Dear Ms. Minnich:
Wood Environment &Infrastructure Solutions, Inc. (Wood) is pleased to submit this Work Plan
outlining activities proposed for the above-referenced site. Included in this Work Plan is an
outline of our understanding of the project information, our proposed scope of services and
schedule.
PROJECT INFORMATION
The entire site consists of one tax parcel (Tax ID 073-064-26)totaling 2.264 acres (Figure 1).
The site is located in a mixed use area within the Gold District section of South End near uptown
Charlotte, North Carolina. Golden Nugget Associates, LLC, an entity of Spectrum Development
Company, LLC (Spectrum) plans to redevelop the subject property.In 2019,Wood completed a
Phase I Environmental Assessment (ESA) for the subject parcels.The assessment revealed

evidence of recognized environmental conditions (RECs) in connection with the site including the
following.
Occupation of the site by owners/tenants involved in industrial activities such as
cleaning, textile manufacturing, printing, and a machine shop is considered to be a REC;
The identified automotive facilities on the upgradient or cross gradient properties
located at 309 and 321 West Palmer Street and 1201 South Mint Street have the
potential to negatively affect the site;
The documentation of non-compliance and enforcement actions at the Electrical
Apparatus portion of the site is considered a REC.
Subsequently, Wood performed sampling and analysis of soil, soil-gas and groundwater at 308
W. Palmer Street and 308 W. Carson Boulevard. The second phase of assessment included
sampling and analysis of soil, soil-gas and groundwater at the parcels associated with addresses
1115 and 1127 S. Mint Street and 308 W. Carson Boulevard.The results of the sampling and
analysis are summarized as follows:
The metals concentrations identified in the soil samples are within the range of
“naturally-occurring” metals for soils according to published literature. Hexavalent
chromium was identified in sample SB-5 at a concentration that slightly exceeded the
Residential Preliminary Soil Remediation Goals (PSRGs).The historic soil analytical results
are shown on Table 1.
The concentrations of Tetrachloroethylene (PCE) identified in soil-gas samples SG-1 and
SG-2 and the concentrations of 1,3-butadiene in soil-gas samples SG-1, SG-3 and SG-4
exceeded their respective NCDEQ Residential Soil-Gas Vapor Intrusion Screening Levels
(VISL). Therefore, the data suggests that there is potential for vapor intrusion into
structures, particularly in the area of the Electrical Apparatus and Machine Company.
Most notably, carbon tetrachloride was identified in two groundwater samples (MW-1
and MW-2). Carbon tetrachloride is a chlorinated organic solvent. It was formerly widely
used in fire extinguishers, as a precursor to refrigerants and as a cleaning agent, but has
since been phased out because of toxicity and safety concerns.
In late 2019, the Prospective Developer (PD) applied for eligibility to the North Carolina
Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM),
Brownfields Program (BFP). An eligibility letter (dated March 27, 2020) was issued by the BFP.
The Prospective Developer (PD) recently provided a soil cut/fill analysis that showed up to
19,000 cubic yards (yds3) will be excavated from the property and will likely require export to an

off-site location.To evaluate potential soil export options, it will be necessary to perform
characterization of the soil that will likely need to be exported off-site.According to the cut/fill
analysis (Figure 2)provided to Wood, the reduction of the grade elevation will range from 0.5
to more than 15 feet across the site.This work plan was developed to provide a scope of work
relative to the assessment of the mass grading planned for the subject properties.The resulting
data will be provided to the BFP for review.The proposed assessment activities will be
performed in general accordance with the most recent Inactive Hazardous Sites Branch (IHSB)
Program Guidelines for Assessment and Cleanup dated January 2020
(https://files.nc.gov/ncdeq/Waste%20Management/DWM/SF/IHS/guidance/IHSB_RemediationG
uidance012720.pdf)and the most recent versions of the U.S. Environmental Protection Agency
(EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System
and Technical Procedures guidance.
PROPOSED SCOPE OF WORK
Task 1 –Beneficial Reuse Soil Characterization
Wood proposes to advance 96 shallow soil borings at locations throughout the site (see
attached Figures 2 and 3)to assess the area to be affected during mass grading.The 96
borings are “grouped” into 15 sample “block” areas as shown on Figure 3. The boring layout
shown on the figures is based on a 30 x 30 foot grid pattern. The boring locations approved by
the BFP will be marked in the field and recorded on a hand-held GPS unit for future reference.
The soil assessment/characterization effort is planned to evaluate several “depth horizons”
relative to the existing grade for the presence of contaminants. The depth horizons include 0 to
5,5 to 10,10 to 15 feet below the existing grade at the property.Wood anticipates initiating
characterization work on or around May 8, 2020 on the northeastern portion of the site where
no buildings are present. Because demolition of the site buildings is needed to access the
central and southwestern portions of the property, Wood anticipates field characterization of
this area will be performed in late May 2020.
The soil assessment/characterization effort is planned to evaluate the depth horizons beginning
at the existing grade and extending to various depths across the property for the presence of
contaminants.The purpose of the soil characterization is to evaluate if concentrations of
contaminants are identified in the soil to be exported that exceed the IHSB,PSRGs for
Residential or Protection of Groundwater (PoG).

Prior to conducting the soil assessment activities,Wood will contact the North Carolina 811
underground utility location service and a private underground utility locator to perform
Ground-Penetrating Radar (GPR) and Electromagnetic (EM) surveys to attempt to detect metallic
objects such as pipes, tanks or underground utility lines. The purpose of this effort is to
minimize the potential for probing into underground utilities buried at the property.
Wood’s direct-push subcontractor will advance the soil borings to depths ranging from five to
15 feet below existing grade using a direct-push rig (see attached Table 2). These proposed
depths are based on our knowledge of the depth to groundwater and/or bedrock and
reasonable preliminary “cut” elevations. Wood plans to refer to the cut/fill analysis to collect the
soil cores at each boring location from the depth range shown on the cut/fill analysis (see Table
2).The probing contractor will collect soil cores as directed by the field geologist. Beginning at
the existing grade, the probing contractor will collect soil cores by advancing direct-push tooling
at five-foot depth intervals (see Table 2). Soil cores will be removed from the disposable PVC
liners, and visual and olfactory observations relative to the soil samples will be recorded by our
field personnel. The soil types encountered in the borings will be recorded to prepare soil boring
logs.
To select “discrete”samples that will be retained for analysis of Volatile Organic Compounds
(VOCs),Wood will split the soil core longitudinally. A representative portion of one-half of the
sample will be placed directly in VOC sample containers and a representative portion of the
remaining half will be placed in a re-sealable plastic bag to be screened in the field using an
Organic Vapor Analyzer (OVA) equipped with either a photoionization detector (PID) or flame
ionization detector (FID). The results of the field screening will be recorded by field personnel.
Based on the results of the field screening, one “discrete”sample per block area will be selected
for laboratory analysis for VOCs using EPA Method 8260D.
Regarding the samples to be retained for analysis of Semi-volatile Organic Compounds (SVOCs)
and metals,representative portions of the soil cores collected from the appropriate depth
interval will be placed in re-sealable plastic bags and screened in the field with an OVA. The
results of the field screening will be recorded by field personnel. The soil samples will be
removed from the resealable plastic bags and be placed in laboratory sample containers.These
“discrete” samples will be combined in the laboratory by laboratory personnel as a
“composite” sample as shown on the attached Table. Each “composite” soil sample will be
placed into laboratory-provided containers for analysis of SVOCs by EPA Method 8270E and
Work Plan for Soil Characterization May 1, 2020WoodProject: 6228-19-0534

Resource Conservation and Recovery Act (RCRA) Metals (total) by EPA Method 6020/7471. Upon
receipt and review of the total chromium data, Wood will select five composite samples for
analysis for Hexavalent Chromium (by Method 7199)to speciate the identified chromium as
either trivalent or hexavalent.
The soil samples will be placed in a cooler with ice and shipped to Con-Test Analytical
Laboratory (Con-Test)in East Longmeadow, Massachusetts.Con-Test is certified by the State of
North Carolina (Certification No. 652).Soil samples will be maintained under a chain-of-custody
protocol. One soil field duplicate QA/QC sample will be collected for each day of field work for
analysis of VOCs, SVOCs and metals.No trip blank is proposed for relative to the soil samples.
Following the completion of the soil sampling activities, the borings will be backfilled with the
soil cores and/or bentonite to the ground surface.Excess soil cores will be spread on the ground
surface at the site.
Task 2 –Prepare Beneficial Reuse Assessment Report
Wood will prepare a Beneficial Reuse Soil Assessment report summarizing the field activities,
results, and conclusions for Golden Nugget Associates,LLC and NCDEQ to review.This report
will include a description of field activities, tabulated data and the laboratory data packet with
applicable Level II QA/QC documentation with “j flags” reported.A site map and subsurface
profile drawings will be provided with the report. The purpose of the report will be to provide
data in a manner that will allow Golden Nugget Associates, LLC, and grading contractor to
evaluate the location and depth of “non-contaminated” soil that may be suitable for beneficial
reuse elsewhere.The report will include a comparison of the results to the IHSB, PSRGs and a
graphical presentation of the analytical data on site drawings to illustrate which “grid squares”
and depth horizons include “non-contaminated” soil.Soil analytical results will be considered
representative of the proposed “cut” depth horizon, “grid square” or “sample block area” which
they are located within.At the request of Golden Nugget Associates, LLC. The report will be
submitted to the NCDEQ BFP for review and approval.
