Dear Ms. Eckard:
Progress Environmental Group, Inc. (Progress) is pleased to submit this Limited Soil Sampling
Assessment for the Erwin Mill Site located at 200 North 13th Street in Erwin, Harnett County,
North Carolina. The assessment describes environmental tasks associated with the sampling of
backfilled soil within the reservoir as well as the analytical testing of the material identified for
import. The work was completed in accordance with the Work Plan approved by North Carolina
Department of Environmental Quality (NCDEQ)-Waste Management-Brownfields Redevelopment
Section (NCBRS).
BACKGROUND
Progress has previously been engaged to assist in the completion and submittal of a North
Carolina Brownfields Eligibility Application, surface water sampling of the reservoir, and a Phase
I Environmental Site Assessment by 200 N 13, LLC. Subsequent to the completion of the Phase
I Environmental Site Assessment, Progress corresponded with the NCBRS regarding the
completion of the requirements of the Brownfields Application and assisting in the property
transaction as it relates to the outstanding environmental issues at the site. Progress has been
contracted to assist in the completion of the only outstanding issue related to the Brownfields
Agreement - the proper closure of the reservoir. Through conversations with the NCBRS, it will
be 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. Hart and
Hickman, consultant for the sellers, prepared and submitted to the NCBRS a Worl(Planto address
the additional work required at the site to satisfy the Brownfields Agreement. The Work Plan has
been reviewed and the comments from Ms. Sharon Eckard are as follows:

We have reviewed the Revised Asbestos Removal Work Plan, Erwin Mill (Hart &
Hickman, December 15, 2022), this work plan is approved.
This work plan fu/d/ls a portion of the requirements for non -PCB assessment and
remediation activities as defined in subparagraph 15.b./, of the Brownfields
Agreement for this Brownfields Property, which was recorded on December 30, 2022
at the Harnett County Register of Deeds (Book 4178/pgs 865-1061). The remainder
of this subparagraph would be fulfilled upon the approval of post-remediation report
to DEQ's written satisfaction.
In addition to satisfying the requirements of subparagraph 15. b, i., the requirements
of subparagraph 15. b. //. with respect to the actions related to the reservoir based on
the plans for its future use remain. We had provided some comments on the /n/t/a/
version of this work plan, which remain unanswered
What /s the plan for capping/reuse /n this area? Parking lot and engineering
assessment planned?
1. Would that entail breaking the side walls or bottom to drain water to allow
drainage prior to capping?
2. Only have data from 0-1 ft /n two discrete locations; if material remains /n the
reservoir would need data representative of the column including t/OCs, Sl/OCs, RCRA
metals, and asbestos.
Attached please find guidance used by the DEQ Division of Water Resources (DWR)
for closure of wastewater ponds that may be helpful in moving along the discuss/on
about the fate of the reservoir.
Progress has been requested to evaluate the costs and options for meeting the closure criteria as
it fits into the redevelopment plan. Based on available information Progress will complete the
following:
o Correspond with NCDEQ — Solid Waste Section about applicable materials that
can be used as beneficial fill within the reservoir;
o Coordinate with Harnett County Public Works concerning sending the residual
fluids from the reservoir to the Publicly Owned Treatment Works (POTW);
o Pump residual fluids from the reservoir, satisfying the requirements of Harnett
County
o Obtain off -site suitable fill (Progress will collect and test samples from the source
of the import material and receive written approval from the NCBRS prior to
import);
o Prepare a Work Plan that stipulates required steps to achieve lagoon closure;
o Implement closure activities;
o Obtain necessary permits from local and state agencies, as necessary;
o Complete an erosion control plan, as required;

o Perform supervisory and sampling activities;
o Complete necessary reporting confirming that the proposed steps were
completed in accordance with the Work Plan.
Following discussions with the PD and the NCDEQ and numerous site visits, Progress provides a
description of the following scope of services.
It is 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 is
approximately 66% filled -in with soil and other construction debris. The balance of the reservoir
is open water. Due to access issues the depth of the water or thickness of material on the bottom
of the reservoir can not be determined.
The reservoir has an estimated volume of 5,000,000 gallons, is approximately 230 feet in
diameter, and has a reported depth of 20 feet. The reservoir reportedly has concrete sidewalls
and base.
Beginning on March 21, 2023, Progress and its contractor were on -site to dewater the reservoir.
Water quality sampling conducted by Progress and others has not indicated elevated
concentrations of targeted compounds within the reservoir. Progress provided a copy of the most
recent round of sampling to the Harnett County Public Works Department for their review.
Progress coordinated with Harnett County Public Works Department 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 north side of the site at 16t" Street and H Street would be the preferred
discharge location. The manhole was equipped with a 20-inch concrete drain that was determined
to be a direct conduit to the wastewater treatment plant.
To efficiently remove the remaining water from the reservoir, Progress and its contractors
employed the following equipment and procedures:
• Progress employed a diesel powered four inch pump, with rigid four inch suction pipe
and four inch rigid suction pipe and four-ich lay flat discharge pipe. The pumping rates
during the dewatering ranged from approximately 200 gallons per minute (gpm) to 470
gpm. Please note, Progress and its contractors purposely pumped at a rate that would
not overwhelm the filtration media and the sanitary sewer system with the effluent,
therefore, the discharge rates were lower than the 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 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 its contractor evacuated approximately 689,000 gallons of water from the
reservoir. The water was pumped from the reservoir to a manhole located north of Building 11
(per above), subsequent to approval from Harnett County, and then to the Harnett County
Wastewater Treatment Plant. Following the removal of the water it was determined that the base
of the reservoir is not concrete, as suspected, but rather a sand rock material that is easily broken
using hand tools. This material is thin, no more than two to three inches thick. Beneath the sand
rock material is 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 drain pipe was determined to be intentionally mangled in an apparent effort to
prevent future flow. Progress also identified a manhole that appears 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 was formerly used to drain the water to the clarifier and had been 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. In addition, it was
noted that water was flowing through Manhole 64, to the pipe protruding into the
reservoir. Inspection downhole within Manhole 64 indicated one pipe extending northeast
towards Buildings 9 and 10. This pipe appears to have been grouted previously, with only a small
portion of the pipe diameter allowing water to flow. The water appears 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. Progress and Harnett County personnel noted sounds of water flowing in a
manhole located north of the reservoir and a drop inlet just north of the reservoir prior to
commencement of pumping. The source of the water in the pipe discharging to the reservoir

has not been determined. It may be stormwater flowing from the roof drains on the site buildings
as the flow appears to have been associated with precipitation events.
The site activities were inspected by Ms. Amanda Thompson of NCDEQ-Solid Waste Section during
the pumping of the water in the reservoir and based on Ms. Thompson's observation the material
that is visible in the cross-section of the fill material appears to meet the definition of beneficial
fill and can be left in -place. Ms. Thompson requested that Progress and its contractor use
mechanical means to remove and properly dispose 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, of the Solid Waste Section, indicated that this Work
Plan 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 also contacted Mr. Tim LaBounty of the Division of Energy, Mineral, and Land resources
(DEMLR) concerning the breaching of the dam. Mr. LaBounty provided Progress information used
to make determinations of required steps to take. According to information provided to Progress,
the pond does not meet the requirements to be considered a regulated dam under Dam Safety
jurisdiction as it is not both a 25 foot high dam and it does not contain more than 50 acre-feet of
water. Based on calculations it was determined that the volume of water within the dam is
approximately 16.66 acre-feet if the reservoir is full and the bottom of the reservoir were flat with
a constant depth of 20 feet. The dam slopes east to west and is significantly shallower than 20
feet on the eastern side. Mr. LaBounty also stated that the reservoir may be considered a
jurisdictional dam if it is considered a High Hazard Classification. Prior to breaching the dam,
Progress will complete and submit a Jurisdiction/Determination/Hazard Classification Requestto
evaluate if a dam is governed by the Dam Safety Law of 1967 (as amended). A Notice of
Exemption dated May 9, 2023 from the NCDEQ-DEMLR stated "Based on our reviews, analysis
and inspections, DEMLR has determined that a Class A, Low Hazard classification is presently
warranted due to the presence of woodlands and utilities downstream from the dam within the
potential breach inundation zone(s). Class A includes dams located where failure may damage on
inhabited low value non-residential buildings, agricultural land, or low volume roads." A copy of
this letter is attached.
Mr. LaBounty further indicated that Progress consider contacting the Army Corps of
Engineers/NCDEQ Division of Water Resources regarding the discharge of the flowing water to a
potential wetland area, stream, or surface water. For the purposes of this project, Progress
intends to pipe the flowing water to a former clarifier, located downgradient and west of the
reservoir. The clarifier will act as a retention pond to minimize impacts to a nearby stream. The
clarifier is depicted as a potential wetland area on the Hart and Hickman site maps, however, the
clarifier is a man made structure as part of the waste water treatment system formerly in use at
the site. Therefore, it is unlikely to be considered a jurisdictional wetland area by the regulatory
authorities.
Progress was met on site by Mr. Trent Allen of the NCDEQ Division of Water Resources (DWR)
regarding the piping of the discharge through the dam, and into a low lying area downgradient
of the reservoir. Mr. Allen indicated that the proposed approach was in compliance with DWR

rules and regulations and encouraged Progress to collect and test a sample of the discharge prior
commencing the planned approach. Specifically, Mr. Allen indicated that Progress include Per -
and Polyfluoroalkyl Substances (PFAS) in the analytes list. Progress collected a water sample
from the standing water within Manhole 64 located adjacent to the reservoir that is the source of
the water that flows into the reservoir during rainfall events.
Progress was contracted to collect and test soil samples from within the on -site reservoir and
from a nearby quarry that is a prospective source of import material for the quarry.
FIELD ACTIVITIES
Asbestos Containing Material Removal
Progress personnel supervised the removal of identified asbestos containing materials (ACMs)
within several debris piles located along the northern side of the reservoir. T&T Abatement
Contractor Services, Inc. (T&T) excavated the debris piles and transported the material under
chain -of -custody to the Dunn -Erwin Landfill, a permitted disposal facility. 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. Based on visual observations, it was determined that the wrapping is likely ACMs. T&T
re -mobilized to the site and removed the ACM on the piping and transported the material to the
Dunn-Ewin landfill for disposal. 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.
Based on the nature of the material beneath the pipes (construction debris and rubble), Progress
proposed to use a HEPA vacuum in this area (approximately 100 square feet) to remove any
residual ACMs from the pipe removal.
Progress and T&T remobilized to the site on August 1, 2023. The purpose of the re -mobilization
was to remove residual ACMs identified during sampling of the underlying material using hand
tools. The material beneath the pipes consisted of unpainted concrete slabs, concrete blocks,
and bricks, with minimal soil between the construction debris, therefore, a HEPA vacuum was not
used. The collected material was placed into garbage bags and properly sealed. Evidence of
materials with possible ACMs were not noted. 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
On May 4, 2023, Progress and 3D Environmental Investigations, LLC (3D) were on -site to advance
two soil borings within the on -site reservoir. 3D advanced the soil borings using a Geoprobe m,
which utilized the direct push drilling method.

Progress Project No. TWO700N. GW
Progress supervised the advancement of two soil borings to depths of 11 to 15 feet below land
surface using a Geoprobe. Progress attempted to collect continuous soil samples from the soil
borings; however, minimal sample was collected due to the nature of the fill material. Recovered
soil cuttings primarily consisted of broken concrete, bricks and other inert debris. Progress did
not note evidence of painted materials, metal, or suspected ACMs in the soil cuttings. Minimal
soil beyond the upper foot was recovered during the advancement of the soil borings. Multiple
soil borings were advanced in each soil sample location to confirm general uniformity to the
subsurface material. Progress collected two soil samples from each interval and placed one of
the samples into a zip lock baggie and the other into a four ounce glass jar. The nature of the
material collected from depth precluded the collection of samples to be analyzed for volatile
organic compounds (VOCs). Therefore, soil samples collected in the upper foot were collected
for analysis for VOCs from both borings. Composite samples from each boring were collected for
analysis for semi -volatile organic compounds (SVOCs), for Total Resource Conservation and
Recovery Act (RCRA) Metals, for hexavalent chromium, and for the presence of asbestos.
The soil samples were collected for analysis for VOCs using EPA Method 8260, SVOCs using EPA
Method 8270, Total RCRA Metals using EPA Method 6020, for hexavalent chromium using EPA
Method 7199 as well as for asbestos using polarized light microscopy (PLM). The laboratory was
instructed to report the results to the method detection limits.
For QA/QC purposes, one duplicate soil sample (SB-22) 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.
uar
Progress coordinated access to the Heidelberg Materials site located proximal to the Site in Erwin,
North Carolina. The proposed area of material to be imported to the Site is depicted on Figure
3. It is proposed to obtain fill material for the reservoir backfilling from the quarry. 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 four 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 five feet bls. Soil samples were
collected from the terminus of each soil boring for laboratory analysis. The soil samples were
collected for analysis for VOCs using EPA Method 8260, semi -volatile organic compounds SVOCs
using EPA Method 8270, Total 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 (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.

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
10

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

RE: Notice of Exemption
13th Street Dam
Harnett County
State Dam ID: HARNE-113
To the Dam Owner(s):
NORTH CAROLINA
Environmental Quality
This is in response to your latest submission dated April 11, 2023 and received on April 13, 2023 of a request
for a jurisdictional determination and hazard classification of the existing subject dam. Personnel from the North
Carolina Department of Environmental Quality's Division of Energy, Mineral, and Land Resources (DEMLR)
reviewed the submitted materials and performed independent analyses to evaluate the subject dam's hazard
potential. The existing dam height and maximum storage capacity are 13 feet and 7.66 acre-feet, respectively.
Based on our reviews, analyses and inspections, DEMLR has determined that a Class -A, Low Hazard
classification is presently warranted due to the presence of woodlands and utilities downstream from the dam
within the potential breach inundation zone(s). Class A includes dams located where failure may damage
uninhabited low value non-residential buildings, agricultural land, or low volume roads.
In order for a dam to be subject to the Dam Safety Law of 1967 (NCGS 143-215.23), the impoundment must be
both 25 feet in height or taller and impound 50 acre-feet or more or be located where failure will likely cause
loss of life or serious damage to homes, industrial and commercial buildings, important public utilities, primary
highways or major railroads. Since this structure is less than the required height, less than the required maximum
storage capacity, and there is no apparent severe potential damage to downstream areas, the subject dam as
proposed is exempt from requirements of the Dam Safety Law of 1967.
Nevertheless, the following comments are offered:
1. Our office encourages the owner of any dam to maintain their dam using the same standards as would be
applied if it were under the jurisdiction of the Dam Safety Law of 1967.
2. If the dam is modified such that it is 25 feet in height or greater as measured from the highest point on the
crest of the dam to the lowest point on the downstream toe and will impound 50 acre-feet or more at the
highest point on the crest of the dam, this dam will no longer be considered exempt. In this case, engineering
certification, along with record drawings and specifications will be required as well as application processing
fees.
3. If future downstream development occurs which would be impacted by a failure of the dam, then the hazard
classification may be reassessed and may change from Low to High hazard classification. Please note that
in accordance with NCGS 143-215.25A(a)(6), dams which are determined to be high hazard are subject to
the provisions of the Dam Safety Law of 1967 regardless of height or impoundment capacity.

131" Street Dam
HARNE-113
The Army Corps of Engineers and the Division of Water Resources of this Department should be contacted to
determine if additional permits are required. Also, the erosion and sediment control program having jurisdiction
should be contacted to determine plan approval requirements. In any case, sediment must be prevented from
entering the waters of the state or flowing onto neighboring property.
Should the subject dam change ownership, a "Change of Ownership of a Dam" form must be completed by the
new owner of the dam at the time of transfer in order to ensure the new owner receives important information
concerning the subject dam, and the former owner be released from liability. The form may be located on the
Dam Safety website at https://deq.nc.gov/about/divisions/energy-mineral-and-land-resources/dam-
safety/apalication-forms. The completed form must be submitted via email to dam.safety@ncdenr.g_ov listing the
change of ownership for the subject dam with its applicable state ID in the subject line.
There are additional guidance and resources available on the Dam Safety website at:
htti3s://deq.nc.g_ov/about/divisions/energy-mineral-land-resources/energy-mineral-land-permits/dam-safety
Also, to assist dam owners through outreach and education, the Association of State Dam Safety Officials' Owner
Outreach Committee has developed three educational videos as a free resource for owners on critical basics of
operating and maintaining a dam safely. The videos are 1) dam inspections, 2) spillways and outlet works, and
3) operation and maintenance plans. All the videos are available at: https://damsafety.org/dam-owners. These
videos are the first in a series specific to owner education called the 'Dam Owner Academy.'

Dear Customer:
Enclosed are asbestos analysis results for PLM Bulk samples received at our laboratory on
April 6, 2023. The samples were analyzed for asbestos using polarizing light microscopy
(PLM) per the EPA 600 Method.
Sample results containing >1 % asbestos are considered asbestos -containing materials
(ACMs) per EPA regulatory requirements. The detection limit for the EPA 600 Method is <1 %
asbestos by weight as determined by visual estimation.
Thank you for your business and we look forward to continuing good relations.

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.

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.

QUALIFIERS
Project: HPR NC - Erwin Part 2
Pace Project No.: 92665974
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
Batch: 916237
Ill Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
ANALYTE QUALIFIERS
1g Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
C9 Common Laboratory Contaminant.
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
J Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
