Dear Carolyn:

1.0 Introduction

On behalf of CC Rapid Commerce Park Owner, LLC (Prospective Developer or PD), Hart &
Hickman, PC (H&H) has prepared this Final Grade Soil Sampling Work Plan (Work Plan) to
conduct final grade soil sampling activities at the Rhyne Road Brownfields Property (Brownfields
Project No. 26016-22-060) located at 438-614 Rhyne Road in Charlotte, Mecklenburg County,
North Carolina (Site). A Site location map is provided as Figure 1.

The Site consists of one approximately 37-acre parcel of land improved with an industrial park
known as Rapid Commerce Park in conjunction with the adjacent Brownfields property at 2515-
2622 Verde Creek Road which will be developed by Beacon RCP, LLC. The Rapid Commerce
Park project is being completed jointly by the PD and Beacon RCP, LLC. Historically, the Site
was comprised of nine contiguous parcels that were developed with five single-family residences

with multiple outbuildings located in the northern, central, and eastern portions of the Site and an
approximately 3,900-square foot (sq ft) vacant commercial building in the eastern portion of the
Site. The western and southern portions of the Site were undeveloped land with an unnamed
tributary of Long Creek.

Ongoing redevelopment on the Site includes the construction of one industrial warehouse building
and associated access roads, parking areas, and loading docks. Redevelopment activities are
proposed to be completed by late summer 2024.

An Environmental Management Plan (EMP) for the Site was approved by the North Carolina
Department of Environmental Quality (DEQ) Brownfields Redevelopment Section on November
8, 2022. The EMP includes a requirement for collection of final grade soil samples in areas that
are not covered with a minimum of 2 ft of demonstrable clean fill soil or topsoil from a landscaping
company, building foundations, sidewalks, asphalt or concrete parking areas, or other impervious
surfaces following completion of redevelopment activities.

This Work Plan has been prepared to detail proposed final grade soil sampling activities in
accordance with the DEQ-approved EMP. The proposed final grade soil sampling scope of work
is provided below in Section 2.0.

2.0 Final Grade Soil Sampling Scope of Work

The purpose of the final grade soil assessment activities is to evaluate potential direct exposure
risks to future Site occupants and workers from shallow soil in landscaped areas at the Site. An
Overall Landscape Compliance Plan prepared by Orsborn Engineering Group dated April 14, 2023
is provided as Appendix A.

The soil sampling activities described herein will be performed in accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated September
2023, the most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Lab
Services and Applied Sciences Division (LSASD) Field Branches Quality System and Technical

Procedures guidance, and the DEQ Brownfields Minimum Requirements Checklist for Site
Assessment Work Plans and Reports dated March 2023.

2.1 Final Grade Soil Sampling Activities

Based on review of the Overall Landscape Compliance Plan, observations at the Site, and
communications with the PD, landscaped areas are present adjacent to the proposed building and
along the Brownfields property boundary. These areas have been divided into six final grade soil
evaluation areas (FG-1 through FG-6) and will include four to five shallow soil borings advanced
to approximately 2 ft below ground surface (bgs) in each of these areas. A final grade soil sample
summary is provided as Table 1. The six final grade evaluation areas and approximate locations of
the aliquot soil boring locations are shown in Figure 2. Note that the southwestern portion of the
Brownfields Property includes an undisturbed wooded area that is not part of redevelopment plans
and is therefore not included as an assessment area in this Work Plan.

Each aliquot soil boring will be advanced to a depth of approximately 2 ft bgs using a
decontaminated stainless steel hand auger. Soil samples will be collected from each boring at 1-ft
intervals and screened in the field for the presence of potential soil impacts. Field screening will
include observations for the presence of unusual odor and staining that could be indicative of soil
contamination. In addition, soil will be placed in sealed plastic bags and screened for the presence
of organic vapors using a calibrated photoionization detector (PID). Undisturbed soil from each
depth interval will be set aside for collection of a grab sample for volatile organic compound (VOC)
analysis and will not be used in the screening process.

Based on field screening results, one grab sample will be collected from each final grade evaluation
area for laboratory analysis of VOCs by EPA Method 8260. If field screening results do not identify
obvious presence of impacts in an aliquot soil sample, the grab soil samples will be collected from
the 1 to 2 ft bgs sample interval from a randomly selected aliquot soil boring in each evaluation
area for a total of six grab soil samples for analysis of VOCs. As noted above, the grab samples for
laboratory analysis of VOCs will be collected from undisturbed soil that was not used for field
screening.

In addition, four to five soil sample aliquots collected from the borings advanced in each of the six
designated evaluation areas will be homogenized to form one composite soil sample representative
of shallow soil in that area for a total of six composite final grade soil samples. Composite soil
samples will be submitted for laboratory analysis of semi-volatile organic compounds (SVOCs) by
EPA Method 8270, Resource Conservation and Recovery Act (RCRA) metals by EPA Methods
6020/7471, and hexavalent chromium by EPA Method 7199.

The soil samples selected for laboratory analysis will be placed in dedicated laboratory-supplied
sample containers, labeled with the sample identification, date, time, requested analysis, and placed
in a laboratory-supplied cooler with ice. The samples will be submitted to a North Carolina-
certified laboratory under standard chain-of-custody protocols.

Following sampling activities, the soil sample locations will be estimated using a hand-held global
positioning system (GPS) unit.

2.2 Quality Assurance/Quality Control

Non-dedicated equipment and tools will be decontaminated prior to use at each boring location. To
evaluate the reproducibility of the sample results, H&H will collect one duplicate soil sample that
will be submitted to the laboratory for the same analyses as the parent soil sample.

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 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.

H&H will request that laboratory method detection limits for each analyte be at or below the DEQ
Residential Preliminary Soil Remediation Goals (PSRGs), 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 the final grade soil samples will be
provided in an appendix to the final report. Laboratory QA data consistent with Level II
documentation will be requested 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.

3.0 Soil Boring Abandonment and Investigation Derived Waste

Following sampling activities, the soil borings will be properly abandoned and the surfaces will be
repaired similar to pre-drilling conditions.

Investigation derived waste (IDW) generated during the sampling activities will be thinly spread
on-Site. If there is evidence of significant impact (such as free product), the IDW will be
containerized in 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 managed in
accordance with DEQ IHSB Guidelines and the 15A NCAC 02T.1503 and 15A NCAC 02H. 0106
rules and transported off-Site to a suitable facility for disposal.

4.0 Reporting

Following completion of the final grade soil sampling activities and receipt of the analytical data,
H&H will prepare a report describing the sampling methods and analytical results. The report will
include a description of the soil sampling activities, figures depicting the sample locations, a tabular
summary of the analytical data, a discussion of the data in comparison to regulatory screening
levels, risk calculations, laboratory analytical reports including chain-of-custody records, a
discussion of QA/QC data, and conclusions based upon our assessment activities. The report will
