Final Grade Soil Sampling Work Plan Old Pineville Road Old Pineville Townhomes Charlotte, North Carolina Brownfields Project No. 10061-06-060 H&H Job No. NVR-010 1.0 Introduction

On behalf of NVR, Inc. (NVR), (Prospective Developer or PD), Hart & Hickman, P.C. (H&H)
has prepared this Final Grade Soil Sampling Work Plan (Work Plan) for the Old Pineville Road
Brownfields property (Brownfields Project No. 10061-06-060) located at 4928 Old Pineville
Road and 649 Scholtz Road in Charlotte, Mecklenburg County, North Carolina (Site or subject
Site). The redevelopment is known as Old Pineville Townhomes, and is being developed with
for-sale residential townhomes by Ryan Homes, an NVR company. The Site development plan
includes construction of fifteen (15) townhome complexes which includes one 3-unit townhome
complex, one 4-unit townhome complex, five 7-unit townhome complexes, and eight 8-unit
townhome complexes for a total of 106 individual residential townhome units. A Site location
map is included as Figure 1.

In accordance with the DEQ-approved Environmental Management Plan (EMP) dated January 3,
2020, final grade soil sampling will be conducted at the Site following redevelopment in areas
that are not covered with buildings, sidewalks, concrete or asphaltic paved (hardscape) surfaces,
or a minimum of two feet of demonstrably clean fill soil. H&H proposes to complete final grade
soil sampling activities to evaluate the potential for impacts in shallow soil within unpaved areas
where final grade elevations have been achieved at the Site. A discussion of the proposed final
grade soil sampling is provided below.

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 (Guidelines) dated
January 2020, 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.

On April 26, 2022, H&H completed an inspection of surface conditions at the Site and noted that
areas completed with townhome buildings are predominately covered with hardscape surfaces
with the exception of landscaped and/or grassy lawn areas along the central portion of the Site.
The townhomes located on the northern and southern Site boundaries do not have lawns and
have minimal landscaping near the entries. A Site Map is included as Figure 2 and general
surface conditions and proposed boring locations are shown on Figure 3. A photographic log of
landscaping conditions observed during the April 2022 Site visit is included as Appendix A.

Final grade soil sampling will be completed with collection of samples for laboratory analysis
across the completed Site where final grade elevations have been achieved. Details for the final
grade soil assessment activities are provided in the following sections.

2.1 Final Grade Soil Sampling Activities
Based on review of the Site Plan and observations at the Site, landscaped areas in the central
portions of the Site have been divided into fifteen (15) final grade evaluation areas (FG-1
through FG-15). 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.

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 fifteen (15) 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 fifteen (15) 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.

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
per day of sampling that will be submitted for the same analyses as the parent soil sample.

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 IHSB
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 (i.e., elevated PID readings) 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 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 a 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, completed risk calculators, and conclusions based upon our
assessment activities. The report will be sealed by a North Carolina Professional Engineer (PE)
or Licensed Geologist (LG) and the firm PE/LG numbers will be provided.
