1.0 PROJECT INFORMATION

The Brownfields Property is an approximately 12-acres of land located at the southwest corner of Pecan
Avenue and Central Avenue in Charlotte, Mecklenburg County, North Carolina. According to the
Mecklenburg Property Ownership and Land Records Site (POLARIS), the Brownfields Property consists of
parcel numbers: 08117722 (4.545 acres); 08117723 (6.320 acres); and 08117724A/08117724B (1.145
acres). A topographic map of the Brownfields Property area is included as Figure 1 and an aerial of the
Brownfields Property area and approximate parcel boundaries is included as Figure 2.

Assessment History

The Brownfields Property was recently purchased by TGACSE Central Square, LLC and at the time of the
purchase, the Brownfields Property was occupied by various commercial businesses and restaurants,
offices, and associated surface parking and drive areas. Previous assessment activities conducted on the
various parcels include the following:

• EDR Radius Map Summary and Limited Historical Search (EDR Summary Report), prepared by
ECS and dated January 3, 2020.
• Phase I Environmental Site Assessment (Phase I ESA), prepared by ECS and dated January 27,
2020.
• Report of Limited Environmental Assessment, prepared by ECS and dated February 19, 2020.
• Standard Operating & Environmental Procedures for Meineke Car Care Center, prepared by ECS
and dated March 30, 2020.

ECS also reviewed:

• Portions of a Report of Phase II Environmental Site Assessment dated November 3, 1999 that
was conducted prior to development of the CVS Pharmacy.
• A letter of No Further Action (NFA) dated May 12, 1999 for an underground storage tank (UST)
closure at the former Sunoco Station located at 1231 Pecan Avenue (current CVS Pharmacy).
• An additional NFA letter dated September 27, 1999 for the risk-based closure of a UST at the
former Sherwin Williams site.

Both NFA letters were sent by the North Carolina Department of Environment and Natural Resources
(NCDENR, currently the North Carolina Department of Environmental Quality or NCDEQ).

Based on the results of the EDR Summary Report and the Phase I ESA, the below Recognized
Environmental Conditions (RECs) were identified, associated with the site:

• Former onsite Cole Manufacturing facility;
• Former onsite gasoline station at southeast portion of the site;
• Former offsite drycleaner facility listed at 1209 Pecan Avenue; and
• Historical and ongoing operations at onsite Meineke Car Care Center.

Although not considered to be RECs of the site due to receiving the above referenced NFA
letters, the following Historical Recognized Environmental Concerns (HRECs) were identified:

• Former onsite 500-gallon UST used by the former Sherwin Williams facility, which was removed
and received the NFA.
• The seven former onsite USTs that were previously removed from the former gasoline station
that were removed and received the NFA (current CVS Pharmacy location).

Also, after the completion of the Phase I ESA, ECS reviewed the information in the portions of the Report
of Phase II Environmental Site Assessment that was conducted for the CVS site prior to its development
as well as the information pertaining to the NFA at the Former Sherwin Williams site. According to
those documents, in addition to the petroleum UST detections that received the NFA, a chlorinated
solvent (tetrachloroethene or PCE) was detected in one soil samples and one groundwater sample (the
exact location(s) are not confirmed). The PCE in the groundwater sample exceeded the NCAC 2L
Groundwater Quality Standard.

Based on these identified RECs and the additional PCE detections, ECS conducted the referenced Limited
Environmental Assessment activities that included the collection of 4 soil samples and 7 groundwater
samples in various areas of the Brownfields Property. The soil samples were submitted for laboratory
analysis of total petroleum hydrocarbons (TPH) gasoline and diesel range organics (GRO/DRO), volatile
organic compounds (VOCs), semi-volatile organic compounds (SVOCs), total RCRA metals, and
hexavalent chromium. Results of soil sampling did not identify VOCs or SVOCs at concentrations above
their respective Preliminary Soil Remedial Goals (PSRGs); however, select metals were detected at
concentrations greater than residential PSRGs in the four samples and also greater than the soil-to-
water PSRG in one of the samples. Additionally, hexavalent chromium was detected in one sample at a
concentration that was greater than the residential PSRG. The groundwater samples were submitted for
laboratory analysis of VOCs, SVOC, and total RCRA metals. Results of the groundwater analysis
identified chromium in two samples and bromodichloromethane in one sample at concentrations
greater than their respective NCAC 2L Groundwater Quality Standards.

2.0 SCOPE OF WORK

Prior to the initiation of the drilling and sampling activities, ECS will contact North Carolina 811 and a
qualified private utility locator to minimize the potential for utility conflicts with the proposed drilling
locations. Additionally, ECS will procure a Mecklenburg County Subsurface Investigation Permit (SIP) for the
assessment activities.

The objective of this work plan is to collect sixteen soil samples (eight composite and eight grab
samples), two groundwater samples, and nine soil gas samples at various locations throughout the
Brownfields Property. Proposed sample locations are depicted on Figure 5 and a summary of proposed
sample locations and analysis is provided in Table 1.

Soil Samples

The soil samples will be collected from depths ranging from 2 to 10 feet below the ground surface (bgs),
dependent upon estimated cut/fill depths within the various proposed redevelopment areas and field
screening results. Composite and grab samples will be collected from each of the eight divided areas
within the proposed redevelopment areas, as indicated on Figure 5. Up to 5 soil borings will be
conducted in each of the eight divided areas and field screened for evidence of impacts by observing for
staining, petroleum or chemical odors, and relative volatile organic vapor readings collected using a
Photoionization Detector (PID). The soil interval / boring indicating the most apparent evidence of
impacts based on field screening from each divided area will be collected as a grab sample and
submitted for laboratory analysis of volatile organic compounds (VOCs). The depth interval from each
boring within the proposed cut depth will be collected, composited and submitted for laboratory
analysis of semi-volatile organic compounds (SVOCs), total RCRA metals, and hexavalent chromium.
The composite samples will represent each of the eight divided areas. The VOC grab soil samples will be
submitted for laboratory analysis by EPA Method 8260. The composited samples will be submitted of
SVOCs by EPA Method 8270, with the total RCRA Metals analyzed by EPA Method 6020, and the
hexavalent chromium samples analyzed by EPA Method 7199.

Groundwater Samples

The two proposed groundwater samples will be collected from new temporary monitoring wells drilled
and constructed in the general west central and southwest central areas of the Brownfields Property, as
indicated on Figure 5. The groundwater samples will be submitted for laboratory analysis of VOCs using
EPA Method 8260 and SVOCs using EPA Method 8270. The groundwater samples will not be analyzed
for RCRA metals in light of prior assessment data.

Soil Gas Samples

The nine proposed soil gas samples will be collected from a depth of 5 feet below the ground surface in
the vicinity of the proposed building planned for potential mixed commercial and multifamily residential

use, as indicated on Figure 5. The samples will be submitted for laboratory analysis of VOCs by EPA
Method TO-15.

Receptor Survey

A 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.

3.0 SAMPLING METHODOLOGY & LABORATORY ANALYSIS

The soil, groundwater, and soil gas sampling will be conducted in general accordance with the North
Carolina Division of Waste Management’s (NCDWM) Inactive Hazardous Site Program’s Guidelines for
Assessment and Cleanup (Revised October 2015) and the NCDMW Vapor Intrusion Guidance (March
2018, Version 2).

Soil Sampling

In accordance with the discussions during the above-referenced kickoff web meeting, ECS is proposing
to collect eight composite and eight grab soil samples from various proposed redevelopment areas of
the Brownfields Property, as indicated on Figure 5. At each of the eight areas, ECS will conduct up to 5
borings using a macro core soil sampler driven by the DPT drilling rig. The depth of each boring will be
dependent upon the estimated “cut” depth for the future development; however, it is estimated that
the borings will not exceed 10 feet in depth below the current ground surface. Should groundwater be
encountered prior to reaching the targeted depth, the boring will cease.

After retrieval of each pre-decontaminated 5-foot macro core soil sampler, the inner clear liner will be
removed, cut open to expose the removed soil, and the soils will be described and logged on a bore log
noting soil colors, type, size, etc. The soils will also be field screened by noting evidence of odors,
staining and relative concentrations of volatile organic vapors using the PID. The one soil interval
exhibiting the most likely and/or highest evidence of impacts based on field screening will be selected as
the grab sample and submitted for VOC analysis, representing the sample area. A portion of the
remaining soil intervals from the borings within the sample area will be combined, mixed and the
composite sample will be collected from these soils and submitted for SVOC, total RCRA metals, and
hexavalent chromium analysis.

Additionally, one duplicate sample will be collected and analyzed for the same compounds (VOCs,
SVOCs, and RCRA Metals plus hexavalent chromium) and methods. See the attached Table 1 for a
summary of the soil sampling and analysis.

Assuming that unexpected soil conditions are not encountered, at the completion of the soil boring and
sampling activities, soil cuttings generated will either be placed back into the various soil borings or
spread onsite in the vicinity of the boring locations. Should groundwater be encountered within a
boring, bentonite will be added prior to topping the boring with soil cuttings. Each boring will be

completed by capping with asphalt, concrete, etc. to match the surrounding surface.

Groundwater Sampling

In accordance with the discussions during the above-referenced kickoff web meeting, ECS is proposing
to collect two groundwater samples via the installation of temporary monitoring wells using the DPT
drill rig. The proposed locations of the groundwater samples are indicated on Figure 5. The drilling and
well installation will be conducted by a North Carolina certified driller. The total depth of the temporary
monitoring wells will be determined based on field observation during the drilling activities. The
temporary monitoring well will be constructed with 1-inch diameter, Schedule 40 PVC slotted screen
and riser. The annular space around the PVC will be filled with clean quartz sand to a depth
approximately two feet above the screened interval then filled to the surface with hydrated bentonite.
The temporary monitoring wells will be developed by removing three to five well volumes of
groundwater.

The temporary monitoring wells will be sampled using low-flow sampling techniques and water quality
measurements including pH, temperature, conductivity, and turbidity will be collected/recorded. After
the water quality parameters have stabilized (pH within 0.1 Standard Units (SU), conductivity within 5%,
and turbidity less than 10 NTU or within 10%) across three readings (readings every 3 to 5 minutes), the
groundwater samples will be collected in laboratory provided containers and placed in an ice filled
cooler and maintained under chain-of-custody protocol. The groundwater samples will be submitted to
a North Carolina certified laboratory for chemical analysis of VOCs and SVOCs. The groundwater samples
will not be analyzed for RCRA metals in light of prior assessment data.

One duplicate and one MS/MSD groundwater sample will be collected and submitted for laboratory
analysis of VOCs and SVOCs. Additionally, one trip blank will also be analyzed for VOCs. See the attached
Table 1 for a summary of the groundwater sampling and analysis.

At the completion of the groundwater sampling activities, the temporary monitoring wells will be
properly abandoned. Assuming that unexpected soil conditions are not encountered in the field, soil
cuttings generated during the temporary monitoring well installation activities, and groundwater
generated during well development/sampling will be spread onsite in the vicinity of the boring location.

Soil Gas Sampling

In accordance with the discussions during the above-referenced kickoff web meeting, ECS is proposing
to collect nine soil gas samples below proposed site building footprints. Eight of the soil gas samples will
be located within the footprint of the proposed newbuilding planned for potential mixed commercial
and multifamily residential use, and one will be located on the eastern side of the proposed Phase II
structure that is currently planned for office/commercial/hospitality use, as indicated on Figure 5. The
soil gas sampling probes will be installed to a depth of 6 feet bgs. The borings for the soil gas sampling
probes will be advanced using a DPT drill rig. Once the borings have reached the desired depths, a
dedicated Nylaflow tubing and air stone will be lowered into the boring. Approximately one foot of clean

coarse sand will be placed around the air stone and a bentonite seal will be placed to a depth of
approximately 1 foot bgs and hydrated. The air stone and surrounding sand will be placed at depths so
that the minimum depth to the top of the sand is 5 feet bgs. The soil gas probes will be allowed to
stabilize for a minimum of four hours before the soil gas samples are collected. A dedicated syringe will
be used at each sample location and connected to the tubing to purge the tubing. Three volumes of the
tubing will be purged prior to sample collection.

Prior to collecting the soil gas samples, laboratory grade helium gas will be used as a quality assurance
control measure to confirm the integrity of the probe seal at each sample location. A shroud that
encloses the fittings and sample train will placed over the newly installed vapor point and filled with
helium. The sample tubing and tracer gas tubing will be placed through the shroud wall. During the
purging stage, the shroud will be flooded with laboratory grade helium via the hose placed through the
shroud wall. A Model MGD-2002 Multi-Gas Leak detector or similar will be connected to the probe tube
and the air stream being purged will be measured for helium. A helium concentration of less than ten
percent helium detected within the shroud will be considered acceptable. If concentrations greater
than ten percent helium is measured, the probe tube seal will be resealed and the leak detection
process will be repeated. In addition to the leak check, a shut-in test will be conducted to assess for
leaks in the fittings and regulator.

Following purging, the vapor point will be connected to a 1 L Summa canister, which will be used to
collect the sample. The Summa canister will be fitted with a flow regulator. The flow rate for both
purging and sample collection will be 0.2 liters per minute. The vacuum in the canister will be recorded
before and after sample collection. Sample collection will stop when the vacuum reaches approximately
5 inches of Hg. Other parameters that will be measured include ambient temperature before and after
sample collection and weather conditions at the time of sample collection.

Following sample collection, the Summa canisters will be labeled and maintained under chain-of-
custody until delivered to a certified and accredited laboratory (laboratory has not yet been selected). A
Chain-of-Custody document will be utilized throughout the collection and transportation of the samples.
Each sample will be analyzed for VOCs using EPA Method TO-15. The laboratory results will be reported
at or below the residential vapor intrusion screening levels (VISL) and J Flags (estimated concentrations
between the method detection limits and the laboratory reporting limit) will be reported.

Three duplicate samples will be collected using a “T” junction and analyzed for the same compounds
using EPA Method TO-15.

Brownfields 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.

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 TGACSE Central Square, LLC
representative and ECS after consultation with, and subject to approval by the NCBP. Such changes will
comply with applicable local, State, and Federal rules and regulations. A written amendment shall be
prepared and submitted to NCBP for approval (the use of e-mail correspondence shall suffice for
approval, followed by a hard copy or electronic copy provided on disk or similar media) prior to
implementation. Amendments must have the approval of the NCBP prior to implementation of each
amendment.

QA/QC

Soil, groundwater, and soil gas samples will be maintained under a chain-of-custody protocol and a Level
II QA/QC package will be requested. The soil and groundwater samples will be submitted to a North
Carolina certified laboratory for analysis. Since North Carolina does not certify laboratories for analyses
of air samples, ECS will request that the laboratory analyze air samples for the most current and
applicable standards from the National Environmental Laboratory Accreditation Program (NELAP).
Additionally, it will be requested that the method detection limits (MDL) and J-flags be included. The
sampling activities will be conducted in general accordance with Science and Ecosystem Support Division
(SESD) guidelines.

Waste Disposal

As previously stated, assuming that unexpected soil or groundwater conditions not are encountered in
the field, investigative derived waste (IDW) generated during field sampling activities will be thinly
spread onsite in the vicinity of the boring location/temporary monitoring wells, in accordance with the
NCDEQ, Inactive Hazardous Sites Branch requirements.

4.0 REPORTING

Upon receipt of all final laboratory reports, ECS will prepare a written report documenting the field
activities, sampling procedures, sample locations, laboratory procedures and results, conclusions, and
recommendations for submission and approval by the NCBP. Boring logs, well development forms, and
groundwater sampling field data will be included in the report along with the completed Brownfields
Property receptor survey. The report will include all applicable tables with comparisons against
applicable screening levels, figures depicting the sample locations and media sampled, and a
groundwater potentiometric map with a graphic scale and north arrow. The report will include the ECS
License Number and an individual North Carolina licensed PE/PG seal and signature.

The laboratory detections for the soil samples will be compared to the current NCDEQ, DWM
Preliminary Soil Remedial Goals (PSRGs) for Residential Health and Industrial/Commercial Health. The

laboratory detections for the groundwater samples will be compared to the current NCDEQ, NCAC 2L
Groundwater Quality Standards (NC2LGWQS) and the groundwater screening levels for Residential and
Non-Residential Vapor Intrusion Screening Levels (VISL). The laboratory detections of the soil gas
samples will be compared to the current sub-slab and exterior soil gas screening levels for Residential
and Non-Residential VISLs. Depending upon the detections and results, the values may also be further
evaluated using the NCDEQ, Rick Calculator. The results of this assessment are for the use of the NCDEQ
Brownfields Program.
