Brownfields Assessment Work Plan – Revision 1
Erwin Mill
200 North 13th Street
Erwin, North Carolina H&H Job No. BRP-001 1.0 Introduction
On behalf of Erwin Plant, LLC, Hart & Hickman, PC (H&H) is providing this Work Plan to
conduct Brownfields assessment activities at the Erwin Mill Brownfields property (Brownfields
Project No. 22058-18-043) located at 200 North 13th Street in Erwin, Harnett County, North
Carolina (Site). Erwin Mill (Parcel Identification No. [PIN] 0597-54-8405.000) consists of one
parcel of land that totals approximately 55.25 acres and is developed with multiple office
buildings, warehouse storage buildings, and former textile manufacturing buildings. The Site
historically operated as a textile manufacturing facility dating back to the early 1900s. Much of
the Site is currently vacant with the exception of several warehouse buildings that have been
leased to various tenants. A Site location map is provided as Figure 1, and the Site and
surrounding area are shown on Figure 2.
Erwin Plant, LLC was approved to work with the Brownfields Program under a “Ready for
Reuse” (RFR) Brownfields agreement, in which Erwin Plant, LLC will act as a proxy for a future
prospective developer (PD) to assess the Site as needed. This Work Plan has been prepared to
address data gaps in previous assessment work, as discussed during the March 7, 2019 Data Gap
meeting with the Brownfields Program.
1.1 Background
Erwin Mills began operation of a textile manufacturing facility at the Site in 1904. The facility
was primarily focused on the production of denim. Burlington Industries purchased the Site in
1962 and continued to operate the facility. Burlington Industries merged with Swift Textiles, Inc.
in 1987, and the facility continued to operate through 2000, when the property was purchased by

the current owner, Schwarz Auman Properties, LLC. Since 2000, the property has been
predominately vacant with the exception of several warehouse buildings that have been leased to
various tenants. Current or recent tenants include general small businesses, county offices,
warehouse users, and some light manufacturing (rifle assembly, ammunition assembly, and
cabinet shop).
1.2 Previous Assessment Activities
Prior sampling of soil and/or groundwater was performed at the Site during a 1997 Underground
Storage Tank (UST) closure, 1998 fuel oil removal in the area of the dye storage building, and
2001 Phase II Environmental Site Assessment (ESA). In addition, a Phase I ESA was conducted
in 2015. A brief discussion of previous assessment activities completed at the Site is provided in
the following sections.
1997 UST Closure Activities
In May 1997, EarthTech, Inc (EarthTech), oversaw the removal of one 2,000-gallon gasoline
UST and one 1,000-gallon diesel UST. Assessment activities completed during the UST
removal were documented in a June 9, 1997 GW/UST-12 UST Closure Report. Soil samples
were collected from the sidewalls and base of the UST basin following the removal of each UST,
as well as from stockpiled soil excavated during UST removal. Total petroleum hydrocarbons
(TPH) exceeded the North Carolina Department of Environmental Quality (NCDEQ) Action
Levels in soil samples collected from the base of the gasoline and diesel UST pits, as well as the
sidewall of the diesel UST pit. No additional assessment activities related to the UST release
were documented. The release incident was reported to the NCDEQ UST Fayetteville Regional
Office and assigned the incident number 19068. The incident is currently in the response phase.
1998 Fuel Oil Removal Activities
In February 1998, Trigon Engineering Consultants, Inc (Trigon) completed fuel oil removal
activities at the Site. The fuel oil removal activities were documented in a February 27, 1998
Progress Report of Fuel Oil Removal Activities. According to the report, fuel oil had been
3
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
observed in monitoring well MW-2, located inside the dye house. The thickness of the fuel oil
was three feet prior to removal activities. Over the course of four days, the well was pumped dry
repeatedly and then allowed to recharge until the thickness of the fuel oil had been reduced to
approximately two inches. Trigon estimated that a total of two gallons of fuel oil and 23 gallons
of impacted groundwater were removed from MW-2. Previous assessment activities related to
the fuel oil in the dye house area had reportedly been conducted in 1993 and 1994; however, no
documents from those assessments were identified or provided.
ECS 2001 Phase II ESA
In June 2001, ECS, LTD (ECS) completed soil and groundwater assessment activities at the Site.
The assessment activities were documented in a September 6, 2001 Phase II ESA. Sampling was
conducted to investigate areas of potential environmental concern identified during a site visit
and conversations with Swift Denim personnel.
As a part of field activities, four existing site monitoring wells downgradient of the dye house
(MW-7 through MW-10) were sampled, seven groundwater samples were collected via
direct-push technologies (DPT), in areas of concern throughout the Site, and soil samples and
wipe samples were collected adjacent to the 16 on-site transformers.
Groundwater sample results indicated that chloroform, benzene, and naphthalene were detected
in groundwater at concentrations above North Carolina 2L Groundwater Quality Standards
(2L Standards) in the southeastern portion of the site near the warehouse storage area and former
coal power plant. Chrysene was detected in groundwater above the 2L Standard in the northern
portion of the site near the former manufacturing buildings. Lead was detected in groundwater
above the 2L Standard in the vicinity of the former dye house. The polychlorinated biphenyl
(PCB) Aroclor-1260 and/or Aroclor-1254 were detected in composite soil samples within the
vicinity of five PCB-containing electrical transformers.

W&R 2015 Phase I ESA
Withers & Ravenel, Inc (W&R) conducted a Phase I ESA, dated March 27, 2015. W&R
identified the following recognized environmental conditions (RECs) in connection with the Site:
• Historical textile manufacturing operations;
• Contaminated soils associated with former USTs;
• PCB transformers;
• Backfilling the reservoir with demolition debris; and
• Waste drums remaining on-Site from plant operation.
The Site was occupied by a denim textile mill that utilized USTs and ASTs containing diesel,
gasoline, dyes, sulfuric acid, ammonia, and other petroleum and solvent based hazardous
materials. The mill operated since 1904 and typical processes included dyeing, sanforizing,
bleaching, finishing, and cleaning fabrics. Trench drains throughout the facility were piped to an
off-Site wastewater treatment facility. A large reservoir was utilized as a waste dye lagoon in the
southwestern portion of the Site. Vehicle and equipment maintenance areas were also present at
the Site and included activities such as welding. In addition, PCB-containing transformers have
been present on the Site throughout mill operations. Subsequent to the termination of textile mill
activities, equipment and materials were removed and several buildings were demolished.
Building demolition materials have been utilized to backfill the reservoir. W&R concluded that
there was significant potential for impact to the Site from historical activities.
H&H 2018 Assessment and Waste Disposal Activities
In May 2018, H&H conducted soil assessment activities at the Site to evaluate the potential
impacts of the former aboveground storage tanks (ASTs) to the south of the reservoir. In
July 2018, H&H collected a sample of tar-like material originating from a seam in the concrete
slab of the former cotton blending/opening building in the central portion of the Site. In addition,
H&H oversaw the characterization and removal of materials in the drum storage area in the
northern portion of the Site, as well as paint and related materials abandoned by a tenant
operating a paint recycling shop out of a warehouse in the southeastern portion of the Site. These
activities were documented in a September 21, 2018 Assessment & Waste Disposal Summary
Report.

\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
TPH diesel range organics (DRO) were detected at concentrations above the NCDEQ Action
Level in soil in the vicinity of the former 1,000,000-gallon heating oil AST and
two 150,000-gallon heating oil ASTs. Detected TPH DRO concentrations ranged from
295 mg/kg to 15,500 mg/kg. Two composite samples from the soil stockpile located at the
former 1,000,000-gallon fuel oil AST pad indicated concentrations of TPH DRO above the
NCDEQ Action Level and chromium above NCDEQ Preliminary Soil Remediation Goals
(PRSG). Semi-volatile organic compounds (SVOCs), including benzo[a]anthracene,
benzo[a]pyrene, benzo[b]fluoranthene, and indeno[1,2,3-cd]pyrene, were detected above
NCDEQ PSRGs in one of the soil stockpile composite samples. In addition, TPH DRO was
detected in a sample of tar-like material that was oozing up from a seam in the concrete slab of
the former cotton blending building at a concentration of 2,380 mg/kg.
1.3 Areas of Concern
Assessment activities, including assessment of groundwater, soil, sub-slab gas, surface water,
and sediment, have been developed based upon a review of Site history, prior chemical usage and
waste management, and previous assessment activities that have been conducted at the Site.
Based on our review of the available information, as well as discussions with the DEQ
Brownfields Program during the previously mentioned Data Gap meeting, potential areas of
concern (AOCs) were identified for further assessment. Each AOC and the rationale for further
assessment is described below.
AOC #1: Manufacturing Buildings
Operations performed in the manufacturing buildings included spinning, blending, carding,
beaming, dyeing, sanforizing, finishing, and inspections. The Phase I ESA also referenced
machine shops, welding, a carpenter shop, chemical storage and mixing areas, drum wash areas,
research and development lab areas, and shipping/receiving areas in the manufacturing buildings.
Chemicals would have been associated with many of these operations. Following shut-down of
the manufacturing facility, drums across the facility from various locations were consolidated
into a single drum storage area in one of the northernmost manufacturing buildings. Trench-style
6
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
floor drains are located in several of the buildings, which lead to a WWTP located approximately
0.5 miles southwest of the Site. The WWTP was formerly operated by the textile mill owners,
but is currently owned and operated by Harnett County and is not located on the Site property.
No assessment has been performed in the interior of the manufacturing buildings, other than
collection of wipe samples around two interior PCB transformers (discussed transformer
discussion below). Groundwater samples were collected at several locations around the exterior
of the manufacturing building during the 2001 Phase II ESA and analyzed for VOCs and SVOCs.
The results of the sampling indicated concentrations of 1,1-dichloroethane and chrysene at
concentrations exceeding 2L Standards. Due to the potential for releases from chemical use
during textile mill operations, additional groundwater, soil, and sub-slab gas assessment is
proposed in the manufacturing buildings.
AOC #2: Dye House and Former Dye House
The dye house contained subsurface stainless-steel vaults to store dyes used in the dyeing
process. Subgrade pits, heavily stained with dyes, were observed in the dye house. Drains in the
dye house lead to an adjacent reservoir (see reservoir discussion below). One historical
1925 Sanborn map also references a second dye house in the eastern portion of plant which has
not been assessed. The second dye house stopped operations prior to 1980.
Monitoring wells were installed in the area of the dye house in 1992 and 1993; however, reports
documenting the 1992-1993 investigation were not available to H&H. The 1998 Fuel Oil
Progress report indicated that free product was present in MW-2, located downgradient of the
dye pits. Free product was measured to be 1.2 feet thick in MW-2 during an April 2019 Site
visit. However, free product was not observed in wells MW-3 through MW-5. During the
2001 Phase II ESA, samples were collected from the downgradient monitoring wells (MW-7
through MW-10) for analysis of VOCs, SVOCs, and metals. The results of the sampling
indicated arsenic, chromium, and lead at concentrations above 2L Standards. These detections
may be associated with metals present in the dyes used in the manufacturing operation or natural
background conditions. Due to the presence of free product and previous detections of metals
7
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
downgradient of the dye house, as well as the potential for releases from dying activities in the
second dye house, additional groundwater, soil, and sub-slab gas sampling is proposed in the area
of the dye houses.
AOC #3: Warehouse Buildings
Four sets of warehouse buildings are located in the southwestern portion of Site. These
warehouses were used primarily for cotton storage, which does not generally represent an
environmental concern. However, the warehouses were also used for garage space, dye storage,
battery charging locations, truck and equipment maintenance activities, and storage of virgin and
waste automobile fluids. Additionally, former train spurs entered the Site in the area of the
warehouses, primarily to off-load coal for the coal-fired power plant.
Groundwater samples were collected in the area of the warehouse buildings during the
2001 Phase II ESA and analyzed for VOCs and SVOCs. The results of the sampling indicated no
exceedances of 2L Standards except for chloroform. The 2L Standard for chloroform has
increased since the date of the Phase II ESA and the detections are below the current standard.
Based on the potential for releases from historic uses within the warehouse buildings, additional
soil and sub-slab gas assessment is proposed within the warehouse storage buildings.
AOC #4: Reservoir
A reservoir was constructed at the site in approximately 1903. It is reportedly 20 feet deep and
lined with concrete. The reservoir was initially used to store water for the fire suppression
system, but was converted to waste dye storage. The reservoir was used to control amount of
waste dyes released to the WWTP. After the property was purchased by Schwarz Auman, the
reservoir was partially filled with building demolition debris. The demolition debris was
generated during the demolition of the coal fired power plant, former cotton blending/opening
building, a warehouse, and the dye house storage building. The reservoir is located in the same
general area as the dye house, so heavy metals detected in the dye house area discussed above
may also be present at the reservoir. Placement of building demolition debris in the reservoir
also represents a potential concern. If the building demolition debris contained no hazardous
materials, then placement of the debris in the reservoir may be acceptable. However, depending
8
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
on the source for the debris, the potential exists for hazardous substances to be in the debris.
Based on the historical use for storing waste dyes and current present of demolition debris,
additional surface water, sediment, and demolition debris assessment is proposed within the
reservoir.
AOC #5: Polychlorinated Biphenyl (PCB) Transformers
A total of 33 pad-mounted transformers were present across the Site historically. A total of
16 transformers contained PCB-laden oils, while the remaining 17 transformers utilized
PCB-free oils. The current property owner removed four of the PCB transformers, but 12 remain
at the Site. An electrical substation is also located at the Site, but the substation is owned by
Duke Energy. The remaining transformers were owned by the Site property owner.
A total of 14 hand auger borings were advanced adjacent to PCB-containing transformers during
the 2001 Phase II ESA. Samples were screened using a PID, which indicated elevated readings
(greater than 1,999 parts per million) in several locations. Samples were also submitted for
laboratory analysis of PCB Arochlors by EPA Method 8082. Arochlor concentrations exceed the
current Residential and Industrial PSRGs in multiple locations. Based on the presence of
Arochlors in the area of PCB transformers, soil assessment for PCB congeners is proposed at the
PCB transformers with the greatest exceedances.
AOC #6: Coal Fired Power Plant
A coal fired power plant was located in the central portion of the Site. The coal fired power plant
was demolished after the property was purchased by Schwarz Auman. Coal was delivered via a
rail spur, then the coal was stored in open coal storage area next to the tracks and two silos next
to boiler house. Coal ash was stored in a silo adjacent to the boiler house then hauled to a
landfill for disposal. One groundwater sample was collected in the area of the coal storage area
during the 2001 Phase II ESA. The sample was analyzed for VOCs and SVOCs; however, the
samples were not analyzed for metals, which represent the primary concern for this source area.
Based on the potential releases associated with the coal fired power plant and coal storage areas,
soil assessment is proposed for the coal fire power plant.

\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
AOC #7: Fuel Oil Boiler Building
A fuel oil boiler building was located in the central portion of the Site, adjacent to the former
coal fired power plant. One caustic soda AST (size unknown) and several smaller ASTs with
unknown content (likely fuel oil) were present in the fuel oil boiler building. A portion of the
building was demolished after the property was purchased by Schwarz Auman.
One groundwater sample was collected in the fuel oil boiler building during the 2001 Phase II
ESA. The sample was analyzed for VOCs and SVOCs. Concentrations of benzene and
naphthalene were detected above the 2L Standard. Based on the potential for releases from
former fuel oil use and the presence of petroleum-related constituents, additional soil and
groundwater assessment is proposed for the fuel oil boiler building.
AOC #8: Underground Storage Tanks (USTs)
One 2,000-gallon gasoline UST and one 1,000-gallon diesel UST were removed from the Site in
1997. Soil samples collected from the sidewalls and base of the UST basin following the
removal of each UST, as well as from stockpiled soil excavated during UST removal, indicated
exceedances of regulatory standards. The release incident was reported to the NCDEQ UST
Fayetteville Regional Office and assigned the incident number 19068. The incident is currently
in the response phase. One gasoline AST and one diesel AST (sizes unknown) replaced the
USTs. One groundwater sample collected in the vicinity of the ASTs and USTs during the
2001 Phase II ESA indicated no exceedances of 2L Standards for VOCs or SVOCs. Based on the
presence of petroleum-related constituents following the UST removal activities and active status
of the release incident, additional soil assessment is proposed for the former UST area.
AOC #9: Aboveground Storage Tanks (ASTs)
A total of 35 ASTs was used at the Site. All of the ASTs have reportedly been removed except
for a 450,000-gallon tank used to store water along the northern edge of the Site. Areas where
multiple ASTs were located in proximity to each other have been designated as separate AOCs as
discussed further below. Note that the ASTs referenced below do not include tanks that are not
considered a concern due to non-hazardous or gaseous contents. These ASTs include a
450,000-gallon tank used to store water along the northern edge of the Site, a
10
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
100,000-gallon water tank located north of the reservoir, six 30,000-gallon liquid propane tanks
located south of the reservoir, one liquid carbon dioxide tank (size unknown) located south of the
reservoir, six tanks containing unknown compressed gases (size unknown) located east of the
reservoir, and one propane tank located south of the boiler house.
AOC #9a: Reservoir Area ASTs - Multiple ASTs were located in the reservoir area, including a
1,000,000-gallon #6 fuel oil tank located south of the reservoir, two 150,000-gallon #6 fuel oil
tanks located south of the reservoir, a 100,000-gallon #2 fuel oil tank located north of the
reservoir, three indigo dye tanks (size unknown) located north of the reservoir, two brine tanks
(size unknown) located north of the reservoir, and three tanks with unknown contents (size
unknown) located north of the reservoir.
Groundwater samples were collected in the general area of the reservoir during the 2001 Phase II
ESA and analyzed for VOCs, SVOCs, and metals. The results of the sampling indicated
concentrations of heavy metals above 2L Standards, but no concentrations of VOCs or SVOCs at
concentrations above 2L Standards. Soil samples collected in the vicinity of the former #6 fuel
oil tanks to the south of the reservoir indicated exceedances of the NCDEQ action levels for TPH
DRO. Based on the previous detections of metals and petroleum-related constituents in the area
of the reservoir ASTs, additional soil and groundwater assessment is proposed.
AOC #9b: Northern ASTs - Two anhydrous ammonia and three ammonium hydroxide tanks
(sizes unknown) were located along the northern edge of the Site. No assessment has been
performed to evaluate for releases of ammonia from these tanks. Based on the potential for
releases from these ASTs, soil assessment is proposed in the vicinity of the ASTs.

AOC #10: Downgradient Receptors
Several drainage ditches, a potential wetland area, and an intermittent, unnamed tributary to
Juniper Creek are located on the Site. These water bodies are downgradient of former mill
operations. No surface water or sediment assessment has been performed to evaluate for releases
to these areas. Based on the potential for impacts from former mill operations, groundwater,
surface water, and sediment assessment are proposed for areas downgradient of potential sources.
Our detailed proposed scope of work is outlined in the following sections.

\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
2.0 Brownfields Assessment Scope of Work
The proposed assessment activities will be performed in general accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines)
dated October 2015, the DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance (VI Guidance) dated March 2018, and most recent versions of the U.S. Environmental
Protection Agency (EPA) Region IV Science and Ecosystem Support (SESD) Field Branches
Quality System and Technical Procedures guidance.
Prior to conducting the field activities, H&H will contact North Carolina 811, the public utility
locator, to mark subsurface utilities located on the Site. H&H will also contract with a private
utility locator to screen proposed sample locations for subgrade utilities that may not be marked
by the public locator. Lastly, prior to conducting the assessment, H&H will prepare a
site-specific Health and Safety Plan in accordance with Occupational Health and Safety
Administration (OSHA) requirements.
2.1 Brownfields Receptor Survey
H&H will perform a Brownfields receptor survey in accordance with DEQ Brownfields Section
guidance. The receptor survey will utilize the Brownfields Property Receptor Survey Form and
will include information about land use in the Site area including zoning. H&H will also conduct
a field search for water supply wells, basements, utility manways and chases, storm sewers, other
underground utilities, drains, and surface water within a 1,500 ft radius of the Brownfields
property boundaries.
2.2 Monitoring Well Installation Activities
H&H proposes to install ten permanent Type II groundwater monitoring wells to identify any
constituents in areas of concern and evaluate current conditions in historically impacted areas.
13
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
Proposed monitoring well locations are depicted on Figure 3, and described below. Table 1
provides details on sampling rationale and sample analyses.
• North of the ammonia finishing building on the northern portion of the Site and in the
vicinity of waste water sewer system effluent for the Site;
• East of the ammonia storage and compressor area in the northern portion of the Site
where previous 1,1-dichloroethane detections were located;
• Alongside trench drains located within the finishing building in the central portion of the
Site;
• Within the fuel oil boiler building where previous benzene and naphthalene detections
were located;
• Within the former chemical storage area northeast of the reservoir where fuel oil, dyes
and unknown chemicals were located and where previous metal detections were located;
• Northwest of the reservoir where waste dye was discharged into the waste water sewer
system for transport to the off-Site WWTP;
• West of the warping building on the western portion of the Site and in the vicinity of the
waste water sewer system effluent for the Site; and
• Downgradient of the dye house, reservoir, and fuel oil ASTs and upgradient of the
unnamed tributary to Juniper Creek.
Each monitoring well will be installed utilizing hollow stem auger drilling methods by a licensed
NC driller. During drilling, soil samples will be collected and logged for lithologic description
and field screened for presence of staining and elevated concentrations of volatile organic vapors
using a PID. The monitoring wells will be constructed in accordance with the North Carolina
well construction regulations. The monitoring wells will be constructed of 2-inch diameter PVC
with 10 ft of well screen set to bracket the water table and 2-inch diameter PVC well casing to
the ground surface. All monitoring wells within the fenced or paved areas of the Site will be
completed flush with the ground surface within flush mount manholes secured with 2 ft by
2 ft concrete pads. All monitoring wells located in highly vegetated areas outside the fenced
14
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
areas of the Site will be completed above the ground surface within above ground steel protective
covers.
Following installation, the new monitoring wells will be developed utilizing bailers and/or
pumps by removing a minimum of 3 to 5 well volumes and observing stable field parameters (i.e.
pH ± 0.1 SU and conductivity varies no more than 5%). Development water and drill cuttings
will be containerized in 55-gallon drums, as discussed in Section 4.0.
Following well installation activities, the horizontal and vertical locations for all of the Site
monitoring wells will be surveyed by a North Carolina licensed surveyor.
2.3 Groundwater Sampling Activities
Following monitoring well installation, groundwater samples will be collected from the newly
installed monitoring wells and existing Site monitoring wells MW-2 through MW-5. Prior to
groundwater sample collection, each monitoring well will be tested for the presence of free
product utilizing a decontaminated oil/water interface meter. If free product is observed within
any of the monitoring wells, the thickness of free product will be recorded and a groundwater
sample will not be collected. If free product is not observed, a groundwater sample will be
collected utilizing low flow/low stress purging techniques using a peristaltic pump and dedicated
polyethylene tubing. The intake point of the pump tubing will be placed approximately in the
mid-portion of the screened interval of the well and groundwater will be removed at a rate no
greater than 200 milliliters per minute. H&H will utilize a water quality meter to measure pH,
temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity
at 3 to 5-minute intervals during purging. Purging will be considered complete when water
quality parameters stabilize (i.e. pH ± 0.1 SU, conductivity varies no more than 5%, and turbidity
is less than 10 NTUs).

Once groundwater parameters stabilize, groundwater samples for VOCs analyses will be
collected directly into laboratory supplied sample containers using the “soda straw” method to
eliminate the potential for volatile loss through the peristaltic pump head. Samples for SVOCs
and metals will be collected directly into the containers through the peristaltic pump. The sample
containers will be labeled with the sample identification, date, and requested analysis, and placed
in a laboratory supplied cooler and iced. The samples will be delivered to a North Carolina
certified laboratory under standard chain of custody protocols for analysis of VOCs by EPA
Method 8260B, SVOCs by EPA Method 8270D SIM, and Resource Conservation and Recovery
Act (RCRA) metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver)
plus hexavalent chromium by EPA Methods 6020/7471B/7196A.
2.4 Soil, Debris, and “Tar-Like” Material Assessment Activities
H&H proposes to conduct soil assessment activities to evaluate current subsurface conditions for
potential impacts. H&H will team with a qualified drilling contractor to advance soil borings to
depths ranging from approximately 5 to 15 ft bgs. Proposed soil sample locations are depicted
on the sample location map, which is presented as Figure 4.
Prior to advancing soil borings, the boreholes will be cleared for utilities by hand auger to a depth
of 5 ft bgs. The soil borings will be advanced utilizing a track-mounted direct push technology
(DPT) drill rig. Continuous soil samples will be collected from the borings using acetate lined
macrocore sleeves. Soil samples will be logged for lithological description and field screened for
indication of potential impacts by observation for staining, and the presence of organic vapors
using a calibrated PID. Up to two soil samples will be collected from each soil boring, unless
otherwise stated. The proposed sampling depths of each sample is summarized on Table 2.
One sample will be collected at the surficial soil (0-1 ft bgs) interval and one soil sample will be
collected from each soil boring from the subsurface (>1 ft bgs) depth interval interpreted most
likely to be impacted based on field observations and PID readings. If there are no obvious
indications of potential impact based on field screening results, then the subsurface soil sample
will not be collected.

\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
Following collection, the soil samples will be placed in dedicated laboratory-supplied sample
containers, labeled with the sample identification, date, and requested analysis, and placed in a
laboratory supplied cooler with ice. Soil samples will be submitted to a North Carolina certified
laboratory under standard chain of custody protocols for analyses as referenced in Table 2 and
summarized below:
• Up to two samples will be collected from 28 borings advanced in the dye houses, shop
area, warehouses, research and development lab, former chemical storage area, coal fired
power plant, fuel oil boiler building, former UST locations, and the former
1,000,000-gallon and 150,000-gallon fuel oil ASTs. The samples will be submitted for
analysis of VOCs by EPA Method 8260B, SVOCs by EPA Method 8270D, and RCRA
metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) plus
hexavalent chromium by EPA Methods 6020/7471B/7196A.
• Up to two soil samples will be collected from two soil borings advanced in the ammonia
storage/compressor area. Soil samples will be submitted for analysis of ammonia by EPA
Method 4500 and nitrate and nitrite by EPA Method 300.0.
• Three soil samples will be collected at a depth of 4 ft bgs from soil borings advanced in
the vicinity of the three former PCB transformers with the highest concentrations of
previous PCB detections. Soil samples will be submitted for analysis of PCB congeners
by EPA Method 1668A.
• Up to eight soil samples will be collected from background locations at the site. The soil
samples will be submitted for analysis of RCRA metals plus hexavalent chromium by
EPA Method 6020/7471B/7196A.
Following sampling activities, borings will be properly abandoned and the surfaces will be
repaired similar to pre-drilling conditions. Additionally, exterior soil sample locations will be
estimated using a hand-held global positioning system (GPS) unit and interior sample locations
will be estimated by measuring from known benchmarks (e.g. doorways, walls, etc.).
17
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
In addition, H&H will collect debris samples from two locations inside the reservoir and
one sample of the “tar-like” material observed at the seam in the concrete slab of the former
cotton blending building. Debris samples will be collected by advancing a decontaminated
stainless-steel hand auger into the reservoir material until demolition debris is encountered. A
debris sample will be collected and placed in dedicated laboratory-supplied sample containers,
labeled with the sample identification, date, and requested analysis, and placed in a laboratory
supplied cooler with ice. The “tar-like” material will be collected directly into a dedicated
laboratory-supplied container. Debris and “tar-like” material samples will be submitted to a
North Carolina certified laboratory under standard chain of custody protocols for analysis of
VOCs by EPA Method 8260B, SVOCs by EPA Method 8270D, RCRA metals plus hexavalent
chromium by EPA Method 6020/7471B/7196A. The debris samples will also be submitted for
analysis of asbestos as bulk material by polarized light microscopy (PLM) by EPA Method 600.
2.5 Sub-Slab Gas Assessment Activities
H&H proposes to install and sample temporary sub-slab gas monitoring points to evaluate the
potential for vapor intrusion at the Site. A total of 29 sub-slab gas samples will be collected
throughout the Site, with a higher sampling density in areas of concern (i.e. machine shop, dye
houses, finishing building). If preferential pathways, such as sewer liners, are known to be
present within a sample area, the sub-slab monitoring point will be installed adjacent to those
pathways. The proposed sub-slab gas sample locations are shown on Figure 5. Sample IDs,
locations, rationale and analyses are provided on Table 3.
H&H will install a Cox-Colvin Vapor Pin® (vapor pin) at each proposed sub-slab gas sample
location. For installation of the vapor pin, a hammer drill with a 5/8-inch diameter bit will be
utilized to penetrate the concrete slab with a drilled pilot hole. The vapor pin assembly
(sampling point and silicone sleeve) will then be placed into the pilot hole and secured using an
installation/extraction tool and a “dead blow” hammer to form an air-tight seal. Once the vapor
pin assembly has been secured in the pilot hole, ¼-inch diameter Teflon® sample tubing will be
attached to the vapor pin assembly sample port barb. During the vapor pin installation, H&H
will document encountered material present immediately beneath the concrete slab, i.e. gravel,
sand, clay, etc.
18
\\HHFS01\MasterFiles\AAA-Master Projects\Brooks Pierce\Erwin Mill (BRP.001)\Brownfields Assessment Work Plan\REV 1 to DEQ\Brownfields Assessment Work Plan Rev 1_Erwin Mill_(BPN 22058-18-043).doc
After installation of the vapor pins and prior to sample collection, a leak check will be conducted
at each sample location by constructing a shroud around the sampling point, sampling fittings,
and sampling connections, and flooding the air within the shroud with helium gas. Helium
within the shroud will be monitored using a helium gas detector. Using a syringe and a
three-way valve, the sample point will be purged. A sub-slab gas sample will then be collected
outside of the shroud into a Tedlar® bag and analyzed using the helium gas detector to ensure that
helium concentrations are less than 10% of the concentration in the shroud.
Following a successful leak check, sub-slab gas samples will be collected in laboratory-supplied
1 liter (or greater volume) stainless steel Summa canisters connected to in-line flow controllers
with a laboratory calibrated vacuum gauge. The flow controller will be connected to the sample
tubing at each sampling point using a brass nut and ferrule assembly to form an air-tight seal.
The flow regulator will be pre-set by the laboratory to regulate the intake rate to approximately
100 milliliters per minute. Once the sample train is assembled, the intake valve on the canister
will be fully opened to begin collection of the sub-slab gas sample. Vacuum readings on the
Summa canister will be recorded prior to and following the sampling period to ensure adequate
sample volume was collected. A vacuum will be maintained within the canisters at the
conclusion of the sampling event. To evaluate the reproducibility of the sample results,
two duplicate sub-slab gas samples will be collected using a laboratory-supplied T-sampler
which allows collection of two samples from a single sample port simultaneously.
Upon completion of sample collection, each Summa canister’s valve will be closed and the
regulator will be disconnected from the canister. The canisters will be placed in
laboratory-supplied shipping containers, properly labeled, and shipped under standard
chain-of-custody protocols to a qualified laboratory for analysis of volatile organic compounds
(VOCs) by EPA Method TO-15.
Upon completion of sampling activities, the sub-slab gas sample points will be abandoned and
the surface will be repaired similar to pre-drilling conditions. Each sample location will be
estimated by measuring from known benchmarks (e.g. doorways, walls, etc.).

2.6 Surface Water and Sediment Assessment Activities
H&H proposes to collect six co-located surface water and sediment samples for laboratory
analysis from the reservoir, potential wetland area downgradient of the reservoir, and the
downgradient unnamed tributary to Juniper Creek. Co-located surface water and sediment
sample locations are shown on Figure 6. If necessary, H&H will utilize a small boat to access the
sampling location in the reservoir. H&H will utilize water quality meters to collect
measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and
specific conductivity of surface water at each sample location.
Surface water will be collected directly into laboratory-supplied sample containers. Sediment
samples will be collected from the base of the surface water body at each sample location using a
decontaminated stainless steel AMS dredge sampler or other suitable method. The sample
containers will be labeled with the sample identification, date, and requested analysis, and placed
in a laboratory supplied cooler and iced. The surface water and sediment samples will be
delivered to a North Carolina certified laboratory under standard chain of custody protocols for
analysis of VOCs by EPA Method 8260B, SVOCs by EPA Method 8270D SIM, and RCRA
metals plus hexavalent chromium by EPA Methods 6020/7471B/7196A.
Upon completion of sampling, the co-located surface water and sediment sample locations will
be estimated using a hand-held GPS unit.

3.0 Quality Assurance / Quality Control
Laboratory quality assurance/quality control (QA/QC) procedures will be employed to ensure
appropriate sample handling and analysis and to aid in the review and validation of the analytical
data. QA/QC procedures will be conducted in accordance with DEQ and EPA method protocols
and will include regular equipment maintenance, equipment calibrations, and adherence to
specific sample custody and data management procedures. In accordance with approved
methodologies, samples will be analyzed in conjunction with appropriate blanks, laboratory
duplicates, continuing calibration standards, and surrogate standards to monitor both instrument
and analyst performance. H&H will request that the laboratory reporting limits for each analyte
will be at or below appropriate screening criteria. Additionally, H&H will request that the
laboratory include J Flags, which are estimated concentrations for compounds that are detected at
levels above the laboratory method detection limits, but below the laboratory reporting limits.
The following activities will be conducted by H&H for QA/QC purposes:
• non-dedicated equipment and tools will be decontaminated prior to use at each boring or
sampling location, or following exposure to soil or groundwater. A rinseate blank will be
collected per sample equipment type per matrix during assessment activities;
• one duplicate sample will be collected per every 20 samples per sampling media per
analytical method during assessment activities;
• one MS/MSD sample will be collected per every 20 samples per sampling media per
analytical method during assessment activities; and
• one trip blank per shipment will accompany groundwater and surface water samples
during field and shipping activities. The trip blank will be analyzed for VOCs by EPA
Method 8260B.
Laboratory analyses for proposed QA/QC sampling is referenced in Table 1. A copy of the
laboratory analytical data report and QA package for each group of samples submitted to and
analyzed by the subcontracted laboratory will be provided in an appendix to the final report.

4.0 Investigative Derived Waste
Investigation derived waste (IDW) generated during the assessment activities will be
containerized and characterized. The IDW anticipated to be generated during assessment
activities includes soil cuttings, purge water, and decontamination water. This IDW will be
containerized in 55-gallon drums pending off-Site disposal. A composite soil sample of the IDW
soil drums will be collected and submitted for laboratory analysis of toxic characteristic leaching
procedure (TCLP) VOCs by EPA Method 8260, TCLP SVOCs by EPA Method 8270, and TCLP
RCRA Metals by EPA Method 6010/6020. A composite water sample of the IDW liquid drums
will be collected and submitted for laboratory analysis of VOCs by EPA Method 8260, SVOCs
by EPA Method 8270, and RCRA metals by EPA Method 6010/6020. The IDW will be properly
disposed at an off-Site facility based on the analytical results.
