1.0 Introduction

On behalf of Boulevard at 4920 Old Pineville, LLC, (Prospective Developer or PD), Hart &
Hickman, P.C. (H&H) has prepared this Final Grade Soil Sampling Work Plan (Work Plan) for
the Blythe Isenhour Brownfields property (Brownfields Project No. 23067-19-060) located at
4920 Old Pineville Road in Charlotte, Mecklenburg County, North Carolina (Site or subject
Site). The redevelopment is known as Old Pineville Towns Phase II, and is being developed
with for-sale residential townhomes by Ryan Homes, an NVR company. The Site development
plan includes construction of forty-eight (48) individual townhomes units across twelve (12)
building slabs. A Site location map is included as Figure 1, and the Site and surrounding area are
shown in Figure 2.

In accordance with the North Carolina Department of Environmental Quality (DEQ) approved
Environmental Management Plan (EMP) executed on December 23, 2020, final grade soil
sampling will be conducted at the Site in areas that are not covered with buildings, concrete or
asphaltic paved (hardscape) surfaces, or a minimum of two feet of demonstrably clean fill soil.
Redevelopment of the Site is underway and final grade has been achieved at the subject Site.
Landscaped and hardscaped portion of the Site are shown in Figure 3. A discussion of the
proposed final grade soil sampling is provided below.

soil sampling work plan_blythe isenhour.doc
2.0 Final Grade Assessment Activities

Final grade soil sampling activities will be conducted at the Site to evaluate potential direct
exposure risks to future Site occupants and workers from shallow soil in landscaped areas. The
soil sampling activities will be conducted in general accordance with the DEQ Inactive
Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites
(Guidelines) dated July 2021, and the most recent versions of U.S. Environmental Protection
Agency (EPA) Region IV Laboratory Services and Applied Science Division (LSASD) Field
Branches Quality System and Technical Procedures guidance.

Prior to conducting the proposed assessment field activities, H&H will contract North Carolina
811, the public utility locator, to mark subsurface utilities located on the Site. Additionally, soil
boring locations will be hand cleared utilizing stainless steel hand augers to further screen the
boring locations for the presence of subsurface utilities.

2.1 Final Grade Soil Sampling Activities

Based on review of the Site Plan, landscaped areas at the Site have been divided into ten (10)
final grade evaluation areas (FG-1 through FG-10). Up to five shallow soil borings will be
advanced within each final grade evaluation area for collection of aliquot soil samples from each
shallow soil boring. Soil sample aliquots collected from each evaluation area will be
homogenized to form one composite soil sample to represent shallow soil conditions in that
evaluation area. The final grade evaluation areas and approximate locations of the aliquot soil
borings are shown in Figure 3.

Aliquot soil borings will be advanced from the surface to approximately two feet below the
ground surface (ft bgs) using a decontaminated stainless-steel hand auger. During boring
advancement, continuous soil samples will be collected from the center of the hand auger bucket.
Soil samples will be described for lithologic purposes, observed for obvious evidence of staining
and unusual odors. A portion of the soil sample will be allowed to volatilize and will be field
screened for the presence of volatile organic vapors using a calibrated photoionization detector.

realty estate advisors (bou)/bou-014 4920 old pineville rd/final grade/work plan/23067 - final grade
soil sampling work plan_blythe isenhour.doc

Remaining portions of the aliquot soil samples will be homogenized to form a composite soil
sample representative of each evaluation area for a total of ten (10) composite final grade soil
samples. Soil samples selected for laboratory analysis will be collected directly into laboratory
supplied glassware, 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 the analyses outlined
below.

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 plus hexavalent chromium by EPA Methods 6020/7471/7199. In addition, one grab
sample will be collected from an undisturbed portion of an aliquot soil sample collected in each
evaluation area for a total of ten (10) grab soil samples that will be submitted for analysis of
volatile organic compounds (VOCs) by EPA Method 8260. A final grade soil sample summary
is provided as Table 1.

The grab samples collected for VOC analysis will be selected based on results of field screening
and collected from the aliquot exhibiting the highest likelihood for impact in each final grade
evaluation area. If field screening results do not identify obvious presence of impacts in an
aliquot soil sample, the final grade evaluation area grab samples will be collected from the 1 to 2
ft bgs sample interval from a randomly selected aliquot soil boring in each evaluation area.

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

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 for the same analyses as the parent soil sample.

realty estate advisors (bou)/bou-014 4920 old pineville rd/final grade/work plan/23067 - final grade
soil sampling work plan_blythe isenhour.doc

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
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 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 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.

2.3 Investigation Derived Waste

Investigation derived waste (IDW) generated during the assessment activities will be thin spread
on-Site. However, if significant impacts are suspected based on field screening results, the soil
cuttings 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 transported off-Site to a suitable facility for disposal. IDW generated during the
proposed assessment activities will be managed in general accordance with DEQ IHSB
Guidelines.

2.4 Reporting

Following completion of the soil assessment activities in each completed area of the Site and
receipt of the analytical data for samples collected in that area, H&H will prepare data summary
package for submittal to DEQ. The data summary package will include a tabular summary of the
laboratory analytical results, a sample location map, a copy of the laboratory analytical report,
and completed risk calculators.

Following completion of the final grade soil assessment for the Site, a report which describes the
methods and results of the final grade soil sampling activities will be prepared and submitted to
DEQ. The report will include a description of field activities, field screening results, a tabular
summary of the analytical results in comparison to the PSRGs, risk calculations, boring logs in
tabular form (will include boring IDs, field screening/PID results, and soil descriptions), figures
depicting the sample locations, laboratory analytical reports and chain of custody records, a
discussion of QA/QC data, and conclusions based upon our assessment activities. The report
will be sealed by a North Carolina Professional Engineer (PE) or Professional Geologist (PG)
and the firm PE/PG numbers will be provided.
