provided below:
Sample ID Sample Location Calculated LICR Calculated HI
HHSG-1 east 2.70E-07 0.021
HHSG-2 southeast 2.30E-06 0.33
HHSG-3 southeast 1.70E-06 0.14
11
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
HHSG-4 south 4.50E-05 12
HHSG-5 south 1.70E-05 1.8
As indicated above, all of the calculated LICRs were within the acceptable risk range of 1 x10-4
to 1 x 10-6. The calculated HIs were all less than 1 except for soil gas samples HHSG-4 and
HHSG-5, collected from the far southern portion of the Site.
4.4 Quality Assurance/Quality Control
The results of analysis of the soil samples indicate no compounds were detected above laboratory
method detection limits in soil sample HHSB-3 or its duplicate. The results of analysis of the
soil gas samples indicate good correlation between the data for the HHSG-4 sample and its
duplicate. The data for the soil duplicate sample is summarized in Table 1, and the data for the
soil gas duplicate sample is summarized in Table 2.
The results of the five-minute shut in test indicated no change in vacuum pressure in any of the
Summa canisters. The results of the five-minute shut in test are summarized in Table 3.

5.0 Summary and Conclusions
H&H completed Brownfields assessment activities at the Former Belmont Dyers Brownfields
site located at 18 Linestowe Drive in Belmont, North Carolina. The Brownfields assessment
activities were conducted to evaluate the risk associated with future Site development including
the potential for vapor intrusion. The Brownfields assessment activities included the collection
of nine soil samples and five soil gas samples for laboratory analysis. Based on the results of the
assessment activities, H&H concludes the following:
Soil
• The analytical results of the soil samples indicate no SVOCs, PCBs, or pesticides were
detected above Residential PSRGs. One metal, arsenic, was detected at a concentration
slightly above the Residential PSRG in the southeastern portion of the Site at a depth of
4-6 ft bgs. However, note that the arsenic detection is within the published range of
regional background levels for North Carolina soils. As such, the arsenic detection is
likely naturally occurring and not the result of historical Site activities.
Soil Gas
• The analytical results of the soil gas samples indicate the presence of two compounds at
concentrations exceeding Residential SGSLs. PCE was detected at concentrations above
the Residential SGSL in the far southern and southeastern portions of the Site (HHSG-4
and HHSG-5). Additionally, 1,2,4-trimethylbenzene was detected in sample HHSG-5
located in the far southern portion of the Site at a concentration above the Residential
SGSL. No other compounds were detected at concentrations above the Residential
SGSLs. The results of the cumulative risk calculations indicate that all of the calculated
LICRs were within the acceptable risk range of 1 x 10-4 to 1 x 10-6. The calculated HIs
were all less than 1 except for soil gas samples HHSG-4 and HHSG-5, collected from the
far southern portion of the Site.
13
S:\AAA-Master Projects\Ralph Falls (RPH)\Report\BF Assessment Report - Former Belmont Dyers.doc
Based upon the results of our activities, there is no evidence of impacted soil at the Site which
would need to be addressed during Site redevelopment or would pose a significant risk to future
residences. The Environmental Management Plan will address potential unknown soil
conditions which could be encountered during Site development as well as post-construction
sampling. The soil gas results indicate vapor mitigation controls appear warranted for future
buildings in the far southern portion of the Site.
