Dear Ms. Eckard:
Progress Environmental Group, Inc. (Progress) is pleased to submit this Report of Closure of
Reservoir for the Erwin Mill Site located at 200 North 13th Street in Erwin, Harnett County, North
Carolina. The assessment describes tasks associated with closure of the Erwin Mill Site Reservoir,
utilizing material previously identified for import. The work was completed in accordance with
the Work Plan previously approved by North Carolina Department of Environmental Quality
(NCDEQ)-Waste Management-Brownfields Redevelopment Section (NCBRS). The Work Plan -
Erwin Mill Site (dated May 8, 2023) and the Environmental Management Plan (dated August 30,
2023) were approved by the NCBRS on September 5, 2023, via electronic email by Ms. Sharon
Eckard prior to the commencement of closure activities.
BACKGROUND
Progress has previously been engaged to assist in the completion of multiple environmentally -
related tasks associated with the Former Erwin Mill site by 200 N 13, LLC. Specifically, Progress
corresponded with the NCBRS regarding the completion of the requirements of the Brownfields
Agreement and assisted in the property transaction as it related to the outstanding environmental
issues at the site. Progress was contracted to assist in proper closure of the reservoir. Through
conversations with the NCBRS, it was required that the open water reservoir be properly closed
in accordance with the Guidelines for the Closure of Permitted Wastewater Ponds and Lagoons,
dated June 22, 2012 for the reuse of the reservoir area. Hart and Hickman, consultant for the
sellers, prepared and submitted to the NCBRS an Asbestos Removal Work Plan dated November
28, 2022 to address the additional work required at the site to satisfy the Brownfields
Agreement. The Work Plan was previously reviewed and approved by the NCBRS.
As a requirement of the Brownfields Agreement, identified asbestos containing material (ACM)
within the reservoir was removed by an asbestos abatement contractor prior to closure activities
of the reservoir. The field activities and subsequent sampling results are summarized in the HRP

Report for Asbestos Abatement and Consulting Services at the Former Erwin MV15 Facility, Erwin,
North Carolina dated June 19, 2023. A copy of this report is attached in the Appendix.
Subsequently, during additional activities on -site, several pipes were located in an overgrown
area of the reservoir with what appeared to be ACM wrapping. In an effort to remove all feasible
ACMs from the reservoir, Progress and its contractor mobilized to the site and removed the piping
and suspected ACMS wrapping.
Progress previously collected soil samples from an undisturbed area within the Heidelberg
Materials Quarry in Erwin, North Carolina as a potential source for import material for the Erwin
Mill Reservoir Backfill project. However, due to timing of the project and the migration of the
mining activities into this area, the area assessed was not used a source of import material.
As requested by the NCDEQ - Division of Water Quality, a water sample for Per- and
polyfluoroalkyl substances (PFAS/PFOS) was collected by Progress personnel on August 1, 2023.
The water sample was collected from the standing water column within Manhole 64, located
northwest of the reservoir, and the suspected source of water entering the reservoir.
The findings of the additional abatement activities, soil sampling of material within the existing
fill of the reservoir, and the testing of the water entering the reservoir are included in Progress
Report Limited Assessment of Reservoir Soil, Material for Import, and PFAS Testing of Water,
dated August 31, 2023. A copy of this report is included in the Appendix.
Because the quarry activities have moved into the area previously assessed for import for the
Brownfields Property, Heidelberg Materials informed Progress that the source of import material
will need to be from an area adjacent to the original area assessed. Following discussions with
NCBRS, it was determined that collecting and testing soil samples from the new area would be
required prior to importing material from the quarry onto the Brownfields Property. Progress was
subsequently contracted to collect and test soil samples from the alternate prospective source of
import material from the quarry.
Progress coordinated access to the Heidelberg Materials site located proximal to the Site in Erwin,
North Carolina. The alternative proposed area of material to be imported to the Site is depicted
on Figure 2. Because the material will be imported onto a North Carolina Brownfields site, the
material must be analyzed prior to being imported onto the Site. Progress elected to collect soil
samples from the quarry in -situ. According to Heidelberg Materials personnel, the potential area
to be quarried for import is located in an area that was formerly agricultural and has not been
previously developed.
Progress utilized a decontaminated hand auger to advance three soil borings within the proposed
area. The hand auger was properly decontaminated using Alconox® and fresh water prior to
use and in between soil borings. Personal protective equipment was replaced in between soil
borings.
The soil borings were advanced to an approximate depth of four feet bls. Soil samples were
collected from the terminus of each soil boring for laboratory analysis. The soil samples were

collected for analysis for volatile organic compounds (VOCs) using EPA Method 8260, semi -volatile
organic compounds (SVOCs) using EPA Method 8270, Total Resource Conservation Recovery Act
(RCRA) Metals using EPA Method 6020, and for hexavalent chromium using EPA Method 7199.
The laboratory was instructed to report the results to the method detection limits.
For QA/QC purposes, one duplicate soil sample (SS-11) was collected and tested using the same
methodologies. The soil samples were placed into laboratory prepared containers and then into
a cooler packed with ice, with a temperature blank, and delivered under chain -of -custody to a
North Carolina certified laboratory.
LABORATORY ANALYICAL RESULTS
The results of the soil sampling from the quarry indicated the presence of arsenic, barium,
chromium, lead, and mercury in at least one of the soil samples collected for laboratory analysis.
The concentrations of barium, lead, and mercury did not exceed the Groundwater Preliminary
Soil Remediation Goals (PSRGs), Residential Health Based PSRGs, or the Industrial/Commercial
Health Based PSRGs. Soil samples SS-2 and SS-3 exhibited concentrations of arsenic exceeding
its Residential Health Based PSRG. Each soil sample exhibited a concentration of chromium
exceeding its Protection of Groundwater PSRG and its Residential Risk Based PSRG, with the
concentration in soil sample SS-2 exceeding the Industrial/Commercial Health Based PSRG. The
chromium concentrations detected in the soil sample were well below the Protection of
Groundwater PSRG, Residential Health Based PSRG, and the Industrial/Commercial Health Based
PSRG for chromium (III). Soil sample SS-2 exhibited a concentration of hexavalent chromium
exceeding the method detection limits but below the reporting limits, therefore the concentrations
are estimated. The estimated concentrations of hexavalent chromium in soil sample SS-2
exceeded its Residential Health Based PSRGs, but was below its Protection of Groundwater PSRG
and its Industrial/Commercial Health Based PSRG. Please note, the concentrations of arsenic,
chromium, and hexavalent chromium were similar and within the same order of magnitude
relative to each other and were similar to the concentrations detected in the adjacent proposed
borrow area. Based on the low-level concentrations of arsenic, chromium, and hexavalent
chromium detected in each of the soil samples at similar concentrations, it is Progress' opinion
that the concentrations of arsenic, chromium, and hexavalent chromium reflect naturally
occurring concentrations and are not representative of evidence of a release. SVOCs were not
detected at concentrations exceeding the laboratory's method detection limits. VOCs were not
detected in soil samples with the exception of acetone and total xylenes. Acetone (SS-1 and SS-
2) and total xylenes (each soil sample) were not detected at concentrations exceeding the
applicable standards. Please note, the presence of acetone is a known laboratory contaminant.
Progress did not consider the presence of acetone or total xylenes to reflect conditions at the
quarry and they should not preclude using the material as fill material at the Brownfields property.
The complete summary of the field activities associated with the sampling of the alternate import
site was submitted to the NCBRS as Limited Assessment of Material for -7mportdated October 13,
2023. A copy of this report is included in the Appendix. Approval of the material from the
Heidelberg Materials Quarry to be imported onto the Brownfields Property was received from the
NCBRS on October 18, 2023 via electronic mail. According to electronic mail correspondence
from Ms. Eckard of the NCBRS dated June 16, 2023:

Brownfields Project No. 22058-18-043
Progress Project No. TWO700N. GW
We have evaluated the contaminants and the environmental risk posed by them in the
existing backfill material sampled in May 2023 and the results from the proposed backfill
soil source, Heidelberg Materials, including use of the January 2023 DEQ Risk Calculator
to evaluate the environmental risk posed by each material. Based on a comparison of
contaminants, their concentrations, and the resulting risk calculator input, DEQ accepts
Heidelberg Materials as an approved backfill source for use in the reservoir only.
The risk calculator output for the existing reservoir backfill based on the May 2023 sample
event indicates that acceptable risk thresholds are not exceeded for non-residential worker
exposure scenarios, but are for direct residential (CR=3E-04/H1=1.9), construction worker
(H1=3), and recreator/trespasser (CR=1.6E-04) exposure pathways However, given our
understanding of the preliminary plans to encapsulate these materials, which will thereby
break the exposure pathway once constructed, Brownfields does not object to the use of
the existing material in the reservoir as backfill as long as known ACM, and rebar materials
(as we understand were indicated should be removed by the Solid Waste Section) are
removed.
A copy of the populated 2023 DEQ Risk Calculator was not provided to Progress.
EVACUATION OF WATER WITHIN RESERVOIR
It was the intention of the current property owner to evacuate the remaining water within the
reservoir on the Site in preparation of proper closure. Progress understands that during the
previous decommissioning activities following the plant closure, the reservoir was emptied of its
contents and cleaned. Subsequently, soil and small amounts of building materials were deposited
in the reservoir in an effort to close the former wastewater structure. The reservoir was
approximately 66% filled -in with soil and other construction debris. The balance of the reservoir
was open water. Due to access issues, the depth of the water or thickness of material on the
bottom of the reservoir was not determined.
The reservoir had an estimated volume of 5,000,000 gallons, was approximately 230 feet in
diameter and had a reported depth of 20 feet. The reservoir had concrete sidewalls that extended
aboveground. The sloping sidewalls of the interior of the reservoir and base appeared to be a
thin layer of cemented sand rock, which was easily broken.
Beginning on March 20, 2023 Progress and Stewarts Environmental Services were on -site to
dewater reservoir. Water quality sampling conducted by Progress and others had not indicated
elevated concentrations of targeted compounds within the reservoir. Progress provided a copy
of the most recent round of sampling to the Harnett Regional Water for their review. Progress
requested and received permission from the Harnett Regional Water to pump and discharge the
remaining water within the reservoir. Permission was granted following the submission of a Draft
Pumping Plan dated February 23, 2023 to local and state stakeholders. A copy of that report is
provided in Appendix. Progress received permission from Mr. Kenny Fail of the Harnett Regional
Water on March 7, 2023 via electronic mail to pump the contents of the reservoir to the municipal
sewer system. A copy of the email chain is provided in the Appendix. Progress coordinated with

Harnett Regional Water personnel to determine which manhole located at the site would be most
conducive to pump into to ensure that the sanitary sewer system had the capacity to manage the
dewatering. It was determined that a manhole located on the west side of site at 161" Street and
H Street. The manhole was equipped with a 20-inch concrete drain that was determined to be a
direct conduit to the wastewater treatment plant.
In order to efficiently remove the remaining water from the reservoir, Progress and Stewarts
Environmental Services were contracted to complete the pumping of the reservoir. Progress
provided technical oversight of the project. Stewarts Environmental Services employed the
following equipment and procedures:
• A diesel powered four -inch pump, with rigid four inch suction pipe and four -inch rigid
suction pipe and four -inch lay flat discharge pipe. The pumping rates during the
dewatering ranged from approximately 200 gallons per minute (gpm) to 470 gpm. Please
note, it was not the intention of Progress and its contractors to overwhelm the filtration
media and the sanitary sewer system with the effluent, therefore, the discharge rates
were lower than upward limits of the equipment to minimize discharging sediment and
sludge into the sanitary sewer system;
• A self -leveling float dock strainer was installed to the inlet side of the suction pipe, which
allowed the suction hose to draw water from the only the surface of the pond,
minimizing the disturbance of sediments on the banks and base of the reservoir;
• Progress instructed the contractor to equip the terminus end of the discharge pipe with a
bag filter as a primary preventative measure. The sediment bag was attached to the
discharge hose using fasteners. The contractor constructed a lined receiving pool at the
manhole that contained the terminus of the discharge pipe and filtration bag;
• The contractor installed a Storm Sentinel on the selected sanitary sewer manhole. The
Storm Sentinel is a framed model that comes with an adjustable steel wire frame that fits
within the frame of the manhole creating a low -profile connection to the sewer system.
The Storm Sentinel was equipped with a geotextile fabric that acted as a secondary filter
on the discharge; and,
• Progress instructed the contractor to utilize a two-step process in minimize the pumping
of sediments in the sanitary sewer system. As the depth in the reservoir was near one -
and one-half feet, Progress instructed the contractor to switch to a smaller (two-inch trash
pump) to minimize disturbance of sediments. The contractor pumped the remaining water
to a lined dumpster (20 cubic yard capacity) using the trash pump, and the four -inch
diesel pump was used to pump water from the lined dumpster to the sanitary sewer
manhole.
Progress and Stewarts Environmental Services evacuated approximately 689,000 gallons of water
from the reservoir from March 20-24, 2023. The water was pumped from the reservoir to a
manhole located west of Building 11, subsequent to approval from Harnett Regional Water
(approval via March 7, 2023 via electronic email), to discharge to the Harnett Regional Water
Wastewater Treatment Plant. Following the removal of the water it was determined that the base
of the reservoir was not concrete as suspected, but rather a sand rock material that was easily
broken using hand tools. This material was thin, no more than two to three inches thick. Beneath
the sand rock material was an impermeable clay that seems to have been placed on -site during

the construction of the reservoir. The original drain for the reservoir consisted of a metal junction
box that was connected to a metal discharge pipe that could be opened to drain the water. Upon
inspection, the drainpipe was determined to be intentionally mangled in an apparent effort to
prevent future flow. Progress also identified a manhole that appeared to have been related to
the discharge pipe to the west of the reservoir along the flank of the reservoir. According to
multiple sources, the pipe that was formerly used to drain the water to the clarifier was grouted
closed. Inspection of the pipe confirmed that the drain pipe was not functional.
Once the water in the reservoir was drawn down, it was noted that water was flowing into the
reservoir through a pipe located in the northeastern quadrant of the reservoir. It was noted that
water was observed flowing through Manhole 64, as marked on the attached map, to the pipe
protruding into the reservoir. Inspection downhole within Manhole 64 indicated one pipe
extending northeast towards Buildings 9 and 10. The pipe appeared to have been grouted
previously, with only a small portion of the pipe diameter allowing water to flow. The water
appeared to be under pressure indicating a larger volume of water within the pipe. It is likely
that the water in the reservoir was acting as a hydraulic dam to the water in the pipe, resulting
in flow of the water into another stormwater pipe. On March 20, 2023, prior to the
commencement of dewatering activities, Progress and Harnett County personnel noted sounds of
water flowing in a manhole located northwest of the reservoir and a drop inlet just west of the
reservoir. The source of the water in the pipe discharging to the reservoir had not been
determined but was likely stormwater flowing from the roof drain on the site buildings.
The site activities were inspected by Ms. Amanda Thompson of NCDEQ-Solid Waste Section on
March 23, 2023 during the pumping of the water in the reservoir. Based on Ms. Thompson's
observation, the material that was visible in the cross-section of the fill material appeared to meet
the definition of beneficial fill and was determined to be left in -place. Ms. Thompson requested
that Progress and its contractors use mechanical means to remove and properly dispose of the
numerous strands of rebar extruding from the pieces of concrete throughout the exposed fill
material prior to adding additional fill material. Discussions with Mr. Jason Watkins indicated that
this summary report should address key elements of the planned closure of the reservoir and be
in compliance with Solid Waste rules for the closure of waste lagoons.
Progress received permission to pump the residual fluids from the reservoir from Harnett Regional
Water on September 11, 2023 from Vicky Paseur via electronic mail. On September 21, 2023,
Tim Dudley Services, contractors for the owner, began pumping the fluids that accumulated in
the reservoir since the initial evacuation in March 2023. The methodology employed was
consistent with the previous site activities. Progress received approval from the Harnett Regional
Water to pump the water from the reservoir into the manhole located to the west of Building 11.
Progress received permission from Ms. Vicy Payseur of the Harnett Regional Water on September
11, 2023 to pump the contents of the reservoir using similar methodology as during previous
pumping activities. A copy of the email chain is provided in the Appendix. During the pumping
of the reservoir approximately 607,056 gallons of water from the reservoir was directed into the
sanitary sewer system. Pumping of the reservoir was completed on October 17, 2023. The
pumping of the reservoir was intermittent and included delays to prohibit additional flow into the
reservoir. A pipe that was located within Manhole 64 was previously plugged with concrete. A
small area on the perimeter of this plug was allowing water to flow through the manhole and into

the reservoir. This leak was plugged with hydraulic cement and the flow of water was stopped
on October 2, 2023. Additionally, the pipe connected to Manhole 64 that extends into the
reservoir was capped with a fitted compression cap to prevent any water that enters the pipe in
the future to flow into the reservoir.
IMPORT OF MATERIAL
After the completion of evacuation of water within the reservoir and approval of Progress' Limited
Assessment of Reservoir Soil, Material for Import, and PFAS Testing of Water dated August 31,
2023, Progress and contractors for the owner began importing fill material from the Heidelberg
Materials Quarry in Erwin to the Erwin Mill Site to facilitate the closure of the reservoir on October
19, 2023. Material from on -site demolition that met the criteria to be considered beneficial fill
was placed in the bottom of the reservoir. This material consisted of unpainted bricks, concrete
block, and concrete slabs. Progress was diligent in not allowing the contractor to place wood or
metal into the reservoir. Evidence of contamination (i.e paint or other coating/covering
substances) were not noted on the concrete that was deposited in the reservoir. Metal rebar
identified protruding from previously deposited concrete slabs within the reservoir were manually
cut flush with the nearest edge of the concrete as requested by NCDEQ-Solid Waste Section
personnel. The metal was segregated on -site and transported off -site for proper recycling. The
metal was recycled at Dunn Scrap Iron located in Dunn, North Carolina. A copy of the disposal
ticket is included in the Appendix.
Progress and the contractors for the owner utilized drivers from several local trucking companies
to assist in facilitating the material transfer over several days. Fill material that was imported to
the reservoir location was subsequently distributed and compacted utilizing heavy equipment,
including bulldozers, skidsteers and roller compactors. On a daily basis, heavy equipment
operators worked to distribute imported fill material evenly throughout the reservoir and ensure
sufficient compaction. High clay content in the imported fill material assisted subcontractors in
maximizing compacted soil density. Continuous compaction activities, completed throughout the
import activities, included pulling a roller compactor behind a tractor and the use of a vibratory
sheepsfoot. Please note, compaction testing was not completed during the import activities.
The concrete sidewalls were demolished to ground level using a skidsteer equipped with a jack
hammer. Concrete material from the sidewalls were utilized in backfilling the reservoir, any rebar
within the sidewalls was removed and not included in the material used as fill.
The transfer and import of fill material to the reservoir site began on October 19, 2023 and was
completed on November 9, 2023. Over the span of this time period, Progress estimates that
approximately 1,238 truckloads of fill material were imported from the Heidelberg Materials
Quarry to the Erwin Mill Site. Please note, the material was loaded by the contractor outside of
the active area of the mine. Diligence was taken in counting the truckloads from the quarry;
however, the truckloads were not weighed departing the quarry, and therefore, individual
manifests were not generated. Assuming an average capacity of 10 cubic yards of material within
each truckload, this equates to approximately 12,380 cubic yards of imported fill material (or
15,475 tons, assuming an average material density of 2,500 Ibs per cubic yard). Progress asserts
that all material imported to the historic reservoir site and utilized in closure meets the definition
of beneficial fill. The backfill material was placed to a level consistent the surrounding ground

surface, completely filling the reservoir. A copy of a memo from Mr. Mike Hair of Heidelberg
Materials is included in the Appendix of this report.
Progress personnel were on -site through the entirety of the backfilling activities to document the
number of trucks depositing material within the reservoir, to confirm the material from the import
area did not differentiate substantially from the material previously analyzed, and to document
only material meeting the criteria of beneficial fill were deposited in the reservoir. Progress
employed a photoionization detector to ensure organic vapors were not adversely impacting the
workspace. Photographs of the backfilling activities are included in the Appendix of this report.
During the next phase (estimated to be within three to six months), contractors will begin
importing gravel from the Heidelberg Materials Quarry. The gravel will be used as temporary
surfacing material allowing the imported material to settle and any areas of unpreferred
settlement will be remedied with additional gravel material. Once it is determined that the fill
material is stable, the area will be overlain by pavement. It is likely that the area will not be
paved in approximately one year. Prior to the placement of pavement in the area of the former
reservoir, discussions with a geotechnical engineer will occur to determine whether testing and/or
special provisions should be made prior to finishing the parking/loading dock area.
CONCLUSIONS
Subsequent to receiving permission from the Harnett Regional Water, 607,056 gallons of water
from the reservoir was directed into the sanitary sewer system from September 21, 2023 to
October 17, 2023. The pumping of the reservoir was intermittent and included delays to eliminate
additional flow into the reservoir. A pipe that was located within Manhole 64 was plugged with
concrete, stopping flow into the manhole. Additionally, the pipe connected to Manhole 64 that
extends into the reservoir was capped with a compression cap to prevent any water that enters
the pipe in the future to flow into the reservoir.
The results of the soil testing within the alternate quarry location at the Heidelberg Materials
Quarry did not indicate the presence of VOCs (with the exception of acetone and total xylenes)
or SVOCs. The metals detected in the soil samples collected from the quarry are considered in
the range of naturally occurring metals and are consistent or detected at concentrations less than
the concentrations detected in the soil samples collected from within the reservoir. Progress
received approval from the NCBRS to use the alternate quarry location as a source of material for
the backfilling activities.
Progress supervised the import of approximately 12,380 cubic yards of material from the
Heidelberg Materials Quarry from October 19, 2023 to November 9, 2023. The material was
placed, spread, and compacted using machinery applicable for these types of activities. The
material was compacted to the satisfaction of on -site personnel but compaction testing was not
completed as the reservoir area will be used as a parking lot and loading dock area in the future.
The area will not be paved until it is given adequate time to settle. Any settlement will be
remedied with additional gravel as needed.

consulting services performed at the Former Erwin Mills Facility located at 200 N. 13t" Street in
Erwin, North Carolina. The abatement activities were conducted in multiple locations of the facility
including Buildings 7 — 9 and 14 - 18. The abatement work included non -friable methods to assist
in keeping the schedule moving forward and to minimize costs.
SCOPE OF SERVICES
Task 1: Asbestos Abatement Activities
HRP retained the services of T&T Abatement Contractor Services, Inc., a North Carolina Licensed
Asbestos Abatement Contractor, to provide all labor, materials, equipment and disposal for the
proper abatement of the asbestos -containing material (ACM) identified. The ACM included
removal of flooring materials to allow for interior demolition. The ACM was identified in the Former
Erwin Mills Facility Asbestos Survey Report, dated February 7, 2020. Asbestos -containing pipe
insulation was not included in this abatement. The abatement work was performed in accordance
with all applicable Federal, State, and local regulations. The abatement included the following:
Building 7 - The abatement consisted of the removal of asbestos -containing floor tile from two
rooms identified as sample area 13, two layers on 1/2" plywood, approx. 510 sf.
Buildina 8 - The abatement consisted of the removal of asbestos -containing floor tile and
associated mastic on concrete identified as sample area 35, approx. 500 sf.
Building 17 (Basement) - The abatement consisted of the removal of asbestos -containing floor
tile and associated mastic on concrete identified as sample area 17, approx. 1,030 sf.
Building 18 - The abatement consisted of the removal of asbestos -containing flooring on concrete
identified as sample area 24 & 25, approx. 1,370 sf.
Building 16 - The abatement consisted of the removal of asbestos -containing flooring and wood
on concrete identified as sample area 3, 8 & 9, approx. 1,800 sf.
Site work included installation of five separate containments, utilizing 6-mil plastic sheeting,
negative air machines and wet methods. Non -asbestos items and debris, such as carpet,
furniture, trash, etc. in the work areas were moved outside the work area to remain.

Work also included removal of the asbestos contaminated debris piles in the nearby reservoir.
The debris piles were removed and loaded into disposal containers and transported to an
approved landfill for disposal. Waste manifests from the waste disposal are attached.
Task 2: Project Management, Final Inspection and Clearance Testing
HRP provided project management throughout the duration of the asbestos abatement activities.
The HRP representative performed the following activities during the abatement project: daily
safety meetings; reviewed applicable paperwork for each day; daily log and reviewed daily work
activities at each work area.
HRP performed a final inspection of each asbestos abatement work area to confirm the successful
removal of the asbestos containing materials. Any deficiencies noted at the time of the inspection
were directed to the abatement contractor and were remedied immediately. Upon the satisfactory
completion of the inspections, Clearance testing was conducted consisting of the collection of air
samples and analyzed by Phase Contrast Microscopy. The results of the testing were evaluated
to confirm the post remediation airborne fiber concentrations were below the EPA recommended
clearance value of 0.01 fibers/cc. The five areas all passed clearance testing. The contractor
dismantled the containments and final cleaned the areas.
HRP's representative observed the removal of the debris from the reservoir and confirmed it is
visually complete and collected bulk samples below the piles for confirmation testing. Bulk sample
results are attached and all were none detected.
If you have any questions about this proposal, please do not hesitate to contact us at

Dear Toni:
Enclosed please find the report covering our asbestos industrial hygiene services provided at
200 13th street Erwin NC on 18 March 2023.
Please feel free to call me at 336 681-7288 if you have questions about the report or need
additional information. Thanks for the opportunity to be of service.
BACKGROUND
Triad Environmental was contracted by T&T Abatement Contractor Services Inc., to provide a
post abatement visual inspection and PCM clearance relative to an asbestos removal project at
200 131h sreeet Erwin NC. The purpose of the project was to remove asbestos containing
flooring from three work areas ranging in size from 250sf-800sf. T&T Abatement Construction
Services, Inc. conducted abatement work.
Asbestos materials were removed utilizing a full enclosure negative pressure enclosure and wet
method for the flooring removal according to the Occupational Safety and Health Administration
procedures for Class I and II asbestos removal operations [29 CFR 1926.1101 (g), (4) & (5)].
The hygienist inspected the project area prior to the beginning of clearance activities in order to
verify proper engineering controls.
SCOPE OF WORK
Asbestos industrial hygiene services provided for this project included surveillance of job site
conditions for compliance with project specifications and OSHA/EPA regulations. Air monitoring
was conducted following all removal activities. Personnel exposure monitoring was performed
to assess the concentration of asbestos fibers in the breathing zone of abatement workers in the
regulated work area. Such sampling was conducted in accordance with 29 CFR 1926.1101
Appendix A to aid in the preparation of Negative Exposure Assessment for workers.
Following the abatement action, a visual inspection of the work areas was conducted to
determine that all asbestos -containing materials had been removed according to project
specifications and that no visible asbestos debris remained. Visual inspection activities were
conducted in accordance with ASTM Method E1368-90. Final (clearance) air sampling was

conducted following the visual inspection to document the level of airborne asbestos remaining
in the work area.
Project areas were released to the Contractor after completion of a successful final visual
inspection; air -sampling results were below the North Carolina clean air criterion.
A daily log was maintained for activities conducted during the course of work. This report
summarizes the services provided during the project work period, air monitoring, visual
inspections, and final air sampling tests.
PROJECT OBSERVATION / VISUAL INSPECTION
Commencing 18 March 2023 non -friable asbestos containing flooring materials was remove
from three areas located at the Erwin Business Comples Erwin NC, utilizing wet abatement
methods, all accessible flooring was removed. Following the asbestos removal, disposal and
cleanup in the work area, Triad conducted a final visual inspection noting no gross suspect
material in the abated areas.
AIR SAMPLING PCM AIR SAMPLING PROTOCOL AND ANALYSIS
PCM air sampling was conducted to determine the effectiveness of the engineering controls and
work practices in limiting fiber release. Sampling guidelines were followed as set forth in North
Carolina GS 130A-444 through 451 and 15A MCAC 0607. All efforts are made to obtain a
sufficiently high air volume to ensure an appropriate quantization limit. This is not always
achievable in certain environments where high levels of particulate are present that may
overload sampled filters. If present, such conditions are specifically noted in the attached field
data reports. All air samples were submitted under proper chain of custody to EMSL, Inc. of
Kernersville, North Carolina (Laboratory #10-1159) for PCM analysis in accordance with the
NIOSH 7400 Method.
Results of clearance monitoring at the end of the project indicated airborne fiber concentrations
ranging below 0.01f/cc inside the sampled areas. These results indicated compliance with the
North Carolina clearance criterion applied to this project.
SUMMARY
Based on a successful visual inspections and air sample results below the acceptance criterion,
the asbestos abatement area was determined to be ready for re -occupancy on 18 March 2023.
The abatement site was released to the Contractor following verbal communication of final
inspection and air sampling results.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOBs) such as
vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that
all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission
Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is
not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on
request.

using EPA Method 7199. The laboratory was instructed to report the results to the method
detection limits.
For QA/QC purposes, one duplicate soil sample (Quarry-33) was collected and tested using the
same methodologies. The soil samples were placed into laboratory prepared containers and then
into a cooler packed with ice, with a temperature blank, and delivered under chain -of -custody to
a North Carolina certified laboratory.
Stormwater in Manhole 64
As requested by the Division of Water Quality, water samples for Per- and polyfluoroalkyl
substances (PFAS/PFOS) were collected by Progress personnel on August 1, 2023. The water
sample was collected from the standing water column within Manhole 64, located northwest of
the reservoir, and the suspected source of water entering the reservoir. Standing water was
present approximately 8 feet below the manhole, and no flow was observed within the manhole
during the sampling event. A grab sample was collected with a PFAS/PFOS-free high density
polyethylene disposable bailer and clean nylon string, using clean nitrile gloves to avoid contact
between skin and the sample. No cosmetics, lotions, sunscreen, or bug repellent were used on
the day of sample collection by field personnel. The bailer was lowered three feet below the water
surface and retrieved. The bailer did not contact the bottom of the manhole. No water quality
parameters were measured at the time of sampling, but the water exhibited low turbidity with a
slight brown tint. The sample was decanted directly from the bailer to laboratory -supplied
containers for analysis of PFAS/PFOS via EPA Draft Method 1633. Samples were immediately
sealed in clean polyethylene bags and placed in a cooler packed with ice. Samples were
transported via chain -of -custody procedures to Pace Analytical Laboratories in West Columbia,
South Carolina.
LABORATORY ANALYICAL RESULTS
Asbestos Containing Material Removal
Progress personnel supervised the removal of identified ACMs within several debris piles located
along the northern side of the reservoir. Soil samples collected from beneath the debris piles did
not exhibit evidence of residual ACMs beneath the debris piles and immediately outside of the
reservoir.
During the removal of the debris materials, Progress identified piping with suspect ACMs
wrapping. Following the removal of the suspect ACMs, Progress collected a sample of the material
and tested it for the presence of asbestos. The material exhibited a detectable concentration of
amosite. The test method indicated only the presence of amosite and not a percentage or
concentration of amosite.
Progress and T&T remobilized to remove additional material with hand tools beneath the former
piping with ACMs, attempting to minimally disturb the deposited material. T&T collected a grab
sample from the approximate center of the work area of the material and tested it for the

presence of asbestos. The material exhibited a detectable concentration of amosite. The test
method indicated only the presence of amosite and not a percentage or concentration of amosite.
Reservoir
The results of the soil sampling within the reservoir indicated the presence of arsenic, barium,
cadmium, chromium, lead, and mercury in each of the composited soil samples collected for
laboratory analysis. The concentrations of barium, cadmium, lead, and mercury did not exceed
the Groundwater Preliminary Soil Remediation Goals (PSRGs), Residential Health Based PSRGs,
or the Industrial/Commercial Health Based PSRGs. Each soil sample exhibited a concentration of
arsenic exceeding its Residential Health Based PSRG, with the concentration detected in SB-2
exceeding its Industrial/commercial Health Based PSRG. Each soil sample exhibited a
concentration of chromium exceeding its Industrial/Commercial Health Based PSRG. The
chromium concentrations detected in the soil sample are well below the Groundwater PSRG,
Residential Health Based PSRG, and the Industrial/Commercial Health Based PSRG for chromium
(III). Hexavalent chromium was only detected in soil sample SB-22 (duplicate of soil sample
SB-2) at a concentration exceeding its Residential Health Based PSRG, but below its Protection of
Groundwater PSRG and its Industrial/Commercial Health Based PSRG. Several targeted VOC
compounds were detected in the soil samples collected from within the reservoir, with only 1,2,3-
trichlorobenzene being detected at a concentration that exceeds its Protection of Groundwater
PSRG. Several targeted SVOCs were detected in the soil samples collected within the reservoir.
Concentrations of targeted SVOCs were not detected at concentrations exceeding their respective
Protection of Groundwater PSRGs, Residential Health Based PSRGs, and/or Industrial/Commercial
Health Based PSRGs.
Quarry
The results of the soil sampling from the quarry indicated the presence of arsenic, barium,
chromium, lead, and mercury in each of the composited soil samples collected for laboratory
analysis. The concentrations of barium, lead, and mercury did not exceed the Groundwater
PSRGs, Residential Health Based PSRGs, or the Industrial/Commercial Health Based PSRGs. Each
soil sample (with the exception of soil sample Quarry-3) exhibited a concentration of arsenic
exceeding its Residential Health Based PSRG. Each soil sample exhibited a concentration of
chromium exceeding its Protection of Groundwater PSRG and its Residential Risk Based PSRG,
with soil samples Quarry-1, Quarry 3, and Quarry-33 exceeding the Industrial/Commercial Health
Based PSRG. The chromium concentrations detected in the soil sample are well below the
Protection of Groundwater PSRG, Residential Health Based PSRG, and the Industrial/Commercial
Health Based PSRG for chromium (III). Each of the soil samples collected from the quarry
exhibited concentrations of hexavalent chromium exceeding the method detection limits but
below the reporting limits, therefore the concentrations are estimated. The estimated
concentrations of hexavalent chromium in each of the soil samples exceed its Residential Health
Based PSRGs, but are below its Protection of Groundwater PSRG and its Industrial/Commercial
Health Based PSRG. Please note, the concentrations of arsenic, chromium, and hexavalent
chromium were similar and within the same order of magnitude relative to each other. Based on
the low-level concentrations of arsenic, chromium, and hexavalent chromium detected in each of

the soil samples at similar concentrations, it is Progress' opinion that the concentrations of arsenic,
chromium, and hexavalent chromium reflect naturally occurring concentrations and are not
representative of evidence of a release. SVOCs were not detected at concentrations exceeding
the laboratory's method detection limits. VOCs were detected in soil samples with the exception
of chloromethane and methylene chloride. Chloromethane was not detected at concentrations
exceeding the applicable standards. Methylene chloride was detected at concentrations
exceeding its Protection of Groundwater PSRG in soil samples Quarry-3, Quarry-33, and Quarry-
4. Please note, the presence of methylene chloride is a known laboratory contaminant. Progress
does not consider the presence of methylene chloride to reflect conditions at the quarry and
should not preclude using the material as fill material at the Brownfields property.
Stormwater in Manhole 64
Laboratory analysis of the water sample collected from Manhole 64 exhibited 14 PFAS/PFOS
compounds ranging in concentration from 1.2 ng/L to 170 ng/L, with a total combined
concentration of PFOS/FPAS compounds of 259.9 ng/L. North Carolina currently has no standards
associated with PFAS compounds for groundwater or surface water. The source of the PFAS
impacted water within Manhole 64 is unknown.
CONCLUSIONS
Following the removal of the ACMs located along the northern side of the reservoir, soil sampling
within the reservoir and immediately outside of the reservoir did not indicate the presence of
asbestos. Soil samples collected following the removal of the debris did not exhibit evidence of
residual ACMs beneath the debris piles and immediately outside of the reservoir.
Additional ACMs were identified within the reservoir during additional phases of work at the site.
Following the removal of the suspect ACMs, Progress collected a sample of the material and tested
it for the presence of asbestos. The material exhibited a detectable concentration of amosite. In
an effort to remove residual ACMs within the deposited material, T&T returned to the site to
excavate the area using hand tools. T&T collected a grab sample from the approximate center
of the work area of the material and tested it for the presence of asbestos. The material exhibited
a detectable concentration of amosite. Based on the presence of non -visual ACMs within the
material deposited in the reservoir, Progress recommends encapsulating the remaining ACMs with
clean fill material imported from the Hanson Quarry and encapsulating the entire reservoir with
asphalt or concrete as previously proposed. Based on the lack of visual evidence of ACMs in the
deposited material, it is Progress' opinion that additional asbestos abatement activities will lead
to introducing asbestos fibers to the air that may adversely affect abatement contractors and
nearby residents.
Although the soil samples collected from within the reservoir indicated concentrations exceeding
their respective Protection of Groundwater PSRGs, Residential Health Based PSRGs and/or
Industrial/Commercial Health Based PSRGs, a three to four foot layer of clean, imported backfill
will be placed on top of this material, creating a cap such that exposure to the contaminated
material would not be expected. Additionally, the clean imported material will be covered with a

layer of gravel (approximately six to twelve inches), which will then eventually be capped with
asphalt or concrete following adequate time for settlement. It is the intention of the PD to utilize
the reservoir as a parking pad.
The results of the soil testing within the quarry did not indicate the presence of VOCs (with the
exception of chloromethane and methylene chloride) or SVOCs. The metals detected in the soil
samples collected from the quarry are considered in the range of naturally occurring metals and
are consistent or detected at concentrations less than the concentrations detected in the soil
samples collected from within the reservoir.
The imported material from the quarry will be deposited in lifts allowing for sufficient compaction
utilizing compaction equipment. The material that is already located within the reservoir will not
be disturbed or minimally disturbed. Attempts to compact the existing material will be made;
however, due to the unconsolidated nature of the material it is unlikely that industry standard
compaction rates for parking areas will be achieved in this area. The PD understands the nature
of the project and to ensure that the imported material and existing fill material within the
reservoir is allowed to compact to to fullest extent possible, Progress and its subcontractors will
cover the imported material with gravel, imported from the same quarry. The parking lot and
loading dock areas will not be immediately covered in pavement but rather used as a gravel
parking lot to further compact the material with vehicular traffic. Progress will employ a project
professional to supervise the import of material to ensure that the material imported into the
reservoir meets the definition of beneficial fill and that materials previously deposited in the
reservoir that may be disturbed during grading do not require removal and/or additional
assessment. Progress will employ a PID during material disturbance to ensure a safe working
environment. Once a satisfactory level of imported soil is achieved, Progress will instruct the
contractor to import gravel from the Hanson Quarry. According to North Carolina NCBRS
guidelines the imported gravel will not require testing prior to import or placement. Off -site
material will not be imported without written approval from the North Carolina NCBRS.
PFAS impacted water was identified in the water sample collected from Manhole 64 located proximal
to the reservoir and the likely pathway for stormwater that enters the reservoir. Progress has
reviewed stormwater and sanitary sewer maps for the facility; however, it is unclear the pathway
that stormwater and sanitary sewer flows beneath the site and how those flows impact the water
that enters the reservoir. According to on -site personnel and Harnett County officials, once the Plant
was shuttered in 2000, the Harnett County Public Works noted significant increases in flow to the
sanitary sewer following precipitation events. In an effort to control wastewater from the site,
Harnett County personnel blocked manholes at the site that were tied to the sanitary sewer system.
By blocking the manholes the variation in the flows from the site were mitigated. Please note, PFAS
compounds in drinking water, groundwater, and wastewater are ubiquitous in the Cape Fear River
Basin. The source of the PFAS in Manhole 64 cannot be determined. Based on the presence of
the PFAS compounds in the water sample, Progress has elected not to pipe this water through the
dam and discharge it to the surface water body downgradient of the reservoir. Alternatively,
Progress proposes to block both pipes in Manhole 64, extending from the plant and the one
connecting to the reservoir with inflatable plugs. The pipe within the reservoir will be permanently

the inflatable plugs are prohibiting flow from the underground piping network to the reservoir.

QUALIFIERS
Project: HPR NC - Erwin Part 1
Pace Project No.: 92665969
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.
BATCH QUALIFIERS

EMSL maintains liability limited to cost of analysis. Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not
be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations . The report reflects the samples as
received. Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control
criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA
600/104-82-020 "Interim Method") but augmented with procedures outlined in the 1993 ("final') version of the method. This report must not be used by the client to claim product certification,
approval, or endorsement by NVLAP, NIST or any agency of the federal government. Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum,
wallboard, etc.) are reported as a single sample. Some samples may contain asbestos fibers present in dimensions below PLM resolution limits. EMSL suggests that samples reported as <0.25 %
or none detected undergo additional analysis via TEM. Estimation of uncertainty is available on request.
