Minimum Requirements Checklist
for
Site Assessment
Work Plans and Reports
NCDEQ Brownfields Program – February 2022
Instructional Page
All references to Prospective Developers includes follow-on owners who may be conducting
work in accordance with the Brownfields Property Management Unit.
To increase predictability and most efficiently assess Brownfields Properties and the
redevelopment timing requirements of Prospective Developers or follow-on owners, the
Brownfields Program has standardized the format for Site Assessments. This format has been
generated in the form of a checklist to allow for ease in submission by the prospective developer’s
consultant and for the Brownfields Program’s completeness review. This checklist outlines the
minimum requirements and submittal format under the Brownfields Program for Assessment
Requirements and Reporting. All Assessment Work Plans and Reporting submissions to the
Brownfields Program must include this completed checklist in the outlined format.
These requirements allow DEQ to reduce review time for the Assessment Work Plan and Report
and increase process predictability for prospective developers. This checklist will also provide
reliable data for risk-based decisions and further expedite the project timeline. Any divergence
from these requirements will lengthen the process of assessing risks on the site, may necessitate
reprioritization of a project manager’s queue towards projects that meet these requirements.
Therefore, delaying production of the brownfields agreement and/or environmental management
plan. Any alterations to the checklist on a site- specific basis must be reviewed and approved by
the Program prior to implementation. However, in order to respect the schedule of all projects in
house and keep the program’s entire project pipeline moving, we strongly recommend against
seeking changes to the checklist.
Based on a review of environmental and risk data from our project inventory, please note
there are some new points of emphasis that are included herein:
1. For ALL residential reuses; sub-slab vapor assessment (full list EPA TO-15) is required,
regardless if existing structures will be removed. If no structures or slabs exist on the
Brownfields Property, exterior soil gas assessment is required within all proposed
structure footprints. 
2. ALL properties require groundwater data (VOCs, SVOCs and RCRA Metals) from a
minimum of three sample locations, depth to groundwater and a resulting potentiometric
map. 
3. Soil shall be assessed based on areas of concern and redevelopment plans and across the
depth interval of the cut/grading.

Brownfields Assessment Work Plan
Eastway Plaza
The Plaza and Eastway Drive
Charlotte, North Carolina
Brownfields Project No. 22044-18-060
H&H Job No. WPP-019

1.0 Introduction

On behalf of 10290, Ltd., 4525 LLC, and SPCP Group III LOPD31, LLC (Prospective
Developer or PD), Hart & Hickman, PC (H&H) has prepared this Brownfields Assessment Work
Plan (Work Plan) for the Eastway Plaza Brownfields property (Brownfields Project No. [BPN]
22044-18-060) located northeast of The Plaza and Eastway Drive intersection in Charlotte,
Mecklenburg County, North Carolina (Site). The Site consists of three contiguous parcels
(Mecklenburg County Parcel Identification Nos. 09713101, 09713199, and 09713106) that
collectively total approximately 25 acres of land located in a mixed residential and commercial
use area of Charlotte. A Site location map is provided as Figure 1, and the Site and surrounding
area are shown in Figure 2.

The northern portion of the Site is developed with a multi-tenant retail shopping center
constructed in the late 1960s with building additions constructed in the 1970s. The Site
buildings have historically been occupied by various retailers, churches, and an auto repair
facility. The southern portion of the Site operated as a 60 Minute Cleaners from at least the late
1960s until the early 1990s. The 60 Minute Cleaners facility was entered into the North Carolina
Department of Environmental Quality (DEQ) Dry-Cleaning Solvent Cleanup Act (DSCA)
Program in October 2015 (DSCA Project No. DC600024). Remaining portions of the Site
consist of undeveloped wooded land and asphalt paved vehicle access and parking areas.

Proposed redevelopment of the Brownfields property includes razing the existing Site buildings
for construction of an apartment complex, for-rent townhomes, and commercial retail and/or
office space with associated parking areas and access roads. The proposed Site plan is shown in
Figure 3.

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
1.1 Background Information

The Site was primarily utilized for agricultural purposes as early as the late 1930s. In the late
1940s, the northern portions of the Site were cleared and developed with a portion of a racetrack.
By the 1950s, the central portion of the Site was developed with a rural residence and
agricultural use structures. From the late 1960s until the early 1970s, the main shopping center
retail buildings, a free-standing restaurant, a free-standing theatre, and a drycleaner (60 Minute
Cleaners) were developed on the Site. The anchor retail building was originally occupied by
Zayre department store but was also occupied by Eastway Auto Center in at least the 1980s.
Other occupants primarily consisted of grocery stores, barber shops, salons, retail stores, and
restaurants. Site conditions remained unchanged until the mid-1990s, when the 60 Minute
Cleaners building located in the southern portion of the Site was demolished.

1.2 Previous Assessment Activities

To obtain additional information, H&H reviewed several reports prepared by others to document
previous environmental assessments completed at the Site. Pertinent historical documentation is
included in Appendix A, and a brief summary of the information available in the environmental
reports is provided below.

Former 60 Minute Cleaners
The southern portion of the Site (4447 The Plaza) was historically occupied by 60 Minute
Cleaners from at least the late 1960s through the early 1990s. Historical dry-cleaning operations
have resulted in groundwater, soil, and exterior soil gas impacts. Based on the results of
assessment activities, the Site was entered into the DEQ DSCA Program (Project ID No.
DC600024). In 2018, two co-PDs (4545, LLC and SPCP Group III LOPD 3, LLC) became the
DSCA Program petitioners for the 60 Minute Cleaners facility.

Based on information provided in a 2005 Prioritization Assessment Report prepared for Site,
multiple release incidents have been reported for adjacent and nearby properties that have
resulted in a co-mingled contaminated groundwater plume. The former Dutch Cleaners facility
3

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-019 eastway
plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
(DSCA Project ID No. DC600088) was located on the southern adjoining property and operated
from the 1960s until the 1990s. The former Northeast Plaza Launderette facility was also located
on the southern adjoining property and operated from the 1960s until the 1990s. The Eastway
Drive and The Plaza solvent release incident (NONCD0002960) is identified on the Inactive
Hazardous Sites Branch (IHSB) Inventory List and is also contributing to the co-mingled
groundwater plume. Assessment and risk evaluation activities have been conducted at the
former 60 Minute Cleaners property under the purview of the DSCA Program from 2005 until
the present.

Results of soil sampling activities completed at the Site by the DSCA Program in 2005 and 2020
identified the dry-cleaning solvents PCE (up to 0.18 milligrams per kilogram [mg/kg]) and TCE
(up to 0.23 mg/kg) at concentrations above the DEQ Protection of Groundwater Preliminary Soil
Remediation Goals (PSRGs), but below the DEQ Residential PSRGs in the vicinity of the former
60 Minute Cleaners facility.

Results of groundwater sampling activities completed in 2016 identified PCE (up to 1,100
micrograms per liter [µg/L]), trichloroethylene (TCE; up to 645 µg/L), 1,2-dichloroethene (up to
295 µg/L), and vinyl chloride (up to 1.5 µg/L) at concentrations above the North Carolina
Administrative Code (NCAC) 15A 2L Groundwater Standards (2L Standards) in groundwater
samples collected in the vicinity of and downgradient of the 60 Minute Cleaners facility.
Additional 60 Minute Cleaners assessment activities completed by the DSCA Program have
included installation and monitoring of on- and off-Site permanent groundwater monitoring
wells, and vapor intrusion evaluation on-Site and on multiple nearby off-Site properties located
south and downgradient of the 60 Minute Cleaners facility.

Results of recent vapor intrusion assessment activities completed at the former 60 Minute
Cleaners facility in December 2020 identified PCE (737 micrograms per cubic meter [µg/m3]) at
a concentration above the DEQ Residential Vapor Intrusion Soil Gas Screening Level (SGSL) of
280 µg/m3. However, the results of cumulative risk calculations did not exceed the unacceptable
thresholds under residential or non-residential use scenarios.

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
In 2018, soil gas assessment activities associated with the former Dutch Cleaners facility (DSCA
Project ID No. DC600088) were completed in the southern portion of the Site. Results of the
2018 assessment identified PCE (up to 2,030 µg/m3) in soil gas in the southern portion of the
Site at a concentration above the DEQ Residential and Non-Residential Vapor Intrusion SGSLs.
Based on information provided in available environmental documents, the former Dutch
Cleaners release incident will be closed with the implementation of land use restrictions. H&H
understands that certain land use restrictions associated with the former Dutch Cleaners release
incident will also be implemented for the Site, and a vapor intrusion land use restriction will
apply to an approximate 2,000 square foot area of the Site where PCE was detected in soil gas at
concentrations above the DEQ Vapor Intrusion SGSLs during the 2018 soil gas assessment.

2001 Phase I ESA
In May 2001, Danner Companies, LLC t/a Salem Environmental completed a Phase I
Environmental Site Assessment (ESA) for the northern Site parcel. Results of the Phase I ESA
identified the following recognized environmental conditions (RECs) in connection with the
Site:

 The commercial retail shopping center located in the northern portion of the Site was
occupied by Eastway Auto Repair (401 Eastway Drive). Eastway Auto Repair operations
included use of in-ground hydraulic lifts, storage of new and used oils, and other
automotive products since 1968. Results of the Phase I ESA identified the potential for
impacts to the Site from historical auto repair operations as an REC.

 The property located adjacent to the retail shopping center parcel was identified as Joe
Harris Dry Cleaners (4447 The Plaza). A release of drycleaning solvents was reported in
connection with the facility. Results of the Phase I ESA identified the documented
release associated with drycleaning operations on the adjacent parcel as a REC.

 Results of the Phase I ESA identified documented release incidents associated with gas
stations located at 4405 The Plaza (Crown Station), 601 Eastway Drive (former BP), and
4320 The Plaza (former Eastway Texaco) as RECs in connection with the Site.

September 2014 Phase I ESA
In September 2014, Solutech Environmental Consultants (Solutech) completed a Phase I ESA
for the northern Site parcel. Results of the Phase I ESA identified the following RECs in
connection with the Site:

 Results of the Phase I ESA identified the potential for impact associated with historical
on-Site auto repair operations (former Eastway Auto Repair) as an REC.

 Results of the Phase I ESA identified the documented release associated with the former
60 Minute Cleaners / Joe Harris Dry Cleaners (4447 The Plaza) facility as a REC.

2018 Phase I ESAs
In March 2018 and April 2018, Resource Environmental Consulting, Inc. completed Phase I
ESAs for Site. Results of the Phase I ESAs identified the following REC in connection with the
Site:

 Results of the Phase I ESA identified the documented release associated with the former
60 Minute Cleaners / Joe Harris Dry Cleaners (4447 The Plaza) facility as a REC for the
southern Site parcel.

The Site was entered into the DEQ Brownfields Program to address potential environmental
concerns associated with historical on-Site and off-Site operations (eligibility letter issued
November 6, 2018). A kick-off/data gap meeting with the PD and DEQ Brownfields personnel
was held on August 24, 2022, to discuss prior Site history, proposed redevelopment plans, data
gaps, and the proposed schedule for completing the Brownfields Agreement. H&H has prepared
this Work Plan to conduct Brownfields assessment activities at the Site to address data gaps and
DEQ Brownfields requests for additional assessment.

The purpose of the Brownfields assessment activities described herein is to further evaluate the
potential for impacts at the Site and assist with the management of Site media during proposed
redevelopment of the Site. The Brownfields assessment activities discussed in the following

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
sections focus on collection of soil, groundwater, and soil gas samples. In addition to the
sampling activities, a receptor survey will be conducted to obtain information associated with
land use, potable water supply, and potential sensitive receptors in the area surrounding the Site.

A summary of the proposed Brownfields assessment activities is provided in the following
sections.

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
2.0 Brownfields Assessment Activities

The Brownfields assessment activities will be conducted in general accordance with the DEQ
IHSB Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines) dated
September 2022, the DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance
(VI Guidance) dated March 2018, most recent versions of the U.S. Environmental Protection
Agency (EPA) Region IV Laboratory Services and Applies Science Division (LSASD) Field
Branches Quality System and Technical Procedures guidance, and the DEQ Brownfields
Program Environmental Site Assessment Work Plan Minimum Requirements Checklist dated
November 2018.

Prior to conducting the proposed assessment 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. Additionally, soil boring locations will be hand
cleared to approximately 5 feet below ground surface (ft bgs) prior to use of mechanical drilling
equipment to further screen the boring locations for the presence of subsurface utilities.

In accordance with Mecklenburg County rules, H&H will also obtain a Subsurface Investigation
Permit (SIP) from Mecklenburg County prior to temporary monitoring well installation and
sampling. After completion of the activities, H&H will update the SIP on the Mecklenburg
County Well Information database with temporary monitoring well abandonment records
provided by a North Carolina licensed driller.

2.1 Receptor Survey

H&H will perform a receptor survey in accordance with DEQ Brownfields Program protocols.
The receptor survey 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 boundary. In addition, H&H will review the online
8

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-019 eastway
plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
Mecklenburg County Well Information System for potential wells in the area and, if warranted,
contact utility companies for information concerning underground utilities in the immediate area
of the Site. The receptor survey will be completed using the most current version of the
Brownfields Property Receptor Survey template form. A copy of the Brownfields Property
Receptor Survey template form is provided in Appendix B.

2.2 Soil Sampling Activities

H&H will conduct soil sampling as part of the Brownfields assessment activities. The purpose
of the soil sampling is to evaluate for potential impacts in areas of potential environmental
concern and to evaluate potential impacts in areas that may be disturbed during planned
redevelopment and grading activities.

Soil borings will be advanced adjacent to the former auto repair tenant space in the northeastern
portion of the Site, adjacent to Site buildings, and from general locations in the northern, eastern,
and southern portions of the Site. To evaluate soil conditions in these areas, H&H will collect
seven (7) soil samples from seven (7) soil borings advanced in the vicinity of Site buildings, and
in the northern, eastern, and southern portions of the Site. Locations of the proposed soil borings
are shown in Figure 3, and a tabular summary of proposed samples depths, objectives, and
laboratory analyses are summarized in Table 1.

Note that soil samples are not proposed in the areas of the former 60 Minutes dry cleaner facility,
or the areas adjacent to the former Dutch Cleaners facility located adjacent to the southwestern
Site boundary, since there is existing soil sampling data from the DSCA Program assessment
activities. Soil assessment will be completed in these portions of the Site as needed based on
review of the grading plan and cut-fill analysis once prepared by the project civil engineers.

Former Auto Repair Tenant Space and General Site Characterization
H&H will team with a qualified drilling contractor to advance five soil borings (BF-SB-01
through BF-SB-05) at the Site utilizing a decontaminated stainless steel hand auger and track-
mounted drill rig capable of using direct push technology (DPT) drilling techniques. Continuous

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
soil samples will be collected from each boring and logged for lithological description and field
screened for indication of potential impacts by observation for obvious staining, unusual odors,
and the presence of volatile organic vapors using a calibrated photoionization detector (PID).
Soil samples will be collected from the depth interval that exhibits the highest potential for
impact or as described below.

 Two soil borings (BF-SB-01 and BF-SB-02) will be advanced adjacent to the former auto
repair tenant space located in the northeastern portion of the Site. The borings will be
advanced to approximately 10 ft bgs and a soil sample will be collected from the depth
interval with the highest potential for impacts based on field screening results. If no
obvious evidence of impact is observed during field screening, a sample will be collected
from shallow soil (i.e., no greater than 2 ft bgs).

 Two soil borings (BF-SB-03 and BF-SB-04) will be advanced adjacent to the existing
multi-tenant commercial building located in the central portion of the Site. The borings
will be advanced to approximately 10 ft bgs and a soil sample will be collected from the
depth interval with the highest potential for impacts based on field screening results. If
no obvious evidence of impact is observed during field screening, a sample will be
collected from shallow soil (i.e., no greater than 2 ft bgs).

 One soil boring (BF-SB-05) will be advanced in the southern portion of the Site. The
boring will be advanced to approximately 10 ft bgs and a soil sample will be collected
from the depth interval with the highest potential for impacts based on field screening
results. If no obvious evidence of impact is observed during field screening, a sample
will be collected from shallow soil (i.e., no greater than 2 ft bgs).

 Two background soil samples (BG-1 and BG-2) will be collected at the Site to evaluate
background levels of naturally occurring metals. The soil samples will be collected from
the northern and eastern portions of the Site in wooded areas that appear to be
undisturbed by historical uses. The soil borings will be advanced to 5 ft bgs and soil
samples will be collected from the depth interval with the highest potential for impacts

based on field screening results. If no obvious evidence of impact is observed during
field screening, a sample will be collected from shallow soil (i.e., no greater than 2 ft
bgs).

The soil samples selected for laboratory analysis 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. The samples will be delivered to a North
Carolina certified laboratory under standard chain of custody protocols for laboratory analysis.
Soil samples will be analyzed for VOCs by EPA Method 8260, semi-VOCs (SVOCs) by EPA
Method 8270, Resource Conservation and Recovery Act (RCRA) metals plus hexavalent
chromium by EPA Methods 6020/7471/7199.

Following sampling activities, the soil borings will either be properly abandoned and the surfaces
will be repaired similar to pre-drilling conditions, or will be converted into temporary monitoring
wells or soil gas sampling points as described below. Additionally, the soil sample locations will
be estimated using a hand-held global positioning system (GPS) unit.

2.3 Groundwater Sampling Activities

H&H will collect samples from two (2) existing monitoring wells (MW-A and MW-4) to
evaluate current subsurface conditions for potential impacts associated with historical on-Site
dry-cleaning operations in the southern and southwestern portions of the Site. In addition, H&H
will contract a qualified drilling contractor to advance borings for installation of five (5)
temporary groundwater monitoring wells at the Site. The purpose of the temporary groundwater
monitoring wells will be to evaluate current groundwater conditions in areas where previous
assessment activities have not been completed. The locations of the existing monitoring wells
and proposed temporary monitoring wells are shown in Figure 3, and are described further
below:

 One temporary monitoring well (BF-TMW-1) will be installed in the western and
upgradient portion of the Site;
11

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
 One temporary monitoring well (BF-TMW-2) will be installed in the central portion of
the Site and downgradient of former on-Site auto repair operations;
 One temporary monitoring well (BF-TMW-3) will be installed in the northern and
upgradient portion of the Site;
 One temporary monitoring well (BF-TWM-4) will be installed in the eastern and
topographically downgradient portion of the Site; and
 One temporary monitoring well (BF-TMW-5) will be installed in the southeastern and
topographically downgradient portion of the Site.

The temporary groundwater monitoring well borings will be advanced with a track-mounted drill
rig capable of utilizing hollow-stem auger drilling techniques. During drilling, soil cuttings will
be collected and logged for lithologic description and field screened for the presence of obvious
staining, unusual odors, and elevated volatile organic vapors using a calibrated PID. Should
obvious evidence of impacts be observed based on field screening results, a soil sample will be
collected for laboratory analysis using the methodologies described in Section 2.2 above.

The temporary groundwater monitoring wells will be constructed of 1 or 2-inch diameter PVC
with a 10 to 15 ft section of well screen set to bracket the water table and 1 or 2-inch diameter
PVC well casing to the ground surface. A sand filter pack will be placed from the bottom of the
borings to approximately 2 ft above the top of the well screens. The temporary wells will be
completed by placing a minimum of an approximately 2 ft thick hydrated bentonite seal above
the sand filter pack.

Once the temporary monitoring wells are installed, the wells will be allowed to equilibrate to
static conditions, and a decontaminated electronic water level indicator will be used to measure
the depth to the water table relative to the ground surface and tops of well casings in each well.
The wells will then be developed by removing a minimum of 3 to 5 volumes and until field
parameters have stabilized (pH± 0.1 Standard Units [SU] and conductivity varies no more than
5%). The ground surface and top of well casing elevations will be surveyed by H&H relative to
a known elevation at the Site (e.g., existing DSCA monitoring well) to obtain the groundwater
flow direction.

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
After development, groundwater samples will be collected utilizing low flow/low stress purging
techniques using a peristaltic pump or bladder pump and dedicated polyethylene tubing. The
intake point of the pump tubing will be placed in the approximate 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 calibrated water quality meters to collect measurements of pH,
temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity
at three to five-minute intervals during the purging process. Purging will be considered complete
when the field parameters stabilize (pH ± 0.1 SU, conductivity varies no more than 5%, and
turbidity is less than 10 Nephelometric Turbidity Units [NTUs]).

Once groundwater parameters stabilize, groundwater samples for VOC analysis will be collected
directly into laboratory supplied sample containers using the “soda straw” method to minimize
the potential for volatile compound loss through the peristaltic pump head. Samples collected
for the remaining analyses will be collected directly into laboratory supplied sample containers
from the dedicated sample tubing discharge. The sample containers will be labeled with the
sample identification, date, time, and requested analysis, and placed in a laboratory supplied
cooler with ice. The groundwater samples will be delivered to a North Carolina certified
laboratory under standard chain of custody protocols for analyses of VOCs by EPA Method
8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Method 6020/7470.

The groundwater sample locations will be estimated using a hand-held GPS unit. Following
sampling activities, the temporary monitoring wells will be properly abandoned by a licensed
well driller and the surfaces will be repaired similar to pre-drilling conditions.

2.4 Soil Gas Sampling Activities

To evaluate the potential for structural vapor intrusion into the proposed buildings, H&H will
install and sample twenty-three (23) temporary exterior soil gas monitoring points and four (4)
temporary sub-slab soil gas sampling points within existing Site buildings. The proposed
exterior and sub-slab soil gas sampling point locations are shown in Figure 3, and the sampling
activities are described below.
13

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc

Exterior Soil Gas Sample Points
Twenty-three (23) temporary exterior soil gas monitoring points (BF-SG-1 through BF-SG-23)
will be installed within the footprint of the proposed apartment, for-rent townhome, commercial,
and amenities buildings (Figure 3).

The soil gas monitoring points will be installed at depths greater than 5 ft bgs. Based on the
anticipated depth to water at the Site (approximately 10 ft bgs to 15 ft bgs) it is anticipated that
the soil gas points will be installed to a depth of approximately 7 ft bgs to 9 ft bgs. The soil gas
point borings will be advanced utilizing a track-mounted drill rig capable of using direct push
technology (DPT) drilling techniques to advance an approximate 6-inch stainless steel vapor
implant screen attached to a length of Teflon® tubing. Following advancement, the DPT tooling
will be retracted and the annular space around the vapor screen will be filled with filter sand to
approximately 6-inches above the vapor screen. Following installation of the sand, hydrated
bentonite will be installed in the boring from the top of the sand to near the ground surface.

Sub-Slab Soil Gas Sample Points
H&H proposes to install four (4) sub-slab soil gas sample points (BF-SSV-1 through BF-SSV-4)
for collection of soil gas samples beneath the existing Site buildings. With the exception of one
sub-slab soil gas sample which is located within a proposed courtyard area, the sub-slab soil gas
samples are proposed in locations that will be within the footprint of proposed residential
buildings. The results of the sub-slab soil gas samples will be used to evaluate current conditions
beneath existing Site buildings and serve as baseline sub-slab conditions for proposed buildings.
The proposed sub-slab soil gas sample locations are shown on Figure 3.

The sampling points will be installed using a rotary hammer drill and 1½-inch diameter drill bit
to advance a pilot hole into the concrete slab to a depth of approximately 1¾ inches below the
surface. A drill guide will then be placed in the pilot hole, and a 5/8-inch diameter drill bit will
be utilized to advance the drill bit through the concrete slab and into the underlying soil.
Following concrete borehole advancement, loose concrete cuttings will be removed from each
boring, and a Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone
14

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-019 eastway
plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
sleeve) will be seated in the borehole using an installation/extraction tool and hammer to form an
airtight seal.

Exterior and Sub-Slab Soil Gas Sampling
The sub-slab and exterior soil gas samples will be collected utilizing laboratory supplied batch
certified Summa® canisters (1 or 3-liter canisters depending on laboratory availability) connected
to an air-flow regulator calibrated by the laboratory to collect the soil gas sample at a rate of
approximately 100 mL/min. Prior to collection of the soil gas samples, a “shut-in” test will be
conducted on the sampling train and helium leak checks will be conducted at each soil gas
sampling point. The purpose of the shut-in test and helium leak check is to ensure short
circuiting with ambient air does not occur during sampling. A description of the shut-in test and
helium leak testing procedures is provided below.

The shut-in test will be conducted by connecting the flow regulator with the vacuum gauge to the
Summa® canister and sealing the flow regulator with the laboratory provided brass cap. Once
the sampling train is “closed”, the sample valve on the Summa® canister will be opened and the
reading on the vacuum gauge will be recorded. The Summa® canister sample valve will then be
closed and the vacuum gauge will be observed to ensure no vacuum loss occurs. If the vacuum
reading remains the same, the shut-in test will be considered successful. If vacuum loss occurs,
the flow regulator and/or brass cap will be reseated, and the shut-in test will be repeated until the
vacuum reading remains stable.

Following the shut-in test, the Summa® canister will be connected to the sample point via
Teflon® sample tubing using a brass nut and ferrule assembly to create an airtight seal and the
leak check will be performed. The leak check will be performed by constructing a shroud over
the entire sampling train and flooding the shroud with helium gas. A calibrated helium gas
detector will be utilized to measure helium concentrations within the shroud. Once helium
concentrations stabilize within the shroud, the sample tubing will be purged outside of the shroud
using a syringe and a three-way valve to collect purged soil gas into a Tedlar® bag. The purged
soil gas will then be analyzed using the helium gas detector to ensure that helium concentrations
in the soil gas point are less than 10% of the helium concentrations measured within the shroud.

plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc

Following successful leak checks, the soil gas samples will be collected. 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 of approximately 5 inches of mercury or
more will be maintained within the canisters at the conclusion of the sampling event in
accordance with DEQ DWM guidance. Following sample collection, the Summa® canisters will
be shipped to a laboratory under standard chain-of-custody protocols for analysis of VOCs by
EPA Method TO-15. The laboratory will be requested to use reporting limits that are below
DEQ Residential Vapor Intrusion SGSLs.
After sampling is complete, the sample locations will be estimated using a hand-held GPS unit or
by measuring from known benchmarks within the buildings (e.g., doors, windows, etc.), and the
sample locations will be abandoned with surfaces repaired similar to pre-drilling conditions.

2.5 Quality Assurance – Quality Control

Non-dedicated equipment and tools will be decontaminated prior to use at each boring or
sampling location or following exposure to soil or groundwater. The following samples will be
collected for quality assurance/quality control (QA/QC) purposes:

 One duplicate soil and groundwater sample will be collected and analyzed for the same
parameters as the parent samples.
 One trip blank will accompany the groundwater samples during the field activities as well
as during sample shipment and will be analyzed for VOCs by EPA Method 8260.
 One duplicate soil gas sample will be collected for every 20 samples collected for a total
of two (2) duplicate soil gas samples. Parent and duplicate soil gas samples will be
collected using a laboratory supplied “t-fitting” which allows for two soil gas samples to
be collected from one soil gas monitoring point simultaneously. The duplicate soil gas
sample will be submitted for analysis of VOCs by EPA Method TO-15.

Laboratory 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
16

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-019 eastway
plaza/brownfields assessment/work plan/22044 - brownfields assessment work plan_eastway plaza.doc
conducted in accordance with the method protocols and will include regular equipment
maintenance, equipment calibrations, and adherence to specific sample custody and data
management procedures. Samples will be analyzed in conjunction with appropriate blanks,
laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking
standards in accordance with approved methodologies to monitor both instrument and analyst
performance. Laboratory reporting limits for each analyte will be at or below appropriate
screening criteria, where possible. Additionally, H&H will request that the laboratory include
estimated concentrations for compounds that are detected at levels above the laboratory method
detection limit, but below the laboratory reporting limit (J flags).

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.
Laboratory QA data consistent with Level II documentation will be provided for this project.
A copy of the completed chain of custody record and shipping receipt will be appended to the
corresponding laboratory analytical report included with the final report.

2.6 Investigation Derived Waste

Investigation derived waste (IDW) generated during the proposed assessment activities will be
managed in general accordance with DEQ IHSB Guidelines. IDW generated during the
assessment activities will be containerized in labeled 55-gallon drums and staged on-Site
pending analytical results of a composite IDW sample. Based on laboratory analytical results of
IDW samples, the drums will be transported off-Site to a suitable facility for disposal.

3.0 Reporting

Following completion of the assessment activities and receipt of the analytical data, H&H will
document our findings in a Brownfields Assessment Report. The report will include a
description of the sampling activities; a figure depicting sample locations; a figure showing the
potentiometric surface, boring logs for the soil borings, temporary well borings, and soil gas
monitoring points; temporary well and soil gas monitoring point construction logs; groundwater
sampling logs; laboratory analytical data; a discussion of the data in comparison to regulatory
screening levels; and conclusions and recommendations concerning our activities. H&H will
also use the most recent version of the DEQ risk calculator to further evaluate potential risks
based on the data, if warranted. The Brownfields Assessment Report will include the firm
PE/PG license numbers and individual PE/PG seal and signature.

Chronology of Events
10/26/1994 Environmental Site Assessment (ESA) performed by Industrial Brokerage Services on behalf of the property owner.
PCE impacted soil was discovered at the site during ESA activities.
1995
Building onsite was demolished. Letter dated 8/17/1995 sent to Hazardous Waste Section, documented excavation of
approximately 30 tons of PCE impacted soils. Confirmatory soil samples indicated that soils below the excavation area
contained PCE concentrations less than 5 ppb.
8/28/2001
ESA for the property across the site (Former 60 Minute Cleaners) was performed by Geosciences Group, Inc. During the
ESA, the former 60 Minute Cleaners was identified as a potential contaminated site. Four monitoring wells were
installed on the property across from the former 60 Minute Cleaners and groundwater samples were collected from each
well. Analytical results indicated that dissolved concentrations of PCE were present beneath the site above the NC 2L
standard.
12/19/2001 Former 60 Minute Cleaners was certified into DSCA Program.
12/11/2002 Prioritization Assessment Agreement finalized by petitioner and NCDEQ.
8/30/2005
Prioritization Assessment submitted by Geosciences Group to NCDEQ. Analytical results indicated that PCE impacted
soil and groundwater remained at the site. The horizontal and vertical extent of soil and groundwater impacts were not
delineated to the Tier I Standards. It appeared that the PCE plume migrated off site.
