1.0 INTRODUCTION
In accordance with the Generic Quality Assurance Project Plan (QAPP) dated December 17,
2020, the Site Specific QAPP Addendum A-1 (SSQAPP) dated February 8, 2021, and the
Work Plan and Addendum to Site -Specific Quality Assurance Project Plan (Work Plan) dated
June 16, 2022, Mid -Atlantic Associates, Inc. (Mid -Atlantic) has prepared this Addendum to
Limited Environmental Site Assessment Report for the Sonrise Industrial Center site located
at 1200 Henry Street in Roanoke Rapids, North Carolina (the subject site). The Sonrise
Industrial Warehouse site contains the former WestPoint Stevens Rosemary Complex and
consists of nine contiguous parcels (54.13 acres) located between W. 10t" Street to the north,
Roanoke Avenue to the east, and W. 131" Street to the south (Drawings 1 and 2). A
recreational complex containing baseball fields is located to the west of the subject site. The
current owner of the subject site is Sonrise Reclamation, LLC (Sonrise) of Indianola,
Mississippi.
Mid -Atlantic completed a Phase I Environmental Assessment (PESA) on the subject site dated
September 30, 2014. The September 30, 2014 PESA report documented site conditions from a
visit on August 13, 2014. Three textile mills, a finishing plant, fabrication warehouse and
distribution warehouse occupied the site and were referred collectively by the last
owner/occupant (WestPoint Stevens) as the "Rosemary Complex". At the time of the most
recent field activities discussed in this report (June 2022), the subject site was vacant.
The September 30, 2014 PESA report prepared by Mid -Atlantic identified multiple Recognized
Environmental Conditions (RECs) which were investigated as described in the March 7, 2016
Limited Environmental Site Assessment (2016 LSA) and July 8, 2021 Limited Environmental
Site Assessment Report dated (2021 LSA).
Both assessments identified environmental impacts to groundwater including the presence of
chlorinated solvents 1, 1, 1 -Trichloroethane (TCA), perch loroethylene (PCE), and their respective
degradation compounds. The 2021 LSA notes that these compounds have been detected at
concentrations above their respective NC Groundwater Quality Standard (NCGQS), Residential
Vapor Intrusion Screening Levels (VISLs) and/or Non -Residential VISLs at multiple locations.
Historical sampling locations are shown on Drawing 2.
Because multiple residences/receptors are located adjacent to the subject site, the NC
Brownfields Program requested that the groundwater monitoring network at the subject site be
evaluated to confirm groundwater flow conditions at the site. In addition, the NC Brownfields
Program requested that a paired indoor air and sub -slab soil gas sample be collected in a former
machine shop area located inside the former distribution warehouse located adjacent to
monitoring well MW-8.
2.0 SUMMARY OF FIELD ACTIVITIES
To confirm groundwater flow conditions at the subject site and assess indoor air and sub -slab
soil gas, Mid -Atlantic gauged depth to water at the wells comprising the monitoring well
network and collected a paired indoor air and sub -slab soil gas sample in the former machine

shop. The location of the former machine shop was confirmed using signage inside the former
distribution warehouse and photographs collected during the Phase I.
2.1 Groundwater Assessment
Mid -Atlantic personnel surveyed the top of casing (TOC) elevations relative to wells as part
of the 2016 and 2021 LSAs. Prior to measuring depth to groundwater in the monitoring wells,
Mid -Atlantic removed the well caps and allowed groundwater levels to equilibrate for 1-2
hours. Depth to groundwater was measured on June 22, 2022 and groundwater was
encountered at depths ranging from approximately 11 to 30 feet BLS (Table 1). Using the
survey elevations and water level measurements from June 22, 2022 an estimated
groundwater table elevation contour map was prepared for the site and is provided as Drawing
3. As shown, the estimated groundwater flow direction at the site was determined to be
generally to the south-southeast, towards a dry valley shown on the topographic map with
Chockoyotte Creek located further south (Drawing 1).
2.2 Indoor Air Sample Collection
An 8-hour indoor air sample (IA-1) and duplicate (IA-DUP) were collected inside the former
machine shop. The approximate sample location is shown on Drawing 4. The indoor air sample
and duplicate were placed on boxes so the sample was collected approximately four feet above
the ground. The samples were collected in general accordance with the DWM Vapor Intrusion
Guidance dated March 2018 and the aforementioned QAPPs. The samples were collected on
June 22, 2022 using individually -certified 6-liter stainless steel Summa canisters at a maximum
flow rate of 8-10 ml/min. Outdoor temperatures were in the mid-70s (F) at the start of the
sampling and peaked in the mid-90s (F). The skies were mostly sunny and there was a light
breeze. After collection, the indoor air samples were provided to a courier affiliated with Waypoint
under proper chain of custody for analysis. The canisters were analyzed for VOCs in accordance
with EPA Method TO-15.
2.3 Soil Gas Sampling Activities
2.3.1 Vapor Implant Installation Procedures
Following indoor air sample collection, Mid -Atlantic installed and sampled an interior sub -slab
soil gas sampling point and duplicate (SG-9 and SG-DUP) to evaluate soil gas quality beneath
the former machine shop. To create a sub -slab sampling port, a rotary -impact drill equipped with
a decontaminated spline drill bit was utilized to drill a 5/8-inch diameter hole through the concrete
slabs. The concrete slab was approximately 6 to 8 inches thick. Mid -Atlantic observed what
appeared to be soil after puncturing through the concrete slab. Upon completion, a vapor
sampling probe was established using a new "Vapor Pin TM" which utilizes a brass barb fitting
with a silicone sleeve to create a seal with the concrete when inserted using an
installation/extraction tool. The vapor pin was then fitted with'/4-inch outer diameter Teflon -lined
tubing to complete the vapor sampling probe assembly.

2.3.2 Helium Leak Check Procedures
Upon completion of sample point construction activities, the points were purged and a leak
check was performed at each probe location using a plastic shroud, helium gas, and a portable
helium gas detector. A plastic shroud was placed over the entire sampling train of each soil gas
sampling location. Helium was released into the shroud via tubing from the cylinder into the
shroud, and a grab sample was collected by filling a Tedlar bag using the exhaust port of the
purge syringe. Helium was not detected within the Tedlar bag at a concentration exceeding
DEQ's acceptable guideline of ten percent of the helium concentration under the plastic shroud
at the sampling locations. As such, leaks were not detected prior to soil gas sample collection.
The results of Mid -Atlantic's helium leak checks at each sample location are as follows:

Note: 1 % = 10,000 PPM
2.3.3 Sample Collection Procedures
Sub -slab soil gas samples SG-9 and SG-DUP were collected using a 1-liter stainless steel
canister at a maximum flow rate of 200 milliliters per minute (ml/min) after performing the helium
leak check. Upon collection, the soil gas samples were provided to a courier affiliated with
Waypoint under proper chain of custody for analysis of VOCs according to EPA Method TO-
15.
3.0 SUMMARY OF LABORATORY TEST RESULTS
The laboratory analytical report and chain -of -custody records for the sub slab soil gas and indoor
air samples collected at the site are provided in Appendix A. Laboratory results from indoor air
and soil gas samples are summarized in Tables 2 and 3, respectively.
3.1 Sub -Slab Soil Gas and Indoor Air Sample Results
Indoor air and sub slab soil gas sample results were compared to the Soil Gas Screening
Levels (SGSLs) and Indoor Air Screening Levels (IASLs) January 2022 tables respectively.
As summarized on Table 2, two constituents, chloroform and naphthalene, were detected
above their respective Residential and Non -Residential IASLs in indoor air at estimated
concentrations. Other indoor air constituents were detected above their MDLs, but not at
concentrations above their respective Residential/Non-Residential IASLs.

As summarized in Table 3, soil gas constituents were not detected at concentrations
exceeding Residential and/or Non -Residential SGSLs.
3.2 Risk Evaluation Methodology and Results
The cumulative risk is calculated by entering the maximum concentrations of all contaminants
detected at each established exposure unit (EU) into the DEQ Risk Calculator. An EU is a
defined area of a site represented by a specific set of land use(s), receptors, contaminant
concentrations, and exposure pathways.' The soil gas sample and indoor air sample (and their
respective duplicates) were treated as their own EU. Information regarding the specific EUs is
described in the table below:
SG-9 and SG-DUP Machine Shop Soil Gas
IA-1 and IA-DUP Machine Shop Indoor Air
The DEQ Risk Calculator determines the cancer risk sum for all carcinogens and the cumulative
hazard index for all non -carcinogens. The DWM allows a maximum cancer risk sum for all
carcinogens of 1.0E-04 and a maximum non -carcinogenic hazard index of 1.0E+00. The hazard
index is the sum of the hazard quotient (HQs) calculated for each compound detected. The
NCDEQ risk calculations for the subject site are included in Appendix B. As noted in Section
4.2.5, eight analytes in IA-1 and IA-DUP had MDLs above their respective SGSLs/IASLs. As
such, risk calculations for soil gas and indoor air included the MDL of the analyte in undiluted
samples.
The results of the risk evaluations for IA-1/IA-DUP are summarized on Table 2. Under a
residential exposure scenario, the non -carcinogenic hazard index was above the target value at
1.4E+00 while the target value for the cancer risk sum (1.0E-04) was not exceeded at 6.3E-05.
Under a non-residential exposure scenario, neither the non -carcinogenic hazard index or the
cancer risk sum were exceeded. When the eight compounds with MDLs above their respective
IASLs are not considered in risk calculations, the non -carcinogenic hazard index becomes 1.6E-
05 and the cancer risk sum was 6.6E-01, both of which are below their respective target values
under a residential exposure scenario.
The results of the risk evaluations for soil gas samples are summarized on Table 3. Under a
residential exposure scenario, the non -carcinogenic hazard index was below the target value
(1.0E+00) at 4.1 E-02 and the target value for the cancer risk sum (1.0E-04) was not exceeded
at 1.0E-06. Under a non-residential exposure scenario, neither the non -carcinogenic hazard
index or the cancer risk sum were exceeded. Risk calculations are provided in Appendix B.

3.4 Summary and Discussion
Depth to groundwater measurements collected as part of this assessment and the estimated
groundwater flow direction are consistent with the findings of the 2016 and 2021 LSAs with a
dominant southward component to groundwater flow. Based on the analytical results from
soil gas and indoor air testing, there is no evidence of a release to the environment originating
at the machine shop or an exposure risk to vapors in a non-residential scenario. However,
historical groundwater sampling at well MW-8 (located directly downgradient of the machine
shop) in 2016 exhibited a concentration of PCE just below its NC Groundwater Quality
Standard (0.7 ug/L versus a detection of 0.68 ug/L).
4.0 QUALITY ASSURANCE
The QAPP and the SSQAPP set forth the procedures and methods for data collection, and
defined the specific procedures and adjustments necessary to maintain data quality to support
the project decision. This Addendum to Limited Environmental Site Assessment (ESA) requires
both field and laboratory checks to monitor conformance to project quality limits.
4.1 Property -Specific Corrective Actions
The investigation field methods were reviewed during the data verification audit discussed in the
next paragraph. The field methods used were consistent with the EPAs guidelines included in
Appendices D and E of the QAPP (note that the SSQAPP referenced the QAPP for field
procedures) with the following exceptions:
• Field equipment was calibrated by the rental equipment supplier prior to use by Mid -
Atlantic personnel.
Data verification and data validation audits were completed by Mid -Atlantic before this report
was prepared. In addition to the items listed above, the following deficiencies were discovered
that were related to the laboratory testing program:
The method detection limits for the indoor air exceeded the Residential and/or Non -
Residential IASLs for eight indoor air constituents not detected in indoor air. These
include benzyl chloride, bromodichloromethane, 1,3-butadiene, 1,2-dichloroethane, 1,2-
dibromoethane, hexachlorobutadiene, 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane.
4.2 Quality Control Parameters
To assess whether quality assurance objectives for this project have been achieved, the
following QC parameters were considered: precision, accuracy, representativeness,
comparability, completeness and sensitivity.
Mid Atlantic

Sonrise Industrial Center Page 6
1200 Henry Street
Roanoke Rapids, North Carolina
4.2.1 Precision and Accuracy
As described in the QAPP, precision is evaluated using the relative percent difference (RPD)
between an actual sample and a duplicate sample. In accordance with the SSQAPP Addendum,
a duplicate indoor air sample and a sub -slab soil gas sample were collected during field
activities. A comparison of the detected concentrations for the primary sample and the
associated duplicate sample was made to evaluate the reproducibility of the sample results
based on the laboratory analysis and sample collection and transportation procedures. The
variability of the results for the primary and duplicates sample were evaluated by calculating the
RPD and percent ratio for each analyte among the duplicate pair using the formula below
RPD = [(x,-xjlx]X100% Where:
x, = concentration of sample 1 of pair,
x2 = concentration of sample 2 of pair, and
x = average of sample 1 and sample 2.
RPD percentages <35% indicate "good/acceptable" variability, a %RPD >35% but < 50%
indicated that the variability was "slightly high", and a %RPD >50% indicated a "high" degree of
variability.
Soil Gas/Indoor Air Samples
Of the 13 indoor air constituents detected in primary indoor air sample IA-1 and/or its duplicate,
IA-DUP, three were detected above their respective RLs in both samples (acetone,
dichlorodifluoromethane, and tetrachloroethylene). Precision was determined to be acceptable
for the indoor air constituents detected in IA-1 and IA-DUP (Table 4).
Of the 26 indoor air constituents detected in primary soil gas sample SG-9 and/or its duplicate,
SG-DUP, nine were detected above their respective RLs in both samples (acetone, 2-butanone,
dichlorodifluoromethane, heptane, isopropanol, propene, tetrachloroethylene, toluene, and m&p
xylene). Precision was determined to be acceptable for six of the compounds, slightly high for
two of the compounds (2-butanone and heptane), and high for propene (Table 5).
Accu racy
Accuracy is evaluated using a percent recovery measured in spiked and unspiked samples.
Accuracy is a function of the laboratory method, and parameters regarding accuracy are
included in the lab reports provided in Appendix A.
4.2.2 Representativeness
Mid -Atlantic has evaluated the representativeness of the limited ESA activities to document the
degree to which the sample data accurately and precisely represents a characteristic of a

population, parameter variations at a sampling point, or an environmental condition. Review of
field methods and procedures indicated that sample collection, handling and transportation were
conducted in accordance with the QAPP and SSQAPP. Review of analytical results indicates
that the analytical data is generally uniform and consistent between sampling points.
4.2.3 Completeness
Soil Gas/Indoor Air: A total of 4 soil gas/indoor air samples were submitted for analysis for
VOCs by EPA Compendium Method TO-15 in accordance with the Work Plan. Completeness
for the testing specified in the Work Plan was 100% for VOCs.
4.2.4 Comparability
To produce comparable data, the units specified for analytical results obtained during the field
activities are consistent throughout this project. The soil gas and indoor air concentrations used
in the report tables are similar to the units included in the State and EPA action level tables that
are used for comparison. Standardized analytical methods have been used for each parameter.
4.2.5 Sensitivity
Laboratory quantitation limits (the reporting limit and/or MDL) for soil gas and indoor air samples
were sufficient to report concentrations below the action levels in undiluted samples. Exceptions
to this are noted below:
Indoor Air
The method detection limits for the indoor air exceeded the Residential IASLs for eight indoor
air constituents that were not detected. These include benzyl chloride, bromodichloromethane,
1,3-butadiene, 1,2-dibromoethane, 1,2-dichloroethane, hexachlorobutadiene, 1,1,2,2-
tetrachloroethane, and 1,1,2-trichloroethane. One of these compounds, 1,2-dibromoethane, had
an MDL that exceeded its Non -Residential IASL. For the purpose of risk evaluation and
comparison, risk calculations were performed with, and without, the MDLs of the compounds
above.
4.3 Laboratory Data Evaluation
The laboratories completed validation and verification of laboratory processes and data, and
delivered laboratory reports to the Mid -Atlantic Project Manager. The laboratory reports and the
QC information contained therein documents compliance to the QAPP.
The following qualifiers were used by the laboratories in the reports when presenting data for
the samples and QA/QC samples collected by Mid -Atlantic:
"J" — Result is an estimated concentration (J-Flag).
Mid Atlantic

Addendum to Limited Environmental Site Assessment Report July 26, 2022
Sonrise Industrial Center Page 8
1200 Henry Street
Roanoke Rapids, North Carolina
"<" — Not detected at or above the method detection limit (MDL).
Data usability determination is also a part of data evaluation. After data validity has been
assessed, that is, the analytical data has been reviewed and qualifier codes have been applied,
these data were individually identified and assessed for usability. Sample data (both with and
without qualifier codes) may be generally spoken of as either qualitative (Level A), quantitative
(Level B), or unusable. Within any matrix it is likely certain samples may have parameters that
require qualifier codes. A discussion of these qualifier codes for each level is provided below.
4.3.1 Qualitative Data — Level A
Qualitative data are often referred to as Level A data. All screening data is considered Level A
data. Screening data may not be considered as Level B data and cannot be used to make site
management decisions. Data in this level also include "J" coded data. These data are considered
to be an estimated quantity, i.e., a presence or absence value. Data having been given a "J"
code were not automatically classified as qualitative data only; these data were considered as
Level B (quantitative) data depending on bias, and were evaluated on a case by case basis.
Data reported with a "NY code or marked with a "<" symbol can also be classified as Level B
data provided the detection limit was not above an applicable regulatory action level for that
analyte. All analytical data received as part of the analytical package for this site were accepted
as Level A data.
Some results for indoor air analytes with MDLs above applicable action levels and listed as not
detected must be considered as Level A data. These analytes are listed in Section 4.2.5.
4.3.2 Quantitative Data — Level B
Data at this level are referred to as Level B data. Only data meeting all field and analytical data
usability requirements may be classified as Level B data. This means all quality assurance
parameters have been satisfied, including quality control and quality assessment. Only data
that were found to be analytically valid and passed all criteria for Level A were considered for
classification at Level B. These data are considered definitive and may be used for any purpose.
Based on information provided in the laboratory reports, laboratory tests were performed within
the appropriate holding times. Except for items noted in Section 4.3.1, detected analytes in all
samples which were both above the MDL and RL and are accepted as Level B data.
In reviewing the laboratory reports, multiple analytes were reported as detections with "J" data
qualifiers, indicating the reported value is an estimate. These compounds (J value) were
detected above the MDL, but below the RL. The MDL is the lowest concentration at which an
analyte can be detected in a sample by the particular laboratory method used. "Detected"
indicates that the analyte can be distinguished from the blank with reasonable certainty. The
RL is approximately five times the MDL or the lower calibration standard, whichever is higher.
Results above the RL can be distinguished from the blank and fall within applicable standard

curves. For the purposes of this assessment, "J value" qualified data are considered acceptable
for making site management decisions as these data are not the sole determinant of "clean."
These data are accepted as Level B data.
5.0 SUMMARY AND CONCLUSIONS
Sonrise Reclamation, LLC owns the subject property and may sell the property in the future
to a potential buyer. The objective of this assessment was to further assess the historical use
of the subject site and to assess whether contaminants are present at levels that may be an
impediment to future redevelopment. Mid -Atlantic offers the following conclusions based on
the results of this assessment as they pertain to redevelopment:
Groundwater flow below the site is to the south-southeast towards a topographic low
area of the property and a "dry" stream valley that has been backfilled over time on
the Sonrise Industrial Center and the adjacent Panda co -generation facility (Dominion
Power) site. A perennial steam, Chockoyotte Creek, is located approximately 1,500
feet to the south. This groundwater flow direction is consistent with historical
assessments performed at the site.
Soil gas constituents were not detected above their Residential and/or Non -
Residential SGSLs. This suggests that a release has not occurred in the vicinity of
the former machine shop.
Indoor air sample IA-1 and its duplicate (IA-DUP) did not exhibit detectable
constituents at concentrations that exceeded their respective residential or non-
residential IASLs. Because the MDLs for these samples exceeded the IASL for
multiple constituents, a set of risk calculations were performed that included the MDLs
of these compounds (i.e. considered these compounds to be present at their MDLs
as a very conservative measure and compounds reported at estimated
concentrations). With these compounds included at concentrations equal to their
respective MDLs, the cancer risk sum and non -carcinogenic hazard index were
exceeded under a residential scenario, but not in a non-residential scenario. When
these compounds are not assumed present, neither the cancer risk sum or non -
carcinogenic hazard index are exceeded in either scenario.
Based on the data collected to date, it does not appear that contaminants present at the site
pose an unacceptable risk for a non-residential redevelopment/use. Additional assessment,
remedial action, and/or engineering/institutional controls may be necessary to facilitate a
more sensitive use (i.e. residential, etc.). Mid -Atlantic recommends that a copy of this report
be submitted to the NCBP for their review as they prepare the draft Brownfields Agreement
for this site.

Notes:
Note 1 = If duplicate or sample results is less than 5 times the reporting limit (RL), then the comparison is made by the absolute difference (ABS) between results. If ABS is less
than the higher
reporting limit, precision is considered acceptable.
If duplicate or sample result is greater than 5 times the RL, then the comparison is assessed by the RPD (Note 2)
Note 2 = The relative percent difference (RPD) and percent ratio were calculated for each pair (see formulas in column headings). Variability
was evaluated based on % RPD:
Good/Acceptable (<35%), Slightly High (>35% but <50%) and High
(%50).
Note 3 = ABS less than the magnitude of the RL are considered acceptable. ABS within two times the magnitude of the RL are considered "slightly high".
ABS greater than two times the RL are considered "High".
Blank Cells = Consituent not detected, or below the method detection limit (MDL).
NT = Constituent not tested for.
J = Detected, but below the Reporting Limit; therefore, result is an estimated concentration
ND = Constituent not detected above the method detection limit (MDL), which is lower than the reporting limit (RL).
NC - J Value = Variability not determined because one or both results are "estimated" concentrations (J-values) below the reporting limit.
NC - Only 1 = Variability not determined because the analyte was not detected in both the primary and duplicate sample

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic
risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals
are likely not associated with vapor intrusion.
All concentrations are in uQ/m3
