1.0 INTRODUCTION
The subject property (Figure 1) is identified by Mecklenburg County GIS as Parcel Identification Numbers
(PINs) 12307312 (1601 South Boulevard), 12307313 (1605 South Boulevard), 12307314 (1609 South
Boulevard), and 12307308 (1612 Cleveland Avenue), and are owned by South End I, LLC, and PIN
12307315 (1617 South Boulevard) owned by Maria P. Kyritsis and Joana P. Pandrinopoulos.
The approximate 0.611-acre portion of the subject property located at 1601 to 1609 South Boulevard and
1612 Cleveland Avenue consists of one building and paved parking areas. The approximate 3,726-square
foot single-story building was constructed in 1940, is located at 1601 South Boulevard, and previously
consisted of two restaurants, Sandwich Max and Beijing Chinese. This portion of the assessment site
received eligibility from the Brownfields Redevelopment Section (BRS) on December 16, 2022, and was
assigned the name McCorkles Cleaners and Brownfields Project No. 26076-22-060.
ECS previously conducted a Phase I Environmental Site Assessment (Phase I ESA) for this portion of the
subject site (ECS Project No. 49:15946 dated January 14, 2022). During this Phase I ESA, the following
recognized environmental conditions (RECs) were identified:
• ECS considered the potential for the former onsite drycleaners (in approximately 1944) to impact
the subject property to be a REC for the subject property.
• Based on the distance from the subject property and documented groundwater contamination,
ECS considered the potential for the offsite CC Dickson facility to impact the subject property to
be a REC.
• Based on the documented groundwater contamination above the North Carolina Department of
Environmental Quality (NCDEQ) Standards and distance from the subject property, ECS
considered the facility at 1620 South Boulevard to be a REC for the subject property.
• Based on the groundwater and soil gas detections above the applicable levels and distance to the
subject property, ECS considered the potential for the Dilworth Auto Service facility to impact the
subject property to be a REC.
• ECS considered the potential for the former adjacent gas stations and auto repair facility to the
north, northwest, and west to impact the subject property to be a REC.
• ECS considered the potential for the former adjoining/adjacent drycleaners to the northeast and
northwest to impact the subject property to be a REC.
• Based on proximity, length of operation, and potential for an undocumented release to migrate
and impact the subject property, ECS considered the Brakes 4 Less auto repair facility to represent
a REC for the subject property.
The approximate 0.235-acre subject property located at 1617 South Boulevard is developed with a 405-
square foot vacant office building that was reportedly originally constructed in 1939. A metal awning is
attached to the rear of the building. The southeastern half of the subject property is currently leased to
Graystar for parking and a construction trailer. On March 8, 2023, South End I, LLC submitted an amended
Brownfields Application to add this parcel to the McCorkles Cleaners Brownfields Project. ECS previously
conducted a Phase I ESA for this portion of the subject site (ECS Project No. 49:18794-A dated February 3,
2023) also. During this Phase I ESA, the following RECs were identified:

• ECS considered the potential for a former adjacent drycleaner approximately 50 feet northeast
(in approximately 1944) to impact the subject property to be a REC for the subject property.
• ECS considered the potential for former adjacent gas stations and an auto repair facility to the
north, northwest, and west to impact the subject property to be a REC.
• ECS considered the potential for the former adjoining/adjacent drycleaners to the northeast and
northwest to impact the subject property to be a REC.
In an effort to determine if the subject property has been adversely affected by the identified RECs, ECS
was requested to conduct an Environmental Assessment at the site. The results of these assessment
activities were summarized in ECS’s Environmental Assessment Services Report, dated April 18, 2023 (ECS
Project Nos.: 49:15946-B and 49:15946-C).
As part of the assessment activities, ECS collected two exterior soil gas samples, nine soil samples, and
four groundwater samples. The previous sample locations are shown on Figure 2. Review of the
laboratory analytical results for the exterior soil gas samples indicated 1,3-butadiene in the SG-1 and SG-
2 samples and tetrachloroethene (also known as perchloroethene or PCE) and trichloroethene (TCE) in
the SG-2 sample at concentrations greater than their respective NCDEQ Residential Vapor Intrusion
Screening Levels (VISLs).
Methylene chloride in each of the soil samples collected; PCE in soil samples SB-7, SB-8, and SB-9; and
benzo(a)pyrene in soil samples SB-1 and SB-8 were detected at concentrations greater than their
respective Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs). The concentrations of
benzo(a)pyrene detected in soil samples SB-1 and SB-8 were also greater than its Residential PSRG.
Arsenic in soil samples SB-1 and SB-4, lead in soil sample SB-1, and mercury in soil sample SB-5 were
detected at concentrations greater than their respective Protection of Groundwater PSRGs. In addition,
arsenic in each of the soil samples collected; hexavalent chromium in soil samples SB-1, SB-2, SB-8, and
SB-9; lead in soil samples SB-1 and SB-4; and mercury in soil sample SB-5 were detected at concentrations
greater than their respective Residential PSRGs.
PCE in the TW-1, TW-3, and TW-4 groundwater samples; TCE in the TW-1 groundwater sample; and total
and dissolved total chromium in the TW-2 groundwater sample were detected at concentrations greater
than their respective North Carolina 2L Groundwater Quality Standards (NC2LGWQS). The concentrations
of PCE and TCE detected in the TW-1 groundwater sample were greater than their respective Residential
Groundwater VISL.
Based upon the results of the SG-1 and SG-2 exterior soil gas samples and the TW-1 groundwater sample,
ECS input the detected concentrations for each sample into the NCDEQ Risk Calculator to evaluate the
risk of VOCs in vapor migrating into indoor air through vapor intrusion. The results of the NCDEQ Risk
Calculator indicated the concentrations detected in the SG-1 exterior soil gas sample did not exceed the
Hazard Index for the Residential risk classification; however, the concentrations detected in the SG-2
exterior soil gas sample did exceed the Hazard Index for the Residential Risk Classification. The results of
the NCDEQ Risk Calculator indicated the concentrations detected in the TW-1 groundwater sample did
exceed the Hazard Index for the Residential risk classification.
On May 24, 2023, a Brownfields Kickoff meeting was conducted with Sterling Bay Companies, their

environmental attorney, ECS, and Ms. Carolyn Minnich, the assigned BF Project Manager (BPM). During
the course of the kickoff meeting, the actual location of the former McCorkles Cleaners was unable to be
determined; therefore, Ms. Minnich suggested that the name of the Brownfields site be changed to 1601
South Boulevard but the Brownfields Project number remained unchanged. Also discussed during the
kickoff meeting were the site history, environmental information currently known for the site and
surrounding area, sampling and analytical results previously collected, as well as the planned future
development. As a results of the meeting, additional sampling was requested in order to further assess
the site and to address potential data gaps in the data. Based on the results of that meeting, ECS has
prepared this work plan to address the below data gaps identified by the BPM:
• Additional soil assessment (predominately in areas of proposed deeper soil disturbance);
• Sub-slab soil vapor intrusion evaluation in two onsite buildings that are now vacant; and
• Completion of a Brownfields Receptor Survey.
Currently the site is not regulated by another NCDEQ department; therefore, the data is to be collected
solely for the NCDEQ BRS.
2.0 SCOPE OF WORK
The scope of work described by media below generally includes 5 soil borings with up to three samples
per boring, and three sub-slab soil gas samples. The drilling and sampling activities will be conducted in
general accordance with the USEPA, Region 4: Science and Ecosystem Support Division (SESD) – Standard
Operating Procedures (SOPs); USEPA, Region 4 – Laboratory Services & Applied Science Division (LSASD)
– SOPs; and the NCDEQ Vapor Intrusion guidelines.
2.1 Soil Boring Advancement
• ECS will observe the advancement of seven borings at the site in order to assess site soils. Soil samples
will be collected of at varying depths, generally one sample for every 5 feet in depth, depending upon
the area in which they are installed as discussed below:
Two soil borings (E-1 and E-2) will be advanced to depths of approximately 15 feet below ground
surface (bgs), or until groundwater is encountered in the area of the proposed deeper elevator
shafts.
Two soil borings (P-1 and P-2) will be advanced to depths of 15 feet bgs in the areas of the
proposed building footprint where deeper foundations are expected that will require excavation
of the soils.
One soil boring (P-3) will be advanced to a depth of 15 feet bgs in an area that previously was not
sampled.
Two soil borings (DP-1 and DP-2) will be advanced to depths of five feet bgs in the area planned
to be developed as a dog park.
• The borings will be conducted utilizing a direct push technology (DPT) type drilling rig. The proposed
boring and sample the locations are shown on Figure 3.

2.2 Sub-Slab Soil Gas Probe Installation
• ECS anticipates that three sub-slab soil gas samples will be collected in the two existing site buildings
using a hammer drill to penetrate through the concrete slab. Two of the locations are anticipated to
be within building located at 1601 South Boulevard and the remaining sample location is anticipated
to be in the other remaining site building at 1617 South Boulevard, as indicated on Figure 3. Once the
concrete slab has been penetrated, a new VaporPin® with a new silicon sleeve will be inserted in the
concrete slab in general conformance with manufacturer’s recommendations (Vapor Pin Enterprises,
Inc.). The VaporPin® setup will be allowed to equilibrate for at least 20 minutes prior to leak testing.
• A sample train consisting of non-reactive tubing and microvalves will be connected to a VaporPin®
and to a Summa canister. A shut-in test will be performed on the sample train and Summa canister
to confirm that leaks are not present in the sampling train. A microvalve at the connection between
the sampling train and the VaporPin® will be closed, and a vacuum will be applied to the sampling
train using a disposable syringe. The vacuum gauge on the Summa canister will be monitored for
declining vacuum indicative of a leak. If a leak is indicated by a shut-in test, steps will be taken achieve
better connections in the sample train.
• Prior to sample collection, the seal of the VaporPin® will be leak tested using helium gas, a shroud,
and a helium detector as recommended in NCDEQ Division of Waste Management (DWM) Vapor
Intrusion Guidance. A shroud will be placed and sealed over the VaporPin®, sample train, and Summa
Canister (further discussed below). The shroud will be flooded with laboratory grade helium via the
hose placed through the shroud wall. The concentration of helium inside the shroud will be measured
with a helium detector (Model MGD-2002 Multi-Gas Leak detector or similar device). The sample
train and interstitial space of each VaporPin® will be purged of at least 3 volumes via tubing routed
through the wall of the shroud to a syringe. The flow rate during purging will be at a rate of 200
milliliters per minute or less. Following purging, a soil gas sample will be withdrawn and extracted
soil gas will be directed to a Tedlar bag and monitored with a helium detector. If the concentration
measured is less than 10 percent of the helium concentration inside the shroud, the seal on the
VaporPin® and sampling train will be considered to be tight and not leaking. If a leak is noted, ECS will
make adjustments and repeat the testing process.
• ECS will obtain a one-liter Summa canister from a commercial laboratory that follows NELAC standards
and participates in the NELAP. The canister will be pre-cleaned and pre-evacuated so that it is under
negative (i.e., under vacuum). The canister will be batch certified by the laboratory. The Summa
canister will be outfitted with a flow regulator set to 200 milliliters per minute and a vacuum gauge.
2.3 Deviation from Approved Plan
This work plan is intended to be dynamic and to be adapted to specific and actual site conditions.
Accordingly, should such conditions warrant a change either by addition, deletion or modification of a
procedure, such may be accomplished with agreement between the Prospective Developers’
representative and ECS after consultation with, and subject to approval by the NCDEQ BRS. Such changes
will comply with applicable local, State, and Federal rules and regulations. A written amendment shall be
prepared and submitted to NCDEQ BRS for approval (the use of e-mail correspondence shall suffice for
approval) prior to implementation. The amendment and approval will be included in the report for final
documentation. Amendments must have the approval of the NCDEQ BRS prior to implementation.

3.0 SAMPLING METHODOLOGY
The sampling activities will be conducted in general accordance with, SESD and LSASD SOPs, and NCDEQ
Vapor Intrusion guidelines.
3.1 Soil Sampling
• ECS will provide a project professional to collect soils continuously from the ground surface to the
termination depth of the soil borings. The soils will be collected over the length of the boring in
approximately 5-foot intervals and screened in the field by placing a portion into a resealable plastic
bag and measuring for volatile organic vapors using a photoionization detector (PID) after allowing to
set for approximately 15 minutes. The remaining soils from each approximate 5-foot interval (i.e., 0-
5 ft bgs; 5-10 ft bgs; and 10-15 ft bgs, as applicable) will be placed directly into the laboratory sample
containers. The soil samples to be submitted to the laboratory for analysis will be collected from
separate soils than that which was allowed to volatilize for the collection of the PID readings.
• The soil samples collected from the borings will be submitted to a North Carolina certified laboratory
under standard Chain-of-Custody (COC) protocols, in a cooler containing ice to maintain the samples
at less than 6 degrees Celsius (°C). The samples will be either hand delivered or shipped by standard
courier to the laboratory either at the end of each sample day or the following day.
• The soil samples will be submitted for laboratory analysis of volatile organic compounds (VOCs) by
EPA Method 8260; semi-volatile organic compounds (SVOCs) by EPA Method 8270 SIM; total RCRA
metals by Methods 6020/7470; and hexavalent chromium (Cr VI) by Method 7199. The laboratory will
be instructed to report to the lowest possible concentration and estimated concentrations (i.e., “J
flags”) below the laboratory reporting limit (RL) and the laboratory method detection limit (MDL).
• The results of the soil analyses will be compared to the NCDEQ, DMW, residential use Preliminary Soil
Remedial Goals (PSRGs).
• At completion of sampling activities, the soil borings will be backfilled with the soil cuttings generated
during the boring activities and capped with asphalt, soil, or concrete, as appropriate. A summary of
the proposed samples and analyses are provided in Table 1.
3.2 Sub-Slab Soil Gas and Sampling
• ECS will check and note the vacuum on the Summa Canisters before initiating the sampling procedure.
If the initial vacuum prior to sample collection is less than 10 percent of the vacuum documented by
the laboratory at shipment, the Summa canister will not be used. ECS will open the valve on each
Summa cannister to initiate sampling. ECS will terminate the sampling procedure at each sampling
point while a vacuum of at least 5 inches of mercury is still present in the canister. ECS will note the
vacuum for the canister at the end of the sampling procedure. In addition, the vacuum will not be
allowed to reach zero inches of mercury.
• The Summa canister will be submitted to a NELAP certified laboratory under COC protocols for
analyses of VOCs by EPA Method TO-15. ECS will request that the laboratory analyze vapor samples
for the most current and applicable standards from NELAP. The laboratory will be instructed to use
reporting limits below the appliable NCDEQ screening levels and to report the vacuum measurement
for each sample canister at receipt by the laboratory.
• The results of the laboratory analysis will be compared to the NCDEQ, DWM residential VISLs.

• Following completion of sub-slab soil gas sampling activities, the sub-slab soil gas sampling points will
be abandoned by removing the vapor pins. Since the buildings are vacant and are planned to be
demolished for the proposed redevelopment, the borings will not be capped with concrete. A
summary of the proposed sample and analysis are provided in Table 1.
4.0 LABORATORY ANALYSES
The soil samples will be submitted to a North Carolina certified laboratory for analysis. Since North
Carolina does not certify laboratories for analyses of soil gas/air samples, ECS will request that the
laboratory analyze the sub-slab soil gas samples for the most current and applicable standards from
NELAP. The laboratory will be instructed to use reporting limits below the IHSB PSRGs, and the NCDEQ,
DWM residential VISLs. Additionally, it will be requested that the laboratory MDLs, and J-flags be
included. The laboratory will also be instructed to report the vacuum measurement for each Summa
canister at receipt by the laboratory. Level II QA/QC will be requested to be reported by the laboratory.
4.1 Soil Sample Analyses
As stated above, the soil samples collected from the borings will be submitted for laboratory analysis of
VOCs by EPA Method 8260; SVOCs by EPA Method 8270 SIM; total RCRA Metals by Methods 6020 and
7470; and Cr VI by EPA Method 7199. The samples will be added to laboratory provided, pre-preserved
sample containers.
4.2 Sub-Slab Soil Gas Analyses
As stated above, the sub-slab soil gas samples will be submitted for analyses of VOCs by EPA Method TO-
15.
5.0 QUALITY ASSURANCE/QUALITY CONTROL
Following the collection of the samples described above, the sample containers will be labeled and
shipped to a commercial laboratory using COC protocols to be analyzed.
In addition to the above samples, for Level II QA/QC purposes duplicate soil and sub-slab soil gas samples
will be collected for laboratory analysis per day of sampling of each media. As such it is estimated that
one duplicate soil sample will be collected, and one duplicate sub-slab soil gas sample will be collected.
The duplicate soil samples will be submitted for the same analyses as the record sample they are
associated with. The duplicate sub-slab soil gas sample will be collected in conjunction with the respective
record sample via a “tee” connection in the tubing. Duplicate samples will be submitted to the laboratory
without identification as to their respective record samples.
Also, one equipment blank sample will be collected during soil sampling activities by pouring laboratory
provided distilled water through a DPT soil sampling sleeve (prior to sample collection) and collecting the
water into laboratory provided, pre-preserved sample containers. The equipment blank will be submitted
for laboratory analysis of VOCs, SVOCs, total RCRA metals, and Cr VI by the same methods as the record
samples. One trip blank sample per cooler will accompany the samples from laboratory to the field, and

back to the laboratory and will be analyzed for VOCs.
6.0 RECEPTOR SURVEY
A Brownfields Property receptor survey will be completed, summarized in the report and included as an
attachment within the report. The Brownfields Property receptor survey includes descriptions of the
property and building characteristics, surrounding property land use, nearby utilities, water supplies,
surface water, and wetlands. A blank copy of the NCDEQ Brownfields Property Receptor Survey/Checklist
is included Appendix A.
7.0 INVESTIGATIVE DERIVED WASTE
Investigative derived waste (IDW) generated from the soil borings (i.e., soil cuttings) will be thinly spread
onsite in the vicinity of the boring location to the extent possible, unless impacted soil is apparent based
on field observations (i.e., visual and/or olfactory senses or elevated PID readings). If soil cuttings appear
to be impacted or sufficient space to thinly spread the cuttings is not available, the soil cuttings will be
containerized. If soil cuttings are containerized, additional waste characterization will be conducted based
on the requirements of the disposal facility.
8.0 REPORTING
ECS will prepare a written report documenting the field activities, sampling procedures, sample locations,
laboratory procedures and analytical results discussion, and conclusions for submission to the NCDEQ BRS.
The report will include a sample location figure, boring logs, field notes, and data tables. The soil samples
results will be compared to the current NCDEQ Residential PSRGs and the sub-slab soil gas sample results
will be compared to the current NCDEQ, IHSB, Residential VISLs for Sub-slab and Exterior Soil Gas. If
positive detections are noted, the soil and sub-slab soil gas sample results will also be input into the
NCDEQ Risk Calculator to assess if the results exceed applicable risk thresholds. Sample collection logs
for sub-slab soil gas samples will be included in the report and will include helium leak checks results, and
photographs of the sample arrays. The report will be signed and sealed by a North Carolina Professional
Engineer or Licensed Geologist. The report will also include the identification numbers for ECS’s corporate
Professional Engineers and Geologists Licenses.
The Brownfields Property receptor survey will be completed and summarized in the report. The NCDEQ
Brownfields Property Receptor Survey/Checklist will be included as an attachment to the report.
