Dear Mr. Ertep:
The Tetra Tech, Inc. (Tetra Tech) Superfund Technical Assessment and Response Team (START)
submits this removal evaluation report summarizing removal site evaluation (RSE) activities at the
Rosemary Complex site (the site) in Roanoke Rapids, Halifax County, North Carolina. This report
includes five enclosures and four attachments. Figures are in Enclosure 1. Data summary tables are in
Enclosure 2. Logbook notes are in Enclosure 3. The photographic log is in Enclosure 4. The Tetra Tech
data validation report is Enclosure 5. Attachments 1 through 4 are the Tetra Tech -subcontracted
laboratory data packages.
BACKGROUND
The Rosemary Complex RSE site (the site) is located at 1200 Henry Street, Roanoke Rapids, North
Carolina and consists of nine contiguous parcels (54.13 acres) located between West loth Street to the
north, Roanoke Avenue to the east, and West 13th Street to the southwest (see Figure 1 in Enclosure 1).
Mid -Atlantic Associates, Inc. completed a Phase I Environmental Site Assessment (ESA) report on the
site dated September 30, 2014. The ESA 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 (West Point Stevens [WPS]) as the
Rosemary Complex. The site once contained approximately 15 buildings at the height of its development
(circa 1994). Nine of the original buildings remain and include the northern portion of Rosemary Mill
No. 1; a former company store building and storage outbuilding; a metal -sided "Slasher" building; and
an assemblage of five adjoining buildings that include the southern portion of Rosemary Mill No. 3, the
Delta 4 Finishing Plant, Roanoke Fabrication Annex, Roanoke Fabrication Plant, and the Roanoke
Distribution warehouse.
The site was an integrated textile facility that produced both finished (dyed) and greige goods
(unfinished) from cotton and polyester raw materials. In 1996, when WPS purchased the site from the
Bibb Company, the facility manufactured terry products and napery (cloth napkins). Between 1996 and
2003 (when manufacturing ceased), the facility produced terry products, such as towels and wash cloths.
Manufacturing operations included yarn making, weaving, bleaching, dyeing, and sewing. Sonrise
purchased the site in May 2005 and has dismantled some of the buildings for their salvage value.

The ESA report prepared by Mid -Atlantic identified the following Recognized Environmental
Conditions (RECs):
• Several potential contaminant sources are related to the site's long-term operation as a
textile mill, including use of cleaning solvents, degreasers, petroleum products, bleaches,
dyes, and acids. These contaminants may be located in soil, groundwater, and underground
utilities and vaults potentially remaining below the facility.
• The documented presence of total petroleum hydrocarbon soil contamination related to use
of a 550-gallon diesel fuel underground storage tank (UST) and possibly two other gasoline
or varsol USTs removed at an earlier date, for which a closure report was apparently
submitted to the North Carolina UST Section but was not provided to Mid -Atlantic for
review
• The potential for groundwater contamination associated with the documented release from a
former diesel fuel UST
• The potential for groundwater contamination associated with the historical use of two
adjacent properties used for vehicle repair
Mid -Atlantic conducted a Limited Environmental Site Assessment (LSA) in 2016 to determine if the
RECs identified in the ESA had adversely impacted the site. The objective of the LSA was to determine
if contaminants of concern were present at levels that could be an impediment to future redevelopment.
The LSA identified semivolatile organic compounds in soil in the central portion of the site above the
Protection of Groundwater (POG) Preliminary Soil Remediation Goals (PSRGs). Benzo(a)pyrene, a
polycyclic aromatic hydrocarbon that is a byproduct of industrial processes, was also detected above
residential health -based PSRGs. Two polychlorinated biphenyl mixtures, Aroclor 1254 and Aroclor
1260, were detected near the location of an on -site transformer at concentrations above the POG PSRG.
Contaminants in soil were not detected in excess of their industrial health -based PSRGs.
Chlorinated solvent constituents were exhibited in groundwater across the site. Tetrachloroethylene
(PCE) was the most prevalent. Other chlorinated solvents detected include 1, 1 -dichloroethane (DCA),
1, 1 -dichloroethylene (DCE), 1,2-DCA, 1, 1, 1 -trichloroethane, and trichloroethylene (TCE).
Halifax County Business Horizons, Inc. petitioned for entry of the site into the North Carolina
Brownfields Program (NCBP) in January 2016 and received their Letter of Eligibility in February 2016
(letter dated February 29, 2016). On October 2, 2017, the NCBP issued a Request for Additional
Assessment outlining additional activities required by their program. The assessment activities, detailed
in the February 8, 2021 Mid -Atlantic site -specific QAPP, were discussed and agreed upon during a
December 3, 2020 site visit with the NCBP project manager. The principal objective of this investigation
was to evaluate the potential for identified on -site contaminant source areas to grossly impact the site
and determine whether such conditions could impact the site's redevelopment.
In 2021, Mid -Atlantic conducted another LSA. Volatile organic compounds (VOCs) detected in
monitoring well MW-15 (see Figure 3 in Enclosure 1), located in the southern portion on the site,
exceeded several comparison levels. PCE was detected at 7,380 micrograms per liter (µg/L), which
exceeds the North Carolina Groundwater Quality Standard of 0.7 µg/L, the residential groundwater
vapor intrusion screening level of 12 µg/L, and the non-residential vapor intrusion screening level of 48
µg/L. TCE was detected in MW-15 at 2,910 µg/L, which exceeds the North Carolina Groundwater
Quality Standard of 3.0 µg/L, the residential groundwater vapor intrusion screening level (VISL) of 1.0

µg/L, and the non-residential vapor intrusion screening level of 4.4 µg/L. TCE was also detected in MW-
13 at 5.2 µg/L, which exceeds groundwater and vapor intrusion screening levels. Groundwater flow
across the site was observed to be generally southward. Given the direction of groundwater flow and the
location of monitoring well MW-15 in the southern portion of the site, the potential existed for off -site
vapor intrusion exposure.
Based on this risk potential, the North Carolina Department of Environmental Quality (NCDEQ)
requested that EPA Region 4 conduct an RSE to evaluate the vapor intrusion concern.
REMOVAL SITE EVALUATION ACTIVITIES
EPA requested a multimedia evaluation to assess the potential for downgradient (southward) impacts
from the contamination identified in MW-15. A multi -phase approach was proposed in the Final Quality
Assurance Project Plan: Rosemary Complex submitted by Tetra Tech to EPA on July 27, 2022.
First Mobilization
On August 19, 2022, passive soil gas samplers (PSGs) were installed along West 13th Street during the
first phase of the assessment to determine where the highest levels of groundwater contamination were
exiting the site. PSGs were also installed along the northeastern property boundary (north of the
Dominion Rosemary Power Station), along the southwestern exterior of the main plant building (east of
MW-8), and at the culvert where the unnamed tributary of Chockoyotte Creek flows under Hinson Street
(see Figure 2 in Enclosure 1).
Prior to intrusive work, Tetra Tech completed a North Carolina One Call (NC811) locate request to mark
utilities in the study areas. Tetra Tech also procured Taylor, Wiseman, & Taylor, a geophysical firm, to
screen proposed boring locations with ground penetrating radar and electromagnetic methods to ensure
that no underground utilities would be encountered.
Installation of PSGs was accomplished by drilling a 1.25-inch hole to depth of 12 inches below ground
surface (bgs). An extending hole (with a diameter of 0.5 inch) then was drilled to a depth of 3 feet bgs.
The PSG capsule was then suspended within the hole approximately 9 inches bgs; balled -up aluminum
foil and native soil were then used to seal the top of the hole. In two instances, the PSGs were installed
through pavement; in these cases, the holes were sealed with neat cement. Tetra Tech installed a total of
32 PSGs: 18 along West 13th Street, eight along the northeastern site boundary, three along the
southeastern portion of the main plant building, and three at the Hinson Street culvert. Tetra Tech
requested that PSG analysis and reporting be limited to benzene, toluene, ethylbenzene, and xylene
(BTEX), and PCE and PCE daughter products.
Second Mobilization
EPA and Tetra Tech returned to the site on August 28, 2022 to recover the PSGs and sample three
existing monitoring wells: MW-3, MW-14, and MW-16. All wells were sampled in accordance with the
EPA Region 4 Science and Ecosystems Support Division Field Branch Quality Systems and Technical
Procedures (FBQSTP) Groundwater Sampling, dated April 26, 2017. Wells MW-14 and MW-16 were
sampled with a peristaltic pump; the water level in MW-3 was too low for a peristaltic pump so the field
team purged the well and sampled with a hand bailer. All groundwater samples were analyzed for
volatile organic compounds (VOCs) by EPA Method 8260D. These three wells are depicted in Figure 3
in Enclosure 1.
Third Mobilization
After receiving the results of the PSG sampling, EPA and Tetra Tech returned to the site on September
8, 2022 to install and sample a temporary monitoring well at the location along West 13th Street with the
TOLIN97-030

highest PCE levels. Tetra Tech subcontracted South Atlantic Environmental Drilling and Construction
Co. Inc. (SAEDACCO), a licensed North Carolina driller, to drill and installed temporary monitoring
well TW-01 (see Figure 3 in Enclosure 1) at the location of passive soil gas sample RMC-PSG-12 (see
Figure 2 in Enclosure 1). Following the guidance found in FBQSTP Design and Installation of
Monitoring Wells, dated January 16, 2018, SAEDACCO installed a 1-inch polyvinyl -chloride temporary
well to a total depth of 30 feet bgs. Tetra Tech immediately sampled the well with a peristaltic pump,
and the well was abandoned. The groundwater sample (RMC-GW-TWO1) was analyzed for VOCs by
EPA Method 8260D.
Additionally, Tetra Tech sampled monitoring well MW-15 (Figure 3 in Enclosure 1) with a peristaltic
pump and submitted the sample (RMC-GW-MW 15 [-DUP]) for VOC analysis by EPA Method 8260D.
Tetra Tech also collected surface water samples from two locations: the unnamed tributary of
Chockoyotte Creek at Hinson Street (RMC-SW-01 [-DUP]), and the ditch along the north side at Hinson
Street at the intersection of South Monroe Street. Surface water samples were collected in accordance
with FBQSTP Surface Water Sampling, dated December 23, 2021, and were submitted for VOC analysis
by EPA Method 8260D. These two surface water sample locations are depicted in Figure 4 in Enclosure
1.
SAMPLE RESULTS
None of the soil gas levels detected during the PSG assessment exceeded the EPA Residential Vapor
Intrusion Screening Levels (VISL). A full summary of the results is provided in Table 1 of Enclosure 2.
Full laboratory reports from Beacon Environmental are provided in Attachments 1 and 2.
Groundwater samples confirmed the results of earlier investigations: that contamination is present at
levels exceeding residential VISLs in MW-15. However, the subsequent PSG sampling and temporary
monitoring well sampling results indicated that the resultant soil gas plume is not creating near -surface
concentrations along the site perimeter that exceed residential VISLs.
TCE was also detected in MW-3 at 0.84 J µg/L, which exceeds the residential VISL of 0.52 µg/L;
however, perimeter PSG sampling demonstrated that soil gas contamination downgradient of this well
does not exceed the soil gas VISLs. No other contaminants were detected in any of the other
groundwater samples at levels that exceeded their respective VISLs.
TCE, PCE, and cis-1,2-dichloroethene were detected in the surface water sample at the Hinson Street
culvert; however, none of these detections exceeded a NCDEQ surface water "Class C" freshwater
standards. Full laboratory reports for groundwater and surface water samples are provided in
Attachments 3 and 4.

Criteria
Initial and Continuing Calibrations: Laboratory qualifications indicated that the initial calibration, secondary source verification,
N
and continuing calibrations exceeded acceptance criteria for bromomethane. Because the associated sample results for
bromomethane were nondetect, the results were qualified as estimated (flagged UJ) for the initial calibration and secondary
source verification exceedance.
Overall Qualifications:
See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:
J
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ
The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.
R
The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Other [Calibration and calibration verifications]:
Within
Exceedance/Notes
Criteria
Continuing Calibrations: The laboratory indicated that the continuing calibration verifications exceeded acceptance criteria for
N
bromomethane and vinyl chloride. No qualifications were applied because the associated sample results for bromomethane and
vinyl chloride were non -detect.
Other [Cross -contamination]:
Within
Exceedance/Notes
Criteria
The laboratory noted that sample RMC-GW-TW01 was analyzed immediately after another [unspecified] sample with a high
N
tetra chloroethene concentration; therefore, the tetrachloroethene reported in the sample RMC-GW-TW01 may be a carry-over.
The result was already qualified as estimated due to its low concentration. No further qualification was necessary.

Overall Qualifications:
See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:
J
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J _
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ
The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.
R
The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

BEACON 2203A Commerce Road, Suite 1
Forest Hill, MD 21050 USA
CERTIFICATE OF ANALYSIS 1.410.838.8780
Tetra Tech Site Name: Rosemary Complex Beacon Proposal: 22061OR01A
1955 Evergreen Boulevard Site Location: Roanoke Rapids, NC Lab Work Order: 0006483
Duluth, GA 30096 Project Manager: Jessica A. Vickers Reported: 08/11/2022
Case Narrative
U.S. EPA Method 8260C
All samples were analyzed using thermal desorption -gas chromatography/mass spectrometry (TD-GC/MS)
instrumentation following U.S. EPA Method 8260C, with laboratory results provided in nanograms (ng) and
micrograms per cubic meter (µg/m3). Laboratory QA/QC procedures included internal standards, surrogates, and
blanks based on EPA Method 8260C. Analyses and reporting were under BEACON's Quality Assurance Project Plan.
Passive Soil -Gas Survey Notes
If sample locations are covered with or near the edge of an impervious surface (e.g., asphalt or concrete), the
concentrations of compounds in soil gas are higher than if the surfacing was not present. Therefore, the sample
location conditions should be considered when comparing results between locations.
Survey findings are exclusive to this project and when the spatial relationships are compared with results of other
BEACON Surveys it is necessary to incorporate information from both investigations (e.g., depth to sources, soil types,
porosity, soil moisture, presence of impervious surfacing, sample collection times).
Reporting Limits
The RLs represent a baseline above which results meet laboratory -determined limits of precision and accuracy. All
reported results are within the calibration range. The project method quantitation limit (MQL) is the limit of
quantitation (LOQ) as noted in the data tables. Beacon determined uptake rates for a suite of compounds with the
Beacon sampler for sampling in air. Beacon calculated the uptake rates for the remaining compounds using Graham's
Law of Diffusion. The reported data includes LOQ limits.
Project Details
Samples were received in proper condition and laboratory control parameters were met unless otherwise noted
below. The work performed was in accordance with ISO/IEC 17025:2017, except samples were analyzed within a
24-hour tune window.

QUALIFIERS
Project: ROSEMARY COMPLEX
Pace Project No.: 92624935
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
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 EPA
Method 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.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
CO Result confirmed by second analysis.
C8 Result may be biased high due to carryover from previously analyzed sample.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
